Evaluation of standardized ileal digestible lysine requirement of nursery pigs from seven to fourteen kilograms.
Four experiments were conducted to determine the standardized ileal digestible (SID) Lys requirement of pigs (Sus scrofa) from 7 to 14 kg. In Exp. 1, 294 pigs (6.8 kg BW) were used in a 28-d growth trial with 7 pigs per pen and 7 pens per treatment. Treatment diets were fed from d 0 to 14, and a common diet was fed from d 14 to 28. The 6 SID Lys levels tested were 1.15, 1.23, 1.30, 1.38, 1.45, ...
متن کاملEstimation of the standardized ileal digestible valine-to-lysine ratio in 13- to 32-kilogram pigs.
Three experiments were conducted to determine the optimum standardized ileal digestible Val-to-Lys (SID Val:Lys) ratio for 13- to 32-kg pigs. In Exp. 1, 162 pigs weaned at 17 d of age (8 pens/treatment) were used, and a Val-deficient basal diet containing 0.60% l-Lys·HCl, 1.21% SID Lys, and 0.68% SID Val was developed (0.56 SID Val:Lys). Performance of pigs fed the basal diet was inferior to a ...
متن کاملStandardized Ileal Digestible Lysine Requirement of 6- to 10-kg Weanling Pigs
Corresponding Author: Beob Gyun Kim Department of Animal Science and Technology, Konkuk University, Seoul, Republic of Korea Email: [email protected] Abstract: The objective of the experiment was to determine the Standardized Ileal Digestible (SID) lysine requirement for weanling pigs from 6 to 10 kg of Body Weight (BW). A total of 216 weanling pigs with an initial BW of 6.23±0.93 kg were assi...
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 کاملInfluence of a gonadotropin-releasing hormone vaccine and dietary standardized ileal digestible lysine level on growth performance and carcass quality of grower-finisher pigs.
The aim of this study was to assess the effect of standardized ileal digestible (SID) Lys levels of the diet on the growth performance, carcass characteristics, and meat quality of entire males (EM), surgical castrates (SC), and males vaccinated with a gonadotropin-releasing hormone (GnRH) vaccine (GV). In total, 252 crossbred pigs were fed 6 different experimental diets consisting of 3 sexes (...
