A trial was performed with castrated male hogs of the Belgian Landrace x Belgian Landrace, in the finishing stage, from 23 Kg. of weight to 90 Kg., during the 101 days of the test; feed consumed was based on corn-soybean with an average content of 5 ppm aflatoxin B1 (AB1) and 50 ppb of Ochratoxin; a parallel trial was carried with added TOXIBOND as a sequestering agent, and; a third one, with the mycotoxins in question absent was verified in the laboratory. 20 animals per treatment...

Mycotoxins are fungal metabolites that can reduce performance and alter metabolism of livestock and poultry (Wannemacher et al., 1991). The pathological states arising from the consumption of feeds contaminated with mycotoxins are referred to as mycotoxicoses. Mycotoxins can be formed in the field preharvest and may continue to be formed under suboptimal storage conditions post-harvest. High moisture content often predisposes feedstuffs to fungal growth and mycotoxin formation....

Mycotoxins are toxic substances that disrupt the normal function of the animals' immune system. This leads to significant negative economic impacts. The effect on the immunity and subsequent impacts in pigs are discussed here.
The economic viability of modern pig production farms is affected by numerous factors. Amongst them, exists some that cannot be controlled by the farmers, namely the agricultural products and the meat's...

Feed is the mostly costly component of a swine operation. The nutritive value and relative cost of feed plays a crucial role in maximizing returns. However, the producer also needs to consider the condition of the feed. Feed contaminated by moulds can make a serious dent in the productivity of a given operation, with effects ranging from feed refusal to serious illness. Though moulds may diminish the nutritive value of strain on which they grow, the more serious concern is with...

Mycotoxins in straw could pose a particular threat to the health of pig herds this year, according to James Hall of the ACMC pig breeding company.
The late, wet harvest means straw has been both in short supply and of poor quality.
"While many producers are aware of mycotoxins in cereals, the danger from mouldy straw can be easily overlooked," he said.
The first signals could be an increase in the number of returns to service, extended weaning-...

The University of Manitoba recommends feed testing and close monitoring of pigs to avoid problems associated with fusarium head blight infected grains. Fusarium head blight has been identified throughout out much of Manitoba this year with the highest levels reported in the Interlake and in southeastern Manitoba. Dr. Martin Nyachoti, an associate professor with the University of Manitoba's Department of Animal Science, says the main concern when feeding fusarium...

The optimum solution is to buy clean grain for swine and feed the contaminated grain to cattle. Feeder cattle should be able to safely consume levels five to 10 times higher than swine. If contaminated corn must be fed, the following table lists maximum levels in swine diets for vomitoxin and zearalenone.

Pearling Fusarium-Contaminated Barley Yields A Feedstuff Suitable For Use In Starter Pig Diets While the full extent of the fusarium problem in the 2005 Manitoba cereal grain crops has yet to be determined, preliminary reports highlight the potential for significant infection rates. For pig producers, this could mean another season of coping with DON. The mycotoxin DON (deoxynivalenol or vomitoxin), when present in swine diets above 1 to 2 ppm, can suppress feed intake and...

Swine producers who source cereal grains from Manitoba this year, especially late harvested wheat, are being encouraged to have samples tested to avoid potential problems associated with the mycotoxins produced by fusarium head blight. Fusarium head blight is a fungal disease that infects cereal grains, including wheat, barley, oats, trictcale and corn. The disease, which attacks the head infecting the plant’s kernels, thrives under warm moist conditions. Wheat is particularly...

With a wet start to the Ontario growing season, the possibility of pre-harvest infection of wheat, barley and other small grains by Fusarium fungi is high this year. In addition to reducing quality and yield, Fusarium also produces mycotoxins, such as deoxynivalenol (DON) and zearalenone (ZONE), which contaminate the cereal crop. These mycotoxins, at high enough levels, produce toxic effects in livestock, especially swine. Feeding wheat to...

Manitoba swine producers are being advised to exercise additional vigilance this year to avoid the potential consequences of feeding mycotoxin infected feed grains. Fusarium head blight is a fungal infection that affects primarily cereal crops, most notably wheat. Weather conditions ideal for the development of the disease were prevalent this year during the most vulnerable stage of crop development resulting in widespread infection of red spring wheat crops in Manitoba....

Deoxynivalenol (DON) is a mycotoxin produced by fungi which may contaminate cereal grains, including barley and wheat. The contamination is especially problematic when wet, warm conditions prevail during the growing season. The ingestion of grain that is severely contaminated by DON will cause overt symptoms such as vomiting (hence the common name “vomitoxin”). Less dramatic, but more frequently observed symptoms, reduced feed intake and growth, will result when pigs consume feed with a lower...

Some molds produce mycotoxins. The molds can invade feed and produce toxic compounds that contaminate the feed. Molds can infect grain in the field, during harvesting, handling, and storage. More than 200 mycotoxins have been identified, but only a few are believed to affect swine performance. Risk to the pig from mycotoxin-contaminated feed depends on the age and health of the pig and level of toxin in the feed. The most severe effect is death, but low levels of mycotoxin can hurt pig...
