Abstract: | The objective of the research was to determine the infl uences of heat stress and temperature-exposed time on liver malonaldehyde (MDA), relative weight of bursa fabricius and heterophil/lymfocite ratio of broilers. The research used 140 male broilers of 2 weeks of age. The treatments consisted of two factors. The fi rst factor was fi ve treatments: S1A (28.55±1.53 oC) with ad libitum of feeding, S1BT1 (S1 with pair feeding as S2A), S1BT2 (S1 with pair feeding as S3A), S2A (31.07±1.29 oC) with ad libitum of feeding and S3A (33.50±1.17 oC) with ad libitum of feeding. The second factor was fi ve of temperature-exposed times (0, 4, 8, 16, and 32 days after treatments). Variables measured were liver MDA, relative weight of bursa fabricius and ratio of heterophil/lymphocite (H/L). The experiment used a completely randomized design in split plot (5x5), with 4 replications. The result indicated that liver MDA, relative weight of bursa fabricius and H/L ratio of S2 and S3 were higher than those of S1A, S1BT1 and S1BT2. H/L ratio of 4, 8, 16, and 32 days of temperature-exposed times were higher than that of 0 day. It was concluded that heat stress increased the liver MDA and H/L ratio, but decreased the relative weight of bursa fabricius. The temperature-exposed time increased the H/L ratio, but it did not affect the liver MDA and relative weight of bursa fabricius of broilers. |
