Partial replacement of ryegrass and clover herbage with chicory to alter urination behaviour and soil nitrogen loading of grazing dairy cows

Chicory (Chicorum intybus L.) is a high moisture, low fibre forage, traits that have been identified to influence protein degradation and urea metabolism. Our recent study revealed sole diets of chicory increased urinations diluted the concentration nitrogen in urine. The purpose this was compare effect feeding lesser proportion diet, impact diurnal changes chemical composition on urinary concentration. Thirty-six dairy cows were evenly divided into nine groups, randomly allocated either ryegrass/white clove only (RGWC), plus morning allocation (CHAM) or afternoon (CHPM). inclusion by up 69%, resulting 33% mean decline UN concentration, independently time allocation. While farmers are encouraged adopt mitigation strategies reduce N losses, there value offering range forage options improve adoption. These results show moistures forages including potential leaching through urination behaviour loading.
