摘要
本研究比较了利穆赞(L)和夏洛来(C)小母牛的生育和分娩参数,以确定最适合牛肉生产的品种。在多根农场,共有234头9-11个月的匈牙利产L型和76头C型小母牛在标准化的饲养和饲养条件下进行管理。根据分娩时间进行分类(日:07:00-19:00;夜)和季节(冷、凉、热)。采用方差分析(ANOVA)和卡方检验(Chi-square)进行统计学分析。结果表明,C型母牛的受精率显著高于对照组(C: 3.39±0.22,L: 2.32±0.10,P 2 = 10.4244, P 2 = 10.4244)
Fertility and parturition parameters in beef type heifers.
This study compared fertility and parturition parameters in Limousin (L) and Charolais (C) heifers to identify the breed most suitable for beef production. A total of 234 L and 76 C Hungarian-origin heifers, aged 9-11 months, were managed under standardized housing and feeding conditions at Dogan Farm. Parturitions were categorized based on the time of day (day: 07:00-19:00; night) and season (cold, cool, hot). Statistical analyses were conducted using ANOVA and Chi-square tests Results showed that C heifers required significantly more inseminations to conceive (C: 3.39 ± 0.22, L: 2.32 ± 0.10, P < 0.0001), indicating lower reproductive efficiency. Additionally, C calves were significantly heavier at birth than L calves (C: 46.1 ± 0.8 kg, L: 40.2 ± 0.3 kg, P < 0.0001), with male calves being generally heavier than females (M: 43.7 ± 0.5 kg, F: 39.5 ± 0.3 kg, P < 0.0001). The incidence of dystocia was higher in C heifers (63.16%) compared to L heifers (41.88%), while L heifers experienced greater parturition ease (58.12% vs. 36.84%; X2 = 10.4244, P < 0.0054).
