Limiting amino acids for growing lambs fed a diet low in ruminally undegradable protein.
Ruminally cannulated Rambouillet wether lambs were used in three 6 x 6 Latin square experiments (n = 6/experiment) to determine which essential AA limit N retention. Lambs (BW = 36.9 +/- 1.9 kg for Exp. 1, 35.1 +/- 1.4 kg for Exp. 2, and 46.0 +/- 1.3 kg for Exp. 3) were housed in metabolism crates and limit-fed (DMI = approx. 1.8% of BW daily) twice daily a soybean hull-based diet low in rumina...
متن کاملIntestinal supply of amino acids in steers fed ruminally degradable and undegradable crude protein sources alone and in combination.
The objective of this study was to examine the effect of combining ruminally degradable and undegradable CP sources on ruminal microbial protein synthesis and postruminal N and amino acid (AA) flows in steers. Six steers fitted with ruminal, duodenal, and ileal cannulas were fed diets containing corn silage and high-moisture corn supplemented with urea, soybean meal (SBM), dry corn gluten feed ...

متن کاملThe effect of supplementing rumen undegradable unsaturated fatty acids on marbling in early-weaned steers.
The objective of this study was to determine if supplementation with a rumen undegradable unsaturated fatty acids (FA) source improved marbling deposition in early-weaned steers. All steers (Angus, = 23; Angus × Hereford, = 24) were weaned at 150 ± 5 d of age. Steers were blocked by BW and breed and then randomly assigned to either control (CON; average 1.5 kg of corn gluten feed [CGF], = 23) o...
متن کاملEffects of Rumen Undegradable Protein on Productive Performance and N Balance of Holstein Cows in Early Post-Partum Period
Metabolizable protein (MP) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources. Effects on production efficiency and N utilization of early post-partum dairy cows were determined. Forty-two multiparous and 16 primiparous Holstein cows were assigned to the diets in a randomized complete block design immediately after part...
