Abstract


ABSTRACT

The study aimed to determine the effect of different lighting duration and feeding portion in broiler chickens on lymphocytes heterophile ratio (H / L) and bursa fabrisius relative weights and daily weight gain (DWG). Completely randomized design of split plot 2 x 3 arrangement was used in this research. Each treatment was replicated 5 times. Lighting duration as main plot and the sub plot was feeding portion. Twenty chickens were used as a control group and to distinguish between the treatment and the control group, was used. Parameters observed include H/L ratio, bursa fabrisius relative weight, DWG. Day old chick strain CP 707 as many as 320 heads, commercial rations and drinking water, medicines and vitamins. The results showed that there was no interaction (P> 0.05) between feeding portion and different lighting duration on H/L ratio, bursa fabrisius relative weight and daily body weight gain in broiler chickens. Old lighting real erpenaruh to value H / L ratio, bursa fabrisius relative weight and DWG. All parameter observed were significantly better than the control group. The conclusion was that intermittent lighting yielded H/L ratio, and the bursa fabrisius relative weight and DWG.

Keywords: broilers chicken; feeding portion; lighting duration; heterophile lymphocyte ratio; bursa fabrisius.

ABSTRAK

Penelitian bertujuan untuk mengetahui pengaruh kombinasi pemberian porsi ransum dan lama pencahayaan berbeda pada ayam broiler terhadap daya tahan tubuh berdasarkan rasio heterofil limfosit (H/L) dan bobot relatif bursa fabrisius dan pertambahan bobot badan harian (PBBH). Rancangan acak lengkap (RAL) split plot 2 x 3 digunakan dalam penelitian ini dan setiap perlakuan diulang 5 kali. Lama pencahayaan sebagai main plot dan porsi ransum sebagai sub plot.. Dua puluh ekor anak ayam disediakan sebagai kontrol dan untuk membedakan antara perlakuan terhadap kontrol digunakan t-test. Parameter yang diamati meliputi rasio H/L, bobot relatif bursa fabrisius, pertumbuhan bobot badan harian (PBBH). Materi yang digunakan adalah ayam broiler day old chick (DOC) strain CP 707 sebanyak 320 ekor, ransum komersial dan air minum, obat dan vitamin. Hasil penelitian menunjukkan bahwa tidak ada interaksi (P>0,05) antara porsi ransum dan lama pencahayaan berbeda terhadap rasio H/L, bobot relatif bursa fabrisius dan pertambahan bobot badan harian pada ayam broiler. Semua parameter yang diamati secara signifikan lebih baik daripada kelompok control. Kesimpulan bahwa pencahayaan berselang menghasilkan rasio H/L, bobot relative bursa fabrisius dan PBBH lebih baik.

Kata Kunci : Ayam broiler; porsi ransum; lama pencahayaan; rasio heterofil limfosit; bursa fabrisius.
