Bulletin No. 372 - The Nutritive Value Of Winter Range Plants In The Great Basin As Determined With Digestion Trials With Sheep, C. W. Cook, L. A. Stoddart, L. E. Harris

UAES Bulletins

During the winter grazing seasons from 1946 to 1953, studies were carried on throughout the desert ranges of western Utah to determine nutritive content and digestibility of range forage plants.

These desert areas receive about 7 inches of precipitation annually and the vegetation consists, chiefly, of saltbush and sagebrush types.

The average floral composition of the desert areas studied was about 74 percent browse, 25 percent grass, and 1 percent forbs. However, on some areas there was more grass than browse and, on still others, large quantities of forbs were present, primarily Russian-thistle.

Digestion trials were carried out under normal …

Bulletin No. 342 - The Nutritive Content Of The Grazing Sheep's Diet On Summer And Winter Ranges Of Utah, C. Wayne Cook, Lorin E. Harris

UAES Bulletins

Approximately two million sheep graze the native ranges of Utah each year. These animals are on the range most of the year and their food supply must come from range plants as they are normally selected. The nutritive value of range forage is often borderline or deficient in essential nutrients, yet, sufficiently adequate to prevent obvious physiological disorders. These mild deficiencies may affect the productive efficiency of the animal even though no symptoms are apparent.

Bulletin No. 307 - Skin Folds In Sheep, Milton A. Madsen, Alma C. Esplin, Ralph W. Phillips

UAES Bulletins

Sheep vary greatly, even within breeds, in the number and size of folds in the skin. At one time producers were emphasizing the importance of having a large number of skin folds in fine wool sheep such as the Merino and Rambouillet. This was based on the belief that skin folds were associated with high yields of grease wool and fineness of wool fibers. In recent years the trend has been toward a smoother bodied sheep with longer staple and less grease in the fleece.

The objects of this bulletin are to present a review of the available information concerning …

Bulletin No. 101 - Feeding Experiments With Cattle, Sheep, Swine And Horses, R. W. Clark

UAES Bulletins

Since the establishment of sugar factories in this State, considerable inquiry has arisen regarding the food value of sugar beets and the by-products of the factories. The last publication from this station on the subject was Bulletin No. 90 which gave the results of feeding sugar beet pulp and molasses in various combinations to sheep and steers. Previous to the appearing of this publication some experimental work had been carried out in feeding sugar beets to swine and sugar beet pulp and beet molasses to sheep. The results secured seemed to warrant further work in the same direction and in …
