“…The AFC trait was positively correlated with FCI, FLP, and FSP traits, whereas AFC was negatively correlated with FLMY and WFC traits at the genetic level. The positive magnitude of genetic correlation was also reported by Jain and Sadana (2000), Singh (2001) and Badran et al (2005) between AFC and FCI, Kumar (1998) and Singh (2001) between AFC and FLP, and Jain and Sadana (2000), Saha and Sadana (2000) and Badran et al (2005) between AFC and FSP traits. These results indicated that AFC can be used as a selection criterion for milk production.…”

“…Raheja (1992), Dutt and Taneja (1994), Dass and Sadana (2000) and Dutt et al (2001) for AFC and FLMY and Singh (1995) for WFC also reported similar estimates. However, the lower magnitude of heritability was reported by Khan et al (1996) for AFC and FLMY, Kuralkar and Raheja (1997) for AFC and FLMY, Kumar (1998) for AFC and WFC, Jain and Sadana (2000) for AFC and FLMY, Thevamanoharan et al (2000) for AFC and FLMY, Singh (2001) for AFC, FLMY, and WFC, and Thevamanoharan et al (2002) for AFC and FLMY traits. Tein and Tripathi (1990) reported higher estimates of heritability for AFC and WFC traits.…”

A study was conducted for studying the inheritance pattern of some first lactation traits in Murrah buffaloes. Data on 577 Murrah buffaloes maintained at the farms - Firozpur, Ambala, Jallandhar, Jhansi, Lucknow, Bareilly, Agra and Pantnagar spread over 34 years was used. The traits considered were age at first calving (AFC), first calving interval (FCI), first lactation milk yield (FLMY), first lactation period (FLP), weight at first calving (FCI) and first service period (FSP). The heritability estimates (h2Â±S.E) for AFC, FCI, FLMY, FLP, WFC and FSP traits were found to be 0.40Â±0.15, 0.14Â±0.10, 0.31Â±0.14, 0.23Â±0.12, 0.36Â±0.13 and 0.06Â±0.0, respectively. The genetic and phenotypic correlations revealed that selection for lower age at first calving and higher lactation milk yield can be used as a selection criterion for the genetic improvement in Murrah buffaloes.

“…On the contrary negligible genetic correlation between these two traits, considering three trait model, was reported by Jain and Sadana (2000) in Murrah buffalo. There was very low phenotypic correlation between FLMY and AFC.…”

“…The estimate of heritability for FSP was medium. Mantysaari (1989) reported low, while, Jain and Sadana (2000) reported near to zero heritability estimate for FSP in Finnish Ayrshire cattle and in Murrah buffalo, respectively. Low and negative genetic correlation was observed between FLMY and AFC.…”

were considered for the estimation of genetic parameters. Variance and covariance estimates of first lactation traits were obtained using restricted maximum likelihood technique (REML). When first lactation milk yield (FLMY), first lactation length (FLL) and average daily yield (ADY) traits were considered for REML analysis, the heritabilities were 0.184±0.146, 0.132±0.131 and 0.141±0.133, respectively. While, genetic and phenotypic correlations between them were medium to high except phenotypic correlations between FLL and ADY (-0.025). REML procedure considering FLMY, age at first calving (AFC) and first service period (FSP) combination exhibits heritabilities as 0.274±0.173, 0.506±0.233 and 0.274±0.172, respectively. Genetic correlations were -0.120±0.376, 0.225±0.423 and 0.365±0.331 between FLMY and AFC, FLMY and FSP, AFC and FSP, respectively. Phenotypic correlations were 0.057, 0.289 and 0.123, respectively. Considering all five traits REML combination heritabilities estimated were 0.238±0.162, 0.160±0.139, 0.136±0.132, 0.409±0.209 and 0.259±0.168 for FLMY, FLL, ADY, AFC and FSP, respectively. The genetic correlations were positive except FLMY and AFC. The phenotypic correlations were also positive except FLL and ADY, ADY and FSP. Almost all estimates were associated with high standard error.
