چکیده

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 analyzed for zinc, copper, iron, and manganese. Plasma samples from six pigs per barn were analyzed for zinc, copper, and iron.

The effects of low levels of dietary trace minerals on the plasma levels, faecal excretion, health and performance of pigs in a hot African climate.

The present study was performed in order to evaluate the effects of lower than usual industry levels of dietary trace minerals on plasma levels, faecal excretion, performance, mortality and morbidity in growing-finishing pigs in a hot African climate. Group 1 (n = 100 pigs) received a diet with common industry levels of trace minerals. Group 2 (n = 100 pigs) received reduced dietary trace miner...

Effect of dietary trace mineral concentration and source (inorganic vs. chelated) on performance, mineral status, and fecal mineral excretion in pigs from weaning through finishing.

Two hundred and sixteen weanling gilts (6.65+/-0.08 kg) were used to determine the effects of decreasing supplemental concentrations of Zn, Cu, Fe, and Mn, and trace mineral source (inorganic vs. chelated) on growth performance, mineral status, and fecal mineral concentrations from weaning through development. The study was conducted over three trials with 72 pigs in each trial. Gilts were bloc...

Evaluation of trace mineral source and preharvest deletion of trace minerals from finishing diets for pigs on growth performance, carcass characteristics, and pork quality.

Weanling crossbred pigs (Sus scrofa; 72 barrows and 72 gilts; BW = 7.4 ± 1.1 kg) were used to evaluate dietary supplemental trace mineral (Cu, Fe, Mn, and Zn) source (inorganic vs. organic) and deletion (0, 2, 4, and 6 wk preharvest) on growth performance, carcass characteristics, and pork quality. Pigs were blocked by BW, ancestry, and sex, and randomly allotted to 24 pens, and fed a diet cont...

Effects of Irradiated Flaxseed on Performance, Carcass Characteristics, Blood Parameters, and Nutrient Digestibility in Broiler Chickens

The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...

Metabolism and Nutrition IV: Vitamins and Minerals and Feed Manufacturing

Research on which NRC trace mineral requirements are based was done with inorganic transitional minerals and purified and semi-purified diets. Research with organic trace minerals and standard rations have demonstrated that requirements are much lower than the levels set by NRC, due to the greater availability of these organic minerals. Further, not all organic minerals are the same. Pullets fr...
