1 This publication presents quarterly statistics on livestock and poultry slaughterings, meat production, receivals of taxable wool by brokers and dealers, exports of live sheep and cattle and exports of fresh, chilled, frozen and processed meat.
2 Also presented are limited quarterly and annual data relating to red meat slaughterings and links to whole milk intake and market milk sales. Prior to the September 2011 edition, more comprehensive data relating to livestock slaughter and red meat production were included in this product. From September 2011 onwards these data continue to be available on a monthly basis in Livestock and Meat, Australia (cat. no. 7218.0.55.001).
3 Data in this publication have been revised where necessary and as a consequence may not agree with similar data shown in previous publications.
4 Where figures have been rounded, discrepancies may occur between sums of the component items and totals.
5 Unless otherwise indicated, Australian totals include data for all states/territories.
LIVESTOCK SLAUGHTERINGS AND MEAT PRODUCTION
6 Statistics for poultry slaughterings and chicken meat produced have been compiled from quarterly returns supplied by commercial poultry slaughtering establishments and comprise boilers, fryers and roasters. Many small producers are excluded from the collection; however, the statistics represent a high level of coverage.
7 A coverage exercise has been undertaken to review the quality of the sampling frame for the Poultry and Game Birds Collection. While the updated poultry estimates are reflective of the improved sampling frame, the frame updates have had a small impact on the associated time series.
8 Care should be taken when using this information as the data only relate to slaughterings for human consumption and do not include animals condemned, slaughtered for pet food or those killed for boiling down.
9 Chicken meat is shown in dressed weight of whole birds, pieces and giblets.
10 Details about unpublished slaughterings and meat production statistics can be found in the Livestock Slaughtering Collection brief on the Australian Bureau of Statistics (ABS) website and also are available on request. Inquiries should be made to the National Information and Referral Service on 1300 135 070.
EXPORTS OF FRESH, CHILLED, FROZEN AND PROCESSED MEAT
11 From September Quarter 2012 onwards, changes to the methodology for compiling exports data in Livestock Products, Australia (cat. no. 7215.0) were implemented. The changes are as a result of a shift from using AHECC (Australian Harmonised Export Commodity Classification) codes to SITC (Standard International Trade Classification) codes. The methodological change to using SITC codes is aimed at providing a more stable basis for data comparability over time. SITC is the ABS preferred classification for published trade statistics, due to less variability in code definitions. The effect of the change to SITC classification is to produce a series break in the time series for exports. Many of the time series in releases prior to September Quarter 2012 will not align with time series published since. However, the exports time series have been backcast to the beginning of the series in March Quarter 1988 in order to provide a consistent basis for comparison.
12 International trade statistics are compiled by the ABS from information submitted to the Australian Customs Service by exporters and importers or their agents. Factors are applied to beef, veal, mutton and lamb bone-out figures to calculate a derived bone-in carcass weight. The derived bone-in carcass weights are then added to bone-in figures to calculate total exports in carcass weight. The factor for beef and veal is 1.5 and for mutton and lamb, 2.0. This information is sourced from the Australian Department of Agriculture, Fisheries and Forestry.
13 Beef also includes buffalo meat.
14 Bacon and ham shown is the cured carcass weight of smoked or cooked bacon and ham. It also includes the stated net weight of packs of canned bacon and ham.
15 Details of the classification changes referred to in Paragraph 11 for the time seriesTable 5 - "Exports of Fresh, Chilled, Frozen and Processed Meat: Original (tonnes) can be found in the I-Note in the September Quarter 2012 release of this publication.
LIVE SHEEP AND CATTLE EXPORTS
16 Cattle exported for breeding are excluded, but the number of sheep exports includes both breeding and non-breeding stock. This is a consequence of changes in international trade classifications from 1 January 2012 which no longer provide separate categories for breeding and non-breeding sheep.
17 The unit value is obtained by dividing the gross value by the number of animals exported.
18 The graphs of livestock exports present quarterly original estimates for the last four years for live sheep and cattle, with exports by major country of destination shown for the last year.
19 Details of the classification changes for the time series Table 6 - "Exports of Live Sheep and Cattle: Original (tonnes) in the September Quarter 2012 release can be found in the I-Note in the September Quarter 2012 release of this publication.
20 Wool receivals refers to the amount of taxable wool received by brokers and purchased by dealers from wool producers. It excludes wool received by brokers on which tax has already been paid by other dealers (private buyers) or brokers.
21 From the September quarter 2010, inclusive, an updated sampling frame was introduced in respect of the Wool Receivals, Purchases and Sales collection. The impact of this change on associated time series is negligible.
22 Data are based on the state in which wool has been received, and do not necessarily reflect the production of wool in that state.
23 Seasonal adjustment is a means of removing the estimated effects of normal seasonal variation from the series so that the effects of other influences can be more clearly recognised.
24 In the seasonal adjustment of the livestock estimates, account has been taken of both normal seasonal factors and ‘trading day’ effects, where significant. Seasonal adjustment does not remove from the series the effect of irregular influences (e.g. abnormal weather, industrial disputes).
25 The state component series has been seasonally adjusted independently. Therefore, the adjusted components may not add to the Australian group totals.
26 In this publication, the seasonally adjusted estimates are produced by the concurrent seasonal adjustment method which takes account of the latest available original estimates. This method improves the estimation of seasonal factors and, therefore, the seasonally adjusted and trend estimates for the current and previous months. As a result of this improvement, revisions to the seasonally adjusted and trend estimates will be observed for recent periods. A more detailed review is conducted annually prior to the September release, using data up to and including the August release.

28 From September 2007, improved methods of producing seasonally adjusted estimates, focused on the application of Autoregressive Integrated Moving Average (ARIMA) modelling techniques, were implemented. The ARIMA modelling technique can be used to extend original estimates beyond the end of a time series.
29 For further information on ARIMA modelling, see the feature article 'Use of ARIMA modelling to reduce revisions' in Australian Economic Indicators, Oct 2004 (cat. no 1350.0).
30 The graphs of livestock slaughtered, meat production and livestock products present quarterly trend estimates for at least the last five years for the major commodities. These graphs highlight the major movements in the estimates over that period.
31 A trend estimate is obtained by reducing the irregular component in the seasonally adjusted series. For quarterly data, trend estimates are derived by applying a 7-term Henderson moving average to the seasonally adjusted series. Revisions of trend estimates will also occur with revisions to the original data and re-estimation of seasonal factors.
32 The state component series has been adjusted independently. Therefore, the adjusted components may not add to the Australian group totals.
