Apparent digestibility of selected feed ingredients in diets for grouper (Epinephelus coioides) juveniles
MetadataShow full item record
This study was conducted to determine the quality of selected feed ingredients as protein sources in grouper diets, based on their nutrient composition and apparent digestibility coefficients for dry matter (ADMD) and crude protein (APD). A total of 56 juveniles were used for the 1st batch of test ingredients (Chilean fish meal, white fish meal, shrimp meal, defatted soyabean oilmeal, white cowpea meal and ipil-ipil leaf meal). 54, 72 and 48 juveniles were used for the 2nd, 3rd and 4th batches of test ingredients (squid meal, local meat and bone meal, meat solubles, soya protein concentrates and rice bran; tuna fish meal, imported meat and bone meal, blood meal, maize gluten meal and wheat flour; and poultry feather meal, lupin seed meal and maize germ meal, respectively). Apparent digestibility coefficients were measured in vivo. The apparent digestibility coefficients for ADMD ranged from 37-99%. Squid meal and meat solubles had the highest coefficients, whereas blood meal had the lowest. The APD of all feed ingredients tested were relatively high (79-99%), except for rice bran (43%) and blood meal (15%). ADMD values varied with the levels of fibre and other carbohydrate substances in the feed ingredients. Groupers could utilize dietary protein efficiently regardless of whether it was of animal or plant origin. High APD values were generally obtained in feed ingredients with high protein content. Low digestibility coefficients for feed ingredients could also be attributed to the processing methods used in their preparation.

Book chapterVR Alava - In OM Millamena, RM Coloso & FP Pascual (Eds.), Nutrition in Tropical Aquaculture: Essentials of fish nutrition, feeds, and feeding of tropical aquatic species, 2002 - Aquaculture Department, Southeast Asian Fisheries Development CenterThis chapter teaches the reader to: differentiate the different feeding strategies in pond culture; learn feeding management methods such as stock sampling and record keeping, calculating daily feed ration, choosing appropriate feed size, and methods of applying feeds; understand the impact of feeding management on water quality and environment and on the cultured animal’s growth, survival, and feed conversion ratio; and describe the different feeding schemes used to culture fishes (milkfish, tilapia, rabbitfish, bighead carp, native catfish, sea bass, orange-spotted grouper, and mangrove red snapper; and crustaceans (tiger shrimp and mud crab). Other species for aquaculture stock enhancement (donkey’s ear abalone, seahorses, window-pane oyster) are also discussed.
Book chapterNV Golez - In OM Millamena, RM Coloso & FP Pascual (Eds.), Nutrition in Tropical Aquaculture: Essentials of fish nutrition, feeds, and feeding of tropical aquatic species, 2002 - Aquaculture Department, Southeast Asian Fisheries Development CenterThis chapter will help the reader understand and appreciate the basic principles of processing, preparation, storage, and quality control in the preparation of aquafeeds. The material in this section is presented in sequence beginning with the processing of basic ingredients to remove antinutritional factors, followed by steps in feed preparation, from the easiest to the more complex processes, and storage. This chapter presents methods and equipment that are useful not only for feed millers, but also for extension workers and fish farmers.

Development and use of alternative ingredients or fish meal substitutes in aquaculture feed formulation: Proceedings of the ASEAN Regional Technical Consultation on Development and Use of Alternative Dietary Ingredients or Fish Meal Substitutes in Aquaculture Feed Formulation MR Catacutan, RM Coloso & BO Acosta (Eds.) - 2015 - Aquaculture Department, Southeast Asian Fisheries Development CenterRecognizing the need for a concerted effort to follow-up on this priority issue of the ASEAN on aquaculture feed development and utilization. SEAFDEC (Aquaculture Department and Secretariat) and the Government of Myanmar organized the 'Regional Technical Consultation (RTC) on development and Use of Alternative Dietary Ingredients or Fish Meal Substitutes in Aquaculture Feed Formulation'. The meeting was convened with the main purpose of providing a forum for charting the regional priorities and future directions on feed development, particularly on the use of alternative feed ingredients or protein substitutes. The specific objectives were to: (i) review the ASEAN-SEAFDEC member country status, constraints associated with developing alternative dietary ingredients for aquaculture feed; (ii) identify specific advances being made in the region with respect to the development of alternative aquaculture feed ingredients; and (iii) define approaches or initiatives supporting catch reduction of low-value/trash fish; (iv) formulate relevant policy recommendations (regional and country-specific) for effective development and utilization of aquaculture feeds; and (v) enhance cooperation among member countries and relevant stakeholders on initiatives that support sustainable aquaculture practices, particularly on feeds. This publication presents the outputs of the RTC. The country reports and review papers presented during the conference which are contained in this volume are cited individually.
