Impact of net charge of mineral supplements onhaematological profile in dairy cows

Abstract

Study evaluated changes in haematological profile for dairy cows when supplemented with essential cation (T1), anion (T2) or both (T3) and compared with control without any mineral supplements (MS). Basal diet consisted fresh para grass, ragi straw and concentrate supplement. Net charge of the MS of T1, T2 and T3 was +0.87, –1.55 and –0.64, respectively. DM and OM intake were comparable between CG and TGs. RBC (p< 0.10), HCT (p< 0.02) and RDW (p< 0.10) were significantly higher in T3 but comparable between CG, T1 and T2. PLT (p< 0.06) and PCT (p< 0.10) were higher in T1 and T2 and least in CG. Study concluded that net ion charge of MS either positive or negative had no effect on haematological profile in dairy cows. Impact was better when MS contained both essential cation and anion minerals.
