Altered serum magnesium level in non-descript broilers during heat stress

Abstract

This research conducted in non-descript broilers to explore the impact of heat stress on serum magnesium. During sampling process two hundred forty healthy broilers were examined in two ambiences which were moderate and hot humid. Total 120 non -descript broilers sampled in each ambience. Each and every group of one hundred twenty birds was again divided into 3 subgroups according to their age namely two weeks, four to six weeks and more than eight weeks. Each subgroup contains 40 non-descript broilers. Data were analyzed through IBM SPSS software by two-way ANOVA. During moderate ambience, overall mean value of serum magnesium was 0.85 ± 0.00 mmol L-1 irrespective of age group and the scale was between 0.83-0.87 mmol L-1. The overall mean value of serum magnesium during hot humid ambience was 0.55 ± 0.01 mmol L-1 irrespective of age and the scale was between 0.47-0.60 mmol L-1. The overall range was 0.47-0.87 mmol L-1. The results of present study in respect with serum magnesium level showed that heat stress create oxidative stress in broilers which can alter serum electrolytes level such as magnesium so the antioxidants supplementation suggested during both seasons to reduce the adverse impact of stress produced by free radicals.
