Abstract

The invention discloses mixed fermented feed for dairy cattle in the dry period and a preparation method thereof. The mixed fermented feed is prepared from following raw materials by weight percent: 35-45% of corn straws, 30-40% of potato starch residues, 0.4-0.6% of sodium bicarbonate, 8-15% of vinegar residues, 1-3% of calcium bicarbonate, 0.2-0.5% of table salt, 5-15% of perillaseed cake residues, 0.1-0.2% of magnesium oxide and 0.5-0.8% of a premix. The raw materials are weighed according to the formula and a process of roughly rolling, finely rolling, and bundling and wrapping is adopted so as to generate a great quantity of lactic acid bacteria; an anaerobic environment is formed in a bag to sufficiently ferment so as to prepare the mixed fermented feed for the dairy cattle in the dry period, which has the guarantee period being more than 24 months. The content of rough fibers of the fermented feed is more than or equal to 40% and the content of rough content of the fermented feed is less than or equal to 6.51%. The mixed fermented feed is particularly suitable for feeding the dairy cattle in the dry period.

Description

technical field [0001] The invention belongs to the technical field of livestock feed processing, and in particular relates to a mixed fermented feed for dairy cows in dry milk period and a preparation method thereof. Background technique [0002] Fermented feed means that under artificial control conditions, microorganisms decompose or transform anti-nutritional factors in plant, animal and mineral substances through their own metabolic activities, and produce higher nutrients that can be digested and absorbed by livestock. And non-toxic feed raw materials. In recent years, due to the rapid development of the animal husbandry industry, the contradiction between people saving food and food has become increasingly prominent. In order to solve this problem, the scientific and technological circles and industrial circles all over the world are looking for and researching new feed resources, and fermented feed has begun to receive attention. [0003] With the continuous improve...
