Resumen
The objective of this investigation was to evaluate the effect of supplementing an injectable compound of Cu, Zn and Mn on bovine mastitis. The investigation was carried out in the dairy farms of San Quintín (Lat. 22.4070, Long. 80.0448) and Tres Caminos (Lat. 22.4019, Long. 80.0563) of “Desembarco de Granma”, Plant and Livestock Company, Yabu of Santa Clara during the dry period. The animals used were crossbreeds of Holstein and zebu, these animals were milked two times daily and fed with CT-115 and natural grasses. 5 mL of the injectable compound (50 mg Cu, 100 mg of Zn and 50 mg Mn) was administered parentally to the cows in production and the cows in the last trimester of gestation, with repetitions every two months until three applications were completed. In the animals treated the prevalence and indice of subclinical mastitis was reduced significantly (P< 0.05) from 67.9% to 40.3% y 1.48 to 0.81; 62% to 33.3% y 1.27 to 0.55, in San Quintín and in Tres Caminos respectively. The risk index was estimated and it demonstrated that in the group of cows which was given the mineral supplement was affected 0.34 times less with mastitis subclinical with each cow that was not supplemented. The incidence rate was evaluated and it was discovered that the group of animals exposed to the mineral supplement was 6.3%, meanwhile the animals not exposed to the mineral supplement was 18.5%. It can concluded that the supplementation of Cu, Zn and Mn via parenteral reduced the presentation of mastitis subclinical, demonstrating a protective effect to reduce
the relative risk for this pathology.
