Being invited to collaborate with the UNET ofice in Pregonero Town, where The University promotes “agricultural technitians” , Roberth and I went to that location. It has improvised a classroom in the Mayoralty building in town where we can to teach the class. The room is full of excited students.
After a brief review of health plans and notifiable diseases in cattle we went to a nearby farm owned by the family of one of the students. To get there, they themselves have rented an truck, which students filled up the roof rack has been heating up the big hill from where we can see the mirror of water from the Pregonero Dam.
It's one of those small farms that I like to visit, in very simple pens we see how 16 different crossbreeding cows are milked.
At first look we note with surprise the excessive amount of ticks that have these animals and the poor body condition of calves.
- Tell me Mr. Eustoquio. how you treat the cattle against ticks?.
- Well, professor, this topic product does not help much, I do all like the deppendant in store told me. I take the same container's cap like the measure and mix it with of20 liters of water in my back pump and I spray the 16 cows and repeat this every week and look Dr. How no more ticks is posible to fix to the cattle. They are yet full of ticks.
I try to identify the product, but it's impossible. A small aluminum bottle without label is what Mr. Eostoquio hand extend to me. I look at the size of the cap and really do not think it get more than 5 ml.
- Hear me Mr. Eustoquio. It is not known product without label. But generally these products are dosed at 1 ml per liter of water and I don't think the cap give us the amount enought. On the other hand, dip 16 cows with20 liters of product, however well prepared, it is really insufficient. It is advisable to use 4 liters of prepared dilution per cow, you must apply it against the hair, its from the bottom to up and back to forward, ensuring good aplication. And I have to say you, if you've already been using for a long time these way, the ticks already accustomed to the product, as you have been exposed they to repeated small doses this is the perfect way for them to become resistant. In terms of frequency, here we see ticks Boophilus and against this is sufficient an effective bath every 21 days.
Upon rotation of products, we also say, do not overdo it. We recommend using a product, well prepared and well-implemented and continue to use as we will succeed. If there comes a time when there is no effective, well, we will change the active chemical. It is said that between 6 months and one year may be the length of time to deplete the effectiveness of the product.
- And another question Don Eustace: What have been applied to these calves?
The calves had dry hair, erect (hirsutism), swollen abdomen, very weak, pale mucous membranes and some diarrhea, none had fever.
At that moment appears on the scene the son of Mr. Eustoquio, and he said: - No teacher, I say you that my father has been injecting ivermectin but puts them double and triple doses and is injected intramusculary. As will be the thing that those calves went out of here "sniffing" to ivermectin.
- Well guys, let me say that it is dosed 1ml subcutaneous per50 kg of body weight. I've never seen used intramuscular and less at such high doses. Anyway we will take blood samples and stool for processing it right here.
I like people to accompany me as our Thecnitian Roberth, I go to the backyard of Don Eustoquio and we have allready our "Laboratory in place”: microscope, centrifuge, glass material. And Roberth is explaining to students the sample processing .
After doing the analysis, I observed amazed the high parasite count of nematodes eggs that had the calves. The cows also showed infestation by nematodes and Fasciola.
Well, relying on word of these producers, we think the application form and overdose of this ivermectin was not really effective. However, we recommend the use of a product based on benzimidazole.
The aim of these practices is that students learn the importance of laboratory diagnosis in conjunction with the exploration of the animals and know that the products have some indications that must be met before saying "this product is bad."
To vary a little thing, very early the next day we went to enjoy the facilities of the Camp "La Trampa " in the dam near the town. We are country people and we like outdoors living ...
