Embodiment 1
[0026]The preferred weight percentages of the raw materials in the protein-saving formula feed for young bream juveniles provided by the invention are: 3% fish meal, 20% soybean meal, 15% rapeseed meal, 10% cotton meal, 10% peanut meal, and full-fat puffed soybean 4%, full-fat rapeseed 6%, fermented cottonseed meal 5%, corn distiller's grain protein 4%, wheat bran 10%, subflour 9%, bile salt emulsifier 0.1%, glycyrrhetinic acid 0.03%, α-starch 1.87% , calcium dihydrogen phosphate 1% and intensive fish compound premix 1%. It contains the following nutrients and levels: moisture 10%, crude protein 31%, crude fat 6%, digestible sugar 33%, total energy 18.6MJ / kg, egg energy ratio 17.1g / MJ, glycolipid ratio 5.5, crude ash 9 %, crude fiber 11%.
[0027] The method for making the compound feed from the formula of the protein-saving juvenile bream compound feed provided by the invention is carried out according to the following steps:
[0028] A, take by weighing above-mentioned var...
Embodiment 2
[0035] A. Take 0.3 kg of fish meal, 2.0 kg of soybean meal, 1.4 kg of rapeseed meal, 1.0 kg of cotton meal, 1.0 kg of peanut meal, 0.5 kg of full-fat puffed soybean, 0.6 kg of full-fat rapeseed, 0.6 kg of fermented cotton meal, and 0.4 kg of corn distiller's grain protein kg, 0.9 kg of wheat bran, 0.9 kg of secondary powder, 0.01 kg of bile salt emulsifier, 0.003 kg of glycyrrhetinic acid, 0.187 kg of α-starch, 0.1 kg of calcium dihydrogen phosphate and 0.1 kg of intensive fish compound premix, of which phosphoric acid Calcium dihydrogen and intensive fish compound premix were purchased from Nanjing Huamu Animal Science and Technology Research Institute in Jiangsu Province; it contained the following nutrients and levels: moisture 11%, crude protein 28%, crude fat 8%, digestible sugar 32% , total energy 16.5MJ / kg, egg energy ratio 17.1g / MJ, glycolipid ratio 4, crude ash 9.5%, crude fiber 12%.
[0036] B. Separately crush raw materials such as soybean meal, rapeseed meal, cotto...
Embodiment 3
[0041] Embodiment 3: basically the same as Example 1, the difference is the raw material formula, the weight percentages of each raw material are respectively: fish meal 5%, soybean meal 22%, rapeseed meal 10%, cotton meal 15%, peanut meal 8%, whole Fat puffed soybean 3%, full-fat rapeseed 5%, fermented cottonseed meal 8%, corn distiller's grain protein 3%, wheat bran 8%, subflour 9%, α-starch 1.93%, bile salt emulsifier 0.05%, licorice Hypoacid 0.02%, calcium dihydrogen phosphate 1% and intensive fish compound premix 1%.
