Ruminant Livestock

Using the Livestock Analysis Model: Continued

Results

Exhibit 5 shows the results screen of the model. The screen is divided into five sections. The first section shows that the production targets were met. Additionally, the methane emissions estimate is shown.

The second section shows the results by sector. As shown in this example, all the milk is produced in the milk sector. This sector also produces some amount of meat, principally from the cows that are culled. The remainder of the meat is produced in the meat sector. The methane emissions are also reported by sector in the last row. Note that the draft production is zero, resulting in a draft emissions of zero.

The third section of the results shows the population and production in each sector in detail. Each animal type is listed. In this example, the Milk Sector has 18.6 million head, while the Meat Sector has 85.3 million head. Because no draft power is produced, the draft sector has no herd.

The fourth section of the report shows emissions per unit of product produced. The emissions from each of the milk sectors is divided by the production in each sector to get the estimate for each. Similar analyses are done to estimate emissions per unit of draft power and emissions per unit of meat produced.

The final section of the results shows methane emissions by animal type within each sector. In this example, the emissions from the adult cows account for the majority of the total emissions.
