EFFECT OF DENSITY AND DIFFERENT LEVELS OF GREEN TEA ON PRODUCTIVE PERFORMANCE, AND SOME BLOOD BIOCHEMICAL PARAMETERS OF QUAIL

Abstract

This research was conducted at the farm of the Animal Production Department/ College of Agriculture and Forestry/University of Mosul. A total of 624 unsexed quail birds (1- 49 days) were randomly distributed in cages as follows: The 1st, 2nd, 3rd, and 4th groups were included 44 birds/m2 and they were fed a standard diet supplemented with 0, 0.5, 1 and 1.5% green tea respectively. The 5th, 6th, 7th, and 8th groups were included 52 birds/m2 and they were fed a standard diet supplemented with 0, 0.5, 1 and 1.5% green tea respectively. The 9th, 10th, 11th, and 12th groups were included 60 birds/m2 and they were fed a standard diet supplemented with 0, 0.5, 1 and 1.5% green tea respectively. The results show a significant increase in live body weight, weight gain, improvement in feed conversion, production index and factor and albumen concentration within density 44 bird/m2. The same results were occurred, in addition to the decrease in cholesterol and triglycerides concentration, when adding the 1.5% green tea, while the feed consumption, mortality%, glucose, protein, lipid profile parameters, GOT, and GPT were decreased significantly (p≤0.05) in the same density and in the same level of adding tea that mentioned before. In the interaction between density and adding green tea, green tea traits improved most of the characters within the same density as compared with treatments without adding green tea.
