Comparative Studies Of Aloe, Propolis And Aureomycin On Performance Of Boilers

Abstract: 279 21-day-old boilers were randomly divided into 3 groups , of group 1. group 2 and control group with 3 replicates for each group, each replicate has 93 boilerso Aloe was added in basal diet in group 1, Propolis was added in basal diet in group 2, Aureomycin was added in basal diet in. control group. Feed experiment had been for 40 days. The results as follow:(1) The results showed that Aloe increased ADG ( average daily gain) by 8.20% (P<0.05 ) and Propolis increased ADG ( average daily gain) by 6.46% (P<0.05) than control group . Aloe increased F/G (feed/gain) by 6.46% (P<0.05) and Propolis increased F/G (feed/gain) by 5.60% (P<0.05). Aloe increased the metabolic ratios of protein by 8.81% (P<0.05 and the metabolic ratio of fat by 8.30% (P<0.05). Propolis increased the metabolic ratios of the protein 6.41% (P<0.01) and the metabolic ratio of fat by 10.08% (P<0.01).(2) Propolis decreased glucose of serum by 14.88% (P<0.05)than Aloe group, and by 11.65% (P<0.05)than Antibiotics group . Aloe and Propolis severally decreased the urea nitrogen of serum by 47.36%(P<0.05) and 53.05% (PO.05) than control group (3) Aloe significantly increased the breast rate by 8.48% (P<0.05)than control group and by 6.75% (PO.05) than Propolis . Aloe and Propolis increased leg muscle 17.07%(P<0.01) and by 4.78% than control group (P<0.05). Aloe and Propolis severally decreased the belly fat by 3.57% (PO.01) and by 4.05% (PO'.Ol) than control group.(4) Aloe and Propolis significantly severally increased the protein content by8.75% and by 5.84% (PO.05), they severally decreased the fat content of chicken by10.94% (P<0.05) and by 11.00% (?<0.05) than control group. The content of plumbum in group 1 was significantly lower than group 2 and control group, it severally decreased by 44.44%(P<0.01) and by 50% (P<0.01),There was no significant difference in the content of Arsenic and Nitrite among groups. Aloe and Propolis significantly increased the content of C 18:2 by 70.44%(P<0.05)and by 56.49% (PO.05) than control group,...
