New animal feeding systems based on the intensive use of tropical by-products
The development of efficient feedings systems based on tropical agro-industrial products and crop wastes can play an important role in the improvement ofa animal production practices, resulting in an increase in high quality protein production for human nutrition. Research within the context of developing feeding systems is based on the establishment of bio-mathematical relationships between inputs and outputs. This procedure will also result in rapid accumulation of knowledge on the feed value of feedstuffs and in the reduction of time and cost in a research program. As illustrated by research on the utilization of sugar cane by-products (molasses and bagasse) and crop residues (cane tops), input-input and input-output functions will serve to choose specific levels of each input to obtain bio-economic optimization and the synthesis of a feeding system. Sugar cane-derived feedstuffs are very low in protein, and their extensive use requires the addition of high levels of urea, which reduces the total weight output. However, net returns on feed lot operations can be as high as 25 percent. Moreover, the inclusion of starch, so as to provide 25 percent of the total ME, will cause a 30 percent improvement of weight gain. Feeding systems based on the efficient use of cull bananas and sweet potato crop residues are also being development producing net returns of 54 to 63 percent on the total investment, under present conditions in Costa Rica
