Resumo: | The large utilization of coccidiostats in dairy herds has raised the question regards the best product to use, based on better animal performance. Sixty-four Holstein calves were randomly assigned to four treatments at 10 (±4) d of age to evaluate calf performance when fed approved coccidiostats available on the market in Arizona, USA. Calves received a dry calf starter without (control) or with one of the following coccidiostats: lasalocid, 30 mg kg-1; decoquinate, 19 mg kg-1; and monensin, 30 mg kg-1. Calves received 3.6 kg d-1 of a commercial 22% CP:20% fat milk replacer until 6 wk of age. Calves were offered starter "ad libitum" up to 2 kg d-1, and calves had free access to water throughout the trial. Alfalfa hay was offered "ad libitum" after weaning. Performance and dry matter intake (DMI) were monitored for 20 weeks and broken down in different periods of measurement (0-6, 7-12 and 13-20 weeks, respectively). Despite the lower dry matter intake and weight gain for females on monensin treatment during the whole period, differences among coccidiostats were seldom observed under the conditions of this study. Good calf management and the dry, hot climate of Arizona perhaps diminished the chances for subclinical and chronic disease appearance which negated potential differences and differences in calf performances.
