據(jù)了解，內(nèi)切-1,4-β-木聚糖酶、內(nèi)切-1,4-β-葡聚糖酶和木葡聚糖特異性內(nèi)切-β-1,4-葡聚糖酶是由桔綠木霉（Trichoderma citrinoviride）DSM 33578生產(chǎn)的。

 

　　經(jīng)過評(píng)估，專家小組認(rèn)為在建議的使用條件下該添加劑對(duì)目標(biāo)物種、消費(fèi)者和環(huán)境是安全的，該添加劑作為動(dòng)物技術(shù)添加劑有可能對(duì)所有豬和所有家禽有效。部分原文報(bào)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, endo-1,4-beta-glucanase and xyloglucan-specific-endo-beta-1,4-glucanase (produced with Trichoderma citrinoviride DSM 33578) (Huvezym® neXo), intended to be used as a zootechnical feed additive (functional group: digestibility enhancers) for all Suidae and all poultry at the recommended application level 1500 endo-pentosanase units (EPU), 100 cellulase unit (CU) and 100 xyloglucanase unit (XGU)/kg of complete feed. The additive is available in granulated (Huvezym® neXo 100 G) and liquid (Huvezym® neXo100 L) forms, and it is authorised for use in reproductive sows and poultry for fattening, poultry reared for laying and reared for breeding, and ornamental birds. In previous opinions, the FEEDAP Panel concluded that Huvezym® neXo is safe for the target species, consumers and the environment. Additionally, the FEEDAP Panel concluded that Huvezym® neXo in either form is not an irritant to the skin and eyes; the liquid form is not a skin sensitiser, but the solid form should be considered a potential skin sensitiser. Both forms of the additive are considered respiratory sensitisers. However, in the previous assessments, the Panel could not conclude on the efficacy of weaned piglets and laying hens. Considering the previously and newly submitted data the Panel concluded that the additive has a potential to be efficacious as a zootechnical additive for all porcine species and all poultry under the proposed conditions of use.
