Effects of surface type in an uncovered stand-off pad system on comfort and welfare of non-lactating dairy cows during winter

Al-Marashdeh, Omar; Cameron, Keith C.; Bryant, Racheal H.; Chen, Ao; McGowan, Briar; Gillé-Perrier, C.; Carey, Peter; Chrystal, J.; Hodge, Simon; Edwards, Grant (Elsevier on behalf of International Society for Applied Ethology (ISAE), 2019-02-01)

The objective of this study was to investigate the effect of stand-off surface type on cow lying behaviour, cleanliness and lameness. One hundred and sixty Friesian × Jersey crossbreed, pregnant non-lactating dairy cows ...

Production, profit and nitrogen flows in irrigated dairy systems representing different industry development pathways: The Pastoral 21 experience in Canterbury

Chapman, D. F.; Dalley, D. E.; Edwards, Grant; Cameron, Keith C.; Malcolm, B. J.; Clement, A.; Romera, A. J.; Pinxterhuis, I. B.; Beukes, P. C.; Di, Hong J.; Bryant, Racheal H.; Curtis, J. (Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-08-26)

Future development pathways for irrigated dairy farms in Canterbury operating under stricter nitrogen (N) loss limits were compared in two farmlets over four years. One represented the traditional pathway of intensification ...

Dry matter intake and body condition score change of dairy cows grazing fodder beet, kale and kale-oat forage systems in winter

Edwards, Grant; de Ruiter, J. M.; Dalley, D. E.; Pinxterhuis, I. J. B.; Cameron, Keith C.; Bryant, Racheal H.; Di, Hong J.; Malcolm, Brendon J.; Chapman, D. F. (NZGA, 2014)

Crop dry matter (DM) yield, DM utilisation and body condition score (BCS) of dairy cows were measured over two winters on an irrigated stony, free-draining Balmoral soil for three crop grazing systems: fodder beet (FB); ...

Herbage dry-matter yield and nitrogen concentration of grass, legume and herb species grown at different nitrogen-fertiliser rates under irrigation

Martin, Kirsty; Edwards, Grant; Bryant, Racheal H.; Hodge, Miriam; Moir, James L.; Chapman, D.; Cameron, Keith C. (CSIRO Publishing, 2017)

An important goal in dairy systems is to increase production while achieving environmental targets associated with lower nitrate leaching from soils. One approach is to identify forages that grow more at a given level of ...
