Determinación de los microorganismos presentes en el moco cervical de vacas lecheras post parto de las ganaderías de la hoya de Loja

Reproductive problems in dairy cows in the basin of Loja, can become a serious constraint on livestock production. This research was aimed at determining the presence of reproductive abnormalities and microorganisms capable of decreasing the activity of the reproductive tract in cows post calving. 85 samples were taken from cows ranging from one to 30 days postpartum from the various sectors that make up the basin of Loja, of different age, race, body condition, postpartum and parity. Samples of cervical mucus obtained by a swab through stuard making a scraping on the inside making the seizure of cervical mucus, for submission to the various stains such as Ziehl Neelsen, Gram, potassium hydroxide and iodine, to differentiate bacteria, fungi, protozoa in laboratory animal microbiology Biotechnology Center of the National University of Loja; complementarily an assessment of the color, odor, density of mucus and pH of the vagina was made. The results revealed that in all post calving cows, normal mucosa (pink) was observed; for odor, it was found that there were no abnormalities and in most cases, a transparent aqueous mucus was observed type regarded as normal. In vaginal pH reading we see that the 95.29% of cows, had a pH ≤ 7. As can say that stains only Gram stain was possible to find compatible with bacterial microorganisms such as diplococci, streptococci, tetrads, staphylococci, bacilli, estreptobacilos, fences (x, j, and v). The findings as to establish that in the cervical-vaginal mucosa post calving cows on farms the basin of Loja, live bacterial organisms that make up the normal flora of the early postpartum; and therefore are not infectious risk associated complications in any animal reproductive stage.
