EFFECT OF GREEN TEA POWDER AS AN ALTERNATIVE OF ANTIBIOTIC ON GROWTH PERFORMANCE, MEAT QUALITY AND BLOOD LIPID PROFILE OF BROILER

Abstract

A study was conducted with green tea powder to evaluate the effect on broiler growth, meat quality and the development of internal organ. The broiler growth, meat quality and the blood profile have been improving day by day by using green tea powder with poultry feed. The experiment design should be well planned. Biosecurity of experimental design was maintained properly. Feed intake, feed conversion ratio is efficient in experiment birds. The live weight gain was significantly (P<0.05) higher in the group of Green Tea in the feed. The initial body weights of group T_o, T₁, T₂, T₃ and T₄ day of the experiment were 176.8 ±1, 184.2±1.3, 185.1±1, 190.2±084, 180.2±1.22 gm respectively and after 35^th day of experiment final body weight were 1972±3.22, 1992±2.77, 1940±3.17, 1778±3.52, 1918±2.81 gm respectively. The net body weight gains were 1795.2±2.22, 1807.8±1.47, 1754.9±2.17, 1727.8±2.68, 1737.8±1.52 gm respectively and economics of production were analyzed and found the net profit per broiler. Green tea powder has significantly impact on feed intake T_o, T₁, T₂, T₃ and T₄ respectively 3058± 4.23, 2971±4.01, 2995±5.57, 3208±4.3 and 3226±5.25 and increase body weight. Here the total cholesterol is lower in the group of broiler supplied green tea 0.5% and compare to other group of GT and antibiotic group. Triglyceride level showed significant (P<0.01) differences among different groups where highest level was found in T₁ and lowest in T₃ groups  due to green tea powder concentration of blood plasma of broiler chicken.
