Abstract: | The experiment investigated the effects of increasing dietary levels of bacterial protein meal (BPM) on various blood parameters
reflecting protein and fat metabolism, liver function, and purine base metabolism in growing pigs. Sixteen barrows were allocated
to four different experimental diets. The control diet was based on soybean meal. In the other three diets soybean meal was
replaced with increasing levels of BPM, approximately 17%, 35%, and 50% of the nitrogen being derived from BPM. Blood samples
from the jugular vein were taken when the body weights of the pigs were approximately 10 kg, 21 kg, 45 kg, and 77 kg. The
blood parameters reflecting fat metabolism and liver function were not affected by diet. Both the plasma albumin and uric
acid concentrations tended to decrease (P = 0.07 and 0.01, respectively) with increasing dietary BPM content, whereas the plasma glucose concentration tended to increase
(P = 0.07) with increasing dietary BPM content. It was concluded that up to 50% of the nitrogen could be derived from BPM without
affecting metabolic function, as reflected in the measured blood parameters. |
