Abstract

This study aimed to determine the effect of the addition of encapsulated Lactobacillus bulgaricus FNCC 0035 and Streptococcus thermophilus FNCC 0040 additions on the microbiological quality, specifically the Total Plate Count (TPC), Lactic Acid Bacteria (LAB), Yeast and Mold Count (YMC), and antimicrobial activity of goat milk set yoghurt. The research was conducted using a laboratory experiment with a Completely Randomized Design (CRD) with four treatments, namely T0 (2% addition of non-encapsulated LAB starter), T1 (addition of 2% encapsulated LAB starter), T2 (addition of 3% encapsulated LAB starter), and T3 (addition of 4% encapsulated LAB starter), with four replicates each. Data analysis was performed using Analysis of Variance (ANOVA), and if there was a significant effect, it was further tested with Duncan's Multiple Range Test (DMRT). The results of the variance analysis showed that the addition of encapsulated LAB had a significant effect (P<0.05) on the microbiological characteristics of goat milk set yoghurt. Goat milk set yoghurt with the addition of 4% encapsulated LAB starter (T3) was the best treatment with an average TPC of 6.65 log cfu/ml, LAB 8.70 log cfu/ml, YMC of 1.80 log cfu/ml, antimicrobial activity against Escherichia coli bacteria of 0.90 mm, and antimicrobial activity against Staphylococcus aureus bacteria of 1.54 mm.

Abstract

Beef cattle are important livestock in Indonesia. Besides meat, beef cows also produce colostrum, which is essential for calf immunity, growth, and survival during the early postpartum period. This study aimed to analyze colostrum and colostrum milk production of Ongole Crossbred (PO, abbreviation of “Peranakan Ongole”) and Pasundan cows. The research was conducted at the Mitra Mandiri Situbolang Cooperative, Indramayu, West Java, using 21 beef cows (PO and Pasundan). Colostrum was measured on the first day postpartum, while colostrum milk was defined as transition milk from colostrum to ordinary milk and was measured on days four and seven by weighing calves before and after suckling. Feed consumption and microclimate conditions were also recorded. Data were analyzed using an independent t-test. Results showed that there was no significant difference (? > 0.05) in the production of colostrum on the first day and the production of colostrum milk on the fourth day between the two breeds. However, there was a significant difference on day seven (? < 0.05), with PO cows producing more colostrum milk than Pasundan cows (4.29 kg vs 3.70 kg respectively). PO cows showed a greater production potential than Pasundan cows under the conditions of this study.

Abstract

Given the importance of enhancing local livestock productivity, this study evaluated the phenotypic traits of Boer × Peranakan Ettawa (Boer-PE) crossbred offspring. The objective was to identify superior individuals for the development of a specialized meat-type goat lineage in Indonesia. Nineteen Boer-PE offspring, consisting of nine females and ten males, were monitored from birth to four weeks of age. Morphometric data, including body weight, body length, wither height, chest circumference, and ear dimensions, were recorded and analyzed to identify the performance of their parental breeds. The results showed that the crossbred progeny had higher average body weight and improved morphometrical attributes as compared to the native PE goats, which indicated the presence of positive heterosis. Female offspring Boer-PE goats had the average weight gain of 1.8 kg, with chest circumference of 36.86 cm, body height of 36 cm, and body length of 36 cm. Males offspring showed higher performance, with an average weight gain of 2.0 kg, chest circumference of 39.13 cm, body height of 42.25 cm and body length of 39.13 cm. These findings showed that Boer-PE crossbred goats have significant potential in the selection as the starting stock in meat type goat breeding initiatives. It is recommended to carry out further generational analysis in conjunction with molecular genetic research to confirm that the performance is stable, and that the beneficial traits are hereditary.

Abstract

The Rote horse is a local genetic resource from the Rote Ndao Regency, East Nusa Tenggara, which has important socio-cultural, ecological, and economic value to the community. However, its utilisation of Rote horses is relatively low as the rapid expansion of motorised transportation has shifted their role in traditional practices and local livelihoods. This situation may limit their contribution to the local economy and raise concerns about the conservation and long-term sustainability of this local livestock genetic resource. This study aimed to formulate a sustainable development strategy for the Rote horse using an integrated approach that considers the technical, social, and economic aspects of local livestock management. A mixed-method approach was used, involving 96 respondents through structured interviews, focus group discussions (FGDs), and participant observations. SWOT, TOWS, and QSPM analyses identified and prioritized development strategies. The study results show that the main strengths lie in the ecological adaptation of the Rote horse, cultural values (Hu's rituals), and the availability of natural resources. Weaknesses stem from limited annual feed supply and minimal technology adoption. Tourism potential and institutional support represent strategic opportunities, while policy barriers and supply fluctuations pose threats. The recommended priority strategy involves the development of eco-cultural tourism centred on the Rote horse (18.45), which achieved the highest score in the QSPM analysis. This study highlights the significance of integrating cultural values and institutional support, and of strengthening the tourism sector, as a roadmap towards a sustainable Rote horse breeding system while strengthening local economic resilience and genetic conservation.

Abstract

In this study, the effects of in ovo injection with adenosine triphosphate (ATP) on the hatching performance, body measurements, and carcass characteristics of Sentul chickens, an indigenous breed of Indonesia, were evaluated. ATP, a key nucleotide that mediates cellular energy transfer, was injected into the amniotic cavity on day 18 of incubation. Unsex 250-day-old chicks (DOCs) were subjected to two treatments: control (P1: without ATP injection) and ATP injection on the 18th day of incubation (P2). The birds were maintained in three replicates per treatment, and the cage was considered the experimental unit. During the rearing period, the birds were redistributed according to three growth stages: period I (1–14 days, 2 cages, 125 chicks per cage), period II (15–28 days, 6 cages, 30 birds per cage), and period III (29–56, 12 cages, 15 birds per cage). The data were analysed using an independent t test, and differences were considered significant at P<0.05. ATP injection slightly improved hatchability (92,8 ± 0,71) and hatching weight (33,12 ± 0,56) compared with those of the control group (91,2 ± 0,93 and 32,50 ± 0,66, respectively), although the differences were not statistically significant (p>0,05). However, compared with the control treatment, the ATP treatment significantly improved several morphometric traits, including tibia length in Period I (4,60 ± 0,40 vs, 3,78 ± 0,70; P<0.05) and wing and chest lengths across the observation periods (p<0.05). At 8 weeks of age, compared with the control group (404.50 ± 196.49 g; P < 0.05), the group receiving ATP injection had a higher carcass weight (474.58 ± 206.22 g), whereas the carcass percentage and the meat-to-bone ratio were not significantly affected (P > 0.05). These findings indicate that in ovo ATP injection may increase the skeletal growth and carcass weight of Sentul chickens without affecting hatchability or carcass composition.

Abstract

This research was conducted to determine the effect of rice husk in a corn straw silage-based ration on the performance of Garut sheep. In this study, a completely randomized design (CRD) was used to determine the effects of rice husk on performance, digestibility, and organs. In this study, different amounts of rice husk were added to a corn straw silage-based diet, and each treatment was repeated five times. Twenty-five five-month-old male Garut sheep weighing 17.13±1.65 kg were divided into 5 groups, with one sheep per repetition. Each group was given an experimental diet consisting of the following: RH0 = 60% corn straw silage + 40% rice bran + 0% rice husk, RH1 = 60% corn straw silage + 30% rice bran + 10% rice husk, RH2 = 60% corn straw silage + 20% rice bran + 20% rice husk, RH3 = 60% corn straw silage + 10% rice bran + 30% rice husk, and RH4 = 60% corn straw silage + 0% rice bran + 40% rice husk. These findings indicated that higher levels of rice husk in the diet reduced performance, body weight, and weight gain and increased the weight of the digestive tract. Overall, the addition of rice husk in this study decreased the performance

Abstract

Chicken skin, as a byproduct, can cause environmental impacts if poorly managed, even though it also has potential as a food product. Diversification of chicken skin derivatives is necessary because these materials are susceptible to spoilage from microbial activity. In recent years, chicken skin oil has been widely used in households as a cooking fat to enhance flavour and aroma. However, research on methods for producing high-quality chicken skin oil remains limited. The purpose of this study was to evaluate the effects of different rendering methods on oil yield, peroxide value, acid value, and moisture content and determine the best method on the basis of these parameters. Chicken skin was rendered using pan, oven, and microwave rendering methods, and the extracted oils were characterized using standardized analytical methods. The results of the statistical analysis indicated that compared with the other methods, microwave rendering resulted in the highest yield (21.09%) and a significantly lower peroxide value (2.18 meq O?/kg). Oven rendering demonstrated oxidative stability comparable to that of microwave rendering, despite a lower yield (13.31%). The acid value and moisture content of the various rendering techniques did not differ significantly. Microwave rendering was found to be the best dry rendering technique by the De Garmo effectiveness index, which balanced oxidative stability and yield. These results support the wider use of poultry byproducts in food applications by demonstrating that microwave rendering is an effective and promising technique for producing chicken skin oil with desired physicochemical properties.

Abstract

This study aimed to evaluate the effects of a “green concentrate” based on Azolla pinnata and Spirulina sp. on the production performance, haematological profile, physiological status, and egg lipid quality of Japanese quail (Coturnix coturnix japonica). A completely randomized design (CRD) was applied using 54 laying quails assigned to three dietary treatments: T0 (basal diet), T1 (basal diet + 10% Azolla pinnata), and T2 (basal diet + 10% Azolla pinnata + 0.1% Spirulina sp.), with six replicates per treatment. The parameters observed included production performance (egg production, egg weight, feed intake, and feed conversion ratio), haematological profile (erythrocyte, haemoglobin, haematocrit, and differential leukocyte), relative organ weight, and the egg lipid profile (cholesterol and fatty acids). The results revealed that the dietary treatments had no significant effect (P>0.05) on production performance or haematological parameters, indicating that physiological homeostasis and health status were maintained. However, numerical improvements in gizzard development and reduced liver weight were observed, suggesting the occurrence of adaptive metabolic responses. Importantly, the quality of the eggs significantly improved, as indicated by reduced yolk cholesterol and increased docosahexaenoic acid (DHA) levels in the T1 and T2 treatments. In conclusion, the inclusion of 10% Azolla pinnata combined with 0.1% Spirulina sp. can be considered a safe and effective feeding strategy to produce functional quail with improved lipid profiles without compromising performance or physiological stability

Abstract

Bali cattle, developed in Indonesia, are renowned for their high parasite resistance, adaptability, and reproductive health. This study aimed to evaluate the impact of age on the kinematic parameters of sperm in Bali bulls post-thawing. Semen samples were obtained by artificial vagina methods from three Bali bulls aged between 11 and 13 years, whose age was not indicated, and one bull of 9 years, which was used as a control. The experiment was conducted in December 2023 at the Singosari National Artificial Insemination Center in Malang, East Java, for sperm parameters, including viability, motility, and morphology. Computer-assisted sperm analysis was performed. The results showed a decline in sperm quality from fresh to frozen semen. Despite this, the semen from Bali bulls met the Indonesian National Standard, demonstrating the bulls' superior reproductive capabilities. Bulls aged 11–13 years exhibited variations in sperm quality; however, these differences may reflect individual variability rather than a consistent age-related trend. Semen from bulls aged over 10 years remain suitable for use, though regular testing is essential. Further research is needed to understand these variations and ensure optimal semen quality across different ages.

Abstract

Standard cage-free systems may not fully accommodate the active behavior of local chickens, potentially affecting welfare and productivity. This preliminary study evaluated behavior-based modifications to cage-free housing and their associations with physiological responses, behavioral expression, and egg quality in Kampung Unggul Balitnak (KUB) pullets. Sixty 20-week-old pullets were assigned to a control group (Humane Farm Animal Care [HFAC] standards) or a modified group with reduced stocking density (6–7 hens/m²), a 1:3 nest-to-hen ratio, and multi-level perches. Welfare indicators included plasma corticosterone levels (measured by enzyme-linked immunosorbent assay, ELISA) and behavioral observations. At the same time, egg quality was assessed based on physicochemical properties and microbiological safety in accordance with the Indonesian National Standard (SNI). Corticosterone levels were comparable between the modified (1.69±0.56 ng/mL) and control (1.48±0.49 ng/mL) groups. The modified housing system was associated with more frequent expression of natural behaviors, such as dust bathing and perching, and a lower frequency of aggressive interactions compared with the control system. Egg quality parameters were similar between groups, and microbiological contamination remained below SNI safety thresholds. The modified group showed a numerically higher yolk cholesterol levels (764.94 mg/100 g) than the control group (634.24 mg/100 g). In conclusion, this preliminary study suggests that behavior-based modifications to cage-free housing may enhance behavioral expression in KUB chickens without compromising egg safety. However, the findings are limited by the preliminary design and lack of experimental replication. Future replicated studies are needed to validate these observations.
