Effect of Suplemental Organic Chromium and Fungi Ganoderma lucidum on Milk Production and Immune Respone in Lactating Cows

Abstract

ABSTRACT Chromium (Cr) is an essential miconutrient for humans and animals required [or carbohidrate, lipid, protein and nucleic acid metabolism, regulation hormonal and immune function. Gamxierma /ucidum, an fungus, has bioactivc compounds (polisaccharides) wich function for enhancing immune response and it can also be used to sY!1thesize organic Cr. The aim of this experiment was to determine the effect of organic Cr and Ganoderma fucidum suplementation on milk production and immune respon of laclating cows. Fifteen lactating cows grouped anJ allocated in the five treatments in randomize block design, fed a basal diet composed of 60% grass and 40% concentrate Suplementation on basal diet as treatment were : A= basal diet unsuplemented (control), B= 3 ppm inorganic Cr CrCh, C= 3 ppm organic Cr (fermentation product of fibrus feed with Ganoderma lucidum), 0= . Ganoderma lucidum (5 g/ 50 kg live weight) and E= Organic Cr + Ganoderma lucidum. The result showed that there is no significant differences on dry matter and organic matter intake, and milk production, but Cr intake and in milk increased with organic Cr supplementation and its combination with G. lucidum. Suplementation of Ganodcrma lucidum and its combination with organir. Cr tend to reduce somatic sel count, mastitis skor and coloni of microorganism in milk yield. It can be concluded thai Ganoderma lucidum and organic Cr in combination fom1 with Ganoderma lucidum can improved immune response of lactating cows.
