This study aims to determine the prevalence of bovine mastitis in the community of
Canton Cayambe Muyurco by California Mastitis Test. For sampling was divided into
two phases one in milking morning and in the afternoon a total of 68 cows that give us a
total of 272/4 from small farms were sampled
During the investigation they gave a total of 26 infected cows corresponding to 38.24%,
while 61.76% of cases are negative with a total of 42 cows, which are sampling every
quarter infected at a rate determining trace 23.52%, 17.65% grade one, grade two,
14.71%, grade three, 20.59% and negative in 23, 52%.
According to epidemiological measures undertaken to measure the apparent prevalence
(Pa), we have a 38.23%, which was confirmed by the CMT test, which indicated a
specificity and sensitivity for detecting infection by 100%
Of the samples sent to the laboratory LAV BET in the city of Quito, for culture and
sensitivity Staphylococcus aureus and Streptococcus dysgalactiae reported 11.54%,
Streptococcus agalactiae and Escherichia coli 1.47%, Staphylococcus aureus and
Streptococcus agalactiae 2.94, Streptococcus 2.94 dysgalactiae and Streptococcus
agalactiae, Streptococcus agalactiae, Staphylococcus aureus and Escherichia coli 2.94%,
26.92% Staphylococcus aureus, Streptococcus agalactiae 30.77%, Streptococcus
dysgalactiae and Escherichia coli 1.47%
Of the etiological agents found in research 52% are resistant to streptomycin, 28% are
resistant to amoxicillin, and 20% resistant to ciprofloxacin.
The presence of mastitis have been associated with the following risk factors: lack of
good milking practices (hygiene at milking time), lack of prejudice that brings this
disease, no field testing CMT, misuse of antibiotics, and not perform tests to identify the
etiologic agent. All these factors make the disease is frequently found in herds of
producers.
The economic losses caused by the infection in downtown Gathering Muyurco
community that collects 700 liters per collection is estimated to lose 49, 17 liters of milk
per day and per month totaling 1475.10 liters with an economic representation of $
634.29 per month that producers are losing. |
