Gestation is the period of development during the carrying of an embryo , and later fetus , inside viviparous animals (the embryo develops within the parent). It is typical for mammals , but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth .
52-783: The Big Bull was a large (14 metres × 21 metres) Holstein bull fibreglass model located near Wauchope, New South Wales , Australia . When open, it contained a gift shop on the ground floor and a beef display. It was located just off the Oxley Highway between Wauchope and the Pacific Highway . The structure was torn down in October 2007. The Big Bull notably had a swinging set of testicles. 31°26.3514′S 152°44.5662′E / 31.4391900°S 152.7427700°E / -31.4391900; 152.7427700 This article about an Australian building or structure

The breed currently averages 7,655 litres/year throughout 3.2 lactations with pedigree animals averaging 8,125 litres/year over an average of 3.43 lactations. By adding, lifetime production therefore stands at around 26,000 litres. Black and white cattle from Europe were introduced into

Class B is for a calf by a bull registered or dual registered in the Herd Book or in the Supplementary Register and out of a foundation cow or heifer registered in Class A or B of the Supplementary Register and containing between 75% and 87.4% Holstein genes or Frisian genes. For inclusion in the Pure (Holstein or Friesian) herd book,
208-614: A huge increase in Holstein bloodlines in the UK, proponents of the traditional British Friesian did not see things that way, and maintain these criteria do not reflect the true profitability or the production of the Friesian cow. Friesian breeders say modern conditions in the UK, similar to the 1950s through to the 1980s, with low milk price and the need for extensive, low-cost systems for many farmers, may ultimately cause producers to re-examine

Russell, of Lawrence, Mass., and three animals from East Friesland , imported by Gen. William S. Tilton of the National Military Asylum, Togus, Maine, formed the nucleus of the Holstein Herd Book. The Trina Holstein breed was established by the Merrill farming family in Maine in
312-504: A tendency to higher protein percentage, and, therefore, higher milk price. An 800-kg Holstein has a higher daily maintenance energy requirement than the 650-kg Friesian. Friesians have also been disadvantaged through the comparison of their type to a Holstein base. A separate "index" be composed to greater has been suggested to reflect the aspects of maintenance for bodyweight, protein percentage, longevity, and calf value. National Milk Records figures suggest highest yields are achieved between

The considerable advantage, compared to the UK, for example, can be explained by several factors: The golden age of Friesian breeding occurred during the last 50 years, greatly helped lately by embryo transfer techniques, which permitted a huge multiplication of bulls entering progeny testing of elite, bull-mother cows. Friesian bull, Osborndale Ivanhoe , b. 1952, brought stature, angularity, good udder conformation, and feet and leg conformation, but his daughters lacked strength and depth. His descendants included: Brachyspina syndrome (BS)

Starbuck (2)II , clone of the famous CIAQR sire Hanoverhill Starbuck , was born on 7 September 2000 in Saint-Hyacinthe . The clone is a result of the combined efforts of CIAQ, L'Alliance Boviteq Inc, and the Faculté de médecine vétérinaire de l' Université de Montréal . The cloned calf was born 21 years and 5 months after Starbuck's own birth date and just under 2 years after his death (17 September 1998). The calf weighed 54.2 kg at birth and showed
572-584: Is also a known colour. This colour is produced by white hairs mixed with the black hairs giving the cow a bluish tint. This colouring is also known as 'blue roan' in some farm circles. They are famed for their high dairy production, averaging 22,530 pounds (10,220 kg) of milk per year. Of this milk, 858 pounds (3.7%) are butterfat and 719 pounds (3.1%) are protein. A healthy calf weighs 40 to 50 kg (88 to 110 lb) or more at birth. A mature Holstein cow typically weighs 680–770 kg (1,500–1,700 lb), and stands 145–165 cm (57–65 in) tall at

With the growth of the New World , a demand for milk developed in North America and South America, and dairy breeders in those regions at first imported their livestock from the Netherlands. However, after about 8,800 Friesians ( black pied German cows ) had been imported, Europe stopped exporting dairy animals due to disease problems. Today,

In high-income countries, prenatal care typically involves monthly visits during the first two trimesters, with an increasing number of visits closer to delivery. At these visits, healthcare providers will evaluate a variety of parental and fetal metrics, including fetal growth and heart rate, birth defects , maternal blood pressure, among others. After birth, health care providers will measure
832-561: The British Friesian Cattle Society . The Livestock Journal of 1900 referred to both the "exceptionally good" and "remarkably inferior" Dutch cattle. The Dutch cow was also considered to require more quality fodder and need more looking after than some English cattle that could easily be out-wintered. In an era of agricultural depression, breed societies notably had flourished, as a valuable export trade developed for traditional British breeds of cattle. At

A settler described them thus, "the cows were of the size of oxen, their colors clear black and white in large patches; very handsome". In 1810, a bull and two cows were imported by the Hon. William Jarvis for his farm at Wethersfield, Vermont . About the year 1825, another importation
936-528: The Roman army ; these fought successfully in the various Roman wars. The Frisii bred the same strain of cattle unadulterated for 2,000 years, except from accidental circumstances. In 1282 AD, floods produced the Zuiderzee , a formed body of water that had the effect of separating the cattle breeders of the modern day Frisians into two groups. The western group occupied West Friesland , now part of North Holland;

Birth normally occurs at a gestational age of about 40 weeks, though it is common for births to occur from 37 to 42 weeks. Labor occurring prior to 37 weeks gestation is considered preterm labor and can result from multiple factors, including previous preterm deliveries. Prenatal care
1040-470: The Dutch or Holstein breed". Holstein-Friesians were found throughout the rich lowlands of the Netherlands, northwestern provinces of Germany, Belgium and northern France. The breed did not become established in Great Britain at the time, nor was it used in the islands of Jersey or of Guernsey , which bred their own special cattle named after the islands . Their laws prohibited using imports from

They probably brought cattle with them from their native land and crossed them with cattle purchased in the colony. For many years afterwards, the cattle here were called Dutch cattle and were renowned for their milking qualities. The first recorded imports were more than 100 years later, consisting of six cows and two bulls. These were sent in 1795 by

#17327866495371144-626: The attributes of the British Friesian. This animal came to dominate the UK dairy cow population during these years, with exports of stock and semen to many countries throughout the world. Although the idea of "dual-purpose" animals has arguably become outmoded, the fact remains that the Friesian is eminently suitable for many farms, particularly where grazing is a main feature of the system. Proponents argue that Friesians last for more lactations through more robust conformation, thus spreading depreciation costs. An added advantage of income from
1196-605: The baby's weight, vital signs, reflexes, head circumference, muscle tone, and posture to help determine the gestational age. Various factors can influence the duration of gestation, including diseases in pregnancy and adequate prenatal care. The rates of morbidity and pre-existing diseases that predispose mothers to life-threatening, pregnancy-related complications in the United States are increasing. Inaccessibility of prenatal care may partially explain this ongoing disparity. During gestation in placental mammals there
1248-482: The breed is used for milk in the north of Europe, and for meat in the south of Europe. After 1945, European cattle breeding and dairy products became increasingly confined to certain regions due to the development of national infrastructure. This change led to the need to designate some animals for dairy production and others for beef production; previously, milk and beef had been produced from dual-purpose animals. Today, more than 80% of dairy production takes place north of
1300-561: The continent for breeding purposes. After World War II , breeders on the islands needed to restore their breeds, which had been severely reduced during the war, and imported almost 200 animals. Canadian breeders sent a gift of three yearling bulls to help establish the breed. The pure Holstein Breed Society was started in 1946 in Great Britain, following the British Friesian Cattle Society. The breed

The people were known for their care and breeding of cattle. The Frisii, preferring pastoral pursuits to warfare, paid a tax of ox hides and ox horns to the Roman government, whereas the Batavii furnished soldiers and officers to

Trina has traced back sixteen generations to one of the first cows imported into the United States. There are thirty generations of Trina Holstein offspring today. After about 8,800 Holsteins had been imported, a cattle disease broke out in Europe and importation ceased. In

They were so few in number, they were not included in the 1908 census. In 1909, though, the society was formed as the British Holstein Cattle Society, soon to be changed to British Holstein Friesian Society and, by 1918, to

The rich polder land in the Netherlands is unsurpassed for the production of grass, cattle, and dairy products. Between the 13th and 16th centuries, the production of butter and cheese was enormous. Historic records describe heavy beef cattle, weighing from 2,600 to 3,000 pounds each. The breeders had

Entry from then until 1921, when grading up was introduced, was by pedigree only. Gestation The time interval of a gestation is called the gestation period . In obstetrics , gestational age refers to the time since the onset of

1664-421: The fifth and seventh lactations; if so, this is particularly so for Friesians, with a greater lift for mature cows, and sustained over more lactations. However, production index only takes the first five lactations into account. British Friesian breeding has certainly not stood still, and through studied evaluation, substantial gains in yield have been achieved without the loss of type. Friesians were imported into
1716-607: The goal of producing as much milk and beef as possible from the same animal. The selection , breeding and feeding have been carried out with huge success. Inbreeding was not tolerated, and (distinct) families never arose, although differences in soil in different localities produced different sizes and variations. A Corporate Watch report on Dystopian Farming cited a 2004 study from the Journal of Dairy Science identified that between 96 and 98% of UK Holsteins were inbred to some degree, compared with around 50% in 1990.

Despite their efforts to block the farm from view of the press, news cameras broadcast this as breaking news among many of the country's top news stations. Since then, this calf had been rumored to have been put down to protect the owners, the Eatons, from invasions of the press. While interest in increasing production through indexing and lifetime profit scores had

In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). In humans, pregnancy can be defined clinically, biochemically or biologically. Clinically, pregnancy starts from first day of
1924-590: The late 19th century, there was enough interest among Friesian breeders to form associations to record pedigrees and maintain herd books. These associations merged in 1885, to found the Holstein-Friesian Association of America. In 1994, the name was changed to Holstein Association USA . The 2008 average actual production for all USA Holstein herds that were enrolled in production-testing programs and eligible for genetic evaluations
1976-524: The line between Bordeaux and Venice , and more than 60% of the cattle in Europe are found there as well. Today's European breeds, national derivatives of the Dutch Friesian, have become very different animals from those developed by breeders in the United States, who use Holsteins only for dairy production. As a result, breeders have imported specialized dairy Holsteins from the United States to cross-breed them with European black-and-whites. Today,

Very respectable grades can be obtained, commensurate with beef breeds, thereby providing extra income for the farm. Such extensive, low-cost systems may imply lower veterinary costs, through good fertility, resistance to lameness, and

It is similar to viviparity in that the embryo develops within the mother's body. Unlike the embryos of viviparous species, ovoviviparous embryos are nourished by the egg yolk rather than by the mother's body. However,

2184-406: The mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonadotropin (hCG) levels rise above 25 mIU/mL. Biologically, pregnancy starts at implantation of the fertilized egg. Human pregnancy can be divided into three trimesters, each approximately three months long: the first, second, and third trimester. The first trimester is from the last menstrual period through
2236-585: The rate of inbreeding in the UK has risen significantly since 1990. Up to the 18th century, the British Isles imported Dutch cattle, using them as the basis of several breeds in England and Scotland. The eminent David Low recorded, "the Dutch breed was especially established in the district of Holderness , on the north side of the Humber ; northward through the plains of Yorkshire . The finest dairy cattle in England...", of Holderness in 1840 still retained

Historical records suggest these cattle were black, and the Friesian cattle at this time were "pure white and light coloured". Crossbreeding may have led to the foundation of the present Holstein-Friesian breed, as the cattle of these two tribes from then are described identically in historical records. The portion of
2392-431: The shoulder. Holstein heifers should be bred by 11 to 14 months of age, when they weigh 317–340 kg (699–750 lb) or 55% of adult weight. Generally, breeders plan for Holstein heifers to calve for the first time between 21 and 24 months of age and 80% of adult body weight. The gestation period is about nine and a half months. Near 100 BC, a displaced group of people from Hesse migrated with their cattle to
2444-636: The term "Holstein" is used to describe North or South American stock and the use of that stock in Europe, particularly in Northern Europe. "Friesian" is used to describe animals of traditional European ancestry that are bred for both dairy and beef use. Crosses between the two are described as "Holstein-Friesian". Holsteins have distinctive markings, usually black and white or red and white in colour, typically exhibiting piebald patterns. On rare occasions, some have both black and red colouring with white. The red factor causes this unique colouring. 'Blue'
2496-487: The time of the survey, i.e. including young stock. DEFRA lists just over 2 million adult dairy cattle in the UK. Holstein in this instance, and indeed in all modern discussion, refers to animals traced from North American bloodlines, while Friesian refers to indigenous European black and white cattle. Criteria for inclusion in the Supplementary Register (i.e. not purebred) of the Holstein UK herd book are: Class A
2548-472: Was 23,022 pounds (10,443 kg) of milk, 840 pounds (380 kg) of butterfat, and 709 pounds (322 kg) of protein per year. Total lifetime productivity can be inferred from the average lifetime of US cows. This has been decreasing regularly in recent years and now stands at around 2.75 lactations, which when multiplied by average lactation yield above gives around 61,729 pounds (28,000 kg) of milk. The current national Holstein milk production leader

In viviparous animals , the embryo develops inside the body of the mother, as opposed to outside in an egg ( oviparity ). The mother then gives live birth. The less developed form of viviparity is called ovoviviparity , in which the mother carries embryos inside eggs. Most vipers exhibit ovoviviparity. The more developed form of viviparity
