2024-08-30


        Probiotics Additives are biological preparations containing specific probiotics that can promote intestinal health in animals, enhance immunity, and improve digestive function, thereby boosting animal productivity and feed conversion efficiency. By interacting with the microbial communities in the animal’s gut, probiotics help regulate the microecological balance, combat pathogenic organisms, reduce the need for antibiotics, and ultimately achieve the goal of improving animal health and performance.

The Role of Probiotic Additives in Animal Husbandry

  • Promote digestion and absorption Probiotics can break down feed components that are difficult for animals to digest, such as cellulose and proteins, thereby enhancing the nutritional value of the feed and promoting the absorption and utilization of nutrients by animals.
  • Boost immunity Probiotics can stimulate the immune system of animals, enhance their resistance to pathogens, reduce the incidence of disease, and decrease the need for antibiotic use.
  • Improve gut health By regulating the balance of the gut microbiota, probiotics can reduce the incidence of intestinal diseases, decrease digestive problems such as diarrhea, and improve animal growth rates and feed conversion efficiency.
  • Improve production performance Probiotic additives can significantly improve animals' growth rate, feed conversion efficiency, and egg-laying rate, thereby enhancing farming profitability.

Examples of probiotic additive applications

  • Aquaculture In aquaculture, including fish and shrimp farming, probiotic additives can improve water quality, inhibit the growth of harmful microorganisms, promote healthy fish growth, and enhance farming efficiency.
  • Poultry farming By adding probiotic additives, the incidence of intestinal diseases in poultry can be significantly reduced, feed conversion rates can be improved, growth and development can be promoted, and the use of antibiotics can be decreased.
  • Ruminant livestock farming In the raising of ruminant animals such as cattle and sheep, probiotic additives can promote the balance of rumen microorganisms, enhance feed utilization efficiency, and improve animal health and production performance.

Latest experiment

Broiler Glucose Oxidase Experiment

One-day-old Ross 308 broiler chickens were selected, with a total of 4 chicken houses, each housing 11,000 birds. The birds were randomly divided into a control group and a treatment group, with 2 chicken houses assigned to each group. The control group was fed a commercial diet supplemented with Changle (allicin and oregano phenol) at 100 mL/ton, while the treatment group was fed a commercial diet supplemented with glucose oxidase at 100 U/L. During the trial period, birds had free access to feed and water. The trial lasted for 42 days. The experimental diet consisted of corn, soybean meal, wheat, cottonseed meal, DDGS, peanut meal, duck fat, and premixes, among other ingredients; nutritional parameters are shown in Table 1.

Lactic Acid Bacteria Experiment

Effect of Lactic Acid Bacteria on Broiler Diarrhea: A Raising Experiment Experimental Site: Jiyang Zheng* Animal Husbandry Farm Experiment Period: August 31, 2015 – September 4, 2015 Experimental Subjects: 30-day-old broilers Experimental Design: Control Group: Normal feeding + normal drinking water Experimental Group: Normal feeding + normal drinking water + lactic acid bacteria (liquid)

Piglet Fruit Milk Flavor Experiment

Piglet Fruit Milk Flavor Experiment

Twenty 28-day-old weaned piglets of the Duroc × Landrace × Large White crossbreed, with similar body weights and in good health, were selected for the trial. They were randomly divided into two treatment groups: a control group and a test group. The control group was fed a basal diet, while the test group was fed a basal diet supplemented with 600 g/t of fruit-milk flavoring. Each group consisted of five replicates, with two piglets per replicate. During the trial period, the pigs had free access to feed and water, and the trial lasted for 28 days.

The Impact of Tiannuokang as a Substitute for Colistin Sulfate on the Production Performance of Growing-Finishing Pigs and the Microbial Population in Their Feces

In this trial, 120 healthy, growing pigs of similar body condition, weighing 80 ± 10 kg, were randomly divided into a control group, an antibiotic group, and an essential oil group. The specific feeding design is shown in Table 1. Each group consisted of 4 replicates, with 10 pigs per replicate. The trial duration was 29 days. The experimental diet was formulated according to the nutritional requirements outlined in NRC (2012). During the trial, pigs had free access to feed and water, and were subjected to routine husbandry management and vaccination protocols. Body weights at the beginning and end of the trial, as well as feed intake, were recorded. At the end of the trial, fresh fecal samples were collected from each pig, placed into sterile 10 ml centrifuge tubes, and stored at -80℃.

Tian Yikang replaces chlortetracycline in the ROSS-308 trial.

This experiment employed a single-factor experimental design. A total of 6,000 Ross-308 broiler chickens, aged 1 day and with roughly similar body weights and good health conditions, were randomly selected and divided into three treatment groups, with five replicates per group, each replicate consisting of 400 chickens. The control group was fed a basal diet based on corn and soybean meal. The experimental group 1, the antibiotic group, had 50 g/t of a 15% chlortetracycline premix added to the basal diet. The experimental group 2, the Tianyikang addition group, had 1,500 g/t of Tianyikang added to the basal diet. The entire experiment lasted for 42 days.
