Embodiment 1

[0020] Postpartum broodstock feed for perch is composed of the following raw materials in parts by weight: 32 parts of Peruvian super fish meal, 6 parts of concentrated soybean protein, 25 parts of soybean meal, 23 parts of ordinary flour, 1.5 parts of soybean oil, 2 parts of soybean lecithin, and 2 parts of high-quality fish oil , 1 part of calcium dihydrogen phosphate, 0.15 part of d1-a tocopheryl acetate, 0.3 part of freshwater fish vitamin, 0.8 part of compound mineral salt, 0.2 part of yeast active peptide, 0.1 part of astaxanthin, 0.3 part of choline, betaine 0.3 parts, 0.04 parts of ethoxyquinoline, 0.1 parts of antifungal agent, 0.2 parts of immune polysaccharide, 0.15 parts of vitamin C phosphate, and 3.16 parts of bentonite.

Embodiment 2

[0022] Postpartum broodstock feed for perch is composed of the following raw materials in parts by weight: 30 parts of Peruvian super fish meal, 10 parts of soybean protein concentrate, 28 parts of soybean meal, 22 parts of plain flour, 1 part of soybean oil, 3 parts of soybean lecithin, 3 parts of high-quality fish oil, 1.5 parts of calcium dihydrogen phosphate, 0.2 parts of seawater fish vitamins, 1 part of compound mineral salts, 0.1 parts of yeast active peptides, 0.3 parts of astaxanthin, 0.1 parts of choline, 0.5 parts of betaine, 0.05 parts of ethoxyquinoline, 0.2 part of antifungal agent, 0.1 part of immune polysaccharide, 0.2 part of vitamin C phosphate, 3 parts of bentonite.

Embodiment 3

[0024] Postpartum broodstock feed for perch is composed of the following raw materials in parts by weight: 33 parts of Peruvian super fish meal, 8 parts of soybean protein concentrate, 27 parts of soybean meal, 25 parts of plain flour, 3 parts of soybean oil, 1 part of soybean lecithin, 1 part of high-quality fish oil, 0.5 part of calcium dihydrogen phosphate, 0.2 part of d1-a tocopheryl acetate, 0.5 part of seawater fish vitamin, 0.5 part of compound mineral salt, 0.3 part of yeast active peptide, 0.2 part of astaxanthin, 0.5 part of choline, 0.1 part of betaine 0.1 part of antifungal agent, 0.3 part of immune polysaccharide, 4 parts of bentonite.

[0025] By feeding the postpartum broodstock with the compound feed processed by the above formula, compared with the traditional feed, the postpartum recovery time of the broodstock is more than 2 weeks earlier; the reproductive rate in the second year is increased by more than 11%, and the amount of eggs laid is significantly incr...

Abstract

The invention relates to a feed for fish, and in particular relates to a feed for postpartum parent percocypris pingi. The feed is prepared from the following raw materials in parts by weight: 30-33 parts of Peru super fish meal, 8-10 parts of soy protein concentrate, 25-28 parts of bean pulp, 22-25 parts of common flour, 1-3 parts of soybean oil, 1-3 parts of soybean lecithin, 1-3 parts of high-quality fish oil, 0.5-1.5 parts of calcium dihydrogen phosphate, 0.2-0.5 part of ocean fish vitamins, 0.5-1 part of complex mineral salt, 0.1-0.3 part of yeast active peptide, 0.1-0.3 part of astaxanthin, 0.1-0.5 part of choline, 0.1-0.5 part of betaine, 0.1-0.2 part of a mould inhibitor, 0.1-0.3 part of immunopolysaccharide and 3-4 parts of bentonite. After the feed for the postpartum parent percocypris pingi is used, the demand of the postpartum parent percocypris pingi for the nutrition can be met, the postpartum recovery speed of the parent percocypris pingi can be accelerated, and the reproductive capacity of the parent percocypris pingi can be improved.

Description

technical field [0001] The invention relates to a fish feed, in particular to a feed for broodstock after giving birth to perch. Background technique [0002] Perch is also called Jinsha perch, big flower fish. Pointy mouth, forward protruding jaw, slender figure covered with tiny scales. Bass carps are mainly distributed in the upper reaches of the Yangtze River and the Nanpan River water system. They live in the middle and upper layers of rivers. They are ferocious carnivorous fish that feed mainly on animal feed. In rivers, they mainly eat other wild fish. The common Jinsha perch weighs 1 to 5 kilograms, and the heaviest can reach more than 20 kilograms. Generally, as it grows older, its body length growth rate will gradually slow down. This kind of fish is relatively rare and was once on the verge of extinction. Now wild domestication has achieved staged success, and it can be cultivated artificially on a large scale. Moreover, its fresh and tender meat is deeply love...
