| Summary | VitaFerm supplementation to cows resulted in a significantly improved body condition score of 4.8 (adjusted from publication) compared with 5.2 (p<.01) over the period Decmber through March; however, the supplementation did not result in significant differences in calf birth weight, weaning weight, average weight per day of age, nor did it result in greater digestible energy, dry matter digestibility, or nitrogen retention. Amaferm appeared to lower the total VFA concentration in the rumen fluid. |

| Summary | Amaferm supplementation resulted in increased ruminal pH at 1 and 24 hours post-feeding compared with non-Amaferm supplemented steers that were fed a low-protein prairiegrass hay diet. NDF degradation of the prairiegrass was improved in the cannulated steers by 26% and in situ by 30%. The addition of Amferm helped alleviate the reduction in digestion associated with the feeding of barley. |

| Summary | Amaferm was added to the rumen fungus Neocallimastix frontalis EB188 at increasing doses. Secretion of cellulase (p< 0.05) and B-gluconsidase as well as VFA production (p< 0.05) was increased in the presence of Amaferm. Amaferm also increased the morphology of the fungi, illustrated by increased stem area, branching and sporangia. |

| Summary | Eighty-four Charolais crossbred heifers (571.4 ± 5.4 lb) were used to determine the effects of Amaferm supplementation on calf performance when fed high forage grower diets in an 84 day study. Heifers were fed a corn-silage and oat hay based growing ration (63% of diet, DM basis). Total ADG was improved by 5.1% with Amaferm compared to control (p <.02). Feed efficiency was also improved by 6.0% (p <.03). Results indicate that Amaferm has a positive effect on heifer growth when fed with high forage-based growing diets. |

| Summary | This natural finishing trial involved 168 head of crossbred steers with a starting weight of 661 lbs. Cattle were fed for 150 days. The main effect of Amaferm treatment was on the diet consisting of 76% dry whole corn and resulted in a 7.2% improvement (P<.05) in G:F (0.208 vs 0.194). No improvement was seen in the HMC diet, indicating that Amaferm’s effect was impacted by corn type. The added performance in the dry corn based diet was seen with no change in carcass composition. |
