A systems analysis of inter-annual changes in the pattern of sheep flock productivity in Tanzanian livestock research centres
Annual estimates of production traits over a 22 year period (1965-1987) for Black Head Persian sheep (BHP) from Malya and West Kilimanjaro research centers in Tanzania were utilized to analyse variation of flock productivity over time. Principal component analysis was used to anlyse the variation of...
