Genetic and environmental influences on faecal worm egg counts following natural infection in Barbari goats

The overall least-squares means for log-transformed faecal egg count (LFEC) and geometric mean of FEC (GFEC, epg) of animals in the Barbari flock were 5.3 1±0.13 and 102.35 unit eggs/g, respectively, during the study period. The present study also showed that genetic (sire) and environmental factors (viz., year of sampling, sampling month and age of animals) had significant effect on faecal egg count of Barbari goats. The parasitic load of the animals was increased with the increment of age of the animals. The moderate heritability (0.32±0.11) estimates for faecal egg count in this breed suggests the existence of some scope for improving this trait.
