Baggara inekleri süt üretimi süt bileşimi parite sırası üreme performansı Sudan.
This study was conducted to evaluate the effect of parity on milk yield and milk chemical composition and calving interval of Baggara cattle as effected by parity. Forty eight cows were selected from the herd of Baggara cattle. The cows were weighed and divided into four groups, each group comprised of (12) cows according to parity order, first, second, third and fourth parities. All cows were raised on natural grazing.The results revealed that parity order significantly (P≤0.05) affected daily, monthly and total milk yields. Milk production increased with advance parity. High (P≤0.05) milk yield, monthly and daily milk scored by 3rd parities as 668.47 kg, 133.73kg and 4.49kg, respectively. The results showed that there were significant differences (P≤0.05) between different parities for the milk composition during the first and third month of lactation period, with high fat percentages in the first month for 2nd parities (6.21) and 3rd parities (6.26) in 3rd month of lactation. The results indicated that calving, days to first estrus and days to conceive were significantly (P≤0.05) affected by parity number. Shorter days to show estrus was obtained by primiparous cows (56.19 ±8.72 days), also Days to conceive exerted significantly (P≤0.05) effected parity order. The results also showed a significant difference (P≤0.05) between different parities order for calving interval, that short day of calving interval scored by primiparous parities (10.04 months) and long days by 4th parities (13.17 month).In conclusion, Baggara cows that is depended on natural grazing reached its peak milk production in third parities with considered that the main purpose of these animals for meat production.
