“…Understanding the production and reproduction potential along with their A c c e p t e d A r t i c l e inter-relationship is needed to formulate strategies in breeding programs in domestic animals, including buffalo [18,19,7]. Though attempts have been made to estimate the heritability, genetic and phenotypic correlations of the economic traits in buffalo [20,7,12]. Further scope exist to analyse the inter-relationship of production and reproduction traits in buffaloes.…”

“…Highly heritable traits can be used with great efficiency for genetic improvement through progeny testing as well as other genetic improvement programs. Thus, selection of animals based on the performance of the economically important traits having high heritability needs to be considered for overall improvement in lifetime productivity through correlated response [ 7 , 12 ].…”

“…Likewise, suitability of breeding animals, including buffaloes, in an organized herd is primarily determined by its productive and reproductive efficiency [ 9 ]. First lactation traits are representative of subsequent lactation performance as these are highly inter-correlated both in cattle [ 10 , 11 ] and buffaloes [ 7 , 12 ]. Highly heritable traits can be used with great efficiency for genetic improvement through progeny testing as well as other genetic improvement programs.…”

Objective: This study was conducted to estimate the association of age at first calving with first lactation traits as well as lifetime performance traits in Murrah buffaloes.Methods: Data on first lactation and life time performance of Murrah buffaloes (n=679), maintained at ICAR-CIRB, Hisar, India during the period 1983 to 2017, were deduced to calculate heritability estimates, genetic and phenotypic correlation of different first lactation and lifetime traits. The univariate animal model was fitted to estimate variance components and heritability separately for each trait, while bivariate animal models were set to estimate genetic and phenotypic correlations between traits under study.Results: The heritability was high for First Peak Milk Yield (FPY, 0.64±0.08), moderate for Age at First Calving (AFC, 0.48±0.07) and breeding efficiency (BE 0.39±0.09). High genetic correlations of FLTMY (First Lactation Total Milk Yield) with FLSMY (First Lactation Standard (305 days or less) Milk Yield), FPY (First Peak Milk Yield) and FLL (First Lactation Length) was seen. Likewise, genetic correlation of AFC was positive with traits viz. FLTMY, FLL, FDP (First Dry Period), FSP (First Service Period), FCI (First Calving Interval), HL (Herd Life) and PD (Productive Days). Significant phenotypic correlation of FLTMY was observed with traits viz. HL (Herd Life), PL (Productive Life), PD, Total LTMY (Total Lifetime Milk Yield), Standard LTMY (Standard Lifetime Milk Yield). Moreover, positive genetic and phenotypic correlation of FPY was observed with HL, PL, PD, Total LTMY and Standard LTMY.Conclusion: This study reports that age at first calving had positive genetic correlation with FDP, FSP, FCI and UD (Unproductive Days) while, negative association of AFC was observed with FLSMY, PL, Total LTMY, Standard LTMY and BE. This suggests that reduction of age at first calving would results in improvement of lifetime performance traits.

“…Our findings confirmed two existing notions about the Indian buffaloes. First, it has been traditionally believed that the Mehsana breed is of the Murrah and Surti lineage ( Patel et al, 2017 ; Sathwara et al, 2020 ). The maximum-likelihood phylogram constructed using Treemix in our study showed the Mehsana and Surti emerging from the same node in the phylogenetic tree, with introgression of the Murrah germplasm into the Mehsana, which supports the anecdotal knowledge about this breed.…”

Comparative Signatures of Selection Analyses Identify Loci Under Positive Selection in the Murrah Buffalo of India

et al. 2021

India is home to a large and diverse buffalo population. The Murrah breed of North India is known for its milk production, and it has been used in breeding programs in several countries. Selection signature analysis yield valuable information about how the natural and artificial selective pressures have shaped the genomic landscape of modern-day livestock species. Genotype information was generated on six buffalo breeds of India, namely, Murrah, Bhadawari, Mehsana, Pandharpuri, Surti, and Toda using ddRAD sequencing protocol. Initially, the genotypes were used to carry out population diversity and structure analysis among the six breeds, followed by pair-wise comparisons of Murrah with the other five breeds through XP-EHH and FST methodologies to identify regions under selection in Murrah. Admixture results showed significant levels of Murrah inheritance in all the breeds except Pandharpuri. The selection signature analysis revealed six regions in Murrah, which were identified in more than one pair-wise comparison through both XP-EHH and FST analyses. The significant regions overlapped with QTLs for milk production, immunity, and body development traits. Genes present in these regions included SLC37A1, PDE9A, PPBP, CXCL6, RASSF6, AFM, AFP, ALB, ANKRD17, CNTNAP2, GPC5, MYLK3, and GPT2. These genes emerged as candidates for future polymorphism studies of adaptability and performance traits in buffaloes. The results also suggested ddRAD sequencing as a useful cost-effective alternative for whole-genome sequencing to carry out diversity analysis and discover selection signatures in Indian buffalo breeds.
