Embodiment 1

[0042] In this example, the inoculation ratio of Lactobacillus acidophilus was investigated, and the fermentation experiment was carried out by inserting into the culture medium of sweet potato residue and sweet potato flour processing wastewater according to different (W / W) inoculation amounts, and the fermentation time was 24-72h. The inoculation ratios were 2%, 4%, 5%, 6%, 8%, and 10%, respectively, and the total number of colonies in the fermentation product was measured. The results are shown in Table 1. Known from Table 1, the optimum seed solution ratio is 5%.

Embodiment 2

[0046] In the present invention, the fermentation time is investigated, and the liquid seed solution with an inoculation ratio of 5% of Lactobacillus acidophilus is inserted into the liquid medium of sweet potato flour processing wastewater and sweet potato dregs, and the fermentation temperature is 37°C, as shown in Table 2 below.

Embodiment 3

[0050] The fermented liquid was spray-dried by adding different auxiliary materials. The amount of auxiliary materials added was 30%, and there were obvious differences in the number of colonies, as shown in Table 3 below.

Abstract

The invention discloses a feed probiotic additive for ruminants and application of the feed probiotic additive. The additive is directly used as the additive after lactobacillus acidophilus is fermented in a sweet potato residue and sweet potato powder wastewater fermentation culture medium and fermentation liquor is dried. The produced feed probiotic agent is used for carrying out a cattle feeding test, and the viable count of lactobacillus acidophilus in the feed probiotic additive reaches 8.9 * 10 < 9 > cfu / g. Compared with other feed probiotics, the method disclosed by the invention has the advantages of low raw material cost, high production efficiency, convenience in use, short production cycle, low energy consumption and the like, and can be used for feeding calves, so that the food digestibility of the calves is improved, the intestinal absorption of livestock and poultry is facilitated, the intestinal environment of the livestock and poultry is improved, the animal immunity is enhanced, and the obvious effect of promoting animal growth is achieved; meanwhile, production wastes such as the sweet potato residues and the sweet potato powder processing wastewater are turned into wealth, so that the recycling of waste resources is realized.

Description

technical field [0001] The invention belongs to the technical field of preparation of feed probiotics, in particular to a feed probiotic additive for ruminants and an application thereof. Background technique [0002] Probiotics are mainly organisms that can maintain the balance of intestinal microorganisms. As beneficial microorganisms, they widely exist in nature. Probiotics replace antibiotics as veterinary drugs and feed additives, and are widely valued and applied. They improve the intestinal microbial balance of host animals. Beneficially affecting host animals, it can be used to replace feeding antibiotics, enhance immunity, promote animal health and growth, improve feeding efficiency, reduce feeding costs, use it instead of feeding antibiotics, reduce antibiotic residues in animal products, and inhibit drug resistance pathogenic bacteria. Sweet potato flour is an important ingredient in the common diet. During the production and processing process, a large amount of...
