Problems solved by technology

[0004] The traditional method to improve the quality of eggshells is to increase the amount of calcium, phosphorus, and vitamin D in the feed, combined with phytase technology. However, the disadvantages of this method lie in the following points: (1) The cost of the traditional method is relatively high ; (2) The absorption of calcium and phosphorus of laying

Embodiment 1

[0030] A special fermented feed for laying hens that can improve the quality of eggshells is prepared by uniformly mixing a fermented base material with a fermented bacterial liquid, and alternately carrying out aerobic and anaerobic fermenting until the pH value is 4.2-.

[0031] The fermentation base material includes 48 parts by weight of corn, 22 parts by weight of soybean meal, 10 parts by weight of wheat bran, 8 parts by weight of stone powder, 2 parts by weight of Calcium dihydrogen phosphate and parts by weight are 0.15 parts of amylase;

[0032] The fermentation liquid is multiplied by composite fermentation strains including Bacillus subtilis, Lactobacillus acidophilus, Pediococcus pentosaceae, and Saccharomyces cerevisiae, and the weight ratio of the composite fermentation strains to the fermentation base material is 0.5 : 1000.

[0033] The preparation method of the special fermented feed for laying hens that can improve the quality of eggshells comprises the foll...

Abstract

The present invention discloses a special fermented feed for laying hens capable of improving quality of eggshells and a preparation method thereof. The special fermented feed for the laying hens is prepared by uniformly mixing fermentation base materials and fermentation micro-organism liquid; the mixture is alternately subjected to aerobic fermentation and anaerobic fermentation to a pH value of4.2-4.7; the fermentation base materials comprise corns, wheat bran, soybean meal, stone powder, calcium dihydrogen phosphate and amylase; and the fermentation micro-organism liquid is prepared by expanding propagation of compound fermentation micro-organism strains of bacillus subtilis, lactobacillus acidophilus, pediococcus pentosaceus and saccharomyces cerevisiae. A nutrient-optimized microbial fermentation engineering technology is used to enable calcium and phosphorus required by the laying hens to participate in the fermentation, improves structural properties and material properties ofthe eggshells of the commercial laying hens, thus improves the eggshell quality and reduces an egg breaking rate. The bio-fermented feed ensures an egg production rate, prolongs an egg laying period,and has relatively high practical value for breeding enterprises.

Description

technical field [0001] The invention relates to a biologically fermented feed, in particular to a special fermented feed for laying hens capable of improving eggshell quality and a preparation method thereof, belonging to the technical field of feed. Background technique [0002] The biological feed industry is the main direction of the "13th Five-Year Plan" to promote the transformation and upgrading of the feed industry, and it is also an important "window opportunity period" for the development of the biological feed industry. Bio-fermented feed is an important part of bio-feed. my country's bio-feed is still in its infancy and has not yet entered the track of industrialization and standardization. [0003] my country is a big laying hen breeding country in the world. In recent years, commercial laying hens have accounted for 40% to 45% of the world's stocks, and the annual output of eggs is nearly 20 million tons. my country's laying hen farming has gradually developed f...
