Association of MHC-DRB1 Genotypes and Environmental Factors with Parasitic Load in Osmanabadi Goats | Chapter 5 | Research Perspective on Biological Science Vol. 7

 

Osmanabadi goat is reared in arid and semi-arid regions of India and plays a role in the economy of rural livelihood. Small ruminant practices in India face the major challenge of parasitic infestation. Gastrointestinal nematodes create a major threat to the production performance of small ruminants. Infection in the gastrointestinal tract with parasites is still one of the main constraints to goat production and poses a major global threat to animal production, which leads to serious economic and health problems. Hence, the present study was designed to evaluate the effects of different genetic and non-genetic factors on parasitic load of these goats in Udgir tehsil of Latur district of Maharashtra, India. The variation due to season, age, sex, farm and genotype of the TaqI locus of the MHC DRB1 gene on Faecal Egg Count (FEC) and Haemonchus Egg Count (HEC) in the flocks was studied. Descriptive statistical analysis was performed to analyse all the collected data. Analysis of Variance (ANOVA) was used to compare variables across different categories. The study comprised 84 animals, and the results indicated that the season and genotype had a significant effect on FEC and HEC in these flocks reared in an organised and non-organised farm. The highest FEC values (mean: 1119.047 ± 73.44) were recorded during the monsoon season, followed by the summer season (mean: 403.5714 ± 57.29) and the lowest values (mean: 116.66 ± 28.94) in the winter season. The HEC was also highest (367.469 ± 34.59) in the monsoon, and the winter season had the lowest values (mean: 116.66 ± 17.091). Among the genotypes, the BB genotype had the lowest FEC (mean: 240 ± 39.99), suggesting that the BB genotype might be resistant to parasitic load. Based on the findings in the present study, it is recommended that goat farmers adopt targeted control measures during the monsoon season to manage parasitic infections effectively.
