Abstract
sorbitol, N-acetyl-glucosamine, maltose, lactose, melibiose, sucrose, trehalose, inulin and D-raffinose. It was demonstrated that it produces enzymes that intervene in cellulose degradation, and other specific enzymes. This bacterium grew (15 LN CFU.mL-1) in the milk replacer and decreased the pH (6.08-5.82) and total reducing sugars (44-29 mg. L-1) in 10 hours. Finally, it was observed that calves that consumed the two doses of PROBIOLACTIL® (10 and 20 mL) showed differences (P <0.05) when improving weight gain (8 vs. 16 kg), and daily mean gain (163 vs. 326 g), as well as reducing the incidence of diarrhea. It is concluded that the bio-prepared PROBIOLACTIL® presents high metabolic activity and is capable
of causing a probiotic effect on productive and health indicators of lactating calves.
