The aim of this study was to evaluate carcass quality and analyze gastrointestinal functional status, ochratoxin A (OTA) accumulation in tissues and organs, and the health status of turkeys fed diets contaminated with OTA and supplemented with synbiotic preparations in comparison with commercial probiotic feed additives. The research involved 120 female BIG 6 turkeys, divided into six treatment groups (five replicates, four birds per replicate). Wheat naturally contaminated with OTA (662.03 μg/kg) was used in turkey diets. Turkeys in group 1 received an OTA-contaminated diet without additives. Groups 2 and 3 received 0.4 g/kg of probiotic preparation BioPlus 2B or Cylactin. Groups 4, 5, and 6 received 0.5 g/kg of synbiotics S1, S2, or S3. The following parameters were monitored: growth performance, carcass quality, gastrointestinal tract structure and digesta pH, health status, and concentrations of OTA in the blood and tissues of turkeys. The study found no significant differences in the growth performance and carcass quality of turkey. However, the introduction of probiotics or synbiotics into OTA-contaminated feed mixtures resulted in a reduced pH of the digesta in certain sections of the turkey digestive tract ( < 0.05). Additionally, the tested synbiotic additives significantly reduced liver weight in turkeys at weeks 6 and 15 ( < 0.05). The addition of probiotic and synbiotic preparations based on lactic acid bacteria strains, inulin, and yeasts to OTA-contaminated diets in commercial turkey farming may improve health status ( < 0.05) and reduce mycotoxin accumulation in organs and tissues of poultry ( < 0.05).
本研究的目的是评估火鸡的胴体品质,分析其胃肠道功能状态、组织和器官中赭曲霉毒素A(OTA)的蓄积情况,以及与商业益生菌饲料添加剂相比,饲喂受OTA污染且添加了合生元制剂的日粮的火鸡的健康状况。该研究涉及120只雌性BIG 6火鸡,分为六个处理组(每组五个重复,每个重复四只火鸡)。火鸡日粮中使用了天然受OTA污染(662.03μg/kg)的小麦。第1组火鸡接受不含添加剂的受OTA污染的日粮。第2组和第3组分别接受0.4g/kg的益生菌制剂BioPlus 2B或Cylactin。第4、5和6组分别接受0.5g/kg的合生元S1、S2或S3。监测了以下参数:生长性能、胴体品质、胃肠道结构和食糜pH值、健康状况以及火鸡血液和组织中OTA的浓度。研究发现,火鸡的生长性能和胴体品质没有显著差异。然而,在受OTA污染的饲料混合物中添加益生菌或合生元会导致火鸡消化道某些部位的食糜pH值降低(P<0.05)。此外,在第6周和第15周时,测试的合生元添加剂显著降低了火鸡的肝脏重量(P<0.05)。在商业火鸡养殖中,向受OTA污染的日粮中添加基于乳酸菌菌株、菊粉和酵母的益生菌和合生元制剂可能会改善健康状况(P<0.05)并减少家禽器官和组织中霉菌毒素的蓄积(P<0.05)。
