“…Ig absorption was improved when calves were housed with the dam. 98 However, considering that acceptable levels of serum IgG can be achieved without housing the calf with the dam, and given that the latter practice may increase the calf's risk of exposure to pathogens in the dam's environment, it is currently recommended that the calf be removed from the dam within 1 to 2 hours of birth and hand-fed colostrum. 3…”

“…It has been reported that efficiency of Ig absorption was improved when calves were housed with the dam [69]. Considering that acceptable levels of serum IgG can be achieved without housing the calf with the dam, however, and given that the latter practice may increase the calf's risk for exposure to pathogens from the dam or her environment, it is currently recommended that the calf be removed from the dam within 1 to 2 hours of birth and then hand-fed a known volume of colostrum [6].…”

Colostrum management is the single most important management factor in determining calf health and survival. Unfortunately, a significant proportion of North American dairy calves suffer from failure of passive transfer of antibodies from colostrum, contributing to excessively high preweaning mortality rates and other short- and long-term losses associated with animal health, welfare, and productivity. A successful colostrum management program requires producers to consistently provide calves with a sufficient volume of clean, high-quality colostrum within the first few hours of life. This article reviews the process of colostrogenesis and discusses important components of colostrum. The key components of delivering and monitoring a successful colostrum management program are discussed.

“…Closure of the calf's intestine to absorption of immunoglobulins begins soon after birth, and increases rapidly after 12 h (Selman, 1973;Stott et al, 1979). Suckled calves have been shown to absorb immunoglobulins more efficiently than calves removed from their dams and handfed (Selman et al, 1971b;Stott et al, 1979). This has been related to the presence of the dam per se (Selman et al, 1971b;Selman, 1973) and/or to a specific suckling effect (Fallon, 1979;Stott et al, 1979).…”

Finally, low calf serum immunoglobulin levels have been related to both higher morbidity and mortality by a number of authors (Hurvell and Fey, 1970;Selman et al, 1971a;Boyd, 1972;Irwin, 1974;Fallon, 1979).…”

Med., Associations between heifer calf management and morbidity, particularly scours and pneumonia, were studied on 104 randomly selected Holstein dairy farms in southwestern Ontario between October 1980 and July 1983. At the farm level, data were stratified by season, with two six-month seasons (winter and summer) per year. The odds of farms with particular management strategies having above median morbidity were calculated. At the individual calf level, the odds of a calf being treated, controlling for farm of origin and month of birth, were calculated for different management practices.Farm size, and policies related to anti-scour vaccination, offering free-choice water and minerals to calves, methods of feeding, and the use of medicated feeds significantly altered the odds of a farm experiencing above-median pneumonia rates. Farm policies with regard to anti-scour vaccination, offering free-choice salt to calves, age at teat removal, type of calf housing, and use of preventive antimicrobials significantly altered the odds of a farm experiencing above-median scours rates.Scours and pneumonia were significantly associated with each other at both the farm and the calf level. No significant associations were found between individual calf management practices and the odds of being treated for scours. Sire used, method of first colostrum feeding, navel treatment, use of anti-scour vaccine in the dam, and the administration of preventive antimicrobials significantly altered the odds of a calf being treated for pneumonia.
