Influence of dietary lysine on growth performance and carcass characteristics of late-finishing gilts.
We conducted two experiments evaluating the lysine requirement of 91- to 113-kg gilts. Gilts (PIC L326 x C-22) with initial body weights of 42 (Exp. 1) or 39 kg (Exp. 2) were blocked by weight in a randomized complete block design. Experiment 1 included 105 gilts, with seven gilts per pen and five replications (pens) per treatment. Experiment 2 included 125 gilts, with eight gilts per pen and f...
متن کاملInfluence of dietary total sulfur amino acids and methionine on growth performance and carcass characteristics of finishing gilts.
We conducted three experiments to determine the sulfur amino acid (SAA) and methionine requirements of finishing gilts. Gilts (PIC Line 326 x C-15, Exp. 1; Line 326 x C-22, Exp. 2 and 3) were blocked by initial weight in randomized complete block designs. In Exp. 1, 64 gilts (initially 54 kg) were fed diets containing either .56 or .44% apparent digestible lysine with increasing SAA levels (63,...
متن کاملEffect of Lysine to Digestible Energy Ratio on Growth Performance and Carcass Characteristics in Finishing Pigs
This experiment was performed to investigate the effects of lysine (Lys) to DE ratio on growth performance, and carcass characterics in finishing barrows. Ninety six cross-bred finishing barrows ((Landrace×Yorkshire) ×Duroc, average BW 58.25±0.48 kg) were assigned as a randomized complete block design by 2 energy levels and 4 Lys:DE ratios on the basis of BW to one of 8 treatments with 3 replic...
متن کاملEffects of Gender and Dietary Ionophores on Growth Performance and Carcass Characteristics in Moghani Lambs
An experiment was carried to evaluate the effects of gender and two dietary ionophores on growth performance and slaughter characteristics in Moghani sheep. A total of 30 Moghani lambs (15 males and 15 females) were distributed randomly into 30 individual cages. Each gender group consisted of 5 animals and fed with a basal diet with no supplement, the same basal diet plus 25 mg/kg monensin (MON...
متن کاملEffects of dietary lysine and energy density on performance and carcass characteristics of finishing pigs fed ractopamine.
Two hundred sixteen crossbred barrows and gilts (84.3 kg BW) were used to test the effects of dietary energy density and lysine:energy ratio (Lys:ME) on the performance, carcass characteristics, and pork quality of finishing pigs fed 10 ppm ractopamine. Pigs were blocked by BW and gender, allotted to 36 pens (six pigs per pen), and pens were assigned randomly within blocks to dietary treatments...
