Role of Caraway, Fennel and Melissa Addition on Productive Performance of Lactating Frisian Cows.

Background and Objective: The use of aromatic and herbal plants as a feed additive became a new trend in feeding dairy cows to enhance animal productivity. This study was conducted to evaluate the effect of adding some herbal and aromatic plants (Melissa, Fennel and Caraway) at 0.7% of total DM of rations.
Materials and Methods: Three herbal plants were evaluated in this study (melissa, fennel and caraway) by using thirteen Holstein Friesian cows. Cows were in 3rd and 5th lactation seasons were used as one experimental group by swing over design in lactation experiment (control then T1 then T2 then T3 then control). Nutrients digestibility, milk production, milk composition and blood constituents were determined.
Results: Data indicated that nutrients digestibility and nutritive value were improved with herbal plants addition, especially with caraway treatment which recorded significantly (p>0.05) the highest values. In the same trend, Actual milk yield, 4% FCM and fat content were significantly (p>0.05) increased when cows fed rations supplemented with fennel and caraway. The addition of melissa decreased the concentration of Total Saturated Fatty Acids (TSFA) in the milk. Normal ranges for blood parameters with no negative impact on animal health were observed with experimental rations.
Conclusion: It could be concluded that caraway addition at 0.7% of the total dry matter of dairy rations, has a great potential to improve animal productivity and enhance the quality of milk fatty acids profile.
