The Effect of Various Dietary Magnesium Levels on Growth Performance and Carcass Yield of Broiler Chickens

Popis výsledku v původním jazyce

The aim of this study was to evaluate the effect of various magnesium doses in the diet on a growth performance of broiler chickens and carcass yield. Magnesium (Mg) was added to the feed mixtures in MgSO4 form. The basic feed ration contained 1.71 g of Mg per 1 kilogram dry matter. The control group received the feed with added 2.5 g/kg MgSO4. The feeds for two experimental groups contained the addition of 1 g/kg MgSO4 and 7.5 g/kg MgSO4 (groups Exp1; Exp2; respectively). In the trial, feed intake and live weight of chickens were monitored. The experiment was conducted from day 11 to day 35 of chickens age. Experimental animals were weighed and slaughtered at the end of the trial. Feathers were removed and chickens were eviscerated. Carcass yield was calculated. Selected chickens were deboned and breast muscle and leg muscle were weighed. These parameters were expressed by the percentage of live weight of breast and leg muscle. The total magnesium levels in experimental groups (1.91 g/kg diet and 3.21 g/kg diet) had a negative effect on slaughter weight compared to the control group (2.21 g/kg Mg). This trend was noticeable in evaluation of carcass yield, as well. The differences between groups were statistically non-significant (P > 0.05). Statistically significant difference (P < 0.05) was recorded between control group (2.21 g/kg Mg of the diet) and experimental group (3.21 g/kg Mg of the diet) on deboned thigh muscle. Tested magnesium levels had non-significant effect to chicken production parameters but had a positive effect on carcass yield (thigh muscle).
