Requirement functions are specified that determine: | Requirement functions are specified that determine: | ||
+ | |||
+ | * ENNE Net energy for ruminants as sum of | ||
+ | * NEL net energy for lactation (cows, ewes, goats) | ||
+ | * NEM net energy for maintenance (cows, calves, bulls, heifers, ewes, goats) | ||
+ | * NEA net energy for activity (cows, calves, bulls, heifers, ewes, goats) | ||

+ | * ENMP Net energy pigs | ||
+ | * CRPR crude protein (all categories) and LISI lysine aminoacid (sows, poultry) | ||
+ | * DRMA dry matter (all categories with min and max requirements) | ||
+ | * Various fiber measures (irrelevant for COCO2) | ||
+ | There are three main sources for these functions: | ||
+ | * IPCC 2006 guidelines for the estimation of emissions ([[http:// | ||
+ | * Kirchgessner Tierernährng, | ||
+ | * CAPRI working paper 97-12 ([[http:// | ||
+ | |||
+ | These functions are one the one hand quite complex. They are composed of various parts that finally give the requirements, | ||
+ | |||
+ | As a starting point, the daily growth from COCO is forced into the range defined in // | ||
+ | |||
+ | \begin{align} | ||
+ | \begin{split} | ||
+ | & | ||
+ | &= min [DAILY_{up}^{HEIF}, | ||
+ | \end{split} | ||
+ | \end{align} | ||
+ | |||
+ | The daily increase is then used to determine the process length (rearrangement of equation below with empty days EDAYS = 0) | ||
+ | |||
+ | \begin{align} | ||
+ | \begin{split} | ||
+ | & | ||
+ | &= min [DAYS_{up}^{HEIF}, | ||
+ | & \quad (BEEF_r^{HEIF}/ | ||
+ | \end{split} | ||
+ | \end{align} | ||
+ | |||
+ | The daily increase and process length may be conbined to estimate the mean live weight, | ||
+ | |||
+ | \begin{equation} | ||
+ | meanWgt_r^{HEIF}=startWgt_{HEIF}+\frac {dailyIncrease_r^{HEIF}\cdot fatngdays_r^{HEIF}} 2 | ||
+ | \end{equation} | ||
+ | |||
+ | which in turn is the last information to estimate energy requirements for maintenance according to the IPCC guidelines: | ||
+ | |||
+ | \begin{equation} | ||
+ | NEM_r^{HEIF}=(meanWgt_{HEIF})^{0.75}\cdot 0.322 \cdot fatngdays_r^{HEIF} | ||
+ | \end{equation} | ||
+ | |||
+ | Other energy requirements (for growth and activity) are calculated in a similar fashion as well as those for other animals. Important aspects to note are | ||
+ | |||
+ | * Fixed bounds for DAYS and DAILY ensure reasonable requirements, | ||
+ | * Regional coefficients are derived from the MS level information | ||
+ | |||

+ | |||
+ | With animal requirements specified the results of COCO1 for grass, other fodder and as a last resort cereals might be revised in terms of losses on farm to achieve an acceptable relationship of energy and protein requirements of total herds compared to the intake with feed. For gras and other fodder on arable land the contents may be adjusted in certain limits as well. The corrections do not eliminate the typical oversupply of nutrients compared to the requirements based on the literature, but they should give reasonable starting values for the feed allocation addressed in module CAPREG. | ||
+ | |||
+ | ===Compare COCO1 results with UNFCCC and compute correction factors in coco2_lulufc_carbon=== | ||
+ | |||
+ | In COCO1, an assignment of LULUCF effects (totals and per ha) has taken place, mostly relying on IPCC coefficients. These assignments are compared in coco2_lulucf_carbon with the reportings from EU MS to UNFCCC. For forestry and any transitions involving forestry, the standard IPCC reporting appears rather coarse, as it implies, for example, that management of forest land remaining forest has zero carbon effects. By contrast most EU countries report that there is still a considerable gain in biomass from forest management because the forests have not yet achieved a stable state (as implied by IPCC standard methodology). | ||
+ | |||
+ | To pick up the detailed knowledge of management practices, disturbances, | ||
+ | |||
+ | ===Complete prices for vegetable oil in coco2_oil_price=== | ||
+ | |||
+ | The EU prices for vegetable oils relevant for biofuel processing functions are assigned using prices from a USDA source. These assignments refer to prices at the wholesale level (relevant for the processing industry), not to consumer prices which have been determined previously. | ||
+ | |||
+ | After this last include file the completions in module COCO2 are finished and the main output file (coco2_output.gdx) is unloaded. This file is loaded in subsequent modules (main use in CAPREG, but also in CAPTRD for nowcasting and in CAPMOD for update of LULUCF coefficients). | ||
