**Animal Mortality Rate Tools:** Are you searching for a tool to calculate the mortality rate of animals? Then you are on the right page. We are providing you with a free tool to calculate the death rate of animals easily. By giving inputs you will get output. If you do not know what is mortality rate and how to calculate it then check out our complete page to know everything about the mortality rate of animals.

The animal mortality rate is basically a death rate that is taken place in the animal population. As the animal population increases it is impossible to avoid mortality. But we can control the mortality. The mortality rate is mainly expressed in percentages. It measures the number of deaths in your animal population that occurs over a particular time period.

Here we are going to see the simple formula to calculate the mortality rate.

The formula for mortality for the particular time period.

**Mortality = Opening stock + Number of newborns - Number of animals sold - Closing stock**

Where

Opening stock - No.of animals grown at the beginning of the season.

Closing stock - No.of animals grown at the end of the season.

The formula for mortality rate

**Mortality rate = Mortality / (Opening stock + No.of newborns) x 100%**

Here are the guidelines that are given below to calculate the mortality rate.

- Firstly, note down the values that are given in the problem.
- Then apply the formula of mortality rate.
- Substitute the values in it and simplify them.
- Finally, you will get the answer easily.

**Question:** Calculate the mortality rate for two cattle forms, as both farms have a population of 200 cattle each. As they have a disease outbreak, One farm recorded that 53 cattle are infected, with 18 dead in it. On another farm, 19 cattle are infected and 9 are dead.

**Solution:**

Given, Farm one =200

Farm two = 200

Disease infected cattle in farm one = 53

Dead cattle in farm one = 18

Disease infected cattle in farm two = 19

Dead cattle in farm two = 9

**Farm 1:**

Number of deaths = 18

**Mortality rate = Mortality / (Opening stock + No. of newborns) * 100%**

Mortality rate = 18/200 x 100%

= 9.0%

**Farm 2:**

Number of deaths = 9

**Mortality rate = Mortality / (Opening stock + No. of newborns) x 100%**

Mortality rate = 9/200 x 100%

= 4.5%

Hence the mortality rate of farm 1 and farm 2 is 9.0% and 4.5%
