The current experiment was conducted to investigate the application effects of selenium conjugated to insect protein (SCIP) in the production of selenium-enriched eggs. A total of 450 laying hens were randomly assigned to five dietary groups, each group consisting of six replicates. Hens in the control group received a diet without selenium supplementation, whereas hens in the other four groups received diets supplemented with either 1, 2, 5, or 10 mg/kg of selenium from SCIP. The productive performance, egg quality, antioxidant and immune capacity, biochemical indices, intestinal morphology, and oviduct health of laying hens were evaluated. The results showed that the supplementation of organic selenium provided by SCIP in the diets of laying hens enhanced performance and egg quality without any toxicity effect, even at the 10 mg/kg inclusion level. A level of 2 mg/kg of selenium provided by SCIP in diets tentatively improved the serum antioxidant and immune capacity, intestinal development, and oviduct health of laying hens in a conspicuous manner. Hence, the biosafety and positive effects of SCIP as a feed additive supplement in laying hens' diet have been demonstrated with the enhanced production of safe and selenium-enriched eggs.
本试验旨在研究昆虫蛋白结合硒（SCIP）在富硒蛋生产中的应用效果。将450只蛋鸡随机分为5个日粮组，每组6个重复。对照组蛋鸡饲喂不添加硒的日粮，而其他4组蛋鸡分别饲喂添加1、2、5或10 mg/kg SCIP硒的日粮。对蛋鸡的生产性能、蛋品质、抗氧化和免疫能力、生化指标、肠道形态及输卵管健康状况进行了评估。结果表明，在蛋鸡日粮中添加SCIP提供的有机硒可提高生产性能和蛋品质，且无任何毒性作用，即使在添加水平为10 mg/kg时也是如此。日粮中添加2 mg/kg SCIP硒可显著改善蛋鸡的血清抗氧化和免疫能力、肠道发育及输卵管健康状况。因此，SCIP作为蛋鸡日粮中的饲料添加剂补充剂的生物安全性和积极作用已通过安全且富硒蛋的增产得到了证明。
