Determination of the minimum number of animals to be used; The selection of appropriate experimental methods, miele t 8861 wp edition 111 control of environmental factors, can be achieved through standardization will be held in the hosting and maintenance of animal species. Standardization will reduce the variation in results.
Try the following conditions should be reviewed to decide before;
All environmental and genotypic a bunch of animals used in experiments with the experimental factors and try to be an example of phenotypic direction is called a full standardization.
Partial standardization; age of the animal, sex, body weight, physiological activity period, the surrounding temperature miele t 8861 wp edition 111 level, the color of the light intensity and duration of a certain period in nature can change the results of such experiments and a certain population, the generalization that may result possible by ensuring that a sample of all the factors miele t 8861 wp edition 111 that can be obtained.
Standardization miele t 8861 wp edition 111 of the trial; Experiment should be repeated in case the same or a different species from both experiments could be variations within experiments. This variation in the environment of animals, heat, light and physiological location, arises from differences between the genotype of an individual. miele t 8861 wp edition 111 Standardization of inter- and intra-assay variation of trial experiments to minimize possible.
Individual miele t 8861 wp edition 111 differences stemming from genotypes can be eliminated theoretically by using an example miele t 8861 wp edition 111 genetically engineered animals. This is practically not possible when using animals in experiments so that the genotype, sex, age, and similar animals in terms of birth weight is selected. Thus, partly by standardizing animal.
Recombinant inbred miele t 8861 wp edition 111 (RI) strains
Distant relatives strains (outbred) * a group from a colony grown as random mating closed for at least 4 generation. The selected individuals are required to be less than 1% of the degree of relationship.
Mutant driven away a lot of inbreeding miele t 8861 wp edition 111 due to the advantageous ability to reproduce, but in terms of appearance and mutant individuals are disadvantaged because of the magnitude of the variation in the direction of tissue compatibility.
ü unrelated inbred descendants miele t 8861 wp edition 111 of two individuals miele t 8861 wp edition 111 in the F2 generation by crossing is formed by mating between the brothers. Is referred to as the progenitor strain.
a close relative of the animal gene mutation or gene transfer with genetically modified. These amendments are transferred to the next generation. To an animal in inbred strains (to determine traits) are formed by the transfer of a foreign gene allowed.
CRF animal flora exact composition is unknown, but is assumed to have lost some of the normal miele t 8861 wp edition 111 flora. miele t 8861 wp edition 111
the construction of non-animal groups are having some special pathogens. That does not mean free of all microorganisms. Animals were free from specific microorganisms and parasites, but you can move the others.

Body temperature
When simple structure miele t 8861 wp edition 111 which can not control the body temperature and the ambient temperature is significantly affect their activity. They slow down the inpatient metabolic function in low temperature for hibernation activities.
Large animals; body surface / body weight miele t 8861 wp edition 111 ratio, while the smaller miele t 8861 wp edition 111 experimental animals, this ratio is greater. Therefore, energy required to maintain constant body temperature in less than large animals.
Relative humidity is high, the cage, the amount of ammonia increased by suffocation due to excessive moisture in the respiratory system of the wet and moldy feed and bedding, leads to a lot of micro-organisms from spreading into the shelter by faster urea.
ü If the relative humidity is low, the increase in pollution due to excessive dust in the environment miele t 8861 wp edition 111 and animals due to irritation of the respiratory tract causes respiratory problems arise. Therefore shelter to do good ventilation to reduce miele t 8861 wp edition 111 the heat and keep the water in the environment must be ensured.

Warm-blooded animals recognize miele t 8861 wp edition 111 their caregivers dealing with her since birth and does not show aggression. But if a stranger approaches them may show aggression.
