Weighing calves also provides a measure of the value of specific milk replacers together with other variables such as season, source of calves and current management. To allow early detection of disease and easier treatment with less stress, newly purchased or weaned calves should be housed in groups of 10 or less. They should also be separated from existing calves for at least one month. It is important, especially in cold weather, to have adequate bedding and a comfortable environment free from drafts. As a producer, you must also spend sufficient time getting calves fully acquainted with feed and watering locations.
Previous rations fed to purchased calves are usually unknown.
It is therefore advisable to offer a very appetizing feed. For the remainder of the feeding period, rations containing Rumensin will control coccidia, enhance feed conversion and reduce the incidence of bloat. Calves must be observed 2 or 3 times per day especially during the first 2 to 3 weeks. Pneumonia is usually the most common problem. Signs of pneumonia will include listlessness, droopy ears, discharges from nostrils, eyes and mouth, increased respiration rate and an elevated temperature.
