Problems solved by technology

The document "Grease Spraying Technology on the Surface of Pellet Feed" (Na Rina et al., Jiangxi Feed, No. 3, 2015) pointed out that due to the high freezing point temperature of the grease, if it is selected to be carried out after the pellets are cooled or when the pellet temperature is low, it is very difficult to It is easy to cause the oil to be only wrapped on the surface of the pellets. During the subsequent packaging, storage and transportation, there will be mutual friction and collision between the pellets, which will cause the surface of the pellets to peel off, resulting in insufficient nutrients and distortion of the formula.
At the same time, in order to make the appearance of the feed brighter, most of the existing technologies use the thermal spraying process of first spraying the oil and then cooling the feed, such as the patent CN101861948A, but after long-term feeding research, it is found that this processing technology is harmful to animals. Growth performance can be adversely affected resulting in inefficient feed farming
In addition, due to the unreasonable formula, the current feeding efficiency of peltago catfish is not high.

Embodiment 1

[0020] Embodiment 1: Feed nutritional composition comparison

[0021] In this embodiment, two different processing techniques (thermal spraying and cold spraying) are selected, and two different oil formulas are selected at the same time, namely the fish oil group and the soybean oil group. In the formulas, except for the addition of different oils and fats, other ingredients are the same; a total of four kinds are produced The different feeds were named cold spray-soybean oil group, cold spray-fish oil group, thermal spray-soybean oil group and thermal spray-fish oil group. The four feeds were equal in nitrogen and energy, respectively. The experimental raw materials were purchased uniformly and transported to each factory for production of feed. The parameters of the extruding process were consistent. , the results are shown in Table 1 and Table 2.

[0029] 1. Grouping

[0030] Grouping with reference to Example 1;

[0031] 2. Instruments and equipment

[0032] The volume of the breeding tanks used in the experiment is 200L, a total of 20, thermometers and electronic scales. The yellow catfish used in the experiment was purchased from Tangkou. Before the formal experiment, the yellow catfish was domesticated for 2 weeks to adapt to the environment. In the experiment, 1000 yellow catfish (about 6 g) with healthy constitution and uniform individual size were randomly divided into 5 treatment groups, each treatment group had 4 replicates, and each replicate had 50 yellow catfish. The feeding cycle was 60 days, and the apparently satiated animals were fed twice a day at 9:00 and 16:00, respectively. Weighing and sampling were recorded after the experiment. The breeding experiment was carried out in the ...

Abstract

The invention relates to the field of aquatic feed processing, and discloses pelteobagrus fulvidraco culturing feed and a preparation method thereof. The feed provided by the invention is prepared from Peru fish meal, bean pulp, flour, soya-bean oil, monocalcium phosphate, zeolite powder, saltwater fish compound premix, feed grade calcium propionate, vitamin C and an antioxidant. The pelteobagrus fulvidraco culturing feed provided by the invention adopts multiple proper components, fish oil commonly used in a traditional feed formula is removed, meanwhile, a cold spraying technology of cooling the feed first and then spraying grease is adopted for preparation, the prepared feed can reduce the feed coefficients and increase the specific growth rate and relative weight gain rate of pelteobagrus fulvidraco.

Description

technical field [0001] The invention relates to the field of aquatic feed processing, in particular to a feed for cultivating yellow catfish and a preparation method thereof. Background technique [0002] Pelteobagrus fulvidraco (scientific name: Pelteobagrus fulvidraco) is a fish belonging to the genus Pelteobagrus fulvidraco. Adult fish generally have a body length of about 20cm, with a straight ventral surface, a flattened rear half of the body, and a slender tail peduncle; a large and flat head, a short, blunt snout, slightly equal upper and lower jaws, a large mouth, a lower position, and two faces. There are villous tooth bands on the palate; the eyes are small and lateral. 4 pairs of barbels, the end of the nasal barbels can extend to the back of the eyes, 1 pair of maxillary barbels, the longest, 2 pairs of upper barbels, shorter than the maxillary barbels; the body is naked and scaleless, the lateral line is complete; omnivorous, staple food is benthic small animal...
