Effect of Pig Age at Market Weight and Magnesium Supplementation through Drinking Water on Pork Quality
نویسندگان
چکیده
Thirty-two pigs were used to determine the effect of age of pig and magnesium supplementation through drinking water on fresh and stored pork quality. Two groups were identified as fast or slow growers, 153 or 180 ± 0.4 days of age at 108 ± 0.6 kg BW. Pigs were harvested on the same day and pork quality measurements were conducted. The age of pig at market weight had no effect on display fluid loss, purge loss, or lipid oxidation of loins or hams. However, hams from older pigs had less surface exudate than younger pigs. Furthermore, loins and hams from older pigs were darker and hams tended to be redder during display storage than those from of younger pigs. Although, magnesium supplementation did not affect pork quality characteristics, pork from older pigs were darker and tended to be redder than from younger pigs.

Effects of pig age at market weight and magnesium supplementation through drinking water on pork quality.
Thirty-two halothane-negative pigs (109 +/- 0.6 kg of BW) were used to determine the effect of pig age at marketing (and thus growth rate), and magnesium supplementation through drinking water, on pork quality. Two initial groups of 50 pigs that differed by 30 +/- 2 d of age were fed diets to meet or exceed nutrient requirements beginning at 28 kg of BW. Sixteen average, representative pigs wer...

This study was carried out to evaluate the effects of Satureja khuzistanica essential oils (SKEO) on performance, serum metabolites and differential counts of white blood cells in broiler chickens. A total of 280 one-day-old straight-run Cobb 500 broiler chickens were allocated into seven treatment groups with four replicates of 10 birds each from day 1 to 42 of age. The birds were continuously...

This experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (Cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. The chicks were randomly distr...

The objective of this study was to investigate the effect of dietary supplementation of blood meal as a source of L-histidine, and the addition of magnesium (Mg) as a catalyst of carnosine synthetase for the carnosine and anserine concentrations of pig muscles (longissimus dorsi, LD and vastus intermedius, VI). A total of twenty-four pigs with an average body weight of 60.2±4.2 kg were randomly...
