Beef and dairy producers now have the flexibility to vaccinate pregnant cows and calves nursing pregnant cows against bovine reproductive and respiratory diseases with Vista, a modified-live viral (MLV) vaccine line, from Merck Animal Health, DeSoto, Kan. Reproductive diseases account for economic losses of $1 billion annually, and bovine respiratory disease (BRD) is the most prevalent disease in calves older than 30 days. The U.S. Department of Agriculture approval for Vista's vaccine line includes the following label additions: The cows or heifers being vaccinated should be vaccinated prior to breeding, within the previous 12 months, with any of the vaccines in this product line; fetal health risks associated with vaccination of a pregnant animal with MLV vaccines cannot be unequivocally determined by clinical trials conducted for licensure; and management strategies based on vaccination of pregnant animals with MLV vaccines should always be discussed with a veterinarian. Vista vaccines were first approved for use in 2005. For more information, contact a representative or visit www.merck-animal-health.com.
As fall gives way to winter, now is the time to think about a de-icer for a dock or body of water. In freezing temperatures, a de-icer keeps areas open for ducks, geese, and other water fowl as well as keeping an open area preventing winter fish kills. In 1967, Air-O-Lator Corporation, Kansas City, Mo., developed the Ice-Away de-icer designed to prevent ice formation in marinas and around docks. The Ice-Away lifts 500 gallons of water per minute upward to the surface, simultaneously drawing the warmer water from below. The stainless steel Franklin Electric submersible motor is water cooled and lubricated making it eco-friendly. There are no seals and bearings.

Company introduces hog feeder product to management line
Osborne Industries, Inc., has introduced a stainless steel rectangular hog feeder to its line of swine management equipment.
Double-sided wean-to-finish rectangular feeder models are available for dry and wet/dry feeding. The feeders are constructed with heavy duty, 304 welded stainless steel for long-lasting performance for years of operation in hog finishing facilities. The rolled edges provide structural strength as well as safety from sharp edges. The simple adjustment system promotes optimum feed efficiency and deep head entry into the feed trough helps achieve Osborne’s signature “no waste” pig feeding. Solid divider panels with pre-drilled holes allow for splitting the feeder among sort and grower pens, while the pre-drilled holes and knockouts allow for mounting the feeders in multiple applications.
Also made in Osborne, Kan., The Big Wheel Hog Feeders, Osborne’s other line of pig feeders, increases feed conversion rates and reduces feed waste with their mechanical flow design. The feeders allow fresh feed to always be available. The feeders have a variety of options, and are available in nursery, wean-to-finish, finishing, outdoor and ad-lib sow models.

Protecting dairy cattle immune function critical during transition period
Nutritional and management practices can have an impact on a dairy cow’s immune system during the transition period and minimizing stress in close-up and fresh cows is important in supporting their health, milk production and reproductive efficiency, according to Robert Corbett, D.V.M., of Dairy Health Consultation in Spring City, Utah.
Dr. Corbett noted that dairy cows experience a suppressed immune system at parturition, caused by the release of the stress hormone, cortisol, which makes them more susceptible to mastitis and a host of other health disorders. Elevated blood cortisol, he explained, causes white blood cells, known as neutrophils, to lose their ability to fight infections.
To minimize the drop in blood calcium levels at parturition, he recommended feeding transition cows a negative dietary cation-anion difference (DCAD) diet with the goal of reducing potassium (K+) and sodium (Na+) levels and increasing chloride (Cl-) and sulfur (S-) levels. Noting that clinical and subclinical hypocalcemia are major underlying causes of problems in transition and early lactating cows, he said that a high percentage of metabolic disease problems, as well as impaired immune function, are directly correlated to low calcium levels.
OmniGen-AF from Prince Agri Products, Quincy, Ill., is a nutritional supplement that can help support a dairy cow’s immune system, which, if working properly, provides defenses against multiple sources of year-round stress to help maintain overall cow health and productivity.
Animate, from Prince, is an anionic mineral supplement designed to help reduce the risk of low blood calcium in postpartum dairy cows and, because it is highly palatable, can help attain a negative DCAD diet while also maintaining high dry matter intake.

Tire lines added for large machines
The range extension of Super Flexion Tires (SFT), from Mitas, was presented at the Agritechnica fair in Germany.
Mitas SFT are made for high horsepower tractors with more than 180 horsepower and sold in the North American market.
Sizes of Mitas SFT are 900/60R42; 710/60R34; 650/60R34; 710/65R46; 750/65R26 and 580/85R42.
Mitas SFT draws on the performance of Continental SVT farm tires.
Mitas has recently invoked the option to extend the contract, manufacturing Continental agricultural tires for an additional five years through 2019.
Mitas’ Super Flexion Tires compete with the Improved Flexion concept. Their main advantage is the flexibility of variable inflation pressure and optimal performance according to application. Flexible ultra-strong sidewalls allow low inflation pressures for high load carrying capacities, gentle ground handling and higher yields.
SFT is designed for North American original equipment manufacturers and farmers. New sizes of Mitas SFT, Charles City, Iowa, will be available to worldwide markets during the year 2014.
