摘要
目的观察分析食蟹猴分娩行为,建立食蟹猴分娩发生的判定标准,进而结合兽医助产以提高食蟹猴活产率。方法通过对2017—2021年112只孕期140 d以上的围产期食蟹猴的监控视频进行回溯分析,观察记录分娩时食蟹猴的主要行为学表现,包括努责、摸舔产道、趴卧或躺卧、身体辗转和翻滚等行为。在此基础上建立分娩相关的行为指标的权重,详尽分析30只食蟹猴围产期的行为表现,以进行分娩判定。结果30只食蟹猴的围产期行为学验证结果显示,努责、摸舔产道、趴卧或躺卧、身体辗转和翻滚的行为指标均以不同的频次出现,其中努责和趴卧/躺卧的权重最高,权重值分别为35.5%和27.2%。可以依据这两个行为对食蟹猴的分娩发生做出精准判定。精准判定分娩发生并经兽医助产的食蟹猴平均活产率达到87.1%,明显高于无辅助自然分娩的平均活产率63.5%,二者具有显著差异(P<0.05)。结论精准的食蟹猴分娩判定结合兽医助产可显著提高实验用食蟹猴的活产率。
Objective Observing and analyzing the delivery behaviour of cynomolgus macaques,to establish the criteria for determining the occurrence of delivery in cynomolgus macaques,and then combining with veterinary assistance in order to improve the live birth rate of cynomolgus macaques.Methods By backtracking and analyzing the surveillance videos of 112 perinatal cynomolgus macaques with a gestation period of 140 d or more from 2017 to 2021,we observed and recorded the main behavioural manifestations of the cynomolgus macaques during labour,including Valsalva's maneuver,touching and licking the birth canal,lying on their backs or stomachs,and rolling and tumbling of the body.On this basis,we established the weights of delivery-related behavioural indicators and exhaustively analysed the perinatal behavioural performances of 30 cynomolgus macaques for delivery determination.Results The perinatal behavioural validation results of the 30 cynomolgus macaques showed that the behavioural indicators of Valsalva's maneuver,touching and licking the birth canal,lying on the stomach or on the floor,body rolling and tumbling occurred with different frequencies,among which Valsalva's maneuver and lying on the stomach or on the back were the most important,with weight values of 35.5%and 27.2%,respectively.These two behaviours can be used to accurately determine the onset of parturition in cynomolgus macaques.The average live birth rate of the monkeys that were accurately determined to have given birth and were assisted by veterinarians reached 87.1%,which was significantly higher than that of the monkeys that had unassisted spontaneous deliveries,which was 63.5%,and there was a significant difference between these two rates(P<0.05).Conclusion The combination of accurate birth determination and veterinary assisted delivery can significantly increase the live birth rate of experimental cynomolgus macaques.
