Problems solved by technology

[0004] At present, with the popularization of intensive aquaculture, domestic grass carp feed is basically based on compound feed, and most of the raw materials use soybean meal, cotton meal, and rapeseed meal as the main protein source, resulting in soft meat, high water content, and muscle. The freshness is not enough, the taste and flavor are obviously reduced, the shreds are brittle, and the cooking is easy to rot, which affects the sustainable development of grass carp farming

Embodiment 1

[0020] To prepare the feed of the present invention, the raw material consumption (unit: Kg) is as follows in Table 1 in each formula.

[0021] raw material

[0022] The method for preparing the feed of the present invention with the above-mentioned raw materials is: (1) pulverizing the non-powder material in the above-mentioned raw materials; (2) fully stirring all the raw materials with a mixer; (3) making the above-mentioned mixture into granules according to a conventional method The feed is the finished product.

Embodiment 2

[0024] With the feed made from formula 3 and formula 4 of Example 1, the grass carp about 850g was fed for 150 days in the farm, wherein the common grass carp commercial feed was the control group, and the formula 3 feed was the experimental group 1. The feed of formula 3 was experimental group 2, and each group was repeated three times, and each pond was fed with 100 grass carp. The breeding effects are shown in Table 1 to Table 4.

[0025] The common grass carp commercial feed formula used in the control group was: soybean meal 80Kg, cotton meal 240Kg, rapeseed meal 240Kg, secondary powder 293Kg, soybean oil 20Kg, bran 100Kg, calcium dihydrogen phosphate 15Kg, choline chloride 2Kg, prepowder 10Kg. Its preparation method embodiment 1.

[0026] The grass carp of about 850g was fed for 150 days in the experimental fish farm of Hunan Agricultural University with the above-mentioned feed for 150 days. Those who fed the common grass carp commercial feed were the control group, and...

Abstract

The invention discloses a feed for improving meat quality of fish and use thereof. The feed comprises the following raw materials in part by weight: 60 to 80 parts of broad beans and dehulled broad beans, 2 to 6 parts of bean pulp, 6 to 13 parts of cottonseed meal and 6 to 12 parts of rapeseed meal. The feed disclosed in the invention can overcome the drawbacks of looseness of meat quality of grass carps, low freshness of muscle and poor mouthfeel under concentrated breeding, effectively improve the bending strength of the muscle fibril and diameter of muscle fibers of grass carps, improve the compactness and toughness of the meat of the grass carps, improve the delicious amino acid content in muscle and greatly lower breeding cost of grass carps and is suitable for industrial production.

Description

technical field [0001] The invention relates to a feed, in particular to a feed for improving the quality of fish meat. At the same time, the invention also relates to an application method of the feed, which belongs to the technical field of aquatic feed. Background technique [0002] Grass carp (Ctenopharyngodon idellus) is one of the main species of freshwater aquaculture in my country. It is widely distributed in the rivers and rivers in the northeast, east, central and southern regions of China. Become the leader in conventional breeding varieties. However, people have long considered grass carp to be a typical herbivorous fish, fed with green fodder, dry grass, aquatic grass and crop stalks. Due to the high crude fiber content of these vegetable feeds and the lack of effective nutrients such as protein, it is difficult for grass carp to digest and absorb after eating. After the excrement of grass carp enters the water, a large amount of organic matter rots and ferment...
