13. Evaluation of blood metabolites in dairy cows grazing under two pasture allowances and supplemented with corn silage under restricted grazing conditions
ABSTRACT This study was conducted to evaluate the influence of management tools - daily pasture allowance and corn silage supplementation - during periods of forage shortage on the metabolism of dairy cows grazing low-mass pasture in temperate regions. Forty lactating Holstein cows were used during an experimental period of seventy days (April 15 to June 23,

14. Supplementation with a mixture of whole rice bran and crude glycerin on metabolic responses and performance of primiparous beef cows
ABSTRACT - This study investigated the effect of a supplement containing whole rice bran and crude glycerin for 21 days before mating on metabolic, productive, and reproductive responses of 28 primiparous suckling beef cows. Cows were randomly assigned to a control group (CON, n = 14), grazing on grasslands, and a supplemented group (SUP, n = 14), grazing on

15. Changes in maternal body composition and metabolism of dairy goats during pregnancy
The objective of this study was to evaluate the mobilization of nutrients in goats of different gestation types and pregnancy stages. Forty-four Saanen and Oberhasli goats were studied. The goats of each breed and gestation type (single or twin) were slaughtered at different gestational ages (80, 110, and 140 days of pregnancy), forming a completely randomiz

16. Effect of CLA supplementation to low-protein diets on the growth performance, carcass characteristics, plasma urea nitrogen concentration, and fatty acid profile in the meat of pigs
To analyze the effect of conjugated linoleic acid (CLA) on the meat of pigs (0,1%) and three crude protein (CP) levels (nursery: 20.5, 16.0, 14.5%; growing: 16, 14.5, 11.5%; and finishing: 14.0, 12.5, 11% CP), studies were conducted with 36 hybrid (Yorkshire×Landrace×Duroc) barrows (17.3-83.5 kg), which were individually penned and allotted in a completely

17. Production, Composition, Fatty Acids Profile and Stability of Milk and Blood Composition of Dairy Cows Fed High Polyunsaturated Fatty Acids Diets and Sticky Coffee Hull
Four lactating Holstein cows were assigned to a 4 × 4 Latin square design to determine the effects of feeding sticky coffee hull (SCH) as a source of antioxidants on dairy cows fed with high PUFA diets. The treatments (on DM basis) were control diet, diet with 30 g/kg of soybean oil, diet with 30 g/kg of soybean oil and 100 g/kg of SCH, and diet with 30 g/k

18. Nitro-fatty acids: novel anti-inflammatory lipid mediators
Nitro-fatty acids are formed and detected in human plasma, cell membranes, and tissue, modulating metabolic as well as inflammatory signaling pathways. Here we discuss the mechanisms of nitro-fatty acid formation as well as their key chemical and biochemical properties. The electrophilic properties of nitro-fatty acids to activate anti-inflammatory signaling

19. Efeito dos ácidos graxos saturados, poli-insaturados e trans no desenvolvimento de aterosclerose e esteatose hepática em camundongos com ablação gênica do receptor de LDL / Effect of saturated, polyunsaturated and trans fatty acids on the development of atherosclerosis and hepatic steatosis of mice with ablation of the LDL receptor gene
Introduction: The amount and type of dietary fat play important roles on the development of cardiovascular disease (CVD) and on the development of hepatic steatosis. Saturated (SAT) and trans (TRANS) fatty acids are known as pro-atherogenic, while the polyunsaturated (POLY) fats seem to exert an antiatherogenic action. Regarding hepatic steatosis, it is know

20. Programa de intervenção interdisciplinar em hábitos de vida em indivíduos de risco cardiometabólico: análise de fatores dietéticos associados à melhora do metabolismo glicídico / Interdisciplinary intervention program on lifestyle in individuals at cardiometabolic risk: analysis of dietary factors associated with improvement in glucose metabolism
Introduction: Cardiometabolic diseases are global public health problems with social and economic repercussions. Unhealthy diet is seen as one of the main modifiable risk factors, being of central importance for the prevention of these diseases. Despite the evidence that certain nutrients are associated with diseases, causal relationships are still under dis

21. Silagem de colostro: caracterização do perfil de fermentação anaeróbia e desempenho de bezerros leiteiros / Colostrum silage: dynamics of anaerobic fermentation and dairy calves performance evaluation
The objective of this study was to characterize the fermentative dynamic of bovine colostrum, under anaerobic condition, and determine the nutritional value, as well as evaluate dairy calves´ performance receiving colostrum silage as liquid diet. In the first experiment, bovine colostrum from second and third milking was fermented at room temperature in PET

22. Desempenho de vacas leiteiras suplementadas com sal de cálcio rico em ácido linoléico ou grão de soja tostado
Avaliou-se a suplementação de vacas leiteiras com 1,4% da matéria seca da dieta de extrato etéreo oriundo de sal de cálcio rico em ácido linoléico (SCa) ou soja tostada grosseiramete moída (ST). Vinte e quatro vacas da raça holandesa receberam estes tratamentos e o Controle (C) em oito Quadrados Latinos 3x3, com períodos de 28 dias. A produção di

23. Lipidograma e glicemia de búfalos leiteiros criados no Estado de São Paulo: influência de fatores fisiológicos e valores de referência / Lipid and glucose profile of dairy buffaloes raised in São Paulo state: influence of physiological factors and reference values
The aim of this study was to analyze the influence of age, gender, pregnancy, puerperium, lactation and breeding systems in the constituents of lipid metabolism and glucose of buffaloes. The biochemical analysis was obtained by determining the levels of serum cholesterol, triglycerides, beta-hydroxybutyrate (ß-HBO), non-esterified fatty acids (NEFA) and pla

24. Sobrecarga de ferro em ratos sadios / Iron overload in healthy rats
O objetivo do presente trabalho foi investigar o efeito de diferentes concentrações dietéticas de Fe em parâmetros sangüíneos (hemograma, perfil lipídico) e hepáticos (concentração de minerais, perfil de ácidos graxos, apoptose) de ratos sadios. Depósitos de Fe no baço e medula óssea também foram avaliados por análises histológicas. Ratos Wi
