This study aimed to analyze the economic value of cull female Bali cattle at different ages in Kupang Regency. A total of 40 cows were grouped into young (2-4 years), medium (4–7 years), and old (7–10 years). Economic parameters measured included live animal value, carcass value, non-carcass value, and added value using the Hayami method. Data were analyzed using ANOVA followed by Duncan’s test. The results showed that age significantly affected the proportion of non-carcass components (P<0.05), but not slaughter weight and carcass
percentage. However, the economic value of live animals, carcass, non-carcass, and slaughtering added value increased with age. Older cows generated higher economic returns, although carcass efficiency was relatively constant across age groups. It can be concluded that culling age influences economic value, and the carcass-based selling system (carcass weight) provides more accurate and profitable returns than live weight transactions.

This study aims to determine the effect of Ivermectin on the differential picture of white blood cells of pea goats before and after endoparasite treatment in a semi-intensive rearing system. The study used 11 pea goats placed in individual pens with a platform and fed with KGP 709 concentrate. Ivermectin was given at a dose of 2.5 ml/head. Tools used included a microscope, EDTA tube, syringe, centrifuge, glass slide and cover, and dropper pipette. Parameters observed were white blood cell profile and gastrointestinal parasite infection based on faecal examination. Data were analysed using One Way ANOVA and presented descriptively. Faecal examination results showed gastrointestinal parasite infection with dominant species Haemonchus contortus (5, TPG 1-33), Trichuris spp. (3, maximum TPG 11), Strongyloides spp. (4, maximum TPG 61), Eimeria spp. (6, mild to severe infection), and Cystotoma spp. (5). Ivermectin administration significantly affected the percentage of neutrophils, eosinophils and basophils (p0.05), indicating that Ivermectin did not affect all white blood cell types equally. In conclusion, this study showed that pea goats were infected with gastrointestinal parasites with a predominance of Haemonchus contortus, Trichuris spp., Strongyloides spp., Eimeria spp. and Cystotoma spp. Ivermectin administration was shown to affect neutrophils, eosinophils and basophils, reflecting the immune
response to parasitic infection.

Trypanosoma evansi (T. evansi) merupakan penyebab utama trypanosomiasis pada hewan ternak. Penelitian ini dilakukan untuk menggambarkan variasi virulensi, morfometri, dan karakter genetik empat isolat T. evansi yang berasal dari sapi dan kerbau di Kabupaten Bogor, Jawa Barat. Seluruh isolat diperbanyak pada mencit untuk mengamati periode prepatent, perkembangan parasitemia, ciri morfologi, serta hubungan genetiknya. Hasil penelitian menunjukkan adanya tiga pola virulensi. Isolat dengan virulensi sedang berasal dari sapi dan kerbau menyebabkan kematian mencit pada hari ke-14 pascainfeksi. Dua isolat lain dari sapi menunjukkan virulensi rendah (kematian pada hari ke-24) dan virulensi tinggi (hari ke-4). Perbedaan ukuran tubuh juga terlihat jelas, masing-masing 22,05 µm pada isolat virulensi rendah, 24,1 µm pada virulensi sedang, dan 24,6 µm pada virulensi tinggi. Analisis sekuensing menunjukkan bahwa isolat dengan virulensi rendah dan sedang berada dalam kelompok yang sama, sedangkan isolat virulensi tinggi berkelompok dengan isolat dari Thailand dan Tiongkok. Studi ini menunjukkan bahwa isolat T. evansi di lapangan memiliki keragaman biologis dan genetik yang cukup lebar, sehingga pemantauan terhadap penyebarannya tetap diperlukan, termasuk pada isolat yang tampak kurang virulen.

Analisis Aktivitas Nitrifikasi dari Bakteri yang diisolasi dari Rumah Burung Walet Menggunakan Metode Spektrofotometri

Fri, 05 Dec 2025 08:38:43 +0000

Nitrifying bacteria are essential in the nitrogen cycle, turning ammonia into nitrite and nitrate, which greatly contributes to the contamination of edible bird's nests in swiftlet houses. This study aims to evaluate the nitrifying activity of bacteria isolated from swiftlet housing environments in Central Kalimantan, Indonesia. A total of 16 environmental pooling samples were obtained from four different environmental sources within the swiftlet houses: faeces (n=4), pond water (n=4), edible bird’s nests (n=4), and soil (n=4). The nitrifying activity of each isolate was examined by measuring nitrite production using a spectrophotometric method and ammonium consumption using a commercial ammonium test kit. The main criteria investigated were the ability of the bacteria to oxidize ammonia to nitrite and their ability to result in ammonium reduction. The findings indicated that all 16 isolates were able to generate nitrite within a range of 4.8 to 24.7 ppm and showed considerable ammonium consumption. Among the sources, the bacteria from soil exhibited higher nitrifying activity compared to those from soil, pond water and bird’s nests. The findings indicate that the swiftlet house environment harbors diverse and active nitrifying bacteria. Furthermore, spectrophotometry method can be used as an initial detection for nitrifying bacteria.

Sat, 06 Dec 2025 01:39:01 +0000

The use of fresh semen in artificial insemination quickly leads to a decline in quality if an appropriate extender is not added. A suitable extender functions to protect spermatozoa during processing and storage, thereby prolonging their viability. Additionally, incorporating fruit juices rich in antioxidants can help neutralize free radicals and minimize cellular damage. Semen wascollected froma 2–4-year-old male pig using a dummy. High-quality semen was then divided into two control groups (K0 and K1) and five treatment groups consisting of varying volumes of cherry tomato juice: 20µL, 40µL, 60µL, 80µL, and100µL, all mixed coconut water extender and stored at preservation temperature. Sperm motility was evaluated every two hours for a total of 16 hours. The findings indicated that the coconut water extender combined with cherry tomato juice antioxidants significantly influenced (p<0.05) the motility percentageof Landrace boar spermatozoa. The addition of 60µL cherry tomato juice (Solanum lycopersicum var. cerasiforme) produced the best results in maintaining sperm quality, with a motility value of 67.00±0.79% and a viability duration of up to 16 hours.

Infection by the parasitic worm Anisakis sp. can cause anisakiasis in humans and is an important food safety concern, particularly in mackerel tuna (Euthynnus affinis). This study aimed to identify the morphology of Anisakis sp. larvae in mackerel tuna obtained from the Fish Auction Center (TPI) in Kupang, East Nusa Tenggara, using a Scanning Electron Microscope (SEM). Examination was conducted on internal organs (liver, intestine, and gonads), and the larvae found were observed using SEM. The results revealed the presence of Anisakis sp. larvae characterized by typical morphological features, including a boring tooth and papillae in the anterior part, as well as a mucron in the posterior part. These findings confirm Anisakis sp. infection in mackerel tuna and provide detailed morphological data useful for species identification and zoonosis prevention through marine fish quality monitoring.

Gonadectomy is a common procedure to control dog populations and prevent reproductive diseases. Ovariectomy (OVE) and ovariohysterectomy (OH) are the primary techniques, although their relative efficiency remains under debate. This study compared both methods based on hematological parameters, surgical duration, blood loss, wound healing, progesterone levels, body weight, and postoperative behavior in female dogs. This experiment were using 14 female domestic dogs were divided into OVE and OH groups. Surgeries were performed under general anesthesia, and outcomes were analyzed statistically. Postoperatively, hematocrit and erythrocyte counts significantly decreased in OH group (p<0.05), while white blood cell counts were higher than in OVE (p<0.05), indicating stronger inflammatory response. OVE had a shorter surgical time (56.18 ± 7.10 min vs. 84.41 ± 24.28 min), lower blood loss (4.91 ± 2.60 g vs. 46.02 ± 39.06 g), and faster wound healing (4.57 ± 0.76 days vs. 5.91 ± 1.24 days) (p<0.05). There was no significant differencs in progesterone level one month post surgery between the OVE and OH groups (0.67 ± 0.30 ng/mL and 0.48 ± 0.29 ng/mL, respectively). Likewise, no significant difference were observed in body weight gain, as well as in grooming, sleeping, drinking, exploration and play behaviours between the groups after nine weeks of observation. In conclusion, both techniques effectively reduce plasma progesterone concentration and support body weight gain, but OVE offers greater surgical efficiency, faster recovery, and fewer hematological alterations, highlighting its potential as the optimal technique for sterilizing.

This study was conducted to apply various concentration levels of complete premix (CP) as a dietary supplement in order to determine the optimal concentration for enhancing nutrient digestibility in Cross Boer goats. The results of this research are expected to provide a scientific basis for developing more effective and efficient feed formulations on farms to accelerate productivity achievement in goats, thereby supporting the Government of Indonesia’s national meat self-sufficiency program and contributing to the realization of food self-reliance as part of the Asta Cita goals. The experiment used 15 male Cross Boer goats aged 8–10 months, arranged in a randomized block design consisting of five treatments with three replications each: basal diet without CP supplementation (P0); basal diet with 0.25% CP (P1); 0.5% CP (P2); 0.75% CP (P3); and 1% CP (P4). The parameters measured were the digestibility coefficients of dry matter (DM), organic matter (OM), crude protein (CP), and crude fiber (CF). Data were analyzed using one-way ANOVA in SPSS version 24, and significant differences (P<0.05) were further examined with Duncan’s multiple range test. The results showed that treatment P1 significantly (P<0.05) affected DM, OM, and CP digestibilities. All treatments had no significant effect (P>0.05) on CF digestibility. Conclusion of this study that supplementation of complete premix up to 0.25% of the total diet could improve nutrient digestibility in Cross Boer goats.
