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...

15 صفحه اولLysine 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 کاملSunflower Meal and Enzyme Supplementation in Diets of Broilers from 21 to 42 Days of Age
The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...
متن کاملCottonseed Oil in Diets for Broilers in the Pre-Starter and Starter Phases
The objective of this study was to evaluate the effect of different levels of crude cottonseed oil in isoenergetic diets, with or without supplementation of ferrous sulfate, on performance variables, relative weight of organs, and blood parameters of broilers, and on the economic viability of diets in the periods from 1 to 7 and 1 to 21 days of age. A total of 600 male birds of the Ross line we...
