“…The least-squares mean for first lactation milk yield was observed to be 1832.99 ± 42.43 kg in present investigation. Similar findings were reported by Rahumathulla et al, (1994) and Hussain et al, (2015) in Tharparkar cows. The effect of period of calving on FLMY was found to be non-significant.…”

“…The analysis of variance (Table 1) revealed that the effect of period of calving was significant (P ≤ 0.05) for first lactation length. Gahlot(1999) and Hussain et al, (2015) in Tharparkar cattle also observed significant effect of period of calving on FLL. The significant difference in FLL is probably due to different fodder availability and different managemental conditions in different periods.…”

“…The effect of period of calving was not in agreement with previous research [ 26 , 29 , 30 ] as they found it significant on FSP. Average FLMY in the Tharparkar was less in the present study than that of reported earlier (1,822.65±70.2 kg) [ 31 ]; however, higher than that of reported at 1,019±20 kg [ 32 ]; and similar to another report with 1,618±70 kg [ 33 ]. While the effect of season on FLMY was similar to our study, the effect of period on FLMY was unlike the previous results [ 32 , 33 ].…”

Objective: The present study was aimed primarily for estimating various genetic parameters (heritability, genetic correlations) of reproduction (age at first calving [AFC], first service period [FSP]); production (first lactation milk, solid-not fat, and fat yield) and lifetime traits (lifetime milk yield, productive life [PL], herd life [HL]) in Tharparkar cattle to check the association of reproduction traits with lifetime traits through two different methods (Frequentist and Bayesian) for comparative purpose.Methods: Animal breeding data of Tharparkar cattle (n = 964) collected from Livestock farm unit of ICAR-NDRI Karnal for the period 1990 through 2019 were analyzed using a Frequentist least squares maximum likelihood method (LSML; Harvey, 1990) and a multitrait Bayesian-Gibbs sampler approach (MTGSAM) for genetic correlations estimation of all the traits. Estimated breeding values of sires was obtained by BLUP and Bayesian analysis for the production traits.Results: Heritability estimates of most of the traits were medium to high with the LSML (0.20±0.44 to 0.49±0.71) and Bayesian approach (0.24±0.009 to 0.61±0.017), respectively. However, more reliable estimates were obtained using the Bayesian technique. A higher heritability estimate was obtained for AFC (0.61±0.017) followed by first lactation fat yield, first lactation solid-not fat yield, FSP, first lactation milk yield (FLMY), PL (0.60±0.013, 0.60±0.006, 0.57±0.024, 0.57±0.020, 0.42±0.025); while a lower estimate for HL (0.38±0.034) by MTGSAM approach. Genetic and phenotypic correlations were negative for AFC-PL, AFC-HL, FSP-PL, and FSP-HL (–0.59±0.19, –0.59±0.24, –0.38±0.101 and –0.34±0.076) by the multi-trait Bayesian analysis.Conclusion: Breed and traits of economic importance are important for selection decisions to ensure genetic gain in cattle breeding programs. Favourable genetic and phenotypic correlations of AFC with production and lifetime traits compared to that of FSP indicated better scope of AFC for indirect selection of life-time traits at an early age. This also indicated that the present Tharparkar cattle herd had sufficient genetic diversity through the selection of AFC for the improvement of first lactation production and lifetime traits.

“…Increased self grooming was associated with elevated cortisol concentrations Matamala et al (2021). It follows that periparturient cattle may demonstrate increased auto-grooming (Munksgaard and Simonsen, 1996;Kruk et al, 1998;Hussain et al, 2015) due to elevated cortisol level at approaching parturition. Increased time as well as frequency of self grooming in >90% pregnant Tharparkar cows (Fig 3 and 4) of either group at 12 h before calving is consistent with the above reports.…”

Background: The study was conducted to evaluate the effect of floor enrichment with rubber mattress of calving pen on prepartum calving behaviour of Tharparkar cow during the winter season. Methods: A total 28 Tharparkar cows were taken in study during winter season (November to March) and divided into two groups each contain 14 animals. One group placed in floor enriched with rubber mattress and other group kept on bare concrete floor calving pen. Preparturient behaviours like lying time, standing time, lying bout duration, number of lying bouts, rumination time ,rumination bouts, self grooming and frequency of self grooming were evaluated on -12 hr, -7th day, -14th day and -21st day prepartum for period of 12 hr in a day. Repeated Meausures ANOVA was used for the analysis of the data. Result: It was found that lying time, lying bout duration was significantly more in rubber mattress group as compare to concrete floor. However, 12 hr before parturition standing time was significantly high compare to any other observational day within the group. Similarly, rubber mattress had positive effect on rumination time, lying duration and self grooming frequency as compare to bare concrete floor. It was concluded that rubber mattress had beneficial effect in calving pen of Tharparkar cow during winter season due to its softness and insulating property. It provided comfort and warmth to the parturient cows. which was evident by increase in rumination time, more lying duration and reduced self grooming frequency.
