Item The effect of genotype, drying conditions and microbial enzyme supplementation of the nutritive value of hybrid and open pollinated maize grain for broiler feeding.(2001) Khumalo, Kwazi Cyril Elvis.; Slippers, S. C.Three experiments were conducted to examine the effects of tannin inclusion in the diet; heat treatment of maize; and maize genotype and sex of broilers; on the nutritive value of maize-soyabean based diets, as affected by dietary enzyme supplementation. In Experiment 1, six hundred day-old Ross male chicks were given 5 main diets. The 5 main diets were based on hybrid yellow maize and a commercial soyabean concentrate and supplemented with tannin at 0, 5, 15, 20 or 25 g/kg. In addition each diet was either supplemented with Avizyme 1502 (Finnfeeds International, UK) at 1 g/kg diet, or not. The birds were given experimental feed from day one to day 22 and the experiment was a completely randomised design with 5x2 factorial arrangement of treatments, and 6 replicates. The inclusion of tannin in the diet significantly reduced feed intake (P
