| Abstract |
A 3 x 3 factorial design experiment was conducted to study the effect of three manganese levels (30, 60 and 90 mg/kg diet) and three levels of vitamin D3 [500, 900 and 1300 international Chick Unit (ICU)/kg diet) on growth performance and carcass traits of growing Japanese quail during 1-6 weeks of age. A total number of 486 unsexed one-week-old Japanese quail chicks were randomly distributed into nine treatment groups 54 chicks each with 3 replicates (each of 18 chicks). Chicks of all experimental groups had nearly the same initial live body weight.
Results obtained could be summarized as follow:
Results of different manganese levels studied showed higher values of live body weight, weight gain and feed intake for chicks received 60 compared to those having 30 and 90 mg manganese /kg diet. However, the differences between chicks fed 60 and 90 mg manganese /kg diet in the previous growth performance traits were not significant. Dietary manganese level had no significant effect on feed conversion during all the experimental periods studied.
The different vitamin D3 levels had no significant influences on live body weight and weight gain values of quail during all experimental periods, while feed intake 1-vas almost significantly (P<0.05) increased with 500. and 900
vitamin D3 levels compared to 1300. 1CU/kg diet during 1-4 and 1-6 weeks of age. Feed conversion values were improved (P<0.05) with the higher vitamin D3 level (1300 1CU/kg diet) only during the starter period (1-4 weeks of age).
Results showed significant (P< 0.05 or P<0.01 ) interact ion effects due to level of manganese and vitamin D3 on body weight at 4 weeks of age, weight gain, feed conversion during 1-4 weeks of age and feed intake during all the experimental period.
Either manganese or vitamin D3 levels had no significant effect on percentages of carcass, giblets, liver, heart and dressing except that gizzard percentage which increased significantly (P<0.01) with increasing either manganese or vitamin D3 level in the diet, However, there are significant (P<0.05 or P<0.01) interaction between manganese and vitamin D3 levels on carcass, gizzard and dressing percentages.
It could be concluded that 60 mg manganese level in the diet was adequate for growing Japanese quail from 1 to 6 weeks of age, Vitamin D3 level of 900 is better than either 500 or 1300 ICU/kg feed when diets contained adequate levels
Of Ca and available P. Also,the level of 60 mg manganese with 900 ICU vitamin D3/kg diet would he suitable for growing Japanese quail From I till 6 weeks of' age, under Egyptian local condition.
