| Abstract (English): |
IPB University local chicken which named IPB-D3 is a prospective male line obtained from the chicken selection program IPB-D1. The establishment of IPB-D3 chickens aims to produce local chickens with fast growth weight. This research aims to evaluate the performance of local chickens from IPB-D3 Generation 4 (G4) and its heritability values. The observed samples include 10 males and 30 females of IPB-D3 chickens of Generation 3 (G3) aged 21-40 weeks as parent and 100 Day Old Chickens (DOC) IPB-D3 G4 up to 12 weeks old. The results obtained that IPB-D3 G4 chickens show an average body weight for males 1021.44 g and females around 648.33 g at the age of 12 weeks. The feed given to IPB-D3 G4 chickens is the same as the parents, namely it has nutrients below commercial feed because the feed given uses a mixture of local feed which are bran and corn which already used in Sinar Harapan Farm Sukabumi. Weight gain is the change in body weight that occurs over a specific period, and the weight gain of IPB-D3 G4 chickens is relatively fast, especially from the 2nd to the 3rd month, with a weight gain rate reaching 406.27 g. Growth rate from IPB-D3 G4 chickens experiences a slowdown at the age of 2 months and falls below their optimal growth rate. Another aspect to report is the mortality rate of IPB-D3 G4 chickens, which is quite high at the DOC and female age due to environmental conditions and disease attacks. However, the mortality rate decreases with the increasing age of the chickens, and no deaths are found in 12 weeks old male chickens. The heritability value of body weight in IPB-D3 G4 chickens is high at the age of 4 weeks and can be used as a basis for selection based on body weight. [ABSTRACT FROM AUTHOR] |

Ayam lokal institute pertanian bogor yang diberi nama IPB-D3 merupakan ayam calon galur jantan yang diperoleh dari program seleksi ayam IPB-D1. Pendirian ayam IPB-D3 untuk menghasilkan ayam lokal IPB dengan tujuan agar pertumbuhannya lebih cepat. Penelitian ini bertujuan untuk mengevaluasi performa ayam lokal IPB-D3 Generasi 4 (G4) dan nilai heritabilitasnya. Sampel yang diamati adalah 10 ekor pejantan dan 30 ekor betina ayam IPB-D3 Generasi 3 (G3) umur 21-40 minggu sebagai induk dan 100 ekor DOC (Day Old Chicken) hingga berumur 12 minggu. Hasil yang diperoleh ayam IPB-D3 G4 memiliki rata-rata bobot badan jantan 1021.44 g dan betina 684.33 g pada umur 12 minggu. Pakan yang diberikan pada ayam IPB-D3 G4 sama dengan indukannya yaitu memiliki nutrisi dibawah pakan komersial karena pakan yang diberikan menggunakan campuran pakan lokal yakni dedak dan jagung yang telah digunakan di Sinar Harapan Farm Sukabumi. Pertambahan bobot merupakan perubahan bobot badan yang terjadi dari waktu ke waktu tertentu, pertambahan bobot badan ayam IPB-D3 G4 tergolong pesat karena di bulan ke-2 hingga bulan ke-3 tingkat pertambahan bobot mencapai 406.27 g. Laju pertumbuhan ayam IPB-D3 G4 memiliki perlambatan pada umur 2 bulan karena dibawah laju pertumbuhan optimal. Hal lain yang dapat dilaporkan adalah tingkat mortalitas pada ayam IPB-D3 G4 cukup besar pada umur DOC dan betina yang disebabkan kondisi lingkungan dan serangan penyakit namun, tingkat mortalitas tersebut semakin bertambah kecil seiring umur ayam bertambah, bahkan pada ayam jantan umur 12 minggu tidak ditemukan kematian sama sekali. Nilai heritabilitas bobot badan pada ayam IPB-D3 G4 memiliki hasil yang tinggi pada umur 4 minggu dan dapat dijadikan dasar seleksi berdasarkan bobot badan tersebut. [ABSTRACT FROM AUTHOR] |
