This study investigated the dose-dependent response in lamb meat of stable nitrogen isotope ratio to the dietary proportion of legumes, and the ability of the nitrogen isotope signature of the meat to authenticate meat produced from legume-rich diets. Four groups of nine male Romane lambs grazing a cocksfoot pasture were supplemented with different levels of fresh alfalfa forage to obtain four ...

A nineteen year trial at Lake Tekapo compared the longer term trends of over-drilling legume and grasses into either previous undeveloped tussock country or following a previous legume phase. Tall oat grass (from summer sowing) and cocksfoot (from spring sowing) were the most successful of the sown grasses. They remained a low proportion of the swards but greater with prior herbicide treatment,...

DURING the past few years, an extended study has been made in these laboratories of the chemistry of certain constituents of the forage grasses, the nitrogenous substances and the fats and waxes having received particular attention. Samples of a number of grasses of pure strain and known history being available, the opportunity was taken to examine the cell-wall substances of certain of these. ...
