dc.description.abstractEstimation of genetic parameters is important to determine the selection criterion and future breeding strategies. Jersey × Red Sindhi crosses are milk-purpose breeds of cattle and are popular among farmers for their high milk yield and efficient reproduction. The term “repeatability” refers to an animal’s likelihood of performing similarly to or better than the herd average in her next lactation than she did in her previous lactation. It’s usually calculated as an intra-herd correlation or a correlation between recordings from the same animal over multiple lactations. To maximize the profitability of dairy crossbred cattle, getting a better understanding of the factors that influence reproduction is critical. Skilled people raised and cared for the animals in identical feeding and management conditions. Calving interval (CI), service period (SP), dry period (DP), and days- open were the reproductive features investigated. The data revealed that the repeatability (r) with standard error (SE) for the calving interval (0.60± 0.71), service period (0.20, 0.140), dry period (0.14, ± 0.33) and days-open (0.94 0.14), had moderate repeatability. The calving interval, service period with low repeatability, dry period, and days open with high repeatability are all variables to consider.en_US
