| Popis: | The response of broiler chicks to diets [basal diet (BD) containing toasted guar meal (TGM)-at 150 g/kg diet] supplemented with two levels of β-mannanase (β-M) enzyme at 36g (T-1) and 72g (T-2) and α-galactosidase (α-G) enzyme at 22g (T-3) and 44g (T-4) alone per 100kg diet were added. T-5 consisted of a combination of 36g β-M and 22g α-G per 100 kg diet. T-6 consisted of a combination of 72g β-M and 44g α-G per 100 kg diet was studied. All the diets were iso-caloric and iso-nitrogenous and fed ad-lib to corresponding treatment groups from day old to 42 days of age. The estimated residual galactomannan gum content was 4.98g/100g. Body weight gain and performance index score of broilers decreased (P 0.05) remains unaffected. However, enzyme supplementation to TGM diets had improved (P |
