Characterization of Production and Reproduction Performances in Rhode Island Red-White Strain Chicken
This study aimed to characterize production and reproduction performances in Rhode Island Red-White strain chicken developed and maintained at the Central Avian Research Institute, Izatnagar. Three hundred and forty six fertile eggs were set in automated electric incubation and 234 chicks were investigated in three hatches. The performance data was analyzed by least squares analysis of variance...
متن کاملEffects of disuse on growing and adult chick skeletal muscle.
The effects of long-term muscle inactivity, throughout post-hatching development, have been examined. Continuous immobilization of the chicken posterior latissimus dorsi (PLD) muscle from the first hour after hatching for varying periods up to 330 days, resulted in a significantly greater decrease in myofibre size (40-64% less than control) than occurred when adult muscles were immobilized for ...
متن کاملA Chick Embryo in-Vitro Model of Knee Morphogenesis
Background: In this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. Methods: The developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of ...
متن کاملPredicting Chick Quality: Which Is Best - Chick Length or Hatch Day Body Weight?
Measuring chick quality has been a difficult issue since the beginning of the poultry industry. There have been many attempts over the decades to evaluate chick quality in the hatchery to predict future performance in the broiler house. One can examine chicks in the hatchery and enumerate conditions such as the incidences of red hocks, open navels, string navels, and other abnormalities. In mos...
