2. QUALIDADE DA CARCAÇA E CARNE DE NOVILHOS ALIMENTADOS COM DIETAS COM BORRA DE SOJA / CARCASS AND MEAT QUALITY OF STEERS FED DIETS WITH SOYBEAN SOAPSTOCK
The objective of this study was to evaluate carcass characteristics, the non carcass components, the lipid profile and the sensorial characteristics of meat from steers finished in feedlot fed diets containing different levels of inclusion of soybean soapstock. We used 30 Nellore and Charolais-Nellore crossbred steers with initial mean age of 20 months and i

4. Specific fatty acids as metabolic modulators in the dairy cow
This review summarizes recent developments on the utilization of specific fatty acids to modulate bovine energy metabolism, with emphasis on the periparturient dairy cow. A number of experiments have assessed the effects of polyunsaturated fatty acids on bovine hepatic energy metabolism using in vitro and in vivo models. Treatment of hepatocytes with specifi

5. Monensin e yeast on oil diets fed to Nellore finishing bulls / Monensina e levedura em dietas com óleo fornecidas a touros Nelores em terminação
This work had the objective of evaluate the use of monensin, yeast and the interaction of these additives on Nellore digestive metabolism and performance. It were conducted two trials. Experiment 1. It were utilized four Nellore steers with rumen and duodenum cannulas to evaluate the diet degradability, digestibility, biohydrogenation, rumen microrganisms an

6. Quantificação de ácidos graxos trans em alimentos consumidos pela população do DF
Este estudo investigou a composição de ácidos graxos de 11 alimentos fontes de AGT consumidos por indivíduos adultos moradores do Distrito Federal e a contribuição dos diferentes isômeros trans na composição destes alimentos. Avaliou também a variabilidade inter-produtos em relação ao conteúdo de AGT. Todos os alimentos apresentaram AGT, sendo o

7. Pofile of fat acids and digestion kinetic of nutritious in caprines / Perfil de ácidos graxos e cinética da digestão de nutrientes em caprinos
Objetivou-se com este estudo, avaliar o efeito do uso de fontes lipídicas apresentando diferentes graus de saturação de ácidos graxos (AG) sobre o consumo, a digestibilidade, o balanço de nitrogênio, o fluxo de nutrientes, a produção e a eficiência microbiana, as características ruminais, e o perfil de AG da digesta omasal (fluxo). Utilizou-se 8 ca

8. AVALIAÇÃO DE DIFERENTES SISTEMAS DE ALIMENTAÇÃO SOBRE AS CARACTERÍSTICAS QUE AFETAM A QUALIDADE DA CARCAÇA E DA CARNE / EVALUATION OF DIFFERENT FEEDING SYSTEM ON THE CHARACTERISTICS THAT AFFECT THE CARCASS AND MEAT QUALITY
This work was divided in two experiments. In first the objective was to evaluate the carcass, meat, carcass no integrants components and fatty acids profile of intramuscular fat of Devon steers finished in: feedlot (CONF), or winter pasture (pasture of ryegrass - Lolium multiflorum Lam -PTEM), or tropical pasture (association of millet pasture - Pennisetum a

9. The effect of conjugated linoleic acid supplementation on lipid profile and body composition of healthy growing wistar rats. / O efeito da suplementação com acido linoleico conjugado sobre o perfil lipidico e a composição corporal em ratos wistar saudaveis em crescimento.
Conjugated linoleic acid (CLA), a group of positional and geometric isomers of linoleic acid with conjugated double bonds, occurs in small quantities in a wide variety of foods. CLA can originate in the rumen by biohydrogenation of fatty acids from ingested food, and by the desaturation of the trans-11 C18:1 fatty acid. Thus, significant concentrations of CL

11. Effect of Linoleic Acid Concentration on Conjugated Linoleic Acid Production by Butyrivibrio fibrisolvens A38
Butyrivibrio fibrisolvens A38 inocula were inhibited by as little as 15 μM linoleic acid (LA), but growing cultures tolerated 10-fold more LA before growth was inhibited. Growing cultures did not produce significant amounts of cis-9, trans-11 conjugated linoleic acid (CLA) until the LA concentration was high enough to inhibit biohydrogenation, growth was in

12. Biotransformation of linoleic acid and bile acids by Eubacterium lentum.
Eubacterium lentum is a gram-positive, nonsporeforming, nonmotile, asaccharolytic anaerobe. In the present investigations, 3 E. lentum strains (group E) isolated from rat feces were compared with 30 E. lentum strains (groups A, B, C, and D) previously studied by Macdonald et al. (I. A. Macdonald, J. F. Jellet, D. E. Mahony, and L. V. Holdeman, Appl. Environ.
