Rock salt can control deer bite hair.

The bite problem of deer, also known as hair eating disease, is a chronic metabolic disease caused by abnormal taste due to the dysfunction of digestive tract and nervous system. The main causes are late winter and early spring, long-term feeding by rain, sun-dried hay or improper feeding and management, incomplete nutrition, excessive deer density and so on. The incidence is sometimes as high as 100%.

At the beginning of the disease, only a few deer bite, and then most deer bite each other, and some will bite off the hair and swallow it in a mass after a little chew. with the peristalsis of the stomach can be rolled into a ball or mixed with plant fibers in the stomach to gradually form hair balls, stay in the rumen. If the hair ball gets stuck in the true stomach or intestines, it will cause loss of appetite, malnutrition, and even lead to weakness and hypoplasia of individual deer. Such young deer often die in about 7 days, resulting in serious economic losses.

Rock salt, also known as stone salt, exists in solid form in nature, which mainly contains Ca, C1, Na, K, Fe, Gu, Zn, S10 kinds of mineral elements. Among animals, ruminants such as cattle, sheep and deer like to lick. * * since October 1994, in addition to measures such as reasonable matching of feed, strengthening management, expanding the enclosure and reducing herd density, the Alar Deer Farm has also set up a salt trough in the deer circle and placed large chunks of solid rock salt (3-4 kg / block) to allow the deer to lick according to their needs. the perennial morbidity has been reduced by 97%, the appetite has increased significantly, and the fat condition is much better than in previous years, except for individual deer bite problems, timely isolation, no impact on production. The bite problem has been effectively controlled within 3 years, and the breeding rate has been greatly improved.
