One bogey with the age of premature
Under normal circumstances, the cow can only be established when it reaches 18 months of age and weighs 350 kg or more. However, at present, many cattle farmers are eager to produce milk from dairy cows. They often start breeding at around 12 months of age, which hinders the development of the bovine body. The result is that the speed is not satisfactory.
Two bogey predatory milking
Main performance: Dairy cows have a long lactation period, and low-yield cows have too many milkings on a daily basis. Under normal circumstances, the lactation period of dairy cows is 305 days, and the middle and high-producing dairy cows are milked 3 times a day. Some cattle farmers have shortened the dry period due to a delay in the breeding period or due to the high yield of dairy cows, making the lactation period too long; still insisting on squeezing three times a day for low-yielding dairy cows, resulting in excessive consumption of dairy cows' constitution and affecting the birth of the next baby. And lactation.
Three avoid feed single, do not pay attention to feed
There should be no less than two types of roughage for dairy cows and no less than three types of concentrated feed. At present, many cattle feedstuffs are mainly corn stalks, and concentrate feeds are mainly corn and cakes, and they have insufficient knowledge of silage.
Four bogey only pay attention to lactation
The management of dairy cows includes the management of calves, bred cattle, dairy cows (dry cows, lactating cows). Now many cattle farmers only pay attention to the feeding and management of dairy cows, resulting in a decline in milk production during the next lactation period.
Five Bogey Overlook Cows' Movement and Training
Some cattle farmers have long-term support for their dairy cows and they do not have grazing or set up sports grounds. Do not brush and tune the cows and ignore the breast massage for lactating cows.
Six taboos and abuse of drugs
Some cattle-raising households do not pay attention to disease prevention, lack the awareness of environmental disinfection and epidemic prevention, and once the disease occurs, cows will use drugs indiscriminately, leaving hidden risks for production.
Seven bogey cows postpartum breeding delay
Under normal circumstances, the cows begin to ovulate 13 to 15 days after delivery. The estrus is estrus, then there is a second estrus after 21 days, ie 30 to 35 days after childbirth. In response to this situation, try to change the habit of mating in the past two months.
High Precision Distance Sensor
Laser range sensors combine the advantages of a visible red sensing beam with the increased range of a laser. The optical distance sensor devices are Class 2 lasers, support Class 1 customized. The high precision autonics distance sensor is successfully be used to connect to Arduino, Raspberry Pi, with +-1mm to 3mm high accuray, and long-range solutions (max up to 150m) for your application.
