Optimize Reproduction with Novus® Trace Minerals
After calving, beef producers strive to get their herd rebred efficiently to shorten the
calving interval. Trace mineral nutrition affects uterine involution and resumption of ovarian activity, which are imperative to a cow returning to estrus and cycling after calving. Hormone regulation and production are also significantly affected by trace mineral nutrition and status.
After calving, a cow begins a regular estrous cycle starting with hypothalamus function. The hypothalamus produces gonadotropic-releasing hormone (GnRH), which requires calcium (Ca) and copper (Cu) to stimulate release. GnRH then causes the anterior pituitary gland to produce follicle-stimulating hormone (FSH) which stimulates the development and maturation of a follicle, and luteinizing hormone (LH) which causes ovulation of a follicle to occur. Ca, Cu and zinc (Zn) are crucial for FSH and LH production. Once a follicle is selected and ovulates, a corpus luteum (CL) forms on the ovary. Manganese (Mn) and magnesium (Mg) stimulate the CL to produce progesterone allowing pregnancy to be sustained if the egg has been fertilized.
With so many intricate pathways in the reproductive cycle of a cow, it is crucial to provide all essential nutrients in the highest quality, and most absorbable form. Since trace minerals are essential for the production and regulation of hormones, providing them at the right times and in highest quality form is imperative. Beef cows should be supplemented with either MAAC® or MINTREX® trace minerals, two high quality, complete minerals, beginning 60 days before the first cow calves and continuing through breeding season.
Novus® provides trace mineral solutions proven to optimize reproductive performance in beef cattle.
