Special pelteobagrus fulvidraco feed being reasonable in formula and low in case-fatality rate

Abstract

The invention discloses a preparation technology of a special pelteobagrus fulvidraco feed being reasonable in formula and low in case-fatality rate. The preparation technology comprises the followingsteps of mixing and stirring nanometer silicon dioxide with an ethanol water solution, adding sepiolite powder and ethanediol, performing ultrasonic vibration, performing filtering, and performing drying so as to obtain pretreated stone powder; uniformly mixing ant powder with pork scraps, squid powder, yellow mealworms, corn flour, grass meal, rapeseed meal, luffa flowers and the pretreated stone powder, and performing crushing so as to obtain a pretreatment main material; and under the state of stirring, adding lard, sesame oil, betaine, pomelo peel powder, soybean phospholipid and a premixto the pretreated main material, performing uniform stirring, adding water, performing mixing, inflating steam, performing curing, performing granulation, and performing cooling so as to obtain the special pelteobagrus fulvidraco feed being reasonable in formula and low in case-fatality rate. The special pelteobagrus fulvidraco feed disclosed by the invention is rich in nutrition and reasonable in formula, is not liable to disperse when being in contact with water, and is conveniently eaten by the pelteobagrus fulvidraco; and according to the special pelteobagrus fulvidraco feed, the immunityof the pelteobagrus fulvidraco can be effectively improved, the disease resistance of the pelteobagrus fulvidraco is strengthened, and the case-fatality rate of the pelteobagrus fulvidraco is low.

Description

technical field [0001] The invention relates to the technical field of yellow catfish feed, in particular to a special feed for yellow catfish with reasonable formula and low fatality rate. Background technique [0002] Yellow catfish belongs to the order Siluriformes, the family Oleidae, and the genus of yellow catfish. Commonly known as yellow cured, yellow bone fish. The body is long, the abdomen is flat, and the back of the body is slightly flattened. The head is large and flat, the snout is round and blunt, the mouth is large and inferior, and the upper and lower jaws have fine hairy teeth, and the eyes are small. 4 pairs of barbels, maxillary barbels are particularly long in most species. No scales. Both the dorsal and pectoral fins have well-developed spines, which can make sounds when the spines move. The adipose fins are short. The body is blue-yellow, and most species have irregular brown markings; each fin is gray-black with yellow. It is a small bottom fis...

Problems solved by technology

[0003] At present, with the popularization of artificial feeding, the yellow catfish is generally fed with ordinary fish feed, resulting in slow growth and poor physical fitness of the yellow catfish. During the breeding process of the yellow catfish, the disease occurs frequently, and the mortality rate increases year by year.
