DIFFERENTIAL GENE EXPRESSION IN EWES DIVERGENT FOR RESPONSE TO NITRATE TOXICITY

 (WYO-416-07)


Many forage crops become toxic during drought conditions due to high concentrations of nitrate. Nitrate toxicity is often observed in cattle and sheep populations during periods of drought. Symptoms and severity of nitrate toxicity vary widely, and include decreased performance, hormonal imbalances, abortion, and in many instances, death. The purpose of this study is to identify genetic differences between animals that are more and less tolerant to consumption of high levels of nitrate.
