Abstract

This research aims to determine the quality of spermatozoa in the sexed semen that separated using the Percoll Density Gradient Centrifugation (PDGC) method with various gradients using egg yolk tris aminomethane diluent. The study was conducted at the Singosari Artificial Insemination Center from December 2023 to February 2024. The study's material was the semen of one Bali bull with individual motility ? 70%. The experimental design used a Randomized Group Design with the sexed semen PDGC method treatment: T1 = 10 gradients, T2 = 5 gradients, and T3 = 3 gradients, each with ten replications. The analysis showed that the gradient variations significantly impact the individual motility on the bottom layer of sexed semen (P<0.05). Conversely, gradient variance did not affect viability, abnormality, concentration, total motile spermatozoa, and individual motility on the top layer of sexed semen (P>0.05). In conclusion, sexed semen using the PDGC method with varied gradients is suitable for the freezing process due to its high quality.

Abstract

Colibacillosis remains a prevalent issue in breeder superior native chickens (KUB). This study aims to isolate, characterize, and assess the antimicrobial susceptibility of E. coli from breeder KUB chickens in Yogyakarta, Indonesia. Samples, including infertile eggs (n=113), day-old chick (DOC) deaths (n=53), drinking water (n=17), feed (n=25), eggshells (n=117), and fluff (n=113), were collected through random sampling from breeder KUB chickens. Isolation and identification of E. coli were carried out via biochemical methods, whereas serological tests were performed with antisera for O1:K1, O2:K1, and O78:K80. Hemolytic E. coli strains were identified through culture on blood agar, and antimicrobial susceptibility was evaluated via the disk diffusion method. A total of 31 E. coli isolates were obtained from various sources: infertile eggs (15.04%), DOC-contaminated eggs (13.20%), drinking water (35.29%), feed (8.00%), eggshells (8.00%), and fluff (20.25%). Among the isolates, 22.62% were hemolytic, and 77.38% were nonhemolytic. The serotype distributions were as follows: 11.9% O1:K1, 9.52% O2:K1, and 9.52% O78:K80. E. coli isolates were susceptible to tetracycline, oxytetracycline, enrofloxacin, and sulfamethoxazole but resistant to ampicillin, streptomycin, and erythromycin. E. coli, the causative agent of colibacillosis, has been isolated from KUB breeder chickens in Yogyakarta. Therefore, strengthening biosecurity measures and implementing effective antibiotic management strategies are crucial for mitigating the risk of antibiotic resistance.

Abstract

Consumers’ preferences for beef are influenced by the interplay of intrinsic and extrinsic attributes, which affect their purchasing decisions and willingness to pay. Therefore, this study aimed to identify the key attributes influencing consumers’ purchasing power for beef in both traditional and modern markets in Samarinda City. The research was conducted in various markets in Samarinda City, East Kalimantan Province, including traditional markets (Segiri, Ijabah, Kedondong, and Rahmat) and modern markets (Hypermart Bigmall, Farmers Market Mall SCP, Foodmart Mall Lembuswana, and Lotte Grosir), using a questionnaire-based interview method. A total of 80 respondents, comprising 51 women and 29 men, were selected through purposive sampling. Primary data were collected through interviews and questionnaire responses. These were analyzed using chi-square tests and descriptive methods to assess consumers’ preferences for beef product attributes. The results showed that consumers in both traditional and modern markets preferred dark red beef with low-fat content and classified as Group One commercial cuts. The dark red beef with low-fat content is perceived as fresher and healthier (due to the lower number of calories and higher protein levels). The chi-square analysis indicated significant differences in consumers’ preferences for beef attributes between traditional and modern markets in Samarinda City, East Kalimantan Province.

Abstract

Full fat mayonnaise raises consumer concerns about degenerative diseases such as high cholesterol and obesity, increasing the demand for reduced fat alternatives. However, reduced fat mayonnaise often results from emulsion instability due to the lower oil content. Adding natural stabilizers such as aloe vera powder (AVP) can improve emulsion stability and increase viscosity. This research aimed to determine the optimal percentage of Aloe vera powder to enhance the physicochemical and sensory qualities of reduced fat mayonnaise (RFM). The materials used were reduced fat mayonnaise made from canola oil, vinegar, yolk, sugar, salt, pepper, and mustard, with 2%, 4%, and 6% aloe vera powder. The experimental laboratory method used was a completely randomized design (CRD) with 4 treatments and 5 replications. The data were analysed via ANOVA, followed by Duncan's multiple range test (DMRT). The results of this research revealed that aloe vera powder decreased the moisture content (20.52–23.72%) and pH (3.78–4.50) but increased the acidity (0.18–0.45%), viscosity (3006–3874 cps), and emulsion stability (95.50–95.95%) and was accepted and liked by the panellists. The results indicate that the addition of 6% Aloe vera powder can act as a fat replacer and provide the best reduction in fat mayonnaise on the basis of physicochemical quality and sensory evaluation.

Abstract

Foot and mouth disease (FMD) poses significant threats to livestock production systems globally, particularly cloven-hoofed animals. Indonesia's recent FMD outbreak, following 35 years of disease-free status, created substantial economic challenges for the dairy sector. Despite the scale of the outbreak, limited research has focused on its specific financial impacts on smallholder dairy farms, creating a critical knowledge gap for effective policy development. This study analyses the financial impact of foot and mouth disease (FMD) on dairy farming, focusing on changes in revenue, costs, and profitability before and after the outbreak. Through descriptive and input?output analysis, economic losses were quantified on the basis of structured surveys and secondary data from affected dairy farmers. The findings indicate that the FMD significantly reduced milk production revenue (-8%) while increasing overall farm costs (+6%), leading to a drastic 84% decline in farm profits. Increased spending on veterinary treatments, feed supplementation, and transportation further exacerbated financial instability, whereas a slight increase in livestock sales (+11%) served as a short-term coping mechanism. These results highlight the need for enhanced disease control measures, financial assistance programs, and policy interventions to support affected farmers. Implementing effective vaccination strategies, improving biosecurity protocols, and establishing government-backed economic relief programs can mitigate the financial burden of FMD on the dairy sector. This study contributes to the limited literature on the economic consequences of livestock disease outbreaks in Indonesia and emphasises the need for long-term resilience strategies to sustain dairy farm profitability and stability in disease-prone regions.

Abstract

The growing concern regarding excessive sugar intake and its link to chronic health conditions has driven innovations in functional food development, particularly through the use of natural sugar alternatives. This study aimed to investigate the effects of substituting sugar with inulin-enriched honey powder on physical, sensory, and microstructural characteristics, as well as selected chemical properties (moisture and ash) of prebiotic biscuits. A laboratory experiment with a completely randomized design with five treatments and four replications was conducted. Biscuits were formulated with varying ratios of powdered sugar and inulin honey powder: 100:0, 75:25, 50:50, 25:75, and 0:100. The measurements included diameter, thickness, spread ratio, hardness, color (L*, a*, b*), sensory attributes (color, aroma, taste, hardness, overall acceptance), and microstructure by scanning electron microscopy. The results revealed that increasing the proportion of inulin honey powder significantly (P < 0.01) reduced the diameter and thickness but improved the spread ratio. The 50:50 sugar-to-honey powder ratio presented the best combination of physical characteristics and sensory acceptance. Biscuits from this formulation had a favourable spread ratio, lower hardness, and a homogeneous microstructure. Sensory evaluation indicated that moderate substitution preserved desirable taste and hardness. These findings demonstrate that inulin honey powder can serve as a viable natural sweetener in baked goods while improving textural and structural quality. This approach contributes to the development of healthier food options and supports future applications of natural prebiotic sweeteners in functional bakery products.

Abstract

The increasing demand for edible bird nests (Aerodramus fuciphagus) has raised concerns regarding the sustainability of swiftlet populations. Artificial incubation is a potential solution to mitigate the impact of nest harvesting on wild populations. This study aimed to examine the morphological characteristics of swiftlet eggs from Buntok, Central Kalimantan, and their hatchability under controlled incubation. The 240 fertile eggs from a total of 400 eggs were incubated at 33–34.5°C with 70–80% humidity, and hatchability rates were assessed. The results indicated that swiftlet eggs had an average weight of 1.74 ± 0.151 g, length of 2.01 ± 0.090 cm, and width of 1.29 ± 0.038 cm. Descriptive analyses (means ± standard deviations) were performed for egg morphology parameters. Correlation analysis (Pearson’s correlation coefficient) was conducted to examine the relationships between egg characteristics and hatchability. Statistical analysis revealed a weak but significant correlation between egg weight and hatchability (p = 0.041), whereas egg length and width had no significant effect. Oval-shaped eggs had a slightly higher hatch success rate (62.5%) than elongated eggs did (60.0%). Hatchability was significantly influenced by incubation conditions, with stable temperature and humidity levels increasing embryonic survival. Regular egg turning (six times per day) improved hatch success, which aligns with findings in other avian species. These results contribute to swiftlet conservation and sustainable farming by optimizing artificial incubation protocols.

Abstract

Red rice exhibits high antioxidant activities due to its significant levels of anthocyanins. Incorporating red rice into milk dodol production is expected to enhance product functionality. This research examined the effect of substituting glutinous rice flour with red rice flour at varying proportions on the quality of steamed milk dodol. The study employed a completely randomized design with a single factor (proportions of red rice flour to glutinous rice flour: 30:70, 40:60, and 50:50). Each treatment was replicated three times. Quality parameters included anthocyanin content, antioxidant activity, TBA value, proximate composition, reducing sugar content, color values (L*, a*, b*), water activity, and sensory quality. Increasing the proportion of red rice flour significantly increased (p<0.01) anthocyanin levels, antioxidant activity, reducing sugar content, and redness (a*), but significantly decreased (p<0.01) water content, fat content, and yellowness (b*). No significant differences (P<0.05) were observed in TBA value, protein content, ash content, brightness (L*), water activity, and sensory quality with increasing red rice flour proportion. Thus, substituting up to 40% glutinous rice flour with red rice flour improved the quality and functionality of steamed milk dodol without compromising acceptability.

Abstract

The utilization of saline land for Indigofera zollingeriana cultivation is an opportunity to develop livestock in coastal areas. Salinity in coastal areas influences plant growth, particularly in the initial growth stages, because high salinity levels inhibit the uptake of both water and nutrients from the roots so that the plants will dry out. The objectives of this study were to evaluate the effects of various doses of gamma irradiation and NaCl stress on the early growth of Indigofera zollingeriana Mutant-2 seeds via a complete randomized design (CRD) with a 2x5 factorial pattern with 3 replications. The factors were salinity stress and irradiation dose. The first factor was salinity stress, which consisted of 0 mM NaCl and 40 mM NaCl. Second, the irradiation doses were 0 Gy, 50 Gy, 100 Gy, 150 Gy, and 200 Gy. The research results were analysed via analysis of variance (ANOVA), and significantly different treatments were evaluated via the DMRT test via the SAS Studio program. There was a significant difference in the effects of irradiation dose and NaCl stress on the germination rate, germination rate, mortality rate, radicle length, and plumula length, but the results were not significant for the seedling height, stem diameter, root length, number of cotyledons, or number of leaves. The DMRT results revealed that Indigofera treated with irradiation at a dose of 200 Gy had better germination rates, mortality rates, radicle rates, and plumula rates under both salinity stress conditions and gamma ray doses.

Abstract

The pellets were produced from peanut straw (PTS), water spinach (WSP), Leucaena leucocephala leaves (LLL), Gliricidia sepium leaves (GSL), and Calliandra calothyrsus leaves (CCL). Each feedstuff was pelletized with the addition of 8% tapioca flour as a binder. The pellets were tested for chemical characteristics, physical appearance, and physical characteristics, which included the pellet length, density, stacking density, stacking compaction density, modulus of uniformity, modulus of fineness, pellet durability index (PDI), and water absorption. The data were analysed descriptively. The results of this research revealed that the nutritional composition of the pellets followed that of the raw feedstuff. All the pellets varied in color depending on the color of the raw material and had a medium texture. Each pellet had specific physical characteristics. The colors of PTS, LLL, GSL, and CCL were dark green, whereas WSP was dark brown. All single pellets had a medium texture, with PDI values above 97% and MF values greater than 4.1, which classified them into the coarse group. In terms of water absorption, the CCL had the longest absorption time, approximately 75.17 minutes, whereas the other pellets had absorption times less than 30 minutes. As a result, although a single feed ingredient can be produced as pellets, the physical and chemical qualities depend on the origin of the ingredient.
