Data set on the Estimate the emission from Cattle rearing from the Landmark University Farm.

Data set involve sub Categories of cattle in which estimation of feed Intake or Gross Energy (GE) Intake for Cattle Animal performance and diet data are required to estimate feed intake, which is the amount of energy (Mega Joules (MJ/day) an animal needs for maintenance and for activities, growth, lactation, work, and pregnancy. The method for Estimating methane emission from Enteric Fermentation using tier 2 methodology requires three basic steps: Step 1: Divide the livestock population into subcategory and characterize each sub-category (matured cow, Growing Heifers, Young Female, Mature male (Oxen), Breeding bull and Growing Male). Step 2: Estimate feed intake (gross energy) required for calculation of methane emission factor. Step 3: Calculate methane emission factors for each subcategory in terms of kilograms of methane per animal per year. Step 4: Multiply the subcategory emission factors by the subcategory populations to estimate subcategory emission Step 5: Sum-up the sub-category emission to get total emission from cattle
