The exponential growth of global demand for livestock products has led to the rapid development of the livestock industry, and also caused the tension and shortage of feed resources (especially protein resources) needed for raising livestock and poultry. This requires us to develop newly available protein feeds.
Lifeasible can provide customers with single-cell protein feed, fermented protein feed, enzymatic protein feed, oligopeptide feed, and some other protein feeds (high-quality protein corn, double low vegetable meal, low phenol cottonseed cake meal, Cyamopsis tetragonoloba, etc.) to meet your different needs.
- Production of single-cell protein feeds from wastewater waste streams.
- In vitro enzymatic production of oligopeptide feed additives (soybean, corn yellow meal, soybean-corn compound, aquatic animal protein enzymatic digestion, etc.).
- Microbial fermentation of straw feed.
- Livestock and poultry manure fermentation and regeneration feed (fermented chicken manure, cow manure).
- Cake meal feed (cottonseed cake meal, rapeseed cake meal), and the use of waste meal materials to produce fermented feed.
Successful case: Hydrolyzed protein mixture and protein-peptide powder feed additive development solution
We prepare hydrolyzed protein mixture and peptide powder by enzymatic hydrolysis of vegetable protein with a multi-enzyme compound. Its process is simple and the compounding of non-starch polysaccharide enzymes and proteases can improve the speed and degree of protein hydrolysis, increase feed utilization and reduce production costs. The product obtained by our provided solution can be used as a feed additive to significantly improve the egg production rate of egg-laying birds, increase the weight gain of meat birds, reduce the feed-to-meat ratio and improve the production performance of broilers. It can also reduce the incidence of diarrhea in young animals and reduce the feed-to-meat ratio of piglets. When used in aquatic animals, it can improve the weight gain of fish, reduce the bait coefficient and lower the viscosity of intestinal contents.
In addition to the development of new protein feeds, we also provide safety evaluation of new protein feeds. After empirical studies such as animal tests and feedback from customers' use, we evaluate the animal's appetite attractiveness, growth performance, and immunity.
General procedures for safety toxicology evaluation
| Phase I |
Acute toxicity test. |
- Transoral acute toxicity: LD50, combined acute toxicity.
|
| Phase II |
Genotoxicity test, traditional teratogenicity test, short-term feeding test. |
- Bacterial mutagenicity test: The Salmonella typhimurium/mammalian microsomal enzyme test (Ames test) is the preferred test, with additional tests selected and added if necessary.
- Bone marrow micronucleus rate determination or chromosomal aberration analysis of bone marrow cells in mice.
- Sperm aberration analysis and testicular chromosome aberration analysis in mice.
- Other alternative genotoxicity tests: V79/HGPRT gene mutation test, dominant lethal test, Drosophila companion recessive lethal test, and extra-procedural DNA repair synthesis (UDS) test.
- Traditional teratogenicity test.
- Short-term feeding test: 30d feeding test. This test may be dispensed with if the subject is subjected to a phase III or IV toxicity test.
|
| Phase III |
Subchronic toxicity test: 90d feeding test, reproduction test, metabolism test. |
| Phase IV |
Chronic toxicity test (including carcinogenicity test). |
