Embodiment 4

[0024] The extruded feed premix finished product for bream prepared in Example 2 is added to the complete feed for bream in a proportion of 1% by weight (wherein the percentage by weight of the components contained in the complete feed for bream of 99% is : Fish meal 2%, soybean meal 5%, rapeseed meal 25%, cottonseed meal 25%, rice bran 12%, wheat 15%, calcium dihydrogen phosphate 2%, corn DDGS 7%, bentonite 2%, zeolite powder 3%, Soybean oil 1%), stirred and mixed evenly, pulverized by a superfine pulverizer, moved the pulverized mixed material into a modulator for steam modulation, and then moved the modulated mixed material into an extrusion extruder granulator to make feed pellets. The extruded feed was applied to a bream farmer in Heqiao Town, Yixing City, Jiangsu Province to carry out pond breeding experiment. The average water depth of the fish pond is 2.5 meters, the stocking size is 15-20 fish / kg, and the stocking density is 1500-1800 fish / mu. The total stocking is 2 ...

Abstract

The invention relates to an expanded feed premix for a Parabramis pekinensis as well as a preparation method and an application for the expanded feed premix. The expanded feed premix consists of compound vitamins, compound trace elements and other functional additives. The compound vitamins comprise vitamin A acetic ester, vitamin D3, vitamin E acetic ester, vitamin K3, vitamin B1 and the like. The compound trace elements comprise ferrous sulfate, magnesium sulfate, copper glycine, zinc methionine, manganese glycine and the like. The other functional additives comprise DL-methionine, L-lysine, mannan oligosaccharide, maltooligosaccharide and selenium-enriched yeast. The expanded feed premix for the Parabramis pekinensis provided by the invention is added to a complete feed for the Parabramis pekinensis in a 1% proportion of weight percentage during feeding. The expanded feed premix provided by the invention is scientific in proportioning and comprehensive in nutrition, and loss of nutritional materials caused by an expanded process of the feed can be supplemented, so that a weight increment rate of the Parabramis pekinensis is remarkably improved, and a bait coefficient is reduced, and the expanded feed premix has a remarkable growth-prompting effect, and is safe in long term use, and has no toxic and side effects.

Description

technical field [0001] The invention belongs to the technical field of feed premix, in particular to an extruded feed premix for bream. Background technique [0002] Bream (Parabramis pekinensis), belonging to Cyprinidae, Cyprinidae, Bream subfamily, and genus Bream, is commonly known as Changchun bream, bream flower, edge fish, and grass bream. It is widely distributed in rivers and lakes in major water systems in my country. Bream is a herbivorous fish that feeds on aquatic plants, diatoms, filamentous algae, etc., and also eats a small amount of plankton and aquatic insects. Bream is loved by people because of its tender meat, rich fat and delicious taste. It is one of the main freshwater cultured fish in China. In Jiangsu, bream is cultivated in a large range. [0003] With the development of the aquaculture industry in the direction of scale, intensification and specialization, the requirements for aquatic feed are also getting higher and higher, and the increase in t...
