Abstract
Twenty-four growing hogs with an initial weight of about 80 lb. were fed a control ration and rations containing 20% and 50% 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% black-eyed peas gained about 38% less weight than the controls (1% level of statistical significance). Feed consumption and utilization were apparently reduced by the addition of black-eyed peas. There was no evidence of toxicity.
