Effects of excess dietary crude protein from soybean meal and dried distillers grains with solubles in diets for finishing pigs

Kansas Agricultural Experiment Station Research Reports, Dec 2008

A total of 180 pigs (90 barrows and 90 gilts, average initial weight of 148 lb) were used in a 67-d experiment to determine the effects of excess dietary CP on growth performance and carcass measurements in finishing pigs. The pigs were sorted by ancestry and blocked by weight with 12 pigs per pen and 5 pens per treatment. Treatments were corn-soybean meal-based diets formulated to 15.3 and 18.3% CP and a corn-soybean-DDGS-based diet formulated to 18.3% CP. Feed and water were consumed on an ad libitum basis until the pigs were slaughtered (average final weight of 282 lb) at a commercial abattoir. Pigs fed diets with high CP had lower (P < 0.001) final weight, ADG, ADFI, and HCW, but these results were caused entirely by the diet with 40% DDGS. Our results indicated that diets with 40% DDGS decreased growth performance and economically important carcass measurements. However, the excess CP in those diets does not seem to be the culprit.; Swine Day, 2008, Kansas State University, Manhattan, KS, 2008

The pigs were sorted by ancestry and blocked by weight with 12 pigs per pen and 5 pens per treatment. Treatments were cornsoybean meal-based diets formulated to 15.3 and 18.3% CP and a corn-soybean-DDGSbased diet formulated to 18.3% CP. Feed and water were consumed on an ad libitum basis until the pigs were slaughtered (average final weight of 282 lb) at a commercial abattoir. Pigs fed diets with high CP had lower (P < 0.001) final weight, ADG, ADFI, and HCW, but these results were caused entirely by the diet with 40% DDGS. Our results indicated that diets with 40% DDGS decreased growth performance and economically important carcass measurements. However, the excess CP in those diets does not seem to be the culprit. Key words: carcass, dried distillers grains with solubles, finishing pigs, growth, protein Introduction Many scientists (particularly in Europe) suggest that excess CP in diets reduces energetic efficiency in pigs. This lost efficiency should be reflected in poor growth performance measurements. Additionally, excess CP in diets has been blamed for increased organ weights leading to lower carcass yields. These arguments are of particular interest to us because diets with high inclusion of dried distillers grains with soluble (DDGS) have an abundance of CP. Thus, we designed an experiment to determine the effects of excess dietary CP from soybean meal vs. DDGS on growth performance and carcass measurements of finishing pigs. Procedures A total of 180 pigs (90 barrows and 90 gilts, average initial weight of 148 lb) were used in a 67-d growth assay. The pigs were sorted by sex and ancestry, blocked by weight, and assigned to pens. There were 12 pigs per pen and 5 pens per treatment. The pigs were housed in a finishing facility with 6-ft ? 16-ft pens having half solid and half slatted concrete flooring. Each pen had a self-feeder and nipple waterer to allow ad libitum consumption of feed and water until the pigs were slaughtered at an average weight of 282 lb. The first treatment was a corn-soybean meal-based diet formulated to 15.3% CP with (...truncated)
