The present study was aimed to investigate the genetic diversity among 17 Turkish water buffalo populations. A total of 837 individuals from 17 provincial populations were genotyped, using 20 microsatellites markers. The microsatellite markers analyzed were highly polymorphic with a mean number of alleles of (7.28) ranging from 6 (ILSTS005) to 17 (ETH003). The mean observed and expected heterozygosity values across all polymorphic loci in all studied buffalo populations were 0.61 and 0.70, respectively. Observed heterozygosity varied from 0.55 (Bursa (BUR)) to 0.70 (Muş (MUS)). It was lower than expected heterozygosity in most of the populations indicating a deviation from Hardy–Weinberg equilibrium. The overall value for the polymorphic information content of noted microsatellite loci was 0.655, indicating their suitability for genetic diversity analysis in buffalo. The mean FIS value was 0.091 and all loci were observed significantly deviated from Hardy–Weinberg Equilibrium (HWE), most likely based on non-random breeding. The 17 buffalo populations were genetically less diverse as indicated by a small mean FST value (0.032 ± 0.018). The analysis of molecular variance (AMOVA) analysis indicated that about 2% of the total genetic diversity was clarified by population distinctions and 88 percent corresponded to differences among individuals. The information produced by this study can be used to establish a base of national conservation and breeding strategy of water buffalo population in Turkey.

Bu çalışma, suda ekstrakte edilen propolisin (PE) kaplama materyali olarak kullanımının raf ömrü, depolama sıcaklığı, süresi ve serbest dolaşan yumurtacı tavuklardan elde edilen yumurta kalitesi parametreleri üzerindeki etkilerini ortaya koymak amacıyla yapılmıştır. Yumurtanın tazeliğini daha uzun süre koruyabilmek için bir ürünle kaplama düşüncesi, uzun zamandır araştırmacıların inceleme konusu olmuştur. Bu amaçla uygulanabilecek kaplama malzemelerinden birisi olan propolisin, farklı alkoller kullanılarak ekstrakte edilmiş örneklerinin kullanıldığı çalışmalar bulunmaktadır. Bu çalışmada serbest dolaşan tavuklardan elde edilen yumurtaların, suda ekstraksiyon yöntemi ile elde edilmiş PE ile kaplanması ve farklı depolama koşullarında bekletilmesinin, yumurta iç ve dış kalite parametreleri üzerine olan etkileri araştırılmıştır. Bu amaçla 64 haftalık Lohmann kahverengi yumurtacı tavuklardan 80 adet yumurta toplanmıştır. Yumurta örnekleri, 8 muamele [2 saklama süresi (10 ve 20 gün) × 2 saklama sıcaklığı (4°C ve 22°C)× kabuk üzerinde propolis kaplama (kaplamalı/kaplamasız)] grubuna ayrılmış ve her bir muamelede 10 yumurta olacak şekilde düzenlenmiştir. Araştırma sonunda PE’nin, kabuğun üzerindeki porları kaplaması sebebiyle, oda ve buzdolabı sıcaklığında depolanan yumurtaların raf ömrü ve iç kalite özellikleri üzerinde olumlu etkilere sebep olduğu görülmüştür. Propolis ekstraktı ile kaplama sonucunda özgül ağırlık, yumurta sarısı indeksi değerleri artış göstermiştir (P

The aim of this study is to convert the fleeces obtained after 1 year of maintenance of the Karacabey (Turkish) Merino fleece-oriented starter flock of Turkey, which was established in Tekirdağ Namık Kemal University Faculty of Agriculture Education Research and Application Farm, into worsted yarn and then woven fabric for the first time in Turkey after wool washing. Thus, it is aimed to show that the same worsted men's suit woven fabrics normally produced with Australian merino wool can be produced with Turkish merino. The structural, mechanical, handle and comfort properties of the produced fabric after dyeing-finishing processes were compared with the fabric produced with Australian merino by taking the fabric produced with Australian merino as reference. In the performance tests conducted, it was determined that the fabric produced with local-national wool showed similar quality performance properties to the fabric produced with Australian merino and the first men's suit jacket production was achieved from this fabric obtained from our local wool.
