Reducing Dietary Crude Protein: Characterization of Branched-Chain Amino Acid Antagonism in Modern Broiler Chickens
<p>Reducing the crude protein content of broiler diets while maintaining performance has been a primary research area in nutrition. During the late 20th century, the bulk of this research has involved supplementing broiler diets with feed-grade amino acids and proving the economic benefits of their …

Effects of Amino Acid Supplementation of Reduced Crude Protein (RCP) Diets on the Performance and Carcass Quality of Growing-Finishing Swine
<p>Barrows and gilts (215/gender) were used to test the effects of synthetic AA supplementation of reduced CP diets on the growth performance and quality characteristics of the LM and the fatty acid composition of the LM and s.c. jowl fat from growing-finishing swine. Pigs were blocked by BW within …

Effects of Supplementing Crystalline L-Valine and L-Isoleucine and a Novel Threonine Biomass in Reduced Crude Protein Diets fed to Broilers
… A common approach is to reduce dietary crude protein (CP), the second most expensive component in a broiler diet. Subsequently, reducing CP will reduce the inclusion levels of intact protein sources (e.g., soybean meal [SBM]), which can be accomplished by supplementing individual amino …

The interaction between dietary crude protein and amino acid levels in weaner pigs in an antibiotic-free environment with or without Bacillus amyloliquefaciens supplementation
The interaction between dietary crude protein and amino acid levels in weaner pigs in an antibiotic-free environment with or without Bacillus amyloliquefaciens supplementation Natasha van Niekerk High crude protein (CP) diets cause a myriad of digestive problems in weaner pigs due to incomplete …

Nitrogen balance and nutrient requirements of young Nellore bulls fed with static or oscillating crude protein levels, and feeding behavior, water intake and requirements of bulls with different residual feed intakes
… study were 1) to evaluate the effects of dietary crude protein (CP) supply on intake, digestibility, performance, N balance, and requirements of young Nellore bulls, and 2) to determine feeding behavior, water intake, and requirements of high and low residual feed intake (RFI) Nellore bulls. 42 …

Intensive spring nitrogen management of winter barley: silage and grain yield and composition
… in 1985 and 1986 though dry conditions existed. Crude protein yield was increased with application of 135 kg N/ha all three years. Major impact of N. fertilization appeared to be associated with an application at Feekes stage 5. Nitrogen treatments had little impact on nitrate, NDF or ADF …
