By Dr. David F. Jones, Ph.D., P.A.S. Methane production from ruminant animals has received a lot of attention in recent years and is still a primary focus today. Since methane is a waste product from rumen fermentation, it is possible to minimize the process of methane production with nutrition and products that promote greater efficiency […]
By Dr. David Jones, Ph.D., P.A.S. Along with amino acids and peptides, ammonia is part of the soluble protein (or ‘A’ fraction) of routine protein analysis. It is generated by the deamination (removal of nitrogen-containing amino groups) of proteins, which reduces the overall quality of the protein. Ammonia is a source of nitrogen for rumen […]
By Dr. Dave Jones, Ph.D., P.A.S. Fatty acids are components of lipid molecules most commonly stored in the form of a triglyceride (1 glycerol, 3 fatty acids). The nutritionally important component of fats are the fatty acids and they serve many different functions: Source of energy Affect breeding proficiency Modulators of the immune system Building […]
Today’s nutritional technology and knowledge make it easy to overlook the basics of dairy cow nutrition. This, in turn, makes it possible to complicate a ration with the inclusion of too many commodities. Don’t forget the basics. Dairy cows require nutrients and not feed ingredients.
By Dr. Dave Jones, Ph.D., P.A.S. Nitrates and ammonia can be found in forages and either one or both can reduce animal productivity. The oxygen-carrying capacity of the blood is decreased when nitrates bind to the hemoglobin, forming methemoglobin. Low blood oxygen inhibits cellular and energy metabolism by the cells. Ammonia increases blood pH, can […]
The Importance of Modulating the Gut Microbiota of Livestock to Improve Health By Dr. Pat Brown, Ph.D., P.A.S.; Dr. Dan Schauff, Ph.D., P.A.S.; Dr. Dave Jones, Ph.D., P.A.S.; Courtney Furst, Agri-King Area Manager The world has now been in the antibiotic era for over seventy years. These medications have revolutionized health care, with the number […]
By Drs. Pat Brown, Ph.D., and Dave Jones, Ph.D. The gastrointestinal tract (GI tract) marks the physical boundary between an animal and the contents of its intestines. This boundary allows direct contact between the immense surface area of the GI tract and the intestinal contents (digesta). The contents include a far-ranging mixture of undigested feed […]
