ABSTRACT
The study compared growth-promoting and anti-lipogenic characteristics of three phytogenic feed additives (PFA) in the diet of broilers. A total of 250 day-old Cobb broiler chicks were randomly assigned to five dietary treatments with five replicates of 10 birds each in a completely randomized design. Five experimental diets at starting and finishing phases were formulated. Diet 1 was the control with no PFA, diets 2, 3, 4, 5 contained PFA (garlic, turmeric, moringa) at 20gkg-1 diet and blend of the three (at 1:1:1) respectively. Feed intake and body weight gained were determined on weekly basis. There were significant (P<0.05) changes in body weight gain, feed intake, and feed conversion ratio. Bodyweight gained increased by 16.3 - 22% from Tumeric to moringa. Protein digestibility increased by 5% and 3% in birds fed garlic and the blend respectively while about 4% increase in fat digestibility was observed in birds with PFAs. The PFAs exhibited varied positive influence (P<0.05) on carcass yield, but no difference (P>0.05) was observed in the organ weights of the chickens. The fat deposition was substantially reduced (P<0.05) in birds with PFAs. The blood triglycerides, cholesterol, and low-density lipoprotein (LDL) were lower (P<0.05) in groups fed with PFAs. All the PFAs significantly increased the HDL above the value obtained in control. No mortality was recorded throughout the experimentation period. It was concluded that the three PFAs and their mixture used in this study improved the performance, nutrient utilization, and carcass traits of broilers. The overall benefits accrued in birds fed with the blend of the PFAs. While garlic showed a higher anti-lipogenic tendency, moringa had a greater influence on the feed intake and growth of the experimental birds.
