Measurement of the Intestinal Digestibility of Rumen Undegraded Protein Using Different Methods and Correlation Analysis.
Four methods were adopted, including the mobile nylon bag (MNB) method, modified three-step in vitro (MTS) method, original three-step in vitro (OTS) method, and acid detergent insoluble nitrogen (ADIN) estimating method, to evaluate the intestinal digestibility of rumen undegradable protein (DRUP) of 10 types of concentrates and 7 types of roughages. After correlation analysis to determine the...
متن کاملRumen Degradability and Small Intestinal Digestibility of the Amino Acids in Four Protein Supplements.
The supplementation of livestock feed with animal protein is a present cause for public concern, and plant protein shortages have become increasingly prominent in China. This conflict may be resolved by fully utilizing currently available sources of plant protein. We estimated the rumen degradability and the small intestinal digestibility of the amino acids (AA) in rapeseed meal (RSM), soybean ...
متن کاملThe Effects of Xylose Treatment on Rumen Degradability and Nutrient Digestibility of Soybean and Cottonseed Meals
Two trials were conducted to evaluate the effect of xylose treatment on rumen degradability characteristics of DM, OM and CP and in vivo digestibility of DM, OM, CP and crude fiber (CF) of soybean meal (SBM) and cottonseed meal (CSM). In Trial 1, three ruminally cannulated Merino rams were used. Xylose treatments at both levels, 0.5 and 1%, decreased effective degradability of DM, OM and CP of ...
متن کاملDry Matter and Crude Protein Degradability ofMopane Worm (Imbrasia belina) in Rumen of Steers
Three cannulated Tswana steers were used to investigate the rumen degradability of mopane worm (Imbrasia belina) by measuring the amount of dry matter (DM) and crude protein (CP) disappearing at incubation periods up to 72 h. The effective degradability (ED) of DM and CP in the rumen was calculated at outflow rates of 0.03 / h (ED0.03) and 0.05 / h(ED0.05). Rumen degradable CP (RDP) was estimat...
متن کاملRuminal Protein Degradation and Estimation of Rumen Microbial Protein Production
Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...
