3.1. Data description | |||
Statistics on eggs for hatching and farmyard poultry chicks are collected under (market) Regulation (EC) No 617/2008. They are the earliest available information to foresee production of poultry meat and eggs, as the numbers of chicks of various utilities placed in the farms of each Member State, i.e. the number of chicks placed by the hatcheries of this Member State increased by the net import of chicks. The survey of poultry in Bulgaria was introduced in 2004 by the Ministry of Agriculture and Food and covers the following species: chickens, turkeys, ducks, geese, quail, ostrich and guinea fowl as well as the production of their products - eggs and poultry for slaughter. Eurostat uses the data for foreign trade of chicks for Bulgaria directly from the Comext database. Comext is filled and loaded by the responsible institution for foreign trade statistics in Bulgaria - NSI. |
|||
3.1.1. Model description | |||
Monthly exhaustive survey All hatcheries that placed more than 1000 eggs per year are interviewed. Customs declarations from all customs offices are entered in the Bulgarian Integrated Customs Information System. Monthly, based on a bilateral agreement with Customs Agency, NSI receives primary data necessary for the compilation of foreign trade statistics. Intrastat declarations are entered in the information system "Intrastat" of NRA. Monthly, according to the Instruction for information exchange between NSI and the NRA developed in implementation of the Law on Statistics of Intra-Community Trade in goods, NSI receives primary file with records of all Intrastat declarations |
|||

3.6.1. Source of the list of statistical units (AH) | |||
Statistical survey - Poultry breeding in Bulgaria Registry of Bulgarian food safety agensy The list of hatcheries has been compiled on the basis of a statistical survey of poultry in Bulgaria and is periodically updated with information from the register of the hatcheries maintained by the Bulgarian food safety agency (BFSA) |

The list of statistical units is based on a statistical survey - Poultry breeding in Bulgaria, conducted every year by the Agrostatistics department.

We also use the Register of the Bulgarian food safety agency to update the list of statistical units. |

Calendar month |
|||
5.2. Reference period (TC) | |||
Theoretically, the reference period for the information on international trade in goods transactions should be the calendar month of export or import of the goods. However, in practice the reference period for extra-EU trade is generally the calendar month during which the customs declaration is accepted by customs authorities. The reference period for intra-EU trade may be adapted in case of sales or purchases to the calendar month during which the VAT on the intra-EU supplies or acquisitions becomes chargeable. The chargeable event relates to the issue date of the invoice. |
