Abstract

The aim of this study was to evaluate genetic analysis including heritability and further phenotypicand genetic trends of reproductive traits in Bali cattle. Reproductive traits studied were age at firstcalving (AFC), calving interval (CI) and pregnancy rate (PR). Data of reproductive traits were collectedfrom Breeding Centre of Bali Cattle, Denpasar-Bali at the year period of 2000-2007. To evaluate thegenetic analysis, heritability were estimated using the Mixed Model Least Squares and MaximumLikelihood procedure. The phenotypic and genetic trends were calculated using regression equation.Estimation of heritability for AFC, CI and PR were 0.22, 0.41 and 0.40, respectively. The phenotypictrend of AFC, CI and PR decreased at an average rate of 1.70 month, 10.4 days and 0.75% per year,respectively. The same pattern was showed for genetic trends for AFC, CI and PR decreased at 0.38month, 4.25 days and 0.30% per year respectively in the same period. The heritability of reproductiontraits in Bali cattle were considered as moderate to high (0.22-0.41) which means that the selectionprogram will be more effective and efficient in improving the genetic merits in Bali cattle.

Abstract

This study was aimed to determine the profiles of pig farming systems. Participatory situationanalysis was employed to gain data relating to pig profiles in the urban and rural areas of Manokwari.Due to the interests of combining many correlated data, multivariate analysis using Principal ComponentAnalysis (PCA) was performed. Cluster Analysis using Agglomerative Hierarchical Clustering wasapplied for analysis of merge samples based on similarity in components’ composition across sites.There were various twelve classes of pig profiles in Manokwari. In principal component of the first axiscorrelation of several components shows strong positive relation e.g. in piglets, sows, and total herd size.Status of region in the first axis of PCA (P1) through which pigs were raised had negative correlation,including grower, household member and pig production. In the second axis (P2), negative correlationswere shown in piglets, grower, boars, total herd size and the Pig Production Potential (PPP). Status ofregion has underpinned profiles of pigs. Several farmers were able to manage their farm continuity in asteady composition. Selling pigs was the main aim and few farmers play a role as pure breeder.

Abstract

The aim of the study was to produce polyclonal antibody (rabbit anti-ovPAG) which could detectPAG in the urine of pregnant ewes. Twelve rabbits were immunized against ovPG DEAE-TrisHCl (DT),DEAE-NaCl 20mM (DN2), DEAE-NaCl 40mM (DN4), DEAE-NaCl 80mM (DN8), DEAE-NaCl160mM (DN16), DEAE-NaCl 320mM (DN32) and DEAE-NaCl 1M (DN1) and NaCl 0.9 % as aplacebo. The 0.5 ml of isolate (purified from ovine cotyledon) was emulsified in equal volume withcomplete and incomplete Freud’s adjuvant. The mixture of each isolate and adjuvant was injected atmutiple sites along the dorsal area of rabbits by subcutaneous route. Blood were collected from marginalear vein, starting before first injection (baseline) and every 14 days. Rabbit anti-ovPAG were measuredusing Modified ELISA Technique. By using Western Blot Technique, DN32 showed the best immuneresponse among others and also could differenciate ovPAG in the urine of pregnant ewes It could beconcluded that ovPAG DN32 is a specific source of rabbit anti-ovPAG production. Protein of ovPAG atmolecular weight 31 kDa is a pregnancy protein marker of garut sheep and could be developed as amajor protein for producing antibodi.

Abstract

The main objective of this research is to present an alternative approach to meet beef selfsufficiencyin West Papua, Indonesia. It mainly focuses on calculating the needed number of productivecows to enhance beef production in the province. Out of the total farmer households in Manokwari,Indonesia, 189 farmer-respondents were selected as samples of the study. Selection of the sample wasbased on the number of cattle kept in every age group (less than one (<1) year old; one to two (1-2)years old, and more than two (>2) years old and the number of productive cows. Secondary data camefrom the time series data of the number of slaughtered cattle vis-à-vis the population of all districts inWest Papua Province from 1980-2008. Data were analyzed using the Partial Adjustment Model (PAM)and Ordinary Least Square (OLS) method. Results of the study showed that beef self-sufficiency in WestPapua depend on the availability of the number of productive cows to produce ready-slaughtered-bull inthe previous year. Particularly for West Papua, to produce one unit of bull in the tth –year, with theassumption that cattle mortality is 4.92%, a number of 2.38 animal units AU of productive cows must beprovided in the previous two (2) years.

Abstract

The study was carried out to investigate the effect of marination, performed by soaking of beef ingarlic juice, on microbiological and physical properties. The study was committed to a completelyrandomized design, with 5 treatments, i.e.: T0 (unmarinated beef, as a control), T1, T2, T3, and T4 thatbeef were marinated in garlic juice for 5, 10, 15, and 20 minutes, respectively, at room temperature(25⁰C). Each treatment consisted of 4 replications. Examination upon experimental parameters wasconducted after marinated (and control) beef was stored for 8 hours at room temperature. Total bacteria,total coliform and water holding capacity of beef were significantly (P<0.05) affected by marinationwith garlic juice. Conversely, cooking loss was not significantly affected (P>0.05) by the treatments. Asa conclusion, marination of beef with garlic juice could reduce total bacteria, total coliform, and waterholding capacity, but could not reduce cooking loss.

Abstract

Free radical levels can be higher than the level of endogenous antioxidants in the body so thatuncomfortable conditions in the body of dairy goats could happen. To anticipate this uncomfortableconditions will be given feed supplement (FS) as source of antioxidants (AOX). FS contain mixturepineapple rind meal and antioxidant minerals (AOXM) each 25 ppm Zn and 10 ppm Cu. Thisexperiment was carried out to investigate the effect of feed supplements as antioxidant source on milkquality of dairy goats. Sixteen Etawah dairy goats in the second lactation were used in the experimentthat conducted using randomized block design with 4 treatments and 4 replicates. The treatments wereR0 (grass + concentrate), R1 (R0 + FS containing 0.04 % AOX), R2 (R0 + FS containing 0.06% AOX),R3 (R0 + FS containing 0.08 % AOX). The data collected were analyzed using Anova. The result ofphytochemicals analysis indicated that feed supplement contained flavonoid, polyphenols, sesqiuterpen,mopnoterpen, steroids, quinones and saponins. The results of study showed that there were difference(p<0.05) among treatments on blood and milk cholesterol and milk lactose, but there were no difference(P>0.05) on milk yield, milk fat, milk protein and milk antioxidant. The conclusion of this study was thefeed supplements containing 0.08 AOX produced the best response to milk quality of dairy goats.

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

Each four young bulls of Madura cattle and Ongole Crossbred (OC) cattle were used to study theefficiency of ruminal fermentation by comparing the proportion of Volatile Fatty Acid (VFA) of thesetwo breeds which were raised under intensive feeding. All the cattle were in about 1.5 years-old with anaverage body weight of 147.75 ± 14.57 kg and 167 ± 22.57 kg, for Madura and OC cattle, respectively.They were fed Napier grass (Pennisetum purpureum) hay, and concentrate feeding consists of pollard,soybean meal and rice bran for 10 weeks. Parameters measured were concentration of VFA at 0, 3 and 6h post-feeding and pH. The concentration of VFA in both Madura and OC cattle was peaked at 3 h postfeeding,being 136.1 mmol and 158.9 mmol, respectively, and then were decreased at 6 h post-feeding ata level of 58.1 and 98.2 mmol, respectively. The proportion of acetic acid in Madura and OC cattle were53.33% and 52.0% of total VFA, respectively, while the proportion of propionic acid and butyric acidwere 28.80% and 17.87% for Madura cattle, and 30.71% and 17.28% for OC cattle, respectively. Inaddition, the Acetic/Propionic ratios were 1.85 and 1.69 for Madura and OC cattle, respectively. RumenpH conditions of both cattle breeds tended to be basic, i.e. Madura cattle was ranged at 8.0-8.4, while thePO cattle was ranged at 7.6-8.4. In conclusion, both cattle breeds (Madura and OC cattle) have a similarefficiency to utilize the feeds in the rumen.

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.
