Nutrition enhanced feed for parent carassius auratus in reproduction period

Abstract

The present invention discloses a nutrition enhanced feed for parent carassius auratus in a reproduction period. The feed is prepared from the following raw materials in parts by weight: 125-130 parts of expanded corn meal, 70-75 parts of peanut meal, 65-70 parts of bone meal, 15-17 parts of chicken feathers, 1.1-1.3 parts of edible salt, 40-42 parts of wheat germs, 55-57 parts of oyster meat, 20-22 parts of oyster shells, 0.04-0.06 part of astaxanthin, 0.13-0.15 part of zeaxanthin, 3-5 parts of palm oil, 1.1-1.3 parts of spinach extracts, 0.6-0.8 part of mulberry leaf extracts, 1.2-1.4 parts of cactus extracts, 0.23-0.25 part of compound vitamin, 2.2-2.4 parts of garlic essential oil and 0.14-0.16 part of sodium lactate. The feed is scientific and reasonable in formula, and comprehensive and rich in nutrition, and various nutritional components cooperate with each other, so that the feed effectively enhances the reproductive performance of the parent carassius auratus, is good in palatability and easy to digest, greatly improves the feeding amount and absorbing and transforming effects of the carassius auratus, and effectively improves the meat quality.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a nutrient-enhanced feed for crucian carp broodstock breeding period. Background technique [0002] Crucian carp is streamlined, tall and flat on the sides, the front half is curved, the back contour is raised, the tail peduncle is wide; the abdomen is round, without fleshy ribs; the head is short, the snout is blunt; there is no need; the hypopharyngeal teeth are lined, flat, the scales are large; the lateral line Slightly curved; long dorsal fin, relatively straight outer edge; gill rakers are slender, needle-shaped, closely arranged, the number of gill rakers is 100-200; the third hard spines of dorsal and anal fins are stronger, with serrations on the rear edge; the end of pectoral fin can reach The starting point of the pelvic fin; the deep forked body of the caudal fin is silver-gray and slightly yellowish on the back, silvery-white and slightly yellowish on the abdomen...

AI Technical Summary

Problems solved by technology

[0004] The digestive tract of crucian carp is short, the feed stays in the digestive tract for a limited time, and the nutrients in the feed are difficult to be completely absorbed in a short period of time, which not only leads to low reproductive performance of broodstock, poor quality of fertilized eggs, low survival rate of newly hatched fry, and no The absorbed food residues are excreted from the body, causing a large number of microorganisms to grow, polluting the environment, and easily causing diseases
