Abstract

The present study was designed to investigate the different degrees of genetic resistance and resilience in non-descript goats of semi-arid zone of Mathura to natural infections with gastrointestinal nematodes to introduce future breeding schemes. Animals were found to be naturally infected by Haemonchus spp. (85%) followed by Trichostrongylus spp. (7%), Oesophagostomum spp. (5%), Bunostomum spp. (2%) and Strongyloides spp. (1%). Faecal egg counts and blood samples were collected for the determination of indicator traits such as faecal egg count (FEC), packed cell volume (PCV) and haemoglobin (Hb). The mean EPG, PCV and Haemoglobin (Hb) were 1121.6±175, 34.71±2.2% and 8.3±0.5 g/dl, respectively. Based on EPG alone, goats were divided into 3 groups (<800, 900–2,000 and >2,000) and their EPG values were correlated with Hb and PCV. EPG showed a significant negative correlation with both Hb and PCV (P<0.01).
