The experiment was carried out to observe the effect of adding lemuru fish oil in immunized laying hens diet on the health status of chicken through leucocyte profile, stress index, erythrocyte profile, and malonildehyde concentration in liver and spleen. The research design was completely randomized and the obtained data was analized with analysis of variance and continued with Tukey’s Post Hoc test for differences. The experiment used thirty 18 weeks hens ISA brown strain and were divided into five groups. The groups were: A (immunization with lipase and control diet); B (immunization with lipase, control diet + 1% lemuru fish oil); C (immunization with lipase, control diet + 2% lemuru fish oil); D (immunization with lipase, control diet + 3% lemuru fish oil); and E (unimmunized and control diet). The immunization was repeated three times with four weeks interval, blood was collected and analyzed two weeks after immunization and the malonyldehyde concentration in liver and spleen was measured two weeks after third immunization. The results showed that there was no significant difference (P>0.05) on all variables. The conclusion of this research that lemuru fish oil supplementation did not affect the health status of immunized hens

This study aims to determine the effect of additional feed with depolarizing katuk leaves on the production and quality of colostrum and colostrum milk in Friesian Holstein dairy cows. There were 21 dairy cows that had just giving birth, divided into 3 groups of 7 each, namely the control group (complete feed), BKD (complete feed added with Depolarizing Katuk Powder), PKD (complete feed added with Depolarizing Katuk Pellet). Depolarizing katuk feed was given 100 grams per head per day as a feed additive. Parameters observed were feed consumption, production and quality of colostrum and colostrum milk. The results showed that there was no difference in the consumption of feed supplemented with depolarizing katuk leaves, colostrum production, milk density, total solid colostrum, Solid non-fat, lactose contents, and protein contents of colostrum and colostrum milk compared to the control group. Significant differences occurred in colostrum milk production, total solid colostrum milk, and fat content of colostrum and colostrum milk. It was concluded that depolarizing katuk leaves could be used as additional feed to increase the production and total solids of colostrum milk, and increase the fat content of colostrum and colostrum milk. Keywords: colostrum, colostrum milk, depolarizing katuk leaf, Friesian Holstein

Rabies is an infectious disease, zoonotic, caused by virus from the genus Lyssa virus and generally transmitted by the bite of rabid animal, especially rabies infected dog. Rabies is preventable but is always fatal to humans if the central nervous system (CNS) is infected. Vaccination has been used as one of rabies prevention programmed. A total of 83 samples were tested using an Indirect ELISA (Enzyme Linked Immunosorbent Assay) to identify post-vaccination rabies antibody titer. Antibody titres correlated with absorbance values and standard solutions concentrations. Absorbance value can be determined using ELISA reader and mobile phone camera. Absorbance were read at 450 nm and 620 nm as reference using ELISA reader and image from mobile phone camera using image processing software (ImageJ). The aim of this study is to compared between ELISA reader as gold standard and mobile phone camera through validity testing such sensitivity, specificity, and accuracy. There is no significant difference between gold standard and alternative test equipment. The mobile phone camera has sensitivity 98,6%, specificity 88.8 % and accuracy 97,5%. The image processing method using ELISA reader is relatively expensive and difficult to hold in laboratory with minimum funds. Image processing method using a mobile phone camera with ImageJ application is expected to be an alternative tool to read the result of ELISA.

Provinsi Jawa Barat merupakan satu dari 24 provinsi di Indonesia yang dilaporkan belum bebas Rabies. Usaha pembebasan wilayah Jawa Barat dari penyakit Rabies sangat strategis mengingat posisi Jawa Barat berada di antara daerah bebas Rabies. Jampang Tengah menjadi salah satu kecamatan di Sukabumi yang pada tahun 2016 dilaporkan telah terjadi 13 kasus gigitan Rabies. Penelitian ini menggunakan 81 sampel darah anjing lokal yang dikoleksi dari enam desa di kecamatan Jampang Tengah dan diperiksa dengan menggunakan alat Rayto® hematology analyzer. Parameter profil hematologi dikelompokkan berdasarkan perbedaan umur dan jenis kelamin anjing. Hasil pemeriksaan hematologi secara umum berdasarkan umur menunjukkan nilai rataan yang lebih besar pada anjing lokal umur ≥1 tahun dan konsentrasi leukosit menunjukkan nilai statistik yang signifikan berbeda (p<0.05). Berdasarkan jenis kelamin, nilai rataan parameter hematologi secara umum lebih tinggi pada anjing lokal betina dan adanya perbedaan signifikan (p<0.05) pada konsentrasi leukosit dan granulosit.

Bats are the natural host of several highly pathogenic viruses for human, such as SARS-CoV, Marburg, rabies, Hendra, Nipah, and ebola viruses. Bats did not show any clinical symptoms after infection with those highly pathogenic viruses. In addition, excessive inflammation and viremia were not developed in bats after viral infection. The absence of excessive inflammation is the compensation of their evolution as the only flying mammals. Their flight evolution also drives several unique features in their immune response that enable them to control the viral infection. This article summarizes current understandings about the uniqueness of bats as viral reservoir, the viral diversity in bats, the viral spillover from bats to human, and how to prevent the pandemic caused by emerging bat-borne viral zoonoses in the future. The understanding of how the antiviral response in bats work may provide valuable insights to control viral infection in human and domestic animals.

Katuk (Sauropus androgynus), a traditional herb that has been traditionally consumed by breastfeeding mothers to increase their milk production but still has some side effects, such as bronchiolitis obliterans and inhibition of calcium absorbtion. Removing the polar compounds in katuk leaf (depolarized katuk leaf) can eliminate those side effects without eliminating its side effect in increasing milk production and body growth in several production animals. This study was aimed to analyze the physiological status of beef cows consuming diet supplemented with depolarized katuk leaf as feed additive by measuring their hematology and blood mineral profile. Nine Brahman cross cows in the finisher stage, were grouped based on their diet: complete feed (control), complete feed plus depolarized katuk leaf powder (P1; 100 g per day), and complete feed plus depolarized katuk leaf pellet (P2; 100 g per day). Blood sample was collected after six weeks of consumption for analysis of hematological profiles including total erythrocytes, hematocrit, hemoglobin, total leukocytes, stress index (neutrophil-lymphocyte ratio); and blood mineral concentration (calcium and phosphorous). Dietary administration of depolarized katuk leaf did not have any statistically significant effect on all hematology parameters and blood mineral profiles. In conclusion, depolarized katuk leaf can be used as a growth promoter in beef cows without any negative effect on their physiological status.

Standardization of the quality of the depolarized katuk pellet production process as a feed additive is very important to maintain product quality. The production process requires dry katuk leaves (DKK) as raw materials which are then processed into depolarized katuk leaves (DKD), and continues in the pelleting process to become depolarized katuk pellets (PKD). Quality standard can be done by measuring the parameters of nutritional value and also the yield of methanol extract. Nutritional values were obtained from the results of proximate analysis, namely the percentage of dry matter, ash content, crude protein, crude fiber, crude fat, beta-N, calcium, phosphorus, and gross energy (Cal/g). Mean while, the yield of methanol extract was obtained by maceration using methanol solvent. This study aims to evaluate the nutritional value and yield of crude methanol extract of katuk leaves (DKK, DKD, PKD) which can be used as a quality assurance standard for the depolarized katuk pellet production process. In general, the nutritional value of DKD and PKD had the same value as that of DKK, except for calcium which was quite high (P<0.05) in DKD and PKD, and the percentage of crude fiber was lower (P<0.05) in PKD compared to DKK and DKD. The percentage of crude fat in pellets (PKD) was higher (P<0.05) when compared to DKK and DKD. The yield of methanol extract was very high (P<0.05) in DKK, compared to DKD and PKD. The nutritional parameters and the yield of the katuk leaf extract can be used as quality assurance standards for the depolarized katuk pellet production process. Keywords: depolarization, katuk, methanol, nutrition, pellet

Fedtugrow® is a complete feed containing depolarized katuk (Sauropus androgynous) leaves and is beneficial for enhancing the productivity of both dairy and beef cattle. Depolarization technology in katuk leaves involves the removal of polar compounds from the leaf to eliminate the potential side effects resulting from katuk consumption, such as bronchiolitis obliterans and inhibition of calcium absorption. This technology could eliminate side effects without compromising the efficacy of katuk leaves in increasing milk production and body weight gain. This study aimed to evaluate the efficacy of Fedtugrow® in promoting the growth of beef cattle and its impact on the health status of the cattle raised on smallholder local farms with distinct characteristics compared to commercial farms. Ten Limousin male cattle entering the fattening phase were divided into a control group that consumed standard concentrate and a treatment group that consumed Fedtugrow® for three months. Blood was collected at the end of treatment for hematological analysis, including erythrocyte and leukocyte profiles. Cows consuming Fedtugrow® showed a significantly higher average daily gain and lower stress index than the control. Furthermore, no significant differences were observed in the hematological profile, such as total erythrocyte count, hemoglobin level, hematocrit, and total leukocytes. This study showed the ability of Fedtugrow® as a growth promoter without negatively affecting the physiological status of beef cattle raised on smallholder farms. Keywords: Beef cattle, Fedtugrow®, hematology, smallholder local farm
