Abstract

This work examined the impact of enzyme preparation with specific activity towards non starch polysaccharides on performance, morphological characteristics of gastrointestinal tract organs, microscopic evaluation of jejunal mucosa, and microbial status of ileum, caeca, and excreta in broilers fed a diet containing a high content of lupine meal. One-day-old chickens (Ross 308, mixed sex) were randomly divided into control and experimental groups. Each group consisted of 36 birds, with 6 replications,and with 6 chickens per replication. The control group was fed the basal diet (consisting of maize and 40% of lupine), while the experimental treatment group was fed the basal diet supplemented with 0.06% commercial enzyme (Ronozyme VP). Chickens were fed diets in mash form for 4 weeks. Enzyme preparation significantly (P< 0.05) improved feed consumption and chicken growth, and slightly improved total tract digestibility of dietary ingredients and energy. Enzyme preparation significantly reduced (P< 0.05) the size of gastrointestinal tract organs and had an impact on jejunal mucous membrane of chickens evidenced by elongation of villi and deepening of crypts. No significant effects of dietary enzyme on counts of the analysed bacteria in the jejunal digesta were observed, but enzyme preparation significantly (P< 0.05) reduced the number ofEnterobacteriaceaein caeca and excreta, andcoliformsin excreta only (P< 0.01). Appropriate combination of enzyme preparations with activity towards degrading carbohydrates may offer a potential to reduce the deleterious impact of lupine in broilers.

Highlights

Soybean meal (SBM) is the most common protein supplement widely used in poultry feed, but in many countries including a majority of EU, SBM is an imported commodity

Summary

Introduction

Soybean meal (SBM) is the most common protein supplement widely used in poultry feed, but in many countries including a majority of EU, SBM is an imported commodity. Given the fact that Lupinus luteus appears to have the most desirable qualities as a potential primary protein source for broiler chicken diets (Petterson 2000), there is insufficiency of data on the effects of enzyme preparations on NSP in diets based on Lupinus luteus. Our preliminary studies showed that supplementation of LM based diets for young broilers with commercial multienzyme preparation (Energex) has the potential to reduce the anti-nutritional effects of NSPs in Lupinus luteus seed. The aim of the present study was to test the effects of the generation of Energex enzyme preparation brand Ronozyme VP added to diets containing seeds of Lupinus luteus as the primary source of protein on nutritional efficiency and gastrointestinal indicators in broilers
