Control of coccidia in young calves using lasalocid
Australian Veterinary Journal, 1995SUMMARY 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).

The solution structure of a lasalocid A metal complex in lipophilic solvents
Bioorganic & Medicinal Chemistry, 2005Lasalocid 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 ...

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 ...

Lasalocid toxicosis is inadequately quantified for horses.
Veterinary and human toxicology, 2002The 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.
