LARGE SQUARE BALERS--Several upgrades and innovative options are available on the new Case IH LB333 and LB433 large square balers. The 2009 models provide a more consistent bale shape and length, and improve bale density by up to 5 percent. And an improved best-in-class knotter reduces stops and increases time in the field.

Company offers new semen straws in new size

Genex Cooperative, Inc., Shawano, Wis., uses effective semen processing and evaluation procedures; research and development; and high fertility standards to produce quality semen. Now, Genex will begin marketing all dairy semen in one-quarter cc straws.

Improved fertility is the basis of the transition to one-quarter cc straws. Genex has conducted extensive field trials with the results published in the scientific journal, Theriogenology. The field trials show conception rates to be significantly higher for services performed with one-quarter cc straws compared to semen packaged in the traditional half cc straws.

The one-quarter cc straw is simple to incorporate into current breeding programs as several Genex semen products--GenChoice and European semen--are already available in the one-quarter cc straw package. Semen handling and thawing techniques remain the same, though a one-quarter cc or universal artificial insemination gun is required.

The transition to one-quarter cc straws is one more way Genex is creating the cattle pregnancies today's producers need.

New livestock pest control available in smaller bottle

Bayer Animal Health has introduced its new Tempo SC Ultra Pest Control Concentrate (11.8% beta-cyfluthrin) in a convenient 32 mL bottle. This 5th-generation pyrethroid insecticide has long been an effective broad spectrum tool to control indoor, outdoor, and wood-infesting pests in and around livestock premises, and it is effective on more than 60 different pests.

With the availability of Tempo SC Ultra in a 32 mL bottle, smaller livestock operations and farms can now buy just what they need, providing a very economical and convenient option for pest control. Tempo SC Ultra can be used in animal housing, including barns, horse stables, and other animal quarters to control crawling, flying, and wood-infesting insect pests.

"Tempo SC Ultra is now available in a smaller size, at just a fraction of the cost of the large package. Operations such as smaller horse and cattle farms can now buy just the right amount of Tempo SC Ultra, providing them increased flexibility in their pest control programs," says V. Bruce Steward, Ph.D, Marketing Product Manager, Livestock Insecticides for Bayer Animal Health.

Beta-cyfluthrin, the active ingredient in Tempo SC Ultra, is a stabilized pyrethroid insecticide that acts both on contact and ingestion. Tempo SC Ultra provides effective knockdown of a broad spectrum of insect pests. It delivers successful control in a liquid suspension-concentrate formulation, providing even dispersal during application. The active ingredient stays in suspension without re-agitation.

The 32 mL size will make 2 gallons of mixed spray and treat 2,000 square feet of insect-resting surfaces. There is no measuring needed--simply pour the entire contents of the container into 2 gallons of water, shake, and spray.

New intranasal vaccine protects calves as early as three days of age

Intervet/Schering-Plough Animal Health, Millsboro, Del., recently announced the availability of Onset 5 IN, the first intranasally administered, five-way modified-live virus (MLV) vaccine for healthy cattle 3 to 8 days and older.

Onset 5 IN is designed to stimulate at the site of infection an immune response to Bovine Virus Diarrhea (BVD) Type 1 and Type 2, Infectious Bovine Rhinotracheitis (IBR), Parainfluenza3 (PI3) and Bovine Respiratory Syncytial Virus (BRSV)--the costliest diseases impacting beef and dairy herds.

"Onset 5 IN is changing the way the beef and dairy industries think about the immune development of calves and, subsequently, the ability to help beef and dairy calves get off to a strong immunological life," says Dr. Scott Nordstrom, Manager of Veterinary Technical Services for Intervet.

"The bovine fetus has a much more mature immune system than originally believed," Dr. Nordstrom said. "In fact, the immune system of the fetus is functional at approximately 170 days of gestation. We've also learned that development of the immune system is independent of antibody production, meaning the immune system can respond to an appropriately delivered vaccine without antibody interference. This knowledge underpins the developmental science of Onset 5 IN and is why the intranasal route of administration of Onset 5 IN is so important."

Until recently, immunology models were based on research conducted in mice, which have a different type of immune development. New research specific to the bovine immune system shows a more effective and rapid immune response can safely be generated when the vaccine is delivered to mucosal surfaces, such as the nasal mucosa, even in the youngest animals.

This is why Onset 5 IN is delivered through the nose. Intranasal vaccination more closely mirrors the route of real-world infection: More than 95 percent of disease-causing agents enter through the nose, causing primary respiratory disease and often secondary infections. The intranasal administration of Onset 5 IN allows for a more rapid immune response. The vaccine is delivered straight to the mucosal surfaces where infection occurs rather than taking a systemic route.

Emerging science shows vaccine delivery to the mucosal surface also may be an effective strategy for avoiding maternal antibody interference (protection passed to the calf from the dam's milk that can prevent an immune response to vaccination). Research shows if the newborn calf's immune system is stimulated properly by targeting the appropriate mucosal surfaces, a response will be initiated regardless of maternal antibody presence.

"Studies prove even the youngest animals can demonstrate a significant immune response when vaccines were delivered to the appropriate mucosal sites," Nordstrom says. "Onset 5 IN is targeted directly to the appropriate mucosal sites, delivering direct contact between nasal mucosa and respiratory lymph tissues and the vaccine antigens."

Intranasal administration of Onset 5 IN is a less stressful form of vaccine administration.

Onset 5 IN is designed for use in both dairy and beef cattle. The vaccine was uniquely developed to address the immune challenges of the most at-risk groups of cattle--newborns (at 3 days of age) and animals under high stress, such as weaned calves and new arrivals post-transport.

For dairy operations, Onset 5 IN may be utilized for newborns and calves entering calf ranches or heifer-grower operations; pre-weaning before leaving the calf hutch; in the face of disease outbreak or impending transportation stressors; in fresh cows; and as a preventive measure pre-shipment.

For beef operations, Onset 5 IN may be utilized for calves 3 to 8 days of age and older; at branding or weaning; upon arrival of stocker and feeder cattle to induce a rapid immunological response in the face of high stress, and as a preventive measure pre-shipment.

Onset 5 IN is available in 5-, 10- and 50-dose presentations and features a unique glyceride-based BluShadow® diluent that aids in the retention of the vaccine on nasal mucosa. Vaccination consists of a 2-mL dose into one nostril or 1-mL administration into each nostril.

Onset 5 IN is available through veterinarians or animal-health suppliers.
