Cattle producers can benefit from improved operations
Motivated to protect their agricultural investments from the threat of disease outbreaks, many livestock producers – even those on smaller farms – are becoming more aware of ways to improve biosecurity on their farms.
In the summer of 2013, the United States experienced its first confirmed case of porcine epidemic diarrhea virus (PEDv), followed by an outbreak among several swine herds across the northern Midwest.
The disease has the potential to financially devastate producers, and many have started paying attention.
Allen Rice, sales representative at Hartville Feed in Hartville, Mo., said many hog producers across the four-state area have taken steps to implement greater biosecurity practices on their operations.
In terms of biosecurity practices, Rice said that, in general, hog and poultry producers are the appear to maintain the strictest programs.
Rice said disease prevention is the main objective of biosecurity practices. All of these types of operations – beef, dairy, hogs and poultry – exist over all corners of the four-state area.
“When I think of biosecurity, I think that you’re trying to limit exposure to outside diseases, or potential outside pests,” Rice said.
Though biosecurity typically refers to the prevention of disease transmission within a herd or flock, Rice said it can also refer to guarding against pests, such as wild animals, that can transmit diseases.
University of Missouri Extension Southwest Region Livestock Specialist Elden Cole said these outside pests pose a significant threat.
“Always be watchful for wild animals,” said Cole. “These could include animals such as coyotes, raccoons or even stray dogs, which can carry disease.
Cole said he has heard recent stories from farmers about a problematic new species affecting livestock production. Black vultures, also called Mexican vultures, primarily eat decaying animal carcasses. They come onto farms and bring diseases with them.
Additionally, these vultures are capable of attacking small calves, piglets, lambs and goat kids.
No matter the species, Cole said he recommends quarantining any animals that are new to the farm or that have left the farm and returned, such as show animals.
The diversity across operations gives way to various levels of biosecurity practices. Rice said larger operations have more sophisticated biosecurity programs with more animal confinement and tighter controls on human visitors. Meanwhile, smaller operations might have livestock outside rather than in a confined space, which creates the need for other types of biosecurity practices. For example, when hogs are in an outdoor space, outdoor “vectors,” including wild animals and birds are always factors that must be managed.
Hartville Feed is responsible for practicing biosecurity on all of the farms where its employees deliver feed. On certain farms where higher levels of biosecurity are in place, drivers put on plastic booties, step out of the truck, and spray the tires with disinfectant before driving through the gate.
Drivers also follow a standard procedure that prevents them from climbing on feed bins, where the potential to spread disease from farm to farm through contaminating feed and equipment might exist.
The cardinal rule for Hartville drivers is that they are not to enter barns at any time.
In the swine and poultry industry, integrator companies may outline biosecurity principles in a policy or contract, but whether biosecurity procedures are put in place by a company or by an individual producer, Rice said he thought it didn’t make much of a difference in the long run, as long as the practices are consistent.
Rice said, however, that he thought most farmers understand biosecurity, just to differing degrees.
“It’s going to involve your livelihood,” said Rice.
When biosecurity fails to be a priority, disease can financially ruin producers on all types and sizes of operations.
“If the animals die or if they have to quarantine them to where they can’t come through – that’s a direct impact on (the producer),” said Rice. “It’s something that everybody needs to be aware of, and I think most people are.”
