The research aimed to evaluate how effective hydrated sodium calcium aluminosilicates (HSCASs) and discarded date pits (DDPs) are as dietary adsorbents for aflatoxin B1 (AFB1) in enhancing the performance and health of broiler chickens aged 16 to 30 days. A total of 240 Ross 308 straight-run broilers were randomly allocated into four dietary groups, each with 10 replicates: a control diet, a control diet with 1000 ppb AFB1, an AFB1-contaminated diet with 0.5% HSCAS, and an AFB1-contaminated diet with 4% DDP. Incorporating HSCASs or DDPs into the AFB1-contaminated diet resulted in significant improvements across various parameters, involving increased body weight, improved feed conversion ratio, higher dressing percentage, decreased relative weights of kidney and spleen, elevated serum levels of total protein, globulin, and glucose, reduced serum alanine aminotransferase activity, and heightened hepatic protein concentration and glutathione peroxidase activity, along with diminished hepatic malondialdehyde content and glutamic oxaloacetic transaminase activity. Moreover, both supplements led to increased ileal villus height and surface area, enhanced apparent nitrogen-corrected metabolizable energy digestibility, and decreased AFB1 residues in the liver and kidney. Moreover, the dietary inclusion of DDPs significantly decreased relative liver weight, raised serum albumin concentration, lowered serum alkaline phosphatase activity, enhanced hepatic total antioxidant capacity level, and augmented ileal villus width. Conversely, the dietary addition of HSCASs significantly heightened apparent crude protein digestibility. In conclusion, the inclusion of HSCASs and DDPs in AFB1-contaminated diets can mitigate the toxic effects of AFB1 on broiler chickens, with DDPs exhibiting additional advantages in optimizing liver function and gut morphology.
本研究旨在评估水合硅铝酸钙钠(HSCASs)和废弃枣核(DDPs)作为黄曲霉毒素B1(AFB1)的膳食吸附剂对16至30日龄肉鸡生产性能和健康状况的影响。总共240只罗斯308直投式肉鸡被随机分为四个日粮组,每组10个重复:对照组日粮、含1000 ppb AFB1的对照组日粮、含0.5% HSCAS的AFB1污染日粮和含4% DDP的AFB1污染日粮。在AFB1污染的日粮中添加HSCASs或DDPs,在各个参数上都有显著改善,包括体重增加、饲料转化率提高、屠宰率升高、肾脏和脾脏相对重量降低、血清总蛋白、球蛋白和葡萄糖水平升高、血清丙氨酸转氨酶活性降低、肝脏蛋白质浓度和谷胱甘肽过氧化物酶活性升高,以及肝脏丙二醛含量和谷氨酸草酰乙酸转氨酶活性降低。此外,两种添加剂都导致回肠绒毛高度和表面积增加、表观氮校正代谢能消化率提高,以及肝脏和肾脏中AFB1残留量降低。此外,日粮中添加DDPs显著降低了肝脏相对重量,提高了血清白蛋白浓度,降低了血清碱性磷酸酶活性,提高了肝脏总抗氧化能力水平,并增加了回肠绒毛宽度。相反,日粮中添加HSCASs显著提高了表观粗蛋白消化率。总之,在受AFB1污染的日粮中添加HSCASs和DDPs可以减轻AFB1对肉鸡的毒性作用,DDPs在优化肝功能和肠道形态方面具有额外优势。
