The Performance of Broilers Given Eugenol of Clove Leaf Essential Oil as a Feed Additive

Abstract

Clove (Syzygium aromaticum L.) leaf extraction can produce 2-4% essential oil, containing 70-90% eugenol. Clove essential oil has biological activities, such as antibacterial, antifungal, insecticidal and antioxidant properties, and is used traditionally as a savoring agent and antimicrobial material in food. It becomes the basis for this research on the use of eugenol of clove leaf essential oil as a feed additive for broilers. Experimental treatments consisted of E0 (without the use of eugenol), E1 (0.5% eugenol in feed), E2 (1% eugenol in feed), and E3 (1.5% eugenol in feed). The addition of 0.5 to 1.5% eugenol in feed significantly reduced feed intake compared to the control, in which the higher the use of eugenol in feed was, the lower the feed intake would be. The addition of 0.5-1% eugenol of clove leaf essential oil numerically increased body weight gain of broilers, but not significantly different between the three treatments, while the addition of 1.5% eugenol significantly decreased body weight gain compared to the other three treatments. The addition of 1% eugenol in feed significantly increased the final body weight compared to the control, but not significantly different from the addition of 0.5% eugenol, while the addition of 1.5% eugenol significantly decreased the final body weight compared to other treatments. The addition of 0.5-1.5% eugenol in feed significantly reduced feed conversion compared to control, but not significantly different between the three treatments. The addition of 1% eugenol of clove leaf essential oil in feed provided optimum body weight gain and final body weight for broilers at 6 weeks of age of 2035.00 ± 66.52 g/chicken and 2185.00 ± 66.52g/chicken, respectively with feed conversion of 1.61 ± 0.06.

The Effect of Encapsulated Propyl Propane Thiosulfonate (PTSO) on Apparent Ileal Digestibility and Productive Performance in Broiler Chickens

“…Moreover, this effect is not exclusive for garlic and its products. Tahir, et al [ 53 ] observed that using incremental doses of another phytochemical, eugenol, in broiler feed, affected the palatability, decreasing the ADFI while raising the inclusion of eugenol. Regarding to ION birds, our data suggests that it has no significant effect on performance.…”

Kecernaan Protein dan Lemak dari Penggunaan Minyak Atsiri Daun Cengkeh sebagai Sumber Fitobiotik dalam Pakan Ayam Ras Jantan

“…Minyak cengkeh memiliki kandungan antioksidan yang lebih tinggi dibadingkan dengan kandungan antioksidan yang terdapat pada lemon, anggur, dan ketumbar (Musta dan Nurliana, 2019). Menurut Tahir et al (2019) bahwa eugenol memiliki sifat anti mikroba dan anti oksidan yang dapat meningkatkan pertumbuhan ternak. Selain itu, daun cengkeh dapat menghasilkan 2-4% minyak atsiri dengan kadar 70-90%.…”

“…Tingginya nilai daya cerna pada penelitian ini diduga disebabkan pemberian minyak atsiri daun cengkeh yang tinggi. (Tahir et al, 2019) melaporkan bahwa dengan menambahkan 0,5-1% eugenol minyak atsiri daun cengkeh dalam pakan dapat meningkatkan daya cerna pakan, sehingga kebutuhan untuk pertumbuhan terpenuhi walaupun asupan pakan cenderung menurun; semakin tinggi penambahan minyak atsiri daun cengkeh dalam pakan, maka semakin rendah populasi Salmonella sp. dan Esherechia coli dalam saluran pencernaan yang berdampak pada meningkatnya kecernaan nutrisi pakan.…”

“…. Tingginya daya cerna protein dalam penelitian ini sesuai dengan pernyataanTahir et al (2019) bahwa penambahan minyak atsiri daun cengkeh 6,27-18,82 g/kg pakan dapat meningkatkan kecernaan protein.…”

Immune Organs and Growth Performance of Male Laying Hens With Use of Eugenol Clove Leaf Oil as a Substitute of Antibiotic in Feed

“…Eugenol content of clove leaf oil is 79.72% and antioxidant is 42.26 ppm. The higher the eugenol content of clove leaf oil, the higher the antioxidant content (Tahir, et al 2019. Razafimamonjison, et al( 2015 stated that the smell of clove leaf is caused by the content of eugenol which is the main compound (72-90%) and functions as an antiseptic and anesthetic.…”
