Sibel Alapala Demirhan | Murat Erdem
In the present study, it is aimed to determine the current state of the goat raising businesses operating in the city of Uşak and in its provinces, their problems and to come up with suggestions for solutions to these problems. In the current study, as the sampling of the study, 132 goat-raising businesses were selected by means of stratified random sampling method and they were administered a questionnaire consisted of 83 questions. The data obtained from the analysis of the questionnaires have revealed that high majority of the goat-raisers are elementary school graduates (86.4%) and they generally raise Hair goat (89.4%). Moreover, it has also been determined that for the mating of goats, male goats are brought into the herd in September and October and this mating process occurs in the form of free insemination, the age for female goats to be used as stock is 15-18 months old, additional feeding and synchronization are not generally practiced and weaning of baby goats occurs when they are 3-4 months old. Births are usually given in February-March and milking also starts in this period and lasts 6 months on average, the lactation milk yield is 60-80 liters, milking is performed once a day with hand and the produced milk is mostly used in cheese production. Moreover, in goat raising, transhumance is not a common practice and high majority of the breeders apply regular protective vaccines. As in many other regions, many problems such as high feed prices, the difficulty in finding a shepherd and price fluctuations force goat breeders to quit. For goat raising to be sustainable, technical and economic supports given to breeders should continue and improve. If the feed can be supplied with the internal resources of the businesses and if their products can be marketed directly without using intermediaries then some of the problems can be alleviated. Putting greater emphasis on this issue and developing incentive policies will make contributions to goat raising. As a result of the present study, it was concluded that developing goat raising businesses operating mostly as small-scale family businesses in the city of Uşak to large-scale businesses where intensive production is made by providing the necessary incentives and subsides is of great importance.

This study was performed to determine the effects of the extracts of two alternative antimicrobial agents that do not harm the ecosystem (rosemary, Rosmarinus officinalis and aloe vera, Aloe barbadensis) when added to the feed of tilapia (Oreochromis niloticus) on the growth performance, proximate composition, and biometric characteristics. Rosemary extract was added to the experimental diet in ratios of 0.1%, 0.25%, and 0.5% while aloe vera extract was added to the experimental diet in ratios of 0.5%, 1%, and 2.5%. After 90 days of the feeding trial, no change was seen in the weight increase, specific growth rate, feed conversion ratio, condition factor, hepatosomatic index, or viscerosomatic index of the tilapia. The fact that proximate analyses did not differ between groups showed that the plant extracts did not adversely affect the health status of tilapia in the ratios used in this study. As a result, the addition of 0.1%, 0.25%, and 0.5% rosemary extract and the addition of 0.5%, 1%, and 2.5% aloe vera extract to tilapia feeds did not cause changes in the growth performance, biometric indexes, or chemical composition findings of the fish meat.

In breeding for drought tolerance, availability of precise, cheap and easy to apply selection tool is critical. The aim of the present study was to identify potential screening tools that are useful for selection of drought tolerant genotypes in potato and select drought resistant potato genotypes. The study assessed sixty clones arranged in a 10×6 alpha lattice design with two replicates in a managed stress experiment. Two irrigation treatments were applied: fully watered non-stress and terminal drought, where the irrigation water supply to the crop was withheld after 50 % flowering to induce post-flowering stress. Stress indices were calculated based on tuber yield of genotypes in both stressed and non-stressed conditions. Identification of drought tolerant genotypes based on a single index was less informative as different indices identified different genotypes as drought tolerant. Hence, to determine the most desirable drought tolerant clones rank sum of indices, correlation, and bi-plot display of the principal component analysis was employed. The indices modified stress tolerance index based on non-stressed yield, Men productivity, Geometric mean productivity, Stress tolerance index, Harmonic mean, modified stress tolerance index based on stressed yield and Yield index exhibited strong association with both yield under stressed and non-stressed yield. These indices discriminated drought tolerant genotypes with higher tuber yielding potential both under stress and non-stress conditions. Genotypes CIP-398180.612, CIP-397069.5, and CIP-304371.67 were identified as drought tolerant. These genotypes could be potentially grown both under drought prone and potential environments and these selection attributes could help to develop climate resilient potato varieties.

Didar Ucuncuoglu
Ensuring the olive oil quality and authenticity has become a great importance for both traditional and emerging olive oil producing countries. The chemical composition in olive oil heavily varies depending on the olive cultivar and its growing region, the agronomic applications, the olive oil production methods and the process and storage conditions. With the help of some analytical techniques and data evaluation methods, it is possible to grade olive oils in terms of their differences. This research examines particularly fatty acid composition of commercial olive oils (2017/2018 season) with mass detector coupled with gas chromatography (GC/MS). Results were evaluated for grading of them according to IOC regulations based on cultivar (ripe or unripe Ayvalik and Memecik), production (organic, stone mill, cold press, two or more centrifugation systems, filtered or unfiltered) and packing type (transparent or dark glass bottle and plastic bottle), and also their geographic origin (Ayvalik and Edremit towns, the Cunda Island, North Aegean region or South Aegean Region). According to overall data processing, virgin olive samples could be successfully distinguished in terms of theirs geographic origin and cultivar roots. Moreover, it was also explained that the effect of process and package type for grading of olive oils as ‘extra virgin’ or ‘virgin’.
