Control of coccidia in young calves using lasalocid

Australian Veterinary Journal, 1995
SUMMARY Thirty‐six, 2‐ to 4‐day‐old Friesian bull calves were divided into 4 groups and fed milk replacer and calf starter pellets ad libitum in separate pens. Four treatments were applied; lasalocid in milk (1 mg/kg body weight/day) (M), lasalocid in starter (F), lasalocid in both milk and starter (M+F) and untreated (C).

Effects of adaptation to lasalocid, monensin or a daily rotation of lasalocid and monensin on in vitro fermentation of a 90% concentrate diet

Canadian Journal of Animal Science, 1995
Effects of adaptation to L, M or a daily rotation of L and M (R) on in vitro fermentation were measured in a replicated in vitro experiment with a 4 × 4 factorial arrangement of treatments. Treatments were adaptation of ruminal fluid donor steers (0 or 200 mg steer−1 d−1 of L, M or R) and culture ionophore treatment (0 or 4 μg mL−1 of L, M or a 50:50 ...

The solution structure of a lasalocid A metal complex in lipophilic solvents

Bioorganic & Medicinal Chemistry, 2005
Lasalocid A (LasNa), a common antibiotic in veterinary medicine, is a polyetheral ionophore, disrupting cation equilibria through the cell wall. By means of circular dichroism (in the UV and in the near-IR), paramagnetic NMR, and with the aid of the program PERSEUS, we determined the solution geometry of the 1:1 Las-Yb3+ complex in CD3CN and CDCl3 ...

Thermodynamic analysis of amines-lasalocid complex formation

Biophysical Chemistry, 1997
The ionophore lasalocid A selectively transports amines across lipid membranes. Free energy differences of amine-lasalocid complex formation reactions and the activation barriers of the complex transport were calculated by the finite difference thermodynamic integration method.

Prevention of Lactic Acidosis in Cattle by Lasalocid or Monensin

Journal of Animal Science, 1981
Intraruminal administration of lasalocid or monensin (1.3 mg/kg body weight) effectively prevented in glucose- or corn-induced lactic acidosis in cattle. Administering the antibiotics for 7 days before experimentally inducing acidosis with corn (27.5 g/kg body weight), effectively prevented acidosis, while 2 days' were sufficient to prevent glucose ...

Suspected lasalocid poisoning in three dogs.

Veterinary and human toxicology, 2003
The ionophore lasalocid has been used as a feed additive for broilers chickens and for improving feed efficiency in ruminants. Although dogs appear to be more sensitive to lasalocid intoxication than other species, there is only 1 report in the veterinary literature about lasalocid poisoning in dogs.

Lasalocid toxicosis is inadequately quantified for horses.

Veterinary and human toxicology, 2002
The current estimate of LD50, 21.5 mg/kg BW, for lasalocid in horses is based on an analysis of 8 data from 4 horses that died at dose levels of 15, 21, 22 and 26 mg/kg. This analysis neglected 14 data from another 6 horses that survived at dose levels of 5, 10,14, 18, 19, 25, 29 and 50 mg/kg, and so was biased by selection of data.
