【摘要】：研究旨在观察大豆磷脂油对保育猪浓缩饲料中油脂氧化相关指标的影响。选用添加了大豆油4%的浓缩饲料配方,以等量大豆磷脂油替代0、50%、100%的大豆油生产浓缩饲料(简称C组、T1组与T2组),每组随机抽取12包浓缩饲料,每包25 kg,分为4个重复,每个重复3包浓缩饲料。在12周的试验期内每周一次测定粗脂肪的酸价、过氧化值及丙二醛值。结果表明:(1)酸价:在2~12周,T1组与T2组显著低于C组(P0.05),在4~9周,T2组显著低于T1组(P0.05);(2)过氧化值:在1~12周,T1组与T2组显著低于C组(P0.05),第2周及7~12周,T2组显著低于T1组(P0.05);(3)丙二醛值:在4~12周,T1组与T2组显著低于C组(P0.05),同时,T1组与T2组差异不显著(P0.05)。结果提示大豆磷脂油在浓缩饲料中50%或100%替代大豆油,可以延缓饲料中油脂的酸价、过氧化值及丙二醛值的变化,具有显著的抗氧化效果。
[Abstract]:The aim of this study was to observe the effect of soybean phospholipid oil on the indexes of lipid oxidation in pig concentrate feed.The concentrated feed formula with 4% soybean oil was used to produce concentrated feed with the same amount of soybean phospholipid oil instead of 100% soybean oil (group C, group C, group T 1 and group T 2, respectively). 12 packets of concentrated feed were randomly selected from each group, each package of 25 kg, divided into 4 replicates.Each repeat 3 packets of concentrate feed.The acid value, peroxide value and malondialdehyde value of crude fat were determined once a week during the 12 week trial period.The results showed that the acid value in T1 and T2 groups was significantly lower than that in C group at 2w / 12 weeks, and that in T2 group was significantly lower than that in T1 group (P 0.05 P0.05) at 4 ~ (9) weeks); at 1T _ (12 weeks), T _ 1 group and T _ 2 group were significantly lower than C group (P 0.05), and at the 2nd week and 712th week, T _ 2 group was significantly lower than that of T _ 1 group (P 0.05).Malondialdehyde (MDA) value was significantly lower in T1 and T2 groups than that in C group (P 0.05), but there was no significant difference between T 1 group and T 2 group (P 0.05).The results suggested that 50% or 100% soybean phospholipid oil could delay the changes of acid value, peroxide value and malondialdehyde value of the fat in the concentrate feed, and had obvious antioxidant effect.
