This systematic review analyzes various innovative business models designed to align livestock production with the principles of sustainable development. The models examined include the circular economy, Integrated Crop-Livestock Systems (ICLS), Precision Livestock Farming (PLF), digitally-enabled value chains (blockchain and e-commerce), and modern cooperatives. The analysis reveals that these models contribute significantly to the three pillars of sustainability—economic, social, and environmental. They achieve this by transforming waste into valuable resources, enhancing resource efficiency, improving productivity and animal welfare, and empowering smallholder farmers. The key finding is that no single model offers a universal solution; instead, the future of sustainable livestock production lies in integrated, context-specific approaches that combine technological innovation with inclusive social structures. This review concludes by emphasizing the need for policies and investments that support the adoption of these hybrid models to build a livestock sector that is productive, equitable, and environmentally responsible</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Arif Rahman Azis Azis, Woki Bilyarohttps://ejournal.unib.ac.id/buletin_pt/article/view/42634Pengaruh Penambahan Daun Kacang Tujuh Jurai (Phaseolus Lunatus, L) Fermentasi dalam Air Minum terhadap Performa Broiler.2025-09-27T00:36:26+00:00Farhan Farhanfarhanfarhan050720@gmail.comDebby syukrianidsyukriani79@gmail.comNelzi Fatdsyukriani79@gmail.comNilawatidsyukriani79@gmail.comToni Malvindsyukriani79@gmail.com<p>This study aimed to evaluate the effects of fermented kacang tujuh jurai (seven-branched peanut) leaf (DKTJF) supplementation in drinking water on the performance of broiler chickens, and to determine the most effective inclusion level. The leaves are known to contain various bioactive compounds, including alkaloids, terpenoids, flavonoids, steroids, saponins, phenolic compounds, and pheromones. The experiment was carried out over three months at the Nutrition and Feed Technology, Animal Production, Quality Testing, and Analysis Laboratories of the Payakumbuh State Agricultural Polytechnic. The materials used for preparing the treatment solution included 2 kg of fermented kacang tujuh jurai, 1 liter of EM4, 1 liter of molasses, and water. The materials used for broiler maintenance included day-old chicks (DOC), DKTJF, corn, soybean meal, minerals, coconut oil, fish meal, rice bran, and commercial feed. The equipment used for the treatment application included cages divided into 20 units (0.5 m × 0.5 m). A completely randomized design (CRD) was used, consisting of five treatment groups with four replications each, totaling 20 experimental units. Each unit contained four day-old chicks (DOC), resulting in a total of 80 broiler chickens. The treatments included DKTJF in the drinking water at 0%, 0.5%, 1%, 1.5%, and 2% levels. Observed parameters included body weight gain, feed intake, feed conversion ratio (FCR), water intake, and broiler performance index. The results showed that DKTJF supplementation significantly (P<0.05) affected body weight gain and water intake, but had no significant effect (P>0.05) on feed intake, FCR, or performance index. In conclusion, supplementation of up to 2% DKTJF in drinking water did not alter feed efficiency or overall performance, but it improved growth and reduced water consumption. The optimal inclusion level was identified at 1.5%.</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Farhan Farhan, Debby syukrianihttps://ejournal.unib.ac.id/buletin_pt/article/view/44789Kepuasan Peternak Ayam Broiler Pada Sistem Kemitraan di Kecamatan Padang Jaya Kabupaten Bengkulu Utara2025-09-25T23:52:18+00:00Indah Tri Lestaritrilestari240103@gmail.comUrip Santosouripsantoso60@gmail.comYurike Yurikeyurike@unib.ac.id<p>This study aims to analyze the level of satisfaction of broiler chicken farmers with the partnership system in Padang Jaya District, North Bengkulu Regency. The partnership system is one of the livestock business patterns that is growing rapidly in this area, where the partner company provides livestock production facilities (sapronak), technical assistance, and collects the harvest, while the farmers as plasma are responsible for maintenance. The research method used a quantitative descriptive approach with a survey technique on a number of plasma farmer respondents who are members of the partnership. Data were collected through questionnaires, interviews, and observations, then presented in tabular form and analyzed descriptively. The results showed that farmer satisfaction with the broiler chicken partnership system had the highest average value in the first place, namely in the economic capital variable (94%) because the farmers do not require too much capital, the company provides capital such as feed, seeds (DOC), as well as medicines and vaccines. Meanwhile, the lowest average value was found in distribution (77%) because the farmers are already bound by contracts with the company so they do not have freedom, selling prices are set unilaterally, irregular harvest scheduling, a less efficient harvesting system, and lack of involvement in every decision. These findings indicate that improving the quality of partnership services and transparency of collaboration can increase satisfaction and the sustainability of broiler chicken partnership patterns in Padang Jaya District.</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Indah Tri Lestari, Urip Santoso, Yurike Yurikehttps://ejournal.unib.ac.id/buletin_pt/article/view/42198Pendekatan Inovatif dalam Manajemen Ternak: Analisis Perbandingan Good Farming Practices (GFP) dan Inseminasi Buatan (IB) Berbasis Biologi Molekuler2025-09-26T06:48:33+00:00Dhea Nickydheanicky650@gmail.comDewi Mustikaningtyasdheanicky650@gmail.comYustinus Ulung Anggraitodheanicky650@gmail.com<p>Livestock farming is an important sector in meeting the food needs of the community, especially for animal protein from meat and dairy products. Although livestock farming has great potential, livestock productivity still faces significant challenges, including inadequate husbandry systems, technological limitations, and a lack of understanding of reproductive management. In an effort to improve productivity, two approaches that can be applied are Good Farming Practices (GFP) and Artificial Insemination (AI) based on molecular biology. GFP includes principles of feed management, sanitation, livestock health, and a good environment, which are expected to improve livestock welfare and the quality of production results. On the other hand, IB uses advanced technology to improve the genetic quality of livestock and enhance reproductive efficiency, particularly with the integration of molecular biology techniques. This study aims to compare the effectiveness of both approaches in improving livestock productivity. By applying GFP and IB synergistically, it is hoped that the increasing market demand can be met without neglecting animal welfare aspects.</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Dhea Nicky Nickyhttps://ejournal.unib.ac.id/buletin_pt/article/view/44842Pengaruh Penambahan EM4 dalam Fermentasi Solid Kelapa Sawit terhadap Kualitas Nutrisi Bahan Pakan2025-09-25T23:45:47+00:00Kade Wahyu Saputrikade.wahyu@gmail.comNur’aini Nur’ainikade.wahyu@gmail.comNining Suningsihkade.wahyu@gmail.comMuhammad Hakimkade.wahyu@gmail.com<p>This study aims to evaluate the effect of the addition of Effective Microorganisms-4 (EM4) on changes in the proximate composition of palm oil solids during the fermentation process. The study design used EM4 treatments with different concentrations (0%, 0.5%, 1.0%, and 1.5% stored for 14 days. The parameters observed included moisture, ash, protein, fat, and crude fiber content. The results showed that moisture and ash content tended to decrease with increasing EM4 concentration and fermentation time. Protein content decreased significantly in the EM4 treatment compared to the control, indicating the utilization of organic nitrogen by microorganisms. Conversely, fat content increased in the 1.5% EM4 treatment, presumably due to the activity of lipolytic enzymes and microbial lipid biosynthesis. Crude fiber content showed a decreasing trend in the EM4 treatment, reflecting the degradation of cellulose and lignin by cellulolytic enzymes. Overall, the addition of EM4 can improve the nutritional quality of palm oil solids by reducing crude fiber and complex proteins and increasing the fat fraction at certain concentrations, so it has the potential to be used as an alternative feed ingredient for poultry</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Kade Wahyu Saputri, Nur’aini Nur’aini, Nining Suningsih, Muhammad Hakimhttps://ejournal.unib.ac.id/buletin_pt/article/view/42506Pengaruh Penambahan Enkapsulasi Ekstrak Daun Afrika (Vernonia Amygdalina) dalam Air Minum terhadap Performa Broiler2025-09-27T00:46:33+00:00Abel Siagianabelsiagian2@gmail.comNelzi Nelzinelzifati@email.comWahyu Arisyanelzifati@email.com<p>The purpose of this study was to determine how broiler performance with the addition of African leaf extract (Vernonia amygdalina) encapsulation in drinking water affects broiler performance, including feed consumption, body weight gain, ration conversion, and drinking water consumption. This study used a Completely Randomized Design (CRD) method with five treatments (A = control, B = EEDA 0.5%, C = EEDA 1%, D = EEDA 1.5%, and E = EEDA 2%) and four replications, each consisting of five chickens. Encapsulation was carried out using the foam mat drying method with Tween 80 and maltodextrin coating materials. The results showed that the addition of African leaf extract encapsulation contributed significantly (P <0.05) to increasing feed conversion efficiency and body weight gain, as well as to decreasing feed and drinking water consumption. The addition of EEDA in drinking water affected body weight gain, feed consumption, feed conversion, and drinking water consumption. The addition of 0.5% EEDA in drinking water is the best dose that can increase body weight, ration consumption, and improve ration efficiency.</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Abel Siagian Siagian, Nelzi Fati Nelzihttps://ejournal.unib.ac.id/buletin_pt/article/view/45039Analisis Minat Peternak terhadap Usaha Ternak Sapi Potong di Kecamatan Senyerang Kabupaten Tanjung Jabung Barat2025-10-24T23:37:28+00:00ikhfa ikhfaikhfamurdi@gmail.comFatati Fatatiabubakarfatati@gmail.comIndra Sulaksana Indraindrasulaksana@unja.ac.id<p>Beef cattle farming is a crucial sector that substantially influences increasing rural household income.In Senyerang District, Tanjung Jabung Barat Regency, this potential has not been fully optimized.Several obstacles still persist, including limited capital access, feed availability, government support,land resources, and prevailing sociocultural conditions within the community. Therefore, it isnecessary to assess the extent of farmers’ interest in managing beef cattle farming. This study aims todescribe the level of farmers’ interest in beef cattle farming by analyzing six key aspects: economicvalue, capital, feed, land, sociocultural factors, and the role of government. The research was carriedout in April 2025 using a survey method with a descriptive quantitative approach. Data were collectedthrough questionnaires based on a Likert scale (1–3) and analyzed descriptively. A total of 52respondents were selected through purposive sampling, with the criterion of having receivedgovernment cattle assistance between 2010 and 2025. The study results indicate that the farmers’level of interest is categorized as high. Economic value, ease of feed acquisition, and land availabilitywere the most positively perceived factors. The long-established tradition of livestock rearing in thecommunity also contributes to the sustainability of this activity. However, some farmers still facechallenges related to capital. In conclusion, farmers in Senyerang District show a strong interest indeveloping beef cattle farming. These findings are expected to serve as a reference for relevantstakeholders in identifying regional potential and supporting sustainable livestock development.</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 ikhfa ikhfa, Fatati Fatati, Indra Sulaksana Indrahttps://ejournal.unib.ac.id/buletin_pt/article/view/45540Pengaruh Penggunaan Tepung Maggot (Hermetia illucens) dalam Ransum terhadap Kualitas Karkas Ayam Petelur Jantan Belah Empat2025-10-26T05:13:47+00:00Kususiyah Kususiyahkususiyah@unib.ac.idEmzelina Sary Damanikkususiyah@unib.ac.idDesia Kaharuddinkususiyah@unib.ac.idAnggun Marisakususiyah@unib.ac.id<p>This study aimed to evaluate the effect of maggot meal (<em>Hermetia illucens</em>) inclusion in the diet on the carcass quality of quartered male layer chickens. A Completely Randomized Design was used, consisting of four treatments with five replications, each replication using eight Lohmann Brown male layer chickens. The treatments differed in the inclusion levels of maggot meal: 0% (P0), 4% (P1), 8% (P2), and 12% (P3). Observed variables included slaughter weight, carcass weight, carcass percentage, abdominal fat percentage, meat color, meat bone ratio, cooking loss, and drip loss. Data were analysed using Analysis of Variance, and significantly different results (P<0.05) were further tested using Duncan’s Multiple Range Test to determine differences among treatments. The results showed that maggot meal inclusion had no significant effect (P>0.05) on carcass percentage, abdominal fat percentage, meat bone ratio, and drip loss. However, it significantly affected (P<0.05) slaughter weight, carcass weight, meat color score, and cooking loss. Slaughter weight, carcass weight, and meat color scores in P0, P1, and P2 were higher than in P3, while cooking loss in P0, P1, and P2 was lower than in P3. It can be concluded that maggot meal inclusion up to 8% does not reduce the carcass quality of quartered male layer chickens, whereas 12% inclusion decreases slaughter weight, carcass weight, and meat color score, and increases cooking loss without affecting drip loss.</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Kususiyah Kususiyah, Emzelina Sary Damanik, Desia Kaharuddin, Anggun Marisahttps://ejournal.unib.ac.id/buletin_pt/article/view/45531Peran Genetika pada Sifat Mengeram sebagai Dasar Seleksi pada Ayam Lokal2025-10-26T00:25:52+00:00Woki Bilyarowokibilyaro@unib.ac.idArif Rahman Azisarifrahmanaziz@unib.ac.idMuhammad danimdani@unib.ac.idTeguh Rafianteguh.rafian@fp.unila.ac.idDhini Nova Widyasaridhininova47@gmail.comNurazizah Ramadhantinramadhanti@unib.ac.idRizky Amrullah Chaniagorachaniago@unib.ac.idAnggun Marisaanggunmarisa@unib.ac.idVirna Maharani Dwipassavirnamaharanidwipassa@unib.ac.id<p>Broodiness is a natural reproductive behavior that plays a vital role in the success of hatching and maternal care in indigenous chickens. This behavior is governed by a complex interaction between endocrine and genetic factors, with the prolactin (PRL) gene serving as a key regulator. The prolactin hormone encoded by the PRL gene stimulates broody behavior, temporarily suppresses egg production, and enhances the maternal instinct to remain on the nest. Genetic variation in the PRL gene polymorphism is associated with the differences in the intensity and frequency of brooding behavior between chicken breeds and local populations. Specific alleles of the PRL gene are associated with increased broodiness, while others are linked to reduced expression and weakened maternal behavior. Studies on Indonesian local chickens demonstrate a significant upregulation of PRL expression during the brooding phase, confirming its central role in the regulation of reproductive behavior. These findings suggest that the PRL gene holds strong potential as a molecular marker in genetic selection programs. Through marker-assisted selection, breeders can maintain strong broody traits for natural hatching or suppress them to enhance egg productivity. Therefore, a deeper understanding of the structure, function, and genetic variability of the PRL gene provides a crucial foundation for developing adaptive, efficient, and sustainable breeding programs for indigenous chickens.</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Woki Bilyaro, Arif Rahman Azis, Muhammad dani, Teguh Rafian, Dhini Nova Widyasari, Nurazizah Ramadhanti, Rizky Amrullah Chaniago, Anggun Marisa, Virna Maharani Dwipassahttps://ejournal.unib.ac.id/buletin_pt/article/view/45663The Penggunaan Bungkil Inti Sawit dan Bungkil Kedelai Sebagai Sumber Protein dalam Pakan Konsentrat Kubus pada Kambing Kacang2025-11-05T00:31:26+00:00Hidayat Hidayathidayat@unib.ac.idTris Akbarillahtrisakbarillah.61@gmail.comIrma Badarinairmabadarina@unib.ac.id<p>This experiment aimed to compare palm kernel meal and soybean meal as sources of rumen undegradable protein for kacang goats. Sixteen 10-month-old doeling weighing between 13-14 kg were used as experimental animals. A completely randomized design was applied to test four types of feed treatments, namely setaria grass-based feed and different cube-shaped concentrate feed (CCF), with four replications for each treatment. The four types of treatments were: P1. CCF without soybean meal, P2. CCF with soybean meal without heating, P3. CFF with soybean meal heated at 165<sup>o</sup>C for 75 minutes, and P4. CCF with soybean meal heated at 165 <sup>o</sup>C for 150 minutes. Each treatment was given a ration consisting of 50% Setaria grass as a basal feed and 50% CCF according to the treatment (on a dry matter basis). The variables observed were dry matter and nutrient intake, dry matter and nutrient digestibility, and average daily weight gain for 12 weeks. The data obtained were analyzed using analysis of variance (ANOVA) using the Systat for Windows statistical software package, if there were differences, further testing was carried out using the least significant difference (LSD) test. The results showed that nutrient intake was not significantly different (P>0.05), but the lowest digestibility value (P<0.05) was in treatment 4, CCF which used soybean meal with longer heating. The highest daily weight gain (P<0.05) was achieved by goats that received PKK palm kernel meal. It was concluded that the use of palm kernel cake in CCF gave good results, as indicated by the highest average daily gain of goat</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Hidayat Hidayat, Tris Akbarillah, Irma Badarinahttps://ejournal.unib.ac.id/buletin_pt/article/view/45672Karakteristik Morfometri Testis dan Tingkat Motilitas Sperma Kucing Berdasarkan Variasi Umur di Kota Pekanbaru, Indonesia2025-11-05T00:40:49+00:00Frilianty Putrifriliantyputri@lecturer.unri.ac.idTito Suprayogatito.suprayoga@lecturer.unri.ac.idHadimas Bakti Pratamafriliantyputri@lecturer.unri.ac.idRifia Tiara Fanifriliantyputri@lecturer.unri.ac.idMulya Fitrandafriliantyputri@lecturer.unri.ac.idTriawan Alkausarfriliantyputri@lecturer.unri.ac.idWiwin Suhandrifriliantyputri@lecturer.unri.ac.idIndra Jayafriliantyputri@lecturer.unri.ac.idAnggrek Citadika Ratu Radjafriliantyputri@lecturer.unri.ac.idDebita Zakiahfriliantyputri@lecturer.unri.ac.id<p style="font-weight: 400;">This study aimed to analyze the effect of age variation on testicular morphometry and spermatozoa motility in cats. A total of 21 male cats were grouped into three age categories (< 1 year, 1–3 years, and 3 years). The testes were collected through an open castration procedure, and their morphometric parameters (length, width, and circumference) were measured. Semen samples were obtained by incising the <em>cauda epididymis</em> of each testis to evaluate its motility level under a light microscope. Data were analyzed using one-way <em>Analysis of Variance</em> (ANOVA), followed by the Tukey test to identify differences between groups. The results showed that age variation did not cause a significant difference in the morphometric characteristics of the collected testes (P>0.05). However, a significant difference was found in spermatozoa motility levels among the different age groups. It is concluded that age does not affect the physical dimensions of the testis but has a significant influence on the functional quality of spermatozoa. The 1–3 year-old group showed the optimal level of spermatozoa motility compared to the other age groups in this study</p>2025-11-25T00:00:00+00:00Copyright (c) 2025 Frilianty Putri, Tito Suprayoga, Hadimas Bakti Pratama, Rifia Tiara Fani, Mulya Fitranda, Triawan Alkausar, Wiwin Suhandri, Indra Jaya, Anggrek Citadika Ratu Radja, Debita Zakiah
