Forage sorghum was treated with Cold-Flo anhydrous ammonia at ensiling time and compared with untreated silage supplemented with soybean meal at feeding time. One hundred Angus steers were used in the 91-day trial.
Average daily gain of the cattle fed the two silages was very similar. However, cattle fed the amonia-treated forage sorghum consumed less feed than controls, resulting in a substantially better (16.7%) conversion by steers on the ammonia-treated silage ration.
The result of this experiment indicate that Cold-Flo anhydrous ammonia is efficiently utilized as nonprotein nitrogen source with forage sorghum silage. Further research is necessary with other low energy silages to confirm this original finding and expand the beneficial uses of this inexpensive silage additive for producers.
