Problems solved by technology

At present, due to the one-sided pursuit of output and growth rate, and the lack of detailed and in-depth research institutes for soft-shelled turtles, feed manufacturers use high-protein feeds in soft-shelled turtle compound feeds (the crude protein content of juvenile and young turtle compound feeds is 47% respectively. and more than 46%), the content of fish meal used in the compound feed is 50-60%, and the phosphorus content in the imported white fish meal is very high (the phosphorus in the imported white fish meal is more than 3.5%), forming a soft-shelled turtle compound feed with high nitrogen, high The characteristics of phosphorus, so the current commercial feed is not an environmentally friendly feed, which is not good for the sustainable development of the soft-shelled turtle industry chain

Embodiment 1

[0017] An environment-friendly soft-shelled soft-shelled turtle compound feed is composed of the following raw materials by weight: white fish meal 35%, red fish meal 19%, fermented soybean meal 7%, puffed soybean 4%, gluten 2%, brewer's yeast 8%, Pregelatinized starch 21.6%, calcium dihydrogen phosphate 1.5%, enzyme preparation 0.15%, microbial preparation 0.1%, compound multidimensional 0.25%, compound polymine 1%, 50% choline chloride 0.4%. These raw materials are mixed and pulverized, and 100% pass through an 80-mesh sieve, which is an environment-friendly soft-shelled soft-shelled turtle compound feed. The proportion of feed ingredients in this example is reasonable, wherein the crude protein is 44.2%, and the phosphorus is 2.18%.

[0018] The juvenile soft-shelled turtle compound feed of the control group consists of the following raw materials by weight: 41% white fish meal, 20% red fish meal, 3% soybean meal, 4% expanded soybean, 2% gluten powder, 8% brewer's yeast, pr...

Embodiment 2

[0023] An environment-friendly compound feed for soft-shelled soft-shelled turtles, which consists of the following raw materials by weight: 31% white fish meal, 20% red fish meal, 8% fermented soybean meal, 5% puffed soybean, 2% gluten powder, 7% brewer's yeast, Pregelatinized starch 23.7%, calcium dihydrogen phosphate 1.5%, enzyme preparation 0.1%, microbial preparation 0.2%, compound multidimensional 0.2%, compound multimineral 1%, 50% choline chloride 0.3%. After these raw materials are mixed, they are superfinely pulverized and passed through an 80-mesh sieve to become an environment-friendly compound feed for juvenile soft-shelled turtles. The proportion of feed ingredients in this example is reasonable, wherein the crude protein is 43.1%, and the phosphorus is 2.06%.

[0024] The soft-shelled soft-shelled turtle compound feed of the control group consists of the raw materials of the following weight components: white fish meal 38%, red fish meal 20%, soybean meal 4%, ex...

Embodiment 3

[0029] An environment-friendly soft-shelled soft-shelled turtle compound feed is composed of the following raw materials by weight: white fish meal 33.6%, red fish meal 21.3%, fermented soybean meal 7.2%, puffed soybean 4.3%, gluten 2%, brewer's yeast 8.4%, Pregelatinized starch 19.7%, calcium dihydrogen phosphate 1.5%, enzyme preparation 0.2%, microbial preparation 0.15%, compound multidimensional 0.25%, compound polymine 1%, 50% choline chloride 0.4%.

[0030] The feed of this embodiment was used for soft-shelled turtle breeding in Tonglu, Zhejiang Province. The farmers reported that the water quality in the breeding process was more stable than when other feeds were used before, the amount of water exchange was significantly reduced, the growth rate of soft-shelled turtles was normal, and the common diseases of soft-shelled turtles were significantly reduced.

Abstract

The invention discloses an environmentally-friendly soft-shelled turtle compound feed, including the following material components (each component is in the air-dry substance weight percentage): 30-35% of white fish meal, 15-25% of red fish meal, 5-10 % of fermented soybean mea, 3-6% of extruded soybean, 1-4% of wheat gluten, 5-10% of beer yeast, 18-25% of pre-gelatinized starch, 1-2% of calcium phosphate, 0.05-0.3% of enzyme preparation, 0.1-0.4% of microbial agents, 0.1-0.3% of compound multivitamins, 0.5-1.5% of composite multi-ore, 0.2-0.5% of 50% choline chloride. The inventive prescription can reduce the nitrogen and phosphorus content in the compound feed, improve the digestive absorption and deposition rate of the nitrogen and phosphorus in the soft-shelled turtle breeding, and can reduce the output of nitrogen and phosphorus in water to improve the breeding environment.

Description

【Technical field】 [0001] The invention relates to aquaculture feed, in particular to an environment-friendly soft-shelled turtle compound feed. 【Background technique】 [0002] Soft-shelled turtle has the function of nourishing and strengthening the body, prolonging life, and has high nutritional value. It is a traditional nourishing aquatic product in my country and has always been loved by the people of our country. Since the 1990s, soft-shelled turtle farming in my country has developed rapidly, and the scale of farming has expanded, becoming one of the main species of aquaculture in my country. At present, soft-shelled turtles are cultured mainly in greenhouses and ponds. However, these two existing modes of soft-shelled turtles are one-sided in pursuit of production and the output of soft-shelled turtles per unit of water. They often use high-protein soft-shelled turtle compound feed and overfeed. The use of high-density farming has resulted in the accumulation of resid...
