Problems solved by technology

At present, corn stalk feed fermented with commercially available corn stalk feed starter has poor palatability and can only be fed to ruminants such as cattle and sheep, and cannot be used as feed for monogastric animals such as chickens and pigs, so the scope of use is greatly limited

Embodiment Construction

[0029] Weigh 10g of casein peptone, 5g of beef extract, 4g of yeast powder, 20g of glucose, 2g of triammonium citrate, 5g of sodium acetate, 1g of Tween 80, K 2 HPO 4 2g, MgSO 4 .7H 2 O 0.2g, MnSO 4 .H 2 O 0.05g, add water to dilute to 1L, adjust the pH to 6.8, insert Lactobacillus plantarum from the slope, and culture it statically at 37°C for 19 hours to obtain the Lactobacillus plantarum culture solution. Centrifuge the Lactobacillus plantarum culture solution at 4000 rpm for 20 minutes to obtain the Lactobacillus plantarum sludge.

[0030] Weigh 50 g of soybean protein peptide, 30 g of glucose, 30 g of yeast extract, K 2 HPO 4 1g, MgSO 4 .7H 2 O 0.5g, add water to dilute to 1L, adjust the pH to 6.5, insert Leuconostoc enteritidis from the slope, and culture it statically at 30°C for 19 hours to obtain the Leuconostoc enteritidis culture solution. The Leuconostoc enterolis culture solution was centrifuged at 4000 rpm for 20 minutes to obtain the Leuconostoc enter...

Abstract

The invention relates to a preparation method of a corn straw feed leavening agent, and belongs to the technical field of feed processing. The preparation method comprises the following steps: respectively preparing culture solutions of lactobacillus plantarum, leuconostoc mesenteroides, bacillus subtilis, bacillus licheniformis, aroma-producing yeast and baker's yeast, centrifuging to obtain bacterial sludge of the strains, adding the bacterial sludge into sterile water, and uniformly stirring to obtain the finished product. The corn straw fermented feed prepared from the feed leavening agentis good in palatability and wide in application range, ruminants such as cattle and sheep can be fed, and monogastric animals such as chickens and pigs can also be fed.

Description

technical field [0001] The invention relates to a preparation method of a corn stalk feed starter, belonging to the technical field of feed processing. Background technique [0002] The incineration of corn stalks not only brings huge pollution to the environment, but also causes a waste of resources. Corn stalks are fermented by microorganisms to make feed that can be directly fed to pigs, chickens and other livestock and poultry, which improves the softness and palatability of the straw, and improves the safety. It not only solves the problem of "outlet" for straw, but also reduces environmental pollution It also reduces the cost of breeding, improves the quality of meat and eggs, and solves the problem of human and livestock competition for food. It is currently the most popular and promising straw feed technology. At present, corn stalk feed fermented with commercially available corn stalk feed starter has poor palatability and can only be fed to ruminants such as cattl...
