Effects of high dietary zinc intake in ruminants animals

18255

Zinc is a mineral which are necessary to be intake daily and absolutely essential for the healthy growth of humans, animals and plants. On a global scale, zinc deficiency is the most widespread of all micronutrient deficiencies and causes reduced yields of crops and animals. Therefore, in areas with intensive livestock production, zinc is often supplemented to diet of the animals for health reasons or as growth promoters by producers. Recent studies have demonstrated that zinc improved ruminant productivity when supplemented at levels six times or more its recommended level for sheep and cows. The present review examines the effects of high dietary zinc intake on rumen fermentation, haematological and biochemical parameters and productivity of ruminants based on results of the studies conducted in recent years.
