Abstract

This study was conducted to determine the effect of various calcium and phosphorus levels on theproduction performance of Bantul Duck. A total of 270 female ducks, 26 weeks age, were used in thestudy with a 3x3 factorial treatment, which is a combination of three levels of Ca: 3.75; 3.25 and 2.75%and three levels of P: 0.45, 0.35 and 0.25%. Each treatment occupied three replication cages, each ofwhich consisted of 10 ducks. The experiment was conducted for 12 weeks.. Data recorded were: (a) feedintake (g/duck/day), (b) egg production (% HDA), and (c) feed conversion. All quantitative dataobtained during the study were analyzed by analysis of variance (ANOVA) using SPSS computerprogram. The results of the variables recorded did not show significantly difference. Increasing Ca levelon feed showed an increasing trend of egg production. The average feed consumption ranged at 151-159g/duck/day; egg production was 75-84%, and the feed conversion was 184-212 g/egg.

Abstract

The present study was undertaken to identify factors that influences biosecurity adoption on layinghen farmers in Sidrap district, South Sulawesi. This district was choosen because beside it was famousas the center of laying hen farms, it was also as one of districts in South Sulawesi which suffered fromAvian influenza outbreak. Total samples were 60 respondents. The samples were choosen throughstratified random sampling from two subdistricts which had the most populous of layer smallholders,namely Baranti and Maritengngae. Data were obtained through observations and interviews using aquestionnaire. Data were analyzed using a score based on biosecurity status. Biosecurity status wasobtained based on the adoption of biosecurity measures which consisted of 9 stages: farm inputs, trafficonto farms, distance from sources of pathogens to shed, exposure of farm, biosecurity at farm boundary,biosecurity between farm boundary and shed, biosecurity at the shed door, traffic into the shed andsusceptibility of the flock. Multiple regression model was employed to analyze the data. The studyrevealed that the adoption biosecurity were associated with gender, age, education, farming experience,farm-income, family size and social capital. These variables contributed 20% variation in biosecurityadoption of laying hen farms. However, only farm income, family size and social capital were the majorfactors influencing to the adoption of biosecurity (P<0.05).

Abstract

The research was aimed to evaluate the performance of laying hens fed different calcium sources.Two hundreds of Isa Brown laying hens were used in this study. The hens were raised in individualbattery cages units for 12 weeks. Four calcium source (limestone as a control, 5% limestone + 2.5%eggshells waste, 2.5% limestone + 5% eggshells waste and 7.5% eggshell waste) were used in feedexperiment. A completely randomized design was applied, with 4 treatments and 5 replications. Eachexperimental unit consisted of 10 laying hens. The parameters measured were feed intake, proteinintake, calcium intake, phosphorus intake, egg production, egg weight and feed conversion ratio. Resultsof the research showed that the calcium source had significantly effect on performance productions. Theuse of eggshell waste 7.5% significantly increased the feed intake, calcium intake, phosphorus intake,egg production and egg weight except for feed conversion ratio. The conclusion of this research was thatthe use of eggshell waste as calcium source of feed resulted in better performance than using limestoneor mixed limestone with eggshell waste.

Abstract

High occurrence of aflatoxin contamination in feed stuffs implicates for a long time experience ofaflatoxin B1 (AFB1) exposure to dairy cattle in Indonesia. A latin square 4X4 research design wasadopted to study the characteristic of AFB1 carry-over rate (COR) of Indonesian crossbred FriesianHolstein (PFH) as effects of inclusions of AFB1-naturally contaminated feed and bentonite in the diet.Results showed a rapid aflatoxin M1 (AFM1) excretion in the milk, detected in the first milking sampleor 10 hours after AFB1 ingestion. The steady state of AFM1 concentration observed since the first dayof treatment period and AFM1 contamination was still detected until 5 days after AFB1 removed fromthe diet. The COR in this study was observed 0.1%. AFM1 concentration was highly significantly(P<0.01) affected by treatments. However, there were no significant effects (P>0.05) of levels of AFB1and bentonite inclusions on the COR, nutrients intake, milk production, and milk composition. IIt isconcluded that AFM1 concentration was influenced by AFB1 intake and that transfer of AFB1-feed intoAFM1-milk (COR) in PFH cow was lower compare to reported COR value for dairy cow in sub tropicalregion.

Abstract

The aim of the present study was to conduct univariate, bivariate and multivariate (principalcomponent analysis, PCA) approaches in the screening of tannin-containing plants from variouscollection sites for their CH4 mitigating properties. Plant samples were obtained from various collectionsites in different countries, i.e. Indonesia (n = 27 species), Mongolia (n = 14), Switzerland (n = 16) andGermany (n = 3). The plants were incubated in vitro with buffered-rumen fluid at 39oC for 24 h. Totalgas production was recorded as an indicator of feed quality and emission of CH4 was measured. Resultsshowed that, based on bivariate screening, generally, plants possessed low CH4 production had lowquality or low total gas production except Rhus typhina, i.e. 43 ml/200 mg DM. The loading plot of PCAshowed that all phenolic fractions were in the opposite direction with CH4 and total gas production.Plants clustered together in reverse direction to that of CH4 were Bergenia crassifolia root and leaf,Swietenia mahagoni, Clidemia hirta, Peltiphyllum peltatum, Acacia villosa and R. typhina. It wasconluded that, for tannin-containing plants, screenings based on univariate, bivariate and multivariateapproaches in relation to ruminal CH4 emission led to similar results.

Abstract

The study was conducted to evaluate forage productivity of arbila (Phaseolus lunatus) as theruminant feed at various levels of rhizobium inoculants and harvesting times, was designed followingcompletely randomized design of factorial pattern with two factors. The first factor was the level ofinoculums (I) i.e. I1 (without inoculum), I2 (5 g/kg seed), I3 (10 g/kg seed), and I4 (15 g/kg seed). Thesecond factor was harvesting time (U) i.e. U1 (60 days), U2 (80 days), U3 (100 days) with 4replications. The variables were N uptake, production of dry matter (DM) and organic matter (OM), andpercentage of OM, crude protein (CP), crude fiber (CF), nitrogen free extract (NFE), extract ether (EE)and ash of arbila forage (based on DM). The results showed that inoculant treatment at the rate of 15g/kg seed produced the highest percentage of effective nodules (98.72%), and in combination withharvesting age at 100 days each polybag of plant was able to absorb the higest amount of N (688. 10 g)with production of DM 273.81 g, OM production 263.96 g and nutrients content based on DM of about91.14% OM, 33.52% CF, 34.76%, 5.75% EE, 09.37% ash, and 16.16% CP. From the study, it can beconcluded that arbila plants inoculated specific rhizobium Phaseolus vulgaris at the rate of 15 g/kg seedand harvested at 100 days yielded the best forage as feed.
