Fast-acting BRD treatment

At World Dairy Expo in Madison Wis., last month, Merial spotlighted Zactran, a new antimicrobial for the treatment of bovine respiratory disease in heifers from birth to 20 months.

Zactran, the first macrolide introduced to the market since 2005, takes just 30 minutes from the time of subcutaneous injection to reach a therapeutic level in the lungs, says Tom Van Dyk, a veterinarian with Merial.

It remains at that level for 10 days, making it ideal for both treatment and control of Mannheimia haemolytica, Pasteurella multocida and Histophilus somni in nonlactating dairy cattle and beef.

Zactran has a 35-day meat withdrawal requirement. Because a discard time has not been established for milk, the product should not be used in lactating cattle.

Zactran comes packaged in bottles that are encased in a plastic protector that makes breakage unlikely, even if dropped on concrete floors. The bottle/protector combination can be hung upside down for continuous use chuteside. Labeling is configured so treatment directions can be read right-side up even when the bottle is hung upside down.

‘A new way to wash’

DeLaval introduces "a new way to wash" with a Reduced Temperature Detergent (RTD) for milking system cleaning.

The product could revolutionize dairy sanitation, the company told Expo visitors, since it requires a water temper-ature of just 113°F to properly clean pipelines and milking units. This offers tremendous water heating savings over conventional cleansers that require a temperature of 167°F.

The lower-temperature water may also put less stress on sensitive components such as teat cup liners and rubber gaskets and help extend their life span, say DeLaval engineers.

DeLaval has applied for a patent on the RTD technology. RTD is moderately priced between low-end, generic detergents and premium grade branded products.

Pioneer Hi-Bred launches BMR silage hybrid

At its Expo booth, Pioneer Hi-Bred highlighted its first entry into the brown midrib (BMR) corn silage market with P1376XR, a 113-day hybrid available in limited quantities for the northeast U.S. in 2012.

"P1376XR combines the digestibility you expect from a BMR with tremendous yields, high starch, strong drought tolerance and a robust disease and pest package," says Kyle Whitaker, Pioneer senior sales and marketing manager for global forages.

The new hybrid features standability without the yield drag typical of BMR hybrids, he says. It comes complete with Herculex XTRA for above- and belowground insect protection as well as the Roundup Ready Corn 2 trait and the LibertyLink gene.

Additional BMR hybrids will be available from Pioneer in 2014.
