Nebraska Beef Cattle Reports
The purpose of beef cattle and beef product research at the University of Nebraska-Lincoln is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc.) of beef production.
Dedicated in memory of Dr. Terry Klopfenstein (March 10, 1939-April 30, 2021), Professor Emeritus, Animal Science Department, University of Nebraska-Lincoln.

Nebraska Beef Cattle Reports
An experiment was conducted to evaluate the impact of biochar and time on manure nutrient retention. Pans were used to simulate feedlot pens with 10 replications per treatment. Biochar was included at 0, 5, or 10% of manure dry matter with 30 and 60 day durations to evaluate pan contents over time. There was a 13- percentage unit increase in organic matter losses from day 30 to 60 for pans without biochar, and a 3- percentage unit increase for pans containing biochar. The least nitrogen loss was measured on the pans without biochar harvested at 30 days. Pans harvested at …

A study was conducted to evaluate the impact of feeding biochar growing diets on cattle performance and methane and carbon dioxide emissions. Two treatments were evaluated, a forage- based control diet without biochar and a diet with biochar included at 0.8% of the diet dry matter, replacing ! ne ground corn in the supplement. Pens of cattle were rotated through a two- sided emissions barn (2 pens evaluated simultaneously) to capture CH4 and CO2 production. " ere were no statistical differences in performance or gas emissions for steers fed a biochar supplemented diet compared to control. Numerically, biochar supplemented steers …

Two metabolism studies were conducted to evaluate the effects of biochar (0, 0.8, or 3% of diet dry matter) on digestibility and methane production in growing and finishing diets. Intake was not affected by biochar inclusion in the growing diet and increased with 0.8% biochar inclusion in the finishing study. Digestibility tended to increase quadratically with biochar inclusion in the growing study while digestibility tended to linearly decrease with biochar inclusion in the finishing study. Methane production (g/d) decreased 10.7% in the growing study and 9.9% in the finishing study with 0.8% biochar compared to no biochar. Methane production was …
