Effect of Micro-Aid\u3csup\u3e®\u3c/sup\u3e Supplementation on Nitrogen Losses from Manure

A 2x2 factorial designed experiment was used to study the effects of Micro-Aid and time on OM and N losses from manure, in a simulated feedlot pen setting. Manure was collected from cattle on a common diet, except for the addition of 1 g Micro-Aid /steer daily. Losses of OM were greater at 60 d than 30 d, and greater for control than Micro-Aid. Nitrogen losses at d 30 were similar between treatments but control pans had greater N losses at d 60. Feeding Micro-Aid to cattle may inhibit N volatilization from manure, enhancing the fertilizer value of manure

Effect on Performance and Nutrient Mass Balance of Feeding Micro-Aid in Wet Distillers Grains Plus Solubles Diets

Finishing cattle performance and mass balance were evaluated when Micro- Aid® was fed in diets containing wet distillers grains plus solubles (WDGS). There was no difference in performance and carcass characteristics between treatments. In a WINTER experiment, cattle fed Micro-Aid had a greater amount of OM and DM removedin manure. Micro-Aid in the diet increased the amount of manure N and decreased N losses in the WINTER. There was no difference in N excreted in manure or lost via volatilization in the SUMMER experiment

Effect of Feeding Greater Amounts of Calcium Oxide Treated Corn Stover and Micro-Aid® on Performance and Nutrient Mass Balance

Feedlot performance and mass balance were evaluated on steers fed either 5% untreated corn stover (CON), 20% untreated corn stover (NONTRT), or 20% calcium oxide (CaO) treated corn stover (TRT) when fed with or without saponins (Micro-Aid) in a 3x2 factorial. In both WINTER and SUMMER experiments, ADG, F:G and HCW were improved (P \u3c 0.01) in CON and TRT fed steers compared to NONTRT fed steers. Micro-Aid fed steers had slightly greater ADG and DMI in the SUMMER. Manure% nitrogen (N) was greatest when NONTRT and TRT were fed compared to steers on CON diet. However, neither diet nor Micro-Aid influenced manure N amounts or N losses across both seasons
