　　据了解，这种内切-1,4-��-木聚糖酶由Komagataella phaffii ATCC PTA-127053生产的。经过评估，专家小组认为该添加剂在建议的最低水平下，有可能有效提高所有家禽的消化率。部分原文报道如下：

　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of endo-1,4-beta-xylanase produced by Komagataella phaffii ATCC PTA-127053 (Xygest ?HT) as a zootechnical feed additive (functio nal group: digestibility enhancers) for all poultry. In a previous opinion, the FEEDAP Panel co ncluded that Xygest ?HT is safe for all poultry, consumers, and the environment. The additive is not co nsidered to be irritant to eyes and skin but a dermal and a respiratory sensitiser, although exposure by inhalation is unlikely. The Panel also co ncluded that the additive has the potential to be efficacious in laying hens at 45,000 U/kg complete feed and this co nclusion was extrapolated to all laying poultry. However, the Panel could not co nclude on the efficacy of the product in growing poultry at the proposed co nditions of use. In the current application, the applicant provided an additio nal efficacy trial in chickens for fattening. The results showed a higher apparent me tabolisable energy (nitrogen corrected) in chickens fed the additive at the minimum proposed level of 30,000 U/kg complete feed when compared to the co ntrol group. Co nsidering the previously submitted studies in laying hens and chickens for fattening, and the newly submitted study in chickens for fattening, the Panel co ncluded that Xygest ?HT has the potential to be efficacious to enhance digestibility in all poultry at the correspo nding proposed minimum levels in feed.
