Effect of dietary energy and protein content on growth and carcass traits of Pekin ducks
A study was conducted to determine the influence of dietary energy and protein concentrations on growth performance and carcass traits of Pekin ducks from 15 to 35 d of age. In experiment 1, 14-d-old ducks were randomly assigned to 3 dietary metabolizable energy (11.8, 12.8, and 13.8 MJ/kg) and 3 crude protein concentrations (15, 17, and 19%) in a 3×3 factorial arrangement (6 replicate pens; 66...
متن کاملEffects of stocking density on growth performance, carcass traits, and foot pad lesions of White Pekin ducks.
Two experiments were conducted to study the effects of stocking density on growth performance, carcass yield, and foot pad lesions of White Pekin ducks from hatch to 14 d of age (experiment 1) and from 14 to 42 d of age (experiment 2), respectively. All ducks were reared in raised plastic wire-floor pens with a pen size of 30 m(2), and males and females were mixed at a ratio of 1:1 in each pen ...
متن کاملThe effect of age on the growth rate of tissues and organs and the percentage content of edible and nonedible carcass components in Pekin ducks.
Age has a significant effect on carcass tissue composition, which is an important consideration in slaughter animals because age-related changes are observed in both edible and nonedible carcass components. In this study, the above changes were analyzed in Pekin ducks. The weight of individual edible and nonedible components in ducks increased for different periods of time, and the growth rate ...
متن کاملEffects of Pyridoxine on Growth Performance and Plasma Aminotransferases and Homocysteine of White Pekin Ducks
A dose-response experiment with seven supplemental pyridoxine levels (0, 0.66, 1.32, 1.98, 2.64, 3.30, and 3.96 mg/kg) was conducted to investigate the effects of pyridoxine on growth performance and plasma aminotransferases and homocysteine of White Pekin ducks and to estimate pyridoxine requirement for these birds. A total of 336 one-day-old male White Pekin ducks were divided to 7 experiment...
