Abstract
This study was conducted in order to identify polymorphism of growth hormone
gene in the exon five and to determine the association of GH/AluI polymorphism
with carcass quality in Aceh cattle. A total of 42 DNA genome samples were
extracted from two Aceh cattle population, i.e., Banda Aceh (12), Aceh Besar (30),
and the PCR-RFLP was used to amplify 404 bp of GH gene. The result showed that
the LL genotype was the only genotype found in Aceh cattle population, and the
alele frequency of alel L is 1. This finding indicated that there was not evidence of
polymorphism of GH/AluI in Aceh cattle, and there was not correlation of GH/AluI

gene with carcass quality of Aceh cattle. It could be affected by small number of
sampling size. However, this study suggests that GH gene could be possible used as
genetic marker.

Introducton
The enhancement of beef cattle’s productvty n Indonesa wll be more
approprate f t s done through a selecton whch s not only based on the phenotype,
but also combned wth drect selecton on the level of DNA whch codes the
phenotype n whch the qualty needs to be mproved. The bovne genome map
made based on markers on genome DNA uses molecular technque such as RFLP,
mcrosatellte, mnsatellte, PCR-RFLP, and PCR-SSCP make t possble to dentfy
gene locus whch are responsble for trat varatons havng economc values.
GH gene as a genetc marker s frequently used n researches because growth
hormone gene (GH) s one of the genes whch nfluence growth (D Staso et al.

2005). Casas et al. (2004) reported that QTL for growth trats, carcass composton
and beef qualty was spread on chromosome 1, 2, 3, 16, 17, 19, 20, 21 and 26. GH
gene has a great role n beef cattle’s performance (Breer. 1999), hence t s very
nterestng to dentfy GH gene polymorphsm on Aceh cattle.

Materals and Methods
Ths research ncluded feld and laboratory actvtes. Feld actvty was conducted n Banda Aceh and Aceh Besar slaughterhouses. The DNA extracton and
characterzaton of GH/Alu I gene dversty was conducted n Anmal Molecular
Genetcs Laboratory, Faculty of Anmal Scence, Bogor Agrculture Unversty,
whereas the examnaton of carcass and meat qualty was carred out n Rumnansa
Besar Laboratory, Department of Anmal Producton and Technology. Ths actvty
was done n October 2009 - November 2010.
Blood Sample of Aceh Cattle
Ths research used Aceh cattle’s meat (muscle) n whch ths cattle s local ones
orgnatng from Aceh provnce. Twelve (12) samples were taken n RPH Banda
Aceh, and thrty (30) samples from RPH Antassalam, Aceh Besar (Table 1). The
sample used was longisimus dorsi muscle on the 12th – 13th rb. The cattle slaughtered
were bred tradtonally, n whch durng daytme, they were herded, and put n stalls
at nghts. The slaughter was done tradtonally.

Genome DNA Extraction (Meat)
DNA extracton was done from the meat. The extracton procedure followed
phenol-chloroform method (Sambrook et al. 1989).
GH Gene Amplification
The amplfcaton of GH gene fragment was done usng PCR (polymerase chain
reaction) method. The PCR machne used was thermal cycler (Ependorf 5332). The
arrangement of prmers used can be seen n Table 2.

Analysis Results on Aceh Cattle’ Carcass and Meat Quality
The value of parameter average of Aceh cattle carcass and meat qualty can be 
seen on Table 3. The pH value of the meat n ths research has the average of 5.46,
whch shows the pH range of normal meat 5.4 – 5.8. The meat color s n category I
(score 1 – 5) accordng to SNI (Indonesan Natonal Standard, 2008). The degree of
tenderness 4 -5 s consdered moderate, not too tender and not too tough.

The research results dentfy that Aceh cattle’s carcass/meat has fner meat
fber and ts color s red. The qualty and meat structure greatly depend on types of
meat and locaton. Marblng s also very nfluenced by the breedng system and food
gven.

Conclusons
Based on ths research results, t can be dentfed that the use of GH/AluI only
resulted n LL genotype and monomorphc, so that t cannot be used as a marker to

assocate wth the carcass qualty on Aceh cattle. Ths phenomenon s lkely due to
the lmted number of samples and the exstence of natural selecton towards LV
and VV genotype as the consequence of Aceh cattle adaptaton’s to the local envronment. Thus, a further research s stll necessary, by usng more samples and f
dversty s found, sequencng needs to be done so that t results n more accurate
