Triennial Lactation Symposium: A local affair: How the mammary gland adapts to changes in milking frequency.
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...
متن کاملMilk yield and mammary growth effects due to increased milking frequency during early lactation.
Increased milking frequency (IMF) at the beginning of lactation has been shown to increase milk yield not only during IMF but also after its cessation. The objectives of this experiment evaluated the effects of increased milking frequency initiated during early lactation on mammary growth and effects on milk yield (MY). Thirty-one cows were divided into treatment groups: 1) 2X: cows milked twic...

متن کاملEffect of Milking Frequency on the Lactation Performance and Lactation Curve of Holstein Dairy Cows in Iran
The aim of this study was to investigate the effect of milking frequency (three times daily vs. two times daily) on the lactation curve shape, partial and 305-d lactation performance in Holstein dairy cows in Iran. Data from February 2000 to December 2012 comprising 217345 lactations on 141364 cows distributed in 324 herds collected by the Animal Breeding Center of Iran were used. The mean milk...
متن کاملTriacylglycerol synthesis in goat mammary gland
1. ATP alone had no effect on incorporation of fatty acids synthesized de novo and membrane-bound diacylglycerol into triacylglycerol. Combined addition ofATP and Mg2+ totally inhibits incorporation of fatty acids synthesized de novo and stimulated incorporation of membrane-bound diacylglycerol. 2. ATP, Mg2' and glycerol 3phosphate stimulate incorporation of fatty acids synthesized de novo into...
