Chicken probiotics, Clostridium butyricum

What is the proportion of Clostridium butyricum added to chicken feed?

      The proportion of Clostridium butyricum added to chicken feed should be determined based on the growth stage of the chicken, the type of feed, and the product formulation (such as the concentration of live bacteria). The following are common reference ranges and precautions:

1、 Recommended addition ratios for different growth stages

      Chick stage (1-42 days old)

      Objective: To promote intestinal development and establish microbial balance.

      Recommended dosage: Add 1 × 10 ⁷ -5 × 10 ⁸ CFU (colony forming units) per kilogram of feed.

Chicken breeding stage (from 43 days old to onset of production)

      Objective: To maintain intestinal health and improve feed utilization efficiency.

      Recommended dosage: Add 5 × 10 ⁶ -1 × 10 ⁸ CFU per kilogram of feed.

laying period

      Objective: To enhance stress resistance and improve eggshell quality.

      Recommended dosage: Add 1 × 10 ⁷ -3 × 10 ⁸ CFU per kilogram of feed.

2、 Key factors affecting the addition ratio

Product viable bacterial concentration

      The live bacterial count of Clostridium butyricum preparations from different manufacturers varies greatly (such as 10 ⁹ CFU/g vs. 10 ¹⁰ CFU/g), and the dosage should be calculated according to the product manual.

      Example: If the live bacterial content of a product is 1 × 10 ¹⁰ CFU/g, 0.1-0.5 g should be added per kilogram of feed during the chick stage.

Feed type

      Full price compound feed: directly mixed in proportion;

      Premix: it shall be diluted with carrier (such as corn flour) before adding, so as to avoid local high concentration.

Health status and stress scenarios

      During the onset of the disease or under stress conditions such as population transition or immunity, the dosage can be increased by 20% -30% in the short term to enhance intestinal repair.

3、 Precautions

      Avoid co use with antibiotics: Clostridium butyricum is a live bacterial preparation and should be used 2-3 hours apart from antibiotics to prevent its activity from being inhibited.

      Storage conditions: Sealed and stored in a cool and dry place, avoiding high temperature and humidity that may cause the inactivation of live bacteria.

      Professional consultation: When using or adjusting the formula for the first time, it is recommended to contact feed factory technicians or veterinarians to customize the plan according to actual breeding needs.

      In practical applications, it is necessary to take the recommended dosage of specific products as the core basis, while also flexibly adjusting the status of the chicken flock to achieve optimal benefits.
