5.0 MANUFACTURED FEEDS FOR AQUACULTURE
The world’s feed manufacturing industry, which has its origins in the western industrialized countries, arose from the need to supply large quantities of meat products for urban consumption. The industry initially provided simple services to farmers such as grinding of coarse grains and blending fodders in the proportions dictated more by available supplies than by needed balance of nutrients in the final mixtures. As the demand for animal products increased, new methods for their production became necessary. It soon became apparent that such production could only be achieved by adoption of intensive animal husbandry, whereby traditional feeding methods had to be replaced by more efficient ones based on new knowledge concerning the nutritional requirements of farm animals for growth and production. This new knowledge, together with the discovery that farm animals responded well to diets containing a wide variety of food grains and agricultural by-products, provided basic dietary nut See full list on fao.org It is widely recognized in the feed manufacturing industry that steam conditioning is of vital importance in pelleted feed production. The use of steam Under normal operating conditions involving a single horizontal barrel-type steam conditioner, mash transit time is brief – between 5 and 20 seconds. During this short period, liquids such as molasses or fats that are added may not be absorbed sufficiently to prevent their interference with the subsequent pelleting process. Excess water (from added molasses) may “choke” up the die causing interruption in pellet production. Excess unabsorbed fat results in production of soft pellets with low durability. To overcome these effects, recent developments have centred on providing greater retention time of feed that include high levels of added liquids in the conditioner. Two new processes have been proposed (Carmichael, R.Q., 1981). One describes a long term conditioning process involving retention of feeds in a ripening kettle. The other,… See full list on fao.org Feed cost represents 40 to 60 percent of total operating cost in intensive aqua-culture. For a fish farm to be profitable, feed cost should not exceed 20 percent of the farm-gate value of the product if the feed used is the dry type, and not more than 10 percent if moist type pellets are employed. Typically, a ton of dry pelleted feed, based on conventional ingredients, in a developing country that relies upon imports for most of its supplies of feed protein supplements ranges from US$ 300 to US$ 400, depending upon its protein content. To this must be added: The cost to the farmer, then, ranges from US$ 320 for a ton of 27 percent protein feed for tilapia and carp to US$ 425 for one that contains 40 percent protein for trout. At these prices, the farmer breaks even if tilapia and carp fetch US$ 1.60/kg and trout US$ 2.13, at the farm gate 1/. Current prices for these fishes, especially for trout, in most countries are considerably higher, indicating the feasibility of employing ind… See full list on fao.org
