The effect of feeding supplementation on the nutritional characteristics of milk and cheese was studied in dairy sheep grazing on low mountain dry-grasslands during summer in typical sub-Mediterranean conditions of aridity. The control group (CG) of 25 sheep grazed on grass, while the experimental group (EG) of 25 sheep grazed on grass and received...
Article
Selenium (Se) is an essential element present in milk as seleno-amino acids and seleno-proteins. To perform an accurate seleno-amino acid analysis, a complete hydrolysis of proteins is necessary. Microwave-assisted acid hydrolysis (MAAH) can be used; however, some variables must be optimised to avoid incomplete hydrolysis and oxidation. Multivariat...

Lamb meat hygiene and oxidation were considered in two groups of animals fed a diet with and without a mix of dill (Aneto graveolens L.), cinnamon bark (Cinnamomum Zeylanicum Blume) and eucalyptus (Eucalyptus globulus Labill.) essential oils. After 7 days of storage, a significant difference was observed on the Total Viable Count (TVC) of the meat...
Article
Bitter vetch (Vicia ervilia (L.) Willd.), a grain legume crop well adapted in marginal soils, has mainly been used for animal feed. Nowadays, bitter vetch seeds in feed formulations are replaced by other protein sources such as soybean meal. However, in the context of sustainable economic development, it may be beneficial to enhance the cultivation...

Ruminant livestock systems contribute significantly to emission of methane, a potent greenhouse gas as they waste a portion of the ingested energy (2–15%) as methane and a large proportion (75–95%) of the ingested nitrogen as ammonia. Recently, numerous researches have been conducted to evaluate plant secondary metabolites, including essential oils...
Article
Various essential oils (EO) have been individually evaluated to mitigate methane and ammonia production by rumen microbiota. Interactions between EO can affect their potency but such interactions largely remain unexplored. In the present study, EO from oregano, rosemary, Ceylon cinnamon, cinnamon leaves, cinnamon bark, dill seeds, and eucalyptus we...
