Effect of Egg Weight on Egg Traits and Hatching Performance of Turkey (Meleagris gallopavo) Eggs
The study was conducted to determine the effects of turkey (Meleagris gallopavo)egg weight on certain egg traits and hatching performance. A total of 178 turkey eggs comprising of three different egg weight groups below 60 g (G I), 61 to 69 g (G II) and above 70 g (G III) were used for this study. Average egg weight (g), egg length (cm), egg breadth (cm) and egg volume (cm3) values increased wi...
متن کاملEffect of Ochratoxin A on Body Weight, Feed Intake and Feed Conversion in Broiler Chicken
The effect of ochratoxin A (OA) on the body weight, feed intake, and feed conversion was investigated in broiler chicken fed dietary levels of OA at 0, 1, and 2 ppm for 28 days from hatch. Feeding OA significantly reduced the growth rate of broiler chicken. The reduction was observed from the first week onwards in OA-treated groups. Feed consumption and feed conversion also showed a diminishing...
متن کاملEffect 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...
متن کاملEffects of hen production cycle and egg weight on egg quality and composition, hatchability, duckling quality, and first-week body weight in Pekin ducks.
This study was conducted to determine the effect of hen production cycle (HPC) and the effect of egg weight (EW) at the same egg production level on egg quality, egg composition, hatchability, duckling quality, and first-week BW in Pekin ducks. For HPC, hatching eggs were obtained from different Pekin-duck breeder flocks, aged 31 wk for the first production cycle (HPC1) and 78 wk for the second...
متن کاملEffect of the Genetic Selection of Turkeys for Increased Body Weight and Egg Production on Immune and Physiological Responses1
Selection of poultry for fast growth rate is often accompanied by a reduction in specific immune responses or increased disease susceptibility. In this study, 17-wk-old male turkeys from each of four closed genetic lines, a randombred control (RBC) line and its subline (F) selected for increased 16-wk BW, and another RBC line and its subline (E) selected for increased egg production, were teste...
