Mold can grow on grain in the field, storage or feed bunk. Molds and mycotoxins can harm cattle and lower the nutritional value of feeds. The three common molds that produce mycotoxins and grow on grain are Aspergillus sp, Fusarium sp and Penicillium sp.

2018年12月19日 · Ingestion of moldy feed or hay can potentially cause mycotic (fungal) abortion, respiratory effects, decreased feed consumption and rate of gain, and digestive problems. Additionally, molds can have effects on humans that handle the moldy feed.

2022年11月4日 · While livestock producers know that moldy grain and forage are not ideal feedstuffs, they also know that stored feed occasionally contains a small amount of visible mold, and that their animals consume it with no obvious adverse effects. The question arises, how much mold is too much for a feed to be unsuitable for animals?

2018年12月20日 · While mycotoxins (mold poisons) are the main concern, molds themselves can adversely affect health and productivity of cattle. Ingestion of moldy feed or hay can potentially cause mycotic (fungal) abortion, respiratory effects, decreased feed consumption and rate of gain, and digestive problems.

2022年10月11日 · Moldy grain is the main consideration, moisture content is another. While livestock producers know that moldy grain and forage are not ideal feedstuffs, they also know that stored feed occasionally contains a small amount of visible mold and that their animals consume it with no obvious adverse effects.

Moldy corn is not an uncommon occurrence and does not preclude the grain from being harvested as livestock feed. However, identifica-tion of the mold and analysis for any associated mycotoxins is essential to formulating diets that are safe for all classes of beef cattle.

2020年4月29日 · If grain or hay is over 15% moisture, it should be used first so it doesn’t sit out for too long. Make sure new barns are constructed to prevent conditions optimal for mold growth. Some mold development in feed is unavoidable. Avoid giving moldy feeds to more vulnerable livestock such as horses or young or lactating animals.

2020年4月14日 · Significant mold in feed can result in production losses between 5% and 10%, even without the presence of mycotoxins. Certain species of fungi can increase activity and temperature when hay is wet, thereby increasing the risk of spontaneous combustion.

2010年1月20日 · Molds are organisms and mycotoxins are chemicals produced by certain species of molds that are toxic to animals. Visibly moldy grain may or may not have mycotoxins and mycotoxins can be found on feeds that are not visibly moldy. Moldy corn that is not contaminated with mycotoxins is not as nutritious as clean corn.

2010年4月12日 · Grain mold and dust could cause respiratory problems. Anyone harvesting, drying or handling moldy grain should use respiratory protection, according to Ken Hellevang, agricultural engineer with the North Dakota State University Extension Service.
