Abstract
|
|
|
Genetic diversity of Bachaur cattle- a draft breed of India bordering Nepal, was investigated by utilizing microsatellite markers. Forty seven random animals of the breed were typed with a set of 23 microsatellites proposed by the FAO for the biodiversities studies. All the microsatellites amplified well and exhibited polymorphism. The observed number of alleles
(No) per locus varied from 3 (ILSTS011) to 13 (ILSTS034) with the mean number of alleles 6.30 ± 2.16. Our results showed that this draft breed which is still relevant in its breeding tract due to socio-economic conditions possesses sufficient genetic variability as demonstrated by the values for the expected and observed mean heterozygosity (0.694 and 0.534,
respectively). Twelve microsa.tellite loci are in Hardy- Weinberg equilibrium and FIS shows higher value (0.228), suggesting heterozygote deficiency in the population. The results reflect the need for a conservation plan for this breed.
