Expanded compound feed for siniperca chuatsi and preparation method thereof

Abstract

The invention discloses an expanded compound feed for siniperca chuatsi and a preparation method thereof. The feed is mainly prepared from raw materials, a conventional auxiliary material and other auxiliary materials; the raw materials comprise fish meal, soybean meal, corn gluten meal, vital gluten and haemocyte powder, the conventional auxiliary material is starch, and the other auxiliary materials comprise cuttlefish paste, a yeast extract, potassium sorbate, fish oil, vegetable oil, lecithin, 50% choline chloride, premix for fishes, zeolite powder and monocalcium phosphate. According to the preparation method of the expanded compound feed for the siniperca chuatsi, after feed granules are prepared, vacuum spraying is conducted twice in order to spray nutrient components taking vegetable oil as the main material in the feed granules, attractant components which have the attractant effect and take the fish oil as the main material are sprayed to the exteriors of the feed granules, and the attractant effect is enhanced while the vegetable oil taste of the inner layer is shielded. The expanded compound feed prepared through the method has the advantages that nutrition is balanced, and the mouthfeel and the smell are close to those of live fishes; the expanded compound feed is not prone to be swollen after being put into water, and the bait coefficient can be decreased.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to an extruded compound feed for mandarin fish and a preparation method thereof.

Problems solved by technology

Although the mandarin fish feed in this patent has richer nutrition than the traditional feed and can meet the nutritional needs of mandarin fish feeding, due to its simple production process and no appropriate amount of binder, the feed is easy to swell and disperse after entering the water. In the water body, not only cannot provide food for mandarin fish, but will cause eutrophication pollution of the water body
