Abstract

The invention discloses a low-concentrate type fermented total mixed ration (TMR) for dairy cows and a preparation method thereof. The TMR is prepared by the following steps of: (1) mixing the following materials in part by mass to obtain a mixture: 15 to 20 parts of straw, 4 to 8 parts of fodder grass, 6 to 12 parts of protein feed, 25 to 30 parts of energy feed, 3 to 6 parts of minerals and molasses, 40 to 45 parts of food processing by-products and 0.5 to 1 part of premix compound of trace elements and vitamins; (2) adjusting the moisture content of the mixture of the step (1) to be between 40 and 50 percent; and (3) sealing and fermenting the mixture of the step (2) for more than 14 days to obtain the ration for the dairy cows. The TMR of the invention has the following advantages of: low cost; complete nutrition and homogeneous components to avoid animal picky eaters and significantly improve the production performance of animals; and high aerobic stability. The low-concentrate type fermented total mixed ration for the dairy cows opens up a new technique and an effective way for efficient utilization of the resources of the straw and the food processing by-products, and has important practicability and application promotion values.

Description

technical field

[0001] The invention belongs to the field of livestock feed processing, and in particular relates to a low-concentrate fermented total mixed ration (TMR, Total Mixed Rations) for dairy cows and a preparation method thereof. Background technique

[0002] According to statistics, my country's annual output of crop straw is about 700 million tons, accounting for about 30% of the world's total annual output of straw, which is a huge potential feed resource for the development of herbivorous livestock. However, crop stalks are rough and hard, and their nutritional value is not high. If they are directly used as feed for ruminants, they will have low digestibility and poor palatability, making it difficult to effectively use them. At present, the utilization rate of straw in my country is only 33%, and the utilization rate of the part after technical treatment is less than 3%.

[0003] Food processing by-products generally have high moisture content, are not resis...
