Effect of Aflatoxin B1 on In Vitro Digestibility and Ruminal Fermentation of Sheep Diet
The aim of this study was to investigate the effect of different levels of aflatoxin on the gas production, in vitro fermentation parameters, dry matter and organic matter digestibility of sheep's diet. This experiment was conducted in a completely randomized design with 5 treatments and 4 replicate per treatment. The treatments included 1.diet without aflatoxin and methanol (control), 2.c...
متن کاملThe Effect of Soybean Meal Heating Time on the in vitro Digestibility and Ruminal Fermentation Profile
The aim of this study was to determine the most optimal heating time in protection of protein rich feedstuff on digestibility and in vitro ruminal fermentation profile. Proteinous feedstuffs used in this study is soybean meal (Glycine max). This study is designed using one way ANOVA, with five treatments of heating time (T0 (control)= unheated, T1= 10 min, T2= 20 min, T3= 30 m...
متن کاملEffects of pH and fermentative substrate on ruminal metabolism of fatty acids during short-term in vitro incubation.
The ruminal biohydrogenation of c9,c12-18:2 can be affected by the fibre/starch ratio of the diet and the ruminal pH. The objectives of this study were to examine independently in vitro the effects of fermentation substrate (hay vs. corn starch) and buffer pH (6 vs. 7) on the biohydrogenation of c9,c12-18:2 carried out by grape seed oil, focusing on its t11 and t10 pathways, using 6-h ruminal i...
متن کاملEffects of Linseed Lipid on Ruminal Fatty Acid Metabolism, Nutrient Digestibility, Milk Fatty Acid Composition, and Methane Emission in Ruminants
Linseed lipid in the dietary composition is a major factor influencing the fatty acid composition of milk from ruminants, because fatty acids which reach the duodenum are, at least in part, of dietary origin as well as the result of ruminal microbial biohydrogenation of dietary lipids. In this review, the effect of linseed lipid on ruminal fatty acid metabolism, nutrient digestibility, microbia...
متن کاملEffects of fiber source on apparent digestibility and ruminal fermentation parameters in sheep fed high-concentrate diets
Sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). Diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, T1), 35% wheat straw (T2), 35% barley straw (T3) or 35% maize straw (T4). Total-tract apparent digestibility for dry matter, organic matter...
متن کاملEffects of a bacterial probiotic on ruminal pH and volatile fatty acids during subacute ruminal acidosis (SARA) in cattle
Effects of a bacterial probiotic (BP) on ruminal fermentation and plasma metabolites were evaluated in four Holstein cattle (body weight, 645 ± 62 kg; mean ± SD) with induced subacute ruminal acidosis (SARA). SARA was induced by feeding a SARA-inducing diet, and thereafter, 20, 50 or 100 g per head of a commercial BP was administered for 7 consecutive days during the morning feeding. Cattle wit...
