“…Similar findings were obtained in different studies (Thiruvenkadan et al, 2009;Kul et al, 2017;Erdogan et al, 2021;Kaplan, 2021;Alkoyak and Öz, 2022). BW values (175.41 ± 2.06 kg) were found to be higher than the results of earlier research (Thiruvenkadan et al, 2009;Akhtar et al, 2012;Şekerden, 2014;Pandya et al, 2015;Kul et al, 2017;Yılmaz et al, 2017;Erdogan et al, 2021;Kaplan, 2021) for Murrah, Nili-Ravi, Surti, and Anatolian breeds, whereas higher values were reported by some studies (Shahin et al, 2010;Mendes Malhado et al, 2012;Vergara et al, 2012;Falleiro et al, 2013;Agudelo-Gómez et al, 2015;Shahjahan et al, 2017;El-den et al, 2020;Medrado et al, 2021).

Abstract. The body size and ultrasound carcass traits are related to the growth and muscling of animals. These characters promise future improvement through genetic selection in animal breeding. In breeding programs, knowing the (co)variance components serves to reveal the performance differences among animals and detection of suitable traits for selection. The research was carried out with 313 Anatolian buffalo calves born in 2019 at 36 farm operations. The least-square means for body weight (BW), wither height (WH), rump height (RH), body length (BL), chest width (CW), hip width (HW), chest circumference (CC), cannon-bone circumference (CBC), longissimus muscle area (LMA), longissimus muscle depth (LMD), and subcutaneous fat thickness (SFT) in yearling calves were 175.41 ± 2.06 kg, 108.35 ± 0.34, 111.85 ± 0.37, 103.74 ± 0.41, 33.93 ± 0.23, 30.56 ± 0.23, 135.18 ± 0.60, 15.69 ± 0.08 cm, 19.36 ± 0.45 cm2, 3.086 ± 0.028, and 0.655 ± 0.006 cm, respectively. The direct heritabilities for BW, WH, RH, BL, CW, HW, CC, CBC, LMA, LMD, and SFT were 0.334 ± 0.032, 0.483 ± 0.044, 0.473 ± 0.043, 0.441 ± 0.041, 0.364 ± 0.034, 0.432 ± 0.040, 0.435 ± 0.040, 0.226 ± 0.021, 0.0001 ± 0.000, 0.300 ± 0.026, and 0.539 ± 0.046, respectively. The genetic and phenotypic correlations predicted in this study ranged from 0.02 to 0.90. All the genetic and phenotypic correlations among body size and ultrasound carcass traits were significant (P<0.01), except for the genetic correlation between CW and HW. Some polymorphisms in PLAG1, NCAPG, LCORL, and HMGA2 genes were analyzed. Two single-nucleotide polymorphisms (SNPs) for PLAG1 and NCAPG genes were found to be monomorphic in this buffalo population. Meanwhile, the effects of two SNPs in the LCORL and HMGA2 genes were not significant but showed some tendencies in the aspects of least-square means. The results of the study indicated that the Anatolian buffaloes have the potential to improve in growth and muscling characteristics.

“…Estimates of genetic correlations between BWGW and WGW12 in buffaloes are also rare in the literature. The genetic correlations between body weights of buffaloes at various ages are moderate to high [19,24], presenting a behavior similar to that observed for BWGW and WGW12 for all the breeds studied here. Genetic correlations indicated that the selection for weight gains at younger ages leads to an increase in weight gains at 12 months, which allows producing more precocious buffalo animals.…”

The request for products of buffalo origin (beef and milk) has been growing throughout the years, and to meet this demand it is necessary to obtain animals with high levels of performance guaranteed through generations. Thus, it is of paramount importance to know the heritability of the desired traits in order to genetically improve the populations. The objective was to estimate the genetic parameters for weight gain from birth to weaning (BWGW) and from weaning to 12 months of age (WGW12) of Murrah (4675), Mediterranean (405), and Jaffarabadi (766) buffaloes raised in Brazil. Bayesian inference with the bi-trait model was used. The direct heritability in the Mediterranean and the Jaffarabadi breeds presented low to moderate estimates whereas the Murrah breed was medium for the two traits considered. Heritability estimates for maternal effect were low for BWGW and decreased with advancing age but remained present until 12 months of age. The genetic correlations found between all traits indicate that selection for increased weight gain at younger ages leads to increased weight gain at 12 months and it is thus possible to select at this age since the weight gains are highly correlated in all breeds.

“…However, similar estimates have been reported by Pareek and Narang (2014), Patil et al (2018) and Kumar et al (2022). In buffaloes, lower to higher heritability for milk yield have been reported by various researchers in different buffalo breeds (Aspilcueta-Borquis et al, 2010;Hossein-Zadeh, 2015;Malhado et al, 2012;Seno et al, 2010;Tonhati et al, 2008) which suggests there is sufficient additive genetic variation to respond to selective breeding.…”

The aim of this research was to assess genetic parameters for first lactation production and reproduction traits in Murrah buffaloes by employing additive and maternal effects. Data on pedigree and specific traits of 640 Murrah buffaloes were gathered from 1997 to 2020. These traits encompassed first lactation milk yield (FLMY), 305‐day first lactation milk yield (305FLMY), first lactation length (FLL), first lactation peak yield (FPY), first service period (FSP), first calving interval (FCI) and first dry period (FDP). Genetic evaluations employed six univariate animal models, accounting for both direct and maternal effects, facilitated by THRGIBBS1F90 and POSTGIBBSF90 programs. Fixed factors included in the analysis were period of calving, season of calving and age at first calving. The Bayesian estimates for direct heritability, derived from the most suitable model, were as follows: FLMY: 0.28 ± 0.01, 305FLMY: 0.30 ± 0.01, FLL: 0.19 ± 0.01, FPY: 0.18 ± 0.01, FSP: 0.12 ± 0.01, FCI: 0.14 ± 0.01 and FDP: 0.12 ± 0.01. Maternal effects were found significant, ranging from 5% to 10%, in first lactation traits under Model 2 and Model 5. Additionally, positive and significant genetic and phenotypic correlations were observed among the studied traits. In conclusion, selection based on 305‐day first lactation milk yield suggests potential for genetic enhancement in Murrah buffaloes, advocating its inclusion in breeding programmes to bolster early performance. Also, consideration of maternal influences is necessary for genetic progress of animals.
