“…The cost of liveweight gain in the Intervention group was lower than that previously reported by Cruz de Carvalho et al (2010) for Simmental-Ongole crossbred cattle fed a 55% concentrate diet in a feedlot system (IDR 16947/kg), most likely because of the collection of forages free of charge. However, because of the substantial differences between the two treatments in ADG and the period of time to reach a specified weight, using cost of gain as an indicator of profitability is insufficient (Allison & Baird 1974). Income over feed cost instead considers the total value of liveweight increased in the fattening period: where gross returns per day are sufficiently high, these can more than compensate for the increased cost of gain.…”

ABSTRAKRatnawati D, Cowley F, Mayberry D, Pamungkas D, Poppi D. 2015. Penambahan konsentrat pada ransum sapi jantan persilangan untuk meningkatkan keuntungan peternak sapi penggemukkan di Jawa Timur, Indonesia. JITV 20(1): 42-48. DOI: http://dx.doi.org/10. 14334/jitv.v20i1.1115 Tingkat pertumbuhan sapi pada system penggemukkan oleh peternak skala kecil secara umum masih rendah karena kebutuhan nutrisi kurang tercukupi. Penelitian ini bertujuan untuk membandingkan pertumbuhan sapi dan keuntungan peternak antara sapi jantan dengan pakan tradisional dan sapi jantan dengan pakan tambahan (suplemen) berupa konsentrat berkualitas tinggi. Penelitian ini dilakukan di dua lokasi di Jawa Timur yaitu Probolinggo dan Lamongan dengan menggunakan sapi jantan persilangan PO-Bos taurus berumur 1,5-2 tahun dari yang dibedakan menjadi 2 kelompok perlakuan, yaitu kelompok kontrol dan intervensi. Peternak pada kelompok intervensi, sapi jantan diberi pakan suplemen berupa campuran: onggok, kopra dan bungkil inti sawit. Peternak memberikan suplemen sebanyak 4 kg/ekor selama 161 hari atau sampai terjual. Managemen pakan pada kelompok kontrol adalah tetap (pola peternak). Umumnya peternak menggunakan hijauan lokal dan hasil samping pertanian sebagai pakan ternak, tanpa adanya suplementasi. Biaya pakan harian dan harga per 1 kg pertambahan bobot badan sapi lebih tinggi pada kelompok intervensi (Rp. 8.827 dan Rp. 11.990) daripada kelompok kontrol (Rp. 2.606 dan Rp. 5.543). Namun demikian, pertambahan bobot badan harian sapi jantan kelompok intervensi (0,82 kg/hari) lebih tinggi dibandingkan dengan kelompok kontrol (0,52 kg/hari), sehingga menghasilkan keuntungan yang lebih besar. Pendapatan harian dikurangi dengan biaya pakan pada peternak kelompok intervensi (Rp. 24.182/hari) lebih tinggi dibandingkan dengan kelompok kontrol (Rp. 5.774/hari). Dapat disimpulkan bahwa meskipun terdapat biaya tambahan untuk memberikan pakan berkualitas tinggi, namun dengan tingkat pertumbuhan sapi jantan yang tinggi menghasilkan keuntungan lebih besar pada peternak.

DOI: http://dx.doi.org/10.14334/jitv.v20i1.1115Growth rates of bulls in Indonesia raised in smallholder fattening systems are generally low due to inadequate nutrition. This study compared bull growth and farmer profit between two feeding management systems, namely traditional feeding (as control) and intervention feeding by supplementation with a high quality concentrate. Bos taurus-Ongole cross bred bulls (n=46) aged 1.5-2 years, owned by smallholder farmers, from two villages in East Java were used in this study. The bulls were divided into two treatment groups; control and intervention. Farmers in the intervention group were provided with a concentrate containing onggok, copra and palm kernel cake. Farmers were instructed to feed 4 kg DM of concentrate/bull/day in add...

“…Least-cost rations minimize the cost of diets, given a certain set of ingredients and their nutritional content. An important assumption of least-cost formulated diets is that every unit of a least-cost formulated ration has the same productivity regardless of ingredient sources (Allison and Baird, 1974).…”

Increased emphasis on consumer markets in broiler profit-maximizing modeling generates results that differ from those by traditional profit-maximization models. This approach reveals that the adoption of step pricing and consideration of marketing options (examples of responsiveness to consumers) affect the optimal feed formulation levels and types of broiler production to generate maximum profitability. The adoption of step pricing attests that higher profits can be obtained for targeted weights only if premium prices for broiler products are contracted.
Um aumento na ênfase dada ao mercado de consumidores de carne de frango e modelos de maximização de lucros na produção de frangos de corte geram resultados que diferem daqueles obtidos em modelos tradicionais de maximização de lucros. Esta metodologia revela que a adoção de step-pricing e considerando opções de mercado (exemplos de resposta às preferências de consumidores) afetam os níveis ótimos de formulação de rações e os tipos de produção de frangos de corte que geram uma lucratividade máxima. A adoção de step-pricing atesta que maiores lucros podem ser obtidos para pesos-alvo somente se preços-prêmio para produtos processados de carne de frango forem contratados

Least cost feed mix by linear programming (LP) is a standard economic analysis in the poultry industry. A significant body of nutrition knowledge is now contained in the constraint set of industry LP models. This knowledge might be merged into an improved economic model that contains production response information. Analysis using a quadratic programming model indicated that a leading broiler firm could have improved economic efficiency by increasing protein density and reducing energy density of broiler finisher feed. If applicable industry wide, similar savings could be as high as $120 million per year.
