Swine Health Research Just as the Doctor Ordered

Pig health is important in protecting the herd and the bottom line. Three threats to pigs include Brachyspira, Porcine Reproductive and Respiratory Syndrome (PRRS) and Porcine Epidemic Diarrhea virus (PEDv). Brachyspira can be deadly and research is being done on its antibiotic resistnce to look at what drugs are effective against it. This will help veterinarians in choosing the dosage and drug, reduing mortality and it will help producers by reducing costs through...

Feed Research Has Finger on the Pulses

Pulse crops like lentils, field peas and faba beans may be a cheaper option for swine feed. These ingredients are highly available in Canada and though often used for human consumption, when they are downgraded they could be a cheap diet replacement for pigs, but more research needs to be done on the nutritional value. Starch in pulse crops is different than cereal crops and is digested a lot slower...

The Ceiling’s the Limit in Barn Repair Options

Barn deterioration happens at a rapid pace in the swine industry due to conditions including high moisture, varying temperature, corrosive gases and the presence of microorganisms and dust. Components like the walls, attics, ceiling and eaves are often affected. Renovations are costly and often need to be done every few years, so research is focusing on ways to prolong the life of the barns. Concrete, wood and metal are the...

Grasping at Straw to Boost Sow Milk Yield

Increasing sow milk yield is an important area of research since it helps with piglet growth. Sows are often aggressive due to restricted feeding so increasing satiety was investigated to see if performance was improved. Processing of straw improved the energy digestibility, with stronger effects found in oat straw compared to wheat straw. Providing diets with 10% straw improved satiety in the sows and higher weaning weights were seen in...

Fed Up With High Feed Costs? Chew On This

Feed costs are one of the main expenses in swine production, so a lot of research has been done to help reduce this constant strain on producers. Feeding low, constant net energy diets is a cheaper alternative to feeding higher net energy levels in grow out hogs. This is true when the lower dietary energy density can be compensated for by an increased feed intake. This can be difficult for...

Good Things Come in 3D for Pork Researchers

3D vision systems can be used to rapidly and objectively assess hog carcass quality. The current evaluation system focuses on fat and lean carcasses, but the amount of each is not of too much importance, it's the location of each that really matter. The belly is the most expensive part of the hog and it is preferred to have higher fat there. The 3D system uses images to gauge the...

Pigs in Space

Space allowance can impact many areas of pork production including social interaction, behaviour, stress and productivity. Often weaner pigs are given less space allowance due to their size but this may not be adequate. Crowding occurs near the end of the nursery phase as the piglets are at their largest size. In late nursery, overlying is not normally done by the pigs and more normal behaviours are seen with a...

On Farm Automation Takes Off

Collecting data is an important part of farming with trends moving towards precision farming, though it can be a time consuming process so new ways of doing this task are being looked into. Automation including 3D vision technology and individual water recording systems have a lot of potential and can help in genetic selection, animal welfare and boosting efficiency. A 'smart drinker' can help identify sick animals using changes in...

Rapid PEDv Test Earns Top Marks

A faster, easier and cheaper method to detect Porcine Endemic Diarrhea virus (PEDv) is being developed that uses a molecular diagnostic platform called the Accutas™. This test can be done on the farm with very fast results (1-2 hours) so it is cheap to do and not time consuming. It detects if pathogenic RNA or DNA are present in a fecal or blood sample. This device works for porcine circovirus...

Mycotoxins and the Immune System

Mycotoxins are produced by mould that grows on grains and are toxic and cause diverse effects to livestock. Dilution and feed additives can be used to try to mitigate the effects but their effectiveness is not clear and it increases costs. One of the many symptoms of mycotoxin consumption can be reduced immunity and may even affect the efficacy of vaccinations. Deoxynivalenol (DON) is a common mycotoxin that has negative...
