Production cost data were collected from 1996.1 to 1996.12, including1,367 batches of open housing system. Overall, the data analysis indicated that the stocking densities were higher in the enclosed type(15.89 birds/m2)than the open type (11.12 birds/m2) housing system(15.74 birds/m2 ). Livability averaged 90.40 % in open housing and 93.26 % in enclosed housing. Average final body weight was 1.89 kg and 1.94 kg in the open and enclosed housing, respectively. Feed efficiency rate was 1.94 and 1.87, and production index was 215.1 and 231.2 in the open and enclosed housing, respectively.

The direct cost in the enclosed house(31.571 NT/kg) was consistently lower than that in the open house(34.477 NT/kg). It will not justify constructing an enclosed housing in stead of an open housing when cost difference was over 4127.5 NT/m2. Chen Bao-Ji 陳保基 1997 學位論文 ; thesis 119 zh-TW |

碩士 === 國立臺灣大學 === 畜產學系 === 85 === The present study was designed to compare the production
performance and costs of broiler production between open and
enclosed housing system in Taiwan.Furthermore, it was to
estimate the difference in economic efficiency betweentwo types
of housing system in order to find better housing system for
broilerproduction. Production cost data were collected from
1996.1 to 1996.12, including1,367 batches of open housing
system. Overall, the data analysis indicated that the stocking
densities were higher in the enclosed type(15.89 birds/m2)than
the open type (11.12 birds/m2) housing system(15.74 birds/m2
). Livability averaged 90.40 % in open housing and 93.26 % in
enclosed housing. Average final body weight was 1.89 kg and
1.94 kg in the open and enclosed housing, respectively. Feed
efficiency rate was 1.94 and 1.87, and production index was
215.1 and 231.2 in the open and enclosed housing, respectively.
Production performance was more efficient during the fall and
spring season thanthe winter and summer season for both of the
two types of housing system. The direct cost in the enclosed
house(31.571 NT/kg) was consistently lower than that in the
open house(34.477 NT/kg). It will not justify constructing an
enclosed housing in stead of an open housing when cost
difference was over 4127.5 NT/m2.
