Abstract:
A study was undertaken to assess the effect of egg quality traits on the fertility and hatchability of Vanaraja Parents maintained in the poultry farm of the Poultry seed project of College of Veterinary Science and Animal Husbandry, Anjora, Durg (Chhattisgarh). A total of 150 numbers of eggs from each pen were selected for setting in a single-stage incubator for 48^th, 49^th, 52^nd, and 55^th week. Eggs were grouped and divided into three groups, i.e., below average, average, and above-average, according to their weight and shape index. Eggs were candled twice during incubation, i.e., on the 7th and 18th days. Fertility percent, hatchability percent on TES (total egg set basis), and FES (fertile egg set basis) calculated. The findings have shown that the highest fertility rate observed for average (53 – 61g) egg weight group were 90.12 %. However, significantly (P<0.01) highest overall hatchability on Fertile Egg Set (FES) basis was observed in the average group that is 89.22%. On the basis of their shape index, there is a significantly highest (P<0.01) fertility rate was observed in the average group that is 97.47%. The average hatchability on the Total Egg Set (TES) basis irrespective of different ages of the eggs of the average group (81.75%) was highly significant (P<0.01). And the average hatchability on the Fertile Egg Set (FES) basis irrespective of different ages of the eggs of average group 89.37% was highly significant (P<0.01). The results indicate that Vanaraja eggs having a normal oval shape and rounded shape hatch better as compared to the cylindrical eggs.
