奶牛采食量检测仪的设计与技术研究

Design and study of the test instrument for feed intake of the dairy cow

为了及时、准确地测量出奶牛的采食量,本文根据奶牛在采食、反刍和吞咽时的行为表现,本文提出了通过传感器实时检测奶牛颞窝部位的运动规律来反映牛只采食量大小的原理,并根据此原理研制了一种基于单片机控制和检测的奶牛采食量自动检测仪。该检测仪能够准确地测量并计算出奶牛的吞咽次数,然后根据奶牛吞咽时食团质量的大小计算出奶牛的采食量,并且可将一定时期内的采食量进行回归分析制定出相应的营养方案。本检测仪实现了快速、方便和精确的采食量测定目的。

In order to timely and exactly measure the feed intake of the dairy cow, a measurement principle was developed that is based on testing the temporal socket movement of the cow when it is ruminating or taking food, and the frequency and period of the movement can be used to indicate the feed intake of the cow. A test instrument with a sensor measuring the temporal socket movement was designed and manufactured, which is based on microcontroller controlling and detecting technique. The number of swallows of the cow is tested and calculated accurately, from which the feed intake is calculated easily based on the mass of the feed for each swallow. The feed intake in a time period can be analyzed, and the nutrition plan for the cow is made according to the results. The proposed instrument reaches the purpose of testing the feed intake of the dairy cow rapidly, accurately and conveniently.
