ABSTRACT The aim of current trial was to investigate the efficacy of a new plant-specific fungus (Piriformospora indica) rich in mannan as a fungal feed additive in chicks. A control diet was formulated and 5 incremental levels (0.1, 0.2, 0.4, 0.6, and 0.8 g/kg of diet) of P. indica and 750 mg/kg of diet yeast culture or 500 mg/kg L. acidophilus were added to the control diet. Different characteristics and responses were measured during experimental period. P. indica inclusion increased BW and significantly decreased FCR (P ≤ 0.01) but had no effect on feed intake. P. indica significantly enhanced blood glucose level and reduced cholesterol, LDL, total protein, albumin and uric acid concentration of plasma (P ≤ 0.01; P ≤ 0.05). Higher villus height and thinner crypt depth were obtained in chicks fed 0.6 g P. indica in comparison with the chicks fed control diet or diets containing Lactobacillus acidophilus or yeast culture. Protein digestibility was enhanced in chicks fed yeast culture or 0.1, 0.2 and 0.4 g of P. indica (P ≥ 0.001). Gizzard pH was increased and ileal pH was decreased and the relative weight of carcass, bursa of Fabricius and thymus were increased by inclusion of P. indica.

评估富含甘露寡糖的植物特异性真菌（Piriformospora indica）作为微生物饲料添加剂对雏鸡生长性能、蛋白质消化率、血浆特性、肠道菌群和形态的功效

摘要 当前试验的目的是研究一种富含甘露聚糖的新型植物特异性真菌（Piriformospora indica）作为真菌饲料添加剂对鸡的功效。配制对照日粮并将 5 个增量水平（0.1、0.2、0.4、0.6 和 0.8 g/kg 日粮）的籼稻和 750 mg/kg 日粮酵母培养物或 500 mg/kg 嗜酸乳杆菌添加到控制饮食。在实验期间测量了不同的特性和响应。加入籼稻增加了体重并显着降低了 FCR（P ≤ 0.01），但对采食量没有影响。P. indica 显着提高血糖水平并降低血浆胆固醇、低密度脂蛋白、总蛋白、白蛋白和尿酸浓度（P ≤ 0.01；P ≤ 0.05）。饲喂 0.6 g P 的雏鸡获得更高的绒毛高度和更薄的隐窝深度。与饲喂对照日粮或含有嗜酸乳杆菌或酵母培养物的日粮的雏鸡相比。饲喂酵母培养物或 0.1、0.2 和 0.4 g 籼稻的雏鸡的蛋白质消化率提高（P ≥ 0.001）。加入籼稻后，胼的pH值增加，回肠的pH值降低，胴体、法氏囊和胸腺的相对重量增加。
