Avanços metodológicos na avaliação da qualidade da forragem conservada

A avaliação correta do valor nutricional da forragem passa obrigatoriamente por emprego de metodologias adequadas. A qualidade da forragem depende dos produtos da fermentação, no caso da silagem, ou da magnitude das perdas de compostos solúveis e atuação de microrganismos no caso do feno. A abordagem do tema: Avanços metodológicos na avaliação da qualidade da forragem conservada, na 44ª Reunião Anual da Sociedade Brasileira de Zootecnia, tem como objetivo destacar as principais metodologias empregadas na avaliação específica de forragens conservadas, adicionais às avaliações tradicionais de composição químico-bromatológica desses volumosos, e colocar em discussão a necessidade de padronização de procedimentos analíticos. Assim, a revisão prioriza a descrição e sistematização de métodos físicos e químicos importantes para serem implementados na avaliação de forragens conservadas, na tentativa de homogeneizar tais procedimentos. Os recursos metodológicos disponíveis atualmente permitem não somente quantificar, mas também qualificar perdas ocorridas no processo de conservação, exposição aeróbia e oferta dos volumosos aos animais. Esse fato sugere que a adoção de estratégias de manejo dessas forragens deverá, preferencialmente, ser acompanhada de avaliação de perdas integradas no processo.

Qualidade e composição química da carne de bovinos de corte inteiros ou castrados de diferentes grupos genéticos Charolês x Nelore

Seventy beef males of three breeding systems (BS), straightbreds Charolais (Ch) and Nellore (Ne), G1 crossbreds: 1/2 Ch + 1/2 Ne (1/2 Ch) and 1/2 Ne + 1/2 Ch (1/2 Ne) and G2 crossbreds: 3/4 Ch + 1/4 Ne (3/4 Ch) and 3/4 Ne + 1/4 Ch (3/4 Ne) were used. The number of animals by genetic group was, respectively, 15, 12,8, 12,14 and 9. Thirty-five males were castrated (C) at seven months and 35 were kept intact (1). The animals were feedlot finished from 20 to 24 months. The longissimus dorsi muscle was used for the meat evaluation. No significant interaction was observed between genetic composition and sexual condition, for the variables studied. The I males displayed meat with darker color (3.05 vs. 3.78 points) with less amount of marbling (4.26 vs. 5.75 points) and less amount of ether extract (1.73 vs. 2.88%). However they presented larger (66.03 vs. 60.50 cm(2)) longissimus dorsi area and meat with better palatability, juiciness and tenderness. Ch animals had larger longissimus dorsi than the Ne. In the G I group, the 1/2 Ch meat showed larger amount of marbling and ether extract and less cooking losses than the 1/2 Ne meat. Between G2 animals, the 3/4 Ne showed meat with larger thawing losses and larger amount of ether extract. In G1 animals meat, the heterosis level reached 18.54% for longissimus dorsiarea, 28.10% for ether extract and 64.01% for amount of marbling. In G2, the heterosis was -17.30% for lean texture and 10.40% for longissimus dorsi area.

Thirty 3/4 Canchim + 1/4 Nelore young bulls with 417 kg of body weight and 15 months of age, were confined during 84 days. The animals were fed with diets composed with corn silage, corn grain, cottonseed meal, soybean meal, whole soybean and mineral mix, adjusted in agreement with the recommendations of the Metabolizable Protein System (MP), Cornell Net Carbohydrate and Protein System (CNCPS) and Intestine Digestible Protein System (PDI), for predicted body weight gain of 1.3 kg/head/day. The daily body weight gain did not differ among treatments CNCPS, MP and PDI, with 1.51; 1.48; and 1.13 kg/head, respectively. The economic analysis revealed net profit of R$116.25; R$148.30; and R$108.51/head for CNCPS, MP and PDI systems, respectively. The diets adjusted by CNCPS and MP systems provided superior animal performance than that expected, while the diet adjusted by PDI system did not allow the predicted body weight gain.

Three pig genetics lineages A, B and C marketed in Brazil, were stunning with the manual electric stunning (Karl Schermer 220-230/250 volts, 45-60 Hz and 1.4 - 1.5 A) and the collective gaseous system (COMBI-BUTINA 90% CO 2). The electric stunning provided higher blood splashed levels in the areas of the inside round (0.477 and 0.26, p ≤ 0.01), shoulder/cranial (0.154 and 0.039, p ≤ 0.005), shoulder/central (0.261 e 0.052, p ≤ 0.001), shoulder/caudal (0.180 and 0.030, p ≤ 0.01), loin/central (0.185 and 0.065, p ≤ 0.01), loin/caudal (0.06 and 0.207, p ≤ 0.01) and loin/lateral external (0.061 and 0.013, p ≤ 0.05), as well as more diffuse blood splashed in the areas of the inside round (0.461 and 0.279, p ≤ 0.05), shoulder/cranial (0.154 and 0.039, p ≤ 0.001), shoulder/central (0.231 and 0.039, p ≤ 0.001) and shoulder/caudal (0.185 and 0.026, p ≤ 0.001). The electric stunning also provided higher skin damage levels in the areas of the shoulder (1.098 and 0.795, p ≤ 0.001), body (1.04 and 0.948, p ≤ 0.05) and ham (0.84 and 0.68, p ≤ 0.001), as well as higher eyelid reflex levels (11.57%) comparatively to the gaseous system (2.86%) of a total of 426 pigs. Small indexes of bone fractures and muscle bruises were found in both systems.

Avaliação de genótipos de soja em semeadura de inverno, em Selvíria, MS: Produção e qualidade fisiológica de sementes

The sowing of soybean out of the conventional period is an option for the production of seeds with high physiological quality. On the other hand, this fact makes necessary the search for cultivars adapted to new environmental conditions. Therefore, additional research is needed to supply more information to producers related to the choice of the most suited cultivars with regard to high seed quality. This research was conducted in Selvíria, MS, Brazil in which the cultivars FT-2000, FT-Inaê, Embrapa 20 (Doko RC), CAC-1, IAC-17, IAC-18, IAC-19, IAC-8-2, FT-101, FT-109, MT/ BR 45 (Paiaguás), MT/BR 50 (Parecis), MT/BR 52 (Curió), MT/BR 53 (Tucano), MT/BR 47 (Canário), MT/BR 49 (Pioneira), BRSMT Uirapuru, BR Emgopa 314 (Garça Branca), MG/BR 46 (Conquista), FT-Estrela, FT-Cometa, Dourados, JAB-11, BR 9 (Savana), FT-Abyara, Embrapa 30 (Vale do Rio Doce), Embrapa 9 (Bays), Embrapa 31 (Mina), IAC-16; IAS 5, EMGOPA-304, and IAC-Foscarin 31 were studied. These cultivars were sown on June 5, 1998, and evaluated both for agronomic characteristics and the physiological potential of the seeds. The experimental units were arranged in the field according to a randomized complete block design with five replicates. The cultivars more adapted to the climatic conditions were Parecis, Bays, CAC-1, Garça Branca, Paiaguás, Pioneira, and IAC-16. It was concluded that winter sowing should start at the beginning of May, with water supply, since June was found to be too late.

Avaliação de interpoladores estatísticos e determinísticos na estimativa de atributos do solo em agricultura de precisão

The obtaining of the correct space distribution for attributes of the soil is relevant in the agricultural planning, in what concerns to the installation and maintenance of the cultures. The objective of that work was to compare statistical interpolation methods (ordinary krigagem) and deterministic methods (inverse square distance) in the estimate of CTC and V% in a distrophic yellow-red Latossolo. The study was accomplished in the State of Experimental Hands on of the Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural (INCAPER), in an irregular grading with 109 points. The data were collected in the layer of 0 - 0,20 m in the projection of the cup of the plants, in the superior part of the slope. The performance of the interpolators was obtained and compared using the criterion of the medium mistake. The observations are dependent in space until a maximum reach of 14,1 m, considering the isotropy. IDW presented larger mistake in the estimate of the data; however its difference in relation to KRIG was small for both variables.

Testes de vigor para avaliação da qualidade fisiológica de sementesde Sebastiania commersoniana (Baill.) Smith & Downs.

The objective of this work was to evaluate the efficiency of different vigor tests to assess S. commersoniana seeds physiological quality during storage. Therefore, seeds were stored in cloth bags, plastic bags and glass containers for 531 days, both at room temperature and in a cold chamber. Periodically samples were taken and the following tests were conducted: standard germination, germination speed index, first count after germination, seedlings fresh and dry matter, electrical conductivity (imbibitions for 2 and 24 hours) and accelerated aging, in order to monitoring the seeds physiologic quality. Data were submitted to polynomial regression analysis, for each of the combination of packaging/storage condition. The results obtained led to the following considerations: a) the speed germination index and the accelerated aging test permitted a good evaluation of the seed-lots quality; b) the first count of germination did not allow any prediction about seed lots vigor; c) seedling fresh and dry matter did not discriminate among seed lots; d) electrical conductivity test after 2 h imbibitions was not adequate to evaluate the seed lots vigor and e) the electric conductivity test with 24 h imbibitions was more adequate to differentiate among seed lots, but with little efficiency to discriminate among seed lots with intermediate vigor or with low quality differences.

A ótica do usuário na avaliação da qualidade do programa de atenção odontológica à gestante

Objective: To evaluate the pregnant women's perception of the FOA-UNESP's Pregnant Women Dental Care Program (Araraquara, SP, Brazil). Method: The sample included 75 pregnant women and used a questionnaire with 16 closed questions, containing variables grouped in the following categories: the didactic-psychological meetings, clinical treatment, professional's profile, clinical facility, fear/confidence in the treatment, and learning. Except for the variables fear/confidence in the treatment and learning, to which 'yes' or 'no' answers were attributed, the remaining variables were attributed answers varying from weak to excellent. The questionnaire pretested in a pilot-study and applied after informed consent was obtained from all pregnant women treated between 2005 and 2006. Results: Most women rated as excellent the information addressed during the didactic-psychological meetings (81.1%), the clinical treatment (90.6%), the professional as to personal appearance, kindness and attention (88.7%, 96.2% and 90.6%, respectively), and the clinical facility as to cleanness, ventilation and comfort (92.5%, 86.8% and 90.6%, respectively). Most of them stated to feel confident (96.2%) and have no fear (86.8%) during the treatment and also affirmed having learned new information in the didactic-psychological meetings of the program (92.5%). Conclusion: The services and actions developed in the program have reached successful outcomes, providing health to the pregnant women and their forthcoming babies.

Qualidade de salsichas elaboradas com carne mecanicamente separada de tilápias do nilo e armazenadas sob refrigeração

Filleting yield of Nile tilapia Oreochromis niloticus (L.) is low (30%) and generates large amount of wastes that may turn into environmental and economic problem. However, these wastes can be used for the extraction of minced fish (MF) which can be used in the preparation of sausages. The objective of this study was to assess the quality of sausages prepared with 0, 20, 40, 60, 80 and 100% of MF from Nile tilapia filleting waste during storage at 0±0.3°C. Alterations in the instrumental color (L*, a* and b*), lipid oxidation (TBARS), total volatile nitrogenous bases (TVB-N), pH, microbiological condition (pathogenic bacteria and aerobic psychrotrophic bacteria), and sensory attributes (color, odor, flavor, texture and overall acceptability) were evaluated for up to 40 days. The addition of MF to sausages increased TBARS values and decreases TVB- N, L*, a* and b* values. Acceptability of color attribute decreased with increasing MF; best flavor, texture and overall acceptability scores were registered for sausages containing 40 and 60% MF; best odor was registered for 100% MF. Pathogenic microorganisms were not detected, but decrease in pH and proliferation of aerobic psychrotrophic bacteria which, however, did not compromise sensory evaluation of sausages were registered throughout storage. Sausages prepared with MF from tilapia filleting waste have a shelf-life of 40 days when stored at 0±0.3°C, and the maximum recommended MF inclusion to maintain good sensory quality is 60%.

Qualidade fisiológica de sementes de Brachiaria e avaliação da produtividade de massa seca em diferentes sistemas de integração lavoura-pecuária sob irrigação

The speed and magnitude of tropical pastures expansion in Brazil are related to the availability of quality seeds. This research aimed to evaluate the physiological quality of seeds of two Brachiaria species submitted to germination and viability tests and also estimate, for both species, the fresh and dry mass yield, under different irrigated crop-livestock integration systems. For field analysis, the experimental design was a randomized complete block, in subplots, with four intercrops in the plot (Brachiaria brizantha cv. Marandu and Brachiaria ruziziensis simultaneously established with corn and nitrogen fertilization coverage), and four forage cutting times, in the winter/spring season, in subplots, with four replications. In the laboratory, the experimental design was completely randomized, with four replications per treatment/test. The germination and viability tests indicated that B. brizantha seeds showed higher physiological quality, when compared with B. ruziziensis, while the tetrazolium test and germinated seedlings characteristics were similar. The B. ruziziensis, simultaneously intercropped with corn, was the less viable intercrop, due to the lower fresh and dry mass yield and litter deposition on the soil surface. In general, the pasture formation for the second season cultivation, intercropped with corn, was an excellent alternative for crop-livestock integration under a no-tillage system.

Avaliação da qualidade da água purificada em farmácias magistrais da região de São José do Rio Preto, SP

Water is the raw material used most in the production of diverse pharmaceutical forms and, being a constituent of the formulation itself, is subject to a number of physico-chemical and microbiological specifications. In addition, it is indispensable for laboratory tests and the cleaning of equipment and apparatus. The aim of this study was to ascertain the degree of physicochemical and microbiological contamination of purified water used in compounding pharmacies in the city of São José do Rio Preto, SP, Brazil. Samples were taken as recommended in the USP Pharmacopeia, with careful aseptic technique, and sent immediately the to quality control laboratory. Physicochemical properties were analyzed, including appearance, pH, conductivity, residue after evaporation, ammonia, calcium, chloride, heavy metals, sulfate and oxidizable substances, and microbiological tests were performed: total aerobic microbial count and detection of total and thermotolerant coliforms and Pseudomonas aeruginosa. Results showed that some parameters did not conform to the standards, especially pH, conductivity, inorganic impurities, oxidizable substances and microbiological test data, in 10%, 17%, 10%, 14% and 20% of the analyzed samples, respectively, This points to the need for greater care in the production and/or storage of purified water in these pharmaceutical establishments.
