The spectrophotometric method for pyrantel tartrate in swine feeds was collaboratively studied. Twenty-seven laboratories assayed feeds containing 0.0103, 0.0965, and 0.7902% pyrantel tartrate. Repeatability (sigmao) and reproducibility (sigmax) standard deviations were: sigmao = 0.00068%, sigmax = 0.00105% (10% of grand mean) for 0.0103% pyrantel tartrate level; sigmao - 0.0065%, sigmax = 0.0090% (10% of grand mean) for 0.0965% pyrantel tartrate level; and sigmao = 0.0415%, sigmax = 0.0743% (10% of grand mean) for 0.7902% pyrantel tartrate level. The mean theoretical recovery values for feeds containing 0.0103, 0.0965, and 0.7902% were 100, 97, and 96%, respectively. The method was adopted as official first action for feeds or concentrates containing 0.0106-0.8811% pyrantel tartrate.
对猪饲料中吡喹酮酒石酸盐的分光光度法进行了协同研究。27个实验室对含有0.0103%、0.0965%和0.7902%吡喹酮酒石酸盐的饲料进行了分析。重复性（sigmao）和再现性（sigmax）标准偏差分别为：对于0.0103%吡喹酮酒石酸盐水平，sigmao = 0.00068%，sigmax = 0.00105%（总平均值的10%）；对于0.0965%吡喹酮酒石酸盐水平，sigmao = 0.0065%，sigmax = 0.0090%（总平均值的10%）；对于0.7902%吡喹酮酒石酸盐水平，sigmao = 0.0415%，sigmax = 0.0743%（总平均值的10%）。含有0.0103%、0.0965%和0.7902%的饲料的平均理论回收率分别为100%、97%和96%。该方法被采纳为含有0.0106 - 0.8811%吡喹酮酒石酸盐的饲料或浓缩物的官方首次行动方法。
