Evaluation of the effects of oral colostrum supplementation during the first fourteen days on the health and performance of preweaned calves


Although ensuring that calves have APT is the most significant management factor to ensure the health of neonatal calves on calf ranches, colostrum supplementation during the first 2 wk of life in calves was effective in reducing diarrheal disease and the use of antimicrobials. The ADG up to 4 wk of age in colostrum-supplemented calves was significantly greater compared with that in control calves, likely because of a combination of greater energy intake through the liquid feed, increased grain intake, and fewer days with diarrhea.

Pasteurization of Non-Saleable Milk


A review of important considerations of implementing an on-farm pasteurization system and discussion of available research findings related to feeding pasteurized non-saleable milk to calves. Topics include quality of waste milk, precautions for feeding raw milk, heat pasteurization systems, and UV light treatment.

Heat-Treated (in single aliquot or batch) colostrum outperforms non-heat-treated colostrum in terms of quality and transfer of immunoglobulin G in neonatal Jersey calves


Heat-treating colostrum at 60°C for 60 min, using either the Perfect Udder bag or batch pasteurizer system, resulted in a significant reduction of colostrum bacterial counts while maintaining colostrum IgG concentrations compared with fresh frozen or fresh refrigerated colostrum. Calves fed heat-treated colostrum (PU or DTB) experienced significantly improved AEA and higher final serum IgG and STP measures at 24 h of age compared with calves fed fresh (FF or FR) colostrum.

Factors affecting immunoglobulin concentration in colostrum of healthy Holstein Cows immediately after delivery.


This study analyzed the influence of the number of milkings, number of births, and udder quarter in immunoglobulin (Ig) concentration in the colostrum of healthy Holstein cows. It was collected two samples of colostrum by manual milking, getting the first jets to completion of bacteriological examination and immunoglobulin levels by radial immunodiffusion test in agar gel. Immunoglobulin concentrations in the colostrum of Holstein cows were influenced by the number of milking after delivery and the number of lactations. These variations may reduce the immunological quality of

Fatores que afetam o nível de imunoglobulina no colostro de vacas Holandesas sadias imediatamente apos o parto


A pesquisa avaliou a inluência do número de ordenhas, número de parições e quarto mamário na concentração de imunoglobulinas (Ig) do colostro de vacas hígidas da raça Holandesa. Foram colhidas duas amostras de colostro por ordenha manual, obtendo-se os de imunodifusão em gel de ágar. As amostras positivas ao exame bacteriológico foram eliminadas desta investigação.

Reducing Failure of Passive Immunoglobulin Transfer in Dairy Calves


The dairy calf is unique in that its only source of early immunity is obtained passively from colostrum after birth. There are many factors that impact the early immune status of the dairy calf. Primary factors include the quality of colostrum fed, time of feeding and amount fed. The resulting condition when blood IgG levels are not met is termed failure of passive transfer or FPT.

Feeding Colostrum with an Esophageal Feeder Does Not Reduce Immunoglobulin G absorbtion in Neonatal Dairy Heifer Calves


Newborn Heifer calves were studied to compare total serum protein and IgG concentrations and apparent efficiency of absorbtion when colostrum was fed by nipple bottle or esophageal feeder. All calves recieved a total dose of 285 g of IgG. The results showed no differences between treatments when examining IgG concentration, total serum protein concentration or AEA and all treatments provided successful passive transfer of immunity.  These results confirm that esophogeal feeders can be used to administer up to 3.8 L of colostrum to newborn calves.

Guidelines for young stock


General Guidelines
ALL animals must have shelter from the wind and be able to use the shelter at the same time- This may be a wind block, trees, or an enclosure for mature animals. 

Increase food availability - animals are spending a lot of energy staying warm.

Make sure fresh water is available to all animals.  Snow is not a water source for animals.

Pasteurizing colostrum: the next step to controlling disease


Calves Absorbed MORE immunoglobulins When Colostrum was Pastuerized.

Chilling Fast is Cool for Colostrum, Not Bacteria


FEEDING colostrum to newborn calves is a well-known requirement to those raising healthy calves. And it’s not only about quantity but quality. In addition to protein and immunoglobulin content as a measure of colostrum quality, cleanliness of colostrum is important, too. High levels of bacteria in colostrum reduce the calf’s ability to absorb the colostrum. Also, bacteria in colostrum can be the starting point for infection.
