This work was undertaken at the Animal Farm, Department of Animal Production, College of Agriculture, University of Duhok during the period from 14th June to 14th September 2009, where a total of twenty weaned (3-4 month old) male Meriz kids with an average live body weight of 13.48 ± 0.62 kg were divided randomly into 4 equal treatment groups and received 0, 750, 1000 and 1250 mg/kg diet of vitamin C for duration of 90 days.

Rectal temperature and respiration rate was recorded at weekly intervals.

Also, blood samples from the jugular vein was collected at the start, mid and at the end of the experimental period for determination of some haematological parameters (haemoglobin, packed cell volume and N/L ratio), some biochemical attributes (serum protein, globulin, albumin, urea, Creatinine) and the concentration of T3 and T4.

Results revealed that Kids received a supplementation of vitamin C possessed nonsignificant lower body temperature than control group.

Also, a significant (P<0.01) decline occurred in rectal temperature as the period of the experiment advances.

Haemoglobin, packed cell volume and N/L ratio averaged 9.87 ± 0.32 g/dl, 22.20 ± 0.53 % and 0.57 ± 0.05, respectively.

With the exception of N/L ratio, treatment had no significant effect on the studied traits.

The mean serum total protein, albumin, globulin, urea and creatinine was 5.77 ± 0.08 g/dl, 2.69 ± 0.06 g/dl, 3.08 ± 0.06 g/dl, 36.64 ±1.63 mg/dl and 1.05 ± 0.03 mg/dl, respectively.

No significant effect due to supplementation of vitamin C was observed on these traits.

Also, result indicates that supplementation of vitamin C to kids had a significant effect on T3 only.
