Modified sweet potato residue feed for improving utilization ratio of nutrition for chicken and preparation method thereof

Abstract

The invention discloses a modified sweet potato residue feed for improving the utilization ratio of nutrition for a chicken and a preparation method of the modified sweet potato residue feed for improving the utilization ratio of the nutrition for the chicken. The modified sweet potato residue feed is prepared from the following raw materials in parts by weight: 450 to 470 parts of sweet potato residues, 42 to 45 parts of flax meal, 24 to 26 parts of corn alcohol lees, 7 to 8 parts of citric acid, 37 to 42 parts of moringa seed powder, 32 to 38 parts of black bean flour, 17 to 19 parts of pawpaw powder, 3 to 4 parts of safflower seed oil, 7 to 9 parts of cuttlefish meat powder, 4 to 5 parts of Chinese clovershrub root, 2 to 3 parts of Chinese wolfberry flower, 42 to 45 parts of black glutinous rice flour, 2 to 3 parts of coconut milk, 3 to 4 parts of lotus root starch, 1 to 2 parts of chicken blood meal, 35 to 38 parts of whole wheat flour, 0.3 to 0.4 part of EM (Effective Microorganisms) zymophyte, 5 to 6 parts of yellow peach powder, 1 to 2 parts of jujube kernel powder, and 4 to 6 parts of puffing bone meal. The modified sweet potato residue feed disclosed by the invention can improve the utilization rate of the nutrition for the chicken, the weight gain rate and the fattening rate of the chicken, and the egg laying rate of the chicken, increase the egg volume and the egg nutrition, promote the growth and development of the chicken and shorten the growth cycle of the chicken, so that the chicken grows fast and lays more eggs and the material consumption is less.

Description

[0001] technical field [0002] The invention relates to the technical field of poultry breeding, in particular to a modified sweet potato dregs feed for improving the nutrient utilization rate of chickens and a preparation method thereof. Background technique [0003] 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 ar...

Problems solved by technology

[0004] 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.
