Title: METHODS OF MINIMISING ENVIRONMENTAL NITROGEN IMPACTS FROM FARMED ANIMALS
Abstract:
The invention relates to methods of minimising environmental impacts from farmed animals, such as dairy animals. More specifically, the invention relates to a method of minimising the nitrogen load from animals by the steps of: (a) testing animals to identify individual nitrogen load; and, (b) manipulating animal gene or genes in order to reduce the average nitrogen load. By identifying animals with a low average nitrogen load, they may then be manipulated and appropriate management used, for example, by grazing such animals in certain land areas that are more at risk of nitrogen emissions to the environment or by breeding from these animals. Animals with a high average nitrogen load could be grazed in areas that have a lower risk of nitrogen emission or could be culled altogether.
