Abstract

Genotipe of BB kappa kasein (ĸ-kasein) gene positively influences high milk protein yield. The aim of this research was to verify the use of the к-casein gene as marker of assisted selecion (MAS) of high protein yield in domestic Holstein-Friesian (HF) cattle. Genotyping blood samples was conducted for lactating cows from BPPT-SP Cikole (82 head) and a number of small holders in KPSBU Lembang (190 head). Genotyping the к-casein gene was also conducted for active and non active AI bulls (HF) from BIB Lembang (25 head) and BBIB Singosari (32 head). Varian genotipes were identified trough DNA migration, whereas frequencies of alleles were calculated by Nei Method (1987). The effects of variant genotypes on protein yield and other milk component yields were studied in lactating cows (56 head in BPPT-SP Cikole and 111 head in KPSBU Lembang) by applying Least Square Means (LSM) method of the General Linear Model (GLM). Genotyping the ĸ-kasein gene resulted in three genotypes, namely AA, AB and BB, with two alleles, namely A and B. It was identified that a very limited number of lactating cows with BB genotype (0-9%). These cows produced higher protein yield around 3.37-3.84% than that of AA cows, while AB cows produced protein yield in between, though these differences were not statistically significant (P>0,05). In contrast, AA cows tended to produced higher milk fat yield than BB cows. Cows BB and AB seemingly produced higher dry matter, while both specific density and pH were not affected by variant genotypes of the к-casein gene.  The results showed that BB genotype of the к-casein gene tended to be quitely consistent in controlling high protein yield, so it would be a good oppurtinity to be used as MAS of milk protein yield in HF domestic.

Abstract

Information about genetic distances among populations (geographics) of local swamp buffalo is less published. Genetic distance analysis was done among seven local swamp buffalo populations trhough a morphological analysis. Female and male buffaloes were observed for a total number of 905 hds, originating from the Provices of NAD (100 hds), North Sumatera (51 hds), Banten (180 hds), Central Java (203 hds), South Kalimantan (121 hds), NTB (200 hds), dan South Sulawesi (50 hds).  Genetic variation among buffalo populations was calculated by discriminant function of Mahalonobis distance. Genetic distance was estimated by MEGA program. Morphometric measurements of female buffalo in North Sumatera were larger (P < 0,01) than those of buffaloes in Banten, South Kalimantan, NAD and South Sulawesi. Morphometric measurements of male buffalo in South Sulawesi were larger than those of buffaloes in Central Java, Banten, and NAD. Chest width was the highest different morphometric factor (0.969). Buffalo from NTB had the highest similarity (95.0%), followed by buffaloes from North Sumatera (74.51%) and South Sulawesi (74.19%); while the lowest one was from South Sulawesi (38.02%) and Banten (49.44%). Morphological distribution map indicated existence of three local swamp buffalo groups. Grup 1 was presented by buffalo from NTB, distributed in the II and III quadrants. Group 2 was presented by buffaloes from five locations (North Sumatera, Central Java, South Kalimantan, South Sulawesi, and Banten), distrributed in I and II quadrants, and a smaller part distributed in III and IV quadrants. Group 3 was presented by buffaloes from NAD and a smaller part from South Kalimantan and Banten, distributed in IV quadrant. The lowest genetic distance was identified between buffaloes in NAD and South Kalimantan (0.348), while the highest one was between buffloes in Banten and South Kalimantan (1.883). Based on phenogram tree structure, the observed local swamp buffaloes could be classified into 3 cluster, namely: Cluster 1 from South Kalimantan, NAD and Banten; Cluster 2 from South Sulawesi, Central Java and North Sumatera, and Cluster 3 from NTB.

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

Follicle stimulating hormone (FSH) is a pituitary expressed glycoprotein hormone that regulatesreproduction in mammals which composed of α and β-sub unit. The β-sub unit dictates its bindingspecificity with their receptor (FSHR). This study aimed to identify polymorphism of FSH β-sub unitand FSHR genes, and its effect to superovulatory response traits on superovulated cows. Study was doneon 32 cows including Angus, Friesian Holstein (FH), Limousin, Simmental and Brahman in CipelangLivestock Embryo Center. Cows used have been treated superovulation and mated by artificialinsemination. Superovulation response (SR), ovulation rate (OR), fertilization percentage (FP) andviable transfer embryo percentage (VP) were analyzed to investigate the effect of FSH β-sub unit andFSHR polymorphism. Allele frequency of FSH β-sub unit|PstI and FSH|AluI were opposite withinspecies. Mostly B allele and C allele for FSH β-sub unit and FSHR respectively have a high number inBos taurus species while those were in contrast in Bos indicus species. The highest heterozygosity wasfound in FH cattle (0.250) for FSH β-sub unit and Brahman (0.333) for FSHR. Significant effect was found between FSHR gene polymorphism with ovulation rate where CC genotype was higher (P<0.05)than CG and GG genotypes.

Abstract

Growth hormone (GH) is an anabolic hormone which sintesized and secreted by somatrotop cell inpituitary anterior lobe. GH exert its effect on growth and metabolism by interacting with a specificreceptor on the surface of the target cells. Growth hormone receptor (GHR) has been suggested ascandidate gene for traits related to meat production in Bovidae. The objectives of this study were toidentify polymorphism of GH and GHR genes in buffalo. The 452 DNA samples buffalo were collectedfrom five populations in Indonesia (Siborong-Borong-Medan (65), Lebak-Banten (29), Pandeglang-Banten (180), Semarang-Central Java, and Mataram-West Nusa Tenggara (103)). A gene fragment of theGH|AluI gene at 432 bp located on exon 3 and GHR|AluI gene at 298 bp on exon 10 were successfullyamplified by using the techniques of a PCR (polymerase chain reaction) and genotyped by PCR-RFLP(restriction fragment length polymorphism) then -SSCP (single strand conformation polymorphism). Theresults showed no polymorphisms were detected in these genes. All buffaloes tested had LL genotype forlocus GH|AluI and AA genotype for locus GHR|AluI.

Abstract

Myostatin (MSTN) is a protein inhibit muscle growth. This protein is a member of a superfamily ofmolecules called transforming growth factors beta (TGF-b). Deletion in c.960delG (1-bp deletion atposition 960) disrupts the reading frame from amino acid (aa) position 320 to ending in a premature stopcodon in aa position 359 have been found in Norwegian White Sheep. This deletion in the myostatingene is responsible to increase muscle mass, also known as 'double muscling', in sheep. The purpose ofthis study was to identify the polymorphism of myostatin gene in c.960delG locus of local sheep inIndonesia. The 832 DNA sampels from sheep were collected from 13 populations belonging to thePriangan (86), Javanese Thin Tail (389 i.e. Jonggol, Banjar, Ciomas), Javanese Fat Tail (94), West NusaTenggara (136), Rote Island/East Nusa Tenggara (35), Kisar Island/Southwest Maluku (22),Donggala/South East Celebes (45) and Batur cross breed/Wonosobo, Central Java (25). A gene fragmentof MSTN c.960delG length 299 bp was successfully amplified by using the technique of PCR(polymerase chain reaction) and genotyped by SSCP (single strand conformation polymorphism). Theresult showed no polymorphism in this gene. All sheep tested had G/G genotype for c.960delG locus.
