Harrison, B. J.; Thatcher, A. P.
A study of the grazing habits of sheep on the winter range of southwestern Wyoming showed the grass needleandthread (Stipa comata) to be the key forage species. This was true even with a snow cover of 8 inches. Other grass species also contributed a large amount to the sheep diet. Low rabbitbrush (Crysothamnus viscidiflorus) was the most preferred shrub species. Very little use was made of the other shrub species.

Kirk, W. G.; Shirley, R. L.; Easley, J. F.; Peacock, F. M.
Mature grade Brahman cows grazing pangolagrass (Digitaria decumbens Stent.) from 3 to 17 years as the only source of nutrients other than common salt and red salt had an average of 2624 mcg vitamin A and 59 mcg B-carotene per gram dry liver and 46 mcg vitamin A and 1020 mcg B-carotene per 100 ml blood plasma. The liver of a 1168 pound cow had the equivalent of 16.3 million I. U. vitamin A. The cows had livers with approximately 28 times more vitamin A, and plasma 5.5 times more B-carotene than steers fed a finishing ration containing 10% yellow corn meal and 5% alfalfa meal for 140 days. Beef cows grazing well managed Florida improved pasture would obtain more than sufficient vitamin A for maintenance, reproduction, and milk production as indicated by their performance and storage of this vitamin.

Kruse, W. H.
Germination of broom snakeweed seed was found best at 60-70 F temperatures and was inversely related to moisture stress.
