Embodiment 1

[0015] Harvest Chinese cabbage tail vegetables in time, its water content is 94%, utilize shredder to cut short to 1-3 centimetre. The chopped Chinese cabbage tails and wheat bran were uniformly mixed in proportion, the water content of wheat bran was 11%, and the mixing ratios of Chinese cabbage tails and wheat bran were 500:0 (control group), 383:117 (treatment group 1 ), 353:147 (treatment group 2) and 323:177 (treatment group 3). Put the fermentation raw materials into an anaerobic fermentation bag with a one-way ventilation valve, compact it, and use a vacuum packaging machine to exhaust the remaining air in the anaerobic fermentation bag. The anaerobic fermentation bag is sealed with a heat sealer, and placed in a dark place for anaerobic fermentation at a room temperature of 20°C. After 60 days of fermentation, Chinese cabbage tail vegetable feed can be obtained.

Embodiment 2

[0017] The preparation method of this example is the same as that of Example 1, except that the temperature of anaerobic fermentation is 25°, and the fermentation is 30 days.

[0018] apply effects

[0019] It can be seen from Table 1 that the treatment group reduced the formation of exudate and the loss of soluble carbohydrates. The treatment group also showed that in addition to meeting the pH value of the excellent anaerobic fermentation feed, it also increased the content of acetic acid, propionic acid, and amino acid nitrogen, and reduced the formation of ammoniacal nitrogen, which proves that the feed produced by this method has excellent fermentation quality and reduced protein degradation. In addition, the treatment group also increased the number of lactic acid bacteria and reduced the number of enterobacteria and yeast, indicating that the Chinese cabbage tail vegetable feed produced by the method of the invention has a certain probiotic effect, and reduces the load...

Abstract

The invention provides a method for turning Brassica pekinensis (Lour.) Rupr. residues into feed by using by-products in the powder production industry. The method comprises the following steps of cutting the Brassica pekinensis (Lour.) Rupr. residues into small pieces of 1-3cm, uniformly mixing the small pieces with wheat bran according to a mass ratio of (323-383): (117-177), reducing the moisture, and performing anaerobic fermentation at a proper temperature to obtain the Brassica pekinensis (Lour.) Rupr. residue feed. According to the method, the yield of percolate in a fermentation process can be effectively reduced, the content of short-chain fatty acid, the content of soluble sugar, the number of lactic acid bacteria and the content of free amino acid can be increased, the number of enteric bacilli, the number of saccharomycetes, the content of ammoniacal nitrogen and the content of cellulose can be reduced, the Brassica pekinensis (Lour.) Rupr. residues and the by-products in the powder production industry can be quickly subjected to bioconversion, digestibility is improved, and the influence of weather and sites is avoided. In conclusion, the method disclosed by the invention has great application potential.

Description

technical field [0001] The invention belongs to the field of unconventional feed resource processing, and in particular relates to a method for turning Chinese cabbage tail vegetables into feed by utilizing by-products of milling industry. Background technique [0002] With the excessive increase of population, the demand for livestock products will inevitably increase. However, the lack of feed ingredients in China severely limits the development of animal husbandry. Currently, the loss of continental biodiversity has made it increasingly difficult to increase feed ingredients by expanding arable land. This has also prompted researchers to develop a sustainable feed resource, thereby alleviating the shortage of feed resources in China. [0003] Chinese cabbage is a kind of vegetable food that Chinese people like most. In 2017, the output of Chinese cabbage reached more than 110 million tons. However, due to mechanical damage caused during handling or transportation and ...
