The trajectory of the success for a dairy cow begins with mammary development, long before lactation begins.  Dr. Benjamin Enger, Associate Professor for The Ohio State University in Wooster, has worked with his team for years to best understand how infection can change the development and if the timing of infection impacts that response.He was specifically interested in Staphylococcus aureus (SA), a common contagious pathogen in dairy farms. To study this, 21 bred heifers at three stages (6.5, 7.5 and 8.5 months) of pregnancy were inoculated, and tissue samples were collected 21 days later to determine the damage done.In this edition, there is much discussion about the physiology of mammary gland development and how different stages of pregnancy impacts progress towards lactation. Understanding the development of the mammary, will likely illuminate the importance of seemingly meniscal management steps. Analyzing your farm’s data could hold the key to eliminating what might be the source of this devastating pathogen.Listen in today to learn more!Topics of discussionFeatured Articles:Impact of Staphylococcus aureus intramammary infection on cellular proliferation and apoptosis on developing mammary glands of pregnant dairy heifersSupporting article:Impact of intramammary infections on mammary gland development in pregnant dairy heifers during late gestation#2xAg2030; #journalofdairyscience; #openaccess; #MODAIRY; #SA; #staphaureus ; #SA; #mammary; #mammarydevelopment; #heifer; #milk; #dairysciencedigest; #ReaganBluel
