Abstract

The aims of study were to analyze (i) income of beef cattle farming, (ii) ability of farmers to meettheir obligation for returning credit, (iii) role of character, capacity, capital, collateral and conditions(5C) and its effect on credit return. The study was conducted using survey methods on farmers (fatteningand cow-calf operation), who use credit. Sample location was determined using two stage clusterrandom sampling based on beef cattle population, namely region of Grobogan, Blora, Rembang,Wonogiri and Boyolali. Number of respondents was 50 for fattening and 50 for cow-calf operation. Datawere analyzed by descriptive and inferential statistic, which consisted of scoring, income and multiplelinear regression. Results showed that income per-year of beef cattle fattening was greater than cow-calfoperation (IDR 8,954,208.00>1,606,786.00), as well as its contribution to the household farmers’income (49.45>14.91%). Credit return ability was 61.35% based on amount of credit IDR 22,482,510.Five-C analysis resulted that character and capacity of farmers were in adequate category, while capital,collateral and condition were IDR 14,932,500.00, IDR 58,740,000.00 and IDR 14,440,600.00. Capitaland collateral had significant effects, while character, capacity and condition had no significant effectson credit return.

Abstract

This research was aimed to study the influence of animal age and concentration of the acetic acidsolution on physical and chemical properties of pigskin gelatin. The experiment used CompletelyRandomized Design (CRD) with two factors. The first factor was animal age consisted of 3 levels (5, 7and 9 months). The second factor was concentration of acetic acid solution consisted of 3 levels (2, 4and 6 percents). The result showed that animal age had significant effect (P<0.01) on the yields, gelstrength, viscosity, protein content and pH value but interaction of animal age and concentration ofacetic acid had no significant effect (P>0.05) on the yields, gel strength, viscosity, protein content andpH value. It was concluded that pigskin gelatin from ages of 5, 7 and 9 months and acetic acidconcentration of 2, 4 and 6% had similar characteristics to the commercial gelatin, but the optimumproduction of gelatin was combination of pigskin gelatin from 7 months and of 2% acetic acid.

Abstract

This survey aims were to determine the potency of dairy cattle development, and to find therelationship among of various factors to improve productivity and income of dairy cattle farmers.Semarang, Boyolali and Banyumas districts were taken as study location. Total respondents were 495farmers, in which 225 farmers were members of the Village Unit Cooperative (VUC), 180 farmers weremember of Various Business Cooperative (VBC) and 90 farmers were member of Farmer GroupAssociation (FGA). Primary data were obtained through interviews with farmers and secondary datawere obtained from related institution. Descriptive and Structural Equation Modelling (SEM) analysiswere used in the study. Based on LQ (Location Quotiens) analysis, dairy cattle in Central Java waspotential to be developed. The LQ value of Semarang, Boyolali and Banyumas districs were 4.57, 7.68and 0.46, respectively, with 4.24 on average. The dairy cattle farmer income was IDR 1.024.095/monthwith an average of scale ownership lactation cattle was 2.7 head/farmer. Model Goodness of Fit of SEMwas fit with the SEM requirement. The productivity was influenced significantly (P<0.01) byenvironmental, economic, institutional, and social factors. Dairy cattle farmer income were influencedhighly significant (P<0.01) by technical and institutional factors (P<0.05) of the income. These resultsindicated that the role of technical factors, social, economic, institutional and business environmentneeds to be considered in order to increase business productivity and farmer incomes.

Abstract

This study aimed to determine the effect of medium chain fatty acids (MCFA) on propionic acidsand lamb meat chemical quality. The treatment given was R1: feed without medium chain fatty acids(MCFA), while R2 dan R3 were the feed contained 1.0% and 1.5% of MCFA, respectively. The twelveheads of lambs yearling weight of 16-17 kg were used as materials. Biological trial was done for threemonths and then was slaughtered. Before being slaughtered, the animal was taken rumen fluid to beanalyzed for propionic acid. The carcass was sampled to be analyzed for chemical composition,cholesterol and fatty acids content. This study showed that methanogenic inhibitor feed with 1.0-1.5%MCFA could be used as sheep feed, and the results: the propionic acid content in rumen increased 29.59– 36.11%. The cholesterol content decreased 7.14-10.06%. For the meat fatty acids composition,unsaturated fatty acids increased 9.05 – 17.96%. while saturated fatty acid decreased 6.59 – 11.88%.

Abstract

The aim of this research was to determine the profit obtained from breeding of Timor deercommercially. This research was done in East Java. Survey method was used to answer the objective.The study location were selected by purposive sampling. Usually deer was develop in conservation area,but because the area was decrease so the number of deer also decrease. Model of deer raisingdevelopment should be improved not only for conservation but also for commercial purpose. Theoptimum deer raising were considered and monitored with a purpose to maximize commercial Timordeer by using Multiple Objective Goal Programming (MOGP) to find the Optimistic Rate Estimation.The result of this study showed to get the optimum benefit, it had to be applied together withconservation and commercial effort at the same time. Results of study showed that profit was taken fromselling velvet was 164.46%. Profits taken from selling antler was 350.56%, from selling alive deer was394.28%, from selling recreation tickets was 259.08%, from selling venison1 was 135.98%, and fromselling deer leather was 141.24%. Operational cost spent were 168.46% for feeding cost, 213.23% formaintenance cost, and 232.04% for labors’ salaries. The amount of operational cost required in MOGPmodel, with lower expenses and commercial priority were 185.54% for feeding cost, 253.13% formaintenance cost, and 246.95% for paying labors’ salaries. The MOGP model result with commercialpriority reached 335.21%, while in MOGP model with lower costs and commercial priority gave profitfor breeders up to 381.26%.

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

An evaluation was conducted of the returns to fattening cattle of small- and medium-scaleenterprises in East Java. The objective was to analyze income over feed costs (IOFC) based on locallyavailable feedstuffs to increase liveweight gain. The study was conducted during July-September 2010and January-March 2011, representing relative dry and wet season. The breeds were PO and Limousinand Simmental crossed with PO (LimPO and SimPO). Small-scale farmers owning 1-2 bulls andmedium-scale farmers fattening 10-20 bulls in one period. Fattening period was 58 and 46 days,respectively for dry and wet season. Monthly measurements included liveweight, feed intake, input andoutput prices. Mean values of growth rates and IOFC were compared using t-tests. The results indicatedthat, for small-scale operations, SimPO bulls gave a significantly higher return than either PO or LimPObulls. Likewise, LimPO gave a higher IOFC than SimPO in medium-scale operations. Small-scalefarmers achieved equal or higher IOFC for European-cross than medium-scale farmers in both seasons.This reflects that cash outlays for feed were about two-thirds that of medium-scale operations whiledaily growth rates were similar. Small-scale fattening operations using European-cross can befinancially competitive with medium-scale operations in both wet and dry seasons.

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

This research was conducted to study the influence of protected kapok seed oil (PKSO)supplementation in its combination with concentrate, in this case was rice bran (RB) on lipid content ofthin tailed sheep received field grass as basal feed. A number of 24 heads of male thin-tailed sheep wereused as experimental material. These sheep were divided into 8 treatment groups. There were twotreatment factors, i.e. : PKSO supplementation (S) as factor I and RB supplementation (K) as factor II.Factor I consisted of 2 levels, i.e. 0% (S0) and 10% (S1), whereas factor II consist of 4 levels, i.e. 0%(K0), 15% (K1), 30% (K2) and 45% (K3), respectively, based on dry matter (DM) intake. Severalvariables were measured, namely content of intra muscular fat (IMF), iodine number of muscular fattyacid, content of meat cholesterol and omega 6 fatty acid (in this case linoleic acid). The collected datawere statistically analyzed by analysis of variance with factorial treatment pattern (2 x 4) in completelyrandomized design (CRD). Content of IMF in sheep supplemented with 0 and 15% KSO levels was notsignificantly different from those without kapok seed oil (KSO) supplementation at the same level ofRB feeding (3.45 and 3.99% vs 3.01 and 3.75%). Supplementation of protected KSO in combinationwith 30 and 45% RP resulted in significantly increased (P < 0.05) IMF content (4.75 and 5.93% vs 4.32and 5.40%) and significantly decreased (P < 0.05) meat chollesterol content (62.46 and 65.26 mg/100 g vs 89.21 and 72.63 mg/100 g ) also significantly increased (P < 0.05) linoleic acid proportion (15.52 and18.25% vs 3.68 and 4.04%) and iodine number (12.52 and 10.25 vs 4.09 and 4.98).
