ABSTRACT
The objective of this experiment was to investigate the potential influence of microweed Spirulina platensis on the the milk production and serological parameters in Lithuanian Black-and-White cows. Twenty cows on IIIII lactation at 60-120 days from the beginning of lactation were divided randomly into two groups each of 10 cows - control and experimental groups, respectively. Two experimental diets were formaluted based on forage (control) and on forage with 2 g/day per cow biomass of fresh weed Spirulina platensis. During 60 days forage plus weed fed cows exhibited an 7.6% or 136 kg increment in average amount of milk compared to the cows on forage diet. In cows on weed supplementation the average amount of milk fat increased on 17.6-25.0 % (P<0.05), the average milk protein on 9.7% (P<0.05) and amount of lactose on 11.7% (P<0.001) compared to the controls. In addition, diet supplementation with Sprirulina platensis by 29.1% reduced the amount of somatic cells (SCC) in milk compared to control group. Further, in microweed-fed cows mean amount of haemoglobin increased on 8.9% (P<0.05) and erythrocytes on 13.1% (P<0.05) compared to the control group, respectively. These results demonstrate that inclusion of microweed Spirulina platensis in the diet leads to increment of milk production, stimulates hemopoesis and non-specific resistancy of organism of milking cows.
