Four ruminally cannulated multiparous cows averaging 73±13days in milk(DIM)were used in a 4× 4Latin square design to determine the effect of different dietary crude protein levels on ruminal fermentation and production performance. Each experimental period was 21d, which included a 14d of adjustment to experimental diets followed by 7days of sample collection. The diets contained[dry matter(DM)basis]20% alfalfa hay,
The objective of the experiment was to study the effect of intraduodenally infused soybean small peptide (SSP)on absorption of free amino acids and small peptide in lactating *** late lactating dairy goats (38.24±...

The objective of the experiment was to study the effect of intraduodenally infused soybean small peptide (SSP)on absorption of free amino acids and small peptide in lactating *** late lactating dairy goats (38.24±2.73kg BW,milk production 0.5～1.0kg/d)were used in a 4×4 Latin square *** were fit- ted with duodenal cannulas and implanted with indwelling catheters in carotid artery, proximal and distal mesen-
