Nitrate poisoning in cattle grazing crops

Abstract

Extract

Although nitrate/nitrite poisoning of cattle, sheep and pigs has been recognized in New Zealand for many years, it has become more widely publicized in the past 2 years owing to the greater prevalence of poisoning and the involvement of hitherto unsuspected crops, notably ‘Grasslands Tama’ ryegrass. In this review, experiences with recent outbreaks of nitrate poisoning are compared with published observations. Throughout this paper the disease will be referred to as nitrate poisoning.
