Productivity diversity of Sensi 1 Agrinak chicken crossed with KUB Chicken

Abstract

Bali Island has been a tourist destination, always lacking in the supply of native
chicken, both chicks and ready to cut. For that, Bali Assesment Institute Of Agriculture
Technology (BPTP Bali) took the initiative to develop superior native chicken breeding to
overcome the existing gaps. KUB Chicken and Sensi 1 Agrinak are superior chicken produced by
Agency Animal Research Ciawi Bogor. KUB chicken, which stands for superior native chicken
from the Indonesian Agency for Agricultural Research and Development, is the result of selection
of native chickens in Indonesia for female line and Sensi 1 Agrinak, which are 6 generations from
male line. Sensi 1 Agrinak (Male line) with KUB (Female line) is then crossed to produce native
chicken chicks that have superiority in both egg and meat production. The study was conducted in
Jehem Village, Bangli Regency. Using 300 KUB chickens (male line) and 80 tails Sensi 1 Agrinak
(female line). Maintenance is carried out in a letter enclosure between males and females mixed to
facilitate marriage among them. The feed given is chicken feed which is producing with a
composition of 40% corn, 35% bran and 25% concentrate. The results of the study show male
weight averages 1,718 grams/head with a range of 1,595 - 1,830 grams/head, while females (KUB)
average 1,233 grams/tail with a range of 1,210 - 1,420 grams/head. Daily egg productivity
(Henday) reaches 45% with an average egg weight of 44,81 g/grain with a range of 32-50 g/grain.
The egg fertility produced reached 83.67% with the number of eggs hatching 71.84% and those
that hatched in normal conditions reached 93.89%. Mortality is still high at 17.93%, with an
average weight of newly hatched chicks (DOC) of 32.23 g/head.
