Design And Research Of Testing Instrument For Cow's Feed Intake

Feeding intake of the cow was defined as the quantity of the forage grass of the cow in the unit time. The growth and the output of creamery of the cow would be affected by feed intake. In order to make sure the growth and the ideal output of creamery of the cow, feed intake of the cow should be kept highly. The accurate determination and calculation was thought as the base which made the good nutrition scheme of the cow. But by far the precision of cow's feed intake detecting has not been enhanced, and the behavior of cow when they are feeding would be infected by most of the detected method, so feed intake would be infected too. At present the object of most of the detected method was a group of cow, there was not ideal method to detect the individual cow's feed intake. It would be very important for stockbreeding if there was a specific method to detect the individual cow's feed intake.The behavior when cow was ruminating, chewing or swallowing was analyzed while the characteristic of cow's living and physiological was realized. The technology of sensor, real-time detecting, microcontroller and advanced language design was adopted to design the instrument system. Based on theories of One-chip Processor Control Theories, Analogue and Digital Electronic, Theoretic Mechanics and Machine Design, Advanced Language Design, attained the course has to cross and blends. The main research about this task included four parts as follows.The character of cow when they were feeding was investigated. Movement of the cow's temporal socket would be appeared when the cow was ruminating, chewing or swallowing. The movement would differ along with the different feeding behavior. The amount of cow's feed intake would be reflected through the number of cow's swallow.In order to timely and exactly make sure the feed intake of the cow, the principle of measuring is developed in this paper. Because when a cow is ruminating or taking food the temporal socket movement of it occurs orderly, the frequency and the period of the movement could show the feed intake.
