Avaliação da qualidade da assistência aos portadores de úlceras venosas atendidos no ambulatório de um hospital universitário em Natal/RN

Study descriptive that was designed to assess the quality of care for people with venous ulcers (VUs) tended at the ambulatory of a university hospital in Natal / RN. The target population of the study was composed by 40 users bearers of venous ulcers served in the ambulatory of angiology of a university hospital in the level of tertiary education. The study received assent of the Ethics Committee of the Federal University of Rio Grande do Norte (Protocol No. 169/06). The collect of data was performed using a form of interview and tour with collection of measures biophysiologic, for a team comprised by the researchers and an academic of nursing, in the period of three months. The data were analyzed in SPSS 14.0, using descriptive statistics and presented in the form of charts, tables and graphs. Identified a clientele of holders of VUs predominantly female, married, aged up to 59 years, low level of education and household income, from Natal, retirees or those exercising professions and occupations that require long periods standing or sitting. In relation to the characteristics of health, those surveyed had risk factors for venous disease and had UVs chronic, located in Zone 2, lost tissue in grade II and serous exudates on average quantity. The assistance to holders of UVs has been characterized by a lack of professional nurses and unavailability of products for the realization of the right curative in ambulatory and outside it; by the inadequacy of products used in VUs, for long periods of treatment without resolution, where the compressive therapy is not priority, by the lack of completeness in the levels of assistance; by monitoring the bearer of UVs only by doctors and the nurses, even with the other team of professionals in the health service; by the completion of guidelines by health professionals and the lack the standardization of conducting laboratory and specifics tests. The assistance was assessed as inadequate in aspects: reference and counter-reference (75.0%), number of consultations with angiologists last year (87.5%), documentation of the clinical findings (85.0%), use of compressive therapy in the past 30 days (77.5%), part of the team interdisciplinary (97.5%), completion of laboratory and specifics tests in the last year (100%), availability of products used in achieving the curative in ambulatory (80, 0%), and indication of products used in the conduct of dressing outside the clinic (70.0%) and appropriate in the guidelines made on the use of socks, lifting of the members and prescription of exercises regular (82.5%) and indication products used in achieving the curative in ambulatory (97.5%). We conclude that the assistance provided to holders of UV was inadequate in 80% of cases interviewed, becoming non-resolutive and assistematic

Adubação nitrogenada em cultivares de arroz de terras altas

O objetivo deste trabalho foi avaliar a influência de diferentes doses de N em cobertura (0, 30, 60, 90 e 120 kg ha-1) sobre as características agronômicas de diferentes cultivares de arroz de terras altas (Caiapó, Primavera, Confiança, IAC 202 e Carisma) sob irrigação por aspersão durante os anos agrícolas 2003/04 e 2004/05, em área experimental da FCAV - UNESP - Jaboticabal (SP). Os cultivares Caiapó, IAC 202 e Carisma são os de maior produtividade, com o Primavera não respondendo ao incremento da adubação nitrogenada; o IAC 202 e Carisma são possuidores de índice de colheita mais elevado e responsivos ao nitrogênio aplicado em cobertura, sugerindo-se indicá-los para sistemas produtivos mais evoluídos; o cultivar Caiapó demonstra ser mais eficiente em absorver e utilizar o N contido no solo, sugerindo sua indicação para sistemas produtivos de menor aporte de tecnologia.

Nitrogênio na produção e qualidade de sementes de feijão

O uso de fertilizante nitrogenado, em campos de produção de sementes, pode beneficiar a produtividade e a qualidade da semente, por afetar a formação do embrião e dos órgãos de reserva. Assim, objetivou-se, com este trabalho, avaliar a produção e o potencial fisiológico de sementes de feijoeiro, em função da aplicação de nitrogênio em cobertura, em duas cultivares. Utilizou-se o delineamento de blocos casualizados, em esquema fatorial 2×6, com 12 tratamentos (cultivares Pérola e IAC Carioca Eté e seis doses de nitrogênio em cobertura: 0 kg ha-1, 30 kg ha-1, 60 kg ha-1, 90 kg ha-1, 120 kg ha-1 e 150 kg ha-1) e quatro repetições. O nitrogênio promoveu aumentos na produção de sementes, com dose ótima de 143 kg de N ha-1, para a cultivar Pérola, e 134 kg de N ha-1, para a cultivar IAC Carioca Eté, com a Pérola apresentando maiores níveis de produtividade. Alterações na qualidade de sementes não foram verificadas com o aumento das doses de nitrogênio.

Qualidade da assistência e o conhecimento sobre o direito à saúde das pessoas com úlcera venosa crônica

The study aimed to identify the quality of care and knowledge of health rights of people with chronic venous ulcers (VU) in Brasilian National Health Care System (SUS). It is a cross-sectional study, with quantitative approach, performed at the University Hospital Onofre Lopes (HUOL). The study was approved by the Ethics Committee of HUOL (CAAE nº 0148.0.051.000-10). The sample by accessibility was composed for 30 people with VU treated at the outpatient surgical clinic of HUOL. For data collection we used a structured questionnaire composed of two parts: sociodemographic characteristics and of health, of care and the clinical course of VU; and knowledge of people with VU about the rights of health. The results were processed using SPSS 15.0 and analyzed by descriptive statistics. Given the characterizations sociodemographic and health presented, we identified a clientele of users with VU predominantly female (76,7%), aged from 60 years (66,7%), married/ stable union (60,0%), low education level (83,3%), family income lower than a minimum wage (73,3%), unemployeds and with chronic diseases (53,3%), sleep greater than or equal to 6 hours (76,7%) and were not alcoholics or smokers (93,3%). In relation to clinical conditions, were shown the presence of one or more relapses of VU (73,3%), predominance of granulation tissue/epithelialization in the bed of VU (60,0%), exudate serosanguineous (43,3%), in quantity medium/large (60,0%), with no predominance of presence or absence of odor (50,0%), all patients with tissue loss in grade III / IV, no signs of infection (73,3%) and presence of intense pain (50,0%). In the last 30 days the main venue of achievement of dressing was the HUOL (100,0%), the main compression therapy used was the Unna boot (60,0%) and on inability to perform the dressing on the unit were the own patients who made the exchange at home (40,0%). The majority of respondents listed out more positive factors associated with quality of care (56,7%) were satisfied with the care of SUS (76,7%), claimed to have knowledge about their rights (70,0%), but at the same time did not know the meaning of the acronym SUS (90,0%) and classified their level of information as inappropriate (70,0%). We realize that people with VU identified as good the quality of care and demonstrated inadequate knowledge about their rights to health in the SUS, but showed interest in acquiring more information. The basic rights to entry in the SUS are constitutionally guaranteed and need to be disseminated in order to make them known to the population, so it can be implemented and ensured a greater resolution assistance in treating this type of injury

Características agronômicas de arroz de terras altas sob plantio direto e adubação nitrogenada e potássica

O objetivo do presente trabalho foi avaliar o efeito da adubação nitrogenada e potássica em cobertura na cultura de arroz de terras altas, utilizando um delineamento estatístico inteiramente casualizado, com 15 tratamentos, em esquema fatorial 5 x 3, representados por cinco doses de nitrogênio (0, 25, 50, 75, 100 kg ha-1) e três doses de potássio (0, 25, 50 kg ha-1), com três repetições. Os resultados mostraram que diversas características produtivas foram influenciadas positivamente pela adubação nitroggenada e potássica. A melhor combinação de doses estaria em torno de 65 kg ha-1 de N e 20 kg ha-1 de K2O, resultando em maiores valores de produtividade e proteína bruta por hectare.

Diagnósticos de enfermagem em pacientes submetidos à hemodiálise: semelhanças entre o modelo de adaptação e a NANDA internacional

The nurses in the hemodialysis has an important role in the nursing process implementation, in the context of a theoretical referential. Among the nursing theories, highlights the Roy´s adaptations model, who considers a person as an holistic adaptive system that aims to adapt customers to different living conditions. Thus, it is believed that the Roy´s nursing process will guide nursing care to patients on dialysis. Therefore, the study aimed to analyze the nursing diagnosis present in patients with chronic kidney disease on hemodialysis based on the theoretical model of Roy and NANDA-International. Descriptive and cros-sectional study, performed at a dialysis center in a city in northeastern Brazil. Sample of 178 patients and consecutive sampling by convenience. Data collection ocurred from October/2011 until February/2012, through interview and physical examination forms. Data analysis was initiated by clinical reasoning, diagnosis judgment and similarity relation. Then, the data were entered into SPSS program, 16.0 version, generating descriptive statistics. The project was approved by the Ethics Research Committee (protocol nº 115/11) with a Presentation Certificate for Ethics Appreciation (in 0139.0.051.000-111) and was funded by the Universal edict MCT / CNPq 14/2010. The results revealed that most patients were male (52.2%), married (62.9%) and residents in the Natal´s metropolitan region (54.5%). The mean age was 46.6 years and the years of study, 8,5. Regarding nursing diagnosis obtained an average of 6.6, especially: Risk of Infection (100%), excessive fluid volume (99.4%) and hypothermia (61.8%). On the other hand the adaptive problems average was 6.4, and the most common: intracellular fluid retention (99.4%); Hyperkalemia (64.6%); Hypothermia (61.8%) and edema (53.9%). Were established 20 similarity relations between the NANDA-International nursing diagnosis and adaptive problems of Roy, namely: risk of falls / injury risk and potential for injury, impaired physical mobility and walking mobility and / or restricted coordination, dressing self-care deficit and loss of self-care ability; hypothermia and hypothermia; impaired skin integrity and impaired skin integrity; excessive fluid volume and intracellular fluid retention / Hyperkalemia / Hypocalcemia / edema; imbalanced nutrition: less than body requirements and Nutrition less than the body's needs; constipation and constipation, acute pain and acute pain, chronic pain and chronic pain, sensorial perception disturbed: visual, tactile and auditory disabilities and a primary sense: sight, hearing and tactile; sleep deprivation and insomnia, fatigue and intolerance to activities; ineffective self health and fails in the role; sexual dysfunction and sexual dysfunction; situational low self-esteem and low self-esteem, and diarrhea and diarrhea. We conclude that there is similarity between the typologies and was required a model´s analysis, because they present different ways to establish the nursing diagnosis. Moreover, the nursing process use, under the context of a theory and a classification system, subsidizes the care and contributes to the strengthening of nursing science

Autoestima e qualidade de vida de pessoas com úlcera venosa atendidas na atenção primária

Venous ulcers (VU) is a chronic injury of the lower extremities and because of its high incidence and recurrence implies long and complex treatments, damaging the quality of life (QOL) and self-esteem (SE) of the people. This study aimed to analyze the association between self-esteem with the quality of life of people with venous ulcers treated in primary care. Cross sectional analytical study with a quantitative approach conducted with 44 people met with VU at 13 primary care units 2 and Mixed units in Natal/RN. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte (UFRN), CAAE: 07556312.0.0000.5537. Held data collection from February to April 2014 and used three instruments: a structured form covering sociodemographic, health care and clinical variables, the Rosenberg Self-Esteem Scale and the SF-36. The collected data were entered into a database and processed on computerized software for descriptive and inferential analyzes. The results showed a predominance of people with UV females (65,9%), with more than 60 years (59,1%), married or in a stable relationship (52,3%), low education (86,4%) without occupation (68,2%) and less than one minimum wage income (81,8%). Regarding assistance characteristics was observed that most patients performed the dressing with appropriate material (72,7%), professional or trained caregiver (61,4%) did not use compression therapy (81,8%), treating the injury for more than 6 months (77,3%), lack of guidelines for the use of compression therapy, elevation of legs, and regular exercise (77,3%) and consulting the angiologist last year (52,3% ). Regarding clinical features of the lesion was found that most of the recurrent lesions are (77,3%), over one year of current lesion (52,3%) medium to large lesions (54,8%), without signs of infection (61,3%) and pain (79,5%). The mean SE of respondents was 9,3 (± 5,1). The relations between the SE and the sociodemographic variables, health care and clinics showed that individuals without a partner (a) (p = 0,01), who did not wear compression therapy (p = 0,04), with more 6 months of treatment (p = 0,01) and larger lesions (p = 0,01) had a lower SE. The mean domain and the dimensions of the SF-36 were lower emphasizing the functional capacity 36.5 (± 27,6) and the physical aspects of 15.3 (± 30,6). There were significant correlations between AE people with VU and the domains and dimensions of the SF-36: physical functioning (r = -0,432), general health (r = -0,415), vitality (r = -0,573), aspects social (r = -0,517), mental health (r = -0,612) and mental health dimensions (r = -0,612) and physical health (r = -0,473). Based on these results it is concluded by rejecting the null hypothesis and accept the alternative proposed in the study in which it was found that there is a negative correlation between the SE and the QOL of people with venous ulcers

Avaliação da assistência à saúde dos portadores de úlceras venosas atendidos no programa saúde da família do município de Natal/RN

Descriptive research aimed at evaluating the assistance offered to patients with venous ulcers, on lower limbs, attended by the Family Health Program (FHP) team, from the municipality of Natal/RN. The target population was composed of 74 patients with venous ulcers (VU), attended by the FHP teams in the 31 FHUs. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (protocol n.55/05). The data collection was performed in patients homes and in the FHUs, through structured interviews and physical examinations of patients with VU and non-participant observation during the changing of wound dressings in these Units and in users homes. The data was organized into an Excel electronic table and transported into the SPSS 14.0 program, for descriptive analysis on 2x2 contingency tables and inferential (Qui-Square χ2, Spearman Correlation, Binomial Proportion Test and p-value <0.05). The prevalence of VU (0.36/1000) in the target population (over 20 years of age) was greater than in the population registered in FHP (0.25/1000). We detected a greater prevalence in the age area of over 60 years (2.22/1000), with 2.98/1000 for females and 1.3/1000 for males (p-value=0.008). The sociodemographical and health characteristics of patients with VU revealed predominance of females (74.5%), elders over 60 years of age (67.6%), with fundamental education (74.3%), family earnings of up to 2 minimum wages (68.9%), retired (90.5%), ortostatic position (23.0%), inadequate sleep (59,9%), presence of CVI (100.0%), hypertension (44.6%) and diabetes (25.7%). As for the time of existence of the VU, 64.9% had over 1 year, and 35.1% less than 1 year), with predominance of one wound (67.6%). The changing of wound dressings is performed mostly at home, in and inadequate way, especially with incorrect cleaning techniques, likewise incorrect use of products and substances, and reduced participation of the FHP team on the evaluation and application of the dressing and choosing of products and substances. The compressive therapy is not part of therapeutic conducts for treatment in the FHUs. As for the evaluation of assistance to patients with VU, 90.5% were inadequate and only 9.5% adequate. The main inadequacy factors were the absence of: diagnosis (47.3%), consultation with and angiologist (63.5%), compressive treatment (100.0%), adequate optical therapy (98.62%), adequate dressing kit (70.3%), training for the changing of dressings (67.6%), following by the FHP team (51.4%) and performed exams (55.4%). We ve concluded that patients with VU mostly present now socioeconomical level and associated chronic diseases. Considering that assistance offered by FHP is non-systematic, fragmented, with no diagnosis planning, continual evaluation and evolution, we qualify the assistance as inadequate and with low level of solution, directly interfering on the maintenance of the VUs chronic state

Produção de matéria seca e absorção de nutrientes pelo milho em razão da saturação por bases e da adubação potássica

O trabalho foi conduzido em condições de casa de vegetação, com o objetivo de avaliar a resposta do milho à adubação potássica e à saturação do solo por bases, na produção de matéria seca e na absorção de nutrientes. O delineamento experimental foi inteiramente casualizado, com quatro repetições, em esquema fatorial 3x2x4, constituindo-se de três solos (Areia Quartzosa, Latossolo Vermelho-Escuro e Latossolo Roxo), dois valores de saturação por bases (40% e 70 %) e quatro teores de K no solo (0,5, 1,5, 3,0 e 6,0 mmol c dm-3). Para a calagem, foi utilizada mistura de carbonato de cálcio + carbonato de magnésio (PRNT = 103,3 %) na proporção de 4:1. A adubação básica constou de 200 mg kg-1 de N, 200 mg kg-1 de P e 5 mg kg-1 de Zn por vaso de 30 L, sendo o N parcelado em 2,48 g (83,7 mg kg-1) na semeadura e o restante em duas coberturas aos 25 e 40 dias após a emergência das plântulas (DAE). As doses de K utilizadas foram de 0, 3,62, 7,24 e 14,48 g de KCl por vaso. A semeadura foi realizada em 4/3/97, utilizando-se o milho cv. Zêneca 8392, mantendo-se uma planta/vaso durante 60 DAE. O K proporciona ganhos de matéria seca até teores de 1,5 mmol c dm-3 no solo. O aumento dos teores de K no solo resultam em queda na concentração de Ca e Mg na matéria seca do milho. A elevação da saturação por bases e respectivo aumento dos teores de Ca e Mg no solo reduzem a absorção de K pelo milho.

Adubação nitrogenada em cobertura e substratos na produção de mudas de mamoeiro 'Formosa'

Objetivando-se avaliar a produção de mudas de mamoeiro em diferentes substratos com adubações de nitrogênio em cobertura, conduziu-se um experimento em viveiro de formação de mudas no pomar da Universidade Federal de Lavras (UFLA), Minas Gerais. Foram testadas cinco doses de nitrogênio 0; 400; 800; 1600 e 3200 mg de N dm-3 de substrato, aplicados cinco vezes, sendo que em cada aplicação foram adicionados aos sacos de polietileno (capacidade de 500 mL) 20 mL de solução contendo o N e duas composições de substratos: A (composto orgânico + areia + solo na proporção de 1:1:3 em volume) e B (Plantmax® + areia + solo na proporção de 1:1:3 em volume). Foi utilizado o delineamento experimental em blocos ao acaso em esquema fatorial 5 x 2, com 4 repetições e cinco plantas por parcela. Após 150 dias da semeadura avaliaram-se as seguintes variáveis: comprimento da parte aérea (cm); comprimento de raiz (cm), número de folha/muda, matéria seca da parte aérea, da raiz e total (g/planta). Verificou-se que dosagem de até 1.800 mg de N dm-3 em cobertura, foram as que proporcionaram melhor qualidade na formação das mudas. em relação aos substratos verificou-se que o substrato B (Plantmax® + areia + solo na proporção de 1:1:3 em volume) foi o que promoveu os melhores resultados na produção das mudas do mamoeiro 'Formosa'.

Effects of age at slaughter and sire genotype on fatness, muscularity, and the quality of meat from ram lambs born to Romney ewes

Ram lambs (n = 356) born to Romney ewes and sired by a range of straightbred or crossbred sires were evaluated for carcass composition and, for a subsample (n = 236), some meat quality characteristics over a period of 4 years. Within each year, 2 to 4 sire genotypes, including Romney controls, were evaluated at 2 slaughter ages (5-9 months and 10-11 months). Weight-adjusted carcass length was greater for lambs with some East Friesian or Finn genes, but no differences were found in dressing-out percent. At a constant carcass weight, carcass fatness (fat depths and leg dissectible fat) was lower in lambs with East Friesian, Texel, or Finn genes. Meat yield at a constant weight tended to be greatest in sire groups that were least fat, and M:B ratio in the femur region was highest in lambs with Texel genes and, to a lesser extent, those with Poll Dorset genes. Leg muscularity in the femur region generally paralleled differences in M:B, except in a comparison of East Friesian-cross and Romney lambs where the former had lower muscularity but slightly better M:B. Lambs slaughtered at the older age for each year had longer and leaner carcasses at the same weight, possibly because they had been taken part way through a winter or because of slower growth rates leading up to slaughter. Meat quality characteristics differed little between the genotype groups, but for 2 of 3 years, meat from the semimembranosus muscle of lambs in the older slaughter lot was significantly tougher.

Desempenho e rendimento de carcaça de bovinos mestiços alimentados com diferentes volumosos e fontes protéicas

Quarenta bovinos machos, com 30 meses de idade e 371 kg, foram distribuídos em um delineamento em blocos casualizado com esquema fatorial 3 x 3, para avaliar o desempenho e rendimento de carcaça quando alimentados com diferentes fontes protéicas (Amiferm, uréia e farelo de soja) e volumosos (pastagem de capim-braquiária, cana-de-açúcar e silagem de milho). As dietas foram balanceadas para conterem níveis semelhantes de em e PB. A interação volumoso x fonte de N não foi significativa para nenhum dos parâmetros estudados. O ganho de peso vivo diário (GPV/dia) dos animais alimentados com cana-de-açúcar (0,83 kg) não diferiu dos mantidos em pastagem (0,82 kg), mas ambos foram menores que dos animais alimentados com silagem de milho (1,09 kg). As diferentes fontes de N proporcionaram GPV/dia semelhantes, com valores de 0,94; 0,83 e 0,97 kg, para os animais que receberam uréia, Amiferm e farelo de soja, respectivamente. As dietas contendo farelo de soja proporcionaram maior ganho de carcaça diário (0,57 kg) em relação ao uso de Amiferm, não diferindo da uréia (0,55 kg). Não houve diferença entre volumosos e fontes nitrogenadas para rendimento de carcaça, rendimento de carcaça do corpo vazio, rendimento de carcaça do ganho de peso e espessura de gordura, com média de 51,03%, 54,49%, 60,10% e 8,5 mm, respectivamente. O uso de Amiferm proporcionou ganhos de peso e rendimento de carcaça semelhantes às demais fontes protéicas.

Diferentes Perfis de Aminoácidos para Frangos de Corte no Período de 43 a 56 Dias de Idade

Um experimento foi conduzido para avaliar o desempenho e rendimento de carcaça de duas marcas comerciais de frangos de corte alimentados com diferentes perfis de aminoácidos. Dados de desempenho (ganho de peso, consumo de ração e conversão alimentar), carcaça (rendimento de carcaça, peito, pernas, dorso, asas, pés, cabeça e gordura abdominal) e vísceras comestíveis (moela, fígado e coração) foram coletados. O experimento foi realizado no período de 43 a 56 dias de idade e o delineamento experimental foi inteiramente casualizado em esquema fatorial 2x4 (duas marcas comerciais -- Hubbard e HI-Yield, e quatro perfis de aminoácidos - NRC (1994), Rostagno et al. (1992), Degussa (1997) e AEC (1993)), com quatro repetições de 50 aves cada. Quando as diferentes recomendações foram comparadas, o nível de lisina foi mantido constante, utilizando o nível do NRC (1994) como padrão. As aves alimentadas com dietas formuladas segundo recomendações do NRC (1994) apresentaram menor ganho de peso e pior conversão alimentar. As aves da marca comercial Hubbard apresentaram melhor ganho de peso, porém o consumo e a conversão alimentar não foram alterados. O rendimento de carcaça não diferiu entre os tratamentos. Contudo, as aves da marca comercial Hubbard apresentaram melhor rendimento de pernas e as aves HI-Yield, melhor rendimento de peito. A gordura abdominal foi afetada pelos tratamentos estudados em que aves da marca comercial Hubbard e alimentadas de acordo com os níveis recomendados pelo AEC (1993) apresentaram menor porcentagem de gordura abdominal. Não ocorreu efeito significativo para as vísceras comestíveis.

Influence of genetic type and level of concentrate in the finishing diet on carcass and meat quality traits in beef heifers

Carcass and meat quality traits of thirty-six feedlot beef heifers from different genetic groups (GG) fed at two concentrate levels (CL) were evaluated using 12- Nellore (NE), 12 - 1/2Angus x 1/2Nellore (AN) and 12 - 1/2Simmental x 1/2Nellore (SN) animals. Six heifers of each GG were randomly assigned into one of two treatments: concentrate at 0.8% or 1.2% of body weight (BW). Heifers fed concentrate at 0.8% of BW had greater (P<0.05) dressing percentage. None of the proximate analysis components of the beef were affected (P>0.05) by either CL or GG. Heifers from the AN group had higher (P<0.05) carcass weights, 12th rib fat thickness and lower dressing percentage (P<0.05) compared to the other groups. NE heifers had greater WBSF values (P<0.05) than the other genetic groups. Data suggest that the concentrate level can be reduced without compromising meat quality traits. (C) 2011 Elsevier Ltd.

Aspectos quantitativos de carcaças de bovinos de diferentes raças, alimentados com diferentes níveis de energia

Objetivou-se avaliar as características quantitativas da carcaça de bovinos machos não castrados, terminados em confinamento e abatidos aos 13-14 meses de idade. Foram utilizados 16 bezerros com nove meses de idade e peso médio inicial de 220 kg (oito Aberdeen Angus - AA e oito Hereford - HE), submetidos a dois níveis de energia (3,07 e 3,18 Mcal/kg de MS). O desenho experimental foi inteiramente casualizado, em arranjo fatorial 2 x 2 (duas raças e dois níveis de energia). O volumoso utilizado foi a silagem de milho, com 36% de grãos na matéria seca (MS). O concentrado nos tratamentos de menor nível de energia participou com 12% e naqueles de maior nível, com 32% da MS da dieta. Os animais foram abatidos quando, por estimativa, as carcaças apresentaram, na média, um mínimo de 190 kg. Os animais AA apresentaram maior rendimento de carcaça quente (54,95 contra 53,75%), maior comprimento de perna (64,12 contra 62,12 cm) e maior área do músculo Longissimus/100 kg de carcaça (29,31 contra 27,41 cm²). Os animais que receberam o maior nível de energia na dieta apresentaram maior comprimento de perna (71,75 contra 64,50 cm) e melhor conformação da carcaça (11,25 contra 10,12 pontos). Observou-se interação significativa entre raça e nível de energia para a espessura de gordura subcutânea, sendo a maior espessura verificada nas carcaças dos animais HE, que receberam o menor nível de energia.
