Lysine Supplementation of Turkey Grower Diets
Commercial Australian White turkey poults, kept in small pens, were fed commercial diets until 8 weeks. Poults were then fed either 20 per cent dietary protein, with or without added lysine, or 24 per cent dietary protein, each with a metabolizable energy content of either 11.5 or 12.75 MJ/kg. The poults fed on the 24 per cent protein diet were heavier than those on the 20 per cent protein diet...
متن کاملDigestible 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 کاملDetermining the Threonine Requirement of the Lactating Sow
A total of 182 lactating sows were used in a study to determine the threonine requirement, and the relative difference in resulting performance of lactation diets with high concentrations of crystalline amino acids, compared with a conventional corn-soybean meal diet. All experimental diets were based on corn-soybean meal and formulated to contain 0.88% true ileal digestible (TID) lysine (1.00 ...
متن کاملThe threonine requirement of sows increases in late gestation.
Current AA recommendations for sows are to provide a fixed amount of AA intake throughout gestation based on the assumption that there is a constant demand for AA; however, the demand for nutrients changes from maternal lean tissue in early gestation to fetal and mammary growth in late gestation. The objective of this study was to determine the Thr requirement in early (d 35 to 53 and 25 to 55 ...
متن کاملThreonine requirement of slow-growing male chickens depends on age and dietary efficiency of threonine utilization.
Nitrogen-balance experiments were conducted with a total of 288 male chickens to assess Thr requirement data on 2 commercial slow-growing genotypes (I 657 and Red JA from Hubbard ISA) by use of a modeling procedure described previously. Six graded levels of dietary protein supply from high-protein soybeanmeal were used within 4 age periods (period I: 10 to 25 d; period II: 30 to 45 d; period II...
