Abstract

Effect of changes in live body weight and feed conversion ratio as inﬂuenced by enzyme supplements on basic post-slaughter measurements of broiler chickens fed cereal-based diets

Highlights

The application o f NSP-degrading enzyme preparations in broiler diets, especially with high proportions o f cereals, has become common practice duringENZYME SUPPLEMENTS - CARCASS QUALITY OF CHICKENS the last decade
The utilization o f exogenous proteases or blends o f NSP-degrading and proteolytic enzymes is beneficial to improving the performance value o f diets based on such vegetable protein sources as seeds of legumes, soyabean meal and rape seed products (Brenes et al, 1993; Simbaya et al, 1996; Pack et al, 1997)
Based on experimental data collected from different growth trials performed in our laboratory, the objective o f this work was to examine the relationships o f carcass yield and abdominal fat percentages with changes in final live body weight and feed conversion o f broilers as caused by supplementary feed enzymes

Summary

Introduction

ENZYME SUPPLEMENTS - CARCASS QUALITY OF CHICKENS the last decade These preparations are used to diminish the antinutritive effects o f viscous, soluble non-starch polysaccharides in wheat, barley, rye or triticale and to increase dietary nutrient utilization, energy metabolizability and bird performance (Brufau et al, 2001). There is relatively less information about the effects o f different enzyme additives on carcass quality attributes and slaughter value o f broiler chickens. This inspired us to make an attempt to find out how and to what extent some post-slaughter measurements are linked w i t h basic performance characteristics in broilers fed enzyme-supplemented cereal diets. Based on experimental data collected from different growth trials performed in our laboratory, the objective o f this work was to examine the relationships o f carcass yield and abdominal fat percentages with changes in final live body weight and feed conversion o f broilers as caused by supplementary feed enzymes
