Abstract

This study evaluates the morphometric characteristics of female Peranakan Ongole (PO) cattle in Napis Village, Bojonegoro Regency, East Java, as part of a strategy for developing sustainable village breeding centers. The selection of the research location was conducted through purposive sampling, and the material in this study consists of female Peranakan Ongole cattle with age criteria (PI) based on the SNI for Peranakan Ongole cattle, namely PI0 (aged <1 year), PI2 (1 – 1.5 years), PI4 (1.5 - 2 years), PI6 (2 – 3 years), PI8 (aged > 3.5 years). Measurements include body height, body length, hip height, chest depth, chest circumference, ossa cervical vertebrae, ossa thoracic vertebrae, ossa vertebrae lumbar, ossa scapula, hip width, head length, head width and body weight, as well as morphometric indices such as head index, height slope, body index, index of compression, conformation index, length index, body ratio, proportionality and thoracic development on 206 female cattle grouped by age (PI0-PI8). Data were analyzed using multivariate analysis of variance (MANOVA) and post hoc tests, as well as key indices to identify growth patterns and body size stability. The research results show a significant increase in body size in the young-to-adult age group, where adult cows reach size stability. The morphometric index reveals consistent proportional development in the body of cattle as they age, reflecting structural maturity. Evaluation based on the Indonesian National Standard (SNI) shows that most cattle are in Class II and III, indicating excellent body quality in the productive age group. This research emphasizes that morphometric characteristics are important indicators in determining optimal management strategies to support the sustainability of local PO cattle development. These findings provide a foundation for the maintenance and development programs of the PO cattle population by prioritizing quality livestock management, supporting the conservation of local genetic resources, and enhancing cattle productivity in Indonesia.

Abstract

The livestock sector is one of the potentials in Indonesia, including duck farming. The duck population in Kediri District in 2022 amounted to 367,987 heads. This research was conducted in 5 subdistricts in Kediri District including Mojo Subdistrict, Ringinrejo Subdistrict, Wates Subdistrict, Ngasem Subdistrict, and Gampengrejo Subdistrict. The variables observed in this research include quantitative traits (femur length, tibia length, shank length, shank circumference, wing length, sternum length, chest width, and chest depth). The differences in the results of this study are influenced by environmental factors and genetics. The conclusion of this study is that the morphometric measurement interval (quantitative traits) of local ducks in each sub-district in Kediri District varies greatly because it is influenced by several factors including the environmental conditions of each sub-district, feed consumption, maintenance methods, and age. The measurement results show that local ducks in Kediri District are still cultivated by farmers and have a variety of sizes. The suggestion of this research is that morphometric measurements (quantitative traits) of local ducks should be carried out in all sub-districts in Kediri District so that it can be known that the body size of ducks in Kediri District is very diverse.

Abstract

This study evaluated the effects of pre-hatch thermal programming on internal organ development of crossbred chickens in the first week post-hatch. A total of 200 fertile eggs from a crossbreed of male local chickens and commercial laying hens were used in this study. The average egg weight was 62.76 ± 4.40 g with a coefficient of variation was 7.01%. The eggs were randomly distributed into four treatment groups, each with five replicates (10 eggs per replicate). The treatments were T0: standard incubation maintained at 37.50°C throughout the entire incubation period (control); T1: standard incubation with a 6-hour daily increase to 38.50°C from days 10-18, T2: standard incubation with a 6-hour daily increase to 39.50°C from days 10-18, and T3: standard incubation with a 6-hour daily increase to 40.50°C from days 10-18. After hatch, the chicks were reared for a week and evaluated for internal organ development. The results showed that there were no significant differences among treatments (P>0.05) for all measured variables, including the absolute weights (g) and relative percentages (%) of the internal organ. The absolute weight of the heart, liver, proventriculus, gizzard, and intestine were ranged from 0.69 to 0.84, 2.68 to 2.93, 0.74 to 0.87, 6.48 to 7.05, and 7.94 to 8.42 g, respectively. Whereas, the relative weight of the heart, liver, proventriculus, gizzard, and intestine were ranged from 0.89 to 1.12, 3.46 to 3.79, 0.95 to 1.13, 8.29 to 9.11, 10.24 to 10.82%, respectively. It could be concluded that pre-hatch thermal programming can be considered a safe strategy without compromising internal organ development of crossbred chickens in the early post-hatch period.

Abstract

Egg yolk pigmentation is a crucial quality attribute influencing consumer preference and market value. This study evaluated the effects of Canthaxanthin supplementation on yolk pigmentation and laying performance in late-stage laying hens (84–88 weeks old). A total of 180 Isa Brown hens were assigned to three dietary treatments: a control group (T0: commercial feed), a low Canthaxanthin supplementation group (T1: commercial feed + 60 g/ton feed Canthaxanthin), and a high supplementation group (T2: commercial feed + 120 g/ton feed Canthaxanthin). The data were analyzed using SPSS software (version 25.00), and a one-way analysis of variance (ANOVA) was performed to assess the effects of Canthaxanthin supplementation on laying performance and egg quality, with significance set at p<0.05. Duncan’s multiple range test was used post hoc to identify significant differences between treatment groups. Egg production performance, egg mass, feed conversion ratio, and yolk quality were assessed over a five-week period. Results indicated that Canthaxanthin supplementation significantly improved yolk color, with the highest color score recorded in T2. While egg production and feed efficiency remained unaffected, egg mass increased significantly in the supplemented groups (p<0.05), suggesting improved nutrient deposition. Additionally, feed intake was slightly higher in the high supplementation group. These findings confirm that Canthaxanthin is an effective dietary additive for enhancing yolk pigmentation while maintaining production efficiency in aging hens. The study highlights the potential economic benefits of Canthaxanthin supplementation in meeting consumer demand for well-pigmented eggs. Future research should explore its long-term effects on oxidative stability, egg lipid composition, and potential synergies with other dietary antioxidants to optimize poultry nutrition strategies.

Abstract

Eksreta puyuh merupakan sisa proses pencernaan dan ekskresi puyuh yang masih kaya akan bahan organik. Maggot Black Soldier Fly (BSF) merupakan jenis serangga yang mampu berperan sebagai agen pengomposan bahan organik. Tujuan penelitian ini untuk mengetahui komposisi nutrien maggot BSF yang berasal dari proses biokonversi kotoran puyuh yang tidak difermentasi dan difermentasi. Penelitian ini dilakukan secara sistematis melalui beberapa tahap, yaitu persiapan media pertumbuhan, biokonversi ekskreta, pemanenan, pengeringan dan penggilingan maggot, serta analisis nutrien. Rancangan acak kelompok digunakan dalam penelitian ini, dengan faktor perlakuan terdiri dari media kotoran yang tidak difermentasi (MTF) dan media kotoran yang difermentasi (MDF). Data yang dikumpulkan dianalisis menggunakan analisis ragam dengan aplikasi Minitab 19. Kandungan protein kasar tertinggi ditemukan pada perlakuan kotoran yang tidak difermentasi (MTF) sebesar 41.86%, sedangkan perlakuan kotoran yang difermentasi memiliki kandungan sebesar 38.66%. Selain itu, kandungan Beta-N dalam tepung BSF pada MDF lebih tinggi dibandingkan MTF, dengan nilai masing-masing sebesar 13.18% dan 10.79%. Lebih lanjut, tepung larva BSF yang diberi perlakuan MDF menunjukkan proporsi asam palmitat yang lebih tinggi (15.86%) dibandingkan MTF, serta kadar asam laurat yang lebih rendah (11.73%), yang berbanding terbalik dengan larva yang diberi perlakuan MTF. Selain itu, biokonversi ekskreta oleh maggot BSF terbukti menghasilkan kadar asam amino non-esensial yang tinggi pada asam glutamat, asam aspartat, dan glisin pada kedua kelompok perlakuan. Sementara itu, BSF yang diberi perlakuan MTF mengandung kadar asam amino esensial tertinggi pada leusin, lisin, dan isoleusin, dengan persentase masing-masing 2.03%, 1.79%, dan 1.16%. Hasil penelitian menunjukkan bahwa produksi maggot BSF dari kotoran yang tidak difermentasi maupun difermentasi menghasilkan nilai nutrisi yang tinggi dan berpotensi dijadikan sebagai bahan pakan ataupun komponen untuk industri lainnya.

Abstract

Feather pecking (FP) is a behavioral issue commonly found in cage-free laying hen systems, particularly in 86-week-old hens, often leading to injuries, stress, and even death. This study aimed to evaluate the effect of mineral blocks as environmental enrichment on reducing FP behavior and improving production performance. A total of 4,800 Isa Brown laying hens were assigned to four treatment groups: P0 (no mineral block), P1 (1 block), P2 (2 blocks), and P3 (3 blocks). Observations included feather pecking frequency, feather condition, mortality and morbidity rates, body weight, and feed consumption. The results showed that the use of mineral blocks significantly reduced FP behavior, with the lowest frequency observed in the P3 group. Mortality and morbidity due to cannibalism were also reduced in groups receiving blocks. Body weight was more stable and tended to increase in enriched groups. The provision of mineral blocks, composed of calcium carbonate, molasses, sodium chloride, mono-sodium phosphate, magnesium oxide, calcium oxide, mineral oil, and sulfur, proved effective in supporting natural pecking behavior and improving poultry welfare. The study concludes that mineral blocks can be a practical strategy to reduce FP and enhance the productivity and welfare of aging laying hens in cage-free systems.
