Sheep Sex Control Technology Research

In this study, intra-abdominal endoscopic technology, the development of Chinese herbal medicine will be injected into fluid of control uterine horn sheep, in the time set by artificial Insemination, so as to achieve gender control on sheep. This study is divided into four experiments.Experiments one:Wusu in Xinjiang sheep breeding farms. Choice of 30 ewes of Kazakhstan, controlled by the capsule of 3ml / tablets, 4ml / beads and 5ml / tablets dose diluted to normal saline diluent, divided into 3 groups, the use of laparoscopy to the uterine fluid injection 2ml of control, the experiment was to explore a variety of concentrations of control ewes capsule on the role of sex control. the mother lamb was 57.1%, more suitable for the test. Experimental notes that control into the uterine fluid of the large dose, would result in excessive acidity of the uterus, causing part of the production of fetal malformation.Experiments two:Qinghai haixi Tianjun County Rural Health Grid for four homes. Choice of 60 high altitude Tibetan sheep, using 5% arginine and 10% of the Portuguese-controlled capsule dilution and 5% arginine alone divided into 3 groups, respectively, to the use of laparoscopic uterine fluid injection 1ml of control. The results showed that three of the conception rate of control fluid had no significant effect. Which glucose diluted with 10% of control of control capsules mother on the rate of production with the control group (71.4% VS53.3%) significant difference (P <0.01).Experiments Three:NeiMeng Chifeng City in Inner Mongolia, Germany and the United States companies. Select German Mutton Merino 60, using 5% arginine and 10% of the Portuguese-controlled capsule dilution and 5% arginine alone were divided into 3 groups, the use of laparoscopic uterine injection to 1ml of control solution.. Of which 10% glucose diluted control of the capsule on the middle of the mother charged with the control group rate (75% VS52.9%) compared with significant difference (P <0.01).Experiments four:1, the application of B-controlled trial in sex sheep breeding estrus after 30d, 60d of early pregnancy diagnosis in sheep, results show that 30d after breeding diagnostic accuracy was 77.9%, 60d after breeding diagnostic accuracy was 99.2%.2, the application of B-type ultrasonic diagnosis in estrus after breeding 35d-45d and 45d-60d to different standards at different times of the pregnancy test test test sheep for Germany and the United States company, Inner Mongolia Neimeng test test sheep in groupâ…¢. The optimum time for diagnosis of pregnancy after mating estrus about 45d.
