Lactation Stage-Dependency of the Sow Milk Microbiota [PDF]

Frontiers in Microbiology, 2018
Breast milk is essential for the initial development of neonatal animals, as it provides not only essential nutrients and a broad range of bioactive compounds but also commensal bacteria. The milk microbiota contributes to the "initial" intestinal microbiota of infants and also plays a crucial role in modulating and influencing neonatal health. However,

Effect of parity and stage of lactation on feed sorting behavior of lactating dairy cows [PDF]

Journal of Dairy Science, 2011
The objectives of this study were to determine if feed sorting differs between primiparous (PP) and multiparous (MP) cows, if sorting changes from the period of peak lactation to peak dry matter intake (DMI), and whether feed sorting affects efficiency of production. Data on DMI, milk production, feed sorting (particle size of offered and refused feed),

Lysine Metabolism by the Mammary Gland of Lactating Goats at Two Stages of Lactation

Journal of Dairy Science, 2000
An arteriovenous kinetics technique was used to monitor mammary gland lysine and protein metabolism in goats (n = 4) at two stages of lactation (80 +/- 17 vs. 233 +/- 14 DIM) in response to an i.v. infusion of lysine (Lys) plus methionine (Met). At each stage of lactation [2-15N] and [1-13C; 6,6-2H2] Lys kinetics were performed on the last day of 5-d i.

Blood Lipids of Cows at Different Stages of Lactation

Journal of Dairy Science, 1968
Abstract The levels and uptake by the mammary gland of blood lipid components, acetate, ketone bodies, and glucose during early or late lactation were compared to the values during the dry period. During the dry period, levels of plasma phospholipids, cholesterol esters, and free cholesterol dropped to 38.0, 51.7, and 63.9%, respectively, whereas ...
