对4个品种(大白猪、长白猪、杜洛克猪和皮特兰猪)各116头和89头的205头生长公猪的饲养策略进行了研究。猪以12-14头为一组，每组一个品种。用计算机化的饲料摄入量记录系统记录饲喂模式。对每头猪实行单独用餐标准，将小组访问划分为不同的用餐。在整个研究过程中，每10天称一次猪的体重，以计算平均日增重。对于这四个品种，每天进餐或来访的次数与进餐或来访的数量呈负相关(-0.88
Feeding strategy was studied in 205 growing boars in two blocks of 116 and 89 pigs of four breeds (Large White, Landrace, Duroc and Pietrain) respectively. Pigs were housed in groups of 12-14 individuals, with a single breed in each group. Feeding patterns were recorded with a computerized feed intake recording system. An individual meal criterion was applied to each pig to group visits into meals. Pigs were weighed every 10 days throughout the study to calculate average daily gain. For the four breeds, the number of meals or visits per day was negatively correlated with sizes of meals or visits (-0.88
