Description
Technical Field
The invention belongs to the field of bioengineering, and particularly relates to a production method and application of a palm meal fermented feed.
Background
With the development of animal husbandry, 40 to 50 percent of raw grains are directly used in the feed processing process every year in China, so that the problems of feed grain shortage and grain competition between people and livestock are increasingly prominent. The research on the effective utilization of the unconventional raw materials in the livestock and poultry breeding becomes a hot spot of the industry. The palm meal is a byproduct of palm kernel shelling and oil pressing, and is rich in resources and low in price. The palm meal has 14-21% of crude protein and 8-17% of lipid, can provide protein and energy for animals at the same time, and has very good application potential in livestock and poultry feeds. However, the content of the crude fiber of the palm meal is up to more than 15%, the content of non-starch polysaccharide is high, and especially the proportion of mannan is large, so that the palatability is influenced, the conversion and utilization of animals are hindered, and the application of the palm meal in livestock and poultry feed is greatly limited.
From the aspects of nutritional value and chemical components, the palm meal has extremely high fermentation plasticity, the high-content crude fiber and non-starch polysaccharide can be reduced through the fermentation process of non-starch polysaccharidase and microorganisms, the energy utilization rate is improved, the digestion energy and the metabolic energy are correspondingly improved, and particularly, the non-starch polysaccharide can be fermented to generate a large amount of functional oligosaccharide, so that the immune function of animals is improved. Penghai dragon and other reports report that 4% -7% of daily ration of fermented palm meal is added to feed growing pigs, so that the feed intake and growth development of the pigs can be improved; 4% of fermented palm meal is added into the daily ration, the daily egg weight, the Ha's unit and the egg white height of the laying hens are all improved, and the color grade of egg yolks, the egg laying performance of the laying hens and the egg quality are all improved to different degrees.
The palm meal biological treatment method mainly comprises a microbial fermentation method, a biological enzymolysis method and an enzyme-bacterium synergistic fermentation method. The microbial fermented palm meal can produce rich functional metabolites (lactic acid, volatile fatty acid, bacteriocin and the like) and a large amount of probiotics, but the main anti-nutritional factors (40-42% non-starch polysaccharide) in the palm meal are not fully degraded, a large amount of anti-nutritional factors still exist in the fermented palm meal finished product, the digestibility of energy and fiber is not fundamentally improved, and the feeding value is not effectively improved. The biological enzymolysis of the palm meal refers to that the macromolecular polysaccharide is cut into oligosaccharide and the like by adopting endo-hydrolytic enzymes such as beta-mannase, beta-xylanase and the like so as to eliminate the anti-nutritional effect and improve the digestibility of the palm meal. However, the cell wall structure of the palm meal is compact, the combination efficiency of the biological enzyme and the substrate is low without pretreatment, and the main anti-nutritional factors of the palm meal, namely mannan and the like, are difficult to completely eliminate. Meanwhile, compared with the fermented palm meal, the enzymolysis palm meal is lack of metabolites with immune functions, such as organic acids, bacteriocins and the like. In addition, at present, only endo-hydrolase is considered for enzymolysis, the endo-hydrolase can only hydrolyze and cut polysaccharides into oligosaccharides or polysaccharides, substrate feedback inhibition exists, the polysaccharides such as mannan cannot be completely hydrolyzed, and different exoglycosidases are required for complete hydrolysis, such as beta-mannase, alpha-galactosidase and the like.
