Replacement of corn by citrus pulp or coffee hulls explores the potential of dairy cows to digest fiber-rich feedstuffs. However, for the State of Minas Gerais, Brazil, replacing citrus pulp by coffee hulls may reduce milk production costs, since citrus pulp needs to be imported from another state, while coffee hulls are highly available at essentially no cost. The objective of this experiment ...

The aim of this study was to investigate the effects of milking frequency reduction and dietary lipid supplementation on intake, BW, and milk yield and composition in high yielding dairy ewes. Ten lactating Assaf ewes were allocated into 2 experimental groups (n = 5). Ewes were fed alfalfa hay ad libitum and 34 g·kg–1 of BW of a concentrate feed with either 0 (Control group) or 43 g of sunfl ow...

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...
