Climate, nitrogen and grass. 2. The influence of light intensity, temperature and nitrogen on vivo digestibility of grass and the prediction of these effects from some chemical procedures.

Abstract

For part 1, not numbered, see Abst. 4271, Vol. 37. 2. Digestibility of forages grown at different in-tensities of light, temperatures and amounts of N fertilizer was estimated with wethers. The different factors affected chemical composition more than digestibility. Greater intensity of light increased digestibility and higher temperature decreased it. N fertilizer increased it but not significantly. Digesti-bility was less during stem formation. For prediction of digestibility in vivo by different chemical procedures, true digestibility in vitro estimated from digestibility of cell walls was the most accurate.-T. W.
