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

This research was conducted to determine the resistance degree of lactic acid bacteria (LAB) isolated from the faeces of broilers towards various intestinal conditions, in order to select a lactic acid bacteria to be used as prospective probiotic.  Ten types of LAB bacteria  (M1, M2, M3, M4, M5, M7, M8, M23 ,M26, and M28) isolated from the faeces of broiler chicken were subjected to pH2, pH3, and pH4; to 3% bile salt and to the temperatures of 30oC, 37oC and 41oC. The results of the research showed that all LAB isolates experienced the highest colony reductions at pH2, which was  around 3.2-5.5 log units/ml. The reduction of colony numbers at pH3  was approximately 1.8-3.1 log unit/ml, and the reduction at pH4 was around 1.0 – 2.5 log unit/ml. All the LAB isolates experienced a decrease of 0.5 log unit/ml to 1.6 log unit/ml  in colony numbers after bile salt exposure. The reduction of colony numbers  of ten LAB isolates at the temperatures of 30oC, 37oC and 41oC was 0.6 - 1.4 log unit/ml ; 0.1 – 0.5 log unit/ml and 0.7 – 1.4 log unit/ml, respectively. None of the ten  isolates posses all of the expected characteristic, however based on its more superior ability to block the pathogenic micro-organism as well as its ability to survive in simulated gastro intestinal tract conditions, M1 was selected as prospective probiotic.

Abstract

One factor affecting productivity of bali cattle is availability of good quality forages. Based on that reason, Australian Centre for Internatioanal Agriculture Research (ACIAR) in cooperation with Hasanuddin University and BPTP of South Sulawesi funded a program with an aim to improve forage management for bali cattle in South Sulawesi. This activity was carried out under farm condition involving sixty “best-bet” farmers in twelve villages across three districts (Barru, Bone and Gowa). Aspects evaluated in this program were utilization of existing forages and  utilization of new forages by the farmers. In addition, sufficiency of forage for the cattle of best bet farmers was also evaluated. The results indicated that before implementation of ACIAR program, the average proportion of forage used by the farmers to feed on the cattle was 43.4% elephant grass, 34.4% native grass, 12.6% peanut straw/maize stover, 9.1% rice straw, and 0.7% tree legumes. After program implementation, there was a change in the proportion of forage for cattle, namely  47.3% elephant grass, 13.4% native grass, 12.4% peanut straw/maize stover, 12.3% rice straw, 4.1% tree legume leaves.  Proportion of some new forages used by the farmers was 2.1% setaria,  2.5% mulato, 5.1% paspalum, and 0.9% panicum. In conclusion, there was a different in the proportion of forages used by the farmers to feed on the cattle before and after project implementation, in which the proportion of elephant grass and tree legume leaves increased and decreased in the use of native grass, while use of agricultural byproduct was relatively stable. In terms of utilization of new grasses introduced, paspalum was the most popular grass for best bet farmer to feed on the cattle.

Abstract

The aim of this study was to determine the role of some marketing agencies in selling eggs of layer farmers in Indonesia. The research was conducted in West Java, Bali and South Sulawesi. The selection of those regions was based on the category that they had the most populous layer farmers compared to other regions. The number of respondents was determined using quota sampling method from FAO poultry industry data, i.e. 60 layer farmers of West Java and South Sulawesi respectively, and 41 farmers of Bali. The farmers involved in the study were those having layer population between 2000-5000 hens. Data were collected from the respondents through deep interview using a questioner that have been prepared before hand and conducted in May 2010.  The results of the study indicated that among the marketing agencies studied in the three regions; West Java, Bali and South Sulawesi, the role of whole sellers in eggs selling of layer farmers was the most important one, followed by restaurants, traditional markets, consumers and the poultry shop, respectively. In terms of egg selling price in the three regions, the most expensive was in Bali and the cheapest one was in South Sulawesi.
