“…play a vital role in determining response, but also those factors such as antibiotics and coccidiostats which influence the microfloral population in their own right (Bedford, 1996c;Rada & Marounek, 1996;Vukic Vranjes & Wenk, 1996). In some cases they work together and synergize (Allen et al 1996) while in others they do not (Miles et al 1996). Even micronutrients such as zinc and copper significantly alter the microfloral fermentation profiles (Yenigun et al 1996) and so can be expected to interact with feed enzymes.…”

Many feed ingredients in use in monogastric diets contain significant quantities of antinutritional factors (ANF) which limit both their feed value and their use. Almost all enzymes currently being used address such factors to varying degrees, allowing for more economic utilization of raw materials. However, animal response to xylanase, P-glucanase and even phytase utilization reported in the literature tends to vary. Factors such as enzyme source, ingredient variety and environment under which the ingredient was grown, stored and processed into animal feed, age of animal, interaction with other dietary ingredients, and health status are shown to affect significantly the response obtained. As a result, the mode of action of xylanases and /I-glucanases is still debated due to too much emphasis being placed on interpretation of individual trial results without regard to the interactive factors or the literature dataset as a whole. Better understanding of such factors will improve data interpretation. While results with phytase are not subject to such extreme variation, they are nevertheless inconsistent in the degree to which inorganic phosphorus can be replaced by this enzyme. Greater understanding of the ANF and factors which interact to govern the response to added exogenous enzymes will undoubtedly improve the economic return and confidence in their use. Improved knowledge of ANF structure will result in development of enzymes directed towards far more specific targets, which enhances the likelihood of success and should reduce the overall enzyme usage.

A 4x2 factorial experinrent of seven weeks duration was conducted on day old broiler chicks (n=240) to study the efficacy of commercial feed enzynte preparation added @ 50g/quintal i n four experimental diets containing either maize, sorghum, finger :nillet as sole cereal source or a contbination of maize, sorghum, finger millet and pearl ntillet i n equal proportions on performance, nutrient utilization, carcass traits and feed cost of production. The body weight gain and feed efficiency were significantly lower (PcO.01) i n finger ntillet based diet, which were intproved (PcO.01) upon enzyme addition. However, addition of enzyme i n diets based on other cereals did not improve the performance of broilers. The enzynte addition significantly (Pc0.05) inrproved the dry matter and gross energy ntetabolizability with higher nitrogen retention from diet containing finger ntillet. The carcass traits remained unaltered (P>0.05) by various dietary treatments. Feed cost of broiler production was higher (Pc0.05) i n finger millet based diet. It is concluded that diet containing finger millet, a poor quality grain, can be intproved by adding contntercial feed eirzyl'nte preparation.
