No culling in Indonesia, says researcher
Results of the Research: Lokal Indonesian Chickens Resistent to Bird Flu
Bogor (Antara News) - the local Indonesian Chicken be classed as had the level resisten (resistance) was high enough towards the infection of the bird flu virus (avian influenza) compared to the other kind chicken in the world like the local China chicken, the local African chicken or the chicken broiler.
This conclusion was results of the DNA Puslit Biologi LIPI laboratory research of 331 samples of original chicken blood local the homeland that was gathered in 2007 through the method sequencing and PCR-RFLP.
The DNA analysis against our local chicken showed that the frequency allele A that resisten towards the AI virus revolving 0.35-0.89, said the Researcher the DNA Divisi Zoologi Puslit Biologi LIPI Lab M. Syamsul Arifin Zein in Cibinong Bogor, on Monday.
From 16 populasiB breed the local chicken that was researched, he explained, the Cemani chicken was that most resisten towards the AI virus, that is having the frequency allele A (genotip that resisten) to 0.88.
Afterwards the nonpedigreed chicken including that also was enough resisten, like the Lampung nonpedigreed chicken 0.72, the Banten nonpedigreed chicken 0.63, Kate's chicken 0.65 and that was most susceptible the AI virus was the cotton chicken 0.35.
This figure was far if compared with the local China chicken (East Asia) that the frequency allele A him in general only 0.22, or the local African chicken 0.44, now the local Indian chicken (South Asia) really resisten reached in general 0,64.
In the meantime the chicken of the kind race broiler (pedaging) really was susceptible to the AI virus with the frequency allele A only 0.22, but the chicken of the race of the layer kind really resisten that is reaching 0.92.
So the policy destroyed the chicken in a mass fashion to prevent the spreading of the AI virus uptil now being inexact, because this precisely destroyed the diversity of chicken genetics, including the actual chicken resisten towards the virus of AI. Chicken that resistent this was destroyed him because of being destroyed had by the policy, he said. According to Syamsul, this policy deadly the poultry farm industry and domestic food.
In fact from all breed the local chicken that around 32-35 breed could be researched with the analysis of PCR-RFCP easily whether this chicken from the kind that resisten or susceptible.
With knew resistent or susceptible him the chicken from the AI virus, then henceforth could be carried out by the genetic conflict chickens that only had the frequency allele A so that the descendants of the following local chicken to resisten, he said.
In the meantime, the researcher the DNA LIPI Lab other, Sri Sulandari, said, Indonesia was one of the three locations of the place of the forest chicken was domesticated the first time.
The data and results of the research of 23 countries, in the world, there were three places that to early of the domestication of the forest chicken, namely the domestication of the forest chicken in China to 6,000 before Masehi, the domestication of the forest chicken in India (2000 before Masehi), and the forest chicken in the Indonesian Archipelago, he said.
From three locations afterwards spread to various other places in the world that could be seen in the grouping in the genetic map.
He gave an example, the chicken in Europe and North Africa that was coming from India, while the Indonesian forest chicken spread to Madagascar, East Africa.

Comment: could resistent chickens still shed the virus?
