Effect of Increasing Lysine:net Energy Ratio on Growth Performance and Plasma Urea Nitrogen Concentration of Late-Finishing Barrows Fed Low-Protein Amino Acid-Supplemented Diets and Ractopamine
Low-crude protein, amino acid-supplemented diets containing ractopamine balanced to contain 4.57 to 5.2 g of 1ysinelMcal of net energy can adequately supply amino acids for growth in late finishing pigs. Summary An experiment was conducted to determine the optimum lysine (lys):Net energy (NE) ratio of low-crude protein (CP) amino acid (AA)-supplemented diets needed in cor~jt~nction with racto-p...
متن کاملThe appropriate standardized ileal digestible tryptophan to lysine ratio improves pig performance and regulates hormones and muscular amino acid transporters in late finishing gilts fed low-protein diets1
This study investigated the effects of various standardized ileal digestible (SID) Trp to Lys ratios on the performance and carcass characteristics of late finishing gilts receiving low-CP (9.6%) diets supplemented with crystalline AA. Ninety gilts (89.1 ± 5.1 kg) were used in a dose–response study conducted for 35 d. Crystalline Trp (0, 0.1, 0.2, 0.4, or 0.6 g/kg) was added to a corn–wheat bra...
متن کاملEffects of adding fiber sources to reduced-crude protein, amino acid-supplemented diets on nitrogen excretion, growth performance, and carcass traits of finishing pigs.
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 N balance and slurry composition. Diet...
متن کاملEffect of dietary fiber or fat in low-crude protein, crystalline amino acid-supplemented diets for finishing pigs.
Three experiments were conducted to determine the effect of reducing NE, by adding dietary fiber in Exp. 1 and 2 and decreasing dietary fat in Exp. 3, of low-CP, crystalline amino acid (CAA)-supplemented diets for finishing pigs on growth performance and carcass characteristics. In Exp. 1 and 2, 64 barrows (Exp. 1) or gilts (Exp. 2) were allotted to four treatments with four replicates of four ...
متن کاملMilk Yield and Blood Metabolite Profile in Late Pregnancy in Lori Ewes Receiving Diets Containing Undegradable Protein Sources
An experiment was conducted to investigate the effects of supplementing Lori ewes with rumen-undegradable protein (RUP) in late pregnancy on their performance and that of their lambs. Milk yield and blood metabolite profile were measured. Forty pregnant ewes were used in a completely randomized design trial with four treatments: 1) a basal diet (control); 2) with a supplement of 5% fishmeal; 3)...
