Mineral Nutrition and Its Impact on Reproduction
نویسنده
چکیده
Requirements have been published for 13 different minerals in beef cattle diets. Other minerals such as chlorine, chromium, molybdenum, and nickel are known to be essential for beef cattle; however, there is currently not enough data available to accurately determine requirements. For some of the required minerals, requirements vary depending on cow size and stage of production. This variability results from increased mineral demand for the products of conception and for milk production. For these minerals, requirements are always greatest during peak lactation and lowest for non-lactating cows in mid-gestation.

Trace Mineral Requirements for Dairy Cattle
A host of nutrients are needed by cattle to support functions associated with life, and to grow, reproduce, and nourish their offspring (i.e., produce milk). A vast amount of resources have been expended to quantify the amounts of specific nutrients needed to perform these function so that economically efficient diets can be formulated. Feeding diets that provide adequate, but not excessive, am...

متن کاملEffect of reproduction on the bioavailability of calcium, zinc and selenium.
Nutrient needs increase during pregnancy and lactation to support fetal growth and milk synthesis, respectively. Physiological adjustments that are made to meet those needs alter the fraction of ingested nutrient retained, or the bioavailability. Using stable isotopes as tracers, we measured calcium, zinc and selenium homeostasis in women during reproduction. The physiological response, and the...
متن کاملP-89: Role of Nutrition Diet with and without Mineral-Vitamin Elements on Superovulation of Mice
Background: The quality and quantity of the diet has undeniable effects on the reproduction of organisms. We examined the effects of two diets (with and without mineral supplementation-Vitamins) on super-ovulation in two strains of mice (B6D2F1 and NMRI) in Royan Institute, Tehran. Materials and Methods: For this purpose, 40 female mice (21 days) from each strain were divided into four experime...
