The study was performed to investigate the effect of combinations of feed additives consisting of either a combination of a probiotic and a prebiotic (synbiotic), or a combination of a probiotic and xylanase on ileal nutrient digestibility, ileal microbial metabolite concentrations, and microbial composition in ileal digesta of weaned piglets. In total, 12 six-week old barrows with an average i...

Because wheat forage contains high concentrations of N, NPN, digestible DM, and water, beef cattle and sheep require an adaptation period before positive BW are seen. The objective of the present experiment was to determine the impact of length of exposure of lambs and steers to wheat forage on BW gains, N retention, and forage digestibility. Sixteen steer calves (average BW = 210 +/- 12 kg) an...

Increasing cost and scarcity of maize has stimulated the use of alternative feed sources (AFS) in the diets of cattle. In this study, we investigated the effects of partial or total replacement of maize on nutrient digestibility, growth performance, blood metabolites, and economics in Limousin crossbred feedlot cattle. Forty-five Limousin×Luxi crossbred bulls were randomly assigned to the three...

the replacement of corn silage with varying levels of ammonia gassed wheat straw on performance, digestibility, fermentation parameters, chewing activities, blood metabolites and profitability of holstein heifers have been evaluated. fifteen holstein heifer with 9-10 months of age were assigned in a completely randomized design with 3 treatment as 1) 36% corn silage, 2) 18% corn silage and 18% ...

The objective of this study was to determine the effect drought stress on neutral detergent fiber (NDF) and lignin (LIG) concentrations in vitro dry matter digestibility (IVDMD) (IVNDFD) leaf blades stem internodes corn for silage. Eight plots were blocked (i.e., 4 blocks) randomly subjected a watered (W) or non-watered (NW) treatment. Within each block, split into 7 sub-plots, which 1 hybrids ...

Three 2.4-ha wheat (Triticum aestivum L.) fields were used to test the effects of maturity at harvest (boot vs. dough) and preservation method (hay vs. silage) on forage yield, chemical composition, and animal performance when fed in mixed diets. Forages were incorporated into 4 diets in a 2 x 2 factorial arrangement of treatments with hominy feed, soybean hulls, and cottonseed meal as the prim...

The aim of present experiment was to investigate the feeding value of wild pistachio leaf (khinjuk leaf, KL) for Arabi sheep. The digestibility and fermentation of diets containing different amounts of khinjuk (0, 5, 10, 15, 20, 25 and 30%) were measured. Then, the effect of presence of KL in the diet and its tannin content on the digestibility of alfalfa hay (Alfa), wheat straw (WS) and soybea...

Sheep fitted with rumen and re-entrant duodenal cannulas were given diets of approximately 200 g hay and 400 g concentrate mixture alone, or supplemented daily with 40 g linseed or coconut oils free or protected with formaldehyde-casein in a 5 x 5 Latin-square arrangement. Chromic oxide paper was given as a marker at feeding time and passage to the duodenum of neutral-detergent fibre (NDF) and ...
