Abstract
Gastrointestinal nematodes (GINs) remain a major
constraint associated with the profitable production of goats under grazing
conditions. The present study was planned to determine the comparative
susceptibility of Dera Din Panah (DDP) and Nachi breeds of goats towards
artificial infection with Haemonchus (H.)
contortus. To this end, a total of 24 goats of each breed were administered
with third stage infective larvae of H.
contortus through early and late infection protocols. The differences in
faecal egg count (FEC), post necropsy worm count, rate of establishment of
infection, packed cell volume (PCV), haemoglobin (Hb), eosinophils, total serum
protein (TSP) and serum albumin (SA) were compared to check breed susceptibility
to worms. Both breeds reflected significant (P<0.05) differences in
aforementioned parameters at different time intervals post infection. However,
Nachi breed showed a compromised response towards artificially infection with
H. contortus as compared to DDP breed.
Overall, higher FEC, higher number of adult worm recovery along with significant
reduction in PCV and Hb depicted that Nachi is comparatively more susceptible to
H. contortus infection as compared to
DDP. In conclusion, difference in response towards
H. contortus infection may formulate
the base of selective breeding of resistant goat breed (DDP) in the area.
