饲粮中添加卷丹百合珠芽对藏猪生长性能、血清生化指标及肉品质的影响OA

The experiment aimed to investigate the effects of Lilium lancifolium bulbils on the growth performance,serum biochemical indices,and meat quality of Tibetan pigs.A total of 36 healthy Tibetan pigs with an average body weight of(17.51±0.65)kg were randomly divided into three groups,with six replicates per group,and two pigs per replicate.The control group(group CK)was fed a basal diet,while the groups TO and TT were fed diets supplemented with 1%and 2%Lilium lancifolium bulbils,respectively.The pre-test period was seven days,and the formal test period was 42 days.The results showed that compared with the group CK,the final body weight and average daily gain in the group TO were significantly increased(P<0.05),the apparent digestibility of crude fat in groups TO and TT was significantly increased(P<0.05),and the apparent digestibility of acid detergent fiber in the group TO was significantly increased(P<0.05).The dressing percentage in the groups TO and TT was significantly increased(P<0.05).The study shows that dietary supplementation with Lilium lancifolium bulbils can improve growth performance and slaughter performance,and enhance nutrient apparent digestibility in Tibetan pigs,with the optimal supplementation level being 1%.
