“…Ensuring that the neonatal calf ingests and absorbs a critical mass of IgG from colostrum is necessary for it to acquire immunity (McGuirk and Collins, 2004) and is established as being crucial to its future health and productivity (Kruse, 1970;Robison et al, 1988;DeNise et al, 1989). The bovine placenta does not allow the transfer of immunoglobulins from the dam to the calf while in utero and so the newborn calf must absorb a critical mass of IgG from colostrum before cessation of intestinal transport occurs at 24 to 36 h of age to acquire immunity against the pathogenic organisms it will encounter as soon as it is born (Weaver et al, 2000).…”

“…Colostrum is the first milk secreted after parturition (Park and Jacobson, 1993) and contains many substances that are important to the health of the neonate including immunoglobulins, cytokines, nutritional elements and growth factors (McGuirk and Collins, 2004). Immunoglobulins are plasma proteins, produced by lymphocytes in the mammalian bloodstream in response to foreign antigens, which play a crucial role in the immune mechanism to defend the body from pathogenic organisms and provide resistance to disease (Park and Jacobson, 1993).…”

“…Although colostrum contains a wide spectrum of other important components, the relationship between IgG concentrations and calf health is best understood; thus, the concentration of IgG in colostrum is considered the hallmark for evaluating colostrum quality (Godden, 2008). Good-quality bovine colostrum is defined as colostrum that has an IgG concentration of .50 g/l (McGuirk and Collins, 2004).…”

Transfer of sufficient immunoglobulin G (IgG) to the neonatal calf via colostrum is vital to provide the calf with immunological protection and resistance against disease. The objective of the present study was to determine the factors associated with both colostral IgG concentration and colostral weight in Irish dairy cows. Fresh colostrum samples were collected from 704 dairy cows of varying breed and parity from four Irish research farms between January and December 2011; colostral weight was recorded and the IgG concentration was determined using an ELISA method. The mean IgG concentration in the colostrum was 112 g/l (s.d. 5 51 g/l) and ranged from 13 to 256 g/l. In total, 96% of the samples in this study contained .50 g/l IgG, which is considered to be indicative of high-quality colostrum. Mean colostral weight was 6.7 kg (s.d. 5 3.6 kg) with a range of 0.1 to 24 kg. Factors associated with both colostral IgG concentration and colostral weight were determined using a fixed effects multiple regression model. Parity, time interval from calving to next milking, month of calving, colostral weight and herd were all independently associated with IgG concentration. IgG concentration decreased ( P , 0.01) by 1.7 (s.e. 5 0.6) g/l per kg increase in the colostral weight. Older parity cows, cows that had a shorter time interval from calving to milking, and cows that calved earlier in spring or in the autumn produced colostrum with higher IgG concentration. Parity ( P , 0.001), time interval from calving to milking ( P , 0.01), weight of the calf at birth ( P , 0.05), colostral IgG concentration ( P , 0.01) and herd were all independently associated with colostral weight at the first milking. Younger parity cows, cows milked earlier post-calving, and cows with lighter calves produced less colostrum. In general, colostrum quality of cows in this study was higher than in many previous studies; possible reasons include use of a relatively low-yielding cow type that produces low weight of colostrum, short calving to colostrum collection interval and grass-based nutritional management. The results of this study indicate that colostral IgG concentration can be maximised by reducing the time interval between calving and collection of colostrum.

Calves represent the future of the dairy and, as such, management during the critical stage from birth to weaning is critical to the development, health, productivity, and profi tability of the future replacement heifers. The perinatal period is one of the most vulnerable times in the life of the calf, and attention to the details of calving and calf viability immediately after birth can prevent the losses commonly encountered in the fi rst 48 h of life. New concepts in colostrum management not only reinforce the importance of colostral immune factors on calf health but also emphasize its longer term impact on intestinal, ruminal, and metabolic development as well as the impact on endocrine status, growth, productivity, and survival. Nutritional management concepts have changed and are now appropriately focused on targeted growth with components and delivery systems that promote welfare, performance, and future production. Whether young calves are housed in individual or group pens, important principles of housing management can be applied to insure the health and welfare of preweaned calves. Routine health maintenance practices, preventive health screening, and effective treatment protocols should be strategically integrated into the management of young calves to optimize health, minimize stress, cost, and the possibility of doing harm.
