Efecto de un biopreparado probiótico sobre el comportamiento productivo y la salud deternero

The object wasstudy the effect of a biopreparation as probiotic additive in calves was conducted this research.20 animals of Siboney breeding after birth with similar alive weight (32 kg ± 0.23) and size (65 ± 0.8 cm) were selected. Afterward, tow experimental groups (control and experimental) were performed with 10 calves per group. Booth group receive same management and feed, but the experimental group received 20 mL of the biopreparation per calf directly to the mouth twice per week during the first two weeks and afterwards once per week till 90 days of experimentation. The results show to the experimental group with 8.25 kg of weight gain more than (p <0.05) control group. Similarly, the experimental group was taller (2 cm) than control group. In addition, the 70 % of animals in control group presented gastrointestinal diseases, while the experimental group had an increase of 10% of lymphocytes in blood. It was concluded that the biopreparation improved the bio-productive indexes of these animals, as well as increase the economic benefit
