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 کاملEffects of light intensity from photostimulation in four strains of commercial egg layers: 2. Egg production parameters.
The effects of light intensity (LI) from photostimulation to 45 wk of age on egg production parameters and egg size characteristics were examined in four layer strains. Floor housed pullets were raised in a light-tight facility from 1 d of age until housing in individually illuminated cages at 17 wk of age. At 17 wk of age, two white egg strains, ISA-White (ISA-W) and Shaver 2000 (S2000), and t...
متن کاملEffects of balanced dietary protein levels on egg production and egg quality parameters of individual commercial layers.
The effects of a series of balanced dietary protein levels on egg production and egg quality parameters of laying hens from 18 through 74 wk of age were investigated. One hundred forty-four pullets (Bovans) were randomly assigned to individual cages with separate feeders including 3 different protein level series of isocaloric diets. Diets were separated into 4 phases of 18-22, 23-32, 33-44, an...
متن کاملFuzzy modeling to predict chicken egg hatchability in commercial hatchery.
Experimental studies have shown that hatching rate depends, among other factors, on the main physical characteristics of the eggs. The physical parameters used in our work were egg weight, eggshell thickness, egg sphericity, and yolk per albumen ratio. The relationships of these parameters in the incubation process were modeled by Fuzzy logic. The rules of the Fuzzy modeling were based on the a...
متن کاملSeroprev Alence and Pathology of Egg Drop Syndrome (eds-76) in Commercial Chicken Layers
From September 1994 to April 1996, the aetiology of sudden decrease in egg production in commercial layer flocks was investigated. Clinical manifestations were recorded and the egg-shell quality was evaluated in 80 affected flocks. Serological screening was conducted twice at fortnightly intervals to record antibody titres against egg drop syndrome (EDS). Out of 80 flocks with lowered productio...
