Evaluation of impact of chelated mineral mixture formulation supplementation on milk quantity and milk quality parameters in lactating dairy cows under field conditions

The primary aim of the present study is to evaluate the effect of chelated organic mineral mixture “Him Chelate” (Developed by Himalaya Wellness Company) on milk production, fat percentage, solids not fat (SNF) and milk somatic cell counts in lactating dairy cows. A total of eight lactating dairy cows were randomly selected in one group (G) supplemented with HimChelate mixed with concentrate feed and water at a dose of 30 g/day/cow. The cows were used as their controls and thus, allocated to a control pretreatment period (baseline; 7 days), followed by a treatment period (30 days) and after the treatment period (7 days). The impact of HimChelate supplementation on milk production and quality parameters viz, fat and SNF percentages were before supplementation (baseline), during the supplementation period of HimChelate daily up to 4 weeksand after supplementation of HimChelate (1 week) were accessed to evaluate the efficacy of HimChelate. The mean milk yield in G on the baseline and during the treatment period, i.e., weeks 1, 2, 3 and 4, was 10.64±1.34 and 10.72±1.36, 10.76±1.35, 10.79±1.37 and 10.73±1.40, respectively. The sum milk yield was increased moderately in G during the treatment period compared with that on the baseline throughout the treatment period, i.e., 0.58 L (week 1), 0.93 L (week 2), 1.20 L (week 3) and 0.68 L (week 4). The impact of HimChelate on assessment parameters, such as milk yield, fat and SNF in dairy cows showed that mean milk yield (L) was increased by 1.03% following supplementation of HimChelate at 30 g (G) once daily per cow, respectively. Conversely, fat and SNF percentages were increased by 4.41% and 0.25% following the supplementation of HimChelate at 30 g(G). The supplementation of HimChelate 30 g once daily caused a slight reduction in milk somatic cell count (SCC) as early as day 3 (5100000 cells/mL). Conversely, the major reduction in milk SCC count was observed from day 9, i.e., 900000 cells/mL and maintained milk SCC of 300000 cells/mL from days 12 to 21. The findings of present research investigation depicted that the supplementation of HimChelate at the dose of 30 g/day/cow was better in terms of augmentation of milk production and improvement of milk quality parameters.
