The impact of physiological condition on calcium, phosphorus and magnesium levels in sheep blood serum

Stojković J., Ilić Z., Milenković M., Đoković R., Jašović B.

A large number of sheep, especially the ones that spend the majority of time on pastures, is being fed with the meals which do not contain all the neccessary mineral substances. The level of calcium, phosphorus and magnesium on natural pastures is too low considering the neccessities of sheep. So, the irregularities in sheep feeding occur because of the absence of other food sources. These irregularities range from the acute mineral deficite or illness, to the mild temporary forms which can hardly be diagnosed, but they affect the level of production. The contents of calcium, phosphorus and magnesium in sheep blood serum are given in this paper, as some of the indicators of the need for supplementation of these substances. The average calcium level in the blood serum of the control group was 2.61 mmol/l, phosphorus level was 1.04 mmol/l and magnesium level was 1.31 mmol/l. The average calcium level in the blood serum of the tested group was 2.33 mmol/l, phosphorus level was 0.92 mmol/l and magnesium level was 1.37 mmol/l.
