This is a research that was conducted on animals with some references to some resources that has specifically addressing the subjects of research in this experiment. This article is about a research that was conducted and it is employing an experimental design. It is also having a problem statement that is being addressed by a null and alternative hypothesis. The most difficult part of this experiment was the stage of selecting or rather identification of the most appropriate model of the animal that would be used in the experiment. There were also some other practical considerations that were noted such as defining the right control group,  determining the number of animals that are needed in each group, random assignment of the animals to control or treat in the group.

In this experiment, there is a need for randomization of all the assigned animals. This is the only way that skewed data will be avoided. To achieve, the total population must be defined first in terms of strain, age, sex, weight, breed and all the animals that are involved must be identified by a unique number. These numbers should then be drawn out of a hat and the  ones that are selected should take part in the experiment. This is the method that is used in this experiment so as to get the type of animals that would be used to conduct the experiment or the study.

It is not easy to conduct such type of experiment and therefore there were some problems that were encountered during the activity. Most of the animals were not responding immediately as they would be expected to respond and this brought about some delays in collecting of data. In addition, some animals noted the existence of some foreign materials on their body and they would like to get rid of them or eliminate them.
