15. Perfil metabólico de vacas Holandês e mestiças Holandês x Jersey no periparto
RESUMO O objetivo do presente trabalho foi determinar e comparar o perfil metabólico de vacas Holandês (H) e mestiças Holandês x Jersey (HxJ) no periparto. Avaliaram-se 24 vacas, sendo 11 vacas Holandês e 13 mestiças Holandês x Jersey. Semanalmente, coletou-se sangue para a determinação das concentrações séricas de glicose, beta-hidroxibutirato (

18. Effect of the addition of protected fat from palm oil to the diet of dairy sheep
ABSTRACT The objective of this study was to evaluate the effect of protected fat from palm oil on body weight and milk production and composition of lactating Lacaune ewes. Four treatments (0, 20, 40, and 60 g kg−1 as fed) of protected fat from palm oil were used to feed nine animals in each group. Isoproteic and isoenergetic diets were formulated and adju

21. Genetic parameters for type score traits and milk production in Brazilian Jersey herds
ABSTRACT This study aimed to estimate the heritability coefficients for ten functional type traits and milk production in the Jersey breed in Brazil, besides the genetic and phenotypic correlations between them. The present study utilised data from 1,567 records of linear type traits, including stature (ST), body depth (BD), loin strength (LS), rump width (R

22. Treatment with Ilex paraguariensis (yerba mate) aqueous solution prevents hepatic redox imbalance, elevated triglycerides, and microsteatosis in overweight adult rats that were precociously weaned
Early weaning (EW) leads to overweight, visceral obesity, hyperleptinemia, and insulin resistance in adulthood. Treatment with Ilex paraguariensis (yerba mate) improves obesity and insulin resistance in these animals. Here, we evaluated the effects of chronic treatment with yerba mate on the redox balance and liver morphology of overweight early-weaned rats.

24. Glycemic control in minks with tendency to obesity in the perinatal period with the use of HbA1C
ABSTRACT The objective of this study was to investigate the usefulness of HbA1C as a test in monitoring the long-term glycemic control during the perinatal period in minks with the tendency to obesity. On the scanbrown mink farm, screening research on one-year-old females showing predilections to obesity was conducted. In the first year of the experiment, 12
