Biosecurity and livestock – Overview

Feb 12, 2025

Overview

Biosecurity refers to practices designed to prevent, reduce or eliminate the introduction and spread of disease. Concerns over the spread of animal diseases, particularly those of foreign origin, are high within the livestock industry.

Livestock diseases can affect any type of operation regardless of size. Biosecurity practices tailored to each operation minimize the introduction and/or transmission of disease:

on a given farm
between farms
between species

Importance of biosecurity

Biosecurity plays a vital role in sustainable livestock production. Principles of biosecurity have become the foundation for animal health which has an associated relationship to food safety, trade, and control of zoonotic diseases. Biosecurity practices are essential to maintaining market access and preventing the occurrence of Foreign Animal Disease (FAD) in Canada.

Biosecurity practices can:

prevent the introduction and spread of disease
protect humans from zoonotic diseases (diseases that are transmissible between animals and humans)
demonstrate commitment to animal health and food safety
be used as a recovery tool if disease incursions occur
save money spent on disease recovery costs

Video: Turning Data into Better Decisions: BioCV's Intelligent Monitoring System for Modern Pork Producers

In this exclusive interview, Jens Kjaer, CEO of BioCV Inc., discusses the North American launch of the BioCV Intelligent Sow Monitoring System and how advanced sensor technology and machine learning are changing the way producers manage sow herds. Using smart ear tags that continuously monitor temperature, behavior, and movement, the system provides real-time alerts for heat detection, farrowing, fever, lameness, and other critical health events—often before they become visible to barn staff.

Kjaer explains how the technology helps producers improve breeding efficiency, reduce non-productive days, identify health challenges earlier, and better support sows during farrowing. He also shares how BioCV's predictive analytics can help operations optimize labor, improve piglet survival, reduce sow losses, and enhance overall productivity in today's increasingly data-driven swine industry.

Learn how this innovative technology is giving producers actionable insights on every sow, every day, helping teams move from reactive management to proactive decision-making while improving both animal welfare and profitability. www.biocv.info/lisa-sow
