Two studies were conducted to evaluate the effects of diet on phosphorus (P) digestion in dairy cattle. The objective of the first study was to evaluate the effects of forage and non-fiber carbohydrate (NFC) content on total P (TP) and inositol phosphatesP (IPs-P) digestion. Samples of feed, duodenal digesta and feces from a previously conducted study were analyzed for TP and IPs-P. In this stu...

Two experiments using soybean meal (SBM) or canola meal (CM) were conducted to investigate whether the choice of digestibility marker influenced the apparent ileal digestibility (AID) or standardized ileal digestibility (SID) of N and AA in diets supplemented with phytase. In each experiment, 18 barrows fitted with T-cannulas at the ileocecal junction were assigned to 3 diets consisting of a N-...

Fifteen crossbred cattle bulls of about 22-24 months age (mean body weight ranged from 291.0 to 298.1 kg) were randomly divided into 3 groups of 5 animals following randomized block design. Animals in group 1 were fed concentrate mixture containing wheat bran 97%, mineral mixture 2% and salt 1% plus ad libitum chopped green sugarcane tops (SCT) as a roughage source. Animals in group 2 were fed ...

This study was designed to determine the effects of hydrolyzed feather meal inclusion on growth performance, carcass characteristics, nutrient digestibility and fecal odorous compounds in modern lean growth genotype pigs. Two hundred forty pigs (BW = 23.2 +/- 1.3 kg) were allotted based on BW and sex to a 2 x 6 factorial arrangement of treatments (four pens per treatment; five pigs per pen) in ...

to study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at college of agriculture, shaheduniversity in tehran, 2011. the main plots were allocated to different levels biofertilizer...

As environmental constraints become more important issues for the animal industry, selecting feed ingredients that yield good animal performance but also minimize environmental impact of animal production becomes critical. The objective of this research was to identify which compositional features would be desirable for soybean meal to maximize nutritional value and minimize animal waste. Eight...

sesame oil cake (ssc) was bio-processed through solid state fermentation (ssf) under optimized conditions by a phytase-producing fish gut bacterium, bacillus subtilis subsp. subtilis (jx292128). ssf significantly reduced anti-nutritional factors (e.g., phytic acid, tannins and trypsin inhibitor) and crude fibre, while enhanced free amino acids, fatty acids and different minerals. phytase product...
