Stress responses and live weight loss of Anpera goat as affected by supplement of bioport during transportation

Abstract

The objective of this study was to evaluate the live weight shrunk and stress response in Anpera goat as affected by feeding bioport during transportation. Anpera goat is a dairy type, a cross between Anglo Nubian and Ettawa grade. Twenty-five goats with an average body weight of 20,29±6,15kg (8-22 months) were divided into two groups, consisted of control (n=13) and bioport supplementation (n=12, level 50 g/d). The supplementation was given during and after transportation. All goats were blood sampled, observed physiological responses (respiration rate, heart rate, rectal temperature) and weighed just before loading onto a truck and after loading to assess shrinkage (72 hours transportation). A blood sample was taken to investigate the level of glucose, creatinine, blood urea nitrogen, and hematology. The result showed that bioport supplementation did not have a significant effect on physiological responses and weight loss, but tended to reduce 1% loss of body weight during transportation. The heart rate of the goat is decreased (122,37±8,98 vs 76,32±10,58) after loading while the respiratory rate (41,57±9,15 vs 50,72±3,95) was increased. The average rectal temperature did not show any difference during transportation (39,23±0,34 vs 39,29±0,20). The results indicate that the stress responses of goats due to 72 hours of transportation may increase stress responses and bring about metabolic changes. It was concluded that supplementation bioport was not sufficient to prevent the impact of the stress response of the Anpera goat.
