| Abstract |
Twelve Suffolk Ossinri, crossbred ewes were used in this study.
They were divided into three groups received three different rations:
Control ration (control group), 40 % ammoniated com stover contouring ration (ACS group) and 10 % broiler litter containing ration (BL group) .
Experimental period included 2 months preconception and 5 months pregnancy. Plasma levels of total protein, albumin, albumin/globulin ratio , urea, GOT and GPT were not influenced by dietary treatments but influenced by months of treatment. Plasma level of globulin increased while alkaline phosphatase level decreased in response to broiler litter treatment. Mean length of estrous cycle was longer in ACS group than control group (16.67 versus 15.44 days), while mean gestation length was longer in BL group than control group (152.25 versus 148 days). litter weight at birth was not influenced by treatment and not correlated with the length of gestation. Conception rate was not influenced by treatment, while lambing rate decreased in both ACS and BL groups. Mean concentration of plasma progesterone increased in response to dietary treatments in cycling ewes but not in pregnant ewes. Twin pregnancies were higher in progesterone level than single pregnancies (11.76 versus 8.39 ng/ml). lambs Growth during the first five weeks of suckling period decreased in the BL group . Digestion coefficients for crude protein ere 54.74 ,58.33 and 54.72, for TDN were 57.79 , 60.88 and 55.75, and for DCP were 7.7 , 8.85 and 8.08 for the control, ACS and BL groups, respectively.
