Effect Of Formulating Diets To Reduce Excess Amino Acids On Performance Of Growing And Finishing Pigs, G.W. Libal, D.N. Peters
Effect Of Formulating Diets To Reduce Excess Amino Acids On Performance Of Growing And Finishing Pigs, G.W. Libal, D.N. Peters
South Dakota Swine Research Report, 2001
For every stage of growth, pigs have a requirement for essential amino acids provided in a specific ratio and for additional nitrogen provided as amino acids or other nitrogen sources to allow synthesis of nonessential amino acids. The typical manner of balancing swin diets has involved supplying several traditional feed ingredients in a ratio in the diet that meets the required level of the most limiting amino acid leaving excesses of most other amino acids. With this method, considerable nitrogen above that needed for nonessential amino acid synthesis is provided and excess nitrogen is excreted in the urine as urea. …
Effects Of Feeding Diets Formulated With Amino Acid Profiles Intended For High-, Medium-, And Low-Lean Gain Pigs On The Performance Of Medium-Lean Gain Pigs, G.W. Libal, C.R. Hamilton, D.N. Peters
Effects Of Feeding Diets Formulated With Amino Acid Profiles Intended For High-, Medium-, And Low-Lean Gain Pigs On The Performance Of Medium-Lean Gain Pigs, G.W. Libal, C.R. Hamilton, D.N. Peters
South Dakota Swine Research Report, 2001
The University of Nebraka and South Dakota State University published a Swine Nutrition Guide with nutrient recommendations for pigs in a four-phase feeding system for 20 to 114 kg. The recommendations utilized the concepts of split sex feeding, ideal protein profile relative to lysine, and reduction of nitrogen excretion by lowering the total protein content of the diet with dietary supplementation with economically available amino acids The research reported in this paper was an attempt to evaluate the consequences of feeding diets formulated for three lean groth genotypes to pigs of the medium-lean growth type.
