摘要

采用分阶段给药策略和减少日粮植酸酶,评估了一种新的细菌6-植酸酶变体(PhyG)在一日龄肉鸡中完全取代日粮补充无机磷酸盐(Pi)的能力。将1248只一日龄Ross 308肉鸡分配到24个围栏(52只/围栏,12只/日粮,雄性和雌性各6只),采用2×2因子安排(两种日粮,两种性别)的完全随机分组设计。日粮包括:(1)基于玉米、小麦和豆粕的阳性对照(PC),含有来自磷酸一钙的Pi和2000XU/kg木聚糖酶,以及;(2) 无无机磷酸盐(IPF)饮食相当于PC,但Ca减少(-2.0 g/kg),并分别在第0至11天(3.4 g/kg植酸酶-P(PP))、第11至22天(3.3 g/kg PP)和第22至42天(2.8至2.9 g/kg PP)补充3000、2000和1000 FTU/kg的PhyG。出于动物福利的原因,阴性对照不包括在内。在第11天、第22天和第42天采集两只鸟/围栏的胫骨。处理IPF在所有阶段保持或改善了平均日增重(ADG)、平均日采食量和饲料转化率(FCR)与PC的关系;IPF治疗组在第42天的体重高于PC组(+3.97%,P<0.01),在第0~42天的ADG组(+4.10%,P<0.01)。总体而言(第0~42日),IPF治疗改善了男性的FCR(比PC组低-5分,P<0.05),但女性没有。胫骨灰分在IPF和PC中始终相当,没有性别差异。总之,当作为一种分阶段给药策略应用于PP含量分级降低的饮食时,PhyG在雄性和雌性的所有生长阶段都完全取代了补充Pi。

A novel consensus bacterial 6-phytase variant added to phytate-rich diets totally replaced inorganic phosphate in broilers
The capacity of a novel bacterial 6-phytase variant (PhyG) to totally replace dietary supplemental inorganic phosphate (Pi) in broilers aged one day old was evaluated using a phased dosing strategy and reduction in dietary phytate. A total of 1,248 one-day-old Ross 308 broilers were assigned to 24 pens (52 birds/pen, 12 pens/diet, six each males and females) in a complete randomised block design with a 2×2 factorial arrangement (two diets, two genders). Diets comprised: (1) a positive control (PC) based on maize, wheat and soybean meal, containing Pi from monocalcium phosphate and 2,000 XU/kg xylanase, and; (2) an inorganic phosphate-free (IPF) diet equivalent to PC but with reduced Ca (-2.0 g/kg) and supplemented with PhyG at 3,000, 2,000 and 1000 FTU/kg from d 0 to 11 (3.4 g/kg phytate-P (PP)), d 11 to 22 (3.3 g/kg PP) and d 22 to 42 (2.8 to 2.9 g/kg PP), respectively. A negative control was not included for animal welfare reasons. Tibias were collected on d 11, 22 and 42 from two birds/pen. Treatment IPF maintained or improved average daily gain (ADG), average daily feed intake and feed conversion ratio (FCR) vs PC during all phases; Body weight was higher in the IPF treatment than the PC at d 42 (+3.97%, P<0.01) and ADG during d 0 to 42 (+4.10%, P<0.01). Overall (d 0 to 42), treatment IPF improved FCR in males (-5 points vs PC, P<0.05) but not females. Tibia ash was equivalent in IPF and PC throughout, with no gender differences. In conclusion, when applied as a phased dosing strategy to diets with graded reduction in PP content, PhyG totally replaced supplemental Pi during all growth phases in males and females.
