Dynamics of faecal egg count (FEC) in Haemonchus spp. infected goats of two Indian goat breeds, Jamunapari and Sirohi, in natural conditions was studied and effects of genetic and non-genetic factors were determined.
A total of 1399 faecal samples of goats of Jamunapari and Sirohi breeds, maintained at CIRG, Makhdoom, Mathura, India and naturally infected with Haemonchus spp., were processed and FEC was performed. Raw data generated on FEC were transformed by loge (FEC+100) and transformed data (least squares mean of FEC [LFEC]) were analyzed using a mixed model least squares analysis for fitting constant. Fixed effects such as breed, physiological status, season and year of sampling and breed × physiological states interaction were used.
The incidence of Haemomchus spp. infection in Jamunapari and Sirohi does was 63.01 and 47.06%, respectively. The mean LFEC of both Jamunapari and Sirohi (does) at different physiological stages, namely dry, early pregnant, late pregnant early lactating and late lactating stages were compared. Breed, season and year of sampling had a significant effect on FEC in Haemomchus spp. infection. Effect of breed × physiological interaction was also significant. The late pregnant does of both breeds had higher FEC when compared to does in other stages.
Breed difference in FEC was more pronounced at the time of post kidding (early lactation) when sharp change in FEC was observed.
研究了自然条件下感染血矛线虫属的两个印度山羊品种（Jamunapari和Sirohi）粪便虫卵计数（FEC）的动态变化，并确定了遗传和非遗传因素的影响。
对印度马图拉马赫杜姆中央山羊研究所饲养的、自然感染血矛线虫属的Jamunapari和Sirohi品种山羊的1399份粪便样本进行处理并进行FEC检测。对FEC产生的原始数据采用loge（FEC+100）进行转换，并使用混合模型最小二乘法分析对转换后的数据（FEC的最小二乘均值[LFEC]）进行拟合常数分析。使用了品种、生理状态、采样季节和年份以及品种×生理状态交互作用等固定效应。
Jamunapari和Sirohi母羊血矛线虫属感染率分别为63.01%和47.06%。比较了Jamunapari和Sirohi（母羊）在不同生理阶段，即干奶期、怀孕早期、怀孕后期、泌乳早期和泌乳后期的平均LFEC。品种、采样季节和年份对血矛线虫属感染的FEC有显著影响。品种×生理交互作用的影响也显著。与其他阶段的母羊相比，两个品种怀孕后期的母羊FEC更高。
在产羔后（泌乳早期）FEC急剧变化时，品种间FEC差异更为明显。
