Performance of Coloured Broilers fed with Organic Source of Zinc (Zn) and Manganese (Mn)
Abstract:
An experiment was conducted to evaluate the effect of feeding organic source of Zn and Mn on growth performance of coloured broilers. Three hundred and twenty coloured broilers were assigned to four dietary treatments with four replicates of twenty broilers each. The experimental birds were fed one of the following four diets. T1-Basal diet (Control) with 100% supplementation of Zn and Mn from inorganic source, T2- Basal diet with 100% supplementation of Zn and Mn from organic source, T3- Basal diet with 80% supplementation of Zn and Mn from organic source and T4 Basal diet with 70% supplementation of Zn and Mn from organic source. The inorganic supplementation was ZnSO4 and MnSO4. The experimental diets were fed to birds for 42 days of age. Data was collected for weekly cumulative body weight, weekly cumulative feed consumption and FCR. Among the organic source fed groups 100 per cent replacement of organic source of Zn and Mn (T2) showed higher body weight (1375 g) followed by T4 (1329 g), T3 (1326 g) and Control T1(1252 g).Among the organic source fed groups 100 per cent replacement of organic source of Zn and Mn (T2) showed better FCR (2.09) followed by T1(2.15), T3 (2.26) and T4 (2.30).Thus organic minerals can be included at much lower levels in the diet than the current recommendations for inorganic minerals, without any negative affect on broiler performance.
