Effect of hen weight on egg production and some egg quality characteristics in the partridge (Alectoris graeca).
A study was conducted to determine the effect of live weight of partridges on egg production and egg quality characteristics. A total of 144 Rock Partridges were divided into control, heavy, middle, and light BW groups at 32 wk of age. Live weights averaged 512.78 g for the control group, 576.18 g for the heavy group, 523.49 g for the middle group, and 473.83 g for the light group. Egg producti...

Fifty game pheasants were kept to 8 weeks in confinement housing and later maintained outdoors in a partially roofed aviary. Pheasants received commercial feed mixtures ad libitum. Body weight and dimensions were determined every 4 weeks. Ten pheasants were selected for slaughter at the end of 18 and 20 weeks each. After slaughter, their heads, shanks, feathers, blood, inedible viscera and majo...

متن کاملEffect of the Date of Egg-laying on the Biological Value of Eggs and Reproductive Traits in Pheasants (Phasianus colchicus L.)
Pheasant eggs evaluated in the first period of egg-laying did not differ significantly in their weight and shape index and the values of both traits were, respectively, 30.7 to 32.2 g and 76.1 to 78.1%. Over the laying season the thickness of the shell decreased and its capacity for deformation and crush strength were greatest at the end of the laying season. The share of yolk in the egg was hi...
