Abstract

This study was conducted to determine the effects of the dam’s milk yield and composition on birth weight, 6-month, and 12-month live weight (LW) of Anatolian buffalo calves born in 2017 and 2018 years in Çorum province, Türkiye. Calving age had a significant impact on daily milk yield (DMY) (P=0.031), lactation milk yield (LMY) (P=0.048) and solids-not-fat (SNF) (P=0.034). DMY (P=0.022) and fat content (P=0.005) were affacted by calving season. Suckling period and calf sex had no significant impact (P>0.05) on DMY, LMY, fat content, and solids-not-fat (SNF) (P>0.05). The dam’s calving age had a significant impact on birth weight (P=0.029), except for 6-month and 12-month live weight (LW). Calving season affected 6-month (P=0.002) and 12-month LW (P=0.012) without birth weight. The suckling period and calf sex were not significantly affected on the birth weight, 6-month, and 12-month LWs (P>0.05). The highest 6-month LW (P=0.025) was determined in the calves of high DMY buffaloes (>6.50 kg). The DMY of the dam had no effect on the birth weight and 12-month LWs (P>0.05). The calves of buffaloes with the highest LMY (>1300 kg) were observed the highest birth weight (P=0.040) and 6-month LW (P=0.046). The dam’s fat and SNF content had no effect on the birth weight, 6-month, and 12-month LWs. To conclude; “higher milk yield resulted in higher birth weight” means that better dams give better calves, suggesting that buffalo keepers should feed buffalo cows sufficiently to get heavier calves at least.

母牛产奶量和牛奶成分对安纳托利亚水牛犊牛出生体重和生长性能的影响

本研究旨在确定母牛的产奶量和成分对2017年和2018年在土耳其乔伦省出生的安纳托利亚水牛犊牛的出生体重、6个月和12个月活重（LW）的影响。产犊年龄对日产奶量（DMY）（P=0.031）、泌乳期产奶量（LMY）（P=0.048）和固形物-非脂肪（SNF）（P=0.034）有显著影响。DMY（P=0.022）和脂肪含量（P=0.005）受到产犊季节的影响。哺乳期和犊牛性别对 DMY、LMY、脂肪含量和固形物-非脂肪（SNF）没有显著影响（P>0.05）。母牛的产犊年龄对出生体重有显著影响（P=0.029），但 6 个月和 12 个月活重（LW）除外。产犊季节对 6 个月活重（P=0.002）和 12 个月活重（P=0.012）有影响，但对出生体重无影响。哺乳期和犊牛性别对出生体重、6 个月和 12 个月活重的影响不明显（P>0.05）。高 DMY 水牛（大于 6.50 千克）的犊牛 6 个月净重最高（P=0.025）。母牛的 DMY 对犊牛的出生体重和 12 月龄体重没有影响（P>0.05）。观察发现，LMY最高（>1300 kg）的水牛犊牛出生体重（P=0.040）和6个月净重（P=0.046）最高。母牛的脂肪和 SNF 含量对出生体重、6 个月和 12 个月的产重没有影响。总之，"更高的产奶量导致更高的出生体重 "意味着更好的母牛能产更好的犊牛，这表明水牛饲养者应充分喂养水牛，至少能使犊牛更重。
