NEW RE­SEARCH shows a diet that in­cludes plan­tain means cows don’t pro­duce as much harm­ful ni­tro­gen in their urine, and still make good weight gains.

Re­search by live­stock pro­duc­tion sci­en­tists from the Fac­ulty of Agri­cul­ture and Life Sciences at Lin­coln Univer­sity looked at whether in­cor­po­rat­ing deep-rooted for­age herbs such as plan­tain or chicory into a pas­ture mix would help an­i­mal pro­duc­tion and sus­tain­abil­ity on farms Their work has shown a mix of plan­tain and chicory is great for the en­vi­ron­ment, but plan­tain in par­tic­u­lar is a win-win for dairy farm­ers.

“We were de­lighted to find that the herbage mix­tures re­duced uri­nary ni­tro­gen ex­trac­tion com­pared with the tra­di­tional pas­ture,” says prin­ci­pal in­ves­ti­ga­tor Dr Paul Cheng. “This showed the po­ten­tial for such herbs to mit­i­gate the en­vi­ron­men­tal im­pact of live­stock farm­ing.

“How­ever, while plan­tain mix­tures sup­ported sim­i­lar liveweight gains of the heifers com­pared with tra­di­tional pas­ture, chicory-fed heifers had lim­ited liveweight gains.”

This trial at Lin­coln Univer­sity’s Ash­ley Dene Pas­toral Sys­tems Re­search Farm in Can­ter­bury in­volved short-term au­tumn and spring tri­als us­ing 56 Friesian x Jersey heifers in 2014. The heifers were di­vided into five di­etary treat­ment groups graz­ing in­di­vid­ual swards: 100% chicory; 100% plan­tain; con­ven­tional peren­nial rye­grass­white clover pas­ture; 50:50 pas­ture: chicory; and 50:50 pas­ture plan­tain.

Com­pre­hen­sive mea­sure­ments were taken of both the for­age and an­i­mals be­fore and af­ter graz­ing to record the re­sponses to each of the di­ets.

A sec­ond trial, in 2015, us­ing the same herbs showed that us­ing chicory and plan­tain in a mix­ture with peren­nial rye­grass-white clover at pro­por­tions of 25% and 50% in the diet had the po­ten­tial for use as a mit­i­ga­tion tool to re­duce the en­vi­ron­men­tal im­pact from dairy hei­fer­rear­ing sys­tems in au­tumn and spring. Sim­i­lar to the 2014 trial, liveweight gains of the heifers graz­ing chicory mix­tures were low rel­a­tive to the other groups.

How­ever, sci­en­tists still don’t know what the mech­a­nisms are that de­ter­mine the lower uri­nary ni­tro­gen con­cen­tra­tion and ni­tro­gen ex­cre­tion and say fur­ther stud­ies are needed.
