Oxytocin is a hormone that is produced naturally by the body, and which has a range of functions, including the stimulation of uterine contractions in the second and third stages of labour. During the early phases of pregnancy the uterus is relatively insensitive to the effects of oxytocin, while in the late phases the sensitivity is markedly increased. [9][10] Production and secretion of oxytocin is controlled by a positive feedback mechanism, where its initial release stimulates production and release of further oxytocin. Estrous Control and Synchrony in Cattle Exogenous hormones can mimic the hormones of the natural estrous cycle in cattle. Endogenous oxytocin concentrations in the brain have been found to be as much as 1000-fold higher than peripheral levels.[46]. It plays a vital role in childbirth and lactation.

[44] The endocrine effects of hormonal oxytocin and the cognitive or behavioral effects of oxytocin neuropeptides are thought to be coordinated through its common release through these collaterals. The Leydig cells in some species have been shown to possess the biosynthetic machinery to manufacture testicular oxytocin de novo, to be specific, in rats (which can synthesize vitamin C endogenously), and in guinea pigs, which, like humans, require an exogenous source of vitamin C (ascorbate) in their diets. It is also synthesized and secreted in other tissues, including the brain, uterus, placenta, ovaries, and testes. It is involved in childbirth and breastfeeding. 10.

Effect of ACTH and oxytocin treatment on lactoferrin and citrate in cows' milk. Oxytocin enhances the aversive social memory, leading the rat to display a greater fear response when the aversive stimulus is encountered again. The most effective time for treatment is when uterine inertia begins to develop, before the contractions stop completely. With lactation and breastfeeding (chestfeeding), your babys sucking stimulates your pituitary to release oxytocin to push milk through your breast tissue.

ACTIONS: Oxytocin acts directly on the smooth musculature of the uterus in all species to induce rhythmic contractions, although in some species the uterine cervix does not respond to oxytocin. One theory states that oxytocin increases approach/avoidance to certain social stimuli and the second theory states that oxytocin increases the salience of certain social stimuli, causing the animal or human to pay closer attention to socially relevant stimuli.

These cells are called as alveoli and also helpful in birth. High doses of oxytocin saturate the receptor sites and make it ineffective as a uterotonic. The two genes are believed to result from a gene duplication event; the ancestral gene is estimated to be about 500 million years old and is found in cyclostomata (modern members of the Agnatha). [44] Oxytocin is also produced by some neurons in the paraventricular nucleus that project to other parts of the brain and to the spinal cord. 4-deamido-oxytocin) was performed in the following decade by Iphigenia Photaki.
