Preparation method of seed pumpkin leaf feed

Abstract

The invention discloses a preparation method of a seed pumpkin leaf feed. The preparation method comprises the following steps: cutting seed pumpkin leaves to 1-3 cm in length, and sequentially spraying formic acid and molasses on the surfaces of the seed pumpkin leaves, wherein the ratio of the volume of the finally used formic acid to the mass of the seed pumpkin leaves is 1-2 mL / kg, and the ratio of the mass of the finally used molasses to the mass of the seed pumpkin leaves is 20 g / kg; and then carrying out anaerobic fermentation on the seed pumpkin leaves. By using the method disclosed by the invention, the pH value of the seed pumpkin leaf feed is reduced, the contents of lactic acid and acetic acid are increased, the content of butyric acid is reduced, the content of soluble sugar is increased, and the dry matter loss and the ammoniacal nitrogen content are reduced; and the crude protein content and the peptide nitrogen ratio in the seed pumpkin leaf feed are increased, the fiber content is reduced, the fermentation quality of the seed pumpkin leaf feed is improved, the nutrient loss is reduced, the nutritional value is increased, and the seed pumpkin leaf feed has great application potential.

Description

technical field [0001] The invention belongs to the technical field of non-grain feed processing, and specifically discloses a manufacturing method of pumpkin leaf feed for seeds. Background technique [0002] Seed pumpkin is a general term for pumpkins whose seeds are the main edible organs or processing objects. In China, the planting area of ​​pumpkin for seeds is about 350,000 hectares, and the annual seed production exceeds 150,000 tons. However, the yield of squash waste for seed is 49 times that of seed, and about 90 percent of this waste is usually discarded in the field. Among the wastes of seed pumpkins, the yield of leaves is huge, and leaves are rich in nutrients such as protein, soluble carbohydrates and dietary fiber. Since pumpkin leaves for seeds have a high moisture content and are rich in substrates for microbial growth, if they are discarded at will, bacteria can easily breed and cause corruption, which will endanger environmental safety and human and an...

AI Technical Summary

Problems solved by technology

Because pumpkin leaves for seeds have a high water content and are rich in substrates for microbial growth, if they are discarded at will, it is easy to breed bacteria and cause spoilage, which endangers environmental safety and human and animal health

[0003] At present, the protein content in pumpkin leaves for seeds is relatively high, resulting in strong buffering capacity, which makes it difficult for natural anaerobic fermentation to reduce the pH value to an appropriate range, thus resulting in the fermentation quality and poor quality of the obtained pumpkin leaf fermented feed for seeds The nutritional value is poor, and the energy loss is serious during the fermentation process, and it is easy to produce toxic and harmful substances and produce unpleasant odors, and the palatability is poor
