Abstract

The amniotic fluid of 76 sows were tested for dry matter (DM), ash, organic matter (DM), Na, K, Cl, protein, glucose, urea, and ammonia levels as well as for acid phosphatase activity, between 21 and 42 days of pregnancy. Significant decreases in DM, ash, Na, K, Cl, and protein concentrations as...
