The aim of this study was to evaluate the effect of fat supplementation for enhancing milk conjugated linoleic acid (CLA) in early lactation without affecting ruminal fermentation. 24 Holstein dairy cows were assigned to a completely randomized design employing a 2 × 4 factorial arrangement. Factors were particle size (15 and 25 mm) and two different sources of alfalfa supplemented with and wit...

background: studies have shown that zinc and selenium deficiency is common in nonalcoholic fatty liver disease (nafld). however, the effects of zinc and selenium co-supplementation before and/or after disease progression on nafld are not clear enough. the aim of this study was to compare the effects of zinc and selenium co-supplementation before and/or after disease progression on nafld prognos...

conclusions the study demonstrated that 1000 iu vitamin d supplementation for 3 months can decrease the insulin resistance in individuals with prediabetes; however, it has no significant effect on body fat mass percentage. background low serum levels of vitamin d are supposed to contribute to the incidence of diabetes; therefore, vitamin d supplementation may reduce the incidence of diabetes in...

. eight holstein cows in early lactating stage were used in a 4×4 change-over design within 4 periods of 21-d to determine the effects of alfalfa hay particle size and soybean oil supplementation on intake, digestibility, ruminal and blood metabolites, chewing activity, milk yield and compositions. four total mixed rations containing 20, 20 and 60% corn silage, alfalfa hay and concentrate respe...

Six crossbred steers (315 kg) with cannulas in the rumen, proximal duodenum and distal ileum were used to study the influence of level and source of dietary fat on characteristics of digestion. Dietary treatments consisted of a steam-rolled barley-based finishing diet containing 1) no supplemental fat; 2) 4% yellow grease (YG); 3) 4% blended animal-vegetable fat (BVF); 4)8% YG; 5) 8% BVF or 6) ...

Several studies showed that l-leucine supplementation reduces adiposity when provided before the onset of obesity. We studied rats that were exposed to a high-fat diet (HFD) for 10 weeks before they started to receive l-leucine supplementation. Fat mass was increased in l-leucine-supplemented rats consuming the HFD. Accordingly, l-leucine produced a hypothalamic pattern of gene expression that ...
