| The experiment was perfomed using a tota1 of 96 AVIA broi1ers (8 ) aged21 days. The broi1ers were random1y divided into 4 groups: contro1 gToup, whichwas feed on basic diet, Cysteanine (CS) group, which was feed on basic diet p1usCS 100mg/Kg BW. Dadzein (Da) group, which was feed on basic diet p1us Da 3mg/Kgdiet and speIgic group, which was feed on CS 50Ing/Kg BW+Da 1. 5mg/Kg diet. Therewere 4 rep1icates in each group. CS was added every 7 days, the anount of whichwas based on the broi1er's weight and tf he amount of the additi ves, and was givenonce. Da was added proportional1y into t}he diet and feed everyday. The experimentwas caTried on for 5 consecutive weeks, during this time the Iaboratory broi1erswas shined witll weak 1ight for 24 hours, and the temperature was kept at 22--24C, the feed and water was given rmdomly Many indexes were measUred, including thedisposition of body adipose, growth index, enzyIne, hormone and metabo1ism productsWhich were c1ose1y re1ated to adipose metabo1ism in b1ood and 1iver.Resu1tt The abdomina1 adipose contents of each group were l. 25I0. 09. 1. li 0. 32 x 1. 29 f 0. 27 and 1. 26 f 0. 11 percent respective1y: the subcutaneousadipose thickness were 0. 75i0. 20. 0. 70i0. 23. 0. 73f0. 2l and 0. 7l f0. l8 cmrespective1y. CS and Da disp1ayed their effects at different time of theexperiment, that is, the optima1 time for the effects of CS and Da were 39 daysold and 49 days o1d respective1y, as concerned with reduction of abdomina1 adipose,decreasing by 46. 46% and 37. 5on respective1y compared with the control group,and the difference was significant (p<0. 05). As concerned with the reduction ofthe subcutaneous adipose thickness, the best time for the effect of CS, Da andthe combination of them were 42 days o1d, 42 days o1d and 49 days old respectively,with the reduction rate of 22. 47%, 15. 73% and 16. 33% respective1y (p>0. 05),compared with the contro1 group. As concerned with the effects on the reductionof body adipose deposition, CS was the best candidate, with the Da the second,and the combination of both the last.the eating amount g/day. broiler of each group were l49. 47i40. 38. 32. 65I31. 71. 152. 22f45. 46 and l36. 59f26. 87 respectively: The 1iveweight gain ofeach group were 65. 53f7. 48. 71. 5lf 11. 86. 69. llf8. 59 and 65. 40f8. 81 g/day.broi1er respectively: the feed conversion rate of each gToup were 2. 29l0. 6l.1. 86i0. 34. 2. 22f0. 74 and 2. 07i0. 37 g feed/g 1iveweight gain respective1y.The eating anount in CS group was 1owest in the 7" week, l8. 54% lower than thecontro1 group. In CS + Da group, the 1owest eating aJnount took p1ace in the 8'..week, 2l. 7l% lower than the contro1 gToup. Da a1most did not affect the aJnountof food intake. The 1iveweight gain in the three group increased significant1yin the 7'.' week, with 37. 19%, 30. 78% and 1S. 25% higher than the contro1 grouprespective1y. The conversion rate of the foodstuff was a1so 1owest for the threegroups in the 7',' week, with 40. 44%(p<0. 05), 24. 26%(p<0. 05) and 27. 20% 1ower thanthe contro1 group respectively. The effect of CS on imDroving grOwth traits wasthe best, with the Da the second, and the CS+Da the 1ast.the Insu1in 1eve1 of each group were 3. 94l0. 20. 4. 36l 1. l7. 4. 3 0I1. 28and 4. 10t0. 50 u IU/mL respective1y: the G1ucagon 1eve1 of each group were3l9. 90 i 32. 72' 428. 40 l 50. l0' 473. 13 i 77. 0S and 354. 66 f 56. 88 pg/m1respectively.
