Animals testing is widely used on regular basis in industries, scientific research labs for testing of consumables, drugs etc.
They are used under some regulations as per the local laws.
The animals in many experiments experience severe pain and suffering.
They are also grown up for the purpose of research experiments.
Mostly wild animals or those available in nature can’t be used and hence animals grown in the labs are used.
Why are animals used for testing:
They are mostly used to safe guard humans from direct exposure of substances used by direct internal consumption or external applications on the skin. The use of animals in experimentation helps
Detect toxicity: Animals are used for testing the harmful or poisonous effects of drugs, food supplements etc if any. If the substances fail to pass their test in animals due to severe adverse effects or toxicity then they are not tried for human use.
Fixing the dose or quantity: Every drug, food nutrient, vitamins, supplements we take are recommended at fixed quantities or doses. These doses are in the safe range for consumption and also produce the desired effect on the body. Thus tests on animals helps in fixing the correct dose or quantity of drugs or supplements so as to be in safe and effective range.
To study the mechanisms: Animals have body function and physiology similar to humans and hence, they act to mimic human response and behavior to substances. The mechanism of muscle contraction, heart beat, circulation is easily understood by study on animals. Further how a drug acts in the body like by either rise in heart beat, circulation or respiration rate can be understood by scientific testing on animals.
To know the time spent in the body: Animals studies of any substance helps in understanding the time spent by the substance in the body before its elimination by excretion. The more the time spent, the more the chances of poisoning, accumulation, adverse effects and the duration of it’s effects on the body. By conducting blood and urine tests on animals after administration of test substance, it is possible to know the extent of time spent by the substance in the body.
