Estimation 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 کاملThe optimum ratio of standardized ileal digestible leucine to lysine for 8 to 12 kg female pigs.
The objective of the study was to estimate Leu requirement for weaned piglets to balance indispensable AA in reduced CP diets. A dose-response experiment was conducted to estimate the standardized ileal digestible (SID) Leu to Lys ratio required for the maximum growth of young pigs after weaning. In this study, 96 female pigs (initial BW of 8 kg) were allotted to 1 of 6 dietary treatments with ...
متن کاملThe standardized ileal digestible valine-to-lysine requirement ratio is at least seventy percent in postweaned piglets.
To reduce the impact of animal production on the environment, the CP content of the diet can be reduced by limiting the excess supply of AA. Improving the balance between AA relative to the requirement of the animal implies that we need to have accurate knowledge of the requirement of individual AA. The purpose of this study was to determine the Val requirement in postweaned piglets (12 to 25 k...
متن کاملEvaluation 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, ...
