 Production of shell eggs enriched with n-3 fatty acids

Journal Title: IOSR Journal of Pharmacy (IOSRPHR) - Year 2015, Vol 5, Issue 8

Abstract

 Unsaturated long chain fatty acids (n-3 FAs) have been proposed in a human diet to reduce the risk of atherosclerosis and therefore the risk of stroke. N-3 FAs also play an important role in retinal and brain tissue development in the neonate. The main natural source of n-3 FA is marine fish. The aim of this work was to create shell egg enriched with n-3 FAs using natural golden marine algae (MA) as a supplement in hen’s diet. Three experiments were conducted: (1) hundred hens from the hybrid Lohmann Brown were fed with diet containing 1.27% MA; (2) hundred hens from the same hybrid were fed with diet containing 1.77% MA; (3) hundred hens were the control group. The duration of the experiments was 4 weeks. Slight enriching of the shell egg yolk at the both groups fed with diet containing MA happened after the end of the second week. The concentration of docosahexaenoic acid (DHA; C22:6, n=3) at the 1st experimental group was 90.3 mg/100 g of egg mass, and 112.1 mg/100 g of egg mass at the 2nd experimental group. The concentration of DHA at the control group was 54.5 mg/100 g of egg mass. After the 3 rd week the concentration of DHA at the 1st group increased to 201.2 mg/100 g of egg mass and to 304.9 mg/100 g of egg mass at the 2 ndgroup. At that  time the concentration of the DHA at the control group remained unchanged. At the end of the 4th week the concentration of DHA reached the maximum level: 224.5 mg/100 g of egg mass at the 1st group and 328.4 mg/ 100 g of egg mass at the 2nd group. The concentration of the DHA at the control group was 51.9 mg/100 g egg mass. It is interested to note that eicosapentaenoic acid (EPA; C20:5, n=3) appeared in low concentrations of 10- 15 mg/100g of egg mass at the end of the 4th week of the experiment at the 2nd experimental group.

Antifungal activity of Hyptis spicigera (Lamiaceae) extracts and essential oils of Cymbopogon citratus (Poaceae) and Cymbopogon giganteus against the growth of Aspergillus strains isolated in Burkina Faso

Abstract: Antifungal activity of local plant extracts on the growth of seven reference and local isolated strains of Aspergillus was tested. The extracts were composed of essential oils (E.O.) from Cymbopogon citratus, C...
