“…However, results from the present study are nonetheless consistent with others (Kruse, 1970). The lower quantity of colostrum produced by this group of animals is not surprising, given that the total milk yield of first lactation heifers throughout the entire lactation is less than that of cows in later lactations (Horan et al, 2005).…”

“…The lower mean IgG concentration in younger cows is consistent with previous studies (Kruse, 1970;Muller and Ellinger, 1981;Pritchett et al, 1991). The immunoglobulins of bovine serum transferred into colostrum carry a wide array of antibody properties against a multitude of antigens to which the cow has been exposed (Larson et al, 1980); older cows are likely to be exposed to a greater number of pathogenic antigens in their lifetime, which is the likely explanation for the increase in colostral IgG with increasing parity.…”

“…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).…”

“…Although much research has been conducted on the factors associated with colostrum quality in cows, including parity (Pritchett et al, 1991;Gulliksen et al, 2008;Kehoe et al, 2011), breed (Muller and Ellinger, 1981), length of the dry period (Pritchett et al, 1991), time interval from calving to milking (Lomba et al, 1978;Moore et al, 2005;Morin et al, 2010) and volume of colostrum produced (Kruse, 1970;Pritchett et al, 1991), few studies have examined the factors associated with the colostrum quality of cows in seasonal, grass-based systems such as those that exist in Ireland. Moreover, only a limited number of studies have attempted to quantify the relationship between colostral IgG concentration and colostral weight (Pritchett et al, 1991;Guy et al, 1994;Baumrucker et al, 2010).…”

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.

“…However, the factor of most critical importance is the concentration of IgG in colostrum (Pritchett et al, 1991).
