Statistical Process Control (SPC) is a powerful statistical tool that can be used in animal production to evaluate the evolution of production parameters overtime in response to the implementation of a specific strategy. The aim of this study was to evaluate the effect of supplementing growing-finishing pigs with isoquinoline alkaloids (IQ) on growth performance parameters by using the SPC method. IQ are natural secondary plant metabolites which have been extensively investigated in food animals due to their efficacy in supporting growth performance and the overall health status. Performance parameters and medication usage were collected from 1,283,880 growing-finishing pigs fed the same basal diet, 147,727 of which were supplemented with IQ from day 70 of life until slaughter.
Supplementation with IQ improved feed conversion ratio, while feed intake and daily gain were maintained.
SPC methods are useful statistical tools to evaluate the effect of using a new feed additive in the feed of pigs on growth performance at a commercial level. Additionally, IQ supplementation improved growth performance and it can be considered as a good strategy to reduce feed conversion in growing-finishing pigs.
统计过程控制（SPC）是一种强大的统计工具，可用于动物生产中，以评估生产参数随时间的变化情况，以响应特定策略的实施。本研究的目的是通过使用SPC方法评估在生长育肥猪日粮中添加异喹啉生物碱（IQ）对生长性能参数的影响。IQ是天然的植物次生代谢产物，由于其在支持生长性能和整体健康状况方面的功效，已在食用动物中得到广泛研究。从1,283,880头饲喂相同基础日粮的生长育肥猪中收集性能参数和药物使用情况，其中147,727头从出生第70天开始直至屠宰一直添加IQ。
添加IQ可提高饲料转化率，同时维持采食量和日增重。
SPC方法是评估在猪饲料中使用新饲料添加剂对商业水平生长性能影响的有用统计工具。此外，添加IQ可提高生长性能，可被视为降低生长育肥猪饲料转化率的良好策略。
