Table 1 Variables of cat-subcat Index i1 involved in the model
Original value | Description of the variable content | Recommendation |
|---|---|---|
Cattle | ||
1 | Dairy cow | Remain, but include calves for remounting until heifer |
2 | Beef cattle | Remain |
3 | Veal calves | Remain |
ENV 220 [12] | Calves in igloos | Integrate |
Pigs | ||
4 | Sows, in individual pens | Since farrowing also takes place in groups, it is recommended to change the wording to “sows in farrowing units” |
5 | Sows in groups | Remain |
6 | Fattening pigs | Remain |
Weaner piglets | Currently missing, suggested to add if not covered by the fattening pigs as a worst-case scenario | |
Poultry | ||
7–10 | Laying hens in battery cages | This housing system has been permitted throughout the EU since 2012; recommend to shorten to one variable “Laying hens in enriched cages” |
11 | Laying hens in free range with litter floor (partly litter floor, partly slatted) | Delete the supplement in brackets since the slatted floor in hen husbandry seems to be outdated |
12 | Broilers in free range with litter floor | Remain |
13 | Laying hens in free range with grating floor (aviary system) | Change order and list before broilers |
14 | Parent broilers in free range with granting floor | Remain |
15 | Parent broilers in rearing with granting floor | Remain |
16 | Turkeys in free range with litter floor | Remain |
17 | Ducks in free range with litter floor | Remain |
18 | Geese in free range with litter floor | Remain |
Quails and ostriches | Should be checked if relevant | |
19 | Manure storage—wet | Remain |
20 | Manure storage—wet | Remain |
Other species | ||
Horses | Not considered, because of missing data. Relevance of insecticide applications is unclear because of an increase of vector-borne diseases, but there are limited data if prevention is performed via chemical or physical vector elimination [16,17,18,19,20] | |
Goat | Should be checked if relevant | |
Sheep | Should be checked if relevant | |
Rabbit | Integrate the decision of the BPC WG ENV IV 2020 that for rabbits, the default values from animal category 10 should be used; however, the amount of nitrogen produced per animal per day should be replaced by the default value for ducks | |
ENV 207 [12] | Mink | Integrate |
Farmed game | No worst-case scenario expected, but should be checked for the sake of completeness | |
Insects | No worst-case scenario expected, but should be checked for the sake of completeness | |
