Abstract

A study was conducted to identify the polymorphism in the intron 3 of the Growth Hormone (GH) gene and also to evaluate the association of the GH gene polymorphism with growth parameters and dressing percentage in the Sumba Ongole (SO) cattle. A total of 267 individual DNA samples were used in the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) analysis. The SO cattle growth parameters data (n=44) including birth weight (BW), weaning weight at 205 days of age (WW205), yearling weight at 365 days of age (YW365) and also dressing percentage (DP) (n=122) were investigated in this study. There were three genotypes (AA, AB, and BB) of the GH gene based on the PCR-RFLP analysis with allele frequency was 0.87 and 0.13 for A allele and B allele respectively. The highest genotype frequency in the SO cattle is AA (0.76) and the lowest is BB (0.02). The Heterozygosity Observed (Ho) value in the SO cattle population is 0.23 and Polymorphism Information Content (PIC) value is 0.20. Therefore, the genetic diversity in the SO cattle based on the GH gene polymorphism is quite low. There is no association (P>0.05) in BW, WW205, YW365, and DP with genotypes of the GH gene. As the result, the GH gene in this study cannot be used as a genetic marker in the SO cattle breeding program.

Abstract

An estimation of most probable producing ability (MPPA) value based on the calves performance is very important for the cow selection. The birth data record of 48 Sumba Ongole (SO) cows and record data from 52 callf birth’s performance were used to estimate the value of MPPA. High of r value (r > 0.30) was obtained at the body length (BL). Birth weight (BW), withers high (WH) and chest girth (CG) had a moderate value (0.10 < r < 0.30) of repeatability. The MPPA value of the cumulative calf birth’s performance of cows based on the highest birth records was 4.64 (cow number 3770) and the lowest was -4.64 (cow number 2283). Calf number B2076 (cow number 3586) had the highest ratio of WH (115.70); BL (124.26); CG (118.90), while the highest ratio of BW (168.35) was obtained in calf number B2095 (cow number 3731). It was concluded that the BW of birth had a moderate value of r (0.10) and could be used as a selection criteria accurately.

Abstract

A feeding trial was conducted to study the use of natural limestone meal originated from Bukit Kamanglocated at Agam district of West Sumatra to substitute fresh water oyster shell as the main source ofcalcium in diet of laying hens. The mineral feed formula, as treatments, composed of limestone in combinationwith freshwater oyster shell in five different percent ratios: 100:0; 75:25; 50:50; 25:75 and 0:100. The mineralswere mixed in the level of 6 % into basal diet composed mainly corn, rice bran and concentrates. The fiveexperimental diets were then fed to 150 laying hens. They were divided into 5 groups; each group wassubdivided into 3 replicates groups containing 10 hens. Parameters measured included: feed intake, eggproduction, FCR, eggshell quality, Ca and P retention, tibia bone mineralization. Results showed the nutritivevalues of limestone of Bukit Kamang as mineral source of laying hen diet were found not significantlydifferent from those of oysters shell. The hens fed with diet supplemented with Bukit Kamang’s limestonetended to give better laying performances than those of supplemented with fresh water oyster shell. Thelaying performances, egg shell quality and Ca and P retentions did not significantly improved, when limestonewas mixed by oyster shell.

Abstract

Samples of limestone composites were measured for hardness in 5 difference colors: black, darkblue, blue, light blue and white. Limestone was then ground and particle sizes of meal were measured.The meal were mixed with other locally available materials to produce 5 difference mineral formulas:P1: 100% limestone meal, P2: 50% limestone meal + 50% fresh water oyster shell meal, P3: 35%limestone meal + 30% fresh water oyster shell meal + 35% bone meal, P4: 35% limestone meal + 30%fresh water oyster shell meal + 34.2% bone meal + 0.5% salt + 0.3% micro minerals and P5: 100% freshwater oyster shell meal. The formulas were stored for 12 weeks. Samples were taken weekly foranalyzing of moisture content and physical properties. By a feeding trial the five mineral formulas weremixed in the level of 6 % into basal diet and fed to 150 laying hens for 24 weeks. Parameters measuredincluded body weight, feed intake, egg production and FCR. Results showed that the composites ofBukit Kamangs’ limestone had difference hardness. The strongest was found by the black composite of23.4 HRc-C or 245.0 BHN. The meal products contained large particles (>0.42 mm) of 17.8%. Moisturecontent of mineral formulas increased during storage, but their physical properties were no significantchanges. The highest moisture increase was found by the product of 100% limestone, but it could bereduced by mixing with oyster shell meal and bone meal. The best laying performances (P<0.05) werefound by the hens fed with diet supplemented with mineral formula containing limestone, fresh wateroyster shell and fortified with micro minerals.

Abstract

The pituitary transcription factor (Pit-1) gene is one of the considered genes that responsible to growth in cattle. A specific Pit-1|HinfI gene polymorphism located within exon 6(g.1256G>A) has been shown to be associated with growth and milk traits in cattle. This study aimed to identify the Pit-1|Hinf1 gene polymorphism in Grati-Ongole Grade cattle (Grati-OG cattle). A total of 107 genomic DNA of Grati-OG cattle were used in this study. The detection of polymorphism was performed by PCR-RFLP method. Only AB and BB genotypes were succesfully identified with the frequency of 0.009 and 0.991, respectively. Whereas, the frequency of A and B alleles were 0.005 and 0.995, respectively. The observed genotype frequencies in this population do not deviated from HWE. The value of Ho, He and PIC were 0.009, 0.009 and 0.009, respectively.In conclusion, the Pit-1|HinfI gene polymorphism in Grati-OG cattle is monomorphic and hence it should not be used in further association studies.

Abstract

A study was conducted to assess the genetic characterization of the Sumba Ongole (SO) cattlebased on DNA microsatellites and also to study the potency of SO cattle based on carcass productivity.Blood samples were collected from 28 individual cattle and 12 microsatellite primers as recommendedby FAO were used to identify the genetic characterization of the SO cattle population. Data of carcassproductivity were collected from 506 individual cattle that slaughtered in Karawaci abattoir, Banten,Indonesia. The heterozygosity values of microsatellite loci ranged from 0.143 to 1.000 (mean 0.536).The highest PIC values was 0.814 (locus TGLA122), while the lowest was 0.280 (locus BM1818).Cattle in range of 351-475 kg slaughter weight was most slaughtered in year 2013 and 2014 with carcasspercentage ranged from 52.89% to 53.43%. The highest carcass percentage (56.34%) was obtained fromcattle in range of 626-650 kg slaughter weight while the lowest (51.42%) was obtained from cattle inrange of 250-275 kg slaughter weight. The results of genetic characterization showed that allmicrosatellite locus were highly polymorphic and highly informative for detecting the level of geneticdiversity in the SO cattle population. The results of carcass productivity showed that the SO cattle hasexcellent potential as beef cattle compare with other local breeds cattle in Indonesia.

Abstract

The g.422C>T nucleotide variations in the 5’ untranslated region (5’UTR) of TG gene (called as TG5) has been reported to be associated with level in intramuscular fat (IMF) content or marbling in beef cattle. The objective of this study was to confirm genetic polymorphism of TG5 gene in Bali cattle populations from three different regions as the main resources of Bali cattle in Indonesia. A total of 200 head of Bali cattle have been performed genotyping on TG5 gene using polymerase chain reaction-restriction fragment lenght polymorphism (PCR-RFLP) method and sequence analysis. Results of the study confirmed that TG5 was monomorphic in Bali cattle wherever their origin regions. Moreover, nine candidate SNPs were detected within 5’UTR of TG gene in Bali cattle compared to Genbank reference sequences, although no SNP variations among Bali cattle sample studied. The new other genetic markers within an entire TG gene suggested to be explored and verified for their polymorphisms in Bali cattle. The nine candidate SNPs were also required further verification and validation in a larger sample to be regarded as new SNPs between Bali cattle and Genbank reference sequences.

Abstract

In the area of Cibinong-Citeureup Bogor has many industries, dusty and there are has been acid rain. About 75.63 % people in this area take well water for drinking. It was studied impact of acid rain for well water degradation in order to know the trend and rate of well water pH change. Preliminary research was done in order to make sure the effect of acid rain to well water using soil column leaching simulation. The main research was done by pH monitoring of acid rain and well water in the specific location. The pH of acid rain was monitored in the first 30 minutes on 12 locations from the year of 1999 to 2009, and the well water pH was measured from the year of 1995 to 2009. The acidity (pH) was measured using pHmeter electronic. The rate of pH change was calculated by first order reaction. The result showed that the well water acidity has uptrend (the pH to be lower). The acid rain has a little impact to the acidity of well water (r = 0.68). The rate of acidity of well water has constant value, k = 0.004 year-1.
