Hydrolytic swelling feed and manufacturing method thereof

Abstract

The invention discloses an hydrolyzed puffing forage and preparation method thereof. The method comprises: choosing the plants with high wood-fiber content such as straw, cereal shell, corn core, coconut cover, palm leaf, wood / bamboo scraps, bagasse, herbage rhizome and weed, performing hydrolysis and puffing treatment for destroying the encapsulation effect of lignin to hemicellulose and cellulose, degrading the hemicellulose and cellulose into small molecule soluble sugar, and continuously extruding and puffing by force. The continuous forced feeding and discharging technology realizes stable transitions between different pressures. The invention increases digestion rate greatly, can substitute part of corn and wheat bran, and can be prepared into complete feeds for different birds or animals in different growth stages by adding protein forage, salt, vitamin, mineral elements and aminating agent. The hydrolyzed puffing forage of the present invention has similar digestion rate with the conventional grain forage and sweeter taste, reduces cost greatly, alleviates the grain shortage difficulty, and is suitable for pig, cattle, sheep, chicken, duck, goose, rabbit and specially raised pets.

Description

【Technical field】 [0001] The invention relates to a feed, in particular to a wood fiber feed which has been hydrolyzed and puffed. [0002] The present invention also relates to a method for producing the above-mentioned feed. 【Background technique】 [0003] my country produces about 700 million tons of straw every year, including about 220 million tons of corn straw, 120 million tons of rice straw, 110 million tons of wheat straw, tens of millions of tons of soybean straw and cotton stalk, and nearly More than 10 million tons, more than 80% are directly burned or rotted without rational use. Lignocellulosic materials such as straw, grain husks, corncobs, coconut husks, palm leaves, wood / bamboo scraps, branches, weeds, bagasse, etc., have high lignin content in the cell wall, which tightly wraps cellulose and hemicellulose. [0004] Among them, taking straw as an example, the cellulose content is about 35-59%, which is formed by the dehydration and condensation of glucose. ...

AI Technical Summary

Problems solved by technology

[0009] 1. Not suitable for non-ruminant poultry and livestock;

[0010] 2. The preparation time and feeding cycle are long, and at least 5% to 25% of the total feed is infected with aerobic bacteria to varying degrees during the preparation and feeding process;

[0011] 3. Not suitable for young ruminants, only suitable for young and adult ruminants, such as: calves cannot be fed silage before 4 months of age

[0012] 4. Although the nutritional value and digestibility of straw in the wax ripening stage are higher than those of dry yellow straw, they are still low, and the nutritional content after silage is even lower;

This technology solves the problems of large area occupied by straw, inconvenient transportation and storage, and poor palatability. Its disadvantages are:

[0015] 1. Only suitable for large herbivores

[0016] 2. The problem of low digestibility of straw is not solved;

[0017] 3. The problem of low nutritional value of straw has not been solved

[0019] 1. The cost of complete sets of equipment is huge, the input-output ratio is low, and the return on investment is low;

[0020] 2. It is difficult to stop when starting up, and the noise pollution of blasting is large;

[0021] 3. It is difficult to clean the material after sticking to the wall and carbonized;

[0022] 4. The increase of soluble sugar content is limited, and it is not effective for monogastric animals;

[0023] 5. Intermittent instantaneous sudden change discharge, high requirements on equipment materials and great damage

[0025] 1. Only suitable for young and adult ruminants; not suitable for monogastric animals

[0026] 2. Long production cycle: about 1 week in summer, 5-7 weeks in winter in the south of the Yangtze River; 8-10 in winter in North China, and too late to use the ammoniated straw that was put into the cellar in winter in Heilongjiang

[0027] 3. It is not easy to control miscellaneous bacteria, and the failure rate is high;

[0028] 4. Concentrated release of ammonia can negatively balance nitrogen, easily cause ammonia poisoning, and increase the burden on the kidneys;

[0029] 5. The utilization rate of ammoniating agent is less than 50%; residual ammonia causes air pollution;

[0030] 6. The workload is heavy, causing great damage to the respiratory mucosa and eyes of employees;

[0031] 7. A large area of ​​open space is needed away from the crowd for ammonia release;

However, as detected by the Van Soest method, the increase in the soluble sugar content is limited
