Supplementation with lasalocid three times weekly to stocker cattle on pasture

Two experiments were conducted to study the efficacy of feeding lasalocid to cattle on pasture on a three times weekly basis. In experiment 1, 72 crossbred yearling steers were stratified across a randomized block design of 12 pens including three ...

Determination of regulatory ionophore coccidiostat residues in feedstuffs at carry-over levels by liquid chromatography-mass spectrometry.

PLoS ONE, 2017
In this study samples of feedstuffs were collected from different feed mills and animal farms located in central Italy and analyzed for ionophore coccidiostat residues at carry-over levels by liquid chromatography-mass spectrometry.

Effects of energy level and lasalocid on productivity of fall-calving,first-calf heifers [PDF]

, 1987
Fall-calving, first-calf heifers (136 head) were fed TDN levels approximating 85% or 100% of NRC recommendations, with or without 200 mg/hd/day lasalocid.

Effects of Rumensin or Lasalocid on rumen fermentation in vitro [PDF]

, 1979
A series of artificial-rumen studies tested effects of Rumensin and lasalocid on rumen fermentation. At concentrations of 22, 44, and 66 ppm both depressed microbial protein synthesis. Both severely inhibited protein synthesis at 176 ppm.

Bepaling van lasalocid-natrium door middel van HPLC [PDF]

, 1981
Lasalocid-natrium is volgens methode EEG doc. 1089/VI/81-E onderzocht in twee mengvoeders. De storende invloed van monensin, salinomycine en narasin werd eveneens bekeken. Lasalocid-natrium wordt als coccidiostaticum toegepast voor het gebruik van kippen

Association of corn processing methods and sodium lasalocid for beef cattle on pasture during the finishing phase

We aimed to investigate the effects of corn processing methods and lasalocid in grazing cattle receiving high levels of concentrate on ruminal parameters, performance, and meat quality. Twelve cannulated animals were utilized to assess ruminal metabolism

Intriguing Substrate Tolerance of Epoxide Hydrolase Lsd19 Involved in Biosynthesis of the Ionophore Antibiotic Lasalocid A

, 2016
Recently, we reported that the epoxide hydrolase Lsd19, the first enzyme shown to catalyze epoxide-opening cascades, can catalyze the conversion of a putative bisepoxide intermediate to polyether antibiotic lasalocid, which involves energetically ...

Effects of heat stress and lasalocid on the acid-base balance of cattle [PDF]

, 1989
Two questions were proposed in these studies. One, does lasalocid contribute to respiratory alkalosis and thus to bloat? Two, are there mechanisms of action other than the typical ruminal effects?
