Problems solved by technology

However, the direct use of straw as feed has the following problems: First, the texture is rough and hard, poor palatability, low feed intake, and long residence time in the digestive tract, which affects the feed intake of livestock
Second, the feed value is low
Third, nitrogen content and low effective energy
Fourth, the straw has a small bulk density and a large volume, only 20-30kg per cubic meter, which cannot be transported and stored as a commodity, and is not convenient for circulation
Fifth, the existing straw treatment technology is single, and technologies such as alkalization, ammonification, and biological fermentation have not been properly assembled and matched, and the treatment effect has not yet been optimized, which cannot meet the needs of intensive aquaculture.
Sixth, there is no reasonable feed preparation for regional nutritional deficiencies, and straw is still used as roughage for simple processing or direct feeding, which is not suitable for large-scale industrial production
Main reasons: (1) The content of crude protein in the produced straw feed is low
(2) The pilot-scale fermentation technology is not perfect and the scale is small, so it is urgent to carry out scale-up experimental research
(3) It is only suitable for fresh straw, and the effect of dry yellow straw is poor, which cannot meet the processing requirements of most straws.

Abstract

The production process of composite biochemical granulated feed includes the following steps: sorting material; making filament; crushing; ammonating, alkalizing and salting; enzyme processing and biological fermentation; air drying; mixing dried stalk powder in 2-48 wt%, industrial side product in 10-30 wt%, fine material in 40-60 wt%, pre-mixed material in 0.5-3 wt% and bentonite 1.5-5 wt%; and granulating the mixture to form the composite biochemical granulated feed for ox and sheep. The present invention produces the composite biochemical granulated feed by means of the comprehensive technological process of biology, chemistry, thermodynamics, mechanics, etc to raise the feed value.

Description

technical field [0001] The invention relates to a production method of a composite pellet feed, in particular to a production method of a composite biochemical straw pellet feed. Background technique [0002] Straw is the main by-product of planting industry, with low price and huge storage. However, the direct use of straw as feed has the following problems: First, the texture is rough and hard, poor palatability, low feed intake, and long residence time in the digestive tract, which affects the feed intake of livestock. Second, the feeding value is low. As the crop matures, the lignin in the cell wall of the stem increases and cross-links with the hemicellulose molecules, embedding the cellulose molecules inside, forming a stable and complex complex of lignin, hemicellulose and cellulose, which makes anaerobic microorganisms The secreted enzyme is also difficult to decompose, and its digestibility is only 30% to 45%, or even lower. The third is low nitrogen content and ...
