“…Positive, adverse, and no effects were noted when fermentation products from different pharmaceutical companies were fed. Bartley et al (1953) fed 3 mg of chlortetracycline per 45.4 kg of BW to calves from birth to 42 d and noted a BW gain of 0.78 lb (group 1) and 0.83 lb (group 2) for chlortetracycline-fed calves compared with 0.52 lb/d for control. Chlortetracycline was removed from the diet after 7 wk from calves in group 1 and gain for the next 5 wk was 0.87 lb/d compared with 1.35 and 1.02 for group 2 and control.…”

The first issue of the Journal of Dairy Science in 1917 opened with the text of the speech by Raymond A. Pearson, president of the Iowa State College of Agriculture, at the dedication of the new dairy building at the University of Nebraska (J. Dairy Sci. 1:4-18, 1917). Fittingly, this was the birth of a new research facility and more importantly, the beginning of a new journal devoted to the sciences of milk production and manufacture of products from milk. Metabolic modifiers of dairy cow metabolism enhance, change, or interfere with normal metabolic processes in the ruminant digestive tract or alter postabsorption partitioning of nutrients among body tissues. Papers on metabolic modifiers became more frequent in the journal around 1950. Dairy farming changed radically between 1955 and 1965. Changes in housing and feeding moved more cows outside, and cows and heifers in all stages of lactation, including the dry period, were fed as a single group. Rations became wetter with the shift to corn silage as the major forage in many rations. Liberal grain feeding met the requirements of high-producing cows and increased production per cow but introduced new challenges; for example, managing and feeding cows as a group. These changes led to the introduction of new strategies that identified and expanded the use of metabolic modifiers. Research was directed at characterizing the new problems for the dairy cow created by group feeding. Metabolic modifiers went beyond feeding the cow and included environmental and housing factors and additives to reduce the incidence and severity of many new conditions and pathologies. New collaborations began among dairy cattle specialties that broadened our understanding of the workings of the cow. The Journal of Dairy Science then and now plays an enormously important role in dissemination of the findings of dairy scientists worldwide that address existing and new technologies.

“…The first indication that the response to aureomycin might vary according to the environmental conditions under which calves were kept, came from Bartley and his collaborators. Bartley, Fountaine, Atkeson & Fryer (1953), in an experiment conducted in a calfhouse that had previously proved unfavourable for calf rearing, obtained at 12 weeks an increase in weight of 228 yo over the initial weight for calves receiving 15 mg aureomycin/roo lb. live weight as Aurofac, whereas the controls showed only 190% increase at this time.…”

The Nutritive Value of Colostrum for the Calf

“…A number of workers (4, 8, 77, 32, 36, 40, 44, 53, 54, 60) have drawn attention to the reduced incidence and/or severity of diarrhea or the greater firmness of feces of antibiotic-fed calves as compared to that of controls. A striking example of the effectiveness of Aureomycin (15 mg. per 100 pounds of body weight daily) in the control of common calfhood digestive and respiratory ailments is illustrated by the work of Bartley et al (4).…”

“…The quarters used to house the calves employed in their experiment (4) were not considered to be satisfactory because scours and colds were prevalent and death rates were high in calves previously housed there. Despite this history and the fact that the control calves used in their experiment (4) were affected by colds and scours, Aureomycin supplementation largely prevented these disturbances. The existing evidence indicates that the feeding of Terramycin or Aureomycin tends to help control infectious calfhcod diseases, but they do not afford complete protection from slovenly husbandry practices.…”

“…And Nutrient Utilization or the ration of calves has been found to stimulate the appetite (4,5,8,24,29,36,44,54,60,67,65), whereas penicillin depressed the consumption of feed (37,33,67). Since, in the experiments reviewed, the amounts of milk fed were generally restricted so that the intakes of control and supplemented calves were the same, appetite was expressed in the consumption of hay and concentrates.…”
