Abstract

Mastitis is one of the main diseases that affects dairy cattle around the world for different reasons such as: management, nutrition, environment or pathogens. The purpose of this research work is to determine the prevalence and factors associated with subclinical mastitis in lactating cows in the Flor de Manabí community of the canton of El Carmen, province of Manabí, through the California Mastitis Test. 200 cows, in 20 farms, sampling 10 cows in each for three months, resulting in 800 quarters from medium and large farms in the community. During the investigation, they gave a total of 16 infected cows corresponding to 8% while 92% of the cases are negative, which were sampled for each quarter, determining the infected at the rate of traces, grade 1 (+), grade 2 (++), grade3 (+++) and negative. In addition, according to the epidemiological measurements carried out to measure the apparent prevalence, we have 8% that was confirmed by the CMT test, which was later calculated using the Winepi online program. The presence of mastitis is related to the following risk factors: the lack of good milking practices, including hygiene at the time of milking, and misinformation about the consequences of the disease, which means that all these factors make the disease continuously present. in the herds of the producers of the "Flor de Manabí" community.
