Effects Of Protein Level And Gender On Estimation Of Lean Gain Per Day Of Pigs From A Terminal Crossbreeding System, G.W. Libal, C.R. Hamilton, J.N. Tembei

Lean growth potential is currently used to typify pigs when designing nutritional programs The most common method of estimating lean growth type is by measuring gain over the growth-finsih period and obtaining carcass information for the pigs evaluated. This information is placed in a model to calculate lean gain/day. Excess protein is fed to ensure that the genetic potential for lean gain per day is not limited by nutrition. The data reported herein are the results of determining the lean growth potential of the SDSU research herd in 1992 with pigs fed two different protein regimens.
Lean Growth And Overall Performance Of Pigs During The Finisher Phase As Affected By Lean Growth Potential Determined During The Grower Phase And Dietary Protein Level During The Finisher Phase, J.N. Tembei, G.W. Libal, D.N. Peters

Selection for decreased backfat thickness and faster rate of gain has resulted in pigs with increased potential for lean gain. Although energy intake is the limiting factor for lean growth during the grower period, the underlying limiting factor to support increased protein accretion during the finishing stage seems to be lysine intake. At the finishing phase, pigs consume enough feed per day to meet their energy requirements, but protein is the most limiting nutrient Genetics and sex influence growth performance and protein accretion in finishing pigs. Pigs from different protein requirements and these differences have been associated with differences in …
