The pathogen is acid-fast mycobacteria similar to Mycobacterium avium.
Let's learn about the treatment of bovine paratuberculosis.
Clinical diagnosis of bovine paratuberculosis
Refractory diarrhea and emaciation are typical clinical manifestations of bovine paratuberculosis, and cows with low feeding management level, poor environmental conditions and high yield are more common.
Because there are many diseases that cause intractable diarrhea, laboratory pathogenic examination is needed to diagnose paratuberculosis.
Pathogen examination can scrape small mucus and blood clots from rectal mucosa or feces for clinical cases.
The corpse can scrape the mucosa of ileum or ileocecal flap, make a smear and examine it with acid-fast staining microscope.
In addition, allergic reaction diagnosis, serological diagnosis, immune dot test and DNA technology were also carried out.
Second, the prevention and control points of bovine paratuberculosis
(1) Prevention and control principles Strengthen feeding management (especially in calf period), improve disease resistance, do a good job in environmental sanitation, disinfect regularly, strictly quarantine, and eliminate in time.
(2) When strictly quarantining imported livestock, it is necessary to conduct quarantine and confirm health before breeding.
On the basis of close observation and regular inspection, all cows are allergic 4 times a year (at intervals of 3 months), and negative cows are subject to quasi-adjustment or external adjustment.
When three consecutive quarantine tests are negative, it can be regarded as a healthy group.
(3) Eliminate the sick cows with obvious symptoms in time, and eliminate the cows with obvious symptoms after various tests.
However, cows in the third trimester of pregnancy can be killed under strict isolation conditions by feeding colostrum to their calves three days after delivery.
Those with positive allergic reaction and mild clinical symptoms will be isolated and eliminated in batches.
Three, the treatment of bovine paratuberculosis matters needing attention
There are too many diseases that cause intractable diarrhea in clinic, and all cases of intractable diarrhea must be thin, such as intestinal tuberculosis, salmonella, eperythrozoonosis, parasitic diseases, lead poisoning, malnutrition and so on.
Therefore, in the absence of laboratory examination, prescribe some intestinal anti-inflammatory drugs, antidiarrheal drugs, anthelmintics, and even traditional Chinese medicines for treating diarrhea due to spleen deficiency. Most of them are ineffective and some are effective, but once the drug is stopped, diarrhea is still treated correctly.
