Primary data was taken by interviewing inseminators and farmers, while secondary data was taken from the Fisheries and Animal Husbandry Department of Tuban regency. The total sample was 360 cows consisting of 30 PO, Limpo, and Simpo cows aged 3, 4, 5, and 6 years respectively which were calculated based on the Roscoe formula. Data was analyzed using the Simple Linear Regression and ANOVA followed by Duncan's multiple range test at a significance level of 95%. The results showed that the services per conception (S/C), conception rate (CR), and calving rate (CvR) were not significantly different (p &gt;0.05) between PO, Limpo and Simpo cows. Meanwhile, days open (DO) and fertility status (FS) of PO cows were higher (p &lt;0.05) than Limpo and Simpo cows. There was no significant difference (p &gt;0.05) in DO and FS between Limpo and Simpo cows. The linear equation with age as a predictor (X) of S/C, DO, and CI (Y) values were not significant (p &gt;0.05) in PO, Limpo, and Simpo cows. It could be concluded that the reproductive performance of PO cows was better than Limpo and Simpo cows.</p> 2023-11-21T00:00:00+07:00 Copyright (c) 2023 Septiana Alafia Yusi Ardiyansyah, Sri Agus Sudjarwo, Nusdianto Triakoso, Tri Wahyu Suprayogi , Ismudiono Ismudiono, Oky Setyo Widodo Effect of white guava (Psidium guajava L.) fruit juice on the quality of lead acetate induced rats (Rattus norvegicus) spermatozoa 2023-10-22T10:37:04+07:00 Annisa Alifia Sri Mulyati Wurlina Wurlina Tatik Hernawati Budi Utomo Soeharsono Soeharsono Sri Agus Sudjarwo Muhammad Thohawi Elziyad Purnama <p>This study aims to determine the effect of the administration of white guava (<em>Psidium guajava</em> L.) fruit juice on spermatozoa plasma membrane integrity (PMI), morphological abnormality, viability, and motility of lead acetate induced rats (<em>Rattus norvegicus</em>). Twenty-five male rats were divided into five groups: NC (negative control) group, rats were administered with distilled water twice daily at four-hour intervals; T0 (positive control) group, rats were administered daily with lead acetate 50 mg/kg bw and distilled water four hours later; T1, T2, and T3 groups, rats were administered daily with lead acetate 50 mg/kg bw and 0.5 mL of 25, 50, and 100% white guava fruit juice four hours later. The treatment of the rats was conducted for 14 days, and on day 15, all rats were sacrificed to assess the spermatozoa quality. Data was analyzed using ANOVA followed by Duncan's multiple range test at a confidence level of 95%. The results showed that exposure to lead acetate (T0) caused lower spermatozoa PMI, viability, and motility as well as higher spermatozoa morphological abnormalities (p &lt;0.05) compared to those of the T0 group. Administration of white guava fruit juice starting at a dose of 25% (T1) resulted in higher spermatozoa motility, viability, and PMI as well as lower spermatozoa morphological abnormalities (p &lt;0.05) compared to rats in the T0 group. It could be concluded that white guava fruit juice maintained the spermatozoa quality of lead acetate induced rats.</p> 2023-11-23T00:00:00+07:00 Copyright (c) 2023 Annisa Suci Alifia, Sri Mulyati , Wurlina Wurlina , Tatik Hernawati , Budi Utomo , Soeharsono Soeharsono , Sri Agus Sudjarwo, Muhammad Thohawi Elziyad Purnama Effect of Peganum harmala seeds extract on the hepatic tissue structure and fetus of mice 2023-11-12T09:28:30+07:00 Samira Musa Sasi Nagia Al ghoul Nuri Awayn Ahmed El ghoul Ragil Prastiya <p><em>Peganum harmala</em> is one of the most used plants for the treatment of many diseases. Its effective compounds have pharmaceutical and medicinal properties. This study aims to determine the effect of aqueous extract of harmala plant seeds on body and liver weight, aspartate aminotransferase (AST), alanine transaminase (ALT), and the histological structure of liver of mice, as well as the size of the fetuses sired by treated mice. Sixteen adult male mice were divided into two groups of eight. The first group (control) was given distilled water orally, while the second group received the aqueous extract of harmala seeds at a dose of 300 mg/kg bw for three weeks. three untreated females were housed with one treated male for mating. At the end of the treatment, six male mice of each group were weighed and killed. Liver was extracted, weighed and its enzymes were measured. Also, sections of the liver were prepared for histological examination. The results showed a decrease in the body weight of the treated mice and a significant increase in the average weight of the fetuses compared with the control group, as well as marked changes in the hepatic tissue structure. There was no impact of the extract on fetal body length, liver weight and hepatic enzymes (AST and ALT) of treated mice. Further studies should be conducted to determine a safe dose that does not affect any organ in the body, so that it can be used for the treatment of many diseases.</p> <p> </p> 2023-11-27T00:00:00+07:00 Copyright (c) 2023 Samira Musa Sasi, Nagia Musa Alghoul, Nuri Awayn, Ahmed Elghoul, Ragil Angga Prastiya Impact of green tea (Camellia sinensis) leaf extract in skim milk-goose egg yolk semen extender on the quality of Sapudi ram spermatozoa stored at 5°C 2023-10-29T08:48:40+07:00 Ardina Sahra Miranda Tri Wahyu Suprayogi Budi Utomo Suherni Susilowati Yeni Dhamayanti <p>Livestock production requires Sapudi rams, a breed native to Indonesia, to meet meat demand and food security. In artificial high-quality frozen semen is needed to spread Sapudi rams. To maximize the survival of spermatozoa during cryopreservation, semen should be stored in an extender. Green tea leaf extract (GTLE) and skim milk-goat egg yolk (SM-GEY) may be a good cryoprotectants due to their antioxidant properties. This study aimed to determine the effect of adding GTLE to the SM-GEY extender on the quality of Sapudi ram spermatozoa stored at 5°C. The fresh semen sample was divided into four different GTLE treatment groups, which each contained a 0.1 mL semen sample and a 25-mL extender of SM-GEY. Group T0: no GTLE added to SM-GEY; Groups T1, T2, and T3: 0.1 mL semen diluted in 25 mL SM-GEY with 0.05, 0.10, and 0.15 mg GTLE. Extended semen was then stored at 5°C, and its quality was evaluated daily for five days. The variables observed included spermatozoa motility, viability, and membrane integrity. Data were analyzed using one-way analysis of variance followed by Duncan's test using Statistical Program and Service Solution version 23. The result of this study was that adding 0.05 mg GTLE to 25 mL of SM-GEY extender significantly maintained the spermatozoa motility, viability, and plasma membrane integrity of Sapudi ram spermatozoa for three days at 5°C (p &lt;0.05). Therefore, it could be concluded that adding 0.05 mg of GTLE to the SM-GEY extender preserved Sapudi ram spermatozoa's motility, viability, and membrane integrity for three days at 5°C.</p> 2023-12-07T00:00:00+07:00 Copyright (c) 2023 Ardina Sahra Miranda, Tri Wahyu Suprayogi, Budi Utomo, Suherni Susilowati, Yeni Dhamayanti Reproduction record of captive Sumatera elephant (Elephas maximus sumatranus) at Way Kambas National Park, Indonesia 2023-11-08T19:43:41+07:00 Keren Jayanti Sofie Adi Budiarto Budiarto Hermin Ratnani Pudji Srianto Budi Utomo Suzanita Utama Setiawan Koesdarto Nurhusien Yimer <p>This research aims to determine reproductive data on Sumatran elephants (<em>Elephas maximus sumatranus</em>) in the ETC and ERU of Way Kambas National Park, Indonesia during 1988-2021. Data recorded from the elephant population at both locations (ETC and ERU) includes the number, gender of elephants, elephant calves, ages and birth dates. Calving intervals and service periods were calculated from calving records of cows with a minimum parity of two. Data collection produced data on 47 elephant calves from 13 female elephants with at least twice the parity and 12 primiparous cows. Elephant reproductive records at ETC and ERU were: age (37.44 ± 9.03 vs. 29.75 ± 3.30 years), parity (2.78 ± 1.09 vs. 2.50 ± 0.58), and age at first birth (18, 11 ± 3.92 vs. 17.75 ± 0.50 years). While the calving interval was 1857.56 ± 870.81 vs. 1833.00 ± 305.18 days, and service period respectively 1229.44 ± 846.18 vs. 1210.50 ± 283.59 days, respectively. It can be concluded that the calving interval and service period for captive elephants at ETC and ERU were not much different and were within the normal range. Young cows showed better reproductive efficiency than older cows. Monitoring calves is very important. Further assistance is needed to improve elephant mobile veterinary services, increase diagnostic laboratory capacity, and educate camp managers, veterinary assistants, and mahouts about elephant diseases, their monitoring and treatment. In addition, the use of reproductive technology such as monitoring ovulation using ultrasound and carrying out artificial insemination was expected to increase reproductive efficiency.</p> 2022-12-08T00:00:00+07:00 Copyright (c) 2023 Keren Jayanti Sofie Adi, Budiarto Budiarto, Hermin Ratnani, Pudji Srianto, Budi Utomo, Suzanita Utama, Setiawan Koesdarto, Nurhusien Yimer
