Evaluation of the Brix refractometer as an on-farm tool for the detection of passive transfer of immunity in dairy calves. 2011. J. Med. Res. Both of these tools are designed to prevent failure of passive transfer by ensuring that the colostrum fed is high quality (> 50 mg IgG/mL) and are described in other articles on this site. Colostrum supplements can be used to increase the amount of IgG fed to calves when only low or medium quality colostrum is available. Assoc. Serum immunoglobulin G concentrations in calves fed fresh colostrum or a colostrum supplement. Dairy Sci. If more than 10% of calves are experiencing failure of passive transfer, then it is likely that some element of colostrum management may need improvement to ensure that each calf receives and adequate quantity of clean, high-quality colostrum within a few hours of birth. When available colostrum is low in quality, producers have several options using stored colostrum and products formulated to supplement or replace colostrum. For example, fat content ranges from 6 to 25%. collaborators. Another part of this project evaluated the risk of calves becoming infected with Mycobacterium avium subsp paratuberculosis (Pithua et al., 2009) and found calves fed colostrum replacer at birth were less likely to be infected than those fed colostrum. J. The Department of Animal Science is home to teaching, research, and extension programs … North Am. Aust.

The efficiency of antibody absorption in calves decreases with time after birth, thus the sooner a calf receives colostrum the better. Dairy Sci. These products are made from bovine colostrum or serum and contain 100 to 150 g of IgG per dose. Prior to measuring the total protein or %Brix, be sure that the refractometer is calibrated (the horizontal line should be at the zero mark when a drop of water is placed on the refractometer surface). 221:1605-1608. Supplement products (fed in addition to colostrum) provided 136 g of IgG with 19% absorption efficiency and resulted in serum IgG of 9 mg/mL. Evaluation of digital and optical refractometers for assessing failure of transfer of passive immunity in dairy calves. Providing colostrum to calves is vital for ensuring health and protection from disease during the first weeks of life. Wells, and M. J. Oakes. Apparent efficiency of IgG absorption was not different in CON and FFE as calculated using the Penn State colostrum calculator spreadsheet (Jones and Heinrichs, 2016). Penn State College of Agricultural Sciences research, extension, and resident education programs are funded in part by Pennsylvania counties, the Commonwealth of Pennsylvania, and the U.S. Department of Agriculture. Colostrum products can be valuable tools to increase calf immunity. Assoc. As mentioned previously, the amount of protein in the calf's intestine can also influence the absorption of IgG. 16:187-191. Multiple trials have reported acceptable levels of serum IgG and total protein in calves fed various replacer products (see table below). Gratitude is also expressed to the Penn State Food Science Department especially Emily Furumoto and Byron Ba for their assistance in colostrum processing. Feed Sci. Dairy Sci. Am. A special appreciation goes to the faculty and staff of the Penn State Animal Science Department for sharing their The absorption efficiency of calves can be calculated on-farm to determine whether the different factors involved in colostrum feeding are working efficiently. This result, the total grams of IgG in the blood, is then divided by the total amount of IgG fed, which can be estimated using a colostrometer for colostrum or found on the label of colostrum supplement or replacer products. Feeding colostrum late or not at all and feeding poor quality colostrum are primary causes of FPT in calves. Research from Penn State reported calves absorbed more IgG from pasteurized colostrum than from colostrum not pasteurized. Med. J. Colostrum replacer contains greater levels of IgG and other nutrients and provides an effective, convenient method of providing passive immunity to calves when maternal colostrum is not available. 2010. DAS 11-180 Colostrum Supplements and Replacer 6 Visit Penn State… Review of recent research investigating effects of calf feeding program on first lactation performance. Colostrum was collected from The Pennsylvania State University dairy herd and divided by quality (high, medium, or low) based on colostrometer measurements. Vet. Failure of passive transfer (FPT) in dairy calves is defined as a blood IgG level of less than 10 mg/mL at 24 to 48 hours after birth. This absorption efficiency is very good when we consider that research data suggests maximum absorption efficiencies of around 35% for maternal colostrum. However, a study using a wide variety of colostrum samples conducted at Penn State and published in the Journal of Dairy Science early this year showed that, on average, heating colostrum at 140°F for 30 minutes is the optimum combination to reduce bacteria counts without affecting colostrum IgG … Santoro, H. M., P. S. Erickson, N. L. Whitehouse, A. M. McLaughlin, C. G. Schwab, and J. D. Quigley, III. Get notified when we have news, courses, or events of interest to you. Calves absorbed more immunoglobulins when colostrum was pastuerized. 76:831-836. Time of the first colostrum feeding is the most critical factor affecting absorption efficiency, and calf care personnel need to do everything they can to feed colostrum or colostrum products as soon as possible after birth. All calves should receive colostrum within 2 to 4 hours of birth. Quigley, J. D., III, C. J. Kost, and T. M. Wolfe. 34:31-46. J.

Colostrum supplements can be used to increase the amount of IgG fed to calves when no source of quality colostrum is available, but supplements cannot replace high quality colostrum. Comparison of refractometers and test endpoints in the measurement of serum protein concentration to assess passive transfer status in calves. 2010. Holloway, N. M., J. W. Tyler, J. Lakritz, S. L. Carlson, R. K. Tessman, and J. Holle. Clin. Serum IgG and total protein concentrations in dairy calves fed two colostrum replacement products. We can measure how well a colostrum program is working by estimating the IgG in calves' blood. Supplement products are less expensive than replacer products, but they are less convenient and do not provide a break in the disease transmission cycle because some colostrum must still be fed. If preliminary studies are removed from the summary to provide a better estimate of products currently on the market, replacer products provided an average of 157 g of IgG, with an absorption efficiency of 31%, and serum IgG of 12 mg/mL. Jones, C. M., R. E. James, J. D. Quigley, III, and M. L. McGilliard. Absorption efficiency would be: [(8 g/L IgG x 4.1 L) / 100 g IgG] x 100 = 32.8% AEA. Let's assume the blood IgG concentration tested at 24 hours of age was 8 mg/mL (or g/L) and the calf was fed a total of 100 g of IgG (assuming 2 L of colostrum containing 35 g/L IgG was fed, and due to its poor quality, a supplement was used to provide another 30 g of IgG). 1996.

In other cases, the consistency and convenience of colostrum products is preferred over testing, sorting, and storing maternal colostrum. Each of these refractometers are equally accurate, but be sure to check which scale your refractometer has because the values to indicate successful colostrum management and transfer of immunity are different for each scale. J. Med. 2004. Calves that experience FPT are more likely to become sick or die in the first two months of life than calves with adequate immunity. In an experiment where calves received the same amount of IgG from either colostrum or a serum-based colostrum replacer (Jones et al., 2004), no differences between the calves were observed in IgG levels, efficiency of IgG absorption, incidence of scours, or growth rate during the first month of life. Passive immunoglobulin transfer in newborn calves fed colostrum or spray-dried serum protein alone or as a supplement to colostrum of varying quality. A calf's ability to absorb IgG can be affected by individual factors including difficult birth and other stressors, thus several calves should be tested to provide an accurate assessment of colostrum management.

Dairy Sci. Be sure to read and follow the manufacturer's instructions for feeding; some products are mixed with warm water and fed in an extra feeding, others are added to colostrum, and the number of feedings recommended may vary. J. Colostrum and calf serum Brix readings were similar in feeding groups. Bovine colostrum is a supplement made from a milky fluid that’s released from the udders of cows shortly after they’ve given birth. 10:304-307. Colostrum supplements available today are made from dried bovine colostrum or serum and contain 40 to 60 g of IgG per dose (9 to 13% globulin protein). A special thanks to the Penn State dairy managers and staff for all the support received during my experiments. Polo, A. Lago, J. Campbell, J. Quigley, and H. Tyler. Samples should be collected when the calf is between 2 and 7 days old to provide the most accurate indication of passive transfer (Elizondo-Salazar and Heinrichs, 2009). Unfortunately, not all colostrum is the same. Feeding colostrum late or not at all and being forced to feed poor quality colostrum are primary causes of FPT in calves. Colostrum supplements can be used to increase the amount of IgG fed to calves when only low or medium quality colostrum is available. 1993. $54.99.

The table shows recommended serum total protein and %Brix values from several studies conducted in different regions of the United States and other countries. Written by Sonia Gelsinger, Graduate Student. Dairy Sci. 87:2047-2054. The lowest mortality occurred when serum total protein was 5.5 to 7.0 g/dL. Generally, higher total protein and %Brix values indicate higher concentration of IgG; however, very high values can indicate that a calf is dehydrated. Unfortunately, not all c… Studies published many years ago from Virginia Tech showed that, when bacteria colonized the gut of the calf before colostrum feeding, IgG absorption declined. 2015. Differences in Ig production were evaluated by obtaining Holstein colostrum from 3 commercial dairy herds (689 to 1,862 cows/herd) in central Pennsylvania. 237:949-954. Some refractometers contain a scale that estimates serum total protein in g/dL. That’s double the value for plain whole milk. They do not contain sufficient quantities of antibodies to raise the blood IgG level in calves beyond what average quality colostrum will do. Regardless of the number of feedings required, the full 4 quarts should be consumed within 8 hours of birth. Recent study of colostrum has shown it contains many growth factors and hormones. Effects of colostrum replacer supplemented with lactoferrin on the blood plasma immunoglobulin G concentration an intestinal absorption of xylose in the neonatal calf.
