電子頸圈感測器效益之研究- 以嘉原畜牧場為例

Abstract

本研究透過個案分析，探討自動監測系統對於乳牛產業的效益。個案牧場於2018年導入電子頸圈感測器(Electronic Neck-Mounted Sensor, ENMS)，提供24小時牛隻發情和反芻等資料，協助牧場管理人員注意發情的牛隻，以掌握配種適期，提高配種效率，縮短牛群的產犢間距。 根據個案實際運用ENMS的數據，可以發現該系統不僅可以促進牧場各區牛群的管理效率及生乳品質，也可以利用紀錄牧場的工作狀況或是乳牛健康管控。個案已經累積兩年多的資料，確實有兩大效益的提升：一、小牛的頭數增加；二、牧場乳量的提昇。以財務管理角度如計算投資新設備的淨現值(Net Presnt Value, NPV) 為248,690.85元；內部報酬率(Internal rate of return)為11.38%。顯然導入電子頸圈感測器的經濟效益大於成本而值得投資。本研究建議政府協助酪農取得低利貸款以推廣導入電子自動化設備。

The traditional dairy farming industry in Taiwan mainly relies on manual feeding and monitoring of cattle health. This study explores the main benefits of automatic monitoring systems for the dairy industry. The case farm introduced the Electronic Neck-Mounted Sensor (ENMS) automation system in 2018 to provide cattle activies, estrus and rumination data detected in 24 hours as well as to assist the farm management to pay attention to the estrus cattle which the management can master the right time of breeding, improve the breeding efficiency, shorten the calving interval of cattle. According to the actual use of ENMS data in individual case, it can be found that system can not only promote the management efficiency of in various cattle groups and raw milk quality, but use the system to momitor on-going the status of the whole herd or the health control. The study case has accumulated more than two years of data that can be analyzed the specific benefits of the farm at the operational level, such as increasing the number of daily cows, milk production, etc.. Through the perspective of financial management, such as calculating the Net Present Value (NPV) and Internal rate of return (IRR) of investing in new equipment as a reference for the benefit evaluation of daily farmers and as a basis for the government to formulate counseling policies. The study proposes policy recommendations. First, encouraging dairy farmers to apply computerized feeding and health management to herds. Second, the government assists dairy farmers in obtaining low-interest bank loans to promote the introduction of electronic automation equipment.
