Effects Of Guanidine Derivative On Growth, Metabolism, Immunity And Meat Quality In Broiler Chickens

This thesis studied effects of guanidine derivative (coded : H04) as metabolism regulator on growth, endocrine,immunity and meat quality in broiler chickens. First test: 160 Arbor Acres (AA) broiler chickens of one-day-old were random divided into four groups. This test was from 1st day to 42nd day. The test studied the effects of the different dosage H04 on growth metabolism, endocrine, serum glucose, meat quality, calcium and phosphate in skeleton and serum , slaughtering performance in broilers of prophase and metphase. Experiment group compared with the control group,the results showed that:1. body weight gain were increased in groups of 15, 25mg H04 (p<0.01,p<0.01), feed intake were increased (p<0.01) and the feed/gain were decreased in groups of 15, 25mg H04 (p<0.01,p<0.01), a group of 25mg H04 has best.2. group of 25mg H04 can increase the level of triiodothyronine(T3)(p<0.05) , insulin(p<0.01), thyronine(T₄)(p<0.01), and decrease the level of glucagon (p<0.05)in serum, but group of 25 mg H04 can decrease the level of serum glucose.especially H04 can control glucose higher level in serum after taking feed and the level of fasting glucose of serum were not lower than control group.3. There were significant effects on the dressing percentage, semi-evicerated carcass weight rate, evicerated carcass weight rate of the group of 25mg H04. There were no significant effects percentage of quarter, percentage of leg muscle, percentage of breast muscle , on the concentration of the calcium and phosphate of skeleton; but all experment groups can extremely significantly increase the crude protein(p<0.01) ,crude fatty (p<0.01),on the concentration of the calcium(p<0.01) and phosphate(p<0.05) ,total protein (p<0.01)in serum; and decrease total cholesterol (p<0.01) in serum. Second test: In this test, 64 Arbor Acres(AA) broiler chickens of 30th day were random divided into four groups . This experiment period was from 30th day to 65th day. The test studied the effects of the different dosage H04 on growth metabolism, endocrine, serum glucose, meat quality.calcium and phosphate of skeleton and serum and slaughtering...
