Abstract

Bovine Viral Diarrhea (BVD) or malignant diarrhea in cattle is one of the animal diseases that causes economic losses in the cattle industry worldwide. The biggest economic loss due to infection by Bovine Viral Diarrhea is related to reproductive and calf disorders that continue to transmit the virus to other cattle. This study aims to determine the presence of Bovine Viral Diarrhea antibodies in Bali cattle. The sample uses Bali cattle’s blood from 30 cows that are accommodated in 2 tubes that contain anti-coagulant and which do not contain anti-coagulant. After being processed to get serum, plasma and buffy coat cells, then the samples were examined using the ELISA method and presented descriptively. The results showed that there were positive suspects in Sobangan village, Badung with 8 out of 15 samples (53%) and positive suspects in the village of Payangan, Gianyar with 3 out of 15 samples (20%). Positive results are influenced by biosecurity of each type of sample farm, in Sobangan village is a large farm so biosecurity is difficult to implement and the spread of disease is faster than in Payangan village that have small farm type.

Abstract

The animal products quality is influenced the physiological compounds in the blood, for example lactic acid. If blood lactic acid levels increase before slaughtering will be accelerate the rigor mortis of meat, thus faster handling is needed. Blood lactic acid also affects the appearance of flesh color of meat. The condition of animals before slaughter (rest period in quarantine) is very influential on rigor mortis. It is important to research blood lactic acid levels before animals are slaughtered. This research was conducted to determine the blood lactic acid levels of bali cattle during the rest period before the animal was slaughtered (ante mortem), so it can be predicted the quality of meat products. Purposive was chosen as a sampling method using elisa test as a determination of lactic acid levels. Fourtysamples of blood taken from cows to be slaughtered at Sanggaran Animal Abattoir, Denpasar, Bali. The results showed that the blood levels of lactic acid in cattle would be cut normally. This shows the quality of resting cattle before slaughter is good.

Abstract

This study aims to determine the comparison between Norotate Rotation and Promax Rotation (90) of Biplot Simulation in the management of Bali Cattle Breeding Farms on Integrated Farming System (Simantri). It used to determine the difference of coordinates between the variables and also obtain the information about the difference in the proximity of the coordinates between livestock groups.The study conducted on Simantri who had livestock groups in Badung Regency, Bali in which the data collected were analyzed by factor analysis with Norotate Rotation and Promax Rotation (90). The variable of this study was a livestock management which included management of cows, calves, feed, cowshed, environmental,and the objects of the study were thelivestock groups. The Biplot simulation used to determine the coordinates of the livestock groups determined based on the Factor Scores Method Regression Analysis. The results with different rotations caused differences in the magnitude of the arrow angles and directions between management of cows, calves, feeds, cowshed and environmental which also followed by differences in the coordinate systems of the livestock groups. The angle between management of cows, calves, feeds, cowshed, and environmental do not show the magnitude of the correlation between them. It can be stated that the coordinates of Livestock groups on Promax Rotation (90) are more specific than Norotate Rotation, therefore it is easier to distinguish the different scores between the variables on the Livestock groups.

Abstract

The successful application of reproductive technology requires knowledge of estrus cycle and the ability to detect estrus of Bali cattle. Estrus in cattle lasts for 8-30 hours showed by the acceptance of males for copulation. In this phase, estrogen levels reach maximum levels. High levels of estrogen cause signs of estrus, and changes in the reproductive organs. This study aims to determine estrogen levels during estrus and external genital changes during estrus. This research was an observational analytic study with cross-sectional study design. The samples used in this study were Bali cattle during estrus. The samples had healthy status without any signs of disease. Blood samples were taken through the jugular vein were then centrifuged to obtain serum. The obtained serum was examined for estrogen hormone levels. Mechanical measurements of hormone levels checked by using the Direct Elisa, Double Antibody Sandwich. Blood samples were collected from several SIMANTRI in Mengwi District, Badung Regency. The results showed in Bali cattle external genitals change when estrus, namely redness of the vaginal mucosa, discharge from the vagina and swelling of the vulva. While estrogen levels when estrus is 69.80 pg/ ml. Further research needs to be continued to measure the quality of ovulation after estrus.

Abstract

General anesthesia in Bali cattle using ketamine and propofol has not been reported. Therefore, research is needed to determine the dosage, time of anesthesia and physiological response of ketamine, propofol, and combinations of both (ketafol). Twelve male calves, weighing 25-45 kg with age of 2-4 months were used in this research. Physiological changes in the cardiovascular and respiratory system, also body temperature was monitored using a physiograph tool. All calves were premedicated with xylazine (0.1 mg/kg BW) intramuscularly, and induced with ketamine (2 mg/kg BW), propofol (2 mg/kg BW) and ketafol (1 mg/kg BW ketamine and 1 mg/kg BW propofol) intravenously after 10 minutes. Ketamine induced calves showed results of induction time after 4.75 ± 1.73 minutes, duration of anesthesia is 13.03 ± 1.15 minutes, and recovery time is 12.01 ± 5.05 minutes. The induction time using propofol is 2.50 ± 0.58 minutes, duration of anesthesia is 15.50 ± 1.91 minutes and recovery time is 2.75 ± 0.96 minutes. Calves induced with ketafol produced5.00 ± 1.41 minutes for induction time, duration of anesthesia was 14.00 ± 1.83 minutes, and recovery time was 4.50 ± 0.58 minutes. The calves that were induced with ketamine, propofol, and ketafol show that the induction time and duration of anesthesia are not significantly different, but for propofol’s recovery time was significantly lower compared with ketamine, but not significantly different from ketafol. Anesthesia using propofol or ketafol can be used in Bali cattle because the physiological changes in the cardiovascular and respiratory system are more stable and no extreme changes was found.

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%).
