Description

The greatest environmental risk from wintering sites is the potential for water contamination from runoff carrying nutrients, pathogens and sediments. Also, excessive nitrogen levels in the soil at the site increase the risk of nutrients leaching into groundwater sources. Elevated soil nutrient levels can result in subsequent crop production concerns such as lodging or high feed test nitrate-nitrogen levels. Elevated soil nitrogen levels combined with high soil moisture conditions can result in gaseous losses of nitrogen, and ammonia emissions from manure may cause odour concerns.

Description

Producers are always encouraged to have their beef cow feed programs set well in advance of the winter. This is even more important when planning through a challenging time, one that may require extra feed for extra animals due to volatile or weak markets. In times of high feed prices, planning can also help producers manage and potentially reduce overall winter feed costs.

Nitrate poisoning and feeding nitrate feeds to livestock

While nitrates (N03) are not very toxic to animals, nitrites (N02) are toxic. In ruminant animals such as cattle, sheep, and goats, nitrate is converted to nitrite by bacteria in the rumen. When... More ≫

Description

While nitrates (N03) are not very toxic to animals, nitrites (N02) are toxic. In ruminant animals such as cattle, sheep, and goats, nitrate is converted to nitrite by bacteria in the rumen. When ruminants consume a high nitrate feed, both nitrate and nitrite can accumulate in the rumen, and nitrate poisoning occurs when the nitrite level in the rumen exceeds the capacity of the microbes to convert it to ammonia. This fact sheet addresses some common questions about nitrate poisoning and discusses how to reduce the risk of nitrate toxicity.
