Abstract：
The objective of this study was to determine the effects of different lipid sources, with or without a probiotic, on the gastrointestinal tract, immune system and blood parameters of Ross 308 male chickens. In this study, 360 one-day-old chickens were randomly allotted to six treatments with six replicates. Experimental diets were: (1) control (CTL); (2) a diet containing 30 g/kg lipid from tallow (CTL+TLW); (3) a diet containing 30 g/kg lipid from soybean oil (CTL+SO); (4) the basal diet plus a probiotic (CTL+PRO), (5) a diet containing 30 g/kg tallow plus probiotic (TLW+PRO); and (6) a diet containing 30 g/kg soybean oil plus probiotic (SO+PRO). The percentage of liver and jejunum in the treatments that used tallow alone or tallow with probiotics had a significant increase as compared to the control. The villus height and crypt depth of the ileum and villus height/crypt depth in the treatments that used soybean oil and probiotic alone had a significant increase compared to the control. The weight of the spleen, bursa of Fabricius, and thymus in the treatments that used probiotics had a significant increase compared to the control. The amount of alkaline phosphatase and alanine aminotransferase as well as triacylglycerol in the treatment containing probiotic and its mixture with soybean oil had the least significant difference with the control. The results showed that the use of soybean oil, probiotics, and their mixture can improve intestinal morphology, strengthen the immune system, and reduce liver enzymes in chickens.
摘要：
这项研究的目的是确定不同脂质来源的影响，不管有没有益生菌，在胃肠道上，罗斯308公鸡的免疫系统和血液参数。在这项研究中,将360只一天大的鸡随机分配给6个处理,6个重复。实验饮食是：（1）对照（CTL）；（2）含有30g/kg牛脂的饮食（CTLTLW）；（3）含有30g/kg大豆油脂质的饮食（CTLSO）；（4）基础饮食加益生菌（CTLPRO），(5)含有30g/kg牛油加益生菌(TLW+PRO)的饮食;和(6)含有30g/kg大豆油加益生菌(SO+PRO)的饮食。与对照相比,在单独使用牛脂或牛脂与益生菌的处理中,肝脏和空肠的百分比具有显著增加。与对照相比,在单独使用大豆油和益生菌的处理中回肠的绒毛高度和隐窝深度以及绒毛高度/隐窝深度具有显著增加。脾脏的重量,法布里修斯的法萨,与对照组相比，使用益生菌的治疗中的胸腺和胸腺有显著增加。在含有益生菌及其与大豆油的混合物的处理中，碱性磷酸酶和丙氨酸氨基转移酶以及三酰甘油的量与对照的差异最小。结果表明,使用大豆油,益生菌，它们的混合物可以改善肠道形态，增强免疫系统，减少鸡肝酶.
