Backyard Livestock and Poultry Survey 2010-2016 - Philippines

Abstract
---------------------------

The Republic of the Philippines is making great efforts to develop agriculture at a pace necessary to meet the food requirements of the fast growing population. It has become necessary to use current agricultural statistics that will help present an accurate picture of the country's food situation. Especially important, is the expected supply and consumption requirements of the people, particularly of meat products. The Backyard Livestock and Poultry Survey (BLPS) seek to provide such information.

The data to be obtained from this survey would not only be important from the point of view of the national economy but also from that of the farmer. The government should have available accurate information with which to anchor its major agricultural policy decisions, of which the farmers are the ultimate beneficiaries. For instance, a decision on whether to import or export livestock and poultry products has its effects not only on the national economy but also on the individual farmer. Such national decision will directly affect the raising and trading decisions of livestock and poultry raisers in the country.

The BLPS is one of the four major surveys for livestock and poultry. This survey aims to generate primary data on inventory/population, and supply and disposition of animals from backyard farms (small holders). Specifically, the survey gears to generate information on the following: Livestock and Poultry inventory and production; and Current egg production for ducks and chicken.

Moreover, BLPS shall also aid the policy makers in generating sound policy decision on the improvement of backyard farms for the welfare of the farmers.

The survey covered all backyard farms. Backyard Farm refers to a farm or household whether farming or non-farming operated by a farmer/household that raises at least one of the following:

1. Livestock
· Less than 21 heads of adult and zero head of young
· Less than 41 heads of young animals
· Less than 10 heads of adult and 22 heads of young

2. Poultry
· Less than 500 layers, or 1,000 broilers
· Less than 100 layers and 100 broilers if raised in combination
· Less than 100 head of duck regardless of age

A backyard farm is categorized by its household classification. There are two (2) household classification. These are farming households and non-farming households.

The farming household is any household in which a member operates an agricultural land, either solely or jointly with other members, and the aggregate area operated by the operator-members of such household qualifies to be called a farm. The non-farming household is any household in which a member operates an agricultural land, either solely or jointly with other members, and the aggregate area operated by the operator-members of such household does not qualify as a farm.

Sample survey data [ssd]

Sampling procedure
---------------------------

The BLPS uses the Palay and Corn Production Survey (PCPS) frame. There are four (4) replicates of the PCPS but the BLPS covers only one (1) replicate, consisting of one barangay per replicate. The BLPS employs a two-stage stratified sampling with the barangay as the primary sampling unit (PSU) and the household as the secondary sampling unit (SSU). Sample selection is done as follows.

First Stage (Primary) Sampling Unit Selection
Selection of sample barangays is based on pre-determined classification of provinces. For provinces whose major crop is either palay or corn, ten (10) sample barangays are covered. For provinces where both palay and corn are the major crops (called overlap provinces), five (5) barangays are drawn from palay barangays and another five (5) barangays from corn barangays. Finally, for other provinces (those whose major crop grown is neither palay nor corn), only five (5) sample barangays are drawn.

Second Stage (Secondary) Sampling Unit Selection
All PCPS sample farming households in the BLPS sample barangay are covered. To represent the non-farming group in each sample barangay, additional five (5) non-farming households are selected through the right coverage approach with a defined starting point and random start.

Response rate refers to the ratio of sample households who responded to the survey to the total number of sample households, expressed as a percentage. The response rate for January, 2016 Round is above 85%.

摘要
---------------------------
菲律宾共和国正不遗余力地发展农业，以确保满足快速增长的人口对食物的需求。为此，有必要利用当前的农业统计数据，以准确反映国家的粮食状况。特别是，预测的人们的供应和消费需求，尤其是肉类产品，显得尤为重要。后院畜牧业和家禽调查（BLPS）旨在提供此类信息。

从此次调查中获取的数据不仅对国民经济具有重要意义，对农民而言亦然。政府应拥有准确的信息，以便作为其主要农业政策决策的依据，而农民则是最终的受益者。例如，关于是否进口或出口牲畜和家禽产品的决策，不仅影响国民经济，也对个体农民产生影响。此类国家决策将直接影响国内牲畜和家禽饲养者的饲养和贸易决策。

BLPS是四大主要畜牧业和家禽调查之一。此次调查旨在收集关于后院农场（小农）的库存/人口、以及动物的供应和处置的原始数据。具体而言，调查旨在收集以下信息：牲畜和家禽的库存和生产；以及鸭子和鸡的当前蛋产量。

此外，BLPS还将协助政策制定者制定改善后院农场以促进农民福祉的合理政策。

调查范围
---------------------------
本次调查涵盖了所有后院农场。后院农场是指由农民/家庭经营，不论是否从事农业，至少饲养以下之一的农场或家庭：

1. 牲畜
· 成年牲畜少于21头，幼畜为零头
· 幼畜少于41头
· 成年牲畜少于10头，幼畜为22头

2. 家禽
· 层舍少于500只，或肉鸡少于1,000只
· 如果混合饲养，层舍和肉鸡均少于100只
· 鸭子无论年龄，头数少于100只

后院农场根据其家庭分类进行分类。有两种（2）家庭分类。这些是农业家庭和非农业家庭。

农业家庭是指任何家庭成员单独或与他人共同经营农业土地的家庭，该家庭操作者的经营面积总和有资格被称为农场。非农业家庭是指任何家庭成员单独或与他人共同经营农业土地的家庭，该家庭操作者的经营面积总和不足以被称为农场。

数据类型

样本调查数据 [ssd]

抽样程序
---------------------------
BLPS使用Palay和玉米生产调查（PCPS）框架。PCPS有四个（4）重复样本，但BLPS仅覆盖一个（1）重复样本，由每个重复样本的一个村组成。BLPS采用两阶段分层抽样，以村为一级抽样单位（PSU），以户为二级抽样单位（SSU）。样本选择如下。

第一阶段（一级）抽样单位选择
样本村的选择基于事先确定的省份分类。对于主要作物为稻米或玉米的省份，覆盖十个（10）样本村。对于稻米和玉米都是主要作物的省份（称为重叠省份），从稻米村抽取五个（5）村，从玉米村抽取另外五个（5）村。最后，对于其他省份（主要作物既不是稻米也不是玉米的省份），仅抽取五个（5）样本村。

第二阶段（二级）抽样单位选择
BLPS样本村中的所有PCPS样本农业家庭都被覆盖。为了代表每个样本村中的非农业群体，通过定义明确的起始点和随机起始点的方法，额外选择五个（5）非农业家庭。
