Carcass, Ceacal Microbial Population and Immune Parameters of Broilers Given Different Levels of Mixed Lemon Grass (Cymbopogon Citratus) and Garlic (Allium Sativum) Extract

The experiment was conducted to evaluate the carcass, caeca microbial parameters of broilers fed different levels of mixed lemon grass and garlic extract (CLGE). Five hundred broiler chickens (Ross 308) were allotted to five treatments with five replicate consisting of 20 birds each in a completely randomized design (CRD). The first group T1 was given 0.025g/litre Neomycin in water while T2, T3, T4 and T5 were given CLGE at levels 3.0ml/litre, 6.0ml/litre, 9.0ml/litre and 12.0 ml/ litre of water respectively. The experiment lasted for four weeks each for the starter and finisher respectively. Results on dressing percentages revealed that birds given 12.0 ml/l CLGE was highest (76.87%) followed by those in T4 (76.54 %), T3 (75.61 %), T2 (75.00%) and T1 (70.01%). Significant influences (P
