The challenge of preventing major chronic diseases requires reliable, early biomarkers. Gestational mild undernutrition in rats is enough to program the offspring to develop later pathologies; the intake of leptin, a breastmilk component, during lactation may reverse these programming effects. We used these models to identify, in peripheral blood mononuclear cells (PBMCs), transcriptomic-based ...

This study was conducted to compare three models: two random regression models with and without considering heterogeneity in the residual variances and a lactation model (LM) for evaluating the genetic ability of Holstein cows in Korea. Two datasets were prepared for this study. To apply the test-day random regression model, 94,390 test-day records were prepared from 15,263 cows. The second dat...

The objective of the present study was to compare the ability of chlorhexidine and povidone-iodine to cause cessation of lactation in Staphylococcus aureus-infected mammary quarters, assess milk production in the treated quarter in the subsequent lactation, and evaluate whether microbiological cure was obtained. Fourteen mid- to late-lactation Holstein-Friesian dairy cattle from the Washington ...

Three-hour milk production measurements determined by machine milking at 3-d intervals throughout a 63-d lactation period were used to describe lactation curves for crossbred ewes lambing at 1 and 2 yr of age and rearing single and twin lambs. Age of ewe, type of rearing, and day of lactation affected (P < 0.05) milk production. Over the 63-d lactation, average daily milk production was 2.56 an...

ABSTRACT Objective To explore the effects of intraoral pressure on colostrum intake. Methods Healthy women with full-term infants were admitted in study after birth. Intraoral was detected before and mothers’ onset lactation by a sensor during breastfeeding session. Colostrum intake measured weighting infant breastfeeding. The confirmed perceptions sudden breast fullness. Results newborns’ peak...

Climate changes lead to rising temperatures during summer periods and dramatic economic losses in dairy production. Modern high-yielding dairy cows experience severe metabolic stress during the transition period between late gestation and early lactation to meet the high energy and nutrient requirements of the fetus or the mammary gland, and additional thermal stress during this time has advers...

ABSTRACT: Regular removal of milk from the mammary gland is critical to maintaining milk secretion. Early studies in rodents demonstrated that changes in milking frequency inß uenced mammary blood ß ow, as well as mammary cell number and activity. Later studies in ruminants conÞ rmed those observations and that the response was regulated locally within the mammary gland. In addition, it was dis...

Regular removal of milk from the mammary gland is critical to maintaining milk secretion. Early studies in rodents demonstrated that changes in milking frequency influenced mammary blood flow, as well as mammary cell number and activity. Later studies in ruminants confirmed those observations and that the response was regulated locally within the mammary gland. In addition, it was discovered th...

The Sam and Ann Barshop Center for Longevity and Aging Studies is a focal point for advanced research designed exclusively to study the genes involved in aging and the diseases of aging. The research performed at the Barshop Center is based on a solid foundation of nearly twenty-five years of aging research at The University of Texas Health Science Center at San Antonio. Internationally recogni...
