Other claims from this paper (15)
- Observation From late May to mid-September the dry matter content of the bluestem pasture grass varied from 32.7 to 39.0 percent.
- Observation From late May to mid-September the protein content of the grass dry matter varied from 6.77 to 8.97 percent.
- Observation From late May to mid-September the crude fiber content of the grass dry matter varied from 28.46 to 32.32 percent.
- Observation After September the protein content of the grass decreased to 4.31 percent.
- Observation After September the crude fiber content of the grass increased to about 34 percent.
- Observation During the winter grass protein decreased further to 2.56 percent without a corresponding increase in crude fiber.
- Observation Variations in the N-free extract content of the grass were small and irregular throughout summer and winter.
- Observation The apparent digestibility of dry matter of the grass decreased from about 58 percent in September to about 41 percent in November.
- Observation The apparent digestibility of protein of the grass decreased from about 54 percent in September to about −16 percent in November.
- Observation The apparent digestibility of crude fiber of the grass decreased from about 69 percent in September to about 62 in November.
- Observation The apparent digestibility of N-free extract of the grass decreased from about 61 percent in September to about 41 percent in November.
- Observation During July to September there was practically no change in the digestibility of the grass nutrients, except for protein and ether extract.
- Observation The digestibility of the dry winter grass was somewhat higher in December than in January and February.
- Intervention effect Cottonseed cake supplements improved the digestibility of both winter grass and prairie hay rations.
- Observation The dry matter of the late winter grass was less digestible than that of cured hay.
