Description
Technical field
The present invention relates to a kind of animal feed, relate in particular expanded pellet diet of kind of experimental dog and preparation method thereof.
Technical background
Animal used as test refers to through artificial feeding, and its microorganism of carrying, parasite are carried out control, and the clear and definite or source of genetic background clearly is used for the animal of scientific research, teaching, production, calibrating and other scientific experiments.Animal used as test is a kind of lived experimental subjects, is described as " reagent of living ", " instrument of living ", has embodied the significance of animal used as test in quality management.The factor that affects Quality of Experimental Animals is many-sided, such as heredity, environment, drinking-water, feed etc.The animal used as test feeding quality is and the closely-related essential condition of Quality of Experimental Animals, also is that the assurance zoopery is carried out with experimental result basic accurately and reliably smoothly.Developed country reaches safely harm to the animal used as test feed hygiene and attaches great importance to, and China is along with the enforcement of GLP, also it is more and more paid close attention to and payes attention to.The standardization of animal used as test feed is the important component part of Laboratory Animal Standardization, is the prerequisite that improves Quality of Experimental Animals.
The Growth and reproduction of animal needs constantly to obtain nutrient and energy from feed.At the experimental animal feeding management aspect, not only to consider normal growth and the procreation of animal, more will consider between some animal individuals of experiment usefulness and reduce otherness as far as possible, must consider that also feed ingredient can not produce disturb experimental result, the phase obtains accurately reliably and experimental result repeatably.At present, to animal used as test, and animal impact that experimental result is produced not yet causes enough attention with disturbing by experiment about feed.In the allotment process, mixed feed tends to potential various unfavorable factor, might produce unexpected impact on the growth of animal used as test and on the reaction of experiment condition.
Summary of the invention
Research finds, the feed of experimental dog requires to contain relatively abundanter and the high protein of quality take the feed that comes from animal body as main, and concerning experimental dog, protein requires that not only amount is many, and amino acid requires more comprehensive, and is easy to digestion.The animal fodder that some must be arranged in the feed of experimental dog could satisfy beasle dog to the needs of protein.Animal fodder also contains abundant iron and b family vitamin.Simultaneously, added a large amount of carbohydrate in the expanded pellet diet of experimental dog provided by the invention.
In addition, the content of trace element in feed plays conclusive effect for the quality of the expanded pellet diet of experimental dog, these micro-content are crossed and low will be affected directly or indirectly that animal used as test grows normally, grows, the physiology course such as hereditary in the expanded pellet diet of experimental dog, and then affect result and the reliability of scientific experiment; Too high levels may cause again animal used as test to poison, and is light then affect growing of animal used as test, heavy then cause animal used as test death, or remains in the experimental animals, finally affects the scientific experiment result.So in the time of the conventional nutritional need of the expanded pellet diet of experimental dog of the present invention, also added the dog necessary trace element of growing.
For addressing the above problem, the invention provides a kind of expanded pellet diet of experimental dog, comprise the mixture that expanded corn powder, corn flour, flour, wheat flour, bean cake powder, corn protein powder, wheatfeed, fish meal, chicken meal, yolk powder, trace element, calcium monohydrogen phosphate, yeast, salt, cod-liver oil, compound dimension he, soybean oil form in the test portion.
