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

Escherichia coli O157:H7 has been identified as one of the most devastating microorganism causing diseases in human. The infection by this bacteria causes a wide spectrum of clinical manifestations ranging from asymptomatic, diarrhea or bloody diarrhea, up to serious clinical conditions such as hemorrhagic colitis, and hemolytic uremic syndrome. Poultry is known as one of its reservoir besides cattle and pig. Moreover, the use of antibiotic in animal feed as growth promoters is common worldwide. Due to its potential threat to public health, sensitivity test against various antibiotics and studying the plasmid DNA profiles are necessary. The study was initiated by cultivation of isolates, followed by test of antimicrobial susceptibility against various antibiotics and then by analyzing the plasmid DNA profiles. Results of study showed that among of 7 E. coli O157:H7 local isolates originated from chicken feces, as many as 42.9%; 14.3%; 14.3%; and 14.3% were resistant to 2; 3; 4; and 5 various of antibiotics, respectively. Base on the type of antibiotic, 85.7%; 71.4%; and 42.9% showed resistance to Methicillin, Penicillin G, Doxycycline and Streptomycin. Plasmid DNA of each isolates showed characters variation too, ranging from 2 to 4 bands with molecular weight ranging from 19.457 bp; 15.137 bp, 5.749 bp, 4.118 bp, 3.500 bp, 2.957 bp and 2.024 bp. Results of study indicated that local isolates of E. coli O157:H7 isolated from chicken showed multiple antibiotic resistance against various antibiotics, as well as its plasmid DNA profiles.

Abstract

Pigs cannot be separated from the lives of most Indonesians, especially in Bali. Pork will always be a superior commodity among the public. Meat quality is a major factor for consumers to ensure their safety. The method of slaughter plays an important role in determining the quality of the meat, whether it is using the stunning technique and the non-stunning technique. The purpose of this study was to determine the quality of pork slaughtered using electrical stunning and non-stunning techniques by testing the water holding capacity, wetted area and cooking loss parameters. This study used 40 samples of pork hamstrings (musculus biceps femoris), weighing ±50 g/head taken from 40 pigs in two different slaughterhouses in the Darmasaba area. The results showed that the difference in slaughtering techniques did not have a significant effect (P > 0.05) on the value of water holding capacity and cooking loss of pork, while on the value of the wet area, the difference in slaughtering techniques had a significant effect (P < 0.05). It is necessary to conduct a study with a more detailed unit of measurement and a larger number of samples.

Abstract

Streptococcus is a Gram-positive coccus from the family Streptococcaceae that can be found normally in some healthy animal but can cause a disease as well. The purpose of this research is to know the hemolysis profile from pig’s tonsil swab isolated from the traditional pig slaughterhouse at Punggul Village and Bongkasa Village that can be divided into three hemolytic profile; alpha-hemolytic, beta hemolytic, and gamma hemolytic, to know the pathogenicity. This research is divided into several steps, such as; isolating the swab, Gram test, catalase test, oxidase test, and hemolysis test on Sheep Blood Agar. Streptococcus is a Gram-positive coccus, tested Gram positive, catalase negative and oxidase positive. This research concludes the amount of positive Streptococcus sp sample based on hemolysis profile is 6 of 24 samples, whereas 3 of 24 samples (12,5%) has ? hemolysis pattern, 3 of 24 samples (12,5%) has ? hemolysis pattern and none showed the ? pattern. The conclusion from the table; showed positive sample of Streptococcus sp is divided 50:50 for the ? and ? hemolysis, and no sample showed the ? pattern. At most cases, the ? and ? hemolysis Streptococcus is a pathogen bacterium. This data might be useful for references to see the transmission of Streptococcus sp in swine at Abiansemal area in Badung, Bali

Abstract

Pig is one of the crucial livestock in providing animal protein for a portion of the Indonesian population. Pork is one of the critical commodities concerning nutritional, socio-cultural, and economic aspects. This study aimed to determine the water holding capacity (WHC) of meat, i.e., the ability of meat to maintain water content during processing and cooking loss of meat, i.e., a function of temperature and cooking time. Cooking loss is the lost sample weight during smoking related to WHC and meat juice levels. Sampling was performed at the Mr. Mangku traditional slaughterhouse, Abiansemal Sub-District, Badung Regency, Bali. Samples consisted of 16 Balinese pork and 16 Landrace pork from the Psoas major muscle. The laboratory test results were then analyzed using the Two Independent T-test SPSS. The analysis results showed that the WHC of Balinese pork was relatively higher than that of Landrace pork, although insignificant. Meanwhile, the cooking loss of Balinese pork was significantly lower than that of Landrace pork. It can be concluded that the quality of Balinese pork is better than Landrace pork on water holding capacity and cooking loss.

Abstract

The aim of this study was to detect urinary tract problem in dogs using ultrasonography method as a diagnostic supporting tool. Two-dimensional ultrasonography was used for examination of 40 dogs. The diagnosis was confirmed by the alteration of shape, size, position and echogenicity of the renal. Abnormalities on renal were extension of medulla, urolithiasis, and renal atrophy. The extension of medulla was indicated by medulla and pelvis dilatation, also disappearance of renal parenchyma. Sonograms of renal urolithiasis were shown by hyperechoic mass with acoustic shadowing. Narrowing of medulla and disappearance of cortex structure were the characteristics of renal atrophy sonogram. Abnormalities in vesical urinary and urethra were cystitis, urolithiasis, and urethral urolith obstruction, respectively. Ultrasonography utilization as diagnostic supporting tool for the urinary organ abnormalities in dogs generating a high accuracy diagnosis.

Abstract

Calcium is a macromineral that plays an important role in the health, production, and reproduction of animals. Calcium requirements in cattle depend on breed, age and parity, path physiological status, body condition score, gestation status, and lactation. During the periparturient period, the cows struggle to maintain calcium homeostasis, and if it is failed, the animal will experience hypocalcemia. As is known hypocalcemia as a predisposing factor for a number of reproductive disorders and infectious diseases. This study aims to investigate changes in blood calcium levels in Bali cattle during the periparturient period. The object of research is nine months pregnant Bali cattle and in good health, kept in cage in a horticultural farming environment. Three ml blood samples were taken through the jugular vein three times, namely in the last three weeks of gestation, on day parturition, and three weeks after calving. Blood samples were processed using the wet digestion method, and calcium concentrations were measured using the flame atomic absorption spectrometric method. The results showed an average blood calcium concentrations of 9.57±1.26 mg/dl, 4.11±0.63 mg/dl, and 8.32±1.23 mg/dl, respectively. Statistical analysis showed blood calcium levels during delivery experienced a very significant decrease. We find new evidence regarding the physiological data of Bali cattle, that at the time of parturition they experienced subclinical hypocalcemia. We concluded that there was a fluctuating change in blood calcium concentrations, where the normal value in the last three weeks of gestation experienced a significant decrease at the parturition and increased after three weeks of calving but has not yet reached the initial condition.

Abstract

Dermatophytosis (ringworm) caused by dermatophytes fungi is one of the cattle diseases that can infect Bali cattle. Ringworm significantly cause economic loss to farmers and at the same time is zoonotic disease. Diagnosing dermatophytosis based on the clinical signs in the animals, followed by direct microscopic examination of skin scrapings and hair samples and confirmed by laboratory tests. On direct microscopic examination of skin scrapings and hair samples, generally detected the elements of the fungi such as arthrospores or hyphae. In this study, skin scrapings and hair samples from Bali cattle that clinically suffered ringworm were collected. Samples were then placed on an object glass, added drops of 10% KOH, covered with a cover glass, and after 10-15 minutes were examined under a microscope with a magnification of 100X and 400X. We were able to detect macroconidia as well as arthrospores of the fungi. Macroconidia were detected on two of seven samples tested (28.57%). Normally, macroconidia will not be detected prior culturing on agar media and staining with Lactophenol Cotton Blue (LPCB). Dermatophytes fungi produces two types of asexual propagule: the saprophytic conidia and parasitic conidia, depending on the environment where they grow. Macroconidia that were detected in this study are saprophytic conidia possibly from the soil and/or from broken or hair loss. This macroconidia might be a potential source of infection.

Abstract

This study aims to determine the distribution and elimination of lead levels in various tissues of rats (Rattus norvegicus). The study used 32 rats which were divided into 2 groups, namely the control group and the group given 2.00 ppm Pb-acetate. Treatment by administering Pbacetat is carried out orally every day for 30 days (phase 1). On day 31 (phase 1), 8 rats from each group were taken their blood plasma for measurement of lead levels. Measurement of lead levels was carried out using the atomic absorption spectrophotometry (AAS) method. Then the rats were necropsied and the liver, kidneys, spleen, lungs, intestines, heart muscle and brain tissue were taken for histopathological preparation. Histopathological preparations were made according to the hematoxylin eosin (HE) staining. The remaining 8 rats from each group were kept continuously for the next 30 days (phase 2), without giving Pb-acetate solution. This phase aims to determine the level of lead elimination from rat tissues. On day 61, all remaining rats were taken their blood for measurement of lead content. Then the rats were necropsied to take liver, kidney, spleen, lung, intestine, myocardium and brain tissues, the same as in phase 1.The histopathologically examination were categorized based on thehaemorrhage, inflammatory and necrotic lesions. The average of measurement result of lead content in the blood of rats in phase 1 was 0.27±0.06 ppm. Whereas the average of lead content in phase 2 was 0.12±0.03 ppm. This result showed significantly difference by variance of analize. Based on the tissue lesions, the liver, kidneys, spleen and lungs were the main tissues undergoing histopathological changes. Up to phase 2, the liver tissue still has lesions. It can be concluded that lead contamination in 30 days can significantly decrease in the next 30 days. Lead distribution can cause lesions in liver, kidney, spleen and lung tissues. But in phase 2, liver lesions were still found, indicating that liver tissue had the lowest elimination power compared to other tissues
