Effect of different planes of nutrition on performance and meat quality of najdi lambs experimentally infected with haemonchus contortus [electronic resource].

Includes references.

In the present study, twelve Najdi lambs, experimentally infected with 104 third stage larvae of Haemonchus contortus, were divided into 3 groups, 4/ each. and fed on 3 different rations. The first group supplied just adequate energy and protein requirements, the second group fed on ration having 50%more protein, while the ration of the third group was higher in its protein and energy than the first one by 55% and 11% respectively. Infected lambs given high protein and energy diet demonstrated high final body weights, carcass weight and dressing%, with higher meat and fat Yild in addition digestibility of dry matterv crude protein and crude fibers were recorded in both supplemented groups. The chemical analysis and sensory evaluation of the lean meat revealed no statistical differences between the three groups. Conclusively, the plane of nutrition showed an upper hand over the parasitism. Key words: Meat quality, Najdi lambs, Haemonchus contortus.
