Appraisal of iron accumulation in soil, forages, and blood plasma of sheep and goats: a case study in different districts of Punjab, Pakistan

2021

Minerals are essential for ruminants affecting significantly the production of grazing livestock. Iron level in forages, soil, and blood plasma of the small ruminants (goat and sheep) was investigated in three districts of Punjab. Atomic absorption spectrophotometer was used to determine the concentration of iron in collected samples. The results revealed that the mean Fe concentrations in soil of districts Sargodha, Mianwali, and Bhakhar were significantly varied and ranged from 21.85 to 23.78, 28.45 to 31.2, and 18.079 to 24.33 mg/kg, respectively. The Fe level in soil of Mianwali significantly varied and was higher than Sargodha and Bhakkar. The mean Fe concentration in forages which were used for feeding purpose were significantly varied and found between 10.95–14.49, 23.63–25.65, and 6.616–9.45 mg/kg for Sargodha, Mianwali, and Bhakhar, respectively. The mean Fe concentrations in blood plasma of goat which consumed the contaminated forages were 8.5026–11.763 mg/L in district Sargodha, 19.77–20.19 mg/L in Mianwali, and 5.508–5.858mg/L in Bhakkar. In blood plasma of sheep, the residual levels of Fe in districts Sargodha, Mianwali, and Bhakhar were ranged from 9.987 to 12.455, 15.8 to 19.785, and 3.425 to 6.383 mg/L, respectively. This study provides the data of metals effected by different sites and also their mobility from low to higher trophic level which enables us to study the iron toxicity in different trophic levels, and we recommend different safe limits and treatment in case of low and high metal profile.
