密閉式水簾雞舍統進統出飼養模式對蛋雞產蛋率與死亡率之影響
Effects of all-in-all-out mode of wet-pad laying hen housing system on egg production and mortality in laying hens
摘要
本研究旨在探討密閉水簾式雞舍統進統出飼養模式對蛋雞產蛋與死亡率之影響。針對臺灣南部一家牧場有二種雞舍，密閉式水簾及非開放式高床蛋雞舍，分別進行統進統出及分批飼養，並蒐集其第一產蛋年19－80週齡的蛋雞數據，分析比較兩種飼養模式統進統出（密閉式水簾）及分批飼養（非開放式高床）蛋雞的週產蛋率及週死亡率的差異顯著性。結果顯示，統進統出（密閉式水簾）的飼養模式於產蛋後期週產蛋率及週死亡率顯著地較傳統分批飼養（非開放式高床）為佳（P＜0.001）。整個試驗全期，在平均週產蛋率中，密閉式水簾雞舍統進統出模式顯著地較分批飼養改善30.56%的產蛋率（P＜0.001），但平均週死亡率方面，兩種模式間則無顯著的差異。綜上所述，密閉式水簾蛋雞舍統進統出的飼養模式對產蛋後期產蛋率及死亡率，有顯著地較傳統分批飼養（非開放式高床）為佳，因此有利蛋雞產業經營。

The aim of this study was to investigate the effects of all-in-all-out mode of wet pad laying hen housing system on egg production and mortality in laying hens. Two housing systems, wet pad housing system with all-in-all-out production mode and non-open housing system with the batch feeding mode, underwent separate feeding in an individual chicken houses in the same farm in southern Taiwan. The data on weekly egg production rates and mortality during the first laying cycle (19 ~ 80 weeks old) were compared. The results showed that the weekly egg production and mortality rate of wet pad housing system (all-in-all-out) were significantly better than non-open housing system (P ＜ 0.001). During the whole trial period, the wet pad housing system had a significantly improved weekly egg production rate up by 30.56%, as compared with non-open housing system (P ＜ 0.001), despite no differences (P ＞ 0.05) in the mean weekly mortality. In summary, the wet pad housing system with all-in-all-out production mode has better egg production rate and lower mortality rate than those of the non-open housing system, particularly in the late stage of laying period, suggesting beneficial outcomes for the egg industry.
