Abstract

Generally, the best cattle industry is below the desirable ration of one animal is to one person. As of now a ratio of 1:5 exists. Several factors limit the development of the best cattle industry. One of them is the feed efficiency of the animal. A proper feeding program must be followed in order to obtain the desired daily gain within one production cycle. There are different least cost formulation methods of which the study had taken into consideration the two most commonly used methods in the Philippines. The RULE OF THUMB and COMBINATION METHODS had been compared to the EXACT METHOD which is a new approach to ration formulation in the United States. The nutrient efficiency of all three methods had been evaluated to determine if it can provide the necessary nutrients for a 200 kilogram fattening steer with the desired average daily gain {ADG} of 0.7 kilograms. The occurence of nutrient deficiencies in the Role of Thumb and Combination methods were supplement by the addition of molasses to the total rations whereas the Exact method had only used rice bran d1 to satisfy all the nutrient deficiencies. Moreover, after evaluating the cost of production for the small, medium, and large scale of feedlot fattening operations using the three formulated rations, it was found that the combination method the least cost thus resulting to a higher gross income while providing the animal with the highest level of each required nutrient. The exact and Rule of Thumb methods follow respectively. Even if the assumed price changes used were the pessimistic rate of increase for each concentrate ingredient the same results had still been obtained although the gross income had been reduced.
