Investigation of factors influencing herbage intake rate of grazed grass by lactating dairy cows - DS0408

Objective
The aim of studies proposed in this project is to obtain fundamental information on sward factors which influence herbage intake with lactating dairy cows, particularly with regards to maximising herbage intake by high genetic merit lactating cows. Previous research in this area has generally been constrained by the fact that considerable emphasis was give to achieving a compromise between individual animal performance and sward productivity. However, with constraints on milk output in the form of milk quotas, performance and sward productivity. However, with constraints on milk output in the form of milk quotas, and increasing trend towards higher individual cow performance, coupled with a general move within the EC toward extensification, it is now more appropriate to concentrate on specific sward factors which will maximise herbage intake, and hence animal performance, whilst accepting reductions in output per hectare. Nethertheless the aim should be to achieve this with minimum sacrifice of utilization efficiency.
