简介：
Overview
This protocol demonstrates how to provide practical meaningful environmental enrichment for pigs housed on slatted flooring and how to collect saliva samples non-invasively for cortisol measurement, a biomarker for acute stress.
Key Study Components
Area of Science
- Animal welfare
- Environmental enrichment
- Stress measurement
Background
- Pigs are often housed in environments that may not meet their behavioral needs.
- Environmental enrichment can enhance animal welfare.
- Saliva sampling is a non-invasive method for assessing stress.
- Cortisol is a key biomarker for evaluating stress levels in animals.
Purpose of Study
- To improve the welfare of pigs through environmental enrichment.
- To demonstrate a method for non-invasive cortisol measurement.
- To provide practical protocols for swine farms.
Methods Used
- Preparation of enrichment materials such as jute and cotton ropes.
- Installation of enrichment materials in farrowing pens.
- Collection of saliva samples from pigs.
- Measurement of cortisol concentrations in saliva.
Main Results
- Environmental enrichment can be easily implemented in swine farms.
- Non-invasive saliva sampling is effective for cortisol measurement.
- Improved animal welfare is achievable through these methods.
- Protocols can be adapted for different stages of pig development.
Conclusions
- Environmental enrichment positively impacts pig welfare.
- Non-invasive methods for stress assessment are viable.
- These practices can be standardized across swine operations.
What is environmental enrichment for pigs?
Environmental enrichment involves providing stimuli that promote natural behaviors in pigs, enhancing their welfare.
How is saliva sampling performed?
Saliva samples are collected non-invasively, allowing for stress assessment without harming the animals.
Why is cortisol measured?
Cortisol is a hormone that indicates stress levels in animals, making it a useful biomarker for welfare assessments.
Can these methods be used on any swine farm?
Yes, the protocols are designed to be easily implemented in various swine farming operations.
What materials are used for enrichment?
Materials such as jute and natural cotton ropes are used to create enrichment that encourages exploration and play.
At what stages of life can enrichment be provided?
Enrichment can be provided at different stages, including during farrowing and weaning.
