This study aimed at investigating the effects of oat silage and sex on the growth performance, behaviour and antioxidants accretion in perirenal adipose tissue of organic pigs. In total, ninety-three crossbred pigs (51.8 ± 7.6 kg) from two sexes (entire males vs. females) were assigned to two dietary roughage supplement treatments (control with straw vs. 200 g dry matter/pig/day of oat silage supplement) in a 2 × 2 factorial design until 120 kg of live-weight. There was no significant effect of forage type or sex on growth performance. However, the oat silage had a positive effect on the exploration behaviour on the outdoor run fixtures. The retinol concentration in adipose tissue was higher in the pigs that were given the oat silage than in those receiving the control diet, but the feeding treatment did not affect the concentration of α-, γ- and δ- tocopherols. The oat silage carried out lower cholesterol accretion in adipose tissue than the control diet. The sex did not affect retinol, tocopherols or cholesterol concentration in adipose tissue. Dietary silage supplement may be used by producers to enhance pork vitamin A content.

这项研究旨在调查燕麦青贮饲料和性别对有机猪肾周脂肪组织的生长性能，行为和抗氧化剂增生的影响。总共将来自两种性别（整个雄性对雌性）的九十三头杂种猪（51.8±7.6千克）分配到两种饮食粗饲料补充处理中（用稻草对比。以2×2因子设计设计200克干物质/猪/天的燕麦青贮饲料，直到120千克活重。饲草类型或性别对生长性能没有显着影响。然而，燕麦青贮饲料对户外跑步装置的探索行为具有积极影响。饲喂燕麦青贮饲料的猪脂肪组织中的视黄醇浓度高于接受对照饮食的猪，但是饲喂处理不会影响α-，γ-和δ-生育酚的浓度。燕麦青贮饲料在脂肪组织中的胆固醇含量比对照饮食低。性别不影响脂肪组织中的视黄醇，生育酚或胆固醇浓度。生产者可以使用饲料中的青贮饲料来提高猪肉中维生素A的含量。
