Comprehensive determination method of beef cattle feed efficiency based on feeding behavior and growth index

Abstract

The application discloses a beef cattle feed efficiency comprehensive determination method based on feeding behavior and growth indexes, and belongs to the field of beef cattle feeding and livestock technology. The method comprises the following steps: collecting individual cattle daily multi-source data packets; inputting video data into a visual recognition model to output a daily feeding behavior parameter set; calculating average daily weight gain and feed conversion rate, and standardizing the daily feeding behavior parameter set, average daily weight gain and feed conversion rate to obtain a daily standardized parameter set; constructing a feeding behavior health index and a traditional feed efficiency benchmark value based on the daily standardized parameter set; calculating a comprehensive feed efficiency value based on the feeding behavior health index and the traditional feed efficiency benchmark value; and performing beef cattle feed efficiency comprehensive determination based on the comprehensive feed efficiency value. The application realizes multi-source data fusion of feeding behavior and growth indexes, and achieves early precise early warning and individualized management of feed efficiency through high-precision model recognition and comprehensive evaluation.
