Studies were conducted to investigate the feeding effect of dietary complex mineral on the performance of poultry. Each study was classified as first experiment (laying hens) and second experiment (broilers).
In Experiment 1, five levels of complex mineral(0, 0.2, 0.4, 0.6, 0.8%) were added with commercial diets and fed to four hundred fifty Hy-line Brown from fifty four to sixty five weeks of age. Egg production (%), egg weight (g), daily egg-mass, and egg quality were calculated in every four weeks, Blood composition, and bone mineral density were measured at the end of experiment. Egg production (%) increased as the dietary addition of complex mineral increased up to the 0.6% complex mineral addition with basal diets. Feed intake also increased similar to that of egg production. However, there were no different feed efficiency among the treatments. Eggshell thickness and breaking strength were significantly higher in the birds fed complex mineral than control from sixty weeks old to the end of experiment(P<0.05). Albumin height and Haugh unit were also significantly higher in the birds fed complex mineral compared to those of control group. AST of birds fed complex mineral showed significantly higher than control. However, neutral fat content of blood tended to increase in complex mineral treatments. Bone mineral density also increased upto the 0.4% complex mineral addition. The results of this experiment indicated that the optimum complex mineral was 0.6% to stimulate the performance during the finishing period of laying hens.
In second experiment, Complex mineral was fed with 0, 0.05, 0.10, 0.15, 0.20% to commercial diets for four hundred one day old Cobb X Cobb broiler chicks. Weight gain (g), feed intake(g) and feed conversion were weekly calculated for five week. Blood composition, and meat quality were measured at the end of experiment. Weight gain increased up to the 0.1% dietary complex mineral addition to basal diets. Feed intake showed no consistency among the treatments. Feed conversion seemed to be improved in the birds fed complex mineral addition diets, but not statistically different of all treatments. Albumin, glucose and other blood parameter were improved related with health in chickens tended to improve at the level of 0.05% complex mineral addition treatments. Drip loss in breast meat was significantly decreased in more than 0.05% complex mineral addition. The optimum complex mineral to improve the broiler performance and other parameter related with health was 0.10% addition with commercial diets.
