EXCRETION LEVEL OF TRACE MINERALS IN BROILERS FED ORGANIC MINERAL

Organic Trace Minerals for Broilers and Breeders

Growth performance, carcass characteristics, plasma minerals, and fecal mineral excretion in grower-finisher swine fed diets with levels of trace minerals lower than common industry levels

Methods: Pigs (n = 6024) were randomly distributed into four blocks of two barns per block and allotted within block to diets with either Normal (industry levels) or Reduced TM supplementation. Growth performance was measured for each barn, and individual carcass characteristics were recorded at a commercial packing plant. Fecal samples randomly obtained from at least eight pigs per barn were a...

The New Progresses in Trace Mineral Requirements of Broilers, a Review

Since 1994 till today a few up to date have been made on the NRC (1994) recommendations for trace mineral requirements of broilers. The high prevalence of skeletal disorders in modern broilers could be a consequence of the uncoordinated growth rate and mineral nutrition. The commercial companies of broiler production often use a huge safety margin of trace minerals in feed formulation, which wi...

Effects of added chelated trace minerals, organic selenium, yeast culture, direct-fed microbials, and Yucca schidigera extract in horses: II. Nutrient excretion and potential environmental impact.

The objective of this study was to test the hypothesis that an equine diet formulated with chelated trace minerals, organic selenium, yeast culture, direct-fed microbials (DFM) and Yucca schidigera extract would decrease excretion of nutrients that have potential for environmental impact. Horses were acclimated to 100% pelleted diets formulated with (ADD) and without (CTRL) the aforementioned a...

Evaluation of trace mineral source and preharvest deletion of trace minerals from finishing diets on tissue mineral status in pigs

OBJECTIVE An experiment was conducted to evaluate dietary supplemental trace mineral source and deletion on mineral content in tissues. METHODS Weanling crossbred pigs (n = 144; 72 barrows and 72 gilts; body weight [BW] = 7.4±1.05 kg) were used. A basal diet was prepared, and trace mineral premix containing either inorganic (ITM) or organic (OTM) trace minerals (Cu, Fe, Mn, and Zn) was added ...
