Feed Additive

Tylosin is a kind of veterinary macrolide antibiotics commonly used in China, also known as tyronon and tylosin. It can be obtained by fermentation of actinomycetes Streptomyces Freund. There are three forms of tylosin alkali, phosphate and tartrate. The antibacterial spectrum is similar to erythromycin. It has inhibitory effects on Gram-positive bacteria and some Gram-negative bacteria, mycoplasma, Vibrio, coccidia and spirochetes. It is particularly effective on mycoplasma, but its effect on Gram-positive bacteria is not as good as erythromycin. This product is characterized by its strong effect on mycoplasma. It is one of the drugs with the strongest anti Mycoplasma effect among macrolides. As a feed additive, it is widely used in the feed of chickens, pigs, cattle, sheep, fish, shrimp and other animals, which can promote the growth of livestock and poultry and improve the feed utilization rate. It is mainly used to control Mycoplasma disease in chickens, turkeys and other animals; Vibrio dysentery and infectious pleuropneumonia in pigs are also used for enteritis, pneumonia, mastitis and endometritis caused by sensitive bacteria. The effect of subcutaneous injection is better than that of oral administration in the treatment of chicken chronic respiratory diseases. The tissue drug concentration after subcutaneous injection is 2 ~ 3 times higher than that of oral administration, and the maintenance time of effective blood drug concentration is also longer. In addition, tylosin phosphate is also used as a growth promoting drug feed additive for cattle, pigs and chickens. There is cross resistance between this product and erythromycin.

N-alpha-fluoromethoxycarbonyl-N-in-tert butoxycarbonyl-L-tryptophan is a tryptophan derivative that can be used to prepare various organic functional molecules with biological activity. It has a wide range of applications in basic biochemical research, such as the synthesis of solid-phase peptides as reported in relevant literature.

D-aspartic acid is the D-enantiomer of aspartic acid. It has a role as a mouse metabolite. It is an aspartic acid and a D-alpha-amino acid. It is a conjugate acid of a D-aspartate(1-). It is an enantiomer of a L-aspartic acid. This product is a precursor and intermediate for the synthesis of chiral drugs.

This product has a good preventive effect on chicken cecal coccidia, Eimeria cumulus, Eimeria gigantica, Eimeria poisoning and Eimeria borrelii. It has the advantages of high efficiency, low toxicity, stable performance and low drug resistance. This product can be used in combination with coccidial ester, and the effect is better.

This product is a nutritional enhancer and a new calcium supplement, which is easier to be absorbed by the human body than other calcium supplements.
