A Hereford bull In general, the same words are used in different parts of the world, but with minor differences in the definitions.
Dairy cattle in Mangskog, Sweden, 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 month inter-calving cycle, the milking period is about days or 10 months long. Many farms take the view that 24 or even 36 month cycles are more appropriate for this type of cow. In theory a longevity of 10 Cows and their life 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. Infertility — failure to conceive and reduced milk production. Cows are at their most fertile between 60 and 80 days after calving.
Cows remaining "open" not with calf after this period become increasingly difficult to breed, which may be due to poor health. Failure to expel the afterbirth from a previous pregnancy, luteal cystsor metritisan infection of the uterus, are common causes of infertility. Mastitis — a persistent and potentially fatal mammary gland infection, leading to high somatic cell counts and loss of production.
Mastitis is recognized by a reddening and swelling of the infected quarter of the udder and the presence of whitish clots or pus in the milk. Lameness — persistent foot infection or leg problems causing infertility and loss of production. This leads to Laminitis and subsequent lameness, leaving the cow vulnerable to other foot infections and problems which may be exacerbated by standing in faeces or water soaked areas.
Production — some animals fail to produce economic levels of milk to justify their feed costs. Production below 12 to 15 litres of milk per day is not economically viable.
Cows no longer wanted for milk production are sent to slaughter. Their meat 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.
Calming music can improve milk yield, probably because it reduces stress and relaxes the cows in much the same way as it relaxes humans. Also, the standing action while feeding after milking has been suggested to enhance udder health. The delivery of fresh feed while the cattle are away for milking stimulates the cattle to fed upon return, potentially reducing the prevalence of mastitis as the sphincters have time to close while standing  This makes the pattern of feeding directly after being milked an ideal method of increasing the efficiency of the herd.
Cows have a high motivation to lie down  so farmers should be conscious of this, not only because they have a high motivation to lie down, but also because lying down can increase milk yield. Free style housing is where the cow is free to walk around and interact with its environment and other members of the herd.Like other mammals, to produce milk a dairy cow must keep giving birth, usually to a calf each year.
If nature was allowed to take its course—calves would suckle from their mother for several months, even up to a year. Mother cows, like most mammals, have a strong maternal bond.
One study found. The dairy industry spends a lot of money on advertising, to convince us that the breastmilk of a cow is healthy for us.
And cows need to be milked anyway, right? Our organic products are among the most natural and nutritious dairy products on the market. That’s because we believe in doing less—not more—when it comes to our food.
Dairy Cows Veal Calves Beef Cattle Fun Facts. Life of a Dairy Cow on a Factory Farm. Calves born to dairy cows are separated from their mothers immediately after birth. The female calves are raised to replace older dairy cows in the milking herd. Cows Used for Meat. In , million cattle were slaughtered for beef in the United States.
Often beginning their short lives on rangeland, calves are soon separated from their nurturing mothers and endure a series of painful mutilations.
The life of: dairy cows The dairy cows of today descend from wild ox, known as aurochs (Bos primigenius), that were found in most areas of Europe, Asia and North Africa. Cattle are thought to be one of the first animals to be domesticated, altering their feeding regime to increase their weight, inducing puberty earlier.
