Abstract
Description
technical field
[0001] The invention belongs to a compound feed for oval pomfret. Background technique
[0002] The pomfret (Trachinotus ovatus) has tender meat and delicious taste. The fish grows fast and has strong anti-stress ability. It is easy to breed in seawater cages and has good promotion and application value. One of the cultivated species. There are few studies on the nutritional requirements and feed of Pompano ovata, and there is no special feed. Domestic breeding mainly uses natural fresh bait such as chilled small miscellaneous fish and shrimp. However, the source of natural chilled bait is unstable, easily affected by typhoon season and other factors, and the cost is high, storage is difficult, water quality is easy to deteriorate, and the fish body has a high incidence rate. So far, the basic framework of nutritional parameters of pomfret ovata has not been constructed. Contents of the invention
[0003] The purpose of the present invention is to provid...
Examples
Embodiment 1
[0007] First weigh 36 kg of high-quality steamed fish meal, 15 kg of puffed soybean meal, 9 kg of peanut meal, 5 kg of meat meal, 5 kg of squid offal powder, 4 kg of beer yeast, 19 kg of flour, 0.4 kg of multivitamin, and 0.6 kg of compound mineral salt. These solid feeds were crushed through an 80-mesh sieve, mixed, and then mixed with 1.0 kg of soybean lecithin, 2.5 kg of marine fish oil, and 2.5 kg of soybean oil. Press pellets to produce extruded feed with a particle size of 2.0-8.0mm. The compound vitamins and compound mineral salts used in this compound feed refer to the formula of Rodehutscord et al. (1996) (Journal Nutrition, 126 (1996): 324-331). Experiments have proved that the compound feed of the present invention can meet the nutritional needs of pomfret, promote the rapid growth of pompano, improve its digestion and absorption rate of feed, reduce nitrogen and phosphorus excretion, feed coefficient 1.2 to 1.5, and aquaculture survival rate Reach more than 80%.
