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
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 …

Individual pig weights were recorded at the beginning of the experiment and every two weeks thereafter. The amount of feed dumped in each feed was recorded on a daily basis and feed in the feeders was recorded each time the pigs were weighed. At slaughter, indvidual live wights, the dressed weights, fat depth, loin depth, and the lean meant percentage were measured for each pig. At the end of the experiment, feed disapearance for each pen was calculated for each period. Likewise, average daily weight gain and average gain to feed ratios were calculated for each pen.

The effects of environmental conditions on performance of growing pigs (30-50 kg) were studied over a four-week period. Pigs were exposed to natural occurring diurnal temperatures and a constant 32°C ambient temperature during normally hot weather conditions and constant 21 and 10°C ambient temperature conditions during cold weather. For each temperature treatment pigs were divided into single, 9 and 18 head per pen groups. The constant 32°C ambient temperature had a significant (P<0.05) effect on average daily gain and feed intake. Average daily gains were reduced from 0.72 to 0.64 kg/d and average daily feed intake was reduced from 1.53kg/d to 1.36 kg/d when comparing pig performance from the naturally occurring diurnal to constant 32°C temperature treatments. The 10°C cold weather treatment had no significant {P>0.05) effects on overall pig performance. Pigs from the 10°C treatment gained at a rate of 0. 72 vs 0.74 kg/d for pigs in the 21°C treatment. …
