Toxins in feed, including toxic strains and toxic metabolites, can lead to stunted growth, acute and chronic toxicity, reduced reproductive performance, reduced feed utilization, cancer, and genetic mutations in animals. The consumption of livestock products (meat, eggs, milk, etc.) and agricultural products with accumulated toxin residues can also affect human health. Therefore, toxicological testing of toxic strains in feeds and fertilizers is very crucial.
Lifeasible provides toxicological testing services to meet the needs of our customers in a wider range of feed and fertilizer production and improvement fields. We perform animal studies to determine the toxicity level of feed and fertilizer products to help you improve your production process or formulation. Our goal is to help you improve the palatability of feed, improve the utilization of feed and fertilizer, and maintain the health of livestock and agricultural products.
- Acute oral toxicity test. According to the LD50 value to determine the acute toxicity classification of the test substance.
- A broken skin irritation test. Test the irritation/corrosion effect and intensity of the test substance on the skin of experimental animals.
- Acute intraperitoneal injection pathogenicity test. To detect acute pathogenicity of the test substance.
- Acute ocular irritation test. To detect the acute irritation and corrosive effect of the test substance on the eyes of experimental animals.
- Hemolysis test. To detect the hemolytic property of the subject by observing whether there is a β-hemolytic ring or α-hemolytic ring around the colony.
- Antibacterial drug sensitivity test. To detect the strength of susceptibility of the subject to antimicrobial drugs.

- Feed for livestock and poultry
Toxic or pathogenicity test results do not meet the strains, and shall not be used as microbial fertilizer, or feed production strains. Toxicology test results of the evaluation of toxic products, but also shall not be produced and sold. Therefore, Lifeasible's biofertilizer and feed toxicology testing service can provide you with more informative test results. You can better evaluate the quality of your products and make improvements. Please contact our staff to submit a service request for testing. We are ready to provide you with customized testing solutions.
