Bobot Akhir, Persentase Karkas Dan Lemak Abdominal Ayam Broiler Yang Dipanen Pada Umur Yang Berbeda

Penelitian ini bertujuan untuk mengetahui bobot akhir, persentase karkas dan lemak abdominal ayam broiler yang dipanen pada umur yang berbeda sehingga dapat menyesuaikan dengan permintaan pasar. Penelitian menggunakan metode experimental dengan Rancangan Acak Lengkap (RAL). Pemanenan dimulai dari umur 21 hari sampai 42 hari dengan interval 3 hari, sehingga terdapat 8 perlakuan saat umur panen (P1=Umur Panen 21 hari, P2=Umur Panen 24 hari, P3=Umur Panen 27 hari, P4=Umur Panen 30 hari,P5=Umur Panen 33 hari, P6=Umur Panen 36 hari, P7=Umur Panen 39 hari dan P8=Umur Panen 42 hari) dengan tiga ulangan. Ayam yang digunakan yaitu strain Cobb sebanyak 120 ekor. Peubah yang diamati meliputi : bobot akhir, persentase karkas dan lemak abdominal. Hasil Penelitian diperoleh bahwa pemanenan ayam broiler ukuran kecil (± 1 kg) sebaiknya pada umur 21 hari, ukuran sedang (± 1,6 kg) pada umur 30 hari dan ukuran besar (± 2,2 kg) pada umur 39 hari. Persentase karkas tertinggi (75,45%) diperoleh pada pemanenan umur 33 hari dan persentase lemak abdominal terendah (2,24%) diperoleh pada umur panen 21 hari.

The aim of the research is to investigate the influence of different yield age of broilers on final weight, carcass percentage and abdominal fat content. Complete Randomized Design was used as experimental method of the research. Yielding was initially started at the age of 21d until 42d with 3d of interval, thus it had eight different treatments based on yielding age (T1=21d; T2=24d; T3=27d; T4=30d; T5=33d; T6=36d; T7=38d; T8=42d). Each of treatment had three replications. 120 Cobb strain broiler were used in this study while observed variable measurements were final weight, carcass percentage, and abdominal fat content. The result showed that smaller weight of broiler (±1 kg) was preferably yielded at 21d, moderate weight (±1.6 kg) at 30d, and large weight (±2.2 kg) at 39d. The yielding age of 33d (T5) had the highest percentage of carcass (75.45%) while the yielding age of 21d (T1) had the lowest abdominal fat content.
