Embodiment 1~3
[0021] Examples 1~3 (1) Antibiotic-free broiler chicken feed, made from the following raw materials in parts by weight:
[0022]
[0023] The specific raw materials of Example 1 will be described below. The grain of the broiler broiler brooding period compound feed is corn; the calcium element additive of the broiler broiler brooding period compound feed is 1.5 parts of calcium carbonate and 1.7 parts of calcium hydrogen phosphate; The broiler broiler brooding period compound feed contains 0.21 parts of lysine and 0.1 part of methionine; the broiler broiler brooding period compound feed contains VA 0.004 parts, VD3 0.0005 parts, VK3 0.0002 parts, VB1 0.0003 parts, and VB2 0.0008 parts. , VB6 0.0006 parts, VB12 0.0004 parts, VE 0.015 parts, folic acid 0.0005 parts, nicotinamide 0.005 parts, biotin 0.0002 parts, calcium pantothenate 0.0015 parts, rice husk carrier 0.051; the compound trace elements of the broiler broiler brooding period compound feed are 0.003 parts of copper sulfa...
experiment example
[0030] Experimental example Examples 1~3 were used to prepare antibiotic-free broiler feed for the following verification
[0031] In order to verify the scientificity and practicality of the present invention, three feeding experiments were done for this purpose, as follows:
[0032] Experiment 1
[0033] The feeding experiment was carried out in the Dongshun experimental chicken farm. The broiler broiler broiler broiler broiler compound feed and the broiler mid-to-large broiler mid-to-large broiler compound feed that were recognized by the broiler breeders at the time were selected as the control group, and the label of the control product contained enramycin At 8 mg / kg, the test group was fed the compound feed for the antibiotic-free broiler chickens of Example 1 of the present invention.
[0034] Test 2
[0035] The feeding experiment was carried out in the Dongshun experimental chicken farm. The experimental group was fed with the compound feed for the antibiotic-free broiler chic...
Embodiment 2
[0046] In Example 2, compared with the control group, the average weight of the test group at the 2nd and 6th weekends was increased by 36.29g and 328g, and the feed-to-meat ratio was reduced by 7.74% and 11.59% respectively; 1.83 times. According to the above data, it can be concluded that the test group is significantly better than the control group in terms of production performance and death rate, which shows that oligosaccharides, acidulants, Bacillus subtilis, pepper, pine leaf powder, garlic, wild jujube kernels and flue-cured tobacco seeds Combined use can significantly enhance the immune function of broilers, increase survival rate and slaughter weight, thereby improving economic benefits.
