Abstract
Microbiological and chemical characteristics of a zootechnical additive were determined for its use in animal feeding. The production process consisted of batch submerged fermentation at 18 ± 2 °C for seven days, mixed with an absorbent material, and then dried naturally. Two batches were formed, and the concentrations of mesophilic aerobes, fungi and yeasts, enterobacteria, total coliforms, Escherichia coli, Salmonella, and Listeria were calculated in duplicate. Humidity percentage, crude protein, ash, fat, crude fiber, total carbohydrates, pH, and total solids were also determined. The solid additive presented 1.4x107 cfu/g of mesophilic aerobes, 106 cfu/g of yeast, absence of pathogens, 14.2 % of humidity, 14 % of protein and crude fiber, 11.8 % of ash, 0.21 % of fat, pH of 6.72, and 3.0° Brix. Results indicate that the product has potential for its use as a zootechnical additive.
