Abstract：
Nowadays, the global animal industry faces considerable challenges in securing sufficient feed resources. Responding to consumer demands for reduced use of antibiotics in animal nutrition, better animal welfare status, and reduced impact on the environment, there is an increased urgency to develop innovative functional feeds with a reduced environmental footprint and the ability to improve meat quality and safety. In an effort to explore innovative feed ingredients for growing pig diets, the combined dietary supplementation of Tenebrio molitor larvae and chitosan was investigated. An experimental trial was performed with 48 weaned pigs (34 days of life; mixed sex) that were randomly assigned to four treatment groups (with six males and six females each): Group A (control), Group B (supplemented with T. molitor larvae at 10%), Group C (supplemented with chitosan at 0.05%), and Group D (supplemented with both ingredients at 10% and 0.05%, respectively). On the 42nd day of the experimental trial, samples of blood, feces, and carcass parts were taken for analysis. The results indicated that the insect larvae meal significantly improved (p < 0.05) overall performance, increased (p < 0.05) blood red blood cell content, increased meat phenolic content (p < 0.05), improved meat oxidative stability (p < 0.05), and affected meat fatty acid profile (p < 0.05). On the other hand, chitosan had no significant effect on overall performance (p > 0.05), but it significantly increased blood lymphocyte content (p < 0.05), affected the fecal microbiota (p < 0.05), improved meat oxidative stability (p < 0.05), increased meat phenolic content (p < 0.05), and affected meat fatty acid composition (p < 0.05) and (p < 0.05) meat color. Finally, the combined use of both T. molitor and chitosan significantly affected some important zootechnical parameters (p < 0.05), fecal microbial populations (p < 0.05), meat color (p < 0.05), and fatty acid profile (p < 0.05). Further investigation into the potential interaction between insect larvae meals and chitosan in pig diets is advised.
摘要：
如今,全球畜牧业在确保充足的饲料资源方面面临相当大的挑战。响应消费者对减少动物营养中抗生素使用的需求，更好的动物福利状况，减少对环境的影响，越来越迫切需要开发具有减少环境足迹和提高肉类质量和安全性的创新功能饲料。为了探索用于种植猪饮食的创新饲料原料，研究了黄粉虫幼虫和壳聚糖的联合日粮补充。对48只断奶猪（生命34天；混合性别）进行了一项实验试验，将其随机分配到四个治疗组（每组6只雄性和6只雌性）：A组（对照），B组（补充了10％的黑虫幼虫），C组（添加0.05％的壳聚糖），和D组(补充了10%和0.05%的两种成分，分别)。在实验试验的第42天,血液样本,粪便,和car体部分进行分析。结果表明，昆虫幼虫粉显著提高(p<0.05)总体性能，血红细胞含量增加(p<0.05)，增加肉类酚类含量(p<0.05)，改善肉的氧化稳定性（p<0.05），并影响肉类脂肪酸谱(p<0.05)。另一方面,壳聚糖对整体性能无显著影响(p>0.05),但它显着增加血液淋巴细胞含量（p<0.05），影响粪便微生物群(p<0.05)，改善肉的氧化稳定性（p<0.05），增加肉类酚类含量(p<0.05)，并影响肉的脂肪酸组成（p<0.05）和（p<0.05）肉的颜色。最后,墨虫和壳聚糖的联合使用显着影响了一些重要的动物技术参数（p<0.05），粪便微生物种群(p<0.05)，肉色(p<0.05)，和脂肪酸谱(p<0.05)。建议进一步研究猪日粮中昆虫幼虫粉与壳聚糖之间的潜在相互作用。
