Operational research study of forage conservation systems for cool, humid upland climates. Part 1: Description of model
TL;DR: In this paper, an improved operational research model is described for studying the economics of forage conservation systems, particularly for cool, humid, upland climates, covering the whole process, from growth of grass, through all the conservation operations, to evaluation of conserved forage for feeding ruminants.

The feeding value of cereal straws for sheep. III. Supplementation with minerals or minerals and urea
P.T. Doyle,S.B. Panday +1 more
TL;DR: In this paper, the effects of supplementation with a complete mineral mix or with the mineral mix and urea and sulphate on the intake and digestion of three straws by sheep was examined in six experiments.

Chemical composition of ryegrass (Lolium perenne L.) and prairie grass (Bromus willdenowii Kunth) pastures
TL;DR: Herbage chemical composition, sward botanical composition, and animal intake were measured monthly for a year in pastures dominated by Lolium perenne (ryegrass) or Bromus willdenowii (prairie grass); there were significant seasonal changes in herbagechemical composition for all the elements measured except sodium.

Management opportunities for boosting productivity of cool-temperate dairy farms under climate change
TL;DR: In this article, the effects of stocking rate and seasonal calving times on pasture and milk production under short and long term climate changes on dairy farms in Tasmania, Australia were assessed.
