Validation of the Kinovea® software program for obtaining zoometric measurements in swine: Comparison with traditional methods: Producción y Salud Animal
Zoometry has proven to be a valuable tool for differentiating individuals within and between populations. The objective of this study was to validate the use of the Kinovea® V2023.1.1 (KV) software to obtain zoometric measurements. 50 crossbred sows (Duroc x Landrace x Yorkshire) aged over eight mon...

The objective of this study was to validate the use of the Kinovea® V2023.1.1 (KV) software to obtain zoometric measurements. 50 crossbred sows (Duroc x Landrace x Yorkshire) aged over eight months were used, seven morphometric variables were measured with three stick zoometers and photographs were taken in the lateral plane to evaluate the morphometric measurements in KV and the rear elevation was used a cross as a reference measurement to calibrate the KV. The independent Student’s T test was applied and no significant difference (p>0.05) was found between the two methods. The results of manual measurements by cane zoometers were: height at the withers 75.9 ± 4.85 cm, rump 81.14 ± 5.25 cm and tail rise 73.2 ± 5.35 cm; longitudinal diameters 106.9 ± 8.44 cm and sternal dorsum 42.7 ± 4.07 cm; head lengths 31.38 ± 3.69 cm and rump 34.66 ± 4.08 cm. The results of measurements obtained with KV were similar: height at withers 75.9 ± 4.85 cm, rump 82.24 ± 6.11 cm, tail rise 74.50 ± 6.26 cm; longitudinal diameters 108.87 ± 11.46 cm and sternal dorsum 44.07 ± 4.78 cm; head lengths 31.00 ± 5.10 cm and rump 34.89 ± 3.87 cm. It is concluded that the use of Kinovea® is feasible to obtain body measurements in pigs without resorting to invasive methods that cause stress to the animal. |
