example 1

[0020] Example 1: Early implementation (feed suitable for broiler chickens aged 1 to 21 days):

[0021] 1. Weigh the raw materials of the basic diet: 54.5kg of corn, 35.2kg of soybean meal, 3.18kg of corn gluten meal, 2.65kg of soybean oil, 1.35kg of stone powder, 0.17kg of DL-methionine, 0.08kg of L-lysine, calcium hydrogen phosphate 2kg, salt 0.35kg, multidimensional 0.03kg, multimineral 0.3kg, trace 0.2kg, 50% choline chloride 0.26kg, antioxidant 0.03kg. The above total amount is 100kg.

[0022] 2. Prepare feed for each group:

[0023] Low SF68 Enterococcus faecium group (LEF): The ratio of SF68 Enterococcus faecium to basal diet: 50mg: 1kg.

[0024] Medium SF68 Enterococcus faecium group (MEF): The ratio of SF68 Enterococcus faecium to basal diet: 100mg: 1kg.

[0025] High SF68 Enterococcus faecium group (HEF): The ratio of SF68 Enterococcus faecium to basal diet is: 200mg: 1kg.

[0026] Antibiotic group (Ant): the proportion of aureomycin in the basal diet was 0.1%. ...

[0028] Example 2: Late implementation (feed suitable for broiler chickens aged 22 to 42 days):

[0029] 1. Weigh the raw materials of the basic diet: 60.3kg of corn, 30.2kg of soybean meal, 2kg of corn gluten meal, 3.52kg of soybean oil, 1.35% of stone powder, 0.1kg of DL-methionine, 0.075kg of L-lysine, 1.65 kg of calcium hydrogen phosphate kg, salt 0.35kg, multidimensional 0.025kg, multimineral 0.3kg, trace 0.2kg, 50% choline chloride 0.2kg, antioxidant 0.03kg.

[0030] 2. Prepare feed for each group:

[0031] Low SF68 Enterococcus faecium group (LEF): The ratio of SF68 Enterococcus faecium to basal diet: 50mg: 1kg.

[0032] Medium SF68 Enterococcus faecium group (MEF): The ratio of SF68 Enterococcus faecium to basal diet: 100mg: 1kg.

Abstract

The invention relates to an antibiotic-free feed for broiler chickens, and belongs to the technical field of animal feed processing. The antibiotic-free feed is mainly made from basic ration and SF68 enterococcus faecium. According to the feed for the broiler chickens, the SF68 enterococcus faecium is added, experiments prove that the feed-weight ratio of the broiler chickens can be decreased to 1.37, the growth performance of the broiler chickens is improved, and the feed replaces antibiotics to some extent.

Description

technical field [0001] The invention belongs to the technical field of animal feed processing. Background technique [0002] In recent years, probiotics have been increasingly used in animal husbandry. It can not only improve animal immunity, promote healthy growth of animals, but also avoid the side effects of antibiotics and other drugs. Enterococcus faecium, formerly known as Streptococcus faecalis, is a bacterial source that can be used to produce feed microecological preparations as stipulated by the Ministry of Agriculture, and is known as a star strain in livestock and poultry feed microecological preparations. After the microecological preparation made by a series of processes is fed to the livestock and poultry with the feed, it is beneficial to improve the microecological balance in the intestinal tract, prevent the disorder of the intestinal flora of animals, and can also decompose proteins into small peptides and synthesize group B vitamins etc. It can also enh...
