    CHARACTERIZATION OF LOCAL INDIGENOUS CATTLE OF HIMACHAL PRADESH
    (CSKHPKV, Palampur, 2012-07) Verma, Deepak; Katoch, Sanjeet
    ABSTRACT Morphometric and genetic characterization of native, non-descript hill cattle popularly called ‘Pahari‘ cattle of Himachal Pradesh was carried out with the objective of its characterization as distinct cattle type and to study the genetic diversity in the existing population. Morphological and biometrical observations were recorded on 468 (202 males and 265 females) true-to-type hill cattle of different sex and age groups at 20 villages across 3 districts/regions in the mid hill and high hill region of the state, which is considered to be the true breeding tract of these cattle. The analysis of data revealed black (34.98%) as the main coat color followed by black brown (23.82%), brown (16.37%), reddish and reddish brown (10.92%), black with white patches (10.67%) and other mixed type (3.22%). The prominent color for muzzle (92.30%), hooves (96.52%), horns (97.23%) and tail switch (87.89%) was also black. The least squares means for body weight and different body measurements viz, body length, height at hump, chest girth, abdominal girth, face length, face width, ear length, horn length, neck length, neck width, fore limb length, hind limb length, tail length and tail length with switch were 158.73±3.37kg, 101.11±0.60, 97.12±0.49, 136.83±1.18, 158.55±1.33, 38.64±0.24, 16.40±0.11, 17.28±0.13, 12.12±0.41, 31.14±0.28, 28.95±0.25, 26.59±0.12, 38.45±0.23, 66.69±0.58 and 81.72±0.78 cm for adult females and 170.64±6.25 kg, 105.03±1.12, 103.34±0.87, 139.42±1.73, 160.83±1.61, 40.79±0.35, 18.30±0.71, 18.52±0.18, 19.21±0.91, 32.45±0.43, 31.59±0.42, 27.14±0.18, 39.21±0.39, 70.18±1.06 and 86.70±1.25 cm, respectively, for the adult males of hill cattle. The age and sex effects were observed significant for all the morphometric characteristics recorded. The location effect was observed non-significant suggesting that the animals across the entire breeding tract are of similar type. Molecular data generated by using FAO recommended bovine specific eighteen microsatellite markers was utilized to assess the existing genetic diversity based on sixty eight blood samples collected from randomly selected genetically unrelated animals from different locations. The mean observed and effective number of alleles was found to be 6.77±0.51 and 4.35±0.28, respectively. The average observed and expected heterozygosity was 0.87±0.03 and 0.76±0.01, suggesting random mating in hill cattle. The allele diversity and gene diversity values imply a substantial amount of genetic variability in hill cattle population. High PIC value (72%) suggests that the markers used are polymorphic and informative. Population inbreeding estimates (Fis=-0.15) indicated the absence of inbreeding in the population studied
