Blood Lipids of Cows at Different Stages of Lactation
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 ...

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

Dynamics of changes in some selected components of sheep milk in the course of lactation
The objective of our study was to evaluate dynamics of changes in contents of some components of sheep milk, viz. dry matter (DM), fat (F), true protein (TP), casein (C), whey protein (WP) and lactose (L).

Endocrine changes in sows weaned at two stages of lactation [PDF]
Plasma concentrations of LH, FSH, prolactin, oestradiol-17 beta and progesterone were determined in 18 multiparous sows at 4-h intervals for 15-18 days around weaning at 3 or 5 weeks post partum. Sampling at 10-min intervals for 6 h occurred every 2 days throughout the same period.
