This work was carried out focused on meeting the objectives, which is to determine the
prevalence of bovine mastitis and identify the causative etiologic agent in the gathering
of the community of Pulisa in Canton Cayambe, by testing California Mastitis Test
(CMT) and Somatic Cell Count (SCC) and Colony Forming Units (UFS). We worked
with 84 producer members where it was screened in drum when delivering your product
to collection center, this allowed to determine the sample of 99 cows 396/4 evaluated or
analyzed with the CMT test.
The prevalence obtained in this study according to epidemiological measure was
22.22%, that is to say of the 99 cows sampled, 22 were positive to some degree
diagnostic CMT, the prevalence of all sampled quarter was 8.84%, ie 35/4 a total of 396
quarters were positive for mastitis in any degree of severity. The prevalence of
individual rooms: Left prevalence previous quarter was 10.10%, ie 10 affected; prior
right for the fourth prevalence was 11.11%, ie 11 affected; Left back room for a
prevalence of 7.07%, ie 7 affected and to the right rear quarter prevalence was 7.07% ie
7 infected quarters.
The result of the "LAB-VET" Veterinary Clinical Laboratory confirmed the presence of
the following etiologic agents are: Staphylococcus aureus was reported in 14 samples,
ie 50.00%, Streptococcus agalactiae is reported in 9 samples, ie 32, 14%, of
Streptococcus dysgalactiae reported in 2 samples, ie 7.14%, 2 cases Escherichia coli,
which accounts for 7.14% of Pseudomonas aeruginosa and one case was reported ie
3.57% was reported.
To determine risk factors, epidemiological survey was used to each producer; where the
following items were determined: type of milking did not have a suitable place for
milking, without safe drinking water for the milking process and not have individual for
grooming cows towels, do not use glass sealant and predio, They do not perform
topping, do not know CMT testing field, unaware of the disease, know the order of
milking infected cows.
Losses that this disease causes were analyzed in different aspects such as CCS by
content percentage when research was $ 16.45 per day. Losses due to milk delivered
was $ 196.36. Losses treatment costs (medication more professional services) may
7
reach the $ 94 per cow. And losses from chronic mastitis, when discarded to the cow,
where not only production is lost, but also to the animal, an example where a cow with
an average production of 15 liters per day can cost between 900 and $ 1,200 was made
to purchase; but only 250 to $ 300 for disposal. |
