| dc.description.abstract | The objective of this experiment was to study the health performance of pregnant holstein cow after administration of Escherichia coli inactive vaccine. Two holstein cow in dry period were used in this experiment. Vaccinations through intramuscular route were given 3 times at 8, 6, and 4 weeks before parturition. Status health were monitored during 3 days before and after the first, second, and third vaccination, respectively. The result showed that one day after the first vaccination, temperature of cow no. 1 and cow no.2 increased 1.8% and 0.5%, respectively. The heart rate increased 26.3% and 21.7% in cow no. 1 and cow no.2, respectively. While, respiration rate of cow no. 1 increased 44.4% and cow no. 2 increased 23.1%. After second vaccination, temperature of cow no. 1 and cow no.2 decreased 2.1% and 0.3%, respectively. Heart rate was the same wether 0 day vaccination in cow no. 1 and cow no. 2. While, respiration rate of cow no. 1 decreased 20% and cow no. 2 increased 14.3%. After third vaccination, temperature of cow no.1 was the same wether 0 day vaccination, and cow no.2 decreased 2.1%. Heart rate decreased 5.6% and 11.5% in cow no.1 and cow no.2, respectively. Respiration rate of cow no. 1 decreased 11.1% and cow no. 2 decreased 10%. In conclusion, the administration of E.coli vaccine during dry period did not effect the health status. The administration of E.coli vaccine increased the body temperature, heart and respiration rate a day after vaccination, however were still in the normal range. On the other hand, body temperature, heart rate, and respiration rate in second and third vaccination remain stabile. | id |
