SWEET POTATO PROTEINIC BY PRODUCT
Feeding constitutes an essential factor to maximize animal production and represents approximately 50% to 70% of the total production cost.
To reach high productivity, production of animal feed for different species must be carried through by a balanced approach, supplying the nutritional requirements of each category, aiming at excellent performance along with a compatible cost for the market reality.
For each animal species it is necessary to obtain information such as: if the animal is destined for breeding, the amount of animals, productivity, annual replacement and the consumption of feed in each phase of production. This information will define the volume of feed to be produced and the raw materials used in the production of the feed.
Balanced feed offer the producer the tranquility to know that he is receiving a product that possess a manufacturing standard processes and quality control.
Mineral supplements are also indispensable in animal feeding. Its cost is defined in function of the used raw material, commercial mark, species that it is destined, vitamin inclusion, growth promoters etc.
The search for alternatives in the production of animal feed must occur frequently, being that the by-product generated by the sweet potato ethanol industry can be a great contributor for the production of feed, mainly with regards to the source of protein, that is, the sweet potato mass generated after the process of ethanol production.
Analyses demonstrate that the product can be used without restrictions, presenting high protein values and a considerable production of this by-product in the sweet potato ethanol plant. The production is approximately 150 kg (330.7 lbs) of product for each ton of processed sweet potato.
Table 1, demonstrate the chemical property analyzes of the sweet potato by-product after the ethanol production process.
