THE EFFECT OF FEEDING LEVEL ON THE GENETIC RESISTANCE OF LOCAL BREEDS INFECTED WITH HAEMONCHUS CONTORTUS
GENETIC
FEEDING
HAEMONCHUS
LOCAL BREEDS
Sixty sheep of three local breeds (Awassi, Hamdani, Karadi) of age, 6-8 months were divided to two groups, the first fed on low level of nutrition. Each group then divided into Two subgroups, the first was infected with 500 larvae / Kg Haemonchus contortus & the second was used as a control. Egg G. fecal sample, staple length, P. c. v. Hb; weight gain were recorded weekly for 13 week post infection. Results revealed that all sheep traits of low level nutrition were significantly (P<0.01) more affected than high level nutrition group. Awassi breed was more reistant to infection with H. contortus than Hamdani & Karadi breeds.
