Embodiment 1

[0020] To prepare the feed of the present invention, the amount of raw materials in each formula (unit: Kg) is shown in Table 1.

[0021] raw material

[0022] Soybean oil

[0023] The method for preparing the feed of the present invention with the above-mentioned raw materials is: (1) pulverize the non-powdered materials in the above-mentioned raw materials; (2) fully stir all the raw materials with a mixer; (3) make the above-mentioned mixture into granules according to conventional methods The feed is the finished product.

Embodiment 2

[0025] The feed prepared with formula 3 and formula 4 of Example 1 was fed with about 850g of grass carp in the farm for 150 days. Among them, the common grass carp commercial feed was fed as the control group, and the formula 3 feed was fed with experimental group 1. The formula 3 feed was experimental group 2, with three replicates in each group, and 100 grass carps were fed in each pond. The breeding effect is shown in Table 1 to Table 4.

[0026] The formula of common grass carp commercial feed used in the control group was: soybean meal 80Kg, cotton meal 240Kg, rapeseed meal 240Kg, sub-meal 293Kg, soybean oil 20Kg, bran 100Kg, calcium dihydrogen phosphate 15Kg, choline chloride 2Kg, and pre-powder 10Kg. The preparation method of Example 1.

[0027] The above-mentioned feed was used to feed about 850g of grass carp in the experimental fishery farm of Hunan Agricultural University for 150 days. Among them, the normal grass carp commercial feed was fed as the control group, and t...

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 fish meat quality. 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 of the northeast, east, central and southern regions of China. It grows fast, produces high yields, and is loved by consumers for its good meat quality. Become the best among conventional breeding species. However, for a long time, people have believed that grass carp is a typical herbivorous fish. It is fed with green fodder, dry grass, aquatic grass and crop straw. Because these plant-based feeds have high crude fiber content and low protein and other effective nutrients, grass carp is not easy to digest and absorb after ingesting. After the excrement of grass...
