Prevalence of mastitis and productive characterization in small producers of Simijaca and Tenjo (Cundinamarca), Colombia. rev. colombiana cienc. anim.

Bovine mastitis is an infectious disease of the mammary gland, generated by a bacterial invasion, resulting in a decrease in the quality and quantity of milk, as well as in the profitability for the producer. Subclinical mastitis is the most frequent and has a prevalence of 45.35% in small producers. The objective of this study is to determine the prevalence of bovine mastitis and characterize some productive parameters of small producers in the municipalities of Tenjo and Simijaca. A cross-sectional study was conducted where twenty small producers were surveyed, 14 from the municipality of Tenjo and 6 from Simijaca, where the productive parameters and dairy management were addressed, in addition, a CMT test was carried out to evaluate the prevalence of these municipalities. Finally, OpenEpi statistical software was incorporated, conducting descriptive statistics of the data, with which it was possible to identify that 46.32% of mastitis (clinical, subclinical, and lost quarters) in general, 50% in the municipality of Tenjo and 38.46% in Simijaca Cundinamarca. Also, a classification of the farms was made according to the average daily milk, classifying them into producers of <11L and ≥11L average per day, farms <11L presented 44.91% of mastitis and ≥11L 47.38%. of mastitis, showing that Tenjo cows and farms producing ≥11L average day are more susceptible to mastitis due to the management given to them.
