Abstract

Studies on the role of domestic animals in the transmission of schistosomiasis japonica in the West Lore Sub-district, Poso District, are still limited despite its importance as zoonosis. This study used a cross-sectional design to determine schistosomiasis prevalence in domestic mammals and identify the relative contribution of each mammalian species’ schistosomiasis transmission in the West Lore Sub-District. Fecal samples were obtained from 209 animals (seven buffaloes, 70 dogs, 44 cattle, 86 pigs, and two horses). The Danish Bilharziasis Laboratory technique was used to detect both the occurrence of S. japonicum egg in feces and the intensity of schistosomiasis infection. The examination of 1852 human fecal samples using the Kato-Katz method was carried out by the Laboratory of Schistosomiasis Lengkeka. The measurement of environmental pollution with S. japonicum eggs and the relative contribution of each species in the transmission was performed. The highest prevalence of S. japonicum infection in animals was in horses (100%; 2/2), cattle (54.55%; 24/44), and pigs (51.16%; 44/86). The prevalence in buffaloes and dogs was 28.57% (2/7) and 32.86% (23/70). Cattle (69.74%) were the main contributors to S. japonicum eggs contamination in the environment, followed by pigs (21.95%) and buffaloes (4.71%). This study reported a high prevalence of schistosomiasis in animals (45.46%), while low human schistosomiasis prevalence (0.59%).

Abstract

Infeksi Haemonchus contortus atau haemonchosis umumnya terjadi pada ruminansia kecil seperti domba. Haemonchus contortus adalah spesies yang paling patogenik pada ruminansia kecil dan berhabitat di abomasum. Hewan yang terinfeksi Haemonchus contortus  secara berangsur-angsur akan mengalami anemia karena aktivitas cacing yang menghisap darah. Selain menimbulkan anemia, domba akan mengalami penurunan bobot badan akibat penurunan daya cerna. Infeksi tersebut dapat berjalan secara akut maupun kronis dan dalam kondisi tertentu dapat juga mengakibatkan kematian pada hewan. Oleh karena itu dibutuhkan perangkat yang efektif dan efisien untuk mengindentifikasi keberadaan telur cacing Haemonchus contortus sebagai alat deteksi cepat telur cacing. Tujuan dari penelitian ini adalah membuat perangkat cerdas berbasis Algoritma YOLOv3 yang mampu mendeteksi dan mengidentifikasi telur cacing Haemonchus contortus secara cepat.  Penelitian ini menggunakan Algoritma You Only Look Once (YOLO) versi 3 yang merupakan algoritma yang dikembangkan untuk membantu mendeteksi objek secara realtime. Algoritma YOLO dijalankan dalam framework aplikasi anaconda dengan menggunakan pycharm dan aplikasi OPENCV. Identifikasi telur Haemonchus contortus secara otomatis berhasil dilakukan dengan proses tagging pada dataset dan membuat file weight training bagi YOLO. Hasil uji coba menggunakan mikroskop cahaya dan smartphone menunjukan bahwa bahwa Algoritma YOLO mampu mengidentifikasi telur Haemonchus contortus dengan nilai confidence lebih dari 90%. Penggunaan perangkat Dino-Lite yang terhubung pada mikroskop cahaya menunjukan algoritma YOLO tidak dapat berjalan karena adanya enkripsi pada perangkat tersebut. Otomatisasi pendeteksian telur Haemonchus contortus dapat dilakukan dengan memanfaatkan Algoritma YOLOv3 yang dibantu dengan hardware berupa laptop dan smartphone android serta memiliki kemampuan identifikasi dengan tingkat akurasi yang tinggi.

Abstract

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.

Abstract

The anthelmintic activity of Cassia surattensis extract was strongest compared to C. siamea, C. fistula, and C. spectabilis extracts against Haemonchus contortus shown in previous studies. The study aimed to test the effectiveness of C. surattensis leaf extract against adult pinworms in mice (Mus musculus), based on the number eggs per gram feces (EPG) and the number of worm. A total of 30 male Deutschland Denken Yoken (ddY) strain mice aged 1.5-2 months with average body weight (bw) of 24.3 g were used in this study. The treatments applied included P0 = negative control, P1 = administration of C. surattensis extract at a dose of 125 mg/kg bw, P2 = administration of C. surattensis extract at a dose of 250 mg/kg bw, P3 = administration of C. surattensis extract at a dose of 500 mg/kg bw, and P4 = positive control. Administration of C. surattensis extracts for three consecutive days, according to the dose of each treatment. The efficacy of the extract of C. surattensis was evaluated by looking at the decrease in the number of EPG and the number of worms at the time of necropsy. The results showed that the maximum efficacy of the extract of  C. surattensis at a dose of 500 mg/kg bw against pinworms with a decrease in EPG and the number of worms was 54.11 - 82.47% and 41,60%. This proves that C. surattensis extract has significant efficacy as an antinematode, so that it can be used as a conventional anthelmintic

Abstract

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.

Abstract

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

Abstract

The dissemination of research findings (innovation) in universities would have a social and economic impact on the larger community. IPB developed the depolarized katuk invention (known as Katulac), which was patented (P00201800110, Jan 5, 2018). IPB collaborated with the Local Government of Central Lampung Regency, PT Great Giant Livestock (GGL), and community farms named Hipermadani (downstreaming of university innovation for the community and farmers) in downstreaming Fedtugrow (innovation in combined livestock feed Katulac® and concentrate) to improve farmer welfare. Katulac®'s downstream innovation is the School for Smallholder Livestock Farming (Sekolah Peternakan Rakyat, SPR), an IPB innovation with copyright (EC00201987765, Nov 28, 2019). The Katulac® downstreaming initiative with SPR institutional integration resulted in a social investment of IDR 501,837,278 and a net social benefit of IDR1,488,959,391 for all stakeholders in the Hipermadani ecosystem. This program had a Social Return on Investment (SROI) of 2.97, which means that for every IDR 1 invested, it would deliver a social benefit of IDR 2.97, showing the program's success. Keywords: downstreaming, Hipermadani, innovation, Katulac, Social Return on Investment

Abstract

This study included 21 recently calved FH cows divided into three treatment groups: control (P0), depolarized katuk (Sauropus androgynus) leaf powder (P1), and depolarized katuk leaf pellet (P2). The study found that the dry matter intake for treatment P0, P1, and P2 were 15.59 ± 0.91 kg, 15.14 ± 1.38 kg, and 16.27 ± 1.28 kg, respectively. Milk production in these three different treatments were 25.91±5.94 L, 23.80±3.42 L, and 32.11±4.75 L, respectively. The dry matter percentage of milk (total solid) in P0 was 21.75±11.67%, P1 was 21.7±0.99%, and P2 was 31.0±10.75%. Depolarized katuk leaves, particularly in pellet form, resulted in much higher milk production than the control group. These data suggest that feeding depolarized katuk leaves as a supplementary feed to FH dairy cows can improve milk supply and quality during the first month of lactation. The inclusion of depolarized katuk leaves, particularly in pellet form, may be a useful technique for increasing dairy cattle productivity and health. Keywords: friesian holstein, depolarized katuk leaves, milk quality, 1-month lactation, milk production

Abstract

This epidemiological investigation conducted in three regencies of West Sumatra, Indonesia, aimed to examine the molecular prevalence and distribution of Babesia bigemina, Babesia bovis, and Theileria orientalis. A cross-sectional study employing a convenience sampling technique included 151 cattle blood samples. These samples were collected from three regencies (Agam, Limapuluh Kota, and Tanah Datar) between January 2023 and February 2024. Blood samples were examined using polymerase chain reaction (PCR) coupled with sequencing, targeting the cytochrome b gene for B. bigemina and B. bovis, and the 18S rRNA gene for Theileria spp. A total of 151 cattle blood samples from West Sumatra were examined for hemoprotozoan infections using both microscopic and molecular approaches. Based on blood smear examination, 23 (15.2%) and 118 (78.1%) samples were positive for Babesia spp. and Theileria spp., respectively. Subsequent nested PCR analysis confirmed all Babesia-positive samples as B. bigemina, while B. bovis was not detected. In contrast, 131 (86.7%) samples were molecularly identified as T. orientalis. Phylogenetic analysis of the cytochrome b gene revealed three distinct clades of B. bigemina, indicating genetic diversity likely shaped by geographical distribution, vector ecology, or host adaptation. These findings demonstrate that T. orientalis is the predominant hemoprotozoan agent in West Sumatra, while the genetic variability of B. bigemina underscores the complexity of its epidemiology. Together, these results provide critical insights for improving surveillance and guiding the formulation of effective hemoparasite management strategies in the tropical Indonesian archipelago.

Abstract. Nirwan M, Hadi UK, Soviana S, Satrija F, Setiyaningsih S. 2022. Diversity, domination and behavior of mosquitoes in filariasis endemic area of Bogor District, West Java, Indonesia. Biodiversitas 23: 2093-2100. A study on the diversity, dominance and behavior of mosquitoes was done in the two filariasis endemic areas in Bogor District, West Java, Indonesia. The objectives of this study were to determine the diversity, dominance and behavior of mosquitoes and their importance as vectors of filariasis in two endemic areas in Bogor District, namely Tamansari Village (rural) and Cimanggis Village (urban). This research was carried out from September 2019 to February 2020. Mosquitoes were collected from 6.00 pm to 6.00 am, twice a month in each village, by using the bare leg collection technique. The collected mosquitoes were identified and analyzed. Filaria detection was carried out by dissecting technique and polymerase chain reaction (PCR). The result indicated eight (8) species of mosquitoes in the rural area (Tamansari village), i.e., Culex quinquefasciatus, Aedes aegypti, Cx. vishnui, Cx. tritaeniorhynchus, Armigeres kesseli, Ar. subalbatus, Ae. albopictus, Mansonia annulata. On the other hand, there were six (6) species found in the urban area (Cimanggis village), i.e., Cx. quinquefasciatus, Ae. aegypti, Ar. kesseli, Ar. subalbatus, Cx. vishnui, Cx. tritaeniorhynchus and Cx. quinquefasciatus were found to be the most dominant in Tamansari village (90.46) and also in Cimanggis Village (95.67). Based on the analysis showed that the mosquito diversity index was low in both the Tamansari village (H’: 0.444) and the Cimanggis village (H’: 0.238). In general, mosquito-biting behavior prefers to suck blood indoors (anthropophilic) with a peak density in the range of 23.00-04.00. The results of filarial detection using dissecting technique and PCR methods against mosquitoes caught in Tamansari Village and Cimanggis Village did not find any L3 larvae and microfilariae in the examined mosquitoes. Culex quinquefasciatus was found to be very potential as the main vector for the spread of filariasis both in rural and urban areas of endemic filariasis of Bogor District, Indonesia.
