Abstract

This experiment was carried out to study the effect of ionophore drugs (Salinomycin, Lasalocid and their combination) on the performance of broiler chicks. Also their relationship with methionine (three levels) was evaluated. 1215 one-day-old commercial broiler chicks (Arian) were divided into 81 groups, 15 chicks per group, and tested in a completely randomized design with a 3×3×3 factorial experiment and three levels (0/0, recommended and 1.5 times recommended) of drugs and three levels (0.0, 1% and 0.2%) of supplemental methionine.

The results indicated that these drugs reduced body weight gain significantly (p<0.05) at 21 and 56 days of the experiment. Decreasing feed consumption and increasing feed conversion was significant (p<0.05) due to Lasalocid supplementation. Increasing drug level significantly (p<0.05) reduced body weight gain and feed intake and feed conversion was increased at 21 to 42 and 0 to 56 days of the experiment. The effect of supplemental methionine on body weight of 42 days (P<0.05) and feed conversion at 21 to 42 and 0 to 56 days (p<0.01) were significant. The interactions between drug type and drug level on body weight gain, feed consumption and feed conversion were significant (p<0.05). Lasalocid significantly (p<0.05) increased water intake. Drugs did not affect litter moisture and mortality. The results showed that Salinomycin was better than Lasalocid. Also supplemental methionine was not effective in compensating for the growth depression caused by ionophore drugs.

Abstract

This experiment was carried out to study the effect of ionophore drugs (Salinomycin, Lasalocid and their combinations) on the performance of broiler chicks. Also their relationships with methionine (three levels) were evaluated. 1215 one-day-old commercial broiler chicks (Arian) were divided into 81 groups, 15 chicks per group, and tested in a completely randomized design with a 3×3×3 factorial experiment. Three drug types with three levels (0.0, the recommended level and 1.5 times the recommended level) of drugs and three levels (0.0, 0.1% and 0.2%) of supplemental methionine were used.

 The results indicated that the effect of sex on plasma cholesterol and triglyceride, percentage of bone ash and percentage of abdominal fat was significant (P<0.0l). Drug type had no effect on the characteristics under study. Drug level influenced percentage of bone ash, percentage of eviscerated carcass, and percentage of abdominal fat significantly (P<0.0l), (P<0.01) and (P<0.00l), respectively. Also methionine level influenced cholesterol and triglyceride (P<0.0l) significantly. Interaction effect of drug type and drug level on plasma cholesterol and triglyceride was significant (P<0.05). Interaction effect of drug and methionine level on cholesterol and triglyceride was significant (P<0.0l). The results showed that levels of this drug influenced carcass composition and also supplemental methionine had no influence on the modulating effect of these drugs on carcass composition.
