Dissertation note | Poultry industry of Pakistan contributes a large segment to the national economy with an investment of more than 70 billions of rupees and has become the second largest industry after textile in Pakistan. The present project is designed to study the comparative hatching traits of different broiler strains. There are many commercial poultry companies that rear parent stocks consisting of different broiler parent strains of Hubbard, Hybro, Starbro, Arbor Acres. This sector is presently showing an annual growth rate of about 10-15 percent per annum and playing a vital role in narrowing down the gap between supply and requirement of animal protein foods. The present project is designed to study the comparative hatching traits of different broiler strains Hubbard, Hybro, Starbro, Arbor Acres. A total of 600 eggs comprising 150 each of the 4 broiler breeder strains viz. Hubbard, Hybro, Starbro and Arbor acres were purchased from local companies maintaining parent breeder flocks. These eggs were divided into three replicates having 50 eggs of each. All the eggs were examined on the basis of their size, shape and shell texture for the selection of settable eggs in each replicate. All eggs were weighed and coded and 3 eggs from each replicate were taken for measuring the egg quality characteristics before setting in the setter part of the incubator for the first 18 days. On day 19 all eggs were transferred to the hatcher room. Prior to shift eggs to the hatcher, all eggs were candled to check the fertility. Chicks were collected after 21 days from hatcher. The parameter such as, egg Weight, shell weight, shell thickness, albumen Weight, albumen height, yolk colour, yolk height, yolk diameter, yolk weight, yolk index, meat spot, blood spot, hatchability percentage, chick weight, infertility percentage, dead in germ percentage, dead in shell percentage were studied. The result of present study showed that, the mean egg weight indicated significant differences among different broiler strains. The maximum mean egg weight was recorded in Hubbard strain (68.5 gm ± 4.7).The mean shell weight showed significant difference among different broiler strains. The mean shell thickness showed non-significant difference among different broiler strains. The mean yolk colour, yolk diameter, yolk weight showed significant difference (p Based on the finding of this study it may be concluded that the egg quality characteristics like egg weight, shell weight, yolk colour, yolk weight, yolk diameter, albumin weight, albumin height, meat and blood spot percentage have significant differences among different broiler strains. The shell thickness, yolk index, yolk height non-significant difference among four different broiler strains. The Hubbard strain had maximum egg weight, yolk weight, yolk height, albumen height, in comparison to all other three strains. The results with regard to Hatchability traits like chick weight, hatchability percentage, infertility percentage, dead in germ percentage, dead in shell percentage have significant difference among different broiler strains. The Hubbard strain had maximum hatchability percentage and chick weight in comparison to all other three strains. On the basis of this study it may concluded that Hubbard strain have better results as compared to Arbor Acre, Hybro, Starbro strains. |
