Abstract

An investigation was carried out to study the effect of season, genotype, age of breeder hen and source of egg collection on fertility, hatchability and chick survivability at Palampur during July 2010 to August 2012. There was significant effect of season on the fertility (P<0.01). The highest average fertility was observed in winter (90.54±0.64%) followed by monsoon (86.74±1.45%) and summer (84.73±1.67%). The highest mean fertility was found in Native, followed by Native x Dahlem Red (DR) and Native x Rhode Island Red (RIR). The highest average fertility and hatchability were observed in 40-60 week age group followed by 26-40 week and 60 and above. The source of collection of egg also has significant effect on hatchability as well as fertility (p<0.01). Eggs collected from farmer's flock had lower fertility (81.06±1.33%) and hatchability (67.61±1.80%) when compared with fertility (88.27±0.88%) and hatchability (74.70±1.17%) of farm's eggs. The hatchability operation under sub temperate condition of the region can be effectively carried out throughout the year without much reduction in fertility and hatchability, although greater care and managemental precision must be exercised in winter season both during hatching as well as brooding in the region.

Abstract

Maize is one of the major ingredients of poultry feed and being a major Kharif crop in H.P., it is readily available in the area. But majority of the broiler poultry farmers in the region are using readymade feed. In the present study, the cost of feeding broilers was studied where in one group was fed weighed quantity of starter and finisher ration from 8-21 and 22-40 days of age respectively while the second group was fed grounded local maize plus booster ration in the ratio of 50:50 from 8-21 days and 60:40 from 22-40 days of age. Results revealed that the feed conversion ratio and weight gain was comparable among two groups but the cost offeeding per broiler was Rs 113.27 in readymade feed fed group while it was only Rs 99.75 in maize plus booster ration fed group. Thus, it may be concluded that feeding of maize plus booster ration to broiler chicks effectively reduced the cost of feeding per broiler and increase return per bird without any untoward impact on broiler performance.

Abstract

Wool yield data on first and second annual wool clips and cumulative yield over first two years on 588 German Angora rabbits of either sex, maintained at Angora Rabbit Breeding Farm, Kandwari, Palampur (HP) in sub­ temperate, mid­hill region of Himachal Pradesh at altitude of 1300 mts above MSL over a period of 8 years (2000 to 2007) were analysed to study the effect of year and season of kindling and sex of the animal on performance for these wool yield traits. All rabbits were farm bred progeny obtained during subsequent generation mating of a foundation stock (8 bucks and 32 does) of an improved imported strain of German Angora breed. The overall least squares means estimated were 594.22 ± 67.13 g, 591.82 ± 193.67 g and 1185.96 ± 202.96 g for first annual, second annual and cumulative wool yields respectively. The year of kindling effect was observed significant (P<0.01) on all wool production traits under study while seasonal influence was significant (P<0.05) for first annual wool clip only. The sex differences were observed statistically non­significant. From the results, it can be concluded that among different non­genetic factors, the period of kindling is the single largest effect influencing performance of German Angora rabbits for annual and cumulative wool production traits.
