In vitro efficiency of combined acid-heat treatments for protecting sunflower meal proteins against ruminal degradation.
Efficacy of combined acid-heat treatments to protect crude protein (CP) against ruminal degradation has not been extensively researched. Four in vitro trials (Daisy technology) with orthophosphoric and malic acids were performed to examine effects on protection of sunflower meal protein. In Trial 1, effects of the solution volume for adding two doses of orthophosphoric acid (0.4 and 1.2 eq/kg s...
متن کاملMalic acid or orthophosphoric acid-heat treatments for protecting sunflower (Helianthus annuus) meal proteins against ruminal degradation and increasing intestinal amino acid supply.
The protection of sunflower meal (SFM) proteins by treatments with solutions of malic acid (1 M) or orthophosphoric acid (0.67 M) and heat was studied in a 3 × 3 Latin-square design using three diets and three rumen and duodenum cannulated wethers. Acid solutions were applied to SFM at a rate of 400 ml/kg under continuous mixing. Subsequently, treated meals were dried in an oven at 150°C for 6 ...
متن کاملEffect of fat coating on rumen degradation and intestinal digestibility of soybean meal
Three rumen and duodenum fistulated dairy cows were used to determine the effects of fat and methionine addition to soybean meal on rumen degradation of crude protein, the amino acid pattern and the intestinal digestibility of undegraded residues. The addition of 10% and 25% fat resulted in lower DM degradation after 8 and 24 h of incubation. Protein degradation was reduced by 10% fat addition ...
متن کاملDegradation in the rumen of proteins of 2 legumes: soybean meal and field pea.
Ruminal protein degradation of soybean meal and field pea were compared using 2 analytical methods: in situ and a laboratory analysis with a proteolytic enzyme extracted from Streptomyces griseus. The degradation of total nitrogen in nylon bags of the feeds was measured between 0 and 48 h in the rumen of 2 cows (theoretical degradability: 70.0% for soybean meal and 94.7% for field pea). Electro...
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...
