Impact of Lemongrass and Galangal as Feed Additives on
Performance of Lactating Barki Goats
A.M. Abd El Tawab,
Background: The current study was carried out to investigate addition of lemongrass or galangal to diet and its effect of productive
performance of lactating Barki goats. Materials and Methods: Thirty lactating Barki goats were divided into three groups (10 animals per
each treatment), first group was fed control diet without additives, consist of Egyptian clover hay, corn silage and concentrate feed
mixture (10:30:60% on DM basis, respectively) (Control); second group was fed control diet plus 4 g of lemongrass kg1 DM and the third
group was fed control diet plus 4 g galangal kg1 DM.Results: The results showed that adding galangal increased propionate
concentrations (p<0.05) compared with control (41.13, 37.75 and 39.46 mM for galangal, control and lemongrass, respectively); while,
there were no differences (p>0.05) between treatments in acetate and butyrate concentrations. Ammonia concentration was higher
(p<0.05) in lemongrass compared with other treatments (21.49, 15.92 and 15.91 mM for lemongrass, control and galangal, respectively).
Milk yield were significantly increased (p<0.05) by adding lemongrass or galangal to the diets (825 and 771 g day1 for lemongrass and
galangal) compared with control (652 g day1 ). Also, milk lactose content was significantly increased (p<0.05) in lemongrass compared
with control (44, 40 and 39 g kg1 for lemongrass, control and galangal, respectively). Conclusion: It could be concluded that adding
lemongrass or galangal the diet could enhance the performance of lactating Barki goat.
