Abstract
Leafy green vegetation is a source of apparently still unidentified nutritional factors. The grass factor for poultry usually gives a growth response on practical type rations (Scott, Gilsta and Goffi, 1951; Scott, 1951; Scott and Jensen, 1952; Slinger, Pepper and Hill, 1952). Patterson (1937) and McCandlish (1939) increased gains in steers when sprouted corn was added to the ration with the latter researchers showing 15 to 20% increase in gain. However, McCandlish and Struthers (1938) and Thomas and Reddy (1962) showed that the addition of sprouted corn had no significant effect upon ration digestibility. It was the objective of this research to investigate further the effects of adding various levels of “oat grass” to low and high concentrate rations for beef steers using a natural source of protein. Growth of Oats Grass. Oats (avena sativa) of approximately 85% germination were used for the production of grass. The whole oats were soaked in water for 4 hr., then germinated for 48 hr., transferred to culture baskets and placed in a dry culture vat for 6 days. Copyright © 1969.
