Determining the Digestible Lysine and Lysine: Threonine Ratios for Growing Turkeys
There have been relatively few lysine requirement studies that have covered the full productive life of commercial toms (0 to 20 wk). Lysine is the reference amino acid for Ideal Protein ratios and accurately defining the requirement reduces fractional errors in the corresponding ideal protein ratios. A series of studies were conduct to determine the lysine concentrations (total and digestible)...
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 کاملCholecystokinin-8 activates myenteric neurons in 21- and 35-day old but not 4- and 14-day old rats.
Cholecystokinin (CCK) activates the myenteric neurons of adult rats. The goal of this work is to determine the ontogeny of this activation by CCK-8 in the myenteric plexus of the duodenum (2cm immediately following the pyloric sphincter aborally) and compare it with that of the dorsal vagal complex (DVC) - which occurs in 1-day old pups. Despite the existence of both of the CCK receptors, CCK(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...
