Problems solved by technology

The most widely used utilization of the by-products of citrus peel processing is to use citrus peel residues directly as feed and add them to animal diets to reduce feed costs and alleviate feed shortages. However, this extensive use method cannot meet the needs of modern colleges and universities. The needs of the rapid development of animal husbandry, not to mention the inability to maximize the nutritional value of citrus pomace

Embodiment 1

[0015] (1) The first step, the configuration of the first-stage fermentation medium: the weight percentage of each raw material in the first-stage fermentation medium is: citrus peel 95%, rapeseed meal 3%, urea 0.1%, ammonium nitrate 0.5% , calcium carbonate 0.4%, potassium dihydrogen phosphate 0.5%, magnesium chloride 0.5%;

[0016] (2) The second step, the first-stage fermentation: add a starter consisting of Aspergillus oryzae and Neurospora crassa to the first-stage fermentation medium, so that the total number of viable bacteria of Aspergillus oryzae and Neurospora crassa in the medium is 2 ×10 8 cfu / (kg medium), fermented at 25°C for 2 days;

[0017] (3) The third step, the second-stage fermentation: Add rapeseed meal and soybean meal to the fermented medium obtained in the second step, and the rapeseed meal and soybean meal are respectively 5% of the total weight of the fermented medium obtained in the second step. %% was added to obtain the second-stage fermentatio...

Embodiment 2

[0020] (1) The first step, the configuration of the first-stage fermentation medium: take a certain amount of citrus peel, rapeseed meal, urea, ammonium nitrate, calcium carbonate, potassium dihydrogen phosphate and magnesium chloride, and mix the above raw materials evenly. The percentage by weight of each raw material in the fermentation medium of the first stage is: citrus peel residue 91.5%, rapeseed meal 4%, urea 0.3%, ammonium nitrate 1%, calcium carbonate 2%, potassium dihydrogen phosphate 1%, magnesium chloride 0.2%.

[0021] (2) The second step, the first-stage fermentation: add a starter consisting of Aspergillus oryzae and Neurospora crassa to the first-stage fermentation medium, so that the total number of viable bacteria of Aspergillus oryzae and Neurospora crassa in the medium is 2 ×10 9 cfu / (kg medium), fermented at 28°C for 2 days.

Abstract

The invention relates to a citrus reticulata peel residue feed preparation method, wherein the main raw material is citrus reticulata peel residue, and multi-stage fermentation is performed to prepare the feed. According to the present invention, the prepared feed can basically meet the protein requirement of animal feeding, and contains a certain amount of oligosaccharides; after the prepared citrus reticulata peel residue feed is added to feeds, the palatability is good, the animal feed intake is increased, and the health effects of animal intestinal tract health improving and animal immunity improving are achieved; and the equipment for production is less, the operation process is simple, the use effect is good, the citrus reticulata peel residue utilization problem can be fundamentally solved, the preparation method is one of the optimal schemes for the development and utilization of the citrus reticulata peel residue, the comprehensive utilization of the citrus reticulata peel residue is achieved, and the significant ecological and social benefits are provided.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for preparing citrus peel feed. Background technique [0002] The citrus peel is rich in nutrients, and yeast can be added to ferment to produce alcohol, citric acid, etc., and it can also be inoculated with Barley's yeast to produce pyruvate; or inoculated with Acetobacter to ferment and produce V B12 Wait. Citrus peels can also be used in the production of candied fruit, preserved fruit, and jam products. The processing of sleeve peels in Meizhou and Chaoshan areas of Guangdong has a long history and has formed a certain scale. [0003] Every year, the United States, Brazil and other major citrus producing countries dry more than 40% of the citrus peels and use them for the production of pellet feed, and then feed them to cattle and sheep. Tangerine peel can also be fermented by the mixed bacteria of Aspergillus niger Ⅱ and Candida utilis Ⅰ. The nutritional value of the feed obta...
