Dairy Cow Biosecurity Overview

There is a real risk of disease in your dairy cattle herd. As a dairy cattle producer you are aware of many of the common diseases that could potentially affect your animals. You have probably also noticed that diseases which exist in some groups of animals in your farm do not exist in other groups. For instance, calves can have a disease not present in cows, and animals in one barn may have a disease not present in another.

Biosecurity is an essential part of maintaining your herd's health as well as the profitability of your operation, an overall plan for your farm is essential. Even if you practice some biosecurity measures now, a plan is needed to make your farm as safe from disease as possible. This plan will allow you to determine the measures needed to set up a comprehensive program to protect your herd in the best way possible.

Implementation of sound biosecurity procedures will reduce the chance of the spread of a disease among the different groups of animals within the farm, and it will also reduce the chance of a disease being brought to your farm.

A biosecurity plan must include a standard health protocol. This protocol documents standard operating procedures for maintaining herd/flock health, routine husbandry and health procedures, and specific methods to identify, separate, and treat sick animals.

Below is a list of biosecurity measures that are categorized under general topics. These are best management practices, and this list can be used to develop your own biosecurity plan.
