Interesting paper and asks some important questions on timing around Feed - if the animals are only having a small feed would these affects be prevalent - i.e does the Greenfeed system have an inherent fault with being used to screen for genetic selection. 
With respect to acknowledgements is this a GRA study or a consequence of our core programme? if it is the latter then I would expect thae acknowledgements to reflect that and our funding acknowleged first. 

We approve the paper with these issues noted and responded to.
