Mineral Nutrients in Australian Molasses for Fattening Cattle
نویسنده
چکیده
For feeding in large proportions to fatten beef cattle, Australian molasses have the following mineral nutrient characteristics: (a) all provide adequate to excess amounts of K, Ca, Mg, S, Cl, Co and Fe; (b) all are very deficient in P; (c) Na is deficient in some molasses from the Northern region; (d) Cu, Zn and Mn are all adequate for the lowest NRC level, but many molasses need supplementation to reach the ARC level; (e) the costs of supplementing Na, Cu and Zn are insignificant, but P supplements for most potential feeds would cost 0.7 to 1.4 $/head/day.
