Research on artificial insemination technology in Hu sheep production
In order to fully utilize high-quality Hu sheep breeds,accelerate the expansion of good breeds,and improve the economic benefits of large-scale sheep farms,an artificial insemination experiment in Hu sheep was conducted in a Hu sheep breeding farm in Cangnan county in August 2023.Ninety ewes weighing approximately 45 kg were divided into three groups.Group 1 and group 2 consisted of 30 reserve ewes and 30 multiparous ewes,respectively,and treated with'estrus synchronization+artificial insemination',and group 3 was the control group having postpartum weaned 30 ewes and treated with'natural estrus+natural mating'.Three healthy rams were randomly placed into 3 groups,each of which having one ram.The first day of the experiment was day 0,early pregnancy diagnosis was performed using B-ultrasound at 45 d.The results showed that the conception rates in group 1,2,and 3 were 76.70%,86.70%and 60.00%,respectively.The average conception rates in group 1 and 2 were significantly higher than those in group 3(P<0.05),and the artificial insemination effect of multiparous ewes was better than that of reserve ewes,indicating that the artificial insemination technology scheme in this experiment achieved good results.
