Description

A kind of pellet feed for adult peltedelachus vacheronii

technical field

The invention relates to the technical field of animal breeding, in particular to a pellet feed for adult peltedelachus vacheronii.

Background technique

China is a big freshwater fishery country in the world. In 2008, the total output of freshwater fish farming in my country was 19.98 million tons, accounting for 70% of the total fish output in my country. Due to the zero-growth marine fishing policy and the implementation of closed fishing seasons, the current production of marine fish in my country has stabilized, while the production of freshwater fish has shown continuous growth. The freshwater fish industry has received high attention from the society. Without a high-level feed industry, there will be no healthy and sustainable breeding industry. The long-term practice of developed countries has proved that the contribution rate of nutrition research and feed development and application in the development of aquaculture is about 40%. In 2008, my country's aquatic feed was less than 20 million tons, and the rest were fed directly by feed raw materials or fresh miscellaneous fish. This not only wastes my country's limited feed resources, but also causes serious pollution to the water environment, breeds diseases, and endangers food hygiene. safety, threatening the sustainable development of my country's aquaculture industry. Therefore, research and development of safe, efficient, low-pollution pollution-free compound feed is the development trend of fish feed technology at home and abroad.

Pelteobagrus vachelli , also known as Pelteobagrus vachelli , is a major small economic fish widely distributed in the main and tributaries of the Yangtze River in the Three Gorges Reservoir area, and it is also the main catch of fishes in the waters of the Three Gorges Reservoir area of the Yangtze River , because of its rich amino acid content, high muscle fat content, fresh and tender meat, and no intermuscular thorns, it is deeply loved by consumers. In recent years, its market price has remained high, and the price has remained at 24-32 yuan per kilogram for a long time. It has become a high-end freshwater aquatic product that is in short supply and has high breeding benefits. Due to the relatively slow growth of Pelvis vacheronii, coupled with the lag of artificial compound feed preparation technology, the growth rate of farmed fish is low or the color of the muscle becomes poor, which seriously affects the breeding and economic benefits of its adult fish. Therefore, the development of effective artificial compound feed is an important link to promote the rapid growth of farmed fish.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned defects existing in the prior art, and to provide a kind of pellet feed for adult peltatus vacheronii.

A kind of pelleted feed for adult fish of peliotus vacheronii of the present invention, its component and mass percentage content are as follows:

Peeled soybean meal 25-30%, rapeseed meal 20-25%, cotton meal 15-20%, flour 15-20%, steam fish meal 5-10%, corn gluten meal 3-5%, low-temperature yeast powder 2-5% %, seaweed powder 1-3%, soybean lecithin 1-3%, fish oil 1-3%, Bacillus subtilis 0.1-0.3%, vitamin C 0.1-0.3%, methionine zinc 0.03-0.05%, ethoxyquinoline 0.05-0.08%.

The preparation method of a kind of pelleted feed for adult fish of pelican varskini of the present invention is simple: each component is weighed, pulverized respectively, passed through a 60-mesh sieve, mixed evenly with soybean lecithin and fish oil, and then granulated to obtain the present invention. Invented pellet feed.

The granular feed of the present invention has good stability in water, low dissolution loss rate, and little water pollution; it can obviously improve the color of the peltrelative catfish and promote the growth of the fish; and the source of raw materials used is stable, the price is low, and the production process is simple; The mass percentages of protein and fat are 32-36% and 4-7% respectively.

Detailed ways

Example 1:

Weigh 28 kg of peeled soybean meal, 22 kg of rapeseed meal, 16 kg of cotton meal, 15.72kg of flour, 7 kg of steamed fish meal, 3 kg of corn gluten meal, 3 kg of low-temperature yeast powder, 2 kg of seaweed powder, and 0.1 kg of Bacillus subtilis , vitamin C 0.1 kg, methionine zinc 0.03 kg and ethoxyquinoline 0.05 kg, the above components were pulverized respectively, passed through a 60-mesh sieve, mixed evenly with 1kg soybean lecithin and 2kg fish oil, and then granulated to obtain The granular feed of the present invention.

In the indoor recirculation culture system of two experimental sites in different regions of the country, the initial weight of the Pediatric catfish was 12.4 ± 1.2 g. The control group used the commercial feed with the best breeding effect on the market at present, and the feed used in the experimental group was the above-mentioned tile fish. Peeled catfish adult fish pellet feed. The protein content of the feed used in the control group and the experimental group was the same, both 36% (mass percentage), and there were 3 replicates. Know after the feeding experiment of 56 days, throw something and feed the specific growth rate of the Peeled catfish of the present invention's feed all is 2.38%/day～2.52%/day, significantly higher than the matched group (1.95%/day) that adopts commercial feedstuff. day~2.13%/day); the liver lipid content of the experimental group was 7.15%, which was significantly lower than that of the commercial feed group (9.38%); the muscle color of the experimental group was closer to that of the commercial feed group Its natural growth color is dark brown on the back, yellow on the side of the body, and light yellow on the abdomen. Moreover, the activities of hepatopancreas alanine aminotransferase (GPT), aspartate aminotransferase (GOT) and superoxide dismutase (SOD) of the Peltella vacheronva with the above-mentioned experimental diet (86.36 U g ^-1 protein, 115.98 U g ^{-1 1} protein and 62.35 U mg ^-1 protein) were significantly higher than the commercial feed group (61.35 U g ^-1 protein, 87.24 U g ^-1 protein and 34.68 U mg ^-1 protein).

Example 2:

Weigh 25 kg of peeled soybean meal, 23 kg of rapeseed meal, 15 kg of cotton meal, 16.5kg of flour, 9 kg of steamed fish meal, 3.5 kg of corn gluten meal, 2.5 kg of low-temperature yeast powder, 1.5 kg of seaweed powder, and 0.2 kg of Bacillus subtilis , vitamin C 0.2 kg, methionine zinc 0.05 kg and ethoxyquinoline 0.05 kg, the above components were pulverized respectively, passed through a 60-mesh sieve, mixed evenly with 2kg soybean lecithin and 1.5kg fish oil, and then granulated, Obtain the granular feed of the present invention.

Two field breeding experiments were carried out in different regions of the country. The initial weight of the peltaceae was 17.6±1.8 g. The breeding experiments of the two fish and the experiment of the control group were carried out in 3 ponds respectively. The average area of each pond All are 6 mu, and the feed that the control group uses adopts the best commercial feed of breeding effect on the market, and the feed that the experimental group uses adopts the above-mentioned yellow catfish adult fish feed of the present invention, and the content of protein is identical in two kinds of feeds, both It is 34% (mass percentage). After 60 days of feeding experiment, the growth rate of the Peltaceae varschii fed with the experimental feed was 2.86%/day~2.92%/day, which was significantly higher than that of the control group (2.69%/day~2.76%/day) with the commercial feed. /day); the feed coefficient (1.62-1.65) of the feed used in the experimental group was significantly lower than that of the commercial feed group (1.71-1.78). Moreover, the muscle color, liver lipid content, and hepatopancreas alanine aminotransferase (GPT), aspartate transaminase (GOT) and superoxide dismutase (SOD) activity indexes of the peltatorium waschii fed the above-mentioned experimental diet were all better than those of the commercial diet. feed group.

The invention can not only promote the growth of the yellow catfish and reduce the breeding cost, but also protect the germplasm resources of the yellow catfish in the upper reaches of the Yangtze River and maintain the sustainable development of the yellow catfish culture industry.
