Problems solved by technology

At present, there are two main ways to use rapeseed for feed. The most researched at home and abroad is to use rapeseed meal as livestock animal concentrate; the second is fresh feeding (bolting period), but the feeding period is limited, and a balanced supply cannot be achieved.
At present, these two utilization methods are using rapeseed as protein feed, which does not involve the silage preservation of whole plant rapeseed, and there is no report on using rapeseed for silage as feed. How to effectively improve the utilization rate and use effect of rapeseed don't know

Embodiment 1

[0035] The experimental material is Huayouza No. 62 rapeseed, which was cut at the late flowering stage. The silage method is silage bag (70cm*130cm) silage.

[0036] Using a completely random design, two kinds of silage bacteria were added: solid bacteria S: Lactobacillus plantarum (CGMCC 1.557), Lactobacillus acidophilus (CGMCC1.12735), Lactobacillus Brucella (CGMCC1.3108), Lactobacillus casei (CGMCC 1.3206), the effective live bacteria of each bacteria is 1×10 10 CFU / gram, the enzyme activity of cellulase is 50,000 U / g; liquid bacterial agent L: Lactobacillus plantarum (CGMCC1.557), Lactobacillus acidophilus (CGMCC1.12735), Pediococcus pentosacea (CGMCC1.12961) , the effective viable bacteria of each strain is 1.5~2×10 9 CFU / mL; A total of 7 silage schemes were designed, including: (1) untreated rapeseed (control D); (2) adding bacterial agent S; (3) adding bacterial agent L; (4) adding bacterial agents S and L (SL); (5) Add bacterial agents S, L and brown sugar (SLB); (...

Embodiment 2

[0072] According to Example 1, each group was silaged for 60 days, and the ruminal degradation rate of each group of rapeseed feed treatment group is shown in Table 5. The specific operation is to select the dried and pulverized samples for 60 days, sieve through a 40-mesh grading sieve, weigh 3.0 g respectively and put them into nylon bags (10cm*5cm) made of 240-mesh nylon cloth, repeat 2 times per cow, put Put them into the rumen of fistula Holstein steers (3 heads) and digest them for 12h, 24h and 72h respectively, take them out, rinse slowly with water until clear, dry at 65°C to constant weight, and measure the contents of DM, CP, NDF and ADF respectively. As can be seen from the results, with the increase of digestion time, the degradation rates of DM, CP, NDF and ADF all increased significantly (p<0.05); silage DM, CP, NDF and ADF degradation rates were significantly different (p<0.05) in different processing modes of rapeseed in silage (p<0.05). 0.05). The DM degradat...

Embodiment 3

[0074] A method for preparing silage rape feed, comprising the following steps:

[0075] S1, mechanical mowing: mechanical harvesting of the whole plant of rapeseed, to obtain fresh samples of rapeseed;

[0076] S2. Drying: Cut it down and dry it on the spot, monitor the change of moisture content every day, and when it drops to 70% or below, it will be bundled and transported, and shredded by a mower;

[0077] S3. Adding additives: activate the solid bacterial agent S first, add 200 grams of brown sugar and 2L of water for every 25 grams of solid bacterial agent S to activate, adjust the water temperature between 30-37°C, stir evenly; spray evenly on the chopped rapeseed for activation The final solid bacterial agent S, liquid bacterial agent L and corn flour, wherein, the solid bacterial agent S includes: 4 parts of Lactobacillus plantarum, 3 parts of Lactobacillus acidophilus, 3 parts of Lactobacillus Brucella, 5 parts of Lactobacillus casei, fiber 1 part of prime enzyme; ...

Abstract

The invention provides a silage rape feed and a preparation method and application thereof, and the preparation method comprises the following steps: mechanically harvesting whole rape to obtain a rape fresh sample; airing on the spot, bundling and transporting when the moisture content is reduced to 70% or below, and chopping by a grass rolling machine; and uniformly spraying the solid microbial inoculum S, the liquid microbial inoculum L and corn flour into the chopped rape, bagging or kiln, compacting, sealing, ensiling, and opening the bag after ensiling. The preparation method disclosed by the invention can quickly reach a silage stable phase and reduce nutrient loss, is a special silage scheme suitable for the rape silage, effectively preserves the rape, is low in nutrient loss, low in content of acid detergent fibers and neutral detergent fibers, effectively increases dry matters, increases crude proteins and carbohydrates, and increases palatability. When the silage rape feed is used for feeding cows, the milk quality can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of silage feed, and in particular relates to a kind of silage rape feed, its preparation method and application. Background technique [0002] Silage refers to the compaction and sealing of fresh plant varieties, so that the stored green fodder is isolated from the outside air, resulting in internal hypoxia and anaerobic fermentation, thereby producing organic acids, which can keep the fresh silage for a long time, and can reduce the A storage technique or method in which nutrient loss is beneficial to animal digestion and absorption. Corn, peanut vines and other crop by-products can be used as silage raw materials. Silage preservation technology can preserve feed raw materials well, maintain their nutritional properties, reduce nutrient loss, and at the same time improve the palatability of raw materials. [0003] Forage rape, also known as double-low rapeseed, belongs to Brassicaceae Brassica forage gras...
