The purpose of this study was to analyze the prospects and determine the development of beef cattle in Kolaka Regency. This study was centered in Watubangga District because it is the base area for beef cattle development. The research variables include the social characteristics of farmers and production costs, involving 45 farmers as respondents. The data analysis method used in this research is the Revenue-Cost approach and the Cobb-Douglas production function using the natural logarithm model. The research results show that the beef cattle business in Kolaka Regency has prospects or is profitable for development with an R/C ratio of 3,12. Meanwhile, the variables of total production and investment costs determine the prospects for developing beef cattle farming in Kolaka Regency. Therefore, support from across sectors is needed to improve the beef cattle business in the future, especially in terms of accessibility of business funding sources.</p> Rina Astarika La Ode Jabuddin Abdi Abdi Deki Zulkarnain La Ode Muhammad Munadi Copyright (c) 2024 ANIMAL PRODUCTION https://creativecommons.org/licenses/by-sa/4.0 2024-08-28 2024-08-28 138 149 10.20884/1.jap.2024.26.3.305 https://jap.fapet.unsoed.ac.id/index.php/JAP/article/view/307 <p class="p1">The meta-analysis in this study was conducted to determine the protein and energy requirements of various cattle breeds in Indonesia. A database was compiled from various research articles that involved cattle as the experimental animals, focusing on studies that reported energy and protein intake, initial body weight, and average daily gain (ADG). In total, 57 articles covering different cattle breeds in Indonesia, with 191 data points, were integrated into the database. The database specified different breeds (Aceh, Bali, Madura, Peranakan Ongole (PO), Sumba Ongole (SO), and Local) and sexes. Regressing ADG used to determine maintenance and gain requirements of dry matter, energy, and protein with dry matter intake (DMI), total digestible nutrient intake (TDNI), and crude protein intake (CPI), respectively. An intercept (where ADG= 0 kg/kg MBW/d) and a slope (required nutrient intake per unit ADG) were taken as maintenance and gain requirements, respectively. Results revealed that protein and energy requirement for maintenance (CPm and TDNm) of all cattle breeds varied in values, ranging from 0.0014 to 0.0102 kg/kg MBW/d (Madura and PO breeds) and 0.0232 to 0.0687 kg/kg MBW/d (Aceh and PO breeds), respectively. Each cattle breed in Indonesia has its particular CP and TDN requirements. Both energy and protein requirements for maintenance (CPm and TDNm) and gain (CPg and TDNg) varied in value for each breed.</p> Samadi Samadi Sitti Wajizah Andika Boy Yuliansyah Ilham Anuraga Jayanegara Copyright (c) 2024 ANIMAL PRODUCTION https://creativecommons.org/licenses/by-sa/4.0 2024-09-11 2024-09-11 150 162 10.20884/1.jap.2024.26.3.307
