Abstract: Rabbits play an important role in solving meat production deficiency particularly in the developing countries, which are mostly localized in tropical and subtropical regions. So, rabbits suffer from many problems related to hot climate.
In feeding trials, the effect of the partial replacement of berseem hay (BH) by Atriplex halimus treated with Trichoderma reesei (RS) and Enzyme on performance of growing New Zealand White (NZW) rabbits, was studied Seventy growing NZW rabbits of 6 weeks aged, 588.98± 62.05 g weighted were randomly divided into seven dietary treatment groups of 10 rabbits each. Rabbits in the first group were fed a commercial pelleted diet contained 30% berseem hay as a control group, while in the other six groups rabbits fed diets contained 7.5 and 15% untreated and treated Atriplex halimus with Trichoderma reesei (RS) or Enzyme to substitute 25 and 50% of BH of the control ration.
The results showed that rabbits fed diets of control, T5 and T6 were significantly increased (P<0.05) in feed intake and daily gain than those fed the other experimental diets. Plasma total protein, albumin and globulin of NZW rabbits .fed control and T5 diets were significantly increased (P<0.05) than those fed the other experimental diets. On the other hand, plasma AST. ALT. ALP, urea, creatinine and total bilirubin were significantly increased (P<0.05) than those fed to the control and T5 diets. However, rabbits fed on T6 ration showed insignificant differences for albumin, globulin, AST and total bilirubin values. Rabbits fed control, T5 and T6 diets recorded significantly (P<0.05) higher carcass quality % than those fed other experimental diets.
It could be concluded from the present study that replacing 25% or 50% of berseem hay by biological treated Atriplex Halimus with fungus in the ration of NZW rabbits resulted in better performance without any adverse effect on physiological responses and carcass quality under hot conditions.
Key words: Berseem hay, biologically treated saltbush, atriplex halimus, performance physiological response, hot conditions
