Wheat bran (WB) was co-fermented with Aspergillus oryzae and phytase (Phy) to determine whether co-fermentation improve WB phosphorus and fiber utilization in Isa-brown layers.
A total of 112 Isa brown layer were randomly divided into 7 treatments with 8 replicates per a treatment and 2 hens per a replicate. The treatments included basal diet (control), basal diet supplemented with 250 unit/kg Phy (control+Phy), diet with 10% WB (10% WB), diet with 5% WB and 250 unit/kg Phy (5% WB+Phy) diet with 10% WB and 250 unit/kg Phy (10% WB+Phy), diet with 5% fermented WB supplemented with molasses and phy (PCFWH) and 125 unit/kg Phy (5% PCFWH), and diet with 10% PCFWH (10% PCFWH). The intestinal microbial population, intestinal morphology, serum antioxidant enzyme activities, and excreta phosphorus content were assessed.
In PCFWH, spore counts, protease activity, xylanase activity, and ferulic acid were 8.50 log/g dry matter (DM), 190 unit/g DM, 120 unit/g DM, and 127 μg/g, respectively. Xylobiose and xylotriose were released in PCFWH, while they were not detectable in WB. Antioxidant capacity was also enhanced in PCFWH compared to WB. The 10% WB+Phy and 10% PCFWH groups produced higher egg mass, but hens fed 5% WB+Phy had the lowest amount of feed intake. Eggs from 10% PCFWH had better eggshell weight, eggshell strength, and eggshell thickness. Birds fed with 10% PCFWH also had higher serum superoxide dismutase and catalase activities. Compare to control, 10% PCFWH significantly reduced excreta phosphorus content.
Diet inclusion of 10% PCFWH improved egg quality, antioxidant status, and excreta phosphorus content of laying hens.
将麦麸（WB）与米曲霉和植酸酶（Phy）共同发酵，以确定共同发酵是否能提高艾维茵褐壳蛋鸡对WB中磷和纤维的利用率。
总共112只艾维茵褐壳蛋鸡被随机分为7组，每组8个重复，每个重复2只母鸡。处理组包括基础日粮（对照组）、添加250单位/千克Phy的基础日粮（对照组+Phy）、含10%WB的日粮（10%WB）、含5%WB和250单位/千克Phy的日粮（5%WB+Phy）、含10%WB和250单位/千克Phy的日粮（10%WB+Phy）、含5%添加糖蜜和Phy的发酵WB的日粮（PCFWH）和125单位/千克Phy（5%PCFWH）以及含10%PCFWH的日粮（10%PCFWH）。评估肠道微生物种群、肠道形态、血清抗氧化酶活性和排泄物磷含量。
在PCFWH中，孢子数、蛋白酶活性、木聚糖酶活性和阿魏酸分别为8.50 log/g干物质（DM）、190单位/g DM、120单位/g DM和127μg/g。PCFWH中释放出木二糖和木三糖，而在WB中未检测到。与WB相比，PCFWH的抗氧化能力也有所增强。10%WB+Phy和10%PCFWH组产蛋量更高，但采食5%WB+Phy的母鸡采食量最低。来自10%PCFWH组鸡蛋的蛋壳重量、蛋壳强度和蛋壳厚度更好。采食10%PCFWH的鸡血清超氧化物歧化酶和过氧化氢酶活性也更高。与对照组相比，10%PCFWH显著降低了排泄物磷含量。
日粮中添加10%PCFWH可改善蛋鸡的蛋品质、抗氧化状态和排泄物磷含量。
