Effect of restricted access time to pasture on dairy cow milk production,grazing behaviour and dry matter intake
Irish dairy farmers are now targeting a 300-day grazing season in order to increase the proportion of grazed grass in the diet of the dairy cow and optimise the economical efficiency of their business.However,inclement weather conditions in early spring and late autumn can reduce the number of days at pasture for lactating animals,allowing animals restricted access to pasture during these periods may be a method of extending the grazing season.The aim of this experiment was to examine the effect of restricting pasture access time on dairy cow milk production and composition,bodyweight and body condition score change,dry matter intake and grazing behaviour.
