Description
Technical field
The present invention relates to a kind of online method of enzymatically treating, particularly relate to a kind of online method of enzymatically treating that can improve the hybridized prussian carp efficiency of feed utilization, belong to the hybridized prussian carp field of feed processing.
Background technology
Hybridized prussian carp is the new object of a kind of crucian cultivation that the fish breeding expert of Inst. of Hydrobiology, Chinese Academy of Sciences succeeded in developing in 1976～1981 years, it is to utilize the upright pond crucian carp of Natural Gynogenesis to be female parent, take Singuo Red Carp as male parent, the filial generation of breeding through artificial insemination.Hybridized prussian carp has the characteristics such as growth is fast, individual greatly, strong stress resistance, demonstrates good economic characters in breeding production, is cultivated widely on China Jiangsu and other places at present.For the mixed feed of hybridized prussian carp, more research has been arranged, such as Chinese patent CN02115491.0, CN02115492.9 and 200610038034.5 etc.But, because the plant protein materials such as a large amount of dregs of beans that use, the dish dregs of rice, corn byproducts contain multiple ANFs in feed, such as (Refstie etc., 2005) such as trypsin ihhibitor, phytic acid, SNSPs, cause pond crucian carp that the digestive utilization ratio of feed is reduced.Forefathers' the enzyme preparations such as suitably adding non-starch polysaccharide enzyme in feed that studies show that can improve animal to the utilization rate (Steenfeldt etc., 2003) of vegetable protein.Usually enzyme preparation was added in the feed pre-mixing material in the past, through step pelletizing formings such as forage compounding, mixed once, ultramicro grinding, granulations, was then played a role behind the fish.But because the HTHP in aquatic feeds ultramicro grinding and the pelletization tends to cause the enzyme preparation inactivation, thereby reduced the result of use of enzyme preparation.Therefore, by adding method and the action time of improving enzyme preparation, thereby improve hybridized prussian carp the utilization rate tool of feed is of great significance.
