Every year, zookeepers at ZSL London Zoo train and coax more than 17,000 animals into stepping on the scales to be weighed and measured.

每一年，倫敦動(dòng)物園的工作人員都得費(fèi)盡心機(jī)讓園里17000種動(dòng)物走上磅秤稱體重，以及接受各種測(cè)量。

The statistics are needed to ensure the animals are healthy — and to make sure they're not enjoying the easy-to-come-by food in captivity a little too much. Measurements can also help determine if an animal is pregnant, which can be vital information for conservation work of endangered species.

獲得這些數(shù)據(jù)的目的是為了確保動(dòng)物身體健康，同時(shí)也為了防止他們?cè)陲曫B(yǎng)過(guò)程中吃下過(guò)多的食物。測(cè)量體重也可以判斷動(dòng)物是否懷孕，這些都為保護(hù)瀕危物種提供了重要信息。

The information is recorded in the Zoological Information Management System (ZIMS) and shared with zoos around the world. The annual event is well-documented — and judging by these photos, justifiably so.

這些信息都會(huì)被記錄在動(dòng)物信息管理系統(tǒng)（ZIMS）里，并和全世界的動(dòng)物園共享。每一年的體重測(cè)量會(huì)實(shí)況，都會(huì)以各種形式記錄下來(lái)?？纯聪旅孢@些照片，的確是這樣。
