INFLUÊNCIA DA CIANOCOBALAMINA ASSOCIADA AO BUTAFOSFAN NA TAXA DE CONCEPÇÃO EM FÊMEAS ZEBUÍNAS SUBMETIDAS AO PROTOCOLO DE IATF

Abstract

The influence of cyanocobalamin associated with butafosfan on the conception rate of animals submitted to the IATF protocol in the municipality of Canarana, Mato Grosso, was evaluated. A total of 155 multiparous Nelore cows, raised in a semi-extensive regime on Brachiaria decumbens pasture and with a good body mass index score of 3, were evaluated. The application of catofos was done randomly in the batch of cows, and they could be divided into two groups: In the test group, the vitamin was applied to 83 cows, while in the control group, 72 animals did not receive the application, forming the control group. The IATF protocol was used with three managements, and the batch presented 61.29% pregnancy considering the two groups. The test group had 54 (65.06%) pregnant animals, while the control group had 41 (56.94%) pregnant cows. Therefore, the group that received catofós had 8.12% more conceptions compared to the control group, demonstrating that the vitamin played an efficient role in the replacement of macro and microminerals and improvement in reproductive influence.
