Abstract

FIFTY-SIX PIGLETS FROM 6 LITTERS WERE USED TO EVALUATE THE IMPORTANCE OF APPLYING IRON TO PREVENT ANEMIA IN PIGLETS KEPT IN AN OUTDOOR SYSTEM. THE TREATMENTS WERE INTRAMUSCULAR APPLICATION OF 200 MG OF DEXTRAN IRON TO HALF OF EACH LITTER AT THE THIRD DAY OF AGE (I) AND THE OTHER HALF REMAINED WITHOUT IRON (WI). THE PIGLETS WERE WEIGHED AND BLOOD SAMPLED AT 0, 10 AND 21 DAYS OF AGE. THE HEMATOLOGICAL AND WEIGHT GAIN DATA WERE ANALYZED USING A BLOCKS PAIRED ”T” TEST. THERE WAS NO STATISTICAL DIFFERENCE (P > 0.05) IN WEIGHT GAIN AT 0, 10 AND 21 DAYS OF AGE. VALUES OF HEMATOCRIT (I 0.42 L/L AND WI 0.38 L/L) AND HEMOGLOBIN (I 120.4 G/L AND WI 109.3 G/L) WERE SIGNIFICANTLY (P < 0.05) HIGHER AT 21 DAYS OF AGE IN PIGLETS FROM TREATMENT I. HOWEVER, THE HEMATOCRIT AND HEMOGLOBIN VALUES IN PIGLETS FROM TREATMENT WI WERE ABOVE THOSE ASSOCIATED TO ANEMIA. THE RESULTS FROM THIS STUDY SUGGEST THAT IT IS NOT NECESSARY TO APPLY IRON TO PREVENT ANEMIA IN PIGLETS KEPT IN AN OUTDOOR SYSTEM.
