The composition of gorse (Ulex europaeus)

AbstractGorse (Ulex europaeus) has been shown to be a useful source of protein of good digestibility but to have a high fibre content. Although well provided with calcium and sodium, it proved to contain inadequate amounts of phosphorus and of the more important trace elements. The possible usefulness of the plant as a winter fodder is discussed.

The Use of Keratin Products in Poultry Rations

KERATIN proteins, in their natural state, are considered to be quite indigestible by animals and birds. However, there are reports that certain treatments applied to keratins, particularly fine grinding, may make them a useful source of protein in the diet.In a series of three papers, Wagner and Elvehjem (1942 Wagner and Elvehjem (1943) and Newell and Elvehjem (1947) showed that finely powdered swine hoofs were well utilized by chicks, particularly if heat was minimized during grinding. Hog hair and chicken feathers were less satisfactory.Wilder (1953) reported that processed feather meal was of value in chick starter, particularly so if it was combined with blood meal.On the other hand, Slinger et al. (1944) found that a product consisting of a finely ground mixture of cattle hoofs, swine hoofs and horn was of little value as a protein supplement for chicks.In the present paper feeding trials with four keratin products, processed …
