Abstract
The present study was conducted at a private farm in Sadat City, Menoufia governorate, Egypt, throughout the experimental period from July to September 2018 in order to investigate the effect of dietary graded levels of Proact* supplementation on the Molar ducks performance, carcass traits, serum blood biochemical parameters, some histomorphological measurements and economic efficiency. A total of 240 Molar ducks one - day old chicks, were distributed at random into 8 groups each in 3 replicates, 30 chicks each. Chicks of group 1 (control) was fed the starter and finisher diets that did not supplemented with Proact. Chicks in groups 2, 3, 4, 5, 6, 7 and 8 were fed the control diets plus graded levels of Proact as follow, 0.25, 0.50, 0.75, 1.00, 1.25, 1.50 and 1.75/ kg diet, respectively.
The results indicated that: 1- Groups fed the three levels (0.75, 1.00 and 0.50g / kg diet) have significantly the heaviest body weight, average daily weight gain and the best performance index compared to chicks in groups fed the highest additional level (1.75g / kg diet) and the control group. 2- Birds fed different levels of Proact significantly consumed more feed than the control group. Whereas, birds fed Proact level (1.75g/ kg diet) consumed significantly less feed than the other Proact groups and nearly equal to the control group at the same periods 0- 3, 4 – 10 and 0 – 10 weeks of age. 3- Feed conversion ratio, performance index and were significantly improved ( P ≤ 0.05) with the supplementation of Proact. 4- Addition of graded levels of Proact to Molar diets was significantly affecting all carcass traits except for pre-slaughter and dressing percentage and significantly increased both serum glucose and AST enzymes, but significantly reduced serum createnine, cholesterol, triglycerides and total lipids compared to the control group. 5- Morphological sections of Molar ducks small intestine are revealed that villi height, width and villi height : villi width are significantly increased with the Proact supplementation levels up to the level of 1.25g/ kg diet and tend to decreased after that, but still better than the control. 6- Through our inputs and outcomes for 10 weeks old Molar chick's ducks, relative economical efficiency was increased with the addition of Proact up to 0.75g/ kg diet (112%) and net revenue about 95.82 L.E compared to 75.22 L.E in the un supplemented group. 7- In general, the obtained results in the present investigation indicated that supplementation of 0.75g Proact/ kg diet can be used in diets of Molar ducks for 10 weeks to improve performance and efficiency of diet due to an increase in small intestinal absorption and activity. This, in turn, resulted in an increase in European efficiency index and economic efficiency.
