The plant grows in denseclumps up to ２ meters in diameter and has leaves up to １ meter long . The fresh stalks and leaves have a clean lemon like odorbecause they contain an essential oil , which is also present in lemon peel . Lemon grass is a perennial tufted grass with long ,sharp‐edged blades . It grows in dense clumps in tropical or subtropical climates . In traditional medicine , lemon grass is usedfor the cure of some infectious illnesses and fever . The benefits derived from lemon grass are that it clears confusion , lessensstress and reduces mental fatigue . Other medicinal properties of lemongrass include its use as an antiseptic agent , astringentbactericide , insecticide and fungicide . It can be used as an antiseptic wash or as a compress on skin infections such as ringwormand infected sores . It can also be taken as an anti‐oxidant as well as to assist the process of digestion . As lemon grass can beeasily produced in large quantity whether it can be used to feed dairy cow and in the process improve milk flavor or cow healthmerits research .Material and methods Lemon grass was dried and grinded to powder . Four dairy cows were chosen and randomly divided into ２groups : a treatment group and a control group . The treatment group was fed a ration containing １ .５ kg powder of lemongrassper day and the control group fed the same ration except without lemon grass . The feed experiment lasted for ２０ days . Threedays after feeding with lemongrass powder , the milk was sampled every day , and the milk quantity and quality were checkedand analyzed , and the anti‐oxidation of the blood determined .Results Fed with lemon grass , there was no significant influence on milk production , and no abnormality was found in the dairycows . The results indicated that by adding lemon grass hay １ .５kg/ d per cow , the milk fat , milk protein , lactose , dry matterand non‐fat dry matter content changed little and there was no significant difference between the treatment and control ( Table１ ) . Fed with lemon grass , the cow blood antioxidant capacity improved ,serum SOD and GSH‐Px activity significantly increased( P ＜ ０ .０５ ) and MDA decreased ( Table ２ ) . By HPLC , citral can be detected in milk ; the concentration of citral was ０ .２１１μgkg‐１ . Lemon grass has rich aromas and so can also reduce the bad odor in cowsheds .Table 1 Ef f ect o f adding lemongrass on milk quality .( ％ )Group Dry matter Milk fat Lactoprotein Lactose Non‐fat dry matterControl １１ .８２ ３ .６９ ３ .０５ ４ .２６ ７ .９５Treatment １２ .０５ ３ .５２ ３ .２１ ４ .５９ ８ .５８Table 2 Ef f ect o f f eeding lemongrass on the anti‐oxidation o f milk cow blood serum .Group SOD( U爛 ml‐１ ) GSH‐PX( U爛 ml‐１ ) MDA( nmol爛 ml‐１ )Control １０９ .２７ １７５ .６２ ４ .２８Treatment １２１ .１４ １８７ .８６ ３ .９４Conclusions Lemon grass can be used in the diet of dairy cow without affecting milk production . It can improve the health ofdairy cows . Lemon grass contains rich natural citral which can be transferred to milk and improve the milk flavor . Aroma ofhigh concentration citral can also reduce the bad odor in cowshedsReferencesAdegoke G O , Odesola B A .
