Description

Grass carp and black carp overwintering feed and production method thereof Technical Field The invention relates to a grass carp and black carp overwintering feed and a production method thereof, and belongs to the technical field of fish feeds. Background The fish such as grass carp, black carp, crucian carp and longsnout catfish can die in a large quantity after spring, and the main symptoms are that lips are ulcerated, eyesocket gill covers and body surfaces are engorged, eyeballs are protruded, scales are erected, and part of diseased fish is infected with water mould secondarily. Anatomical findings show that the diseased fish is accompanied with symptoms such as white and yellow liver, intestinal tract bleeding and inflammation, black spleen and the like, and the disease fish is commonly called as overwintering syndrome. This condition causes huge economic loss for farmers and also causes environmental pollution problems, which are urgently needed to be solved. The root cause of the overwintering syndrome is the weak constitution and poor disease resistance of the overwintered fish. To solve this problem, existing fish feeds, such as those disclosed in the patent application CN 117044845A and the patent application CN 116268205A, can prevent and treat overwintering syndrome to a certain extent, but still have the following drawbacks: Firstly, the grass carp feed additive disclosed by the invention is CN 116268205A, does not consider the important influence of feed nutrition and energy on the health of fish during overwintering, and cannot fundamentally solve the overwintering syndrome. Secondly, the nutritional requirements and the digestive physiological characteristics of the fish under the condition of low water temperature in winter are not considered. The nutrition provided by the feed discovered by CN 117044845A has long digestion time and low digestion and absorption rate under low water temperature in winter, and can not effectively provide nutrition and energy for overwintering fish. Thirdly, the feeding habit characteristics of overwintering fish are not considered. In winter, the upper water temperature is low, fish floats to the water surface less to eat, and the ingestion desire is poor. Due to the temperature difference of different water layers, overwintering feeding of swelling buoyancy materials can cause feed waste, and the temperature difference can also cause stress to fish to influence health. The feed disclosed by the invention of CN 117044845A is a puffed floating material, and the phagostimulability of the feed is not considered. Fourth, no consideration is given to the effect of feed morphology on digestion and health. Common feed forms comprise pellet feed, expanded floating feed and expanded submerged feed, have certain hardness, long core penetration time and slow disintegration in stomach and intestine, can cause mechanical damage to fragile digestive tracts of fish in winter, and can influence digestion and absorption of nutrient substances. Fifth, the comprehensiveness of the health restoration and improvement of the overwintering fish is not fully considered. In order to prevent and treat the overwintering syndrome, the health restoration and promotion of the overwintering fish are required to be carried out from four aspects of liver, intestinal canal, anti-stress and immunity enhancement, and the feed disclosed by the CN 117044845A does not fully consider the aspects. Therefore, a new overwintering feed needs to be developed to solve the problems of unreasonable nutrition, unreasonable shape and unreasonable health care existing in the existing feed. Disclosure of Invention The invention aims to provide a grass carp and black carp overwintering feed, which solves the problems that the existing overwintering feed cannot effectively provide nutrition and energy for overwintering fishes and is difficult to digest and absorb. The technical scheme of the invention is as follows: The grass carp and black carp overwintering feed comprises an expanded master batch, wherein the expanded master batch comprises the following components in parts by weight: 0-5 parts of fish meal and 15-25 parts of bean pulp 20-45 Parts of rapeseed meal and 5-10 parts of cotton seed meal or cotton seed protein 1-6 Portions of pricklyash peel seed and 1-18 portions of flour 1-15 Parts of rice bran and 20-35 parts of turmeric powder 1-2 Parts of phosphatide oil and 5-20 parts of rare earth silicon mineral powder 0.5-1 Of premix and 5-10 of functional additive The functional additive consists of the following components in parts by weight: 0.2-0.5 methionine 0.05-0.2 threonine 0.05-0.2 lysine, Taurine 0.05-0.2 bile acid 0.02-0.1 mannooligosaccharide 2-4 2-3 Rare earth 0.5-2 vitamin C ester 0.05-0.2 turmeric powder Tributyrin 0.05-0.1 cellulase 50 ten thousand IU Pectase 50 ten thousand IU The production method of the grass carp and black carp overwintering feed comprises the following steps: processi
