No Adverse Effects from Feeding Roasted Green Soybeans

The pigs readily accepted and consumed the experimental diets. As indicated in Table 1, pigs achieved high growth rates on both treatments and no differences (P>0.10) were observed between the two dietary treatments. There were no effects of dietary treatments on any of the carcass characteristics that were evaluated, including meat and fat color scores. This was consistent with visual and subjective evaluation of carcass quality and meat color.

In conclusion, no negative effects were observed for any of the growth and carcass characteristics that were evaluated. There is no concern about feeding green roasted beans to pigs.
