Hubungan Keragaman Gen Insuline-like Growth Factor 2 (IGF2) terhadap Sifat Pertumbuhan pada Ayam Kampung
Abstract: Kampung chicken is
one of Indonesia native chickens which has slow growth and it needs to be
improved. Growth is a quantitative trait which is controled by many genes. One
of the genes which plays a crucial role in controling growth is IGF2 gene. The
objective of this study was to analyze the association of IGF2 gene
polymorphisms with growth traits in kampung chicken. A total of 56 male and
female chicks were maintained for 16 weeks and genotyped using PCR-RFLP
method.Result showed there was TC muation on IGF2
gene and it was polymorphic in kampung chicken. Frequency of heterozigous TCwas
the highest than the others. There was no association between IGF2 gene
polymorphismswith growth traits in kampung chicken. It can be caused by the
synonimus mutation on IGF2 sequence that does not alter the amino acid. Bot of
the nucleotides coded for histidine. It may not give different effect toward
the growth traits in kampung chicken.
