Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    GENETIC STUDIES ON SOME ECONOMIC TRAITS IN RAMBOUILLET x GADDI (HIMTAL MERINO) CROSSBRED SHEEP UNDER SUBTEMPERATE CONDITIONS
    (CSKHPKV, Palampur, 2016-02) Thakur, Shalini; Thakur, Y.P.
    ABSTRACT A crossbred sheep population locally named as “Himtal Merino” with 75% Rambouillet inheritance have been evolved at Govt. Sheep Breeding Farm, Tal (Hamirpur) by crossing of Gaddi ewes with Rambouillet rams. Data on 1204 crossbred lambs for growth and wool production, 669 ewes for reproductive and 370 sheep for lifetime performance traits, progeny of 28 sires, were analysed by LSMLMW method using a fixed effect model to study mean performances and effect of some genetic and non-genetic factors on performance traits. The variance and co- variance components for genetic parameters were estimated by single trait animal model using WOMBAT software. The overall least squares means were 3.26±0.06, 16.11±0.03, 21.82±0.06 and 26.29±0.12 kg for lamb‟s weight at birth, 3, 6 and 12 months of age respectively, 141.44±0.18 g/day for pre weaning growth rate and 63.68±0.34 g/day during 3-6 months of age, 24.53±0.45 g/day during 6-12 months age and 36.64±0.38 g/day over 3-12 months of age post weaning body weight gain. The means were higher for HTM than R x G and R x RG lambs. Higher growth rate was achieved during pre weaning than post weaning stages. The mean age at first breeding and first lambing were 924.25±0.78 and 1070.51±0.48 days respectively. For wool production traits, the means for age at first shearing (AFS) was 184.62±0.14 days, shearing interval as 180.29±0.07 days, first and second annual greasy fleece were 1823.30±1.59 g and 2163.83±1.83 g respectively, second annual yield being higher than first. The mean longevity was 1210.72±26.39 days with productive life span of 945.84±26.39 days. The heritability for growth traits was low to medium being 0.19±0.05, 0.14±0.04, 0.20±0.05 and 0.06±0.03 for birth, 3, 6 and 12 months of age body weights. High heritability (0.62±0.01) was estimated for pre weaning body weight gain. For post weaning body weight gains, heritability were 0.14±0.04 for 3-6 months, 0.15± 0.04 for 6-12 months and 0.10±0.04 for 3-12 months of age. The heritability for various reproductive traits were low to moderate with estimates of 0.22±0.02, 0.02±0.10, 0.08±0.11, 0.07±0.10, 0.21±0.04, 0.31±0.06, 0.16±0.03, 0.18±0.05 for age at first breeding, age at first lambing, first lambing interval, second lambing interval, first service period, second service period, first gestation period and second gestation period respectively. For wool production traits, low heritability of 0.19±0.07 and 0.18±0.06 was estimated for age at first shearing and shearing interval and low to moderate heritability of 0.21±0.06, 0.14±0.04, 0.24±0.11, 0.23±0.09, 0.31±0.08 and 0.29±0.07 for fleece yield at first, second, third and fourth clips, first and second annual fleece yields respectively. Most genetic and phenotypic correlations among growth traits were positive and high. Positive genetic correlations were observed among various wool production traits and growth traits and wool production traits indicated scope for selection on basis of early expressed growth traits.
