“…As there was no report on FSP in Deoni cattle, comparison was made with pooled service period. The FSP estimated was similar to the pooled service period of previous studies as 184.2 ± 4.6 (Deshpande et al, 1977d) and 170.0± 7.0 days (Singh et al, 2002). Higher CV value for FSP in the present study revealed large scale of variation in the FSP of Deoni cattle.…”

“…The mean age at first calving is higher than the previous report in this breed (38.73 ± 0.73 months) by Das et al, (2011). However, the estimated mean AFC in the present study was lower than the previous reports on Deoni cattle reported by Deshpande et al, (1977a) and Singh et al (2002). Estimated CV value of the studied population indicated higher variation of AFC than the value (11.2 per cent) reported by Deshpande et al, (1977a) in the same breed.…”

“…The average annual rainfall in these areas varies from 736 to 919 mm. Based on the morphological characters; the animals are classified into 3 types i.e Balankya (pure white), Waghya (white and black Spots on the body) and Wannera (animals with complete white Body and black face) (Singh et al, 2002). This breed is hardy and well adapted for tropical draught prone areas (Das et al, 2011).…”

The present study was carried out in Deoni, the dual purpose cattle breed of Southern India, maintained at NDRI herd, SRS, Bengaluru. Mean phenotypic performances for the traits of age at first calving (AFC), first service period (FSP), first lactation milk yield (FLMY) and first lactation length (FLL) were estimated as 42.90 ± 0.49 months, 179.00 ± 6.3 days, 643.08 ± 25.16 kg and 178.24 ± 4.41 days respectively. Significant effect of parity was found on AFC and FSP. Effect of period of birth, period of calving and season of calving was found to be significant on FSP. Significant effect of period of birth, period of calving, classes of AFC and FLL were found on FLMY. The heritability of first lactation milk yield was estimated as 0.38 ± 0.29. Phenotypic correlation of FLMY with FLL (0.88 ± 0.02) was found to be highly significant (p<0.01).

“…In earlier studies of Indian native cattle, the major focus was on assessment of morphological parameters and information gained from local sources (Nivsarkar et al 2000;Joshi et al 2001;Singh et al 2002;Gaur et al 2003;Karthickeyan et al 2006). Recently, assessment of genetic diversity and delineation of the genetic structure of cattle breeds have become a major concern, as some of the important populations and breeds are either declining or breed characters are being diluted under the present production system.…”

Genetic Diversity and Structure of Two Prominent Zebu Cattle Breeds Adapted to the Arid Region of India Inferred from Microsatellite Polymorphism

et al. 2008

This study aims to assess the genetic diversity and population structure of two major zebu dairy breeds (Tharparkar and Rathi) adapted to the arid region of Rajasthan state of India. Various variability estimates indicate the existence of sufficient within-breed genetic diversity. Mean estimates of F-statistics are significantly different from zero: F (IS) = 0.112 +/- 0.029, F (IT) = 0.169 +/- 0.033, F (ST) = 0.065 +/- 0.017. The overall positive value of F (IS) (0.112) and an F (IT) value (0.169) that is more than the F (ST) (0.065) indicate departure from random mating. The drift-based estimates reflect a moderate yet significant level of breed differentiation between the Tharparkar and Rathi breeds. The evaluation of an exact test, showing that allele frequencies across all the loci differed significantly, supports the population differentiation. This is paralleled by the outcome of neighbor-joining clustering based on allele-sharing distance measures. The allocation of a high percentage of individuals (95.7%) to their population of origin and correspondence analysis further substantiates the existence of a cohesive genetic structure in both the breeds.

“…Over the years, categorization of these cattle breeds has often been based on morphological data and information gained from the local breed keepers. 1,[4][5][6][7] Hence, an effort to deduce the genetic structure among the Indian native cattle breeds becomes pertinent for the development of future management strategies. For this purpose, microsatellites markers previously exploited for diversity studies in cattle populations from Africa, Europe, and Asia [8][9][10][11][12][13][14] are utilized herein to characterize Indian native cattle breeds.…”

The present study aims to understand the existing genetic diversity and structure of six native cattle breeds (Rathi, Tharparkar, Nagori, Mewati, Gir, and Kankrej) adapted to the north-western arid and semi-arid region of India based on microsatellite loci. Various diversity estimates, mean number of alleles (12.84); effective number of alleles (5.02); gene diversity (0.769), and observed heterozygosity (0.667) reflected the existence of substantial within-breed diversity in all the investigated cattle breeds. Mean estimates of F-statistics: F(IT) = 0.144 ± 0.023, F(IS) = 0.071 ± 0.021, and F(ST) = 0.078 ± 0.014 were significantly different from zero (P < 0.05). The interbreed relationships indicated moderate level of breed differentiation between the six cattle breeds with least differentiation between Kankrej-Mewati pair. The phylogeny structuring further supported close grouping of Kankrej and Mewati breeds. Correspondence analysis plotted Rathi, Tharparkar, and Gir individuals into three separate areas of multivariate space; whereas, Kankrej, Mewati, and Nagori cattle showed low breed specific clustering. This reflected the existence of discrete genetic structure for Tharparkar, Rathi, and Gir, the prominent dairy breeds of the region; whereas, admixture was observed for Kankrej, Mewati, and Nagori individuals.
