520 $a Radio frequency (RF) technology is used in electronic monitoring and data acquisition devices currently available to the commercial animal feeding industry for continuously monitoring the feeding and watering behaviors of feedlot animals.
520 $a There is therefore the need for statistical process control (SPC) procedures that can be used on-line, in conjunction with these electronic data collection systems, to achieve a cost effective system that can quickly detect animal morbidity.
520 $a In this dissertation, a modified cumulative sum (modified CUSUM) procedure is proposed based on modifying the traditional CUSUM scheme for count data. Additional CUSUM design parameters and additional out-of-control conditions are introduced to give the procedure several enhanced features, improve its detection capability, and reduce the average run length (ARL).
520 $a The method is evaluated using simulated Poisson data, and recommendations for the choice of the extra design parameters are discussed. An outline is provided to show how the modified procedure can be implemented for a generic cattle feedlot data, which can be acquired from a digital monitoring and data collection system based on radio frequency (RF) ear-tag technology.
520 $a Results demonstrate that the modified CUSUM scheme can indeed achieve higher sensitivity and performance than the traditional CUSUM scheme. The proposed modified CUSUM schemes can also be designed to be relatively robust to isolated outliers that may be present in the data. It is further demonstrated that an optimal design of this modified CUSUM scheme can indeed be very useful in the early detection of morbidity among group-fed animals.
