Effects of Dietary Regimens and Brown-Egg Pullet Strain on Growth and Development
This study consisted of; two strains of brown-egg pullets, the Hy-Line (HB) and H&N (BN) Brown were raised on three different dietary regimens resulting in a 2 x 3 factorial design. The three different regimens were a standard Step-down Protein Regimen (SDP) comprised of a 20% CP Starter, 0-6 week, 18% CP Grower 1, 7-12 week and 16% CP Grower 2, 13-18 week; a Step-up Protein Regimen (SUP9) comp...

متن کاملFailure of bone phosphorus levels to indicate dietary intake of phosphorus by sheep.
Fifteen actively growing lambs were divided into 3 groups and fed diets similar in all respects except for their calcium (Ca) and phosphorus (P) levels. The diets (Group 1; 1,47% Ca, 0,36% P: Group 2; 0,85% Ca, 0,47% P: Group 3; 0,37% Ca, 0,64% P) were fed to the animals for 98 days, when rib biopsy specimens were removed and analysed for Ca and P (Group 1; 21,20% Ca, 10,49% P: Group 2; 19,54% ...
متن کاملEffects of dietary protein on restrict-fed broiler breeder pullets during a coccidial challenge.
In each of two experiments with young, feed-restricted broiler breeder pullets, the effects of differences in dietary protein intake on intestinal development and growth were studied. All pullets were restrict-fed either a 15 or 19% CP diet to see whether differences in dietary protein would influence intestinal growth in the face of controlled exposure to coccidiosis. In each experiment, pulle...
متن کاملPlantain Ash Enhances Dietary Mineral Elements Absorption in Pullets
Generally, only a fraction of the mineral ingested by an animal is effectively absorbed, while most are bound to other components such as fibre and then excreted. In this study, faecal mineral composition differentials were used as indicators of mineral uptake by pullets supplemented varying levels of plantain ash in their daily rations for nine weeks. Plantain stalk and root base samples were ...
