Professor of IPB University: Safe Chicken Eggs in Raw Consumption

Broiler chicken eggs can be contaminated with germs since in the stomach of the mother. If the mother is exposed to salmonella plorum, the chicken will get sick and die. But if salmonella enteritis, chicken is not sick but germs can nest in the reproductive organs, stick to the yolks and egg whites and carry over when the eggs come out of the chicken's body.

"Different from native chickens (local chickens and native chickens). He has the ability to eliminate germs (especially salmonella) because of his amazing immune cells, so that there are no salmonella findings in native chicken eggs so that native chicken eggs are safe to consume in raw conditions, "said Prof. Dr. Ir Niken Ulupi, Permanent Professor of the Faculty of Animal Husbandry, IPB University during the Pre-Oration Press Conference at the Baranangsiang Campus, Bogor (21/11).

Because antibodies from the parent are transferred to eggs, the native chicken eggs will always be clear of zoonotic salmonella. While in purebred chickens, despite being given a good feed but antibodies in their blood are few so they are unable to cope with germ attacks from outside.

"There is even a prevalence of purebred chicken eggs affected by salmonella 3.12 percent. If there are 100 eggs, there are eggs that are exposed to salmonella. If it is not boiled, it can cause diarrhea (mild), typhus (moderate) or severe death. If there are people who have typhus, it is rarely suspected that the cause can be from eggs, "he said.

According to him, the results of the study showed that native Indonesian chickens and native chickens had the ability to live at high temperatures in the tropics, with marginal or poor quality feed and an unhygienic environment and lower maintenance costs. The chicken is still alive and continues to experience an increase in population although not high.

Genetically, the HSP-70 gene (which controls the ability to adapt to hot environments), the disease control gene, the TLR4 gene (which controls the body's resistance to bacterial infectious diseases) and the Mx gene (which controls the body's resistance to viral infections) and the SCD gene that controls Fatty meat can have a higher expression in native chickens and local Indonesian chickens than purebred chicken.

"Thus, native chickens and local Indonesian chickens have the advantage of being resistant to a hot environment, resistant to bacterial and viral infections. Kampung chicken meat has higher intramuscular fat with a distinctive but healthier taste. This is because the cholesterol and malonaldehyde content is lower than the meat produced by purebred chicken, "he added.

However, these advantages must be followed by an increase in the growth rate of native chickens and local chickens. In order to act as meat producers, these native chickens can be crossed with parent stock brokers, so that the speed of growth increases.

"This is what Prof. Cece Sumantri, Permanent Professor of the Faculty of Animal Husbandry of IPB University, did. The local chicken IPB D1, the new family of Prof. Cece pioneered and this team can be harvested at the age of 12 weeks with a live weight equal to broiler chickens aged 5 weeks (1.5 kilograms of peer tails). "This D1 IPB chicken has obtained a decree from the Ministry of Agriculture with number 693 / Kpts / PK.230 / M / 9/2019," he explained.

Prof. Niken added that the development of native chickens and local chickens needs to be handled industrially. Industry or universities or research institutions can act as breeders to provide quality seeds. In addition, regulations are needed that guarantee the protection of all parties involved. (NR)
