Feed efficiency in the growth of humpback grouper Cromileptes altivelis with prebiotics dietary modulation

Abstract

Energy for fish to carry on with its biological activities and growth comes from food that they eat. In artificial diets, protein become the most expensive source of energy so it is necessary to keep the proportion of protein down to the optimum levels for good growth and feed conversion. In another study, prebiotics resulted in good growth of fish using a manufactured prebiotic supplement. Ideally, we want food material available all year, inexpensive and not be in competition with food material for human consumption. In this study, food formulation with prebiotics made from local products were prepared for fish food. In this study sago was the source of carbohydrates, mackerel and land snails were the source of protein. The formulation was fed to humpback grouper Cromileptes altivelis to study the effectiveness on its growth. Ninety humpback groupers (size 9-9.5 cm, weight 10 – 11 g) were reared in 3 fiberglass tanks for four weeks. Each tank had 30 fish, first tank as control without sago and the two tanks with sago in dietary prebiotic pellet. Length and weight gain were recorded every week then growth performance of fish were assessed in the form of Specific Growth Rate (SGR), Food Conversion Ratio (FCR), weight gain daily and length-weight relationship. Food proximate test were carried out separately in the Integrated Chemistry Laboratory, Institut Pertanian Bogor. Data analysis showed a significant difference in the growth performance of humpback grouper through the values of SGR, FCR and average growth daily, between treatment A and B (with sago) and treatment C (control, zero sago). The proximate test displayed lower protein in treatment A (57.95%) and B (55.95%) but higher in treatment C (59.37%), in the contrary to carbohydrate for treatment A (27.80%), treatment B (26%) and treatment C (22.98%).

Partial replacement of fish meal by soybean meal supplemented with inulin and oligofructose in the diet of pikeperch (Sander lucioperca): Effect on growth and health status

“…Prebiotics are non-digestible carbohydrates that are used as dietary supplements to mitigate the effects of various antinutritional factors and reduce the adverse effects of replacement diets, such as diets formulated with SM (Li and Gatlin, 2004;Li and Gatlin, 2005;Burr et al, 2008). In addition, they positively affect innate immune responses via modification of the gastrointestinal microbial community (Loṕez Nadal et al, 2020), improve oxidative status by reducing oxidative damage or increasing antioxidant potential (Zhang et al, 2013;Zhang et al, 2014;Guerreiro et al, 2015), increase mineral absorption (Bongers and van den Heuvel, 2003), and improve growth rate and feed conversion (Pattipeiluhu et al, 2020).…”

“…Pemberian pakan berhubungan dengan kualitasnya yang bervariasi, semakin baik kualitas pakan semakin cepat pertumbuhannya. Kualitas prima pakan seperti pemberian pakan prebiotic untuk mendapatkan pertumbuhan yang optimum, akan sangat menguntungkan karena biasanya lebih dari 50% biaya produksi pada budidaya intensif berhubungan dengan biaya pakan (Pattipeiluhu et al, 2020).…”

Prebiotik dan Dermatitis Atopik pada Anak

“…Prebiotik adalah bahan yang tidak dapat dicerna yang secara menguntungkan mempengaruhi tubuh dengan merangsang pertumbuhan secara selektif atau membatasi beberapa spesies bakteri usus, seperti Bifidobacterium dan Lactobacilli yang berpotensi meningkatkan kesehatan inang (Pattipeiluhu et al, 2020). Probiotik adalah mikroorganisme hidup yang memberikan manfaat kesehatan pada inangnya jika diberikan dalam jumlah yang cukup (Swanson et al, 2020).…”
