Abstract:

The fattening efficiency index (FSA) comprehensively took into account daily weight gain, feed conversion ratio, and feeding time, and could more accurately reflect the overall effect of feeding management. This study explored the application of FSA in evaluating the feeding management effect of fattening pigs, aimed to bring positive impacts to pig farming enterprises in terms of production management efficiency, economic benefits improvement, and overall industry development. All batch data of fattening pig farms from 2023 to 2024 were selected for statistical analysis. The results showed that: FSA had a strong correlation with daily weight gain, survival rate, and feed conversion ratio, and a negative correlation with costs such as medicine and vaccine costs, feed costs per unit weight gain, and fattening costs per unit weight gain; during the application of FSA, the survival rate (SVL) and average daily gain (ADG) of fattening pigs showed a quarterly upward trend, while the feed conversion ratio and cost indicators continued to decline. Through comprehensive analysis, it was recommended to set the goal of FSA assessment as FSA≥250.
