Effects of Dietary Protein and Energy Levels on Productive and Reproductive Performance of Lactating Buffaloes
Twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (LP-LE), low protein–high energy (LP-HE), high protein–low energy (HP-LE) and high protein–high energy (HP-HE). Results showed that the HP-HE diet recorded the highest digestibility coefficients of CP, EE, NFE, nutritive values, ...
متن کاملEffects of Dietary Calcium Levels on Productive Performance, Eggshell Quality and Overall Calcium Status in Aged Laying Hens
This study was conducted to investigate the effects of diets with varying levels of calcium on egg production, shell quality and overall calcium status in aged laying hens. A total of five hundred 70-wk-old Hy-Line Brown layers were divided five groups and fed one of the five experimental diets with 3.5%, 3.8%, 4.1%, 4.4%, or 4.7% Ca, for 10 weeks. There were no significant differences in feed ...
متن کاملSome Productive, Reproductive and Physiological Effects of Using Different Dietary Protein Levels in Rabbit Does
Three groups of 11 New Zealand White (NZW) rabbit does, each were reared from 12 weeks of age on iso-energetic diets containing 16, 14 or 12% crude protein (CP) were used to study influences on productive performance, digestibility, some carcass traits, haematological, biochemical and hormonal parameters of rabbit does. The results showed rabbits fed on 16% protein diet had heavier body weights...
متن کاملA note on inbreeding effect on productive and reproductive traits in laying hens
Inbreeding rate and effects on production (body weight, age at first egg, egg weight), and reproduction (per cent of eggs fertilized, per cent of eggs hatched as related to eggs set) traits were evaluated in 9194 layers belonging to two strains. The individual inbreeding coefficients were calculated using Wright’s formula from available performance records across nine generations. The inbreedin...
متن کاملEffects of Dietary Dihydropyridine Supplementation on Laying Performance and Fat Metabolism of Laying Hens
The experiment was conducted to investigate the effects of dihydropyridine on laying performance and fat metabolism of laying hens. Five hundred and forty laying hens, 40 weeks old, were randomly allotted to three groups, each of which included four replicates of 45 hens. The groups were given a basal corn-soybean meal diet supplemented with 0, 150 mg/kg and 300 mg/kg dihydropyridine. Results s...
