Two completely random digestion trials were conducted, each with 12 beef steers (325 kg initial weight), to measure changes in digestibilities of fat and of forage components when fat was added to diets containing 62 to 76% wheat straw. Trial 1 diets contained either no added fat or 6.3% added fat from whole cottonseed (30% of the diet), cottonseed oil or animal fat; diets were formulated to co...
Four barrows of approximately 40 kg initial body weight, fitted with post-valvular T-cecum cannulas, were used to study the effect of lecithin as an external emulsifier on apparent ileal and overall digestibility of crude fat, fatty acids, and other dietary nutrients (DM, N, GE, crude fiber [CF], P, Ca, and Mg), as well as the utilization of N, GE, Ca, P, and Mg. Two levels of lecithin (0 and ....
The aim of this study was to evaluate the in vitro effect of coating soybean meal and canola meal with different fat sources on ruminal degradability and intestinal digestibility, as well as, the in vivo digestibility. For this purpose, calcium salt of omega-3, calcium salts of unsaturated fatty acids and prilled fat were used for coating. To determine ruminal degradability, three lactating Hol...
. 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...
The effects of non-starch polysaccharide (NSP) content of wheat and xylanase supplementation (XS) of the diet, on intestinal enzyme activity (amylase, aminopeptidase and lipase), fat digestibility and ileal viscosity of laying hens has been studied. Two hundred forty Hy-Line W-36 layer from 20 to 25 week of age were studied under a factorial experiment (4×2) in completely randomized design with...
This study was conducted with broilers to evaluate the effects of growth-promoting antibiotic (flavomycin) and probiotic (7 bacterial species) supplementation in diets containing soybean oil or free fatty acids (FFA) on performance, morphological parameters of the small intestine, apparent digestibility of gross energy (GE) in the ileum, and apparent digestibility of fat in the ileum and total ...
in order to study the effect of different levels of desiccated ox bile (dob; 0.00, 0.25, and 0.50%) and organic acid (oa; 0.00, 0.15, and 0.30% of the diet) on performance, fat digestibility, blood metabolites and ileal digesta viscosity in broiler chickens fed diets containing 5% tallow, in a completely randomized design with a 3×3 factorial arrangement and 4 replicates in each treatment, 360 ...
We investigated the effects of various dietary fibers or their likenesses on the apparent fat digestibility by rats fed on a high-fat diet. Each of 23 different fibers was added at 5% (w/w) to a purified diet containing 20% (w/w) corn oil. The rats were fed these diets for 2 weeks, and the feces were collected from each animal during the last 3 days. When compared with cellulose (control), 10 o...
Four experiments were conducted to evaluate lipid digestibility in finishing swine fed chemically hydrogenated fats. Dietary chromic oxide was used as an inert marker to measure the apparent digestibility of supplemental fat (SF) that consisted of fully hydrogenated (FH), partially hydrogenated (PH), or PH products blended with other fat sources. In Exp. 1, diets containing 5% SF (as-fed basis)...
The present study was aimed at studying the effects of inclusion of pomegranate seed extract to fat-containing diets on nutrients digestibility, intestinal microflora and performance of broilers. A total of 320 one-day-old broiler chicks (Ross 308) were selected in a 2 × 2 × 2 factorial experiment in a completely randomized design with 4 replicates o...
