The typical mortality rate for kids is 10% for kids before weaning and 5% for mature animals. Mortality rates will vary depending on your management.
For example, on a 25-doe goat farm producing 1.8 kids per female per year, these percentages translate into the following annual mortality estimates: five pre-weaning goats and one doe. Using average weights of 30 pounds for a pre-weaning goat and 125 pounds for a doe, the amount of mortality produced by the typical 25-doe operation is approximately 275 pounds per year. Stillborn kids, mummified fetuses, and afterbirths add to these estimates.
