Infrared thermography offers a non-invasive method for diagnosing mastitis in sheep. Elevated udder temperatures detected by infrared imaging accurately identified subclinical mastitis, aiding in early detection and management.
Area of Science:
- Veterinary Medicine
- Animal Science
- Diagnostic Imaging
Background:
- Mastitis is a significant concern in sheep farming, impacting milk production and animal welfare.
- Accurate and early diagnosis of mastitis is crucial for effective treatment and herd management.
- Current diagnostic methods may be invasive or time-consuming.
Purpose of the Study:
- To evaluate the efficacy of infrared thermography as a diagnostic tool for mastitis in sheep.
- To correlate udder surface temperatures with milk somatic cell counts and milk composition.
- To determine if infrared thermography can differentiate between clinical and subclinical mastitis.
Main Methods:
- Infrared thermography (FLIR System Series-i®) was used to capture weekly udder temperature images from 37 Santa Inês ewes.
- Milk samples were collected for somatic cell count and analysis of fat, protein, and lactose levels.
- Statistical analysis, including canonical analysis, was performed to assess the diagnostic accuracy of temperature data.
Main Results:
- The clinical mastitis group exhibited higher fat and protein levels and lower lactose levels in milk.
- Ewes with subclinical mastitis showed significantly higher udder temperatures compared to healthy controls.
- Udder temperature data successfully classified animals into different mastitis groups, with clear differentiation of subclinical cases.
Conclusions:
- Infrared thermography is a viable, non-invasive method for diagnosing mastitis in sheep.
- Udder surface temperature measurements can effectively identify subclinical mastitis, enabling prompt intervention.
- This technology holds potential for routine mastitis screening in sheep flocks.
