Modified sweet potato residue feed for improving laying rate of chickens and preparation method thereof

Abstract

The invention discloses a modified sweet potato residue feed for improving a laying rate of chickens and a preparation method thereof. The modified sweet potato residue feed is prepared from the following raw materials in parts by weight: 500 to 520 of sweet potato residues, 12 to 14 of rabbit meat powder, 23 to 26 of freshwater shrimp powder, 7 to 8 of citric acid, 34 to 36 of eggplant seed powder, 15 to 17 of black sesame seed powder, 42 to 45 of oat powder, 3 to 4 of green pepper juice, 3 to 4 of radish paste, 4 to 5 of potamogeton crispus, 3 to 4 of caulis polygoni multiflori, 42 to 47 of silkworm chrysalis meal, 3 to 4 of red soy sauce, 3 to 4 of barley malt sprouts, 2 to 3 of jujube flower, 32 to 34 of pea meal, 0.3 to 0.4 of EM zymophyte, 4 to 6 of carrot powder, 2 to 3 of lophatherum gracile powder, and 1 to 2 of soybean phospholipid. The modified sweet potato residue feed disclosed by the invention can improve the laying rate of chickens, increase content of vitamins and trace elements in eggs, improve egg nutrition, increase an egg volume, and prolong an egg producing period; the feed is delicious and attractant; chickens fed by the feed lay more eggs; eggs have large volumes; egg yolks and egg white have good colors; egg taste is delicious.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a modified sweet potato residue feed for improving the egg production rate of chickens and a preparation method thereof. Background technique [0002] Sweet potato residue is the residue after the sweet potato flour factory produces sweet potato flour and the sweet potato starch factory extracts sweet potato starch, accounting for about 45-60% of the fresh weight. The main components of sweet potato dregs are starch, cellulose and a small amount of protein. After fresh sweet potatoes are processed with starch, the starch content in the sweet potato dregs is still very high. Even after drying, the sweet potato dregs still contain 36-58% starch. A food processing enterprise with an annual output of 3 000 t of sweet potato starch can produce about 4 000 t of wet residue, but only a small part of such a huge output is used as feed raw materials, and the rest are discarded a...

Problems solved by technology

[0003] The article "Research on the Value-Adding Effect of Solid-State Fermented Sweet Potato Dregs" introduces the scheme of using lactic acid bacteria, bacillus, yeast and mold to ferment sweet potato dregs. The sweet potato dregs are not further modulated and processed, so the palatability of the final fermented product is not very ideal.
