After a hard freeze, there could be questions regarding prussic acid in sorghum. Prussic acid poisoning is more of a concern when grazing sorghum than when harvested for hay or silage.
Many Kansas cattle operations rely on some type of harvested feed to use in the winter months. Forages in the sorghum family are prone to two different problems for feeding cattle, nitrate poisoning and prussic acid poisoning. Learn about how to test for these and key characteristics of each toxin.
In last week's eUpdate, nitrate and prussic acid poisoning was discussed when feeding cattle certain types of forages. In this follow-up article, we share information on the different tests available and how to collect a representative sample.
While sorghum is a valuable forage crop, sorghum species can produce prussic acid, which can be toxic to livestock. The potential for toxic levels of prussic acid is affected by several different factors. If proper management occurs, sorghum can be a safe and beneficial forage crop.
Many Kansas cattle operations rely on some type of harvested feed to use in the winter months and common among those sources is forage sorghum, millets, sorghum-sudangrass, and sudan. When feeding cattles, forages in the sorghum family are prone nitrate poisoning and prussic acid poisoning. Learn the difference and how to test for these before a problem occurs.
Freezing temperatures change plant metabolism and composition, and different forage species respond differently to cold stress. Damaging frosts significantly reduce forage quality in most forage species and can create possible feeding-related issues for livestock.
Freezing temperatures change plant metabolism and composition, and different forage species respond differently to cold stress. Depending on plant species, these changes in metabolism resulting from freezing temperatures can create possible feeding-related animal disorders.
