<p><strong>English</strong><br />The beef self-sufficiency program is aimed at raising beef cattle population to meet national meat consumption. If the program is successful it will reduce imports of live cattle, feeder cattle and beef. Sustainability of this program is expected to achieve beef self-sufficiency in the future. Self-sufficiency is ability to meet domestic demand with beef import of not more than 10 percent which is not produced domestically.  Business of beef cattle breeding today is mostly conducted by small-scale farmers with cow-calf operation pattern usually integrated with other agricultural commodity farms. To increase supply of of feeder cattle and population of beef cattle population at national level it requires certain efforts. In order to enhance cattle breeding business from small-scale to medium-scale ones, some efforts are needed such as integration pattern between crops and cattle. Opportunities for integrating crops and beef cattle are promising. The farmers need to apply technologies to access cheaper feed.  Credit provision with low interest rate and less complicated procedure to the bank for animal procurement will help farmers in increasing their livestock farm scales. Assistance of extension workers and related livestock officers are critically important to farmers in dealing with their beef cattle breeding business.</p><p> </p><p><strong>Indonesian</strong><br />Program swasembada daging sapi (PSDS) pada dasarnya merupakan kegiatan yang diarahkan untuk meningkatkan populasi sapi potong. Program tersebut diarahkan agar kebutuhan konsumsi daging secara nasional dapat terpenuhi. Keberhasilan program tersebut berimplikasi pada menurunnya prosentase impor baik sapi hidup terutama sapi bakalan maupun daging sapi. Kekurangan daging sapi secara nasional selama ini masih ditanggulangi melalui impor daging maupun sapi hidup yang nilainya cukup besar. Keberlanjutan program ini dimaksudkan agar dimasa mendatang secara perlahan diharapkan Indonesia dapat mencapai swasembada. Pengertian swasembada yang dimaksud adalah besarnya kebutuhan daging asal impor tidak lebih dari 10 persen. Besaran daging impor 10 persen tersebut merupakan daging yang memang belum dapat diproduksi di dalam negeri. Dilihat dari pelaku usaha pembibitan sapi potong saat ini, sebagian besar diusahakan  dan dikembangkan oleh usaha peternakan rakyat dengan pola produksi induk-anak (cow-calf operation) dalam usaha skala kecil dan biasanya terintegrasi dengan usaha pertanian lainnya. Untuk meningkatkan ketersediaan jumlah bibit sapi bakalan secara nasional dan dalam  upaya peningkatan populasi sapi potong diperlukan upaya–upaya tertentu. Agar usaha pembibitan ternak sapi potong dapat berkembang dari skala kecil menjadi skala menengah salah satu upaya adalah peningkatan skala usaha yang dapat diimplementasikan melalui pola integrasi antara tanaman dengan ternak sapi potong. Peluang untuk pengembangan kearah tersebut sebenarnya terbuka lebar, hanya saja diperlukan upaya serius untuk menindaklanjuti usaha tersebut. Untuk mengarah dari usaha pembibitan tradisional skala kecil ke usaha pembibitan skala menengah memang tidak mudah, banyak hal yang harus diupayakan dan diperlukan penanganan yang lebih serius oleh pemerintah terutama dalam hal peningkatan aplikasi teknologi ke peternak terutama teknologi pengadaan pakan murah dan mudah yang bisa dijangkau oleh peternak. Selain itu kebijakan penyediaan plafon kredit untuk pengadaan ternak dengan bunga rendah yang mudah diakses dengan aturan yang lebih fleksibel sangat membantu peternak dalam meningkatkan skala usaha pembibitan ternak sapi potong. Untuk semua itu, peran penyuluh maupun dinas peternakan dalam membantu peternak untuk mengatasi permasalahan dilapangan sangat dibutuhkan.</p>

<p>Siwab or its extension Mandatory cattle breeding is a manifestation of government commitment in increasing beef cattle population, and as a target for meat sufficiency in 2026. The program is believed to lead Indonesia to achieve beef self-sufficiency in the next 5-10 years. Beef cattle can be maximized in order to produce calves, and become a government’s focused program on enhancing beef cattle production through artificial insemination (AI). Based on the above problems, the government hopes to develop the program, it should not fail the umpteenth time to fulfil meat needs of the country. The purpose of this review is to describe the SIWAB program and the economic value of female beef cattle produced by AI which produces calf. This study approach is done through literature reviews related to SIWAB program implementation. SIWAB program includes two main programs namely the increase of porong cattle population through artificial insemination of AI and natural mating (Inka). With the AI through prgram, the parent beef cattle can regulate the cow's birth well. The mother cow bunting AI results can increase the selling value higher and can improve the welfare of farmers. The government's policy to pursue targeted beef self-sufficiency by the year 2026 is achieved, but the program must be responded and done well. Government policy to boost short-term beef cattle population can help to meet the needs of beef consumption, and in the long run the economic impact of farmers.</p><p> </p><p>Abstrak</p><p>Program Sapi Induk Wajib Bunting (SIWAB) adalah perwujudan komitmen pemerintah dalam meningkatkan populasi sapi potong dan sebagai target untuk kecukupan daging tahun 2026. Program tersebut diyakini dapat mengantarkan Indonesia mencapai swasembada daging sapi pada 5-10 tahun ke depan. Sapi potong dapat dimaksimalkan potensinya agar dapat menghasilkan pedet, dan menjadi program pemerintah yang difokuskan untuk peningkatan produksi sapi potong melalui inseminasi buatan (IB). Berdasarkan permasalahan tersebut di atas, harapan pemerintah dengan mengembangkan program tersebut tidak boleh gagal ke sekian kalinya dalam mencukupi kebutuhan daging di dalam negeri. Tujuan tulisan review ini adalah untuk  mendiskripsikan program SIWAB dan nilai ekonomi pada usaha sapi potong betina hasil IB yang menghasilkan pedet. Kajian ini merupakan studi pustaka melalui review berbagai referensi terkait pelaksanaan program SIWAB. Program SIWAB mencakup dua program utama yaitu peningkatan populasi sapi porong melalui inseminasi buatan IB dan kawin alam (Inka). Program IB memungkinkan mengatur kelahiran anak sapi dengan baik. Sapi induk bunting hasil IB dapat meningkatkan nilai jual lebih tinggi dan dapat meningkatkan kesejahteraan peternak. Kebijakan pemerintah adalah untuk mengejar swasembada daging sapi yang ditargetkan sampai tahun 2026 bisa tercapai, namun program tersebut harus direspon dan dikerjakan dengan baik. Kebijakan pemerintah untuk menigkatkan populasi sapi potong dalam jangka pendek bisa membantu memenuhi kebutuhan konsumsi daging sapi dan dalam jangka panjang berdampak peningkatan ekonomi peternak.</p>

The increase in beef production is constrained by the slow growth of beef cattle population which is caused by the cattle breeding business that is considered less commercially profitable. The supplying of beef needs in a critical and effective manner is always increasing each year, so the price of beef is fluctuate. The various priority concept of the government's main program for the development of beef cattle is always done in every region in Indonesia. But the production of beef is still less and the government have to import the beef to fulfill the beef production. Therefore, this issues need necessary operational steps to provide more open space for some factors and leverage points in the supplying of beef needs. The purpose of this review is to examine the efforts to supply beef needs for the future in Indonesia critically. The high price of beef is not a mistake of the government. Basically, the government has tried to make the beef cattle population increased, to fulfill the consumer needs and the prices of beef is affordable for the customer. To cope with the higher beef prices, the government is make a policy of developing small, medium-sized, and big beef cattle breeding industries through seed cattle spreads on plantations of oil palm, rubber and cultivable fields for the development of beef cattle population. It is expected that in the coming year, beef cattle business can be oriented to agribusiness bussiness so that farmer's welfare will increase and can support Indonesia as the world food granary.

Abstract Increasing food production can be done through increasing productivity and increasing business scale, both of them need an additional cost. Meanwhile, capital for small-scale farmers is relatively limited, so financial support is needed. At present, the Government financing support in the form of loans program is the People’s Business Credit (KUR). The objective of the study is to analyze the role of KUR in beef cattle business and the effect on increasing livestock production. The research was conducted in 2020 in Central Lampung District with a survey method of 60 farmer respondents. The study revealed that at the national level, the participation rate of beef cattle farmers in the use of KUR was only 2.71%, and in Lampung Province, it reached 7.72%. Beef cattle farmers in the study locations used KUR funds for on-farm farming. Most of the farmers (84.4%) used the funds to purchase brood stock. The KUR program has an impact on increasing the productivity of cattle for fattening 0.2 kg live weight/head/day, increasing the scale of cattle breeding, and fattening two cows and eight cows respectively per farmer. The impact of KUR on enhancing production due to increased productivity and business scale is significantly determined by the level of farmer participation in the use of KUR. It is needed to increase farmer participation in the use of KUR and the use of KUR funds to adopt recommended technology. So that, KUR has impact on increasing livestock production.

The objective of this study was to investigate the feasibility and reasonable production costs for small cattle farmers in Nakhon Sawan Province of Thailand. Small-scale beef cattle are naturally reared by farmers without planning. Studying the primary data of beef cattle farming models and comparing the economic return costs of each form of beef cattle farming among smallholder farmers in Nakhon Sawan Province of Thailand shows that the yields are not worthwhile. By applying the specific method to 25% of the area of all farms in Nakhon Sawan Province and comparing the descriptive statistical yields, the results showed that two types of cattle with 4 characteristics predominate. The first is rearing pregnant mother cows for sale and buying mother cows. The second category is feeder cattle, release cattle and fattening cattle. A study of the costs and economic compensation of suitable small-scale beef cattle farmers in Nakhon Sawan Province of Thailand found that cattle farms should raise cattle because the yield from farming is valued and because of the economic returns and the time spent. The payback for this form is faster than other forms of investment.

<p>Se presentan los resultados de aplicar una metodología rápida y económica para tipificar sistemas de producción bovinos a partir de datos obtenidos de fuentes secundarias. La metodología describe modelos estructurales de producción ganadera y los ubica espacialmente determinando sistemas modales. Para ello se utilizan estadísticas básicas del departamento de Santander (Colombia), que asumen el municipio como unidad de análisis. Se proponen y usan algunas variables para el desarrollo y cálculo de indicadores relacionados con aspectos estructurales de los sistemas de producción, tales como la ocupación y uso de la superficie agropecuaria, la estructura demográfica bovina, el tamaño predial de las fincas, la distribución rural y urbana de la población humana, la vacunación contra la fiebre aftosa y la utilización de pastos mejorados. Mediante técnicas estadísticas de Análisis Multivariado, Correlación Múltiple, Análisis de Componentes Principales y Análisis Jerárquico de Conglomerados fue posible identificar tipologías, calculando matemáticamente sus descriptores. Así, se identifican y describen cuatro tipologías estructurales: bovinos de cría en el modelo de economía campesina, bovinos para producción de carne, bovinos como actividad complementaria de la economía campesina agrícola y bovinos de cría y levante en un modelo pre-empresarial. La ubicación espacial de las tipologías se realizó dentro de subregiones naturales (Zona Fría, Montaña Santandereana, Hoyas de los Ríos Ponce Chica mocha y Suárez y Valle del Magdalena Medio), lo cual condujo a la identificación de doce subgrupos que se priorizaron de acuerdo con su inventario ganadero para una mejor descripción de las tipologías.</p><p> </p><p><strong>Methodological approach for classification of cattle production systems from secondary information sources</strong></p><p>A rapid and low cost methodology was applied to classify cattle production systems using data from secondary sources. This methodology identifies, describes and specially locates modal cattle production systems. Basic information on biophysical and socioeconomical aspects of the department of Santander (Colombia) was used for this purpose, considering the municipality as the unit of analysis. A set of variables was used to calculate structural indicators of the production systems such as: land use in agriculture, structure of the bovine population, farm size, use of improved pastures, foot and mouth disease vaccination records, as well as rural and urban human populations. In order to define and calculate the descriptors for classification of these systems multivariate analysis, multiple correlation, principal components and cluster analysis were applied. Four system s were identified and described: (1) cow-calf owned by small farmers, (2) beef cattle production enterprises, (3) small operations of cow-calf and feeder cattle, and (4) bovines as complement to crop production in small farms. A methodology was developed to locate the above systems under the natural subregions: Cold zones, Santander highlands, Fonce Chicamocha and Suárez basin rivers and Medium Magdalena Valley; thus leading to the identification of 12 subgroups, which were prioritized according to their cattle populations, and as a result provide adequate means to describe beef cattle production systems.</p>
