Spirulina supplementation during the transition period by grazing dairy cattle at tropical highland conditions

The objective of this experiment was to evaluate the effects of spirulina supplementation on oxidative stress, immunity, and productive performance during the transition period by grazing dairy cattle. Thirty multiparous gestating cows with an initial body weight (BW = 544 ± 57 kg) were enrolled in this experiment and were stratified by expected calving date. Cows were randomly assigned to one of the three experimental groups: (1) control, no supplementation of spirulina; (2) spirulina-15 (15 g/day of spirulina); and (3) spirulina-30 (30 g/day of spirulina). Body weight and body condition score (BCS) were recorded and blood samples were collected at − 21, 1, and 14 days, relative to calving. The day of parturition, colostrum and blood samples from calves were collected to measure IgG concentrations. After parturition milk yield, milk components and somatic cell count were monitored. Body weight, BW loss, BCS, and total antioxidant capacity were not affected by spirulina supplementation (P > 0.23) at any time point measured. Milk yield, milk components, and somatic cell count were not altered by treatment (P > 0.13). Results from this experiment suggest neither positive nor negative effects of spirulina supplementation on oxidative stress and productive performance during the transition period.
