Abstract

The decrease in fertility is considered to be the main cause of reproductive loss in dairy cattle and beef industry. Many candidate genes that play an important role in fertility and embryonic development. The purpose of this study was to detect genetic variations of the growth hormone gene family (GH|MspI, GH|AluI, GHR| AluI, GHRH|HaeIII and Pit-1|HinfI) and its association with superovulation response, ovulation, fertilization and transferable embryos rate. A total of 45 blood samples taken from cows that have been superovulated Angus, Brahman, HF, Limousin and Simmental. DNA was extracted with phenol-chloroform protocol followed by polymerase chain reaction technique (PCR) using specific primers for GH, GHR, GHRH and Pit-1 gene. PCR product was cut with restriction enzyme MspI, AluI, HaeIII and HinfI and electrophoresed on agarose gel and stained with ethidium bromide (EtBr). Superovulation is done by injecting a totally of 20 ml FSH for 4 days. Injecting the prostaglandin hormone (PGF2α) was performed on the eleventh day of CIDR implantation. Artificial insemination (AI) performed two or three days after the injection of PGF2α and Flushing was done on the seventh day after the AI.  The results showed that the Angus, Limousin, Brahman and Simental GH loci diversity of GH|MspI, GH|AluI, GHR|AluI, GHRH|HaeIII and Pit-1|HinfI was not associated with superovulation response, ovulation, fertilization and transferable embryo rate. In HF dairy cattle, genotype on Pit-1|HinfI AA has higher percentage of superovulation response (P < 0.05) when compared to AB genotype, but did not differ to BB genotype. Dairy cattle HF AA genotype also had higher ovulation rate (P < 0.05) when compared to AB and BB genotypes, but AB and BB have the same ovulation rate. Key Words: Polymorphisms, Growth Hormone Genes and Reproduction traits.

Abstract

The aim of study was to identify the association of FSH beta-subunit gene polymorphisms withsperm quality traits. A total of 470 samples of normal mature bull from several breeds were used forpopulation study and 127 bulls from National and Regional AI centre of Indonesia for association study.To amplify, a PCR-RFLP method was used and digested with Pst1 restriction enzyme. The allelefrequency of the A and B in Bali cattle were (0.000) and (1.000), respectively. The absence of otherallele A suggested that the Bali cattle was monomorphic, while Brahman, FH, Simmental and Limousinewere polymorphic. The highest observed heterozygosity were found in Limousine (0.318) and thehighest expected heterozygosity were in Simmental (0.420). The higher incident of percentage of spermabnormalities were found in Simmental, Limousin, Brahman compared to Bali and FH. Among all typesof sperm abnormalities, the abaxial and microcephalus were found in highest number.
