Soft granular feed and preparation method and application thereof

Abstract

The invention belongs to the technical field of feeds, and discloses a soft granular feed and a preparation method and application thereof. The feed comprises the following components: a protein source raw material, a fat source raw material, a sugar source raw material and a feed adhesive, and the feed adhesive comprises xanthan gum and glutamine transaminase. The feed provided by the invention adopts the xanthan gum and the glutamine transaminase as feed adhesives, and the xanthan gum and the glutamine transaminase have a synergistic effect, so that the feed prepared in a low-temperature extrusion mode is good in water resistance and does not disperse after being soaked in water; the activity and functional components of the feed are not affected by high temperature, and the feed is good in palatability and balanced in nutrition, has the advantages of being easy to eat, digest and absorb and the like, and can promote rapid growth of aquatic animals. The feed is prepared by directly mixing all the components and carrying out primary granulation. Compared with the common fermented feed, the operation is simple, and the production cost is lower.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a soft granular feed and a preparation method and application thereof. Background technique [0002] At present, the industrialized farming of prawns has become large-scale and productive, forming the current high-density, large-scale and intensive intensive farming model. However, the survival rate of shrimp fry is still relatively low; and with the increase of breeding density, the incidence of aquatic animal diseases and insect pests is often higher. In the early days of aquaculture, antibiotics were often used to prevent and control shrimp diseases, but the long-term use of antibiotics has brought many negative effects, such as the emergence of drug-resistant bacteria and the destruction of the microbial balance in the intestinal tract of shrimp, etc., which will cause a series of environmental and social problems , so it is necessary to develop sustainable alternat...

Problems solved by technology

However, the traditional shrimp feed pelleting process involves high-temperature conditioning and drying processes, which can easily affect these functional ingredients, resulting in a decrease in content or activity. Therefore, it is necessary to develop a low-temperature pelleting method for this type of functional health feed. craft

However, due to the lack of gelatinization of starch, the water resistance of low-temperature granulated granules is generally poor, and it is difficult to meet the slow feeding habits of prawns. At the same time, the added functional substances will also be lost due to the collapse of granules, and the transfer efficiency is greatly reduced.
