Effect of preparations based on algae extract on the formation of selected biochemical parameters of blood and immune response of laying hens
2018
The large-scale poultry production has led to the search for new feed materials that can be used in this sector. Such a material may be algae, which contains many biologically active compounds from its biomass. The aim of the study was to determine the effect of preparations based on extract of Spirulina platensis algae on selected biochemical parameters of the blood of the studied birds. The tested parameters were total cholesterol, high density lipoprotein, low density lipoprotein, triglycerides, calcium, phosphorus, aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase. In addition, the effect of the extract used on the immune system of birds and the level of specific antibodies after vaccination with a combination vaccine was also checked. The obtained results showed the effect of the preparations on the activity of liver enzymes. Potential immunomodulatory properties of one of used preparations were also demonstrated.
