在这篇论文中，调查的结果，测试未来的种猪在群舍，与个人的采食量记录。将讨论的主题是：舍饲制度对采食方式和生产性能的影响，采食方式和生产性能之间的关系，以及采食方式的遗传方面。舍饲制度显著影响采食方式、饲料消化率、生长速度和饲料转化率。通过对活动水平和消化率的影响，进食频率和每日进食时间与生产效率呈负相关。采食量和采食率与生长速度和背膘厚呈显著正相关。采食量性状具有中等遗传力。
In this thesis investigations were directed at the consequences of testing future breeding pigs in group housing, with individual feed intake recording. Subjects to be addressed were: the effect of housing system on feed intake pattern and performance, relationships between feed intake pattern and performance and genetic aspects of the feed intake pattern. Housing system significantly influenced feed intake pattern, digestibility of feed, growth rate and feed conversion. Through effects on level of activity and digestibility, frequency of eating and daily eating time were negatively related with efficiency of production. Meal size and rate of feed intake were positively related with growth rate and backfat thickness. Feed intake traits had moderate heritabilities.
