Efektivitas Penambahan Minyak Sereh (Cymbopogon nardus) dan Selenium Organik pada Ransum terhadap Profil Darah dan Diferensiasi Leukosit Ayam Broiler

Abstract

Penggunaan Antibiotic Growth Promotors meninggalkan residu antibiotik pada produk ternak yang dapat membahayakan kesehatan manusia, sehingga perlu alternatif pengganti seperti minyak esensial sereh (Cymbopogon nardus) dan Selenium organik. Penelitian ini bertujuan mengevaluasi efektivitas penambahan minyak sereh dan selenium pada pakan terhadap profil darah dan diferensiasi leukosit ayam broiler. Penelitian menggunakan Rancangan Acak Lengkap (RAL) Faktorial dengan 2 level suplementasi selenium (0 ppm dan 0,4 ppm) dan 3 level suplementasi minyak sereh wangi (0 mL kg-1, 2 mL kg-1, dan 4 mL kg-1). Hasil penelitian menunjukkan bahwa penggunaan minyak esensial sereh nyata (P<0,05) menurunkan leukosit. Terdapat interaksi (P<0,05) terhadap level hematokrit. Perlakuan minyak sereh dan mineral Se tidak berpengaruh (P>0,05) terhadap diferensiasi leukosit. Simpulan penelitian ini adalah penggunaan 4 mL kg-1 minyak sereh menurunkan leukosit serta pemberian 2 mL kg-1 minyak sereh ditambah 0,4 ppm Se menurunkan level hematokrit.

The use of Antibiotic Growth Promoters (AGPs), which can leave antibiotic residues harmful to human health, can be addressed with citronella essential oil (Cymbopogon nardus) and organic selenium as alternatives. This study aimed to evaluate the effectiveness of adding citronella oil and selenium at different concentrations in feed on blood profiles and leukocyte differentiation in broiler chickens. A factorial Completely Randomized Design (CRD) was used, consisting of two levels of selenium supplementation (0 ppm, 0,4 ppm) and three levels of citronella essential oil supplementation (0 mL kg-1, 2 mL kg-1, 4 mL kg-1). The results showed that citronella essential oil significantly (P<0.05) reduced leukocyte levels. There was a significant interaction (P<0.05) affecting hematocrit levels. However, the combination of citronella essential oil and selenium did not significantly (P>0.05) affect leukocyte differentiation. In conclusion, the administration of 4 mL kg-1 of citronella essential oil reduced leukocyte levels, while 2 mL kg-1 of citronella essential oil combined with 0,4 ppm selenium lowered hematocrit levels.
