ΣΥΜΒΟΛΗ ΣΤΗΝ ΚΑΤΑΡΤΙΣΗ ΤΟΥ ΒΕΛΤΙΣΤΟΥ ΣΧΕΔΙΟΥ ΕΠΙΛΟΓΗΣ ΤΩΝ ΧΟΙΡΩΝ ΣΤΗΝ ΕΛΛΑΔΑ

THE ESTIMATED ECONOMIC WEIGHTS OF THE MORE IMPORTANT TRAITS IN SWINE ARE: - LITTER SIZE IN WEANING 170 DR/PIG, - FOOD CONVERSION EFFICIENCY 1440 DR/PIG, - DAILY GROWTH RATE 2 DR/PIG, - PERCENTAGE OF LEAM IN CAREASS 130 DR/PIG. THE EVALUATION OF THE TOTAL BREEDING VALUE IS BASED ON RESTRICTED SELECTION INDEXES FOR MEAT QUALITY. THE CRITERIONS OF EFFECTIVENESS ALTERNATIVE SELECTION PLANS IN THIS STUDY ARE: (1) NET ECONOMIC RETURN AND (2) SELECTION RESPONSE. THE OPTIMUM BREEDING SELECTION PLAN OF SWINE IN GREECE APPEARS AS FOLLOWS: - ESTABLISHMENT OFA NUCLEUS HERD, SIZE 1365 SOWS, - ESTABLISHMENT OF CENTRAL TESTING STATIONS, OVERALL CAPASITY ABOUT 2184 INDIVIDUAL PENS, - FIELD PERFORMANCE TESTING WITH ABTESTING IN STATION FOR THE SELECTION OF NUCLEUS BOARS AND SOWS, - CULLING OF BOARS AND SOWS AFTER SIX MONTHS AND 1-2 LITTERS REPRODUCTIVE LIFE, RESPECTIVELY.RATIO OF BOARS TO SOWS 1:250 OR 1:30 WITH OR WITHOUT ARTIFICIAL INSEMINATION. INSEMINATION.
