This is an excellent presentation on the use of enzymes in monogastric animal. Use of enzymes to obtain optimum performance of monogastric through maximum utilization of available nutrients in feedstuffs cannot be overemphasized. With the present situation of continuous increase in the price of feed, use of alternative feed ingredients hitherto not utilize as feedstuffs must be considered. Use of cocktail enzymes (on such alternative feedstuffs) that will enable the monogastric animal optimally utilize the available nutrients should be considered. This will reduced the cost of feed, increase return on investment for farmers and reduce environmental pollution that the alternative feedstuffs will have produced if not used for feeding animals.
