Embodiment 1

[0018] Embodiment one: by formula 1 preparation feed shown in table 1, raising 3.7g yellowfin bream juveniles 60 days, feed coefficient 1.4, specific growth rate (SGR, % / day) 2.65, survival rate 98%, and throw something to feed algae Compared with , shellfish and fresh miscellaneous fish, etc., the specific growth rate increased by 45%, the feed factor decreased by 30%, the survival rate increased by 36%, and the apparent digestibility of phosphorus increased by 35%.

Embodiment 2

[0019] Embodiment two: formulate feed by formula 2 shown in table 1, raise 9.8g juvenile yellowfin seabream for 60 days, feed coefficient 1.32, specific growth rate 2.22, survival rate 95%, ammonia nitrogen discharge is 22mg kg -1 h -1 , the apparent digestibility of phosphorus is 75%, compared with the general salty water fish compound feed on the market, the specific growth rate is increased by 40%, the feed coefficient is reduced by 30%, the survival rate is increased by 27%, and the apparent digestion of phosphorus The efficiency has been increased by 21%, and the ammonia nitrogen emission is 30% lower than that of the common brackish water fish compound feed on the market.

Embodiment 3

[0020] Embodiment three: formulate feed by formula 3 shown in table 1, raise the juvenile yellowfin seabream of 15.3g for 60 days, the feed factor is 1.5, the specific growth rate is 2.08, the survival rate is 98%, and the ammonia nitrogen emission is 9mgkg -1 h -1 , The apparent digestibility of phosphorus is 81%. Compared with the general-purpose freshwater fish compound feed on the market, the specific growth rate has increased by 30%, the feed coefficient has decreased by 20%, and the survival rate has increased by 22%. The apparent digestion of phosphorus The efficiency has been increased by 30%, and the ammonia nitrogen emission is 20% lower than that of the common brackish water fish compound feed on the market.

Abstract

The invention relates to a compound feed for Sparus latus, which comprises the components of (by weight percentage) crude protein 40-50%, crude fat 8-15%, total sugars 15-25%, ash content 6-18%, and water 6-10%. The raw materials of the feed include (by weight portions): protein source raw material 65-80, fat source raw material 4-10, sugar source raw material 10-19, anti-oxidant 0.5, composite vitamin 1.0-2.0 and complex mineral salts 4.5-5.0.

Description

technical field [0001] The invention relates to an environment-friendly compound feed for yellowfin seabream which can improve the growth speed and disease resistance of yellowfin seabream and reduce water environmental pollution. Background technique [0002] Yellowfin seabream (Sparus latus) is an important and valuable brackish water cultured fish in my country. It has a broad market prospect because of its delicious meat, high nutritional value and large economic benefits. However, the current high-density and intensive farming of yellowfin seabream is restricted by two factors. One is that the feed nutrition is not comprehensive, mainly feeding algae, shellfish and fresh miscellaneous fish, etc., and there is no special yellowfin seabream to cooperate with. feed, resulting in slow growth; and algae, shellfish and fresh miscellaneous fish have disadvantages such as unstable supply, difficult storage, nutritional imbalance and high feed coefficient, which will inevitably ...
