Background and Aim: Colostrum pasteurization is an established procedure in dairy farms in developed countries. This practice can improve the health status of the offspring by reducing several pathogens. This study aimed to focus on the pasteurization of bovine first colostrum and its influence on certain important bioactive components. Materials and Methods: This study was conducted in Holstein-Friesian bull calves, which were randomly divided into two groups and fed with 6 L of untreated (UT, n=10) or 6 L of heat-treated (HT, 63.5°C for 30 min, n=10) colostrum from their own dam within the first 12 h after birth. Blood samples were taken before, 24 h, and 48 h after first colostrum intake to determine the concentrations of immunoglobulin G (IgG) and iron and the activity of gamma-glutamyltransferase (GGT) in the serum. Results: The level of IgG was not affected by pasteurization (p=0.19). However, a slower increase in GGT activity (p<0.05) and a lower serum iron concentration (p=0.04) were observed in the HT group. Conclusion: It can be concluded that pasteurization influences the absorption of colostrum components and therefore, the passive transfer of immunity, although the level of IgG was not affected by pasteurization in this study.

Count Reference

Platelet and leukocyte count reference intervals (RIs) for cattle differ by age and while adult RIs are known, RIs for calves are studied less. The aims of this observational study are to evaluate variation of platelet counts of Holstein Friesian calves over the first 14 days of life and to propose RIs for platelet and leukocyte counts of Holstein Friesian calves aged 0–60 days. In a longitudinal study, 19 calves were blood sampled 17 times, in the first 14 days of their lives. Blood was collected in a citrate blood tube and platelet counts were determined. We assessed the course of platelet counts. In a field study, 457 healthy calves were blood sampled once. Blood was collected in an EDTA blood tube and platelet and leukocyte counts were determined. The RIs were calculated by the 2.5 and 97.5 percentiles. Platelet counts started to increase 24 h after birth (mean platelet count 381 × 109/L ± 138 × 109/L) and stabilized after five days (mean platelet count 642 × 109/L ± 265 × 109/L). In calves up to six days of age, platelet counts were lower than in calves older than five days. In conclusion, the RIs of platelet and leukocyte counts in calves were wider in range than the RIs for adult cattle, therefore, calf specific RIs for platelet and leukocyte counts should be used. From 6 until 60 days of age, we propose an RI for platelet counts of 287–1372 × 109/L and for the first 60 days of life an RI for leukocyte counts of 4.0–18.9 × 109/L.

Milk Feeding

The results of feeding experiments, involving a total of 117 Holstein-Friesian calves, were reported. No whole milk nor fresh skimmilk was fed to the calves after their second day of age. Milk substitutes containing 40 to 50 per cent dried skimmilk, 5 to 10 per cent emulsified, stabilized lard and at least 30 p.p.m. of Aureomycin (chlortetracycline) or Terramycin (oxytetracycline) in the dry matter permitted weight gains equal to, or exceeding, the Beltsville standards during the milk feeding period. Supplementary lecithin had no effect on performance of the calves. Weaning calves from milk substitutes at weights of 145 to 150 lb. was considered preferable to weaning at specified ages because of apparent differences in physiological development that exist among calves for the first few months of life.

And Performance

Abstract Immunoglobulins (Ig) are essential components in the colostrum of bovine species that enable passive immunization of newborn calves. Concentrations of fat and protein are greater in colostrum compared with mature milk and represent a vital source of energy and nutrients. Colostral IgG was shown to vary between individual dairy cows, but comparative data on different breeds and performance levels are scarce. The objective of the present field study was to investigate the contents of total IgG, fat, protein, and lactose in colostrum in different Swiss and German dairy and dual-purpose breeds. We collected colostrum samples of 458 cows of 13 different breeds (dairy breeds: Brown Swiss, Swiss and German Holstein Friesian, and New Zealand Holstein; dual-purpose breeds: German Fleckvieh, Holstein Friesian × Montbéliarde, Montbéliarde, Murnau-Werdenfels, Original Braunvieh, Pinzgauer, Rhetic Gray, and Simmental; and beef-type crossbred: Charolais × Holstein Friesian). Colostrum samples were obtained between 5 and 900 min after calving and analyzed for total IgG, fat protein, and lactose contents. Immunoglobulin G concentrations varied between 12.7 and 204.0 mg/mL. No effect of breeding purpose (i.e., dairy or dual-purpose) nor of previous lactation yield on IgG content was observed. However, milking of cows for the first time later than 12 h after parturition resulted in lower colostrum IgG concentrations compared with colostrum harvest within 9 h after calving (P &lt; 0.05). Multiparous cows had a higher colostral IgG concentration than primiparous cows (P &lt; 0.0001). Overall, concentrations of IgG and other constituents in colostrum varied widely in the different cattle breeds. High-yielding dairy cows did not have poorer colostrum quality compared with lower-yielding animals or beef and dual-purpose breeds, which suggests an individually different transfer of circulating IgG into colostrum.

Production Characteristics

With the current situation of low profitability in the beef industry, producers must aim to produce beef efficiently and at minimum cost. In view of the ready availability of Holstein Friesian bull calves as a by-product of the dairy industry, the rearing and finishing of these animals offers a possible source of income to beef producers. The objective of the present study was to examine the influence of slaughter weight on feed efficiency and production characteristics of Holstein-Friesian bulls offered a cereal-based diet.

Carcass Conformation

The continuing trend for increased use of Holstein genetics in dairy herds has resulted in a large number of Holstein-Friesian bull calves becoming available, at low cost, as a potential resource for the beef industry. However, whilst these calves have been bred for dairy traits, which are negatively correlated to many important beef traits (e.g. carcass conformation), it is important to determine the potential yield of boned out joints from these animals, in order to facilitate an assessment of commercial carcass value. The objective of the present study was to evaluate the effect of slaughter weight on yield of boned out joints from Holstein-Friesian bulls and steers offered a cereal-based diet.
