Trace Mineral Nutrition in Poultry and Swine

Trace Mineral Nutrition in Poultry and Swine*

Trace minerals such as zinc, copper, and manganese are essential cofactors for hundreds of cellular enzymes and transcription factors in all animal species, and thus participate in a wide variety of biochemical processes. Immune development and response, tissue and bone development and integrity, protection against oxidative stress, and cellular growth and division are just a few examples. Defi...

Trace Mineral Nutrition Symposium: Exploring recent developments in swine and ruminants.

Trace Mineral Nutrition in Beef Cattle

Minerals can be divided into two main categories, 1) macro-minerals and 2) micro or trace minerals. Macro minerals are minerals that are needed/required in relatively large amounts in comparison to micro or trace elements which are needed/required in relatively small amounts. In general macro minerals are required at concentrations greater than 100 ppm of the diet and are often expressed as a p...

Advancements in Ruminant Trace Mineral Nutrition

Major advances in the field of trace mineral nutrition occurred in the twenty century. All of the trace minerals recognized as being important in ruminant nutrition were first shown to be essential in the 1900's with the exception of iron. Between 1920 and 1960 naturally occurring deficiencies of iodine, copper, cobalt, manganese, selenium, and zinc were first reported in cattle. Today it is co...

[Saponins in nutrition of swine, poultry and ruminants].

Saponins are glycosides found in many plants, which have soap character due to their surfactant properties. They work haemolytic and may cause symptoms of intoxication in high concentration. Among therapeutically relevant effects expectorative, anti-inflammatory and immune-stimulating effects have the highest ranking. Beyond that, saponins demonstrate antimicrobial properties particularly again...
