Description

A medicinal bath and identification method for sheep in large-scale sheep farms

Technical field

The invention relates to the technical field of animal husbandry, and specifically relates to a medicinal bath and identification method for sheep in a large-scale sheep farm.

Background technique

Sheep is the collective name of the subfamily Ovis, class Mammalia, order Artiodactyla, Bovidae, subfamily Ovis, and is one of the domestic animals of humans. Hairy, four-legged ruminants that are the main source of wool. Our country mainly raises goats and sheep. Sheep are particularly susceptible to ectoparasitic diseases due to their biological characteristics and living habits. The most common external parasitic diseases in sheep are scabies, fleas, lice, etc., which are highly contagious and harmful to the sheep, seriously affecting the health of the sheep and their production performance such as wool and meat production.

In order to ensure the health of the sheep on the farm and effectively improve the economic benefits of the sheep industry, medicated bathing is the most effective way to prevent and treat sheep ectoparasites in large-scale sheep farms.

The traditional method of sheep medicated bath is a water tank medicated bath. The sheep are put into the water tank and soaked and rinsed with the prepared medicated bath. Since it can only be operated by a single sheep and requires at least two people to complete, it is time-consuming and expensive. Artificially; with the rise of large-scale sheep farms, water tank medicated baths can no longer meet the needs of sheep farms.

At present, most sheep farms use trough-type medicated baths, that is, they build a trough-shaped medicated bath, prepare the medicated bath liquid, and drive the sheep in from one end during the medicated bath and walk along the trough to the other end. This process Complete the medicinal bath. In actual use, this trough-type medicated bath has the disadvantages of large floor space and complex operation. The lamb cannot follow the big sheep in the medicated bath. The head and neck of the sheep cannot be effectively medicated bathed. The sheep have a large stress response. It is easy to get squeezed and drowned while walking in the trough. Each medicinal bath requires the preparation of the entire medicated bath solution. The effect of the medicated bath is reduced for sheep entering later, and the medicated bath solution cannot be recycled and reused.
