Digestible lysine requirement of starter and grower pigs.
Three experiments were conducted to determine the digestible lysine requirement of starter (6 kg BW initially) and of grower (21 kg BW initially) pigs. Experiment 1 used 294 starter pigs and lasted 28 d; Exp. 2 used 182 grower pigs and lasted 35 d. Protein and total lysine contents of the basal corn-peanut meal diets were 20 and .8% for Exp. 1 and 16 and .54% for Exp. 2. Basal diets were fortif...
متن کاملThe Optimal True Ileal Digestible Lysine and Threonine Requirement for Nursery Pigs
A total of 360 pigs (initially 22.2 lb and 31 d of age) was used in a 21-d growth assay. This trial was conducted as a combination of two separate trials in order to simultaneously examine both the true ileal digestible lysine and true ileal digestible threonine requirement and determine the appropriate threonine:lysine ratio. The first part of the trial consisted of five treatments with increa...
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 کاملCommercial validation of the true ileal digestible lysine requirement for eleven- to twenty-seven-kilogram pigs.
Five experiments utilizing 3,628 pigs were conducted to determine the true ileal digestible (TID) Lys requirement for 11- to 27-kg pigs fed corn-soybean meal diets. In Exp. 1, 216 barrows (initial BW = 11.5 kg) were used, with dietary TID Lys levels from 1.05 to 1.40% TID Lys (0.07% increments). All diets were isocaloric (3.42 Mcal of ME) and contained the same inclusion of soybean meal (33.1%)...
متن کاملDigestible Lysine Requirement of Female Turkeys During the Starter Period1,2
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...
