Abstract:
| In order to know effects of dosing combination of selenium-vitamin E mixture in presence or absence of vitamin C to studying productive characteristics and body measurements of Awassi lambs. A fattening experiment was conducted on 24 heads of Awassi lambs in a private farm of local breeder in Al-Hamdaniya district, Nineveh governorate. In this study, Awassi lambs (males) were used was similar in age, ranging between 5 – 6 months, and were homogeneous in average of primary weight at the beginning of the experiment, as it ranged between 25.01 – 26.71 kg. The experiment lasted for three months. These lambs were distributed randomly into four groups, at a rate of 6 lambs for each of group. The first treatment included oral dosing of 5 ml of saline solution was prepared as control group. The second group included oral administration of 5 ml of selenium mixture, which was containing 2.5 mg of selenium and 250 mg of vitamin E. As for third group of Awassi lambs was dosed by 5 ml of vitamin C (500 mg of vitamin C). Finally fourth group was dosed of 5 ml of mixture of selenium-vitamin E with presence of vitamin C. The dosing process was carried out twice per week and continued until end of the fattening period. The results of the statistical analysis indicated an improvement in daily weight gains, total gains, and final weight were in favor for second groups (selenium-vitamin E mixture), third (vitamin C) and fourth (selenium-vitamin E + vitamin C mixture) when compared to the control group. As for body measurements of lambs, the results of this experiment showed a high significant increase (P≤0.01) in mean of body length, body height at frontward and backward of the animals, chest circumference and abdominal circumference in fourth group of lambs that were dosed (selenium-vitamin E + vitamin C) compared to control group. The dosing process continued at a rate of twice per week until the end of the fattening experiment. We conclude from this results of this experiment the emergence of a significant improvement (P≤0.05) in the production characteristics in favor of groups that were dosed with a mixture of (selenium – vitamin E) , vitamin C and combination of (selenium – vitamin E + vitamin C) compared to the control group. As a result of significant improvement in productive performance of the lambs and positive correlation between live weight and body measurements, which was resulted a highly significant change (P≤0.01) in different measurements of the lambs. |
