The effect of stage of maturity on the biological availability of magnesium from wheat and orchardgrass fed to sheep
Wheat, a tetany prone forage, and orchardgrass, a non-tetany prone forage, were cut at three stages of maturity to determine the magnesium availability in these forages for lambs. The forages were dried in forced air ovens and ground through a 2.5 cm screen. The nitrogen contents of the forages …

The Influence of Dietary Alfalfa: Orchardgrass Hay and Lasalocid on Nutrient Utilization and Reproductive Performance by Gravid Swine
… evaluate four dietary treatments: corn-alfalfa:orchardgrass hay (CH); CH plus lasalocid (CHL); corn-soybean meal (CS), and CS plus lasalocid. Various buffers, incubation times, buffer pH, and substrate/inocula sources were used in an in vitro anaerobic mixed culture system. A 24 h incubation was …
