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

Extract: 

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

Extract: 

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

Extract: 

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

Extract: 

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

Extract: 

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

Extract: 

by Jud Heinrichs and Coleen Jones
The authors are a professor and research associate in the department of
dairy and animal science at Penn State.
Calves absorbed more immunoglobulins when colostrum was pastuerized.
Pasteurization has been shown to be very effective at killing a variety
of pathogenic bacteria including: Salmonella, E. coli, Mycobacterium
avium subspecies paratuberculosis, Mycobacterium californicum,
Mycobacterium bovis, and Listeria monocytogenes. With proper

Chilling Fast is Cool for Colostrum, Not Bacteria

Extract: 

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.

Heat-treated colostrum and reduced morbidity in preweaned dairy calves: Results of a randomized trial and examination of mechanisms of effectiveness

Extract: 

A randomized controlled clinical trial was conducted using 1,071 newborn calves from 6 commercial dairy farms in Minnesota and Wisconsin, with the primary objective being to describe the effects of feeding heat-treated colostrum on serum immunoglobulin G concentration and health in the preweaning period. A secondary objective was to complete a path analysis to identify intermediate factors that may explain how feeding heat-treated colostrum reduced the risk for illness.

Raw milk linked to most dairy-related disease outbreaks

Extract: 

The rate of outbreaks caused by raw, unpasteurized milk and products made from it was 150 times greater than outbreaks linked to pasteurized milk, according to a study by the Centers for Disease Control and Prevention.
