digestibility coefficient of whole cottonseed was determined by in vivo method and total collection feces. the whole cottonseed degradability was determined by nylon bag method. a number of 12 holstein bulls were used in a complete randomized design. the rations contained zero (control), seven, 14 and 21 percentages of whole cottonseed. during the experimental period, daily gain, dry matter int...

The objective of these studies was to determine if dietary enzymes increase the digestibility of nutrients bound by nonstarch polysaccharides, such as arabinoxylans, or phytate in wheat millrun. Effects of millrun inclusion rates (20 or 40%), xylanase (0 or 4,375 units/kg of feed), and phytase (0 or 500 phytase units/kg of feed) on nutrient digestibility and growth performance were investigated...

Thirty-five available feeds were fermented in vitro in order to investigate their soluble total organic carbon (TOCs) and methane (CH4) production rate. A fermentation reactor was designed to capture the CH4 gas emitted and to collect liquor from the reactor during in vitro fermentation. The results showed that CH4 production rate greatly varied among feeds with different ingredients. The lowes...

Four Holstein steers (208 kg) with "T" cannulas in the rumen and proximal duodenum were used in a 4 x 4 Latin square design experiment to evaluate the interaction of feed intake level on comparative ruminal and total tract digestion of dry-rolled and steam-flaked corn. The basal diet contained (DM basis) 6% alfalfa hay, 6% sudangrass hay, 75% corn, 2% yellow grease, 5% cottonseed meal, 3% cane ...

This study examined mean retention time (MRT) of particulate and liquid matter in different segments of the gastrointestinal tract (GIT) of growing Saanen goats of different sexes and subjected to different levels of feed restriction. In addition, feeding behavior and total tract digestibility were determined for all animals ahead of slaughter. In total, 54 Saanen goats (18 each of females, cas...

Effect of supplemental phytase on phosphorus and protein utilization and performance of broiler chickens fed on eight different wheat varieties were evaluated. The phytate contents of wheat varieties were determined. In a completely randomized design with a 8*3 factorial arrangement, 384 day-old commercial male brioler chicks (HubbardPeterson) were divided into 96 groups, four chicks per group...

24 A study was conducted with Senegalese sole (Solea senegalensis) to determine the 25 apparent digestibility coefficients (ADCs) of protein, phosphorus and energy in 26 practical feed ingredients. The digestible energy (DE) content was also evaluated. 27 Test ingredients were anchovy fishmeal, solvent-extracted soybean meal, corn 28 gluten and wheat meal. Due to their low cohesion, sole faeces...

1. The use of a nylon-bag technique for pig feed digestibility determination was studied. Bags, measuring 25 x 40 mm and containing feed samples, were introduced into the pig gastrointestinal tract through a duodenal cannula, and recovered in the faeces between 23 and 69 h later. The disappearance of organic matter and crude protein (nitrogen x 6.25) from the bags was compared with in vivo appa...

in the first experiment, the nitrogen corrected apparent metabolizable energy (amen) and nutrients apparent digestibility of full fat soybean (ffsb) extruded at 145, 155 (common temperature) and 165 o c were evaluated. the corn-soy based diets were replaced with zero, 7.5, 15 and 22.5 % of each ffsb extruded at three temperatures during 15-21 d of age and amen and nutrients digestibility of eff...

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 ...
