None.
TSH is a signal fo rthe thyroid to make and release more thyroid hormone. If the thyroid is removed TSH wil have no effect.
Rats have a higher metabolic rate than frogs.
Hypophysectomized rats do not have the thyroxine with which to regulate metabolic rate properly. Thyroxine replacement can allow for the normalization of the metabolic rate (as it does in humans with hypothyroidism!).
Rats have a high metabolic rate because they are small animals with a relatively large surface area-to-volume ratio, leading to faster heat loss and requiring more energy to maintain their body temperature. Additionally, rats are active creatures with quick movements, which also contributes to their high metabolic needs.
Energy-restricted diets led to lowering of the metabolic rate and body temperature
The effect of administering thyroxin on each of the rats was the baseline metabolic rate increased in each rat. Thyroxin was the most important hormone in maintaining metabolism and body heat.
Wistar rats appear to be an interesting model to study the changes related to metabolic syndrome. They can have a lifespan of two to three years.
The survival rate of rats undergoing surgery is typically high, with most studies reporting rates above 90.

Rats obtain energy primarily from the food they consume, which includes grains, fruits, vegetables, and protein sources. Their digestive system breaks down these foods into glucose and other nutrients, which are then metabolized to produce energy. Additionally, rats have a high metabolic rate, allowing them to convert food into energy efficiently to support their active lifestyles.
The main effect is the death of the rats. However, be careful if you have pets. Put the poison in protected places, so that your pets remain safe.
