Sewage-grown algae as a protein supplement for swine

  • H. F. Hintz (a1) and H. Heitman (a1)

In two trials with 48 pigs it was found that when algae supplemented with certain B-vitamins replaced fish meal on an equal-nitrogen basis in a diet based on barley and fish meal there was no decrease in rate of gain or feed conversion efficiency. When vitamin B12 was omitted from the algal diet, there was a decrease in rate of gain. There were no consistent differences in carcass characteristics between pigs fed on the algal diets and those fed ondiets containing fish meal. Digestibility studies indicated that algae are low in digestible energy, but their protein is 70% digestible.
