Description
Technical field
The present invention relates to Bioexperiment instrument field, especially relate to a kind of full-automatic monogastric animal bionic digestion instrument.
Background technology
In modern farming, the objective nutrient biological value accurately evaluating feedstuff is the primary decision-making basis determined Animal nutrition requirement and optimize feed formula.In China, of a great variety, the renewal speed of feedstuff is faster in situation, if at least need many decades with the biological value of the whole general survey of animal experiment method, prediction feed nutrient, and result only can obtain very limited static parameter.Therefore, in order to break through the technical bottleneck that restriction China feed nutrient biological value parameter upgrades, designing a kind of science, accurately and rapidly feed nutrient biological value testing tool is be badly in need of, and it can be modern farming and provides technical support.
From the sixties in 20th century, in order to realize the rapid evaluation to feed nutrient biological value, scholars is studying the simulation digestion techniques of feed nutrient always, and oneself is through establishing a series of normalized working specification.Such as, the middle and later periods in 20th century, it is pig, the chicken feed effective energy value zymetology assessment method working specification of system that Chinese scholar Zhang Ziyi etc. establish with pepsin-intestinal fluid; It is the pig feed digestible energy value rapid method for assessment working specification of system that Denmark scholar Boisen and Fernandez establishes with pepsin-pancreatin-carbohydrase; Canada scholar Gauther, Savoie etc. establishes with the proteinase dialysis pig that is system, chicken feed amino acid digestibility rapid method for assessment.But, the intestines and stomach simulation slaking apparatus that these methods adopt is mainly with based on the simple experiment materials such as triangular flask, test tube, dialysis tubing, in each step digestion process, the separation etc. of the change of pH value, the adding of digestive juice, product is all realized by mode manually, therefore, the repeatability of this kind of simple analog digestive system is poor, the maximum deviation of Duplicate Samples reaches more than 4%, and, its precision measured mainly relies on the regression correction of mathematical model, and this system breeds larger randomness and instability.Along with the development of science and technology, these methods have also become the technical bottleneck of the development of animal and fowl fodder nutrient biological value rapid method for assessment and application.
Compared with simulating digestive system with early animal intestines and stomach, Dutch TNO food and nutrient research comprise Stomach duodenum, jejunum, ileum four continuous analog digestion chambers in the pig all-digestive tract Bionic digestion system of nineteen ninety-five development.This system can simulate the absorption of emptying, the wriggling of small intestine of stomach, the secretion of digestive juice and small intestine.In addition, Canada food research and centre of development compared with within 2005, develop and simulates digestive system with early animal intestines and stomach, Dutch TNO food and nutrient research the pig all-digestive tract Bionic digestion system developed in nineteen ninety-five comprise Stomach duodenum, jejunum, ileum four continuous analog digestion chambers.This system can simulate the absorption of emptying, the wriggling of small intestine of stomach, the secretion of digestive juice and small intestine.In addition, though mankind's epimere stomach and intestine Bionic digestion system of developing in 2005 of Canadian food research and centre of development and Dutch TNO food and nutrient research design differ greatly, both are functionally comparatively similar.Visible, Bionic digestion system of new generation all with the high fidelity of digestion process for starting point, particularly Bionic digestion process is all realize automatic control by computing machine.But the design original intention of these Bionic digestion systems is the research for aspects such as gastrointestinol microorganism growth, pharmacology metabolism, and be not suitable for mensuration fodder energy, protein, amino acid whose digestibility.This is mainly because the alimentary canal of this kind of bionic device is long, and feed is circulate successively in order between each section of alimentary canal, is easy to form the blocking of feed in a certain section of Bionic digestion road, remain.In design theory, these systems can not meet the theory of " all-in and all-out " in feed nutrient biological value mensuration.
In sum, how designing a kind of can realistic simulation feed Bionic digestion instrument that is digested in the intestines and stomach of nonruminant, absorption process be the technical matters that need solve at present.
