| Abstract | ||
| This study was designed to examine the effect of different doses of propolis on growth performance, some carcass characteristics and lipid with an average live body weight of 27.57±0.095 kg were used in this experiment. Lambs were divided randomly into four equal groups (4 lambs for each group). First group was considered as control (0) (without propolis), second, third and fourth group were treated with different doses of propolis at 10, 20 and 30 ml daily respectively for 60 days. lambs were fed on concentrate diet with dry roughage during experiment period. lambs were weighed at weekly interval just prior to morning feeding and feed intake were recorded daily for 60 days. At the end of the experiment period, after 12 hours of feed deprivation, the lambs were weighed and slaughtered, then the carcass characteristics (carcass weight, empty body weight and dressing percentages) were recorded. The lean meat samples were taken from each carcass for lipid oxidation analysis. The results showed that lambs were treated with doses of propolis at 10, 20 and 30 ml recorded a higher final body weight were 39.00, 39.70 and 41.15 kg respectively as compared with control (37.40 kg). It was observed from results that lambs treated with dose of propolis and other groups. The results showed that lambs treated with doses of propolis at 10, 20 and 30 ml had a higher daily gain in weight (0.183, 0.190 and 0.212 kg) respectively compared to control (0.159 kg), with improvement of feed conversion ratio for lambs treated with some treatments above. It was observed that the improvement in hot and chilled carcasses weights and dressing percentages (based on slaughter weight or empty body weight) and retarded in lipid oxidation (less TBA value) for lambs treated with doses of propolis than control. It could be concluded that propolis extract is could be acted as growth promoter and antioxidant. | ||
