The dietary treatments were a non-supplemented basal diet or the basal diet supplemented with ppm selenium in either an organic or inorganic form.

    Submit blood samples or reproductive tract swabs for disease testing. Have veterinarian examine repeat breeders; treat if infection is present. (See suggestions for uterine infection, page 3). Re-evaluate semen handling and insemination techniques. Attend retraining session for artificial insemination technique. The female counterpart to a bull is a cow, while a male of the species that has been castrated is a steer, ox, or bullock, although in North America, this last term refers to a young bull, [citation needed] and in Australia to a draught of these terms varies considerably with area and dialect. Colloquially, people unfamiliar with cattle may refer to both castrated and intact animals.

    Dose: mcg per day Often not contained, or not enough in your prenatal vitamin Limit: mcg per day. Very high doses of selenium can be toxic. 1Presented at the Pacific Northwest Animal Nutrition Conference, Vancouver, BC, Canada.

After 75Se intravenous injection, the highest levels of 75Se were found in the kidney followed by seminal vesicles and testicles. Progressive selenium deficiency was associated with. Selenium is stored in the tissues in varying density: 30% in the liver, 30% in muscle, 15% in the kidney, 10% in the plasma, and the remaining 15% throughout other organs.4, 10 Concentrations of free selenium are greatest in the renal cortex and pituitary gland, followed by the thyroid gland, adrenals, testes, ovaries, liver, spleen, and cerebral cortex, 12Cited by: Selenium and glutathione peroxidase distribution in bovine semen and selenium retention by the tissues of the reproductive tract in the bull.

In vivo and in vitro studies were conducted to investigate the chemical forms by ion-exchange chromatography of selenium (Se) present in rat and ovine spermatozoa. After injection with 75Se-selenite, the form of 75Se in rat sperm was selenocysteine, but selenocysteine and selenomethionine (SeMet) were present in ovine sperm.

The guinea pig, as a livestock species, is still developing and growing throughout Peru and neighboring countries, as reflected by its increasing export since However, the selection of proven fertile males is tedious due to the absence of seminal parameter standards and the lack of safe semen collection techniques.

Thus, pregnancy detection or live births are required for males&rsquo. Selenium Plays Key Role in Fertility Written by Holtorf Medical Group December 8, A research team, led by Melanie Ceko, looked at the role of selenium in the ovaries, and found that selenium is crucial to the development of healthy ovarian follicles.

Free radical damage is caused by radiation, exposure to environmental chemicals, poor diet, lack of antioxidants in the diet and nutrient deficiencies.

Selenium is a powerful male fertility enhancing nutrient, but it is also just one of several so called fertility-neutraceuticals. Clinical research studies have consistently shown that oxidative stress is the single biggest factor for decreased male fertility through DNA damage 2.

Things that are not checked as part of a routine breeding soundness evaluation, but which can have profound effects on breeding success include: • Serving capacity or mating ability – some physical and reproductive organ problems keep bulls from breeding cows.
