“…The observed negative impact of cell level, estimated through SCC, on IgG1 concentration suggested that for efficient immune protection, high-cell-content colostrum should not be used to feed newborn calves (Dardillat et al, 1978), as recommended in many countries. Finally, neither average colostral IgG1 concentration nor colostrum composition were affected by previous performance, in agreement with Robinson et al (2009).…”

High-immune quality colostrum (IgG1 concentration ⩾50 g/l) is crucial for the health and development of the young calf. Studies on colostrum quality tend to focus on external factors such as breed, parity or dry period length, but few have focused on within-cow variations. Here we ran experiments to gain a deeper insight into within-cow variation in IgG1 concentrations in dairy cow colostrum. Trials were performed in an experimental farm, located in the Western part of France. Colostrum from each quarter and a composite sample (mix of four quarters) were concomitantly collected on 77 Holstein dairy cows just after calving to assess the influence of sample type on IgG1 concentrations. Variation in IgG1 concentrations during the first milking was studied on samples from nine cows collected every minute from the start of milking. Repeatability of colostral IgG1 concentration was estimated from 2009 and 2010 data on 16 healthy cows. IgG1 concentrations were tested using a radial immunodiffusion method. Sensitivity and specificity were similar regardless of sample type tested (individual quarter or composite milk). Mean average IgG1 concentration was 54.1 g/l in composite colostrum, and was significantly higher in hind quarter teats (56.2 g/l) than front quarter teats (53.1 g/l). Average IgG1 concentration did not change significantly during colostrum milking, and the variations observed (15% or less) were likely due to the laboratory method (CV 15%). IgG1 concentrations in dam colostrum increased slightly from 2009 to 2010 due to BW and parity effects. In 56% of cases, colostrum quality could have been assessed on either individual or composite colostrum samples collected at any time during the first milking without affecting the reliability of the measurement. However, in other cases, differences were significant enough to mean that estimates of average IgG1 concentration in colostrum from any one quarter would not be reliable. It is concluded that colostrum quality, from an IgG1 concentration point of view, could be assessed with a composite sample taken at any time during the first milking.

“…Colostrum protein concentration was within the normal range (approximately 70 to 230 g/kg; Kehoe et al, 2007) expected for Holstein dairy cows. Likewise, as in previous reports (Tesfa et al, 1999;Santos et al, 2001), no association was found between colostrum composition and precalving diet or cow maturity and no differences in density, as reported by Robinson et al (2009). We noted limited effects of experimental treatment on milk composition over the first 20 wk of lactation.…”

An experiment was designed to study the effect of precalving supplementation with protein (Pr) and rumen-inert fat (F) on body composition and subsequent milk production and composition. Forty Holstein-Friesian dairy cows were allocated to 1 of 4 dietary treatments in the dry period (DP) based on a first-cut ryegrass silage, with 6 mature (in their third or greater pregnancy) and 4 young (in their second pregnancy) cows per treatment. These were low Pr, low F (silage alone); low Pr, high F (silage with 10% rumen-inert fat, mixed on a dry matter basis); high Pr, low F [silage with 5% high-protein corn gluten meal (CGM)]; and high Pr, high F (silage with 5% CGM and 10% rumen-inert fat). All the diets were individually offered ad libitum and dry matter intake (DMI) was recorded daily during the DP. After calving, all cows received ryegrass silage plus 8 kg/d of a commercial dairy concentrate. During the DP, DMI was higher for mature than for young cows. All animals recovered body condition score (0.13 units/wk, 1-5 scale), reaching a maximum score of 2.4 some days before calving. Precalving maximum muscle longissimus dorsi (LD) depth was greater for mature (47.5 mm) than for young cows (45.7 mm), and milk fat concentration was also higher for mature than for young cows (40.2 and 39.0 g/kg, respectively). Supplementation with CGM increased maximum LD depth (from 45.9 to 47.6 mm), calf birth weight (low Pr = 43.2, high Pr = 46.3 kg), and milk crude protein concentration (from 30.8 to 31.6 g/kg). Fat supplementation in the DP of the mature cows increased maximum back fat depth (from 3.6 to 4.5 mm), milk yield (low F = 26.3, high F = 28.7 kg/d), and Pr yields (low F = 837, high F = 899 g/d). Inclusion of F in the DP diets reduced casein concentration in milk at wk 3 of lactation from 26.3 to 24.5 g/kg. Milk CP yield was also increased by CGM supplementation when compared within cows receiving F-supplemented silages (low Pr, high F = 832 g/d; high Pr, high F= 877 g/d). It can be concluded that CGM supplementation in the DP increased subsequent milk Pr concentration, but milk Pr yield increased only in those animals also receiving F supplementation. Dry period diet supplementation with F increased maximum back fat depth and milk and CP yields in the mature cows, and led to more LD muscle mobilization during early lactation. Second-calving cows had a lower DMI and milk fat concentration than mature cows.

“…Comparing the importance of the calving season for the density of colostrum, these authors found the highest density of colostrum for cows calving in winter and the lowest for those calving in spring. The results reported by Robinson et al [2009] and Guliński and Giersz [2006] also indicate the similar effect of cow's age on the density of colostrum.…”

“…This difference was statistically significant at P ≤ 0.01. Robinson et al [2009] showed that the average yield of colostrum in the first milking after calving in the Holstein breed in the United States was 10.6 kg, for primiparous cows, and 13.6 kg, for multiparous cows. In turn, Gavin et al [2018] , who studied Jersey cows in the US in 2016, noted the average colostrum yield ranging between 6.6 kg per cow (in June) and 2.5 kg per cow (in December).…”

“…breed, type and individual characteristics. The length of the dry period, the feeding of pregnant cows, the length of the calving period, the length and meth-ods of drying, and the time elapsed from parturition are also important in terms of the quality of colostrum [Szulc and Zachwieja 1998, Gapper et al 2007, Robinson et al 2009, Wojtas and Zachwieja 2016.…”

The aim of the study was to analyse the concentration of immunoglobulins in colostrum produced by Polish Holstein-Friesian (PHF) cows in relation to selected factors. An important element of the study is the analysis of colostrum yield and density. The research was conducted between April 2017 through April 2018. The yield and selected traits of colostrum obtained from the first 9 milkings from 20 PHF cows calving during this period were analysed. A total of 180 measurements were made. The average immunoglobulin content in the 180 observations was 37.7 g • L -1 , ranging between 7 and 140 g • L -1 . The study showed a significant effect of time after calving on the content of immunoglobulins. The highest content of the antibodies was found in colostrum obtained immediately after calving. Its average level at that time was 90.2 g • L -1 and in 20 assessed cows it ranged within the wide limits of 32-140 g • L -1 . The quality of colostrum radically deteriorated soon after calvong. The lowest level of immunoglobulins was found in the 96th hour after parturition and it was on average 10 g • L -1 . The average yield of colostrum was 10.3 kg. The yield of colostrum increased with time elapsing after calving. The lowest colostrum yield was observed within 2 hours, the highest within 96 hours after calving, respectively, 6.9 and 12.4 kg. The average specific density of colostrum was 1.041 g • cm -3 . The study showed that the highest density was characterized by colostrum obtained in the first milking post-partum. Its specific weight was 1.059 g • cm -3 . In subsequent milkings, the calcareous density of colostrum systematically decreased to 1.030 g • cm -3 in the 90th hour after calving.
