Calcium, Phosphorus, Sodium and Potassium Concentrations in Blood Serum of Yearling Goats Raised Semi-Intensively in Minna, North Central, Nigeria.

Abstract

The aim of this study is to evaluate the serum concentration levels of calcium,

phosphorus, sodium and potassium in yearling goats raised semi-intensively. 5ml

blood sample were obtained bi- weekly from the jugular vein of the yearling goats

and poured into test tubes not containing anti-coagulants from which serum was

obtained for electrolyte assay. The weight of the animals were also determined

bi-weekly. The mean calcium, phosphorus, sodium and potassium levels obtained

during the study ranges between 1.66±0.06 - 2.59±0.08; 12.71±0.57-140.29±2.57

and 3.33±0.06-4.79±0.26 mmol/L respectively. The result revealed that the levels

of sodium and potassium obtained from the experimental goats were within the

normal level required for the young growing goats. However, the levels of

calcium and phosphorus fall below required levels. There was a progressive

increase in the weight of the animals from week 2 to week 4; however, decrease

in weight gain was evidenced from week 6 to week 8. It is recommended that

supplementation of calcium and phosphorus minerals in form of free choice

mineral supplement which are generally considered for livestock that do not have

access to concentrates would seem most important for optimum productivity of

grazing goats in the study area.
