Abstract

The objectives of this study were to identify the productivity and genetic diversity of local cattle inCiamis West Java based on DNA microsatellite, in order to provide the basic information for its rearing,conservation and development. Eighteen of local cattle were kept for 58 days by feeding concentratesand rice straw. The measured parameters were weekly body weight as well as carcass percentage. Thepercentage of comparing carcass was taken from PO, Bali and crossbred cattle from local cattle withLimousin, Simmental, Brahman and Angus cattle. Data were analyzed using Excel software and SAS(2004). Blood samples were taken from two subpopulations i.e., 46 and 52 samples from Tambaksariand Cijulang areas, respectively. Other DNA samples were collected from Bali, PO, Limousin, Simental,Brahman and Angus cattle. Genetic diversity and phylogenetic analysis were analyzed using 3microsatellite loci, that were INRA35, HEL9 and BM2113. The genotyping data were analyzed usingPOPGENE.32 program, while phylogenetic trees were analyzed by MEGA 4. Average daily gain (ADG)of local cattle in Ciamis was 0.62±0.23 kg/head/day with a carcass percentage was 51.62±1.80%. Thecarcasses percentage of local cattle in Ciamis was not significantly different from those of Bali, PO, andcrossbred cattle. The genetic diversity of local cattle in Ciamis was categorized in the medium level, thediversity of local cattle in Tambaksari subpopulation was higher than in Cijulang subpopulation. Localcattle in Ciamis had a closer genetic distance with the PO cattle.

Abstract

The body weight records of 1221 heifers were used in this study collected from PT Taurus DairyFarm Sukabumi from year 2001 until 2011. The records that could be used for analysis were 373 out of1221 heifers, having completed data from birth to first mating period. Three different models i.e,Logistic, Gompertz, and von Bertalanffy were performed to analyze the growth rate of heifers. Theresults showed that the three models had different accuracy and heavily depend on age, environment andduration of recording. The body weights of sexual maturity and on certain ages were affected by theduration of recording. The Gompertz model was performed as the simpliest model in form ofcalculation. On the other hand, the Logistic was more difficult to calculate. All models indicated highaccuracy with the determination coefficient (R2) more than 90%. Based on the comparison, theGompertz and Logistic model are recommended for predicting the growth rate of heifers from birth tosexual maturity.

Abstract

The aims of this study were to obtain information on the mechanism of molting and the prolactinhormone levels affecting egg production. The study utilized AP (crossbred of Alabio ♂ with Peking ♀)and PA (crossbred of Peking ♂ and Alabio ♀ ducks) with a total of 180 birds. The observed variableswere the duration of cessation of egg production before and after molting, the prolactin hormone level inthe period of molting, the egg production period before and after molting. The data was analyzed usingANOVA, regression and correlation. The results showed that AP crossbred had fewer molting (23.33%)compared to PA (50.00%). The mechanism of molting is always preceded by cessation of eggproduction, molting and relaying. The prolactin hormone concentrations of AP and PA in the periodbefore and after molting were significantly higher than in the period of molting. At the egg productionperiod before molting, the prolactin hormone concentration of AP ducks was higher than the PA ducks.So that the egg production of AP before molting (0-16 weeks) was higher than the PA. The eggproduction of AP was higher than PA, 256.66±6.00 vs 232.22±6.64 eggs for 48 weeks. So it can beconcluded that the prolactin hormone affects the molting and egg production.

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.

Abstract

The research was conducted to identify Alu-I locus of growth hormone (GH) gene in Bali cattle byusing 232 blood samples collected from Bali and Lombok islands. PCR-RFLP and sequencing methodswere used to detect the polymorphism and nucleotide sequence at Alu-I locus of GH gene. The resultshowed that Bali cattle from Bali island has one genotype (LL genotype), whereas Bali cattle originatingfrom Lombok island has two genotypes, namely LL and VV genotypes, respectively. The L and V allelefrequencies from Bali and Lombok islands were 1.00 and 0.00; 0.99 and 0.01, respectively. Thesequencing result of Bali cattle LL genotype showed an AGCT sequence of enzyme Alu-I restriction site.Based on polymorphic informative content (PIC) value, it can be concluded that Alu-I locus of Balicattle from Bali and Lombok islands were monomorphic and polymorphic, respectively.

Abstract

This research was carried out to make a difference and to predict genetic distance some sheep thatare genetically related to each other based on the body size measurements. Nineteen bodies size of 323sheeps of five sheep breeds; namely Barbados Black Belly Cross (BC), Garut Local (GL), GarutComposite (GC), Sumatra Composite (SC) and St. Croix Cross (SCC) were measured. Analysis ofvariance and canonical discriminant analysis, Mahalanobis distance, plotting canonical and dendogramwere performed using PROC GLM, PROC CANDISC, PROC CLUSTER and PROC TREE of SASsoftware ver. 9.0. Index Length, Width Slope, Depth Slope, Balance and Cumulative Index of GC sheepwere significantly higher than the four other breeds. Canonical discriminant analysis successfully coulddifferentiate among the five sheep breeds. All five breed were divided into two groups: the first groupconsisted of SCC, SC and BC; and the second group consisted of the GL and GC. The results of geneticdistance estimation showed that the SCC had a value of sheep genetic distance closest to SC (10.83) andBC (27.98), while GL had the closest distance to GC (66.60). The tail width, horn base circumference,horn length (canonical 1) and variable length of the tail and body length (canonical 2) were the breeddifferentiation variable in this study.

Abstract

The study was carried to identify the phenotypic variation of Alabio duck (Anas platyrhynchosBorneo) being kept by smallholder. This research was conducted in Hulu Sungai Selatan (HSS), HuluSungai Tengah (HST) and Hulu Sungai Utara (HSU), South Kalimantan from May until November2009. Six hundreds (75 males and 525 females) duck characterized in this study was age ranged from5-5.5 months old. The observed parameters were plumage color, color feature, plumage shine, the colorof bill, feet and shank. The results showed that the ducks from three locations (HSS, HST and HSU)performed different plumage color and color feature. The dominant plumage color of the Alabio maleduck was grayish white on the neck (44-56%), grayish black on the back (40-60%) brownish grey onthe chest (52-80%), while the wing was more dominated by blue-green (56%) and black (80%) in thetail. Whereas the female ducks was dominated (70-100%) brown spotted color, the rest blackish gray attail, such as back, neck and chest. Twinkle Alabio duck plumage on males and females have the highestpercentage was the glint of silver (100%) and of shiny blue-green for males (85-100%). The percentageof phenotypic color of bill, feet and shank of male and female ducks were lite yellow (40-60%), brightorange (12-44%), pale yellow (8-28%) and black (4-12%).
