Effect of Peppermint and Rosemary Extractions on Ruminant In-vitro Digestibility
Advances in Animal and Veterinary Sciences
IntrOductIOn P eppermint, Mentha piperita or Mentha balsamea wild, and rosemary, Rosmarinus officinalis, are evergreen perennial shrub, were widely used in medicinal products, with large medical bioactive compounds, like menthol, menthone, isomenthone, eriocitrin, phenolic compounds (Sokovic et al., 2009; Hussain et al., 2010) . In addition, leaves and oil of mint family used in food as flavorings and food seasoning, to contain volatile aromatic oils. These plants with fibrous roots are
... s roots are cultivated in many drought areas with lack of water for long periods, so, it's important plants in subtropical climate. Civilizations of Mesopotamia and Nile valley were the first of using in medicine. These phytogenic additives and phytochemicals contain camphor, salicylate, kaifik, yurosolic and butylonic acid, antioxidants such as karnosic acid, rosmarinic acid and carnosol . During grazing, animals' ad-libitum feeding peppermint and rosemary or others medical plants, there for, ruminant exposed to many phenolic compounds, like tannins, lignin and other metabolites like saponins. These aromatic plants have essential oils (derived components) which aren't poison (FDA, 2004) , active against many gram-positive or negative bacteria by interfering with permeability of cell membrane causing intracellular leakage (Trombetta et al., 2005) , in order to the possibility of adaptation of rumen microflora, bioactive compounds in peppermint or rosemary suppressed the growth human viruses, so, it may have negative effect against rumen microorganisms. Thus, the aim of the following research was to determine the impact of peppermint and rosemary dried leaves, watery, alcoholic and organic extractions in rumen digestibility. research Article Abstract | The objective of this study was to evaluate the effects of organic, watery and alcoholic extractions of peppermint and rosemary leaves on in-vitro ruminant digestibility. Three tubes for each treatment with three blank were used and the mean value was evaluated statistically. It was found that after 48 hours of incubations, addition of 200mg of organic extractions for peppermint and rosemary significantly decreased dry matter digestibility (DMD) in contrast with control, by 83.41%, 81.99% and 86.21% respectively, and organic matter digestibility (OMD), 85.23%, 84.27% and 90.19% respectively, while there were no significances for adding 200mg of dried leaves, watery and alcoholic extractions. Results suggested that the addition of peppermint or rosemary as a dried herbage or fresh to ruminants' diet didn't alter the rumen digestibility with a high content of crude protein. citation | Tawfeeq JA, Al-Omrani HA, Shaker RM, Hamza ZR, Abbas SF, Jabbar RH (2019).
