Three experiments were conducted to determine the effects of enzyme supplementation and particle size of wheat-based diets on growth performance and nutrient digestibility in nursery and finishing pigs. In Exp. 1, 180 weaned pigs (5.7 kg and 21 d of age) were fed diets in a 35-d growth assay without or with a Trichoderma longibrachiatium enzyme product(More)
Two experiments were conducted to evaluate the effects of adding fiber sources to reduced-crude protein (CP), amino acid-supplemented diets on N excretion, growth performance, and carcass traits of growing-finishing pigs. In Exp. 1, six sets of four littermate barrows (initial weight = 36.3 kg) were allotted randomly to four dietary treatments to determine(More)
Four experiments were conducted to determine the effects of adding a beta-mannanase preparation (Hemicell, ChemGen, Gaithersburg, MD) to corn-soybean meal-based diets on growth performance and nutrient digestibility of weanling and growing-finishing pigs. In Exp. 1, 156 weanling pigs (20 d, 6.27 kg BW) were allotted to four dietary treatments in a(More)
Three experiments were conducted to determine the effects of omitting vitamin and trace mineral premixes and(or) reducing inorganic phosphorus additions to finishing diets on growth performance, carcass characteristics, and muscle quality in pigs. In Exp. 1, a corn-soybean meal-based diet (.70% lysine, .65% Ca, and .55% P) was used as the control. Pigs (n =(More)
Four experiments were conducted to evaluate the effects of supplementing graded levels (0 to 100 ppm) of L-carnitine to the diet of weanling pigs on growth performance during a 34- to 38-d experimental period. A fifth experiment was conducted to determine the effects of addition of L-carnitine to diets with or without added soybean oil (SBO) on growth(More)
Rate and efficiency of gain were not affected by adding as much as 20% distillers dried grains in isocaloric diets for nursery pigs or 30% in isocaloric diets for finishing pigs. These results demonstrate that the previously suggested maximums of 5% distillers dried grains in nursery diets and 10% distillers dried grains in finishing diets are too(More)
No differences occurred in ADG, ADFI, F/G, digestibilities of DM and GE, dressing percentage, 10th rib fat depth, or fat free lean index in pigs fed normal vs heterowaxy sorghums. As anticipated, with the greater fiber and lower energy in distillers dried grains with solubles (DDGS) than the parent cereal grains, ADG and digestibilities of DM and GE were(More)
fore, data were pooled across experiments (12 pens/trt). ADG, ADFI, and G:F for the 38-d study were: 394, 398, 370, and 391 g; 566, 567, 536, and 540 g; and .696, .703, .690, and .725, respectively. Pigs fed SBO tended (P<0.10) to grow slower and consume less feed compared to those not fed SBO, but G:F was not affected (P>0.10). The addition of L-carnitine(More)
Two experiments were conducted to determine the effects of sorghum-based distillers dried grains with solubles in isocaloric diets for nursery and finishing pigs. Rate and efficiency of gain in nursery pigs were decreased with 45% or more distillers grains. For finishing pigs, efficiency of gain was improved as distillers grains was increased to 60% of the(More)
