Summary

Summary Not Available – First paragraph follows:

Feeding trials with rations including ground black-eyed cowpeas for swine resulted in reduced consumption and utilization of feed as well as lower gains—but there was no evidence of toxicity. Twenty-four growing hogs with an initial weight of about 80 pounds were fed a control ration and rations containing 20 per cent and 50 per cent ground black-eyed cowpeas (Vigna sinensis) for an experimental period of 70 days. As the percentage of black-eyed peas increased, gain in weight decreased. The pigs on the ration containing 50 per cent black-eyed peas gained about 38 per cent less weight than the controls.
