Abstract

This study was undertaken to evaluate the performance of vertical integration and independentpoultry producers in East Lombok, West Nusa Tenggara, during the period July to September 2011.Data was collected from a primary field survey of integrated contract and independent producers. Thesample producers were interviewed to collect the required data using a questioner. Supporting data wereobtained from the relevant institution, and poultry association. Thirty integrated contract and fourteenindependent growers were involved to measure farm’s performance with references on numericalperformance (NP) and farmer’ returns. This study indicates that the NP of integrated contract andindependent farms were 315.7 and 317.1, respectively, both was higher than the standard that is 200.Returns for integrated contract farmers were lower than the independent when calculated based on theproduction cycle when this study was undertaken. Integrated contract farmers were attractive to varioustypes of professions, the graduated people of university or college (43.3%) was the most, whilstindependent farmers were dominated by senior high school (50%) with higher experience which wasmore than 20 years.

Abstract

A study to evaluate the productivity of Boer and Kacang goats dam was carried out for 2 years atResearch Institute for Goat Production, Sungei Putih-North Sumatera. The materials used were goatsowned by the institute. The parameters observed were total birth and weaning weights of kid, litter size,parity of dam, pre-weaning mortality and kidding interval. The rate of reproduction and productivity ofthe dam were estimated using Amir and Knipscheer methods and were statistically analyzed usingGeneral Linear Model. The results showed that the total birth and weaning weight of Boer goats werehigher (P<0.05) than that of Kacang goats, while litter size of Boer goats were higher (P<0.05) than thatof Kacang goats. The pre-weaning mortality of Boer goat 15.1 ± 6.02% was lower than that ofKacang. The kidding interval of Boer goats was higher (P<0.05) than that of Kacang. Parity of dam hadsignificant effect on all production traits (P<0.05) except for pre-weaning mortality. Dam reproductionrate of Boer (1.81) was higher than that of Kacang (1.78), while productivity of Boer goat (37.12kg/head/year) was higher than that of Kacang (18.12). It can be concluded that the reproductivity ofBoer and Kacang goats were similar, however the productivity of Boer goat had better than Kacang.

Abstract

An experiment was conducted to study the effect of different meat shops on meat physicalcharacteristics and bacteria population. Sixteen PO carcasses were used in the experiment which wasarranged in a completely randomized design with 4 treatments of different meat shops (traditionalmarket, meat shop, supermarket and slaughter house). Parameters measured were meat pH, waterholding capacity, cooking loss and bacterial total count. The result showed that the average of pH was5.25- 6.03; water holding capacity was 17.07-38.87%; cooking loss was 33.15-48.20 and bacterial totalcount was 1.48x106-10.75x106 CFU/g. It was concluded that bacterial total count in slaughter house andspecial market (meat shop and supermarket) were less than those in traditional market.

Abstract

Eight bulls of Ongole Crossbred (OC) cattle with initial body weight (BW) of 297 + 26 kg (CV =8.75%) fed rice straw treated with urine (RU) (ad libitum) were divided into two groups (each fourheads) to determine the effect of concentrate feeding level on efficiency of eating behavior. The cattlewas given concentrate feeding composed of beer cake and rice bran to make 14% crude protein at 1%and at 2% BW for RUC1 and RUC2 group, respectively. Eating behavior was measured for 3x24 hoursand was performed twice at weeks 2 and 6 of the study. Data obtained were analyzed by t-test. Theresults showed that the level of concentrate feeding affected the intake of urinated rice straw (P<0.01)and daily BWGain (P<0.05), but the effect was not found (P>0.05) on DMI, length time for eating(196.5 vs. 221.5 min/d), length time for rumination (351.0 vs. 449.4 min/d), efficiency of eating time(37.21 vs. 37.67 gDM/min) and efficiency rumination time (21.43 vs. 18.50 gDM/min). This researchshowed that concentrate feeding at 2% BW did not alter the efficiency of eating time and ruminationcompared to 1% BW, although able to improve BWG of OC cattle.

Abstract

This research aimed to find preventing alternative of avian influenza (AI) disease in broiler chickenby increasing body immune. Lymphocyte T would directly react to antigen presented to the cell surfaceby antigen presenting cell (APC). Th-CD4 interaction functioned to maintain Th-APC bond intactduring specific antigen activation. Fatty acid in virgin coconut oil (VCO) was potential asimmunostimulant, which therefore could increase chicken immunity through the increase of lymphocyteT and Th-CD4. This research used 40 one-day-old broiler chickens. The method applied was CompletelyRandomized Factorial Design in which the first factor was two levels of vaccine, namely groups of AIvaccinated and unvaccinated. The second factor was four levels of VCO namely 0, 5, 10, 15 mL/kg feed.Day Old Chick (DOC) were divided into eight treatment groups and repeated five times. Feed and waterwere given ad libitum for four weeks. The result showed that the number of lymphocyte and Th-CD4 inchickens given 10 mL per kg feed and vaccinated with AI was higher than that in chickens given VCOwithout AI vaccine.

Abstract

The objectives of the research were to investigate the behavior of dairy farmers and factorsaffecting the effort to enhance the economic of scale. Survey was conducted on 75 dairy farmers atGetasan District, Semarang Regency. Samples were drawn in random from villages of Jetak, Batur andTajur, 25 farmers each. The data were analyzed by logit model regression, using 15 indicators ofbehavioural approach and socio-economic factors as predictors (independent variables) i.e. ages, formaleducation, family size, experience in cattle rearing, number of cattle raised, production of milk and landoccupation. The result showed that 40.04% of the farmers were good, 33.07% were moderate and20.89% were low risk takers. The farmers’ behaviour in enhancing economic of scale significantlyinfluenced by the farmers’ age, milk production and number of cattle reared. The odds ratio of ages,milk production and number of cattle reared were 0.93; 1.32 and 1.37, respectively. These valuesindicated that as values of ages increased as much as 1 year, the values of the willingness on risk takingwill decrease as much as 0.93 times; the values of milk production increase as much as 1 litre, the valuesof the willingness on risk taking will increase as much as 1.32 times; and the values of the number ofcattle increased as much as 1 AU, the values of the willingness on risk taking will increase as much as1.37 times.

Abstract

The purpose of this research was to study genetic diversity in Indonesian sheep population usingmicrosatellite markers. A total of 18 microsatellite loci have been used for genotyping Indonesian sheep.Total sheep blood 200 samples were extracted from garut sheep of fighting and meat types, purbalinggasheep, batur sheep and jember sheep populations by using a salting out method. Microsatellite loci datawere analyzed using POPGENE 3.2 software. Based on this study obtained 180 alleles from 17microsatellite loci, while average number of alleles was 6.10 alleles (6 to 18 alleles) from fiveIndonesian sheep populations (garut sheep of fighting type, garut sheep of meat type, purbalingga sheep,batur sheep and jember sheep population). The average of observed heterozygosity (Ho) and expectedheterozygosity (He) values were 0.5749 and 0.6896, respectively, while the genetic differentiation forinbreeding among population (FIS), within population (FIT) and average genetic differentiation (FST)were 0.1006, 0.1647 and 0.0712, respectively. Genetic distance and genetic tree showed that Indonesiansheep population was distinct from garut sheep of fighting and meat types, purbalingga sheep, batursheep and jember sheep population. Based on this results were needed a strategy for conservation andbreeding programs in each Indonesian sheep population.

Abstract

The research was conducted to analyze some factors influencing production, income, farmhousehold consumption and investment of farm household beef cattle in Central Java. Five districts werepurposively chosen for research location based on the number of beef cattle population, namelyRembang, Blora, Grobogan, Boyolali and Wonogiri. Forty respondents of each district were chosenrandomly using quota sampling. Data were analyzed through Simultaneous Regression and estimated byTwo Stage Least Square (TSLS). The results showed that independent variables were simultaneouslysignificant to dependent variables (production, income, farm household consumption and investment)with the Probability F test 0.0000 and adjusted R2 were 91%; 89%; 96%; 62%, respectively. Thesimulation’s analysis of agribusiness implementation consisted of 1) decreasing 15% of service perconception, 2) increasing of beef cattle breed and number of beef cattle 15% respectively, 3) raising ofprice of rice and number of household member 15% respectively and 4) increasing of income and priceof beef cattle 10% respectively influenced to farm household consumption and investment 0.446% and5.14%, respectively, meanwhile production and income did not change. The research can be concludedthat the independent variables simultaneously significant influenced to production, income, farmhousehold consumption and beef cattle investment. The simulation of changing usage of input factor andprice significantly influenced to farm household consumption and beef cattle investment.
