the aim of this research was to study the in vitro effect of lavandula officinalis (leo) and origanum vulgare (oeo) essential oils on rumen fermentation using a concentrate type substrate (cts) and roughage type substrate (rts). six mehraban ewes were divided into 2 groups and fed a concentrate type or roughage type diet, and used as rumen fluid donors. each essential oil (eo) was evaluated sep...

Type 1 diabetes (T1D), an autoimmune inflammatory disorder, develops as a consequence of pancreatic β-cell destruction and results in hyperglycaemia. Since current T1D therapy mainly involves insulin replacement, the aim of the present study was to evaluate the therapeutic potential of Origanum vulgare L. ssp. hirtum (Greek oregano) leaf extract rich in biophenols for the treatment of T1D. The ...

This experiment investigated the effects of dietary supplementation of Origanum vulgare L. leaf material (OR) on rumen fermentation, production, and milk fatty acid composition in dairy cows. The experimental design was a replicated 4 × 4 Latin square with 8 rumen-cannulated Holstein cows and 20-d experimental periods. Treatments were control (no OR supplementation), 250 g/cow per day OR (LOR),...

BACKGROUND: Bacterial resistance to antibiotics is a crucial public health problem. Essential oils (EOs) possess antimicrobial effects and have been screened as potential natural antimicrobial compounds. OBJECTIVES: This study was conducted to compare the effects of Eugenia caryophyllus (clove) and Origanum compactum (oregano) EOs on the growth of Staphylococcus aureus and the expression of the...

The objective of our work was the valorisation four aromatic plants growing spontaneously in Kabylia (Algeria) by evaluation their insecticidal activity against black bean aphid Aphis fabae Scopoli, 1763. These are oregano, thyme, rosemary and lavender. were subjected to a phytochemical analysis determine secondary metabolites composition. results obtained showed that extracts toxic A. can sign...

A procedural modification of the AOAC Official Method for extracting light filth from ground oregano and ground marjoram was tested in an intralaboratory study. The modified method specifies isopropanol defatting, 975.49A(a), rather than chloroform-isopropanol defatting, 975.49A(b), followed by direct flotation as directed in AOAC Official Method, 975.49B(b). The modified method provided compar...

This study aimed to determine the changes in quality of sous vide meagre (Argyrosomus regius) fillets that have been treated with oregano and rosemary extracts during cold storage (4±1 °C). Saturated fatty acids, monounsaturated polyunsaturated acids dominant fish were found be palmitic acid, oleic linoleic respectively. pH values fluctuated samples. It was determined total volatile basic nitro...
