Abstract

With the purpose of nutritionally characterize a mixture of Cassava (CV) (Manihot esculenta),
Poultry Manure (PM), Soy Flour (SF), Rice Flour (RF), Soy Oil (SO), Cultivation of lactobacilli (CL),
we performed a bromatological analysis to pellets from raw material, with the following levels
of incorporation in the mixture:, (CV) 15%, (PM) 30%, (SF) 15%, (RF) 30%, (SO) 5%, (CL) 5%.
The bromotological study was done in the Department of Animal Science (DZO) in the federal
university of Viçosa (UFV), Brazil. We performed testing on raw protein(RP), Dried Material (DM),
Ash Content(AC), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Ethereal extract
(EE), Organic Material (OM), Non- Fibrous Carbohydrates (CNF), for which we obtained the
following results: PC: 13,16%, MS: 93,61%, AC: 29,98%, FDN: 30,91%, FDNcp: 16,88%, FDA:
21,20%, FDAcp: 11,90%, EE: 12%, MO: 70,02%, CNF: 27,98%. We concluded that the pellets
from the mixture of sub-products show nutritional characteristics with high potential in the use of
alternatives for feeding cattle in times of scarcity using agricultural sub-products available in the
northern region of Costa Rica.
