Evaluation of management, nutrient consistency and sanitation of automated calf feeders


The objective of this study was to evaluate management, sanitation and consistency of liquid diets delivered to calves via autofeeders. Ten herds in Virginia and North Carolina with sophisticated(Förster- Technik, Germany) and basic (Biotic Industries, TN) machines were asked a 60-question survey concerning calf and autofeeder management. Duplicate milk replacer samples were obtained to measure standard plate count (SPC), Brix refractometer value and temperature of liquid diet delivered by the autofeeder at the time of the survey.

Nationwide evaluation of quality and composition of colostrum on dairy farms in the United States


The objective of this study was to characterize the quality of maternal colostrum (MC) fed to newborn dairy calves in the United States and identify the proportion of MC that meets industry standards for IgG concentration and total plate count (TPC). Samples of MC (n = 827) were collected from 67 farms in 12 states between June and October 2010. Samples were collected from Holsteins (n = 494), Jerseys (n = 87), crossbred (n = 7), and unidentified dairy cattle (n = 239) from first (n = 49), second (n = 174), third or greater (n = 128), and unknown (n = 476) lactations.

Estimate of colostral immunoglobulin G concentration using refractometry without or with caprylic acid fractionation


Our objectives were to evaluate the use of refractometry as a means of estimating immunoglobulin G (IgG) concentration of bovine maternal colostrum (MC) and determine if fractionation of MC using caprylic acid (CA) improved estimates of IgG. Samples (n = 85) of MC were collected from a single dairy in California and used to determine the method of CA fraction that produced the best prediction of IgG based on CA fractionation followed by refractometry.

Real Raw Milk Facts (Website)


What are the real benefits and risks of drinking raw milk?

A group of scientists gathered together and compiled the best available information about raw milk to provide consumers with a better understanding of key health and safety issues associated with the consumption of unpasteurized dairy products.

Pasteurizing Milk and Colostrum (English & Spanish)


Professional heifer growers and dairy producers are faced with the challenge of raising healthy calves while still paying close attention to rearing costs and profit. Factors that may be considered in selecting a liquid feeding program may include the number of calves fed, economics and cash flow, nutritional characteristics, calf performance targets, resource availability -- for example, consistent supply of non-saleable milk -- infectious disease control concerns, and personal preferences.

The Latest on Colostrum Pasteurization


Recent research studies have shown that the immunity benefits of colostrum can be altered by high bacteria counts. Thus, pasteurizing colostrum with now widely available on-farm pasteurization systems seemed a logical solution to preserving the quality and value of colostrum.

Pasteurization Does Not Degrade Milk (Graph)


Raw-milk advocates believe that pasteurization degrades the healthful benefits of milk, but research has proven otherwise.

Raw milk: playing with fire


U.S. citizens enjoy one of the most abundant and safe food supplies in the world. Along with that abundance and affordability comes a lot of choices, and though it’s still a small subset of the population, an increasing number of people are jumping on the raw-milk bandwagon. Proponents advocate that raw milk has more healthy proteins than pasteurized milk, tastes better, is fresher and does not to contribute to a host of diseases (from diarrhea to autism) that they claim pasteurized milk does.

Pasteurization does not harm milk components


The reports of illnesses related to the consumption of raw milk are increasing on an almost daily basis. In Boone County, Mo., this month, several people, including children, have developed E. coli infections from consumption of raw milk from the same farm.

Investigación muestra que animales de primera lactancia se benefician de haber sido alimentados con leche entera en la crianza


En un estudio publicado recientemente se mostró que novillas alimentadas con leche entera antes del destete produjeron más leche durante la primera lactancia que las alimentadas con sustituto de leche. Los investigadores israelíes publicaron estos resultados en la edición de junio del Journal of Dairy Science.
