Ruminal degradability of neutral detergent insoluble protein of selected protein sources

In situ neutral detergent insoluble nitrogen as a method for measuring forage protein degradability.

A method of estimating the undegraded intake protein (UIP) concentration of forages was developed and validated with a series of in situ experiments. The hypothesis was that UIP calculated from in situ neutral detergent insoluble N (NDIN) is equal to total in situ N minus the microbial N that is estimated from purines (MN). The in situ disappearance rates of total in situ N (TN), MN, and NDIN w...

Ruminal Degradability Characteristics in Vegetable Protein Sources of Pakistan

Fifteen different vegetable protein sources found in Pakistan were evaluated for ruminal degradability characteristics through in situ procedure using rumen fistulated Nili-Ravi buffalo steer. Samples of soybean meal, corn gluten meal 60%, maize gluten feed, guar meal, sunflower meal, rapeseed meal, rapeseed cake, canola meal, cottonseed cake, cottonseed meal, coconut cake, coconut meal, palm k...

Use of Neutral Detergent Insoluble Protein in Omasal Samples to Estimate Escape Protein

Effect of Dry Matter Content and Inoculation on Ruminal Protein Degradability in Alfalfa Silages

The aim of the experiment was to determine the effect of different dry matter content and addition of silage inoculant on the ruminal protein degradability. Alfalfa herbage was collected from two cuts and the fresh matter was sampled two times during each cut (with different dry matter content). During the preparation of experimental micro-silages, the chopped forage was treated with a microbia...

Ruminal 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...
