Selection criteria and fleece characteristics for the Finn sheep
(by Marja-Leena Puntila, Finland)
1-Definition and choice of selection criteria:
The selection objectives are to develop a wool line for the Finn sheep nucleus flock. Research is orientated towards the quantity and quality of the wool.
The selection criteria are:
Our target is to preserve the special characteristics of Finn sheep wool, such as softness, lightness, fineness, elasticity, lustre and different coloured types (pure black, brown and grey).
2-Measurement of fleece characteristics : objective and non-objective measurement of fibre quality
The objective measurements concern the staple length (cm). The average of three estimates measured by a ruler is taken. The fineness grading is subjective but it corresponds with a crimp frequency per 3 cm, so it is in-between objective and subjective measurements.
The subjective measurements are:
3-Management of the collected data within a breed database
After collection of the data, they are stored on a PC in the state farm by a technician, and sent to the Agricultural Research Centre for analysis.
