Problems solved by technology

During production, the ammoniation and alkalization of rape straw can improve its digestion and utilization in animals to a certain extent, and promote the growth of animals, but the residual alkali, such as sodium hydroxide, will affect the animals themselves and the natural environment. cause serious injury and pollution

Embodiment 1

[0014] A method for processing rapeseed straw feed that improves the utilization rate of ruminants, the steps of which are:

[0015] (1) Obtain fresh imperial bamboo grass, the cutting height is the above-ground part, 180cm long, the stems and leaves are green, and the fresh imperial bamboo grass has a moisture content of 83%;

[0016] (2) Cut the sun-dried rape stalks and the royal bamboo grass obtained in step (1) to 1 cm, and mix them evenly in a weight ratio of 3:7;

[0017] (3) For each kilogram of the mixture obtained in step (2), add 150 mg of Enterococcus lactic acid complex bacterial solution, mix well; Trichosaccharomyces; total probiotic count of Enterococcus lactic acid faecalis complex > 1.5×1010 cfu / g; Enterococcus lactic acid faecalis > 6×109 cfu / g, Bacillus > 5×109 cfu / g, Candida utilis Bacteria>4×109cfu / g;

[0018] (3) Fill the mixture obtained in step (2) into the silage pit or silage tower, compact and seal it, and open the pit after 40 days of fermentatio...

Embodiment 2

[0020] The nutritional value of rape straw before and after processing is shown in Table 1. It can be seen from the results that after being processed by this technology, the rapeseed straw becomes soft in texture, has a sour and fragrant smell, is rich in protein, and has better quality.

[0021] .

Embodiment 3

[0023] The rape stalk feed obtained in Example 1 was subjected to a rumen nylon bag test.

[0024] Test plan: Accurately weigh about 5 g of two kinds of rapeseed straw samples before processing and after processing, put them into nylon bags, and tie them to two long wires. There are 14 nylon bags on each of the two sample wires. Nylon bags were put into the abdominal sac of the rumen before morning feeding, and then two pairs of nylon bags (two parallels for each sample) were taken out after 4, 8, 16, 24, 36, 48, and 72 h, and washed with tap water until No haze. The nylon bag was baked at 65°C to constant weight, and used to analyze the nutrient content of the residue. According to the calculation model of rumen degradation parameters P=a+b(1-e-ct), the values ​​of a, b and c in the formula were calculated by the least square method. P is the real-time rumen degradation rate (%) of the measured nutrient of a certain sample at the incubation time t; a is the rapidly degradab...

Abstract

The invention discloses a production method of an oilseed rape straw feed capable of being improved in a utilization rate for ruminants. The production methods comprises the following steps: (1) cutting short sundried oilseed rape straws and fresh pennisetum hydridum by 1cm and evenly mixing the two materials in the weight ratio of 3:7; (2) adding 150mg of enterococcus faecalis compound bacterial solution to the mixture obtained in the step (1) per one kilometer, and mixing evenly; (3) putting the mixture obtained in the step (2) into a silage silo or a silage tower, compacting and sealing, and opening the silo after fermenting for 40 days, thereby obtaining the oilseed rape straw feed. The production method is simple; the produced feed is acidic, and the content of acid detergent fibers in the feed is reduced, while the crude protein proportion in the feed in increased; as a result, the nutritive value of the feed is increased, the digestibility of the feed is improved and the digestion and utilization of the feed in the bodies of animals are promoted.

Description

technical field [0001] The invention belongs to the technical field of agricultural feed processing, and in particular relates to a processing method of rape straw feed which improves the utilization rate of ruminants. Background technique [0002] China's rapeseed planting area is as high as 7277.7 thousand hectares, accounting for a quarter of the world's total. However, compared with the large-scale planting of rapeseed, the development and utilization rate of rapeseed straw is very low. In recent years, environmental pollution, deforestation, fire and traffic accidents caused by rapeseed straw burning have occurred frequently. Rapeseed straw is rich in fiber content, which is higher than that of wheat straw and corn straw. It is a good source of roughage and can be used for the production and breeding of ruminants. However, studies have shown that direct addition of canola straw to diets without treatment can significantly reduce animal feed intake, digestibility, and p...
