Canine colostrum milk (CCM) is a specific secretion of the mammary gland that is fundamental for the survival of the newborn. CCM has many described components (immunoglobulins, proteins or fat), but its small vesicles, named exosomes, are largely unknown.

The mammary gland is a unique organ for milk synthesis, secretion and storage, and it undergoes cyclical processes of development, differentiation, lactation and degeneration. At different developmental periods, the biological processes governing mammary gland physiology and internal environmental homeostasis depend on a complex network of genes and regulatory factors.

A four years age cow was presented to the Veterinary Clinical Complex (VCC), College of Veterinary Science, Rajendranagar, Hyderabad with the history of decreased appetite, depression, decreased milk yield and with swollen mammary gland for four days. General clinical examination revealed increased body temperature of 1040 F and palpation of udder revealed swollen udder and animal is feeling pain on touch. Milk was stripped for testing and found flakes and the colour of the milk is yellowish brown.

Provision of nutrients in balanced form and required amount is crucial to meet the productive targets in dairy cows. Among the various nutrients, protein is the most important nutrient for milk production. Methionine and lysine are considered as the first and second limiting amino acids for milk protein synthesis because of their low concentrations in feed protein as compared to their concentrations in milk and ruminally synthesized bacterial protein. Choline, a component of phospholipid and methyl donor, plays an essential role in biosynthesis and secretion of milk.

MFG-E8 (milk fat globule-EGF factor 8) is a peripheral membrane glycoprotein, which is expressed abundantly in lactating mammary glands and is secreted in association with fat globules. This protein consists of two-repeated EGF-like domains, a mucin-like domain and two-repeated discoidinlike domains (C-domains), and contains an integrin-binding motif (RGD sequence) in the EGF-like domain. To clarify the role of each domain on the peripheral association with the cell membrane, several domain-deletion mutants of MFG-E8 were expressed in COS-7 cells. ...

Lactoferrin (LF) is a Fe 3+ -binding glycoprotein, first recognized in milk and then in other human epithelial secretions and barrier fluids. Many different functions have been attributed to LF, including protection from iron-induced lipid peroxidation, immunomodulation and cell growthregulation, DNA binding, and transcriptional acti-vation. Its physiological role is still unclear, but it has been suggested to be responsible for primary defense against microbial and viral infection.

Success in dairy farming depends largely upon the proper feeding of stock. There are two questions that the dairy farmer should always ask himself: Am I feeding as cheaply as I can? and, Am I feeding the best rations for milk and butter production? Of course cows can be kept alive and in fairly good milk flow on many different kinds of food, but in feeding, as in everything else, there is an ideal to be sought. What, then, is an ideal ration for a dairy cow? Before trying to answer this question the word ration needs to be...

Milk evolved as a means of providing for the postnatal needs of the developing mammalian neonate. Any perception that milk is a simple, homogeneous fluid does not adequately acknowledge the remarkable array of complex activities and functionalities of its constituent components.

All female mammals nurse their young with milk, which is secreted from special glands, the mammary glands. According to Mammal Species of the World, 5,702 species were known in 2005. These were grouped in 1,229 genera, 153 families and 29 orders.[1] In 2008 the IUCN completed a five-year, 17,000-scientist Global Mammal Assessment for its IUCN Red List, which counted 5488 accepted species at the end of that period.
