Getting ahead of pests that may limit animal productivity is necessary for proper livestock management this spring and summer.
Normal to high insect pressure is expected this season, Bayer HealthCare LLC Animal Health specialists say, and "the best defense against pests is a good offense," says Dr. Larry Hawkins, senior technical services veterinarian at Bayer HealthCare Animal Health.
Using a four-point pest management system is an ideal strategy to protect livestock operations from pests and the damage they can cause, including disease transmission, disrupting feeding and ultimately reducing animal weight gain.
The key to an effective pest management strategy is understanding the type of pest, its feeding habits, breeding areas and preferred resting spaces, Bayer says. This is true whether you have a beef, dairy, poultry or swine operation.
Hawkins recommends dividing a producer's entire operation into four treatment areas:
• On-Animal – Animals are ground zero for pest damage. On-animal treatment targets pests that want to take blood meal from your livestock, such as horn flies, mites and ticks. On-animal treatments include ear tags, pour ons, on-animal sprays and dusts.
• Facility – Facility and pen premise treatments allow you to target pests in areas where your livestock feeds and rests. This creates a prime location for pests to pass from one animal to another. Treating your facilities can help reduce the number of pests bothering your livestock. For cattle and swine, these include baits and sprays. For poultry, they include sprays and dusts.
• Environment – Pests may use the areas beyond the immediate housing facilities to breed. Treating potential pest-breeding areas that surround your livestock buildings, horse stables and feed storage areas may play a significant role in reducing the pest populations. For cattle and swine, these treatments include baits, sprays and dusts. For poultry, these include sprays.
• Feed-Through – Several species of flies lay their eggs directly in manure. Feed-through insecticides kill fly larva as the eggs hatch, before they can mature and continue the cycle. The use of an oral larvicide can be a proactive effort in disrupting the fly's lifecycle.
In addition to selecting quality pest management products, livestock management through rotation can help minimize the development of resistance in insecticides as pests can develop reduced susceptibility to an active ingredient over time.
To help prevent this, consider rotating to a product that uses a different mode of action every year or so. An effective rotation strategy alternates between products from completely different MOA groups, not just between active ingredients from the same MOA group.
"Use the products that fit your management style, but be sure to keep your method of fly control active," says Manager of Farm Hygiene Products at Bayer HealthCare Animal Health Bruce Brinkmeyer. "That will go a long way in bolstering your defenses and ensuring an effective pest control program."
