Problems solved by technology

However, apple pomace contains a variety of anti-nutritional factors, mainly pectin and tannin. Fresh pomace can eliminate pectin after a period of natural stacking, but it is easy to be polluted by mycotoxins, stinky and black. Therefore, the apple pomace is limited. Extensive utilization of slag

Embodiment 1

[0035] A fermented feed for dairy cows and a preparation method thereof, the specific steps are as follows:

[0036] 1) Preparation of seed solution

[0037] Slant culture: under sterile conditions, Saccharomyces cerevisiae, Aspergillus niger and Bacillus subtilis were respectively inoculated in the potato slant medium, and cultured at a constant temperature of 30°C for 48 hours.

[0038] The composition of the potato slant medium is as follows: 150 g of potatoes, 10 g of glucose, 20 g of agar, 1000 ml of water, natural pH, and sterilized at 121° C. for 30 minutes.

[0039] Seed liquid culture: under aseptic conditions, wash the activated slant strains with physiological saline, inoculate them into the seed medium, and culture them in constant temperature shake flasks at 30°C and 200r / min for 48 hours to obtain brewing Yeast seed liquid, Aspergillus niger seed liquid and Bacillus subtilis seed liquid; the composition of the seed liquid culture medium: 250g of potatoes, 20g of...

Abstract

The invention relates to a fermented feed for cows and a preparation method of the fermented feed. The fermented feed is prepared from 30-40% of all cotton seeds, 15-25% of apple pomace, 5-15% of potato residues, 2-5% of ammonium sulphate and 30-40% of water, wherein the water content of the apple pomace is 50% or below, and the water content of the potato residues is 70% or below; and a seed fluid is prepared from microzymes, molds and bacillus, and the fermented feed is prepared by a microorganism solid fermentation method. The content of anti-nutritional factors in the fermented feed is low, the fermented feed is good in palatability, macromolecular protein is degraded into micromolecular peptide and amino acids, and the fermented feed contains rich nutrient components including vitamins, mineral substances and the like, and has the advantages of increasing the by-pass rumen starch rate of the cows, promoting the growth and the development of the cows, increasing milk production, improving milk quality, strengthening the immunity of the cows, reducing the usage of antibiotics, controlling environment pollution and the like.

Description

technical field [0001] The invention belongs to the field of feed preparation, and in particular relates to a fermented feed for dairy cows and a preparation method thereof. Background technique [0002] At present, my country's dairy cow production is facing many problems and tests, and the low efficiency has become an important bottleneck restricting the healthy development of my country's dairy industry. In the second half of 2014, Hebei, Shandong and other places experienced more serious milk dumping and slaughtering of cattle. The reason is that after 2008, my country's dairy farming has transformed from the original backward retail households to large-scale transformation, resulting in high "systematic" costs in the industrial chain. As a result, the cost of domestic dairy farming is higher than that of international ones, and the rise in feed costs is one of the main reasons for this performance. [0003] Therefore, finding and rationally utilizing low-cost unconventi...
