“…Season of recording significantly affected the TDY with higher yield during the summer season as Gir animals are well adapted to the hot summer months. Fat, SNF and TS content of milk observed for Gir cattle in the present study were in accordance with the results obtained by Araújo et al (2018), Gajbhiye et al (2019) and Dora et al (2020).…”

“…In the present study, season and stage of lactation did not influence the milk composition traits while earlier studies (Gajbhiye et al 2019) reported significant effect of season and stage of lactation on milk constituent traits. Uniform plane of nutrition in the intensive management system followed in the farm could be the probable reason for absence of differences between season and stage of lactation.…”

Test day milk yield records (5130), milk production and milk composition traits from 19 lactations of Gir cows collected for two years (2019 and 2020) were used to understand the performance of Gir breed in hot and humid conditions of Tamil Nadu. Different lactation curve models were used for modelling test day records and model diagnostics like adjusted R-square, BIC and RMSE were used to obtain the model of best fit. The mean test day yield, fat per cent, SNF (%), total milk yield, peak yield, days to attain peak yield and calving interval observed were 5.78 kg, 5.05%, 7.65%, 1507 kg, 9.23 kg, 46.5 days and 447 days respectively. Ali and Shaeffer model offered the best fit for lactation curve in Gir cows. Mahadevan method and Gamma function were used to calculate the persistency of milk yield which was obtained as 1.33 and 6.348 respectively. Results of the study indicated that Gir cattle were able to adapt themselves through maintenance of reproductive traits comparable with that of the native tract but the new humid environment has caused a slight decrease in the performance of milk production traits.

“…An examination of the late stages of lactation in Holstein Friesian cross cows by Shibru et al, (2019) found no significant differences in fat percentage but a substantial difference in protein %. Gajbhiye et al, (2019) reported increased fat, SNF along with protein in later lactation stages in Gir cows. Shuiep et al, (2016) stated significant impacts of lactation stage on SNF, fatas well as lactose and reported higher fat (Vanbergue et al, 2017).…”

Background: The current study had been conducted to understand the impact of breed as well as season and stage of lactation on various milk constituents viz. freezing point, SNF, pH, lactose, protein, fat and electric conductivity of Sahiwal and Kankrej cows maintained at LRS”Livestock Research Station”, College of Veterinary and Animal Science, RAJUVAS, Bikaner, Rajasthan. Methods: Milk samples from 45 each Sahiwal and Kankrej cows were collected and analyzed for milk composition parameters. Data have been classified as per breed along with season and stage of lactation. Result: The analysis of variance for breed demonstrated highly significant impacts of fat and SNF whereas non-significant effect was found on pH, freezing point, lactose and protein.The analysis of variance demonstrated highly significant (P less than 0.01) impact of season on fat, SNF, freezing point and significant effect on protein whereas non-significant effect on lactose, pH and Electric conductivity in Kankrej cattle however highly significant (P less than 0.01) effect was found on fat in Sahiwal cattle.The analysis of variance presented significant (P less than 0.05) effect of lactation stage on fat and Protein in Sahiwal cattle whereas on fat and SNF in Kankrej cattle.
