The provincial estimate is given as follows:
The regional and national estimates for the ith animal type is obtained by summing up all the estimates for that animal type across all provinces in the region and all provinces across all regions, respectively.
The total for Metro Manila includes observations for all farms located in Metro Manila only. Farms located in the province outside of MM but whose data are gathered from their MM office will be accounted in the province where their farms are located.
For provinces where sampling is employed, (denoted by p), the estimated provincial total is obtained by direct expansion of the farm level observations within a stratum, then aggregating the stratum estimate across all strata; that is
Estimates at the regional and national levels are made up of two components: totals for provinces where complete enumeration is employed (), and estimates for the provinces where sampling is employed (p). Thus, the regional-level estimate is expressed as:
While the national-level estimate is given by the formula:
Estimated total milk production for a province:
Estimated total number of animals per category for a province:
Estimated total milk production in the Philippines:
Estimated total number of animals per category in the Philippines:
The Survey of Animals Slaughtered in Abattoirs and Dressing Plants requires daily recording of slaughter by the meat inspectors assigned in the facility. In the case of accredited facilities, the NMIS Meat Officers in the province or region gather the questionnaires monthly for consolidation and compilation.
The BAS regular personnel, on the other hand, using the prescribed questionnaires gather data from the non-accredited abattoirs and dressing plants in two approaches i) meat inspectors fill up the daily records of slaughter using the questionnaire or ii) gather data from the monthly records of meat inspectors.
The data gathered from the abattoirs and dressing plants are processed using MASLink, a customized data processing system developed using the IMPS software. Processing is done at the Regional Operations Centers (ROCs). Prior to encoding, the accomplished questionnaires are manually edited for validity and consistency. The data files also undergo validation using an editing program where data items are subjected to a set of validation criteria such as consistency check, range check and acceptability. The clean data file will now serve as input to the tabulation programs to be able to generate the output tables.
BAS personnel (point person for the activity) summarizes the data into a quarterly total with monthly breakdown of animals slaughtered/dressed using MASA Form 2. (Quarterly Report Form). The MASA Form 2 is submitted to BAS Central Office, copy furnished Regional Office, for regional and national consolidation.
