Lysine requirement for maintenance in growing pigs
Probably due to methodological problems the knowledge about the AA requirement for maintenance in pigs is rather scarce. In the present study an alternative experimental approach was applied and its underlying hypothesis was tested, whether protein retention decreases with body weight (BW), when daily lysine intake remains constant and acts as the limiting factor for protein retention, and whet...
متن کاملLysine Requirement for Barrows Fed Ractopamine
and ADFI at week 4 (P = 0.02). During phase 2 (week 3 to 4), greater ADG (P = 0.05) and ADFI (P = 0.004) were observed in pigs consuming a diet containing DDGS (Treatments B and D) compared to pigs that did not receive DDGS in phase 1 (Treatments A and C); however, G:F ratio was not affected by DDGS. There was a lactose effect on ADG in week 3 (P = 0.05) and a trend of lactose effect on ADG dur...
متن کاملRequirement of the laying hen for apparent fecal digestible lysine.
A study was conducted to determine the requirement for lysine of a White Leghorn strain of hens with a body weight of approximately 1,600 g. Before starting the experiment, apparent fecal digestibility of amino acids of the basal diet was determined in an in vivo digestibility trial with six individually housed hens. The basal diet used was based on corn and soybean meal and contained 0.65% tot...
متن کاملThe lysine requirement and ratio of total sulfur amino acids to lysine for chicks fed adequate or inadequate lysine.
Experiments (Exp.) were conducted with Cornish Rock males (4 to 14 or 15 d of age) to determine the Lys requirement (Exp. 1) and the optimum ratio of TSAA:Lys for chicks fed adequate or inadequate Lys (Exp. 2). In Exp. 1, 180 chicks were allotted on the basis of BW to six treatments with six replications of five chicks each in a completely randomized design (CRD). Average initial and final BW w...
متن کاملDigestible lysine requirement of female turkeys during the starter period.
Three experiments were conducted to determine the digestible lysine requirement of female turkey poults during the starter period. Birds were fed a standard corn-soybean meal diet until the onset of each trial and were then randomly assigned to treatments that were fed for 2 wk. Dietary treatments included titrated levels of digestible lysine (1.18 to 1.72%) added to a basal corn-soybean meal d...
