As the utilization of manual semen injection makes progress in present day dairy cultivates the significance of exact hotness location turns out to be more basic for ranch productivity.
Conventional hotness identification techniques depended on visual perception of hotness related conduct showed by the cows using an AM-PM seeing timetable – the cows are noticed for a half hour two times per day, once toward the beginning of the day and once in the evening. Normal precision of visual perception is around 40% because of the way that visual hotness recognition requires skill, short warms are common and may fall between perceptions, the vast majority of warms happen among 12 PM and 6am when there is nobody to see them among different reasons. Clearly this degree of exactness passes on a great deal to be wanted.
The shortcoming of visual perception prompted the osmosis of a few kinds of answers for the issue of hotness location. These hotness location helps can for the most part be isolated into three classifications: mounting sensors which give a sign of the cow in heat getting mounted by another cow, chemical synchronization conventions which time the cows’ hotness cycles and electronic hotness identification helps.
Tail painting and mount sensors give a sign to the rancher assuming the cow has been mounted by different cows (a normal hotness related conduct) and hence is in heat. These techniques don’t 跌倒警報器 give a stamped improvement in heat discovery exactness as they are impacted by cow exercises disconnected to warm, nor are they ready to decide the specific planning of the start of the hotness cycle to enhance insemination timing and require an impressive interest in labor to direct, keep up with and screen them.
One more well known strategy expected to build heat location is the organization of chemical synchronization conventions to synchronize the circumstance of warms across the crowd. The cows are exposed to a chemical shots which initiate every one of the infused cows into heat at a particular time at which they will be inseminated. While they might tackle the issue of knowing when a hotness happens, these conventions cause significant costs in labor and in buying chemicals. To date no examination was led regarding the impact of the chemicals on the cows and the milk burning-through open. It is profoundly likely that a negative public response would rise assuming the degree of the utilization of synchronization projects would be pitched.
Electronic hotness identification helps were first brought into the market in the 1980’s with the arrangement of pedometers. Pedometers are lashed to the cow’s leg and count the quantity of steps she takes – an increment in the quantity of steps taken by the cow gives a 70%-80% precise sign of the cow being in heat.
