Abstract

This study investigated the impact of temperature differences on broiler chickens’ blood profiles and performance. The experiment used two thermal environments, 20°C (T20) and 30°C (T30), which represent comfortable and heat-stress conditions, respectively. An 80-DOC (day-old chick) Ross strain broiler was incubated in two broiler houses. The temperature and relative humidity were measured daily. The temperature and relative humidity were measured daily. Blood samples were collected once at the end of the fifth week, while performance measurements were recorded during the nursery and treatment periods. The data were analysed descriptively. Broiler chickens in the T20 treatment experienced ambient temperatures of 24–26°C with 74–80% relative humidity, whereas those in the T30 treatment experienced temperatures of 30–32°C with 75–78% relative humidity. The hematological values remained within normal physiological ranges: erythrocytes ranged from 3.16–3.41x106/mm3, haematocrit ranged from 25.47–27.02%, haemoglobin ranged from 10.27–10.43 g%, and leukocytes ranged from 8.65–15.40x103/mm3. Broiler chickens reared at high temperatures presented heat stress, as indicated by the ratio of heterophiles to lymphocytes being 0.59. Heat stress resulted in reduced feed consumption, lower body weight gain, decreased final body weight, and an increased feed conversion ratio.

Abstract

This study aimed to evaluate the chemical composition, in vitro fermentation characteristics, and nutrient digestibility of local forages from Biak Utara District, Biak Numfor Regency, Papua. Eleven forage species commonly consumed by ruminants were collected, combined with elephant grass (Pennisetum purpureum) at a ratio of 64.2:35.8, and incubated in vitro for 48 h in cattle rumen fluid. The chemical composition, pH, ammonia-nitrogen (NH?-N) content, volatile fatty acid (VFA) content, gas production, methane (CH?) content, and in vitro digestibility of dry matter (DMD) and organic matter (OMD) were determined. The data were analysed via ANOVA followed by Duncan’s multiple range test. The results revealed wide variation in the crude protein (13.0–25.2%) and fibre fractions (NDF 33.2–61.6%; ADF 32.0–53.8%; hemicellulose 1.2–19.3%), which significantly affected fermentation characteristics and nutrient digestibility. The NH?-N concentration (29.5–40.9 mg/100 ml) exceeded the minimum threshold required for microbial protein synthesis. The total VFA concentration ranged from 61.3 to 81.2 mM, with higher values in forages with lower fibre fractions. Total gas and CH? production also varied, with the highest values observed in combinations with Garcinia dulcis and Morinda citrifolia. These combinations also had the highest DMD and OMD values (63.2% and 62.4%, respectively), whereas Ficus recemosa yielded the lowest values. In conclusion, the nutritional quality and fermentability of local forages are strongly influenced by the balance between the crude protein and fibre fractions. Forages with lower NDF and ADF contents and adequate protein levels improved digestibility and fermentation, indicating their potential to increase ruminant productivity in Biak Numfor Regency.

Abstract

This study aimed to examine the physiological response, blood metabolites, consumption and digestibility, and carcasses of kacang goats fed Bauhinia purpurea leaves as an additive in complete feed. The study used 16 fattening goats aged 10–12 months with an initial body weight range of 12–14 kg via a completely randomized design (CRD) with 4 treatments and 4 replicates: T0: G. sepium 38% + native grass 32% + rice bran 5% + corn flour 24.8% + mineral mix 0.2% (control); T1: G. sepium 36% + native grass 34% + rice bran 5% + corn flour 22.3% + mineral mix 0.2% + B. purpurea leaves 2.5%; T2: Gliricidia sepium 34% + native grass 32% + rice bran 5% + corn flour 21.3% + mineral mix 0.2% + B. purpurea leaves 7.5%; T3: G. sepium 32% + native grass 30% + rice bran 5% + corn flour 20.3% + mineral mix 0.2% + B. purpurea leaves 12.5%. The results revealed that the treatment had no significant effect on any of the variables. The use of B. purpurea leaves in complete feed at 2.5% (T1), 7.5% (T2) and 12.5% (T3) had the same effect on the physiological response, nutrient consumption and digestibility, blood metabolites, and carcass and noncarcass production.

Abstract

Meat is an animal-based food rich in essential nutrients such as protein, fat, vitamins, and minerals. Chicken floss is a popular processed meat product in Indonesia that is enriched with spices to enhance flavour and antioxidant properties. This study aimed to evaluate the chemical characteristics of degummed red fruit oil (Pandanus conoideus L.) and its effects on the physicochemical and sensory qualities of chicken floss. Red fruit oil is a traditional functional ingredient from Papua and is well known for its high ?-carotene and tocopherol contents, which act as natural antioxidants. The study was conducted from February to August 2022. Degumming of red fruit oil was carried out at the Laboratory of Agricultural Engineering, Faculty of Agricultural Technology, University of Papua (UNIPA). Chicken floss production was conducted at the Agricultural Product Processing Laboratory, Manokwari Agricultural Development Polytechnic, while physicochemical analyses (moisture, protein, fat, total carotenoid, and total tocopherol contents) were performed at Institute pertanian Bogor (IPB) University, Bogor. The results revealed that the addition of degummed red fruit oil significantly increased the ?-carotene and tocopherol contents compared with those of the control (without oil addition), improved color intensity, and enhanced sensory acceptance in terms of color, texture, aroma, and taste. The optimum product quality was obtained at a red fruit oil concentration of 15% with a heating time of 30 minutes, which produced the highest overall sensory acceptance. Furthermore, the interaction between the oil concentration and heating time significantly influenced the overall quality of the chicken floss. These findings indicate that degummed red fruit oil has strong potential as a natural colorant and functional ingredient in meat-based products.

Abstract

This study evaluated post-thaw semen quality and the proportions of X- and Y bearing spermatozoa in Bali cattle semen sexed by albumin of bovine serum albumin (BSA) column using two different gradients. In this study, frozen semen from a Bali bull was used, with three treatments: T0 (non-sexed frozen semen as a control), T1 (BSA 5%:8%), and T2 (BSA 5%:10%). The parameters observed were individual motility, viability, abnormality, concentration, total motile sperm (TSM), and sperm proportion.  The results showed that sperm motility in the upper fraction (UF) was highest under T2 (41.57%), whereas in the lower fraction (LF) it peaked under T1 (24.15%). Sperm viability was highest in the UF under T1 (57.69%) and in the LF under T1 (39.02%). The lowest abnormality was observed in the UF under T2 (4.64%) and in the LF under T1 (7.27%). Sperm concentration reached 30.14 million/straw in the UF under T2 and 22.27 million/straw in the LF under T2. Total sperm motility (TSM) was highest in the UF under T2 (12.57 million/straw) and in the LF under P1 (4.76 million/straw). The sperm proportions of the UF reached 75% X (T1) and the LF 81.71% Y (T1). Overall, the upper fraction obtained from the 5%:8% BSA gradient provided acceptable post-thaw sperm quality and adequate X/Y sperm enrichment, supporting its suitability for artificial insemination.

Abstract

    This study aimed to evaluate the effect of combining fermented cow manure with broiler starter feed on BSF growth and reproduction. Cow manure was fermented for 7 days using EM4 and molasses, then mixed with broiler feed at ratios of T0 (100% manure), T1 (75:25), T2 (50:50), T3 (25:75), and T4 (100% feed). A Complete Random Design with three replicates was used in this study. Growth parameters (weight, length, and width of larvae) were observed on days 14, 21, and 28, while reproductive parameters included egg diameter, hatchability, and quality of early larvae. The results showed that an increase in feed proportion significantly improved larval growth (p < 0.05), with T4 providing the best results. The egg size did not differ significantly, but T4 had the highest hatchability (98.2%). Improved nutrient availability enhances females' energy reserves and promotes ovarian development. Fermentation also improves nutrient digestibility and the substrate's attractiveness for oviposition. The addition of broiler feed to fermented cow manure can improve the growth and reproductive performances of BSF, therefore, it could support a more productive and sustainable cultivation system.

Abstract

Beef has become one of the main protein sources for urban households. Following the 2022 Foot and Mouth Disease (FMD) outbreak, consumers may adjust purchasing and consumption behavior due to heightened food-safety risk perceptions and disruptions in the beef supply chain. This study examines how the FMD outbreak, together with household socio-economic characteristics, relates to changes in urban beef consumption. The study was conducted in Malang City using surveys of 100 household respondents who consume beef. The data were analyzed descriptively, with a before-and-after FMD comparison and multiple linear regression with a natural log model for the factors affecting demand. The study's findings confirmed that FMD significantly decreased several consumption-related indicators, including the frequency and volume of beef purchases, as well as the mode of purchase, with a shift from traditional to modern markets and even to e-commerce. Beef consumption generally continued, but households adopted more risk-moderated patterns. Regression results suggest that household size, income, and education are key correlates of beef demand during the outbreak, whereas beef price and prices of alternative proteins show limited explanatory power in this sample. This study contributes empirical evidence on outbreak-driven demand adjustment and channel switching among urban consumers. The findings imply that strengthening food-safety communication, traceability, and consumer education may help stabilize demand and support safer purchasing decisions during future animal-disease events.
