A dairy farmer is a farmer who specializes in raising dairy cattle, specifically for milk and/or cheese products.\n\nBovine somatotropin (bST), or bovine growth hormone (BGH), is a protein hormone that occurs naturally in the pituitary gland of cattle. It is a factor controlling the amount of milk produced by a dairy cow. Bovine somatotropin is naturally in the milk extracted from a cow.\nContents\n[show]\n\n    * 1 Physiology\n    * 2 Recombinant Bovine Somatotropin (rbST) and rBGH\n          o 2.1 Related legal actions\n          o 2.2 Politics\n    * 3 See also\n    * 4 References\n    * 5 External references\n\n[edit]\n\nPhysiology\n\nBecause of protein homology, bovine growth hormone (GH) cross-reacts with the receptors of prolactin and placental lactogen — two hormones that stimulate the mammary tissue of a mature lactating cow in good health to produce more milk.\n\nSomatotropin and somatropin both refer to growth hormone (GH), a protein hormone produced by the mammalian anterior pituitary. The genes for GH, the amino acid sequence of the peptides, the receptor genes, and the receptor structures are recognizably homologous, though cross-species differences are significant enough to prevent most cross-species effects (i.e. bST does not "work" in humans).\n\nAlthough bST, insulin-like growth factor 1 (IGF1), and other cow hormones can be measured in cow milk, it is thought that the amounts are too small and digestion too complete for them to have any direct effect in humans, and there is no scientifically verifiable difference between the rBST concentration in milk from treated versus untreated cattle.\n[edit]\n\nRecombinant Bovine Somatotropin (rbST) and rBGH\n\nrbST (Recombinant Bovine Somatotropin) or rBGH (Recombinant Bovine Growth Hormone) is a controversial, genetically engineered version of the Bovine Growth Hormone used for increasing milk production in cows. While it is used in the United States, it is banned in Canada, the EU (The EU has actually taken a stance leaving it up to separate nations. One thing that they did not do is set a "maximum safe amount" of rBST which is actually something that Monsanto is citing in their PR campaign), Australia, and New Zealand.\n\nMonsanto developed a recombinant version of bST (rbST), which goes by the brand name Posilac®. Injected into dairy cattle, the product can increase milk production from 10% up to 40%. In November 1993, the product was approved for use in the U.S. by the FDA, and its use began in February 1994. The product is now sold in all 50 states. According to Monsanto, approximately one third of dairy cattle in the U.S. are injected with Posilac; approximately 13,000 dairy producers use the product. It is now the top selling dairy cattle pharmaceutical product in the U.S. The FDA does not require special labels for products produced from cows given rbST.\n\nHowever, use of the recombinant supplement has been controversial. Many groups claim not enough research has been done into human health effects despite over ten years of large-scale on-farm research before FDA approval, and subsequently these groups claim a possible increased risk of cancers, diabetes, and hypertension in consumers of products from rbST injected cows. Other fears include health problems for the injected cattle, and an economic concern for small farmers due to the increased supply of milk.\n\nUse of rBGH in cows also increases insulin growth factor (IGF-1) in milk. Although IGF-1 is important for normal development, some studies suggest that IGF-1 is involved in the progression of breast, prostate and colorectal cancer.\n\nAccording to Monsanto, milk and meat from cattle supplemented with rbST are safe. Monsanto also states that the only difference between milk from supplemented cattle and unsupplemented cattle is the amount of IGF1 — and that there is not even a difference in the concentration of bST.\n\nIn 1998, a Canadian committee found that while there were no

STH\nsomatotropic hormone\n\nGrowth hormone\nGrowth hormone is a polypeptide hormone synthesised and secreted by the anterior pituitary gland which stimulates growth and cell reproduction in humans and other vertebrate animals.\nThis article describes human growth hormone physiology, with brief mentions of the diseases of GH deficiency, GH excess (acromegaly and pituitary gigantism), as well as GH treatment, and HGH quackery. Each of these topics is treated more fully in separate articles.\n\n----------------------------------------------------------\n\nSth\n■  abbreviation south. \n\n----------------------------------------------------------

Prolactin has many effects, the most important of which is to stimulate the mammary glands to produce milk (lactation).\n\nIncreased serum concentrations of prolactin during pregnancy cause enlargement of the mammary glands of the breasts and increases the production of milk. However, the high levels of progesterone during pregnancy act directly on the breasts to stop ejection of milk. It is only when the levels of this hormone fall after childbirth that milk ejection is possible.\n\nSometimes, newborn babies (males as well as females) secrete a milky substance from their nipples. This substance is commonly known as Witch's milk. This is caused by the fetus being affected by prolactin circulating in the mother just before birth, and usually stops soon after birth.\n\nAnother effect, recently discovered by the University of Paisley and the Technische Hochschule Zürich, is to provide the body with sexual gratification after sexual acts. The hormone represses the effect of dopamine, which is responsible for sexual arousal, thus causing the male's refractory period. The amount of prolactin can be an indicator for the amount of sexual satisfaction and relaxation. Unusual high amounts are suspected to be responsible for impotence.\n\nOther possible functions of prolactin include the surfactant synthesis of the fetal lungs at the end of the pregnancy and immune tolerance of the fetus by the maternal organism during pregnancy.\nEstrogen is produced primarily by developing follicles in the ovaries, the corpus luteum and the placenta. Some estrogens are also produced in smaller amounts by other tissues such as the liver, adrenal glands and the breasts. These secondary sources of estrogen are especially important in post-menopausal women. Synthesis of oestrogenes starts in theca interna cells in the ovary, by the synthesis of androstenedione from cholesterol. Androstenedione is a substance of moderate androgenic activity. This compound crosses the basal membrane into the surrounding granulosa cells, where it is converted to estrone or estradiol, either immediately or through testosterone. There is evidence that a testosterone supplement can support female sexual desire (Braunstein et al, 2005). Many studies of the role of sex steroid hormones on sexual desire have been done in naturally post-menopausal women or women who have had their ovaries surgically removed. Such studies have found better correlation between sexual desire and androgen levels than for estrogen levels (Warnock et al, 2005). A clinical study found that women aged 18 to 44 who reported low sexual desire tended to have low levels of dehydroepiandrosterone sulfate (Davis et al, 2005). Dehydroepiandrosterone is an abundant sex steroid in women and like other steroids is efficiently sulfated. Dehydroepiandrosterone (DHEA) is a precursor steroid that can be converted to estrogens (estradiol) and androgens such as testosterone and 5α-dihydrotestosterone[1].

the hormone similar to our FSH hormone also stimulates them to up milk production... it evades me right now... but i wanna say it's called BSH.... i swear that's wrong, but it's from Monsanto company.... i haven't milked out cows in a long time! ;) anyhoo, they get monthly injections which stimulates their mammaries to up milk production.

Well i have own a man boob milk business, and i have discovered if you lick hamsters you can increase your milk yield by 75%.\nI am currently working with tescos and im making their whole milk!

if your doing this for school you can contact Bayer Corp. diagnostic division 800.331.4536 or lifescan.com both company's have programs to educate people about preventing and managing diabetes.They can get you in touch with a local rep who can provide a monitor, testing strips,research info and even presentation items.These companys spend millions each year to educate. why not take them at their word? Good luck.
