The effect of protein source in late pregnancy feed on the occurrence of agalactia post partum in the sow.

The effect of an all vegetable protein diet on the occurrence of agalacatia was studied. The experiment was performed in a commercial one thousand sow unit with an average frequency of agalactia of 50%. The all vegetable diet significantly reduced the rectal temperature 48 h post partum and the number of medical treatments required. The litter size at weaning was larger (p greater than 0.05) in the group on the all vegetable protein diet.
