PENGARUH FISIOLOGIS SAPI PERAH PADA KONDISI LINGKUNGAN TERKONTROL

Abstract

This research aims to determine the physiological responses of FH crossbred dairy cows kept in a
controlled microclimate barn in a tropical lowland area. Eight (8) FH crossbred cows were subjected
to two (2) treatments with 42 repetitions each, which were housed in a controlled microclimate barn.
The FH crossbred cows were housed without any cooling equipment, such as sprinklers and fans (a),
and then with cooling equipment, including sprinklers and fans (b), each for one (1) week. The
observed parameters were barn temperature, body temperature, and respiratory rate in the morning
(06.00), afternoon (13.00), and evening (17.00). The data were analyzed using a statistical sample Ttest with the help of SPSS. The results of the data analysis showed that the barn temperature in
treatments (a) and (b) in the morning was 26±0.81 and 25.25±0.95oC, respectively, and there was no
significant difference statistically (P>0.05). However, the barn temperature in the afternoon for
treatments (a) and (b) was (33.5±0.57 and 30.25±1.70oC), respectively, and there was a significant
difference statistically (P<0.05). Similarly, the barn temperature in the evening for treatments (a) and
(b) was (32±0.81 and 29.25±1.5 oC), respectively, and there was a significant difference statistically
(P<0.05). Regarding the physiological responses of FH crossbred cows, the body temperature in the
morning for treatments (a) and (b) was (37.66±0.45 and 37.21±0.47oC), respectively. The body
temperature in the afternoon was (38.15±0.50 and 37.39±0.73oC), respectively, and in the evening
was (38.07±0.48 and 37.43±0.45oC), respectively. There was a significant difference statistically  (P<0.05) in all three time periods. As for the respiratory rate, in the morning, there was no significant
difference statistically (P>0.05) between treatments (a) and (b), with rates of (33.71±5.82 and
33.28±7.78 breaths/minute), respectively. However, in the afternoon, the respiratory rate for
treatments (a) and (b) was (57.96±13.31 and 43.75±14.07 breaths/minute), respectively, and in the
evening, it was (50.89±9.30 and 42.82±8.39), respectively. There was a significant difference
statistically (P<0.05) for both afternoon and evening periods. Based on the research results, it can be
concluded that the controlled microclimate barn conditions have an impact on the physiological
responses of FH crossbred cows in the tropical lowland area.
