Evaluation of productive and reproductive performances for Saanen×native and native goats in Kerman province

The purpose of this project is to investigate the characteristics of birth weight, three-month weight, weight gain from birth to three months, maturity weight and milk production of female goats during the years 2018 to 2022 in Kerman province, related to native goats (BB) and their hybrids with the Saanen breed, respectively,with 50 (S1 B), 75 (S2B) and 87.5 (S3B) percent of the Saanen breed gene. A number of 9 herds selected in Kerman province. The total number of female goats were 2089, of which 1909 were fertile and 2584 goats were born. Data storage, editing, and preparation were performed using Excel 2013 software. After editing and preparing the recorded information, the effect of fixed factors on variables and data analysis was performed using the Spss software. Birth weight, milk weight, and daily weight gain from birth to milk intake in crossbred kids were higher than in purebred kids. Crossbred goats had a higher milk production weight than native goats. In native goats, a fertility rate of 85% was obtained, while in those inseminated with Saanen breed, the fertility rate was 92%. The weaning rate in those inseminated with Saanen breed was higher than in native goats (137% vs. 111%). Also, the reproductive ability in those inseminated with Saanen breed was higher.
