Effect of fodder protein solubility on the effectiveness of nitrogen assimilation in sheep digestive tract

, : Effect of fodder protein solubility on the effectiveness of nitrogen assimilation in sheep digestive tract. Doklady Vsesoyuznoi Ordena Lenina i Ordena Trudovogo Krasnogo Znameni Akademii Sel'skokhozyaistvennykh Nauk Imeni V I Lenina (1): 27-29

N metabolism and the effectiveness of N assimilation depending on fodder protein solubility were studied in 4 sheep with external anastomoses between the omasum and abomasum. Plant protein solubility significantly affected the effectiveness of N assimilation. Readily soluble proteins changed into microbial protein in the rumen and slightly soluble proteins went to the small intestine where they were digested. A combination of readily and slightly soluble proteins in the ration is recommended for highly productive ruminants, whose demand for protein exceeds microbial synthesis potential.
