Abstract
Bali cattle have very good potential for meat and calf supply, because they have good adaptability with good quality reproductive properties. However, good reproductive nature is threatened by diseases caused by bacteria. This study aims to determine the number and types of bacteria in the vagina of Bali cattle that are estrus and pregnant. Sample using vaginal swabs from 30 cows. The sample consisted of 10 swabs from non-estrus and not pregnant (control / normal) cattle, 10 swabs from estrus cows, and 10 swabs from pregnant cows. After the swab is carried out using a cotton bud, the results of the swab are stored in Stuart transport media. Samples planted in blood media to be identified and the number of colonies counted, then followed by Gram staining and biochemical tests then the results were presented descriptively. The result is the highest number of estrous cow colonies (1034 colonies), compared to non-estrous and non-pregnant cows (407 colonies) and pregnant (376 colonies). This type of bacteria is dominated by Klebsiella sp. (42.85%), Eschericia coli (28.7%), Streptococcus sp. (14.28%) and Bacillus sp. (14.28%).
Highlights
It needs to be investigated in this case the number of bacteria and what types of bacteria are in the reproductive tract of female cows, so that prevention and treatment can be done early so that bacterial infections during estrus and pregnancy can be addressed
The number of colonies that grows most is atestrus cows, this is inversely proportional to the revelation [6], where the results of the study show that during estrus where the hormone estrogen dominates during the follicular phase, there is an increase in leukocyte migration to the uterine lumen thereby increasing bactericidal activity
2019, samples were taken at Sobangan the follicular phase only 22.47% compared to the luteal phase 52
Summary
This is because Bali cattle have very good javanicus, Bos / Bibosbanteng) are one type of cattle that is important for the potential for the supply of meat and calf because they have good adaptability with. Reproductive tract of female cows, at the time of estrus where the cow is ready to be mated and when pregnant which is capable of causing abortion It needs to be investigated in this case the number of bacteria and what types of bacteria are in the reproductive tract of female cows, so that prevention and treatment can be done early so that bacterial infections during estrus and pregnancy can be addressed
