Abstract

Background: 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.

Results: Supplementation with IQ improved feed conversion ratio, while feed intake and daily gain were maintained.

Conclusion: 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.

添加异喹啉生物碱对商品生长肥育猪生产性能的统计过程控制分析。

背景: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，以评估生产参数随特定策略的实施而随时间的演变。本试验旨在采用SPC法评价生长育肥猪饲粮中添加异喹啉生物碱(IQ)对生长性能参数的影响。IQ是一种天然的植物次生代谢物，由于其在支持生长性能和整体健康状况方面的功效，在食用动物中得到了广泛的研究。试验收集了1,283,880头生长肥育猪的生产性能参数和用药情况，其中147,727头猪从出生第70天至屠宰期间添加了相同的基础饲粮。结果:添加IQ提高了饲料系数，维持了采食量和日增重。结论:SPC方法是在商业水平上评价猪饲料中添加新饲料添加剂对猪生长性能影响的有效统计工具。此外，添加IQ可提高生长肥育猪的生长性能，可作为降低饲料转化率的良好策略。
