Parent Stock

The experiment was conducted to determine the effect of artificial insemination (AI) on different production parameter in Hubbard Classic Broiler breeder parent stock. A total number of 300 female and 30 male Hubbard Classic broiler breeder parent stock birds were used as experimental animals and parameter recorded are: Health condition and body weight of birds, % of Production, % Hatchability,% Uniformity, grade A chicks, mortality % , hatching egg % & effect of diluents use, birth weight of day old chick (DOC). Significant variation (p<0.01) was observed in number of hatched birds, % of hatchability, production of total no of Grade A chicks, total number of damaged chicks and average chick weight. In the study, hatchability (%), production (%), growth and puberty weight (g) were significantly higher during post insemination compared to pre insemination stage, where as mortality (%) and uniformity (%) were significantly lower in case of post insemination stage. Body weight and uniformity (%) of birds either both sexes were significantly (p<0.01) different in birds at pre insemination stage compared to the birds at insemination. To be mentioned that body weight of birds was negatively correlated to the uniformity. Finally it could be concluded that AI may be better in all the parameters observed in this study than natural mating. So, AI can be practiced in Hubbard Classic broiler breeder parent stock.J.

Different Sources

To date commercial broiler breeders have focused primarily on increasing early growth rate in selection programmes aimed at improving overall production efficiency. In commercial programmes, early growth rate is simplified to a single body weight measure taken at a fixed age during the growth phase approaching common slaughter weights. Most recent selection studies report heritabilities from experimental populations that are at best, synthesised from crossing modern broiler material from several different sources (Leenstra et al, 1986; Wang et al, 1991). Therefore, such populations are likely to exhibit greater heterozygosity than many commercial lines which have undergone many generations of intense selection in closed populations. This paper reports heritabilities estimated using both least squares and derivative-free maximum likelihood techniques for data from a commercial breeder dam line which has remained closed since its inception in 1975.
