180-437: A better fit. Pasteurization is the process of heating milk to a high enough temperature for a short period of time to kill the microbes in the milk and increase keep time and decrease spoilage time. By killing the microbes, decreasing the transmission of infection, and elimination of enzymes the quality of the milk and the shelf life increases. Pasteurization is either completed at 63 °C (145 °F) for thirty minutes or
270-507: A breeding bull or sold and used for veal or beef . Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is about nine months. Newborn calves are separated from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf. Domestic cows can live beyond 20 years; however, those raised for dairy rarely live that long, as
360-427: A bull, ability to select from a large number of bulls, elimination of diseases in the dairy industry, improved genetics and improved animal welfare. Rather than a large bull jumping on a smaller heifer or weaker cow, AI allows the farmer to complete the breeding procedure within 5 minutes with minimum stress placed on the individual female's body. Dairy cattle are polyestrous, meaning they cycle continuously throughout
450-576: A calf. The cycle of insemination, pregnancy, parturition, and lactation is followed by a "dry" period of about two months before calving, which allows udder tissue to regenerate. A dry period that falls outside this time frames can result in decreased milk production in subsequent lactation. Dairy operations therefore include both the production of milk and the production of calves. Bull calves are either castrated and raised as steers for beef production or used for veal. The practice of dairy production has been criticized by animal rights proponents. Some of
540-441: A dairy farm are from interactions with cattle. Dairy animals are handled on a daily basis for a wide variety of purposes including health-related management practices and movement from freestalls to the milking parlor. Due to the prevalence of human-animal interactions on dairy farms, researchers, veterinarians, and farmers alike have focused on furthering our understanding of stockmanship and educating agriculture workers. Stockmanship
630-514: A dairy farm as a herd bull, to provide natural breeding for the herd of cows. A bull may service up to 50 or 60 cows during a breeding season. Any more and the sperm count declines, leading to cows "returning to service" (needing to be bred again). A herd bull may only stay for one season, as when most bulls reach over two years old their temperament becomes too unpredictable. Bull calves intended for breeding are commonly bred on specialized dairy breeding farms, not production farms. These farms are
720-419: A day of birth to reduce transmission of disease and simplify management of milking cows. Studies have been done allowing calves to remain with their mothers for 1, 4, 7 or 14 days after birth. Cows whose calves were removed longer than one day after birth showed increased searching, sniffing and vocalizations. However, calves allowed to remain with their mothers for longer periods showed weight gains at three times
810-416: A flash pasteurization is completed for 15 seconds at 72 °C (162 °F). By-products of milk include butterfat, cream, curds, and whey. Butterfat is the main lipid in milk. The cream contains 18–40% butterfat. The industry can be divided into 2 market territories; fluid milk and industrialized milk such as yogurt, cheeses, and ice cream. Whey protein makes up about 20% of milk's protein composition and

This day celebrating the " king of cheeses " originated in response to the two earthquakes hitting the area of origin in May 2012. The devastation was profound, displacing tens of thousands of residents, collapsing factories, and damaging historical churches, bell towers, and other landmarks. Years of cheese production were lost during
1170-550: A longevity of 10 lactations is possible. The chances of problems arising which may lead to a cow being culled are high, however; the average herd life of US Holstein is today fewer than 3 lactations. This requires more herd replacements to be reared or purchased. Over 90% of all cows are slaughtered for 4 main reasons: Cow longevity is strongly correlated with production levels. Lower production cows live longer than high production cows, but may be less profitable. Cows no longer wanted for milk production are sent to slaughter. Their meat
1260-612: A milk sample is taken from every farm and from every load of milk delivered to a processing plant. These samples are then tested for antibiotic and any milk testing positive is discarded and farm identified. Traceback to the dairy is undertaken by the FDA with further consequences including the possibility revocation of ability to sell milk. Nutrition plays an important role in keeping cattle healthy and strong. Implementing an adequate nutrition program can also improve milk production and reproductive performance. Nutrient requirements may not be

The Holstein Friesian is the main breed of dairy cattle in Australia, and said to have the "world's highest" productivity, at 10,000 litres (2,200 imp gal; 2,600 US gal) of milk per year. The average for a single dairy cow in the US in 2007 was 9,164 kg (20,204 lb) per year, excluding milk consumed by her calves, whereas
1530-428: A tie-stall system, the milking units are brought to the cows during each milking. These cattle are tethered within their stalls with free access to water and feed provided. In extensive systems, cattle are mainly outside on pasture for most of their lives. These cattle are generally lower in milk production and are herded multiple times daily to be milked. The systems used greatly depend on the climate and available land of
1620-439: A variety of fat supplements can benefit conception rates of lactating dairy cows. Some of these different fats include oleic acids , found in canola oil , animal tallow, and yellow grease; palmitic acid found in granular fats and dry fats; and linolenic acids which are found in cottonseed , safflower , sunflower , and soybean . Diets can additionally be formulated to strategically reduce methane emissions. Ruminants such as

A recent survey of Minnesota dairy farms revealed that 42.6% of workers learned stockmanship techniques from family members, and 29.9% had participated in stockmanship training. However, as the growing U.S. dairy industry increasingly relies on an immigrant workforce, stockmanship training and education resources become more pertinent. Clearly communicating and managing
2070-584: Is a major North American producer of grated Parmesan and has been selling it since 1945. A number of Wisconsin cheesemakers , some founded by Italian immigrants, produce Parmesan in whole wheels. A number of non-European parmesan producers have taken strong objection to the attempts of the European Union to globally control the trademark of the Parmesan name, claiming that it is more about control of trade than control of quality. Several American manufacturers have been investigated for allegedly going beyond
2160-493: Is allowed as a starter, together with calf rennet. The only additive allowed is salt , which the cheese absorbs while being submerged for 20 days in brine tanks saturated to near-total salinity with Mediterranean sea salt. The product is aged a minimum of one year and an average of two years; an expert from the Consorzio typically conducts a sound test with a hammer to determine if a wheel has finished maturing. The cheese
2250-533: Is an Italian hard , granular cheese produced from cow's milk and aged at least 12 months or, outside the European Union and Lisbon Agreement countries, a locally produced imitation. Parmigiano Reggiano is named after two of the areas which produce it, the Italian provinces of Parma and Reggio Emilia ( Parmigiano is the Italian adjective for the city and province of Parma and Reggiano
2340-571: Is an Italian cheese similar to Parmigiano Reggiano, but is produced mainly in Lombardy , where Padano refers to the Po Valley ( Pianura Padana ); the cows producing the milk may be fed silage as well as grass; the milk may contain slightly less fat, milk from several different days may be used, and must be aged a minimum of 9 months. Reggianito is an Argentine cheese similar to Parmigiano Reggiano. Developed by Italian Argentine cheesemakers,
2430-421: Is considered in a good state of welfare if it is able to express its innate behaviour, comfortable, healthy, safe, well nourished, and is not suffering from harmful states such as distress, fear and pain. Good animal welfare requires disease prevention and veterinary treatment, appropriate shelter, management, nutrition, and humane handling. If the animal is slaughtered then it is no longer "good animal welfare". It
2520-713: Is falling rapidly, with 51% of U.S. milk in 2007 produced by the 3,100 herds with over 500 cows. The United Kingdom dairy herd overall has nearly 1.5 million cows, with about 100 head reported on an average farm. In New Zealand, the average herd has more than 375 cows, while in Australia, there are approximately 220 cows in the average herd. The United States dairy herd produced 84.2 billion kilograms (185.7 billion pounds) of milk in 2007, up from 52.9 billion kilograms (116.6 billion pounds) in 1950, yet there were only about 9 million cows on U.S. dairy farms—about 13 million fewer than there were in 1950. The top breed of dairy cow within Canada's national herd category
2610-536: Is known as a certified name (which is not the same as a brand name ). In 2008, an EU court determined that the name Parmesan in Europe only refers to Parmigiano Reggiano and cannot be used for imitation Parmesan. Thus, in the European Union , Parmigiano Reggiano is a protected designation of origin (PDO); legally, the name refers exclusively to the Parmigiano Reggiano PDO cheese manufactured in
2700-558: Is legally protected in the European Union and, in Italy, exclusive control is exercised over the cheese's production and sale by The Consortium of Parmigiano Reggiano, which was created by a governmental decree. Each wheel must meet strict criteria early in the aging process, when the cheese is still soft and creamy, to merit the official seal and be placed in storage for aging. Because it is widely imitated, Parmigiano Reggiano has become an increasingly regulated product, and in 1955 it became what
2790-462: Is of relatively low value and is generally used for processed meat. Another factor affecting milk production is the stress the cow is faced with. Psychologists at the University of Leicester , UK, analyzed the musical preference of milk cows and found out that music actually influences the dairy cow's lactation. Calming music can improve milk yield, probably because it reduces stress and relaxes

2880-404: Is often shaved or grated over other dishes such as salads . Slivers and chunks of the hardest parts of the crust (also called the rind) are sometimes simmered in soups, broths, and sauces to add flavor. They can also be broiled and eaten as a snack, if they have no wax on them, or infused in olive oil or used in a steamer basket while steaming vegetables. According to legend, Parmigiano Reggiano
2970-453: Is produced daily, and it can show a natural variability. True Parmigiano Reggiano cheese has a sharp, complex fruity/nutty taste with a strong savory flavor and a slightly gritty texture. Inferior versions can impart a bitter taste. A typical Parmigiano Reggiano wheel is about 18–24 cm (7–9 in) high, 40–45 cm (16–18 in) in diameter , and weighs 38 kg (84 lb). All producers of Parmigiano Reggiano cheese belong to

The U.S. Food and Drug Administration (FDA) has ruled that rBST recombinant bovine somatotropin (rBST), recombinant bovine growth hormone (rBGH) s harmless to people while
4500-596: The United States, the Code of Federal Regulations includes a Standard of Identity for "Parmesan and Reggiano cheese". This defines both aspects of the production process and of the final result. In particular, Parmesan must be made of cow's milk, cured for 10 months or more, contain no more than 32% water, and have no less than 32% milkfat in its solids. Similarly, the Canadian regulation only defines moisture and fat levels, with no restriction on aging time. Kraft Foods

Since the 1950s, artificial insemination (AI) is used at most dairy farms; these farms may keep no bull. Artificial insemination uses estrus synchronization to indicate when the cow is going through ovulation and is susceptible to fertilization. Advantages of using AI include its low cost and ease compared to maintaining

These behaviors can also be related to the productivity of the cows. Likewise, stress, disease, and discomfort negatively affect milk productivity. Therefore, it can be said that it is in the best interest of the farmer to increase eating, rumination, and lying down and decrease stress, disease, and discomfort to achieve
5490-461: The cows in the herd instead of using replacer. A day-old calf consumes around 5 liters of milk per day. Cattle are social animals; their ancestors tended to live in matriarchal groups of mothers and offspring. The formation of "friendships" between two cows is common and long lasting. Traditionally individual housing systems were used in calf rearing, to reduce the risk of disease spread and provide specific care. However, due to their social behaviour

It may be kept by
5850-508: The feed. Dairy cows with good rumen health are likely to be more profitable than cows with poor rumen health—as a healthy rumen aids in digestion of nutrients. An increase in the time a cow spends ruminating is associated with the increase in health and an increase in milk production. The productivity of dairy cattle is most efficient when the cattle have a full rumen. Also, the standing action while feeding after milking has been suggested to enhance udder health. The delivery of fresh feed while

It has been seen that calves housed in grouped penning were found to eat more feed than those in single pens, suggesting social facilitation of feeding behaviour in the calves. Play behaviour in pre-weaned dairy calves has also been suggested to help build social skills for later in life. It has been seen that those reared in grouped housing are more likely to become

When they stand too long, cows become stressed, lose weight, get sore feet, and produce less milk. To ensure that the dairy cows lie down as much as needed, the stalls must be comfortable. A stall should have a rubber mat and bedding , and be large enough for the cow to lie down and get up comfortably. Signs that

6480-512: The major source of stocks for artificial insemination . The dairy cow produces large amounts of milk in its lifetime. Production levels peak at around 40 to 60 days after calving. Production declines steadily afterwards until milking is stopped at about 10 months. The cow is "dried off" for about sixty days before calving again. Within a 12 to 14-month inter-calving cycle, the milking period is about 305 days or 10 months long. Among many variables, certain breeds produce more milk than others within
6570-413: The maximum productivity possible. Also, estrous behaviors such as mounting can be a sign of cow comfort, because if a cow is lame, nutritionally deficient, or housed in an overcrowded barn, its estrous behaviors are altered. Feeding behaviors are important for the dairy cow, as feeding is how the cow ingests dry matter. However, the cow must ruminate to fully digest the feed and utilize the nutrients in
6660-543: The multiplication of progeny from elite cows. Such cows are given hormone treatments to produce multiple embryos. These are then 'flushed' from the cow's uterus . 7–12 embryos are consequently removed from these donor cows and transferred into other cows who serve as surrogate mothers . This results in between three and six calves instead of the normal single or (rarely) twins. Farmers in some countries sometimes administer hormone treatments to dairy cows to increase milk production and reproduction. About 17% of dairy cows in
6750-649: The production cycle. Market calves are generally sold at two weeks of age and bull calves may fetch a premium over heifers due to their size, either current or potential. Calves may be sold for veal , or for one of several types of beef production , depending on available local crops and markets. Such bull calves may be castrated if turnout onto pastures is envisaged, to make them less aggressive. Purebred bulls from elite cows may be put into progeny testing schemes to find out whether they might become superior sires for breeding. Such animals can become extremely valuable. Most dairy farms separate calves from their mothers within
6840-496: The rate of early removals as well as more searching behavior and better social relationships with other calves. After separation, some young dairy calves subsist on commercial milk replacer , a feed based on dried milk powder. Milk replacer is an economical alternative to feeding whole milk because it is cheaper, can be bought at varying fat and protein percentages, and is typically less contaminated than whole milk when handled properly. Some farms pasteurize and feed calves milk from
6930-472: The region in which the farm is situated. To maintain lactation , a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a "dairy bull" or a "beef bull." Female calves ( heifers ) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as
7020-407: The rind with the Consorzio 's logo. Those that do not pass the test used to have their rinds marked with lines or crosses all the way around to inform consumers that they are not getting top-quality Parmigiano Reggiano; more recent practices simply have these lesser rinds stripped of all markings. Traditionally cows are fed only on grass or hay , producing grass-fed milk. Only natural whey culture
7110-514: The same average value for a single cow in Israel was reported in the Philippine press to be 12,240 kg (26,980 lb) in 2009. High production cows are more difficult to breed at a two-year interval. Many farms take the view that 24 or even 36 month cycles are more appropriate for this type of cow. Dairy cows may continue to be economically productive for many lactation cycles. In theory
7200-432: The same depending on the animal's age and stage of production. Diets are formulated to meet the dairy cow's energy and amino acid requirements for lactation, growth, and/or reproduction. Forages, which refer especially to anything grown in the field such as hay, straw, corn silage, or grass silage, are the most common type of feed used. The base of most lactating dairy cattle diets is high quality forage. Cereal grains , as
7290-578: The same stock often being used for both meat and milk production. Today, the bovine industry is more specialized and most dairy cattle have been bred to produce large volumes of milk. Dairy cows may be found either in herds or dairy farms , where dairy farmers own, manage, care for, and collect milk from them, or on commercial farms. Herd sizes vary around the world depending on landholding culture and social structure. The United States has an estimated 9 million cows in around 75,000 dairy herds, with an average herd size of 120 cows. The number of small herds
7380-409: The shelf underneath it is then cleaned every seven days, and the cheese is turned. At 12 months, the Consorzio del Formaggio Parmigiano Reggiano ( lit. ' Parmigiano Reggiano Cheese Consortium ' ) inspects every wheel. The cheese is tested by a master grader who taps each wheel to identify undesirable cracks and voids within the wheel. Wheels that pass the test are then heat-branded on
7470-476: The size of rice grains). The temperature is then raised to 55 °C (131 °F) with careful control by the cheese-maker. The curd is left to settle for 45–60 minutes. The compacted curd is collected in a piece of muslin before being divided in two and placed in molds. There are 1,100 litres (290 US gal) of milk per vat, producing two cheeses each. The curd making up each wheel at this point weighs around 45 kilograms (99 lb). The remaining whey in
7560-432: The stalls may not be comfortable enough for the cows are the cows are standing, either ruminating or not, instead of lying down, or perching, which is when the cow has its front end in the stall and their back end out of the stall. Dried manure, almond shells, straw, sand, or waterbeds are used for cow bedding. There are two types of housing systems in dairy production, free style housing and tie stall. Free style housing
7650-417: The system. Once an individual's welfare is reduced, so does her efficiency and production. This creates more cost and time on the operation, therefore most farmers strive to create a healthy, hygienic, atmosphere for their cattle. As well as provide quality nutrition that keep the cows yield high. The production of milk requires that the cow be in lactation , which is a result of the cow having given birth to
7740-428: The vat was traditionally used to feed the pigs from which prosciutto di Parma was produced. The barns for these animals were usually just a few metres away from the cheese production rooms. The cheese is put into a stainless steel, round form that is pulled tight with a spring-powered buckle so the cheese retains its wheel shape. After a day or two, the buckle is released and a plastic belt imprinted numerous times with
7830-571: The year 4000 BC Also, there is evidence that monks started breeding these cows about 1000 years ago. The Ayrshire breed first originated in the County of Ayr in Scotland. It became regarded as a well established breed in 1812. The different breeds that were crossed to form the Ayrshire are not exactly known. However, there is evidence that several breeds were crossed with the native cattle to create
7920-403: The year. They tend to be on a 21 day estrus cycle. However for management purposes, some operations use synthetic hormones to synchronize their cows or heifers to have them breed and calve at the ideal times. These hormones are short term and only used when necessary. For example, one common protocol for synchronization involves an injection of GnRH (gonadotrophin releasing hormone). which increases
8010-516: Was created in the course of the Middle Ages in the comune (municipality) of Bibbiano , in the province of Reggio Emilia . Its production soon spread to the Parma and Modena areas. Historical documents show that in the 13th and 14th centuries, Parmigiano was already very similar to that produced today, which suggests its origins can be traced to far earlier. Some evidence suggests that the name
8100-472: Was used for Parmesan cheese in Italy and France in the 17th-19th century. It was praised as early as 1348 in the writings of Boccaccio ; in the Decameron , he invents a 'mountain, all of grated Parmesan cheese', on which 'dwell folk that do nought else but make macaroni and ravioli , and boil them in capon's broth, and then throw them down to be scrambled for; and hard by flows a rivulet of Vernaccia ,
