Example

[0020] Example 1: Early implementation (suitable for broilers from 1 to 21 days old):

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

[0022] 2. Prepare each group of feed:

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

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

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

[0026] Antibiotic group (Ant): Chlortetracycline accounts for 0.1% of the basal diet. ...

Example

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

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

[0030] 2. Prepare each group of feed:

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

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

[0033] High SF68 Enterococcus faecium group (HEF): The ratio of SF68 Enterococcus faecium to the basal diet is: 200mg:1kg.

[0034] Antibiotic group (Ant): Chlortetracycline accounts for 0.1% of the basal diet.

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...
