preparation example Construction
[0054] A feed preparation method in one embodiment includes steps S110-S150:
[0055] Step S110, in parts by mass, grind 270-440 parts of dehulled soybean meal, 54-66 parts of rapeseed meal and 120-150 parts of corn, and mix with 80-100 parts of fish meal, 45 parts of -55 parts of dephenolized cottonseed protein powder, 90-110 parts of flour and 90-110 parts of expanded soybean flour are mixed to obtain a mixture.
[0056] Specifically, after mixing according to the above proportions, the mixture is uniformly mixed in the first mixer to obtain the mixture.
[0057] In one of the embodiments, after the step of mixing uniformly in the first mixer after batching according to the above proportion, the mixture is also ultrafinely pulverized so that more than 95% of the powder passes through an 80-mesh sieve. The mixture is superfinely pulverized until more than 95% of the powder is passed through an 80-mesh sieve, which can improve the nutrient absorption rate in the prepared feed...
Embodiment 1
[0069] (1) The feed formula composition of the control group, treatment group 1 and treatment group 2 of embodiment 1 is as shown in table 1, and basic feed crude protein is 31%, and crude fat is 8%, energy value is 17.5kJ / g. Treatment group 1 used 1% feed additive instead of filler bentonite on the basis of the control group, and treatment group 2 still added feed additive, but used more low-quality raw materials instead of high-quality raw materials. in:
[0070] Every 100g feed additive consists of 40g mannan oligosaccharide, 2.5g cinnamaldehyde, 2g carvacrol, 5g taurine, 5g vitamin A, 4g vitamin D and 41.5g corn flour.
[0071] Every 1000g vitamin consists of 0.366g vitamin A, 0.1g vitamin D, 2g vitamin E, 2g vitamin K3, 20g niacin, 4g riboflavin, 4g pyridoxine, 4g thiamine, 10g calcium pantothenate, 0.02g biotin, Composed of 1g folic acid, 4g vitamin B12, 20g ascorbic acid, 20g inositol and 908.514g corn starch.
[0072] Every 1000g of trace elements consists of 10g sod...
Embodiment 2
[0087] From May 26th to August 29th, 2018, a big pond breeding experiment was carried out at Wanghai Breeding Demonstration Base, Gujing Town, Xinhui District, Jiangmen City. The formula of the test material is the same as in Example 1. The control group has 9 mu of ponds, 11 mu of treatment group 1 ponds, and 8 mu of treatment group 2 ponds. After feeding about 1 ton of feed per mu, record the situation of selling fish and carry out effect and benefit analysis. Seedlings and fish information are shown in Tables 4-6 below.

[0093]
[0094]
[0095] Compared with the control group, the size of grass carp in treatment group 1 increased by 5%, the feed coefficient of grass carp decreased by 2.8%, and the gross profit increased by 61 yuan / mu; the size of grass carp in treatment group 2 was consistent with that of the control group, and the feed coefficient of grass carp increased by 1.4%, but Due ...
