Chicken farming tips: adding Bacillus subtilis

Bacillus subtilis has various functions and advantages when used for feeding chickens. The following is a detailed introduction for you:

The impact on chicken intestinal health

Regulating the balance of gut microbiota: Bacillus subtilis can quickly germinate and reproduce in large quantities after entering the chicken gut. By secreting various antibacterial substances such as bacteriocins and lipopeptides, it inhibits the growth of harmful bacteria (such as Escherichia coli and Salmonella) in the gut, reduces the invasion and damage of harmful bacteria to the chicken intestinal mucosa, and lowers the risk of intestinal diseases. At the same time, it can also create a more suitable living environment for beneficial bacteria (such as bifidobacteria, lactobacilli, etc.), promote the proliferation of beneficial bacteria, make the structure of intestinal microbiota more reasonable and stable, and maintain a good microecological balance.

Improving intestinal digestion function: This bacterium can produce various digestive enzymes, such as protease, amylase, cellulase, etc. These enzymes help to decompose protein, starch, cellulose and other components in chicken feed, allowing nutrients in the feed to be more fully released, facilitating better absorption and utilization in the chicken intestine, improving the digestibility and conversion rate of feed, reducing waste caused by undigested feed being discharged from the body, and thus reducing breeding costs and improving breeding efficiency to a certain extent. Moreover, in a healthy intestinal environment, the intestinal villi of chickens will develop better, further enhancing their absorption capacity.

Enhancing the immune system of chickens

Activation of immune cells: Bacillus subtilis can stimulate the immune system of chickens, activate the activity of immune cells (such as macrophages, T lymphocytes, etc.), enable them to better recognize and engulf foreign pathogens, and enhance the innate immune defense ability of chickens. For example, when chickens are faced with the threat of external bacterial infection, the immune system regulated by Bacillus subtilis can respond more quickly to reduce the incidence rate and mortality of chickens.

Inducing immune response: It can induce chickens to produce specific immune responses, promote the secretion of immunoglobulin and other antibodies, improve the specific immune level of the chicken body, make the chicken have stronger resistance to the same pathogen in the future, enhance the overall disease resistance of the chicken, reduce the use of antibiotics and other drugs to prevent and treat diseases, and conform to the concept of green farming.

Promoting the growth performance of chickens

Increasing feed intake: Due to the improvement of chicken intestinal health and digestive function by Bacillus subtilis, the palatability of feed will also be enhanced, and chickens will be more willing to feed. Feed intake can be increased, ensuring that chickens consume sufficient nutrients to meet their growth and development needs.

Promoting growth rate: Chickens can better digest and absorb nutrients from feed, which can be effectively converted into the necessary tissues for their own muscle, bone, and other growth, thereby accelerating their weight gain. In broiler farming, this can shorten the slaughter time and increase slaughter weight; For laying hens, it helps to maintain good egg laying performance, increase egg production rate and weight, and improve the quality of eggs, such as stronger eggshells and brighter yolk colors.

Usage and precautions

Addition method: Bacillus subtilis preparation can be directly added to chicken feed, mixed evenly according to a certain amount of addition, and allowed to be ingested by chickens during the feeding process. It can also be prepared into a bacterial solution and supplied to chickens through drinking water, but attention should be paid to the concentration and storage conditions of the bacterial solution to ensure its activity.

Addition amount: Generally, the addition amount in chicken feed is about 0.1-0.5 grams per kilogram of feed. Specific adjustments should be made according to the breed, growth stage (such as chicks, breeding chickens, laying hens, broiler chickens, etc.), and breeding environment of the chicken to avoid insufficient addition that cannot achieve the desired effect, or excessive addition that may have adverse effects on the chicken's intestines.

Product quality: It is necessary to choose Bacillus subtilis products produced by legitimate manufacturers, with qualified quality, high and stable bacterial activity. Check the identification information such as effective live bacteria count, shelf life, and storage conditions of the products to ensure that the products used can truly play their due role.

      In summary, Bacillus subtilis is a valuable microbial preparation in chicken farming, and its scientific and rational application can bring many benefits to the health, growth, and breeding efficiency of chickens.
