Problems solved by technology

[0003] However, at present, the research on the special formula feed for triangular bream is almost blank, and the market compound feed mostly adopts the compound feed of other species of fish such as tilapia and roundhead bream
Although this type of feed can provide nutrients, the content and ratio of crude protein, fatty acid, amino acid, carbohydrate, vitamin, mineral and other nutrients in the feed cannot fully meet the needs of triangular bream for these nutrients. And it may cause various waste of resources, environmental pollution, etc. due to problems such as excessive bait coefficient

Embodiment 1

[0017] Example 1: Formula 1 as shown in Table 1 is used to prepare feed (crude protein 32%, crude fat 4%, carbohydrate 25%, ash 8%, moisture 7.5%), and feed about 12.8 g of triangle bream for 60 days. After the experiment, the average weight of this group of triangle bream was about 45.5g, the weight gain rate was 255.05%, the specific growth rate was 2.09, the protein efficiency was 2.07, and the feed coefficient was 1.58. All parameters were consistent with those of the commercial feed group (28% crude protein, 10 crude fiber). %, ash content 18%, moisture content 12%) compared with significantly improved.

Embodiment 2

[0018] Example 2: Formula 2 shown in Table 1 is used to prepare feed (crude protein 35%, crude fat 5%, carbohydrate 20%, ash 8.5%, moisture 8.8%), and feed about 12.8 g of triangle bream for 60 days. After the experiment, the average weight of this group of triangle bream was about 43.8g, the weight gain rate was 243.23%, the specific growth rate was 2.04, the protein efficiency was 1.80, and the feed coefficient was 1.65. All parameters were the same as those of the commercial feed group (crude protein 28%, crude fiber 10 %, ash content 18%, moisture content 12%) compared with significantly improved.

Embodiment 3

[0019] Example 3: Formula 3 shown in Table 1 was used to prepare feed (crude protein 35%, crude fat 4%, carbohydrate 30%, ash 9%, moisture 7.4%), and feed about 12.8 g of triangle bream for 60 days. After the experiment, the average weight of this group of triangle bream was about 41.6g, the weight gain rate was 224.65%, the specific growth rate was 1.94, the protein efficiency was 1.67, and the feed coefficient was 1.79. All parameters were the same as those of the commercial feed group (28% crude protein, 10 crude fiber). %, ash content 18%, moisture content 12%) compared with significantly improved.

[0020] 1. Specific growth rate (%d-1)=100×(ln final body weight-ln initial body weight) / number of experimental days

[0021] 2. Weight gain rate (%) = (final average weight-initial average weight) × 100 / initial average weight

[0022] 3. Feed coefficient = feed amount / (final weight-initial weight)

[0023] 4. Protein efficiency = (final weight-initial weight) / protein dosage

Abstract

The invention discloses triangular bream compound feed, which comprises premixed materials and the following components in mass percent: 31.0-36.0 percent of crude protein, 3.5-6 percent of crude fat, 7-9 percent of ash, 20-30 percent of carbohydrate and 7-9 percent of water. The formula raw materials of the triangular bream compound feed are reasonably selected, the nutrients are balanced, the processing technology is reasonable, the nutrient demands of triangular breams can be fully met, the survival rate and growth speed of the triangular breams, the utilization ratio of the feed and the protein conversion efficiency, immunity and oxidation resistance of fish bodies are improved, and the product quality is improved.

Description

Technical field [0001] The invention relates to a triangular bream compound feed formula, which belongs to the technical field of aquatic compound feed. Background technique [0002] Triangular bream, belonging to the genus Bonefish, Cypriniformes, Cyprinidae, and Bream, is a large wild economic fish, mainly distributed in the middle and lower reaches of the Yangtze River, the Yellow River, Heilongjiang and the eastern coastal water systems. It has a large body and thick flesh, few intermuscular spines, tender and fragrant meat, rich in protein content, and is deeply loved by consumers. It is one of the rare freshwater fishes in my country. Triangular bream is a freshwater fish that lives in the middle and lower strata. It lives in still water with silt and submerged plants. It can grow and reproduce in rivers and lakes. It has a wide temperature range and is intolerant of low oxygen. It requires lean water quality. The triangle bream produced by the Qiantang River is the most f...
