Supplementation of multi-enzyme and multi-species probiotic in poultry diets

What is it about?

A total of 180 Hy-Line W-98 hens, 40 weeks old, were assigned into four treatment groups so that there were 45 laying hens in each group. Four dietary treatments were randomly assigned to the four groups of hens. Hens in Group 1 were fed basal diet only (negative control), Group 2 was fed basal diet
antibioticat a level of 2.0 g/kg (positive control), Group 3 was fed basal diet
multi-enzyme at a level of 2.0 g/kg (ES) and Group 4 was fed basal diet
multi-species probioticat a level of 0.5 g/kg (PS). Addition of either enzyme or probiotic supplementation to the basal diet significantly increased the egg production, egg weight and egg mass of hens than the negative control group. Feed conversion improved with the addition of antibiotic, enzyme and probiotic than the negative control. Haugh unit score was significantly increased in the groups fed the ES and PS diets when compared with negative control group. High-density lipoprotein-cholesterol was significantly increased by probiotic supplementation compared with other dietary groups.The geometric means haemagglutination inhibition titres of birds fed on diets containing antibiotic, enzyme and probiotic supplementation were higher from 28 to 70 days than that of negative control.

Why is it important?

Numerous studies have been conducted to determine the effect of enzymes and probiotics on performance during the growing period in broilers. Therefore, the objectives of this study were to investigate the effects of supplementation of multienzyme and multi-species probiotic on the performance, egg quality parameters, haemato-biochemical parameters, humoral immunity of hens during the laying period.
