Examination and treatment will be carried out on May 22, 2021 – June 3, 2021. The examination method is carried out by clinical examination and laboratory examination. Clinical examination was carried out by inspection and palpation methods. Laboratory examinations were carried out by examining the FCoV Rapid test, blood examination, abdominocentesis, abdominal fluid examination and polymerase chain reaction. Based on the results of the clinical examination, FCoV rapid test, hematology and Rivalta testing, it can be concluded that the FIP case in cat at the Petvet Animal Clinic belongs to the wet type (effusive) FIP. <strong>Conclusion:</strong> It is necessary to carry out other supporting diagnoses such as ELISA (Enzyme-Linked Immunosorbent Assay) and PCR (Polymerase Chain Reaction) testing. There is no cure for this FIP case, but symptomatic and supportive therapy is very helpful to reduce clinical symptoms and increase body endurance.</p> Muhamad Irfan Hartono Endang Endrakasih Harry Harry Copyright (c) 2022 Muhamad Irfan Hartono 2022-04-29 2022-04-29 3 1 1 5 10.20473/javest.V3.I1.2022.1-5 Comparison of Broiler Performance in Closed House and Open House Systems in Trenggalek <p><strong>Background:</strong> According to the Indonesian Central Bureau of Statistics, broiler meat production in 2020 decreased by 6.3% from the previous year. Several factors can influence chicken productivity, one of which is cage management. The cage has a vital role in success because the comfort of the cage will result in maximum chicken productivity. <strong>Aim:</strong> To compare the productivity of broiler chickens reared using Closed House and Open House cage systems in the same partnership based on the value of Feed Conversion Ratio, Mortality, and Index Performance. <strong>Methods:</strong> Data collection was carried out using the literature and observative methods, namely direct observation on two farms using a Closed House and an Open House cage system in Trenggalek Regency in April 2021. <strong>Results:</strong> A FCR value of Closed House system cages has an FCR value of 1.416, whereas the Open House system was 1.605. The mortality of broiler chickens reared in the Open House system was 842, and in the closed house system was 572. The index performance of broiler chickens raised in the Closed House system was 366.5, whereas in an Open House system, the index performance was 319.4. <strong>Conclusion:</strong> The Feed Conversion Ratio (FCR), Mortality, and Index Performance Index (IP) value of broiler chickens reared in the Closed House system cage was higher than those in the Open House system cage.</p> Ana Rohmatul Laili Ratna Damayanti Boedi Setiawan Sri Hidanah Copyright (c) 2022 Ana Rohmatul Laili 2022-04-29 2022-04-29 3 1 6 11 10.20473/javest.V3.I1.2022.6-11 Evaluation of Production Peak of Laying Hens Strain Lohman Brown in CV. Lawu Farm Malang <p><strong>Background</strong>: The productivity of laying hens is a key measurement in the laying hens business. One of the targets for laying hens is to achieve peak production. The optimal peak production period is necessary to attain the maximum profit. <strong>Purpose</strong>: To determine the productivity of laying hens strain Lohman Brown aged 25-49 weeks at CV. Lawu Farm Malang Regency as an evaluation of the peak production period. <strong>Case Analysis</strong>: The descriptive method with the case study technique was used. Primary data were obtained from observations by participating in direct livestock activities, interviews, and documentation, and secondary data were obtained from literature studies. The variables observed in this study were Hen Day Production, Feed Conversion Ratio, egg weight, and mortality. <strong>Results</strong>: Observation of laying hens productivity in CV. Lawu Farm showed that 71.42% of Hen Day Production value of the full cages had met the target with HDP of more than 92%, while 28.58% did not reach the peak production target by only getting HDP less than 90%. The FCR value was 2.4 – 2.15, the average egg weight wais 63.03 grams/egg, and the mortality was ≤3%. <strong>Conclusion</strong>: The productivity of laying hens of the Lohman Brown strain aged 24-59 weeks at CV. Lawu Farm has met production standards in terms of HDP, FCR, egg weight, and mortality.</p> Yolifia Rahma Milenia Sri Pantja Madyawati Agung Budianto Achmad Ratna Damayanti Copyright (c) 2022 Yolifia Rahma Milenia 2022-04-29 2022-04-29 3 1 12 17 10.20473/javest.V3.I1.2022.12-17 Catheterization as a Treatment for Feline Lower Urinary Tract Disease (FLUTD) Case in K and P Clinic Surabaya <p><strong>Background:</strong> Feline Lower Urinary Tract Disease (FLUTD) is a case that occurs due to bladder and urethra dysfunction in cats. One of the symptoms of FLUTD is pollakiuria without polyuria, the presence of stranguria, and hematuria. <strong>Purpose:</strong> This case study aims to provide information regarding handling cases of Feline Lower Urinary Tract Disease (FLUTD) in 22 cats for one month at the K and P clinics in Surabaya. <strong>Case Analysis:</strong> Observation data presented descriptively were compared and discussed with supporting data. <strong>Conclusion:</strong> Inserting a catheter is the primary action that must be done if there is a blockage in the urethra.</p> Annisha Permata Nurul Azhar Lailia Dwi Kusuma Dewi Palestin Palestin Copyright (c) 2022 Author(s) 2022-04-30 2022-04-30 3 1 18 21 10.20473/javest.V3.I1.2022.18-21 In Vitro Cytotoxicity Test of Red Okra (Abelmoschus esculentus) Fruit Ethanolic Extract on HeLa Cells <p><strong>Background:</strong> Cancer is one of the leading causes of death in pets. Among various therapeutic methods, chemotherapy is still the main choice to treat advanced and metastatic cancers. However, because of its non-target-specific mode of action, chemotherapy often causes severe side effects in patients. <strong>Purposes:</strong> This study aimed to analyze the cytotoxic effect of red okra fruit extract (<em>Abelmoschus esculentus</em>) on HeLa cells with a comparison of several incubation periods of therapy. <strong>Methods:</strong> Red okra fruit was extracted by the maceration method using 96% ethanol. Then its cytotoxic potency was tested in vitro on HeLa cells based on the MTT tetrazolium reduction assay. <strong>Results:</strong> The results of the MTT test showed a decrease in the viability of HeLa cells along with an increase in the concentration of red okra extract (400, 800, dan 1,600 ppm), where the highest percentage of cell inhibition was obtained at a concentration of 1,600 ppm for each group of 24, 48, and 72 hours of therapy. The lowest IC<sub>50</sub> value was obtained by the 48-hour therapy group, which was 631.78 ppm, indicating the optimal duration of therapy of red okra against HeLa cells. <strong>Conclusion:</strong> The ethanolic extract of red okra (<em>Abelmoschus esculentus</em>) has an anticancer effect by inhibiting the growth and proliferation of HeLa cells. Thus, red okra fruit has potential benefits in the management of animals diagnosed with cancer.</p> Agung Budianto Achmad Copyright (c) 2022 Author(s) 2022-04-30 2022-04-30 3 1 22 26 10.20473/javest.V3.I1.2022.22-26
