By: The Food and Drug Administration (FDA) has recently approved a number of animal drugs, including those that treat bacterial enteritis in replacement beef and dairy heifers, according to a press release from the American Veterinary Medical Association.
On October 13, the FDA approved Aivlosin Water Soluble Granules (WSG)—62.5% w/w tylvalosin as tylvalosin tartrate—for female swine intended for breeding, such as replacement gilts, gestating replacement gilts, gestating sows, lactating sows, and weaned sows.
Aivlosin is an antimicrobial drug, available by prescription from a licensed veterinarian, that is administered continuously at 50 ppm tylvalosin in drinking water for five consecutive days. It is available in 160 g and 400 g sachets.
The drug is approved for the control of porcine proliferative enteropathy associated with Lawsonia intracellularis infection and control of swine respiratory disease (SRD) indications associated with Bordetella bronchiseptica, Glaesserella (Haemophilus) parasuis, Pasteurella multocida, Streptococcus suis, and Mycoplasma hyopneumoniae in groups of swine intended for slaughter and female swine intended for breeding in buildings experiencing an outbreak of SRD.
Prior to this approval, the label indication restricted Aivlosin WSG to be used only in the drinking water of swine intended for slaughter. The drug remains not available for use in male swine intended for breeding.
Aivlosin is sponsored by ECO Animal Health Group, based in Princeton, New Jersey, and sold by Pharmgate Animal Health.
Estroplan for dairy cows
On September 20, the FDA approved Estroplan, an injectable cloprostenol solution for dairy cows. This supplement is indicated for use with gonadorelin to synchronize estrous cycles to allow for fixed time artificial insemination in lactating dairy cows.
Estroplan is available by prescription from a licensed veterinarian and is supplied in 20 mL and 100 mL multidose vials.
Estroplan is sponsored by Parnell Technologies, based in New South Wales, Australia.
