| description |
The objective of this study was to estimate the incidence of clinical mastitis (CM) in dairy farms and identify individual factors associated with these new episodes. Nine semipastoral dairy farms applying mastitis control and prevention measures were included and visited twice with an interval of 15 days. A random sample of cows was selected in the first visit and monitored during the following 15 days for the identification of new cases of CM. The incidence was determined as the ratio between the number of new CM cases during the follow-up period and the number of healthy cows at the first visit. The risk factors evaluated at cow level were udder hygiene, distance to the floor of the anterior quarter teat, parity and days in milk; at quarter level was evaluated the leaking milk, teat skin condition, presence of ring and hyperkeratosis and subclinical mastitis using the California Mastitis Test (CMT). A generalized mixed linear model was adjusted to evaluate the association between the factors surveyed and a new CM case. A total of 990 cows were analyzed and 62 (6.7%, 95% CI 5.0- 8.3) new cases of CM were identified. The factors associated to a new case of clinical mastitis in the final model were days in milking, udder hygiene and CMT level. Cows with very dirty udders (level 4) and CMT result ≥2 in at least one quarter showed odds ratio (OR) values of 2.56 (1.19-5.5) and 3.29 (1.5-7.2), respectively. Cow attributes identified as associated may be risk indicators for specific mammary health management in the dairy herd. |

El objetivo de este trabajo fue estimar la incidencia de mastitis clínica (MC) en tambos e identificar factores individuales asociados a nuevos episodios. Nueve tambos del tipo semipastoril que aplicaban medidas de control y prevención de la mastitis, fueron incluidos y visitados dos veces con un intervalo de 15 días. Una muestra aleatoria de vacas fue seleccionada en la primera visita y monitoreada durante los 15 días posteriores para la identificación de los nuevos casos de MC. La incidencia fue determinada como el cociente entre el número de casos nuevos de MC durante el período de seguimiento y el número de vacas sanas en la primera visita. Los factores de riesgo evaluados a nivel de vaca fueron: suciedad de la ubre, distancia al piso de la punta del pezón anterior, número ordinal de partos y días en lactancia. A nivel de cuarto se evaluó la presencia de pérdida espontánea de leche, condición del pezón considerando estado de la piel, presencia de anillo e hiperqueratosis. El grado de mastitis subclínica se valoró utilizando el California Mastitis Test (CMT). Un modelo lineal generalizado mixto fue ajustado para evaluar la asociación entre los factores relevados y la presentación de un caso nuevo de MC. Un total de 990 vacas fueron analizadas identificándose 62 (6,7%, intervalo de confianza-IC 95% 5,0-8,3) casos nuevos de MC. Los factores asociados a la presentación de un caso nuevo de mastitis clínica en el modelo final fueron días en lactancia, suciedad de la ubre y grado de CMT. Vacas con ubres muy sucias (grado 4) y resultado de CMT ≥2 en al menos un cuarto, mostraron valores de odds ratio (OR) de 2,56 (1,19-5,50) y 3,29 (1,5-7,2), respectivamente. Los atributos de la vaca identificados como asociados pueden ser indicadores de riesgo para el manejo especifico de la salud mamaria en el tambo.
