Ruminant parameters grow mortality

CLEM.Resources.RuminantParametersGrowMortality

Provides the parameters for the original mortality calculations of Grow ruminants.

With the introduction of a range of Ruminant growth models, ruminant mortality was moved to its own activity. The separation of Ruminant death from growth also helps in ensuring the user can understand all the mortality being applied to the herd. These parameters relate specifically to the Ruminant Death Group that applies the original condition adjusted base mortality to adults and juveniles.

This component is placed as a child of the Ruminant parameters holder for each Ruminant type.

The following breed parameters are provided by user level and category.

These farm level parameters are usually specified for each simulation and available for all user levels.

These parameters are used to calculate the age adjusted mortality rate.

The Body Condition Score below which the additional poor condition mortality is applied to the individual. See the Basic/General section above for the parameters required and Individual ruminant for details of the calculation of Body Condition Score.

This functionality is now handled by the Ruminant Group Death Condition which is used with Ruminant death.

The additional mortality rate for individuals at the lowest Body Condition Score. Individuals at the lowest score will have this additional chance of dying applied each timestep based on their poor body condition as a result of under nutrition. See the Basic/General section above for the parameters required and Individual ruminant for details of the calculation of Body Condition Score.

This functionality is now handled by the Ruminant Group Death Condition which is used with Ruminant death.

This parameter defines the body weight as a proportion of Standard Reference Weight below which the individual will die.

This functionality is now handled by the Ruminant Group Death Condition which is used with Ruminant death.

Three parameters (the exponent, coefficient and intercept) are provided to determine the age adjusted mortality rate.

See Grow ruminants for details of mortality/survival calculations.

Two parameters (the exponent and coefficient) are provided to determine the adjusted mortality rate based on the mothers weight.

A third parameter (maximum) is used to define the maximum juvenile mortality possible.
