Development of sustainable performance index based on production, reproduction, health and longevity for genetic improvement of Sahiwal cattle

Background: Sahiwal is an outstanding milch breed of cattle originated from the Sahiwal area, Montgomery district of Punjab in Pakistan. Performance evaluation of this breed in the high humid condition of north-east India is very much limited. Assam Agricultural University is maintaining a pure herd of Sahiwal cattle in the College of Veterinary Science, Khanapara since August 2017 to conserve, propagate and bring about genetic improvement of this breed.Methods: The study was carried out in Sahiwal cattle farm, College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati by utilizing 25 numbers of Sahiwal calves. Least squares analysis of variance technique (1975) was undertaken to analyze the body weights of calves at monthly intervals up to six months of age. Result: Overall mean for body weights of calves were found as 26.96 ± 0.27 kg, 32.03 ± 0.47 kg, 37.03 ± 0.62 kg, 42.91 ± 0.76 kg, 48.45 ± 0.77 kg, 55.22 ± 0.77 kg, and 62.08 ± 0.88 kg at the day of birth, 1st month, 2nd month, 3rd month, 4th month, 5th month and 6th month respectively. Analysis of variance revealed that the bodyweight of male calves was significantly heavier than that of the female calves ( less than 0.05).

The present study was undertaken with the objectives of molecular characterization and detection of genetic polymorphisms in the HSPB6 gene of Sahiwal cattle. A total of 100 Sahiwal cattle maintained at LRC, NDRI, Karnal (Haryana) were included in the study. HSPB6 gene has been mapped on Bos taurus autosome 18 (BTA 18) and spans nearly 2620 bp comprising 3 exons and 2 introns. Four sets of forward and reverse gene-specific oligonucleotide primers of HSPB6 gene were designed using Primer3 software and amplicon size of 529 bp, 460 bp, 670 bp and 502 bp were ascertained. On the basis of comparative sequence analysis, total three polymorphic loci (SNPs) were detected at locus G436A, A2152G and A2417T in HSPB6 gene as compare to Bos taurus (NCBI GenBank AC_000175.1). Out of these three SNPs, two (A2152G & A2417T) were found in 3′-UTR region and third one (G436A) was detected in intronic region 1. However, monomorphic pattern was found in exon 2 of HSPB6 gene in Sahiwal cattle. Further research need be directed to find out the association of allelic variants in major heat shock protein genes to establish markers for the future genetic improvement of livestock through marker assisted selection.
