Livestock surveys
Surveys on the number of pigs
Number of the pig surveys
In Slovenia 3 surveys on the number of pigs are carried out per year.
Months in which pig surveys are carried out
April, August and December
Separate / integrated pig surveys
All the surveys are separate pig surveys.
Sample / full pig surveys
In enterprises in co-operatives full surveys are carried out.
On private farms sample surveys are carried out.
The average sampling error in the recent years
2.8 %
Last full survey
The last full survey on the number of pigs was carried out in June 2000 within the agricultural census.
Sampling method
In 1999 the sample design was stratified simple random sampling. Stratification was based on the number of pigs. The frame was divided into 4 strata, namely:
Farms from stratum 4 were selected with certainty. In strata 1, 2 and 3 allocation was defined optimal by Neyman according to results from the 1998 survey. Afterwards farms were selected at random.
Percentage of the total pig population recorded by the sample survey
By the sample surveys 35 % of pig population is recorded.
Number of holdings recorded by the sample and percentage of the total number of the holdings breeding pigs
By the sample surveys 8000 private farms are recorded which is about 12 % of all private farms breeding pigs.
Surveys in selected regions
No.
Method used for estimating the pig population not recorded by the sample surveys
All pig population is included into sample frame.
Average response rate
The average response rate is above 70 %.
Treatment of non response
Due to unequal probability for selection and non-response, obtained data are weighted. Item non-response is imputed.
Mode of data collection
Data on the number of pigs are obtained by written inquiries. Non-response is followed up by phone.
Institution responsible for the survey
Statistical Office of the Republic of Slovenia
Use of administrative sources instead of pig surveys in the next 5 years
No.

Number of the cattle surveys

Sampling method
In 199 the sample design was stratified simple random sampling. Stratification was based on the number of sheep/goats. The frame was divided into 2 strata, namely:
Farms from stratum 2 were selected with certainty. In stratum of small farms (stratum 1) farms were selected at random with the sample share of 10.0%.
Percentage of the total sheep and goat populations recorded by the sample survey
By the sample surveys 65 % of sheep population and 44 % of goat population are recorded.

Slaughtering data
Availability of monthly data on slaughterings
Weight(a)
1Monthly data on number of slaughtered animals and on slaughterweight are available for slaughterhouses only.
Procedure used for recording slaughtering data
Data on slaughter are collected monthly from all slaughterhouses in Slovenia by means of a postal survey. Data are collected by Statistical Office of the Republic of Slovenia. Data are available in three weeks after the reference month. Data on slaughter on private farms are estimated once a year.
Foreign trade data for live animals
Procedure used for recording foreign trade data
The source of data for external trade statistics are customs declarations. In the beginning of 1996 the Single Administrative Document (SAD) was introduced. Data from customs declarations are reported to the Statistical Office by Customs Administration of the Republic of Slovenia monthly on electronic media. Data refer to the last cumulative period and contain both new declarations for the last reporting month and all declarations for previous months, including changes since last reporting.
Statistical Office completes data from customs declarations with the additional data and classifications, required for statistical survey. At this process the recommendations of the Statistical Office of the United Nations are taken into consideration from the aspect of data coverage as well as other methodological elements. Combined Nomenclature is used. Data are available in 2 months after the reference month.
Production forecasts (gross domestic production)
Slovenia has not introduced the production forecast yet.
Poultry statistics
Information available in the field of poultry statistics
Data on slaughter of poultry are included in the monthly reports on slaughter of slaughterhouses. Within this survey the data on number and weight of dressed carcasses of slaughtered broilers, hens, turkeys and other poultry (ducks, geese) are observed.
Till now there are no forecasts on poultry meat production.
Data on number of laying hens as well as egg production are obtained from agricultural enterprises and co-operatives with the regular annual census.
Data on number of laying hens and eggs production on private farms are currently estimated on the basis of results of Sample Farm Structure Survey 1997. By the estimation also data of Veterinary Inspection Service are used.
In December 2000 a pilot survey on number of poultry on private farms was carried out but results are not available so far.
