Peran Makromineral dalam Mengatasi Gangguan Reproduksi Ruminansia

Abstract

Macrominerals are one of the nutrients that play an important role in the growth, health, production, reproduction and immunity of animals. Ruminants need macrominerals such as calcium (Ca), phosphorus (P), magnesium (Mg), potassium (K), sodium (Na), chloride (Cl) and sulfur (S). Ruminant mineral requirements are influenced by several factors such as age, pregnancy status and lactation status. One of the consequences of mineral deficiency is reproductive disorders. Macromineral deficiencies affect the reproductive performance of ruminants directly or indirectly. Macrominerals have a direct effect on the the function of the pituitary gland like the time of estrus and ovulation is longer, delayed uterine involution, increased uterine prolapse, incidence of dystocia and retention of the placenta. Indirect effect through decreased nerve function, decreased appetite, the ability to absorb glucose, minerals, amino acids and decrease body weight. A comprehensive understanding of the macrominerals role on the ruminant’s reproductive function is needed to prevent reproductive disorders due to inappropriate mineral administration.
