Solutions for the Dairy Industry
Milk is a complex food that contains vital nutrients for the bodies of young mammals. Milk is the only food of the mammal during the first period of its life and the substances in milk provide energy and antibodies that help protect against infection.
The techniques used in the production of milk using cows, goats, sheep and buffaloes began around six thousand years ago. The same species of animals are kept for milking today. The animals used for milk production are ruminants that eat quickly, in great quantities, and later digest their food.
Today, the most widespread milking animal in the world is the cow. The cow can be found on all continents around the world. Other animals commonly used in both subsistence and industrial dairy farming are goats, sheep and buffaloes. The milk of these animals is of great importance to rural communities as a source of high-quality protein and other constituents. Sheep and goats are of exceptional importance in areas such as the Mediterranean and in large areas of Africa and Asia.
The number of sheep and goats in the world is in the billions and they are the most numerous of all milk- and meat-producing animals. The contribution of sheep and goats to milk and meat production in the poorest areas is also considerable: Both animals are a cheap source of food and are mainly kept in conditions where climatic, topographical, economic, technical or sociological factors limit the development of more sophisticated protein production systems.
Among the essential minerals and vitamins in milk are iron and vitamin D. They are, however, not present in sufficient amounts, or in optimum proportions, to fulfil the requirements for complete nutrition.
During the first period of its life, the young animal therefore makes up for the shortage of certain nutrients in milk by exploiting the reserves it receives from its mother at birth, which are normally sufficient until its diet includes other foods. To make the nutrients easily consumable and digestible, they are available in a liquid state, partly as a solution, partly as dispersion or suspension. There is a wide variation in the balance of components in milk from various mammals, although the components themselves are basically the same.
Quantities of the various main constituents of raw milk from cows can vary considerably; between cows of different breeds and between individual cows of the same breed. Water is the principal constituent and it is the carrier of all other components. Zoom Fig 1. Considerable changes have taken place in the genetic makeup of the Bos Taurus species since the cow was taken on as a service animal some six thousand years ago.
The most significant of these is that the modern lactating dairy cow has a much higher milk production than its calf needs. Genetic development has resulted in vastly increased lactation production.
Even around thirty years ago a cow would typically only produce somewhere in the region of 4. Some cows can produce up to Increased knowledge about the importance of herd management, animal well-being and optimized feeding has contributed to this genetic development. As is the case with all mammals, cows produce milk for their offspring. Therefore, the production of milk is closely linked to the reproductive cycle. Before a female cow can start to produce milk she must first have had a calf.
Females reach sexual maturity at the age of seven or eight months and are then called heifers. The gestation period typically lasts days and heifers tend to give birth to their first calves at the age of They are typically bred again four to eight weeks after calving. Each half is divided into quarters by a shallower transverse crease.
Each quarter has one teat with its own separate mammary gland. It is therefore theoretically possible to get milk of four different qualities from the same cow. A sectional view of the udder is shown in Figure 1. The external layer of this tissue is muscular, thus giving cohesion to the body of the udder and protecting it against injury. The glandular tissue contains around two billion tiny bladders called alveoli. The milk-producing cells are located on the inner walls of the alveoli, which occur in groups of Capillaries leading from the alveoli converge into progressively larger milk ducts which lead to a cavity above the teat.
The cistern of the udder has an extension reaching down into the teat; this is called the teat cistern. At the end of the teat there is a channel Between milking, the teat channel is closed by a sphincter muscle which prevents milk from leaking out and bacteria from entering the udder.
The whole udder is laced with blood and lymph vessels. These bring nutrient-rich blood from the heart to the udder, where it is distributed by capillaries surrounding the alveoli.
In this way, the milk-producing cells are furnished with the necessary nutrients for the secretion of milk. Spent blood is carried away by the capillaries to veins and returned to the heart. Large quantities of blood flow through the udder. A cow that produces 60 litres of milk per day will need some As the alveoli secrete milk their internal pressure rises.
If the cow is not milked, secretion of milk stops when the pressure reaches a certain limit. Increase of pressure forces a small quantity of milk out into the larger ducts and down into the cistern. Most of the milk in the udder, however, is contained in the alveoli and the fine capillaries in the alveolar area. These capillaries are so fine that milk cannot flow through them of its own accord. It must be pressed out of the alveoli and through the capillaries into the larger ducts.
Muscle-like cells surrounding each alveolus perform this duty during milking see Figure 1. The cow then continues to give milk for around 10 months approximately days. This period is known as lactation.
At this stage milking is discontinued and the cow has a non-lactating period of up to 60 days prior to calving again. With the birth of the calf a new lactation cycle begins. The udder also contains a lymphatic system. It carries waste products away from the udder. The lymph nodes serve as a filter that destroy foreign substances but also provide a source of lymphocytes to fight infections.
Sometimes, around parturition cows giving birth for the first-time suffer from oedema, partly caused by the presence of milk in the udder which compresses the lymph nodes. Calves are born lacking their own immune protection as their immune system develops slowly. In response, the first milk a cow produces after calving is called colostrum, which differs greatly from normal milk in both composition and nutritional properties.
Calves are dependent on receiving maternal antibodies and an essential supply of immunoglobulins via colostrum. Each individual varies in its ability to produce antibodies and thus fight disease. Animals receiving inadequate colostrum are extremely vulnerable to intestinal infection and subsequent scours. A calf needs around 1. Yield will rise during the first months after calving, followed by a long period of continuous decline. The shape of the lactation curve will differ from individual to individual and from breed to breed.
Feeding and management also influence the shape and have a significant impact on the total amount of milk produced. Lactation is ideally days, but in practice it is usually more, followed by a two-month dry period prior to the next calving. This hormone is secreted and stored in the pituitary gland. When the cow is prepared for milking by the correct stimuli, a signal is sent to the gland, which then releases its store of oxytocin into the bloodstream.
The oxytocin was released when the cow feels the calf sucking. The oxytocin hormone begins to take effect about a minute after preparation has begun and causes the muscle-like cells to compress the alveoli. This generates pressure in the udder and can be felt with the hand; it is known as the let-down reflex. The pressure forces the milk down into the teat cistern, from which it is sucked into the teat cup of a milking machine or pressed out by the fingers during hand milking.
The effect of the let-down reflex gradually fades away as the oxytocin is diluted and decomposed in the bloodstream, disappearing after minutes. Milking should therefore be completed within this period of time. Milk fat consists mainly of triglycerides, which are synthesized from glyceroles and fatty acids. Long-chained fatty acids are absorbed from the blood. Short chained fatty acids are synthesized in the mammary gland from the components acetate and beta hydroxybutyrate which have their origins in the blood.
Milk protein is synthesized from amino acids also with origin from the blood and consists mainly of caseins and to a smaller extent whey proteins. Lactose is synthesized from glucose and galactose within the milk-secreting cell. Vitamins, minerals, salts and antibodies are transformed from the blood across the cell cytoplasm into the alveolar lumen.
Due to labour patterns and working hours, milking twice a day has long been the common practice in industrial nations. In countries where labour is inexpensive, more frequent milking is often practiced. During the last few decades, focus has increasingly been put on milking more frequently, in particular in high-yielding herds. There are many benefits associated with more-frequent milking.
Changing from milking twice a day to three times a day markedly increases milk production. In addition, lactation becomes more persistent and prolonged. The reason why milk production increases with a more frequent milking could be a more frequent exposure of hormones stimulating milk secretion to the mammary gland. However, as mentioned above, milk contains an inhibitor with negative feedback control on milk secretion.
More frequent removal of this inhibitor therefore results in higher production. Cows with a small udder cistern are more sensitive to the frequency of milking. Smaller the cisterns are more susceptible to frequent milk removal.

PRIMARY PRODUCTION OF MILK
Dairy farming is a class of agriculture for long-term production of milk , which is processed either on the farm or at a dairy plant, either of which may be called a dairy for eventual sale of a dairy product. Although any mammal can produce milk, commercial dairy farms are typically one-species enterprises. In developed countries, dairy farms typically consist of high producing dairy cows. Other species used in commercial dairy farming include goats , sheep , and camels.
