| Abstract | The nutritional value of flaxseed meal (FSM, containing 12% oil) was measured in growing pigs and adult sows. The effect of their inclusion in balanced diets on the growth of pigs and the quality of their carcass was also tested. The energy values of the FSM were 3526 kcal DE and 2448 kcal NE/kg DM in growing pigs and 3517 kcal DE and 2441 kcal NE/kg DM in sows. The growth study was performed on pigs (males and females) weighing 32kg at the beginning of the experiment and 115 kg at the end. The diets contained barley, wheat, peas, soybean meal and 0, 5, 10 or 15% FSM, at the expense of wheat and soybean meal. The average daily gain of the pigs was 950, 940, 910 and 920 g/d. The differences were not significant (P = 0.60) and no difference was observed for feed intake (P = 0.43) and feed conversion ratio (P = 0.23) either. The analysis of the carcasses revealed a significant (P < 0.001) increase in the content of α-linolenic acid in back fat (2.5 mg/g tissue per additional % FSM in the diet) and in the loin (0.33 mg/g tissue). As a conclusion, diets containing up to 15% FSM do not affect the growth of the pigs and increase the content of omega-3 fatty acid of their carcass. |
