    诱导排卵 养猫者常常希望在不进行实际配种的情况下让猫结束发情期。这可以通过诱导猫排卵来实现。诱导排卵有几种方法。最符合生理规律的方法是使用做了输精管切除术的公猫,或者经过睾酮处理的已去势公猫。被选来用于此目的的公猫,在做输精管切除术或去势手术前,应该是性欲旺盛且配种能力强的。使用公猫来检测母猫是否发情的一个优点是,公猫比主人更能判断母猫何时处于发情状态。对于那些发情时不会明显表现出外在发情迹象的猫…

  • 2.16 发育异常

    在北美,兽医接诊的患者中约有5%患有各种先天性缺陷。据报道,猪的发病率最高,猫的发病率最低。在有发育缺陷的动物中,每20只就有1只存在多种异常情况。 肌肉骨骼系统异常 肌肉骨骼畸形是迄今为止猫和其他物种中最常见的发育问题。它们的发生通常是由于胚胎中原始管状结构未能正常闭合。 裂体畸形是一种致命的发育异常,其特征是腹部有裂缝,后肢缺失或发育不全。曾有两只患有这种缺陷的小猫,出现了通过腹部裂缝的严重内…

  • 3.1 雌性生殖生理学

    性发育 家养母猫青春期开始的平均月龄为8 – 10个月。然而,其开始时间因多种因素而异,最早可在4个月,最晚则可能在1年或更晚。 青春期的开始与生长速度密切相关,母猫体重达到5 – 6磅之前,青春期很少开始。喂养良好且生长迅速的猫比生长缓慢的猫更早成熟。生长速度受遗传、营养、并发疾病和社会压力等因素影响。 青春期的开始也可能受日照时长影响。年轻母猫可能身体已准备好进入发情期…
