The barn is to face south to the south and adopts swept-in mangers and neck clips. The cowshed is divided into single row and double row. The double column is divided into double row head pair and double row tail pair. Units must have a single barn for dairy cows under 30 heads, and the establishment of a milking station should not use a double-tailed barn. The stadium should be leveled with bricks. Do not use cement to wipe the surface. It is best to lay a 20-cm-thick sand with a low height in the middle to facilitate drainage. The fence column is 3 meters apart and the bar is fixed with 3 steel bars or steel wire.
The silo can be planned centrally or separately. The width should not be too large. Calculate 10 cows with 1 meter. Generally, the maximum width should not exceed 10 meters. Silage should be calculated based on 15 cubic meters per head. The establishment of a dedicated cow path will allow dairy cows and breeders to follow their own path, separate the sewage from the clean roads, and reduce the pollution of the cow's excrement to the park's environment. The cow's road is about 1.5 to 2.0 meters wide.
The park entrance is equipped with a disinfection pool and a disinfection room; a technical service station is set up in the park as a workplace for veterinary and artificial insemination; each dairy farm must establish an institutional milking station, and select the model according to the number of cows in the park. Each household builds a 20 cubic meter digester.
Dairy cattle parks should be of moderate size, not too large. It is more appropriate to have 400 to 600 high-yielding dairy cows in one park, and more than 1,000 parks can be divided into 2 community buildings.
IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range with high frequency up to 100hz. It's great for Unmanned Aerial Systems. If you need us send you data sheet and spec for this products, offering sample as well, pls tell us, thank you.
