Livestock population surveys
Surveys on the number of pigs
Luxembourg conducts two pig surveys per year - in May and December. Each year, the surveys conducted in May, and every three years those conducted in December are integrated livestock censuses.
These surveys are carried out as full-scale surveys each year in May and every three years in December. The last full-scale surveys were conducted in Luxembourg on 1.12.1999 and 15.05.2000. 98.3% of the total pig population is covered by the sample surveys. They cover 275 holdings, representing 61.25 % of the total number of pig holdings.
A sample is drawn on the basis of the results of the full-scale survey carried out on 1 December every three years. The tables showing the number of livestock held are used to produce strata with the total number of holders and animals in a given stratum. The percentage of livestock in a stratum is placed in relation to the total number of livestock in all strata; the percentages obtained are applied to the number of holders in the individual strata in order to establish the necessary number of holders in these strata; the computer then seeks the required holders by random selection and calculates the number of animals held by these for the individual strata. The calculated livestock populations are then compared for each stratum with the total number of animals in these strata in order to obtain the corresponding coefficients. These coefficients are applied in the sample surveys in the two years between two full-scale surveys in order to raise the results to the total population level; all holdings with over 50 pigs are covered.
The definitions are the same as for the structure survey. The full-scale survey in May is identical with this survey.
The surveys are not restricted to selected regions.
The surveys are conducted by enumerators interviewing farmers (in full-scale surveys) or as written enquiries in the case of sample surveys. Responses are obtained from 97.5% of those questioned. The communal administrations do the interviewing for full-scale surveys; STATEC is responsible for conducting sample surveys. The results of the full-scale surveys are checked and evaluated by STATEC.
In order to incorporate missing information (non-response) in the results processing, a coefficient is calculated on the basis of the full-scale surveys of May of year n and year n-1, which is applied to the results of the full-scale survey or sample survey in December of the holding of year n-1 in order to estimate the results for December of year n.
Luxembourg intends in the medium term (by 2005) to replace statistical surveys of the pig population by the use of administrative data. The data source used in future could be SANITEL (an electronic registration system). At the moment, however, this system is only available for cattle.
Surveys on the number of cattle
Luxembourg conducts two cattle surveys per year - in May and December. Each year, the surveys conducted in May, and every three years those conducted in December are integrated livestock censuses.
These surveys are carried out as full-scale surveys each year in May and every three years in December. The last full-scale surveys were conducted in Luxembourg on 1.12.1999 and 15.05.2000. 64.6% of the total cattle population is covered by the sample surveys. They cover 780 holdings, representing 41.96% of the total number of cattle holdings.
A sample is drawn on the basis of the results of the full-scale survey carried out on 1 December every three years. The tables showing the number of livestock held are used to produce strata with the total number of holders and animals in a given stratum.

Surveys on the number of sheep and goats
Luxembourg conducts two surveys per year on the sheep population and one survey on the goat population. The surveys are carried out in May (sheep) and December (together for both sheep and goats). The annual May survey and the December survey held every three years are integrated livestock surveys.
These surveys are conducted as full-scale surveys.
They are not restricted to selected regions.
The surveys are carried out by enumerators interviewing farmers. In two out of three years, the December surveys are implemented as written surveys. The communal administrations are responsible for the interviewing, while STATEC is responsible for checking and evaluation. STATEC is directly responsible for the implementation of the written survey held every two years.

Statistics on slaughterings
Luxembourg keeps monthly statistics of the number and slaughter weight of livestock slaughtered in abattoirs whose meat is suitable for human consumption, for all pigs, calves, heifers, cows, bulls and bullocks.
Availability of monthly data on slaughterings
Weight
The Service d`Economie Rurale, a State service answerable to the Minister of Agriculture has a Division for Agricultural Statistics and Economic Accounts for Agriculture, whose responsibilities include producing statistics on agricultural output.
All slaughterings of domestic cattle and pigs in Luxembourg are recorded constantly (weekly or monthly) by the "Cheptel et Viandes", section of the Service d`Economie Rurale at abattoirs and private slaughter sites (tueries privées). The data collected comprise: number of livestock slaughtered, sex and age of the animals by category. The different categories are, for cattle: cows, female calves, bulls, bullocks; for pigs: fattening pigs, sows and boars, piglets. The classification is based on the Community classification system.
The data are processed by the "Cheptel et Viandes" section and passed on to the Agricultural Statistics Division. They are forwarded by the abattoirs to the Service d'Economie Rurale" by post and are generally available 6 weeks after the end of the survey month and can be passed on to external bodies, e.g. Eurostat. Slaughter data have been forwarded electronically since 1.1.2000, at least by abattoirs. Work on the use of electronic reporting by abattoirs for statistical purposes is continuing. The slaughter statistics are expected to be switched to this data source in the summer of 2001. More reports are expected to be submitted and the statistics improved as a result. All slaughterings (of domestic animals and those imported for slaughtering) are covered by a uniform system: the slaughterings of horses, sheep and goats, too, are covered by this system. Data on the slaughterings of imported animals for slaughter are provided by the veterinary authority. These data do not contain information on the category and slaughter weight.
House slaughterings are covered by the full-scale survey of livestock populations on 1 December every three years. The data collected are: number, category and total slaughter weight. The data thus obtained are used unchanged for three years for the quantity statistics and EAA. House slaughterings make up a small proportion (about 2%) of the total number of slaughterings.
Data on external trade in live animals
Exports of live animals within the single market are collected by the veterinary authority under the health provisions and forwarded to the Service d`Economie Rurale, Agricultural Statistics Division. The data are broken down by livestock for slaughter and breeding and productive livestock, but not according to category and class (for animals for slaughter). They are compiled by the Service d'Economie Rurale, Agricultural Statistics Division, broken down by category and class and expressed in slaughter weight. The breakdown of the data by category and class and the establishment of the total slaughter weight is obtained by raising the results of a survey of the main livestock export trading companies.
A survey of live animal imports, broken down by breeding and productive livestock/livestock for slaughter, is conducted by the veterinary authority and forwarded to the Service d`Economie Rurale, Agricultural Statistics Division.
Poultry statistics
The poultry population is covered by an annual full-scale survey held on 15 May and based on the structure survey. The veterinary authority compiles statistics of the poultry slaughtered in officially recognised poultry abattoirs. A survey of domestic slaughterings of poultry is carried out every three years in December. No breakdown is made by category for existing data on poultry slaughterings. No monthly slaughtering data or forecasts on poultry meat output are available. It is not possible to estimate the poultry population on the basis of eggs for hatching since there are currently no hatcheries in Luxembourg.
