Effects of Calving Age and Calf Sex on Colostrum Composition and Its Changes After Calving in Anatolian Buffaloes
Öz
Objective: This study aims to investigate the changes in colostrum during the first 72 h after birth and to elucidate the impact of calving age and calf sex in Anatolian buffaloes.
Materials and Methods: The study used colostrum samples from 25 newly calved Anatolian buffalos raised under similar farm conditions. The samples were collected at the first milking after calving (T0), 24 h (T24), 48 h (T48), and 72 h (T72) after calving during the summer season. The postpartum period, calving age, and calf sex were considered as non-genetic factors.
Results: The first milking colostrum weight, fat, solids-not-fat (SNF), protein, and lactose content were determined as 2.95±0.21 kg, 7.96±0.45%, 17.5±1.63%, 14.5±1.45% and 2.58±0.24%, respectively. Fat, SNF, and protein were significantly higher at T0. Colostrum weight was the lowest at T0 and T24, gradually increasing at T48 and T72 (P<0.05). Lactose did not change statistically in the postpartum period (P>0.05). The calving age and calf sex did not statically affect colostrum weight, fat, SNF, protein, and lactose content (P>0.05).
Conclusion: In conclusion, the composition of buffalo colostrum showed significant changes in the postpartum period, especially after the first milking. Therefore, providing high-quality colostrum as soon as possible is recommended for calf health.
