이 연구는 어리장 형태와 계절이 출하환경 및 폐사율에 미치는 영향을 조사하여 출하 중 폐사에 의한 경제적 손실을 예방하고 관련 시설 개선을 위한 정책적 자료를 확보하기 위해 수행하였다. 관리실태는 출하관리환경이 다른 2계열 업체의 관리대장을 입수하여 1, 4, 8, 10월 첫째주 1주일분에 대해 적재중량, 수송밀도, 수송 및 계류시간, 폐사율 등을 분석


The current study was conducted to investigate the effects of types of crate and season on transport condition and mortality, and ultimately to identify the best practice for reducing economic lose. Total loading weight, stocking density, transport and lairage times and mortality were surveyed from the management data sheet of two companies for each first week of January, April, August and October. An average loading weight, length of transport and lairage times and mortality were 3.9 ton, 96 min, 478 min and 0.6%, respectively. Mortality after lairage was not significant between two types of crate. In addition, container type crate showed higher loading weight and stocking density than box type one. Spring and winter had significantly higher mortality with 0.7 and 0.8%, respectively, then summer and fall of 0.5%. An interaction between crate type and season on mortality showed that mortality for box type on was higher in spring and winter with 0.8 and 0.7%, respectively, compared to summer and fall of 0.3 and 0.4%, respectively. In the case of container type crate, spring, fall and winter had greatly different death rate with 0.7, 0.5 and 0.8%, respectively, while there was no difference between spring and summer, and between summer and winter. Mortality after transportation was similar between both crate type, with higher rate for spring and winder than other seasons. The result was likely related to death of exposure due to extended waiting time without heating facility.
