Influence of different fat sources on the performance, egg quality, and lipid profile of egg yolks of commercial layers in the second laying cycle

This study was designed to evaluate the effects of different fat sources on the performance, egg quality, and lipid profile of the egg yolks of layers in their second production cycle. The fat sources were cottonseed oil, soybean oil, lard, sunflower oil, or canola oil. Experimental diets were fed to postmolt ISA Brown layers at 70 wk of age and the experimental period was 74 to 86 wk of age. The different fat sources did not influence performance or eggshell quality, but lipid profile of the egg yolk changed as a function of dietary fat sources. In general, the best changes, such as lower level of saturated fatty acids, higher levels of alpha-linolenic acid and DHA, and lower linoleic acid levels, were promoted by the addition of canola oil, but it did not promote enrichment of the eggs with polyunsaturated fatty acids.

Fermentative and microbiological profile of marandu-grass ensiled with citrus pulp pellets

Forragens com alta umidade e baixa concentração de carboidratos solúveis, como é o caso dos capins tropicais, podem conduzir a condições desfavoráveis para a produção de silagens de qualidade satisfatória. Esse estudo objetivou conhecer o perfil fermentativo e microbiológico de silagens de capim-Marandu [Brachiaria brizantha (Hochst ex. A. Rich) Stapf cv. Marandu], colhido com 58 dias de crescimento, aditivadas com polpa cítrica peletizada (PCP),. Foram utilizados silos experimentais de PVC adaptados com válvula do tipo Bunsen, tendo a silagem atingindo densidade de 900 kg m-3. Os tratamentos foram constituídos por três proporções de PCP (0, 50 e 100 g kg-1 em relação a matéria natural) e sete tempos de abertura após a ensilagem (1, 4, 7, 14, 21, 28 e 56 dias). A presença de PCP aumentou os teores de CHOs em 15 a 20%, reduziu o pH (5,3 para 4,2) e diminuiu as concentrações de N-NH3. Houve crescimento da população de enterobactérias somente durante o primeiro dia de fermentação (média 3 UFC g-1), pequeno desenvolvimento de clostrideos (média 0,5 UFC g-1) e dominância de bactérias homo em relação às heterofermentativas, para os três tratamentos estudados. A adição de polpa cítrica durante a ensilagem do capim-Marandu foi benéfica, podendo ser recomendada desde que haja benefício econômico na sua adoção.

Socioeconomic and demographic profile of leprosy carriers attended in nursing consultations

A hanseníase é doença infecto-contagiosa para a qual, além das condições individuais, outros fatores relacionados aos níveis de endemia e às condições socioeconômicas desfavoráveis influem no risco de adoecer. Objetivou-se reconhecer o perfil socioeconômico e demográfico e o grau de incapacidade instalado dos portadores de hanseníase, atendidos no Centro de Saúde Escola de Botucatu, São Paulo, Brasil. Fizeram parte do estudo 37 pacientes. Os dados foram obtidos por meio do instrumento de consulta de enfermagem. Os resultados mostraram predominância de indivíduos com união estável (78%), brancos (92%), com idade entre 30 e 49 anos (51%), com baixo nível de escolaridade e com renda familiar per capita menor que um salário mínimo. Mais de um terço dos pacientes investigados (35%) apresentavam algum grau de incapacidade física. A associação do baixo perfil socioeconômico com a presença de incapacidades físicas imprime maior vulnerabilidade a essa população, podendo impactar negativamente a sua qualidade de vida.

Metabolic Profile of Offspring from Diabetic Wistar Rats Treated with Mentha piperita (Peppermint)

This study aimed at evaluating glycemia and lipid profile of offspring from diabetic Wistar rats treated with Mentha piperita (peppermint) juice. Male offspring from nondiabetic dams (control group: 10 animals treated with water and 10 treated with peppermint juice) and from dams with streptozotocin-induced severe diabetes (diabetic group: 10 animals treated with water and 10 treated with peppermint juice) were used. They were treated during 30 days, and, after the treatment period, levels of glycemia, triglycerides, total cholesterol, and fractions were analyzed in the adult phase. The offspring from diabetic dams treated with peppermint showed significantly reduced levels of glucose, cholesterol, LDL-c, and triglycerides and significant increase in HDL-c levels. The use of the M. piperita juice has potential as culturally appropriate strategy to aid in the prevention of DM, dyslipidemia, and its complications.

Evaluation of Glycemic and Lipid Profile of Offspring of Diabetic Wistar Rats Treated with Malpighia emarginata Juice

Knowing that maternal diabetes is related to hyperglycemia and fetal hyperinsulinemia, which affect the lipid metabolism, the aim of this study was to evaluate the effects of Malpighia emarginata (acerola) juice on the glycemic and lipid profile of offspring of diabetic and nondiabetic Wistar rats. The adult offspring of non-diabetic dams and of dams with severe streptozotocin-induced diabetes were divided into groups: G1, offspring (of control dams) treated with water, G2, offspring (of diabetic dams) treated with water, G3, male offspring (of control dams) treated with acerola juice, and G4, male offspring (of diabetic dams) treated with acerola juice. The offspring of diabetic dams treated with acerola juice showed significantly decreased levels of glucose, cholesterol, triglycerides, and increased HDL-c. The use of acerola juice is a potential strategy to aid in the prevention of DM and dyslipidemia and its complications or to act as an auxiliary in the treatment of these diseases.

Serological profile of Toxoplasma gondii and Neospora caninum infection in commercial sheep from São Paulo State, Brazil

Neosporosis and toxoplasmosis are two important infections in young and adult sheep, leading to low production and abortion. This study aimed to determine the frequency of antibodies to Toxoplasma gondii and Neospora caninum in sheep from the eastern region of São Paulo State, Brazil. Serum samples (382) were collected from the sheep and assayed for T. gondii through modified agglutination test (MAT) and indirect fluorescent antibody test (IFAT), and for N. caninum antibodies, through IFAT, with cut-off titers equal to 16 (T. gondii) and 25 (N. caninum). All frozen samples were sent to the Center for Zoonoses Research (NUPEZO), Department of Veterinary Hygiene and Public Health (DHSVP), FMVZ, UNESP, for serological tests. A total of 71/382(18.6%) samples reacted to T. gondii, especially at titers 16 (28; 39.4%), 64(15; 21.1%), 256 (21; 29.6%) and 1024 (6; 8.5%) by MAT, and 16(34: 47.9%), 64 (18; 25.4%), 256 (14; 19.7%) and 1024 (5; 7%) by IFAT. As regards N. caninum, 49/382 (12.8%) samples reacted at titers 25 (17; 34.7%), 50 (11; 22.5%), 100 (11; 22.5%), and >= 200 (10; 20.4%). These animals presented infection but no clinical signs. Six and ten animals had high titers for toxoplasmosis and neosporosis. No significant association was observed between antibodies for both parasites (P = 0.535) according to Fisher's exact test, and no correlation was found between T. gondii (MAT) and N. caninum antibody titers (r = -0.0068; P=0.895), T. gondii (IFAT) and N. caninum antibody titers (r = -0.0025; P = 0.961). Thus, T. gondii and N. caninum infections were observed in farms located in São Paulo State, where sheep play an important economical role for the national and regional business.
