Blood meal as a protein source in diets for growing-finishing swine

Abstract

Sixty-four Landrace pigs (32 barrows and 32 females) were used in an experiment to evaluate 0, 2, 4 and 6% levels of commercial swine blood meal in swine diets during growing-finishing period. The results of average daily gain during the whole period (25-95kg) were 693, 709, 714 and 705 grams, to the levels from 0% to 6% respectively, and the differences among them were not significant (P>0.05). The average feed intake (Y = 2.156 + 0.038 X) and the feed/gain ratio (Y = 3.0733 + 0.0489 X) increased (P<0.05) when the level of blood meal in the diet increased from 0% to 6%. It was concluded that the blood meal used in this experiment was not suitable to replace at any level the protein supplied by the soybean- meal.
