富硒五谷虫粉对生长育肥猪生长性能、 血清生化指标、屠宰性能和肉品质的影响

The experiment investigated the effects of seleiiium-enriched mealworm powder on the growth performance, serum biochemical indices, carcass performance, and meat quality in growing-finishing pigs. A total of 72 healthy pigs (Duroc x Landrace x Yorkshire), weighing about 21 kg, were randomly divided into three groups, with six replicates in each group and four pigs per replicate. The control group was fed with a basal diet, and the 0.1% group and 0.2% group were supplemented with 1 kg/t and 2 kg/t of selenium-enrich mealworm powder in the basal feed, respectively. The experiment lasted for 17 weeks. The results showed that compared with the control group, 0.1% selenium-enriched mealworm powder to the diet could significantly increase the average daily gain of growing-finishing pigs (P<0.05). 0.2% selenium-enriched mealworm powder could significantly increase serum immunoglobulin A (IgA) content, glutathione peroxidase (GSH-Px), and superoxide dismutase (SOD) activities (jB<0.05), while significantly decreasing serum malondialdehyde (MDA) content in pigs (P<0.05). 0.1% and 0.2% selenium-enriched mealworm powder could increase the concentrations of intramuscular fat, selenium, linoleic acid, a -linoleic acid, arachidic acid, eicosenoic acid, and eicosadienoic acid in the longissimus dorsi muscle of pigs (2k0.05). The results show that dietary supplementation with selenium-enriched mealworm powder can improve growth performance, immunity, antioxidant ability, and the nutritional value of meat in growing-finishing pigs.
