It was found that the yield of dry matter in the hay was about four times that of the grass which was cut eight times. The per cent, of protein in the grass cut eight times was about three times that in the once-cut grass. This experiment shows that our pastures in their short herbage yield a much higher proportion of muscle-making nutrients than is obtained from grasses which are allowed to mature, but that much the largest returns are secured by allowing them to ripen. (554) 259. Changes in grass during ripening At the Illinois Sta- tion, 2 Hunt studied the effects of maturity on tlie yield and com- position of several forage plants. Timothy was examined at four periods covering about one month" in all, beginning June 25, when the plants were in full bloom. The yield of hay and the total nutrients per acre for each of the four periods are given in the table at the end of this Article. It wUl be seen that, on the whole, there was a steady increase in the weight of the crop as the plants progressed toward maturity. We observe only a slight increase in the total protein content aft«r the first cutting. Between the first and last cuttings the crude fiber increased more than 300 pounds and the nitrogen-free extract more than 350 pounds, while the ether extract was reduced in total quantity as ripening progressed. It appears, then, in this 1 Bui. 141. » Bui. Please note that these images are extracte
