在为期34天的实验中使用了三批断奶仔猪（总共n = 310头猪），以验证IVOG（R）饲喂站作为监测群养断奶仔猪个体采食量的工具的使用。IVOG（R）断奶仔猪饲喂站包括一个放置在称重传感器上的单空间干式饲喂器，并结合电子识别。使用IVOG（R）饲养站饲养的192头断奶仔猪（18个围栏）的数据制定IVOG（R）数据筛选方案。为了评估IVOG（R）数据的质量，将根据筛选的IVOG（R）数据计算的每栏摄食量与根据饲料称重计算的摄食量进行比较。为了评估在实际养猪条件下使用IVOG（R）饲喂站的适用性，将96头由IVOG（R）饲喂站饲喂的断奶仔猪的性能与118头使用商业单空间干式饲喂器（11个围栏）饲喂的断奶仔猪的性能进行了比较。对于所有试验期，根据IVOG（R）数据计算的每栏摄食量与根据饲料称重计算的摄食量（平均回收率101.1%）相似（p > 0.1）。此外，饲料回收率没有不同的饲养站（p > 0.1）。断奶后13天内，单隔式干饲器饲养的仔猪平均日采食量显著高于饲养站饲养的仔猪（p < 0.05）。平均日增重和增重饲料比在两种饲养系统之间没有差异（p > 0.1）。在剩余的21天中，在整个实验期间的平均值，性能在饲养系统之间没有差异（p > 0.1）。可以得出结论，断奶仔猪IVOG（R）饲喂站是监测群养断奶仔猪个体采食量的合适工具。
Three batches of weanling pigs (total n = 310 pigs) were used in a 34-day experiment to validate the use of an IVOG(R) feeding station as a tool for monitoring individual feed intake of group-housed weanling pigs. An IVOG(R) feeding station for weanling pigs consists of a single-space dry feeder placed on a load cell in combination with electronic identification. Data of 192 weanling pigs (18 pens) fed by IVOG(R) feeding stations were used to develop a protocol for the screening of IVOG(R) data. To assess the quality of the IVOG(R) data, the feed intake per pen computed from the screened IVOG(R) data was compared with the feed intake calculated from feed weighing. To assess the suitability of the use of IVOG(R) feeding stations under practical pig husbandry conditions, performance of 96 weanling pigs fed by the IVOG(R) feeding stations was compared with that of 118 weanling pigs that were fed using commercial single-space dry feeders (11 pens). Feed intake per pen computed from the IVOG(R) data was similar to the feed intake calculated from feed weighing (average recovery 101.1%) for all test periods (p > 0.1). Furthermore, feed recovery did not differ among feeding stations (p > 0.1). During the first 13 days after weaning, the average daily feed intake (ADFI) of weanling pigs fed by the single-space dry feeders was higher (p < 0.05) than that of weanling pigs fed by the feeding stations. Average daily gain and gain to feed ratios did not differ (p > 0.1) between both feeding systems. During the remaining 21 days and averaged over the entire experimental period, performance did not differ between the feeding systems (p > 0.1). It can be concluded that IVOG(R) feeding stations for weanling pigs are a suitable tool to monitor individual feed intake of group-housed weanling pigs.
