Evaluation of inoculant and NPN silage additives: a summary of 26 trials and 65 farm-scale silages

Results from 26 trials comparing fermentation, dry matter (DM) recovery, and effects on cattle performance of inoculated or nonprotein nitrogen (NPN)-treated silages vs. controls were summarized using paired t-test analysis. Inoculants consistently improved fermentation efficiency, DM recovery, feed conversion, and gain per ton of crop ensiled in both corn and forage sorghum silages. The use of NPN, particularly urea or anhydrous ammonia, adversely affected fermentation efficiency, DM recovery, avg daily gain, and gain per ton of crop ensiled, particularly for the higher moisture forage sorghums.

Adding fat and/or sodium bicarbonate to steer finishing rations that contain wheat

Adding .6 pound fat or .22 pound sodium bicarbonate (soda) to finishing rations containing rolled wheat significantly improved performance and appeared to increase the substitution value of wheat. Both fat and soda increased feed intake. The improved gains from adding fat corresponded to increased energy intake. However, soda seemed to enhance nutrient utilization. There was more response to fat when we fed 100 percent vs. 50 percent wheat, but feeding 100 percent wheat depressed performance, with or without fat, to unsatisfactory levels.

New developments in feeding wheat to cattle

At least for the varieties we studied, hard red winter wheat was superior to soft red winter wheat in beef cattle rations. That contradicts the perception that feed wheats should be soft. The net energy values of Larned hard wheat and Hart soft wheat were 102% and 99% that of corn, respectively. Adding Rumensin® to wheat rations improved performance, probably by reducing acidosis instead of increasing ration net energy value. There was a positive associative effect when wheat and milo were fed together but not when wheat and corn or corn and milo were combined. Steer performance was improved by adding 3% fat to rations; that improvement was proportional to the amount of wheat in the rations and was probably due to the fats added energy, Steers that were fed fat graded better and gained more uniformly. When 100% wheat was fed, overall performance was satisfactory only when fat was included.

Influence of sustained rumensin release on steer performance and forage utilization

Ionophores such as Rumensin play an important role in today’s cattle industry because of their ability to enhance gain and efficiency. Administration of Rumensin to grazing cattle has previously been limited to situations in which supplementation systems were feasible. Recently, a Rumensin-containing, slow release, intraruminal bolus has been developed. This device allows cattle to be bolused at the beginning of a grazing period and then slowly releases the ionophore over an extended period. Although some data are available regarding the response of cattle that have received the Rumensin bolus, no information is available on how this bolus affects forage utilization. Therefore, our objective was to compare gains and forage utilization under intensive-early stocking in cattle receiving a Rumensin bolus.
