Problems solved by technology

[0006] However, the utilization rate of inorganic zinc is not high due to its low biological potency, while the application of organic zinc with high biological potency is limited due to its high cost.

Embodiment 1

[0020] 1 test material

[0021] The cultivation medium of Pleurotus eryngii uses hybrid pennisetum hay with low phytic acid content instead of bagasse. 9 parts, 1.2 parts of lime, 1.8 parts of light calcium; the fungus chaff of picking 3 crops of fruit bodies is selected as raw material, and the production process of the Pleurotus eryngii fungus chaff fermentation material is 50 parts of Pleurotus eryngii fungus chaff, 27 parts of fine system bran, barley 18 parts, 5 parts of water, fine bran is notoginseng bran, particle size 0.5-1.0mm. After the Lactobacillus inoculum is activated, it is evenly sprayed on the raw material at a ratio of 0.1% (w / w), mixed evenly, put into a bag and sealed for fermentation. The Lactobacillus inoculum is purchased from Guangzhou Changhe Biotechnology Co., Ltd. Bao II type. After storage at room temperature (about 25°C) for 21 days, the zinc content of the fermented Pleurotus eryngii fungus chaff is 20.5 mg kg -1 . Changes in mineral element ...

Embodiment 2

[0038] Replace the Pleurotus eryngii culture substrate formula in Example 1 with the Pleurotus eryngii culture substrate formula in Table 3, and then each formula selects the fungus chaff of picking 1 crop, 2 crops, and 3 crops of fruiting bodies as raw materials, and obtains 15 Process, all the other are with embodiment 1.

[0039] Table 3 Example 2 Each group of Pleurotus eryngii culture substrate formula unit: %

[0040]

[0041] figure 2 Phytic acid content of Pleurotus eryngii obtained from 15 treatments, from figure 2 It can be seen from the figure that taking the fungus chaff of the first batch of Pleurotus eryngii as an example, compared with the control group, the content of phytic acid contained in the formula 3 and 100% of the formula 3 and 100% of the bagasse replacement ratio in the control group was reduced. 11.87% and 19.29%; in addition, it can be seen that the phytic acid content in Pleurotus eryngii mushroom chaff is negatively correlated with the numb...

Abstract

The invention discloses a fermented mushroom bran mixed feed for increasing the zinc content in a ruminant livestock meat product. The fermented mushroom bran mixed feed comprises the following components in parts by mass of 17-34 parts of a pleurotus eryngii mushroom bran fermented material, 27-42 parts of peanut vines, 5-20 parts of corn, 7-9 parts of soybean meal, 6-9 parts of cottonseed meal, 0.5-0.7 part of carboxymethyl chitosan, 0.5-1.0 part of oyster shell powder and 5 parts of a premix. According to the mixed feed, the pleurotus eryngii mushroom bran is used as feed, and sustainable development of ecological agriculture and animal husbandry is promoted. In addition, the content of mineral elements such as Ca, Cu and Fe in the pleurotus eryngii mushroom bran can be reduced after the pleurotus eryngii mushroom bran is fermented, the content of phytic acid in the pleurotus eryngii mushroom bran is reduced by preparing a pleurotus eryngii culture medium with pennisetum alopecuroides and selecting the picking stubble number, and therefore the biological utilization rate of Zn is delayed or reduced in the modes that the mineral elements, phytic acid and Zn form chelates, competitive inhibition and the like. Meanwhile, the carboxymethyl chitosan can form coordination with Zn <2+>, so that the absorption and utilization rate of the cattle and sheep enteric cavities to Zn is improved.

Description

technical field [0001] The invention relates to the technical field of animal husbandry feed processing, in particular to a fermented bacteria chaff mixed feed for increasing zinc content in ruminant livestock meat products. Background technique [0002] Zinc (Zn) is one of the essential trace elements for the human body. It can be used as an essential component or activator of various enzymes in animals to participate in various metabolic activities in the body. It is called "the element of life". Zn deficiency can lead to stunted growth, anorexia, decreased immunity and fecundity. In view of the importance of Zn to the health of the human body, people must ingest an appropriate amount of Zn from their daily diet in order to ensure the normal physiological metabolism of the body and maintain immunity. Eating beef, sheep and other ruminant livestock meat products for zinc supplementation has a long history in China. According to the results of food nutrition query, the aver...
