New Kuhn Power Tillers
Kuhn North America Inc. introduces the newly-upgraded EL 43 and EL 53 power tiller lines with working widths ranging from 42" to 74" and 38" to 74" respectively. The EL 43 is designed for seedbed preparation, gardening, greenhouse operations, and ground and landscape maintenance, while the EL 53 is a heavy-duty machine designed to meet the demands of contractors, landscapers and farmers.
The EL 43 and EL 53 model lines can be used with tractors up to 40 and 50 PTO horsepower respectively, both benefiting from a 10 horsepower increase over previous models. Improvements to the EL 43 include a larger diameter rotor shaft with four longer-wearing, flange- mounted blades, and easier-to-adjust skid shoes. The EL 53 incorporates a down pressure setting on the rear hood, providing firmer soil for an improved seedbed. Both lines maintain a sliding hitch frame, rear set gearbox, and heavy steel plates for the top deck and hood, all helping to provide strength and durability for optimum performance and long service life.
Replica CorumExposing Nine Vaccine Myths
With so many cattle vaccines available - nearly 125 vaccines are on the market - there is a considerable amount of information, and misinformation, out there. To help clear up some misconceptions. Vie Cortese, D. V.M., Ph.D., DABVP, Pfizer Animal Health, busts nine common vaccine myths.
Myth No. 1 : If a vaccine is licensed by the USDA, it will work all the time in all cattle.
False. The fact that a vaccine is licensed and available doesn't mean it always works.
There are many reasons a vaccine might not work, including:
* It was used on the wrong age of animal.
* The wrong disease outcome was measured.
* It was used on the wrong species.
* The disease was overwhelming.
* Animals were already sick.
Myth No. 2: "Annual vaccination" means a year of immunity.
False. We don't really know the duration of immunity. The USDA may not require duration of immunity studies. If a product successfully demonstrates efficacy at 14 to 35 days after the last vaccination, they are automatically given annual revaccination labels. This does not necessarily mean the animal may be protected for 12 months.
Myth No. 3: The higher the antibody titer (level) after vaccination, the better the protection.
False. Titers may be poor indicators of level of protection. There are many different antibodies involved in protection and nonprotective antibodies can also be measured.
Myth No. 4: Vaccines are not effective in young calves because of blocking by maternal antibodies.
False. The role of maternal antibody interference is not clearly defined. Depending upon the disease, the type of vaccine, the preexisting antibody levels and the route of administration, some vaccines may be blocked by maternal antibodies, but others are not.
U-Boat ReplicaGenerally, viral vaccines are not inhibited by maternal antibodies. Two exceptions are Bovine Viral Diarrhea (BVD) and parvovirus. And as a general rule, bacterins may be blocked by maternal antibodies. A noteworthy exception is Lepto hardjo-bovis.
Many vaccines for calves are not inhibited by maternal antibodies, so ask your vaccine supplier to see efficacy studies done in ca
