this study was conducted to investigate the effects of doses of 25, 50 and 75 kgy of gamma ray (gr) and electron beam (eb) ionizing radiations on ruminal disappearance of amino acids (aas) and protein subunits of canola meal (cm). the nylon bag technique was used for degradability trial. three ruminally fistulated taleshi bulls were used for this aim. the disappearance trends of protein subunit...

The continuous input, slow decomposition, and retention of straw can impede tillage crop growth, the decomposition process in soil is affected by its composition method application. Experimental Station Jilin Agricultural University, Changchun City, Province. type was Argiudolls, experimental field area 30 m2, maize planted continuously for 12 years without returning to field. There were four t...

The present study was conducted to investigate the possibility of using a modified in vitro gas production technique in place of the nylon bag method to estimate protein degradability of alfalfa hay in ruminants. In the in situ experiment dacron bags were filled with 3 g alfalfa hay. This was incubated in the rumen of three ruminally cannulated Ghezel rams for the periods of 0, 2, 4, 8, 12, 16,...

This study was conducted to investigate the effect of biological treatment withPleurotus floridafungi on chemical composition and rumen dry matter (DM) and organic matter (OM) degradability of wheat and barley straw. Wheat and barley straw were collected from Golestan province of Iran and after pasteurization mixed with fungi spawn (than 5% by weight). After 21 days samples were dried in oven (...

Three techniques for estimating rumen protein degradability were used together with in vivo apparent nitrogen digestibility estimates from sheep fed dried chopped Pangola grass or Siratro. The techniques used were 1) nitrogen disappearance from nylon bags suspended in the rumen, 2) S labelling of rumen microbial protein with plant nitrogen degradability calculated as the difference between micr...

The objectives of this study were to determine an optimal cultivation time for populations of yeast and lactic acid bacteria (LAB) co-cultured in fermented milk and effects of soybean meal fermented milk (SBMFM) supplementation on rumen degradability in beef cattle using nylon bag technique. The study on an optimal cultivation time for yeast and LAB growth in fermented milk was determined at 0,...
