By David Donaldson, B.Agr, N.Sch, P.A.S. Molybdenum is required in small amounts in the diets of farm animals. No discussion on the requirements of Molybdenum (Mo) can be considered without also considering the Copper requirements of the animal. Early interest in Molybdenum (Mo) was less concerned with the daily requirement for Mo than the effects […]
By Dr. Aimee Hafla, Ph.D., P.A.S. Selenium is a necessary mineral for both humans and animals and naturally occurs in varying concentrations within the soil in all parts of the world. Available selenium in the soil is taken up by many plants, including some cereal grains and forages used for livestock feed. Selenium is an […]
By Dr. David Jones, Ph.D., P.A.S. Chromium is an important trace mineral. In fact, evidence for an essential role for chromium in humans came from patients receiving total parenteral nutrition (Anderson, R.A. 1995. Chromium and parenteral nutrition. Nutrition. 11:83-86). Patients developed diabetic symptoms that were alleviated by the addition of chromium. This finding created interest […]
By Dr. James C. Coomer, Ph.D., P.A.S. What is Manganese? Manganese (Mn) is an important trace mineral which animals require in very small quantities). It is involved in many aspects of both plant and animal life, primarily as an enzyme activator. Reduced growth or abnormal growth and development (such as perosis in chickens) is one […]
By Dr. Gene P. Gengelbach, Ph.D., P.A.S. Phosphorus (P) is a macro-mineral that is necessary for proper growth and development. However, in many areas of this country and around the world excess phosphorus in the surface water has become a serious source of pollution. It impacts the eutrophication of lakes and streams, whereby excess nutrients […]
By Dr. Dan Schauff, Ph.D., P.A.S. Magnesium is an essential macro-mineral that is required for numerous functions in the body of all mammals including dairy and beef cattle. These functions include: Co-factor for more than 300 enzyme systems involved in carbohydrate, protein, and lipid metabolism in the body; Nerve transmission and muscle contraction, and The […]
By Dr. Pat Brown The principal end products from the fermentation of corn to ethanol at dry-mill ethanol plants are Distillers Dried Grains with Solubles (DDGS), Carbon Dioxide (CO2), and, of course, ethanol. Of these, DDGS is the product of economic interest to livestock producers. From a bushel of corn, an ethanol plant will produce […]
By Dr. K.E. Lanka, Ph.D., P.A.S. The mineral sulfur (S) is one of seven generally recognized macro-minerals needed in the diets of dairy cattle and other animals. Sulfur is a mineral that is found in the amino acids methionine, cysteine (cystine), homocysteine, and taurine. It is also in the B-vitamins, thiamin, and biotin. It is […]
