Günümüz koşullarında, hayvancılık işletmelerinin ve işletmecilerin karşılaştığı en büyük sorunlardan biri, işletme kapasitesini büyütmek için nitelikli ve güvenilir iş gücü temini ve bunun getirdiği maliyet sorunlarıdır. Buna paralel olarak yem hazırlama ve dağıtımı ile ilgili iş gücü, zaman ve maliyet sorunları da işletmeler için önem taşımaktadır. Hayvancılıkta yemleme işlemi günlük çalışmalar içerisinde önemli bir yer tutar. Kullanılan yem, bunun sevki ve idaresi hayvan sağlığını ve işletme verimini etkileyen en önemli faktörlerdendir. Bu çalışmada, durumun önemi göz önüne alındığında, yem hazırlama ve yem dağıtım ile ilgili iş gücü, zaman ve sürü yönetimi sorunları için çözüm olabilecek ve ülkemizde kullanımı yaygın olmayan ve henüz tanınmayan yemleme robotu hakkında operasyon bilgileri verilmiş, sürü yönetimi üzerine etkileri belirlenmiş ve geleneksel yem hazırlama ve dağıtma sistemleri ile karşılaştırılması sonucunda iş gücü ve zaman analizleri yapılmıştır. Özellikle yüksek kapasiteli işletmelerde, yemleme robotu aracılığıyla sağlanan otomasyonun klasik sistemler ile karşılaştırıldığında iş gücünden %75 oranında, zaman girdisi konusunda ise 13,75 kat tasarruf olanağı çıkan sonuçların en önemlilerindendir. Bunun yanı sıra modern işletmelerde kullanılan süt sağım robotu gibi diğer otomasyon içeren işler için de bir destek unsuru ve sürü yönetimi olarak bütünleyici bir etkisi olduğu çıkan diğer bir önemli sonuçtur.

In the province of Tokat Turkey has an important place in terms of agricultural fertilizers and manure in order to demonstrate the environmentally conscious manufacturer 88 were interviewed. It was observed that the producers interviewed within the scope of the research are in the age range of active working age and have a socio-economic structure that makes a living from agricultural income. Factors such as age / education have a great impact on the economic structure as well as on production. Since income will be the biggest indicator of the economic structure, the income status of the producers has been investigated. Annual average agricultural income of producers is 22,311.36 TL, while non-agricultural income is calculated as 24,886.32 TL. Thus, it can be said that the average annual income of the producers is 47,197.68 TL. Here is what producers think about the residue after using the fertilizer; 48.86% of them thought that there would be manure residues and that it would have a negative impact on the environment, 43.18% of the manure would accumulate in the soil and underground water sources, 15.91% of the manure would be washed away in various ways, 11.36% had no idea about the manure residue and 6.82% that some fertilizers will leave residue in the soil. When the econometric relationship between the type of producer (the producer who only farms and works in non-agricultural insured work) and the idea that the fertilizer will accumulate in the soil and groundwater resources, it was determined that there is a significant and positive relationship. In other words, it can be said that producers have knowledge about the factors that cause environmental pollution. However, it continues to fertilize unconsciously without thinking that environmental pollution will harm them over time. This result once again highlights the importance of the training need.

The aim of study is to investigate; the effect of increasing several doses P application on soil C, N and P concentration in Long term experiment conditions. Tested hypothesis; increasing P doses application increases soil C, N and P concentration, consequently plant yield can increase. The experiment has establish at University of Çukurova, Faculty of Agriculture, Research and Application field on Arık soil series from since 1998 until update. Four doses of P applied; such as 0 kg P2O5 ha-1 (P0), 50 kg P2O5 ha-1 (P50), 100 kg P2O5 ha-1 (P100) and 200 kg P2O5 ha-1 (P200) with tree replications. Under rain fed condition Adana-99 species wheat (‎Triticum aestivum L.) seeds were sown in November 2017 and harvested at May 2018. Soil samples were taken at different depth (0-15 cm and 15-30 cm) of rhizosphere and non-rhizosphere part at harvest. Soil P concentrations, organic C (OC), inorganic C (IC), soil total carbon C and N were analyzed. Result shown that there is a statistically difference as P concentration, especially in both depth of rhizosphere and non-rhizosphere soils, the best application is P200 compared to the control. As the P dose increased, also soil P content increased linearly. In terms of soil OC content, there was a statistically significant difference at a depth of 15-30 cm in rhizosphere and non-rhizosphere soils and, the best practice was got at P200 application compared to control treatment. In addition, due to increasing doses of P application, the mean soil OC, total N and C content increased. The founded results are support our hypothesis.

Biocomfort conditions, which are related to climate parameters, are a factor that affect almost every aspect of people’s lives. Compatibility in terms of biocomfort also brings many advantages and disadvantages in areas where tourism activities are carried out. For this reason, it is of great importance to identify areas that are suitable and not suitable for biocomfort during the tourism season, especially in areas where tourism activities are carried out. In this study, with the help of GIS, it was aimed to determine the areas that are suitable and not suitable for biocomfort in the city of Samsun in June, July, August and September by using the summer temperature index (Summer Simmer Index = SSI). As a result of the study, it was determined that 1.41% of the province in June and 16.65% in September remained in the cold zone. Apart from this, it was determined that 11.58% of the province in June, 33.27% in July, 21.77% in August and 14.3% in September remained in the second generation, which is considered the most comfortable belt.

The increase in consumers' demands for safer and healthier food has led to the development of many new products in food technology. For this reason, micro- or nanoencapsulation has become an important area in order to protect food components with functional properties against environmental conditions and to provide controlled release in recent years. As a matter of fact, many encapsulation techniques have been developed and many different active materials have been encapsulated. Nanoemulsions, a nanoencapsulation technique, are the process of encapsulating core material in two immiscible liquids. Nanoemulsions have higher stability and loading capacity compared to normal emulsions. It also increases the bioavailability of the core materials because of the increased absorption of the active material in the digestive tract. In this review, the required materials for nanoemulsion preparation, the nanoemulsification methods, and the studies on the encapsulation of various food components in nanoemulsions have been reviewed.

The major antimicrobial proteins in donkey milk are lysozyme, lactoferrin, lactoperoxidase and immunoglobulins. Lysozyme has an important role in the host defense by way it inhibits the pathogenic bacteria. The aim of this study is to investigate the Lysozyme (LYZ) gene polymorphism in 82 donkeys reared in Thrace region of Turkey. 716 bp long partial 5’ UTR, exon 1, intron 1, exon 2 regions of LYZ gene were amplified and PCR products were analyzed via DNA sequencing. Three novel single nucleotide polymorphisms (SNPs) were identified as g.1782775A>G, g.1782924A>G and g.1782960T>C in the first intron of LYZ gene. The partial DNA sequence of LYZ gene in donkeys was reported in the present study and sequences of LYZ were entered to NCBI Genbank database with the accession number: MK984689-MK984692. This SNP may have an effect on immune system and milk traits in donkeys and additional studies are needed to confirm this assumption for donkey breeding.

Progesterone plays a key role in the establishment and maintenance of pregnancy in mammalian. Increasing levels of circulating progesterone in the post-conception period are associated with conceptus elongation and high pregnancy rates in cattle. Contradictory results are available on the direct role of progesterone in early embryo development. The objective of this study was to evaluate direct effects of progesterone on in vitro development of cattle embryos. Immature oocytes collected from slaughtered animals and cultured in the presence of different concentrations of progesterone (25, 50, 100 ng/mL) following in vitro fertilization. Cleavage rates in 25 and 50 ng/mL concentrations of progesterone were significantly higher than those in controls and 100 ng/mL. Rate of embryos that reached to the morula stage was similar in all groups. Supplementation of 25 and 50 ng/mL progesterone to the culture media significantly increased blastocyst yield while 100 ng/mL progesterone resulted in a decrease. As a conclusion, we can suggest that progesterone supplementation in in vitro culture may support embryo development at low levels.

This study aimed to reveal relationship between the extensiveness of trichophytosis on the body and serum zinc levels in cattle. This study was carried out on 92 cattle with trichophytosis and 50 healthy ones. Serum zinc levels of healthy cattle were evaluated as control. The cattle with trichophytosis separated into 5 groups according to diffusiveness of the diseases. Experimental groups of this study were designed as follows; Group 1: up to 1 cm, Group 2: 1-5 cm, Group 3: 5-10 cm, Group 4: 10-20 cm and Group 5: widespread on the body. Serum zinc levels measured by atomic absorption spectrophotometer equipped with flame system. In general, the mean level of Zn in trichophytosis groups (0.613±0.013 mg Zn/L) was statistically lower than healthy ones (0.900±0.017 mg Zn/L). A negative correlation was determined between the diffusiveness degree of trichophytosis and serum zinc levels (r = -0.772). Serum Zinc levels were statistically decreased from the control group to group 3. However, a stable course was observed from 3 to 5. Therefore, the value of group 3 (0.6 mgZn/L) was determined as a critical value for the cattle with trichophytosis. According to regression analysis results, it was observed that the extensiveness of the trichophytosis lesions affected the levels of serum Zn levels significantly (r2=59.6%). Consequently, serum zinc levels of cattle decreased in an inversely proportional manner to the diffusiveness degree of trichophytosis and stabilization was observed at the level of 0.6 mg Zn/L.

In this study, it was aimed to determine the effects of gibberillic acid (GA3) applications on drop and quality changes of fruits on-tree storage period. GA3 (before peel color break, on the peel color break and both periods) and 20 ppm GA3 (before peel color break and on the peel color break) were applied to the trees, and the untreated trees constituted the control group. Fruits were harvested in five periods at monthly intervals from april. In the last harvest period, the average fruit drop rate was significantly higher in the control group (38.48%) than in the color transformation 10 ppm GA3 (9.44%) and before color transformation 20 ppm GA3 (19.28%). The fruit drop was not observed in the first and second harvest periods. Especially in the first period on-tree storage, the shell C* and h° values of the fruits in control were found higher than the GA3 application. As a result, twice application of 10 ppm GA3 in 'Valencia Late' orange reduced pre-harvest fruit drop, delayed peel color transformation and limited fruit quality change. Accordingly, it has been revealed that it allows on-tree storability until the end of august.

Erwinia amylovora, the causative agent of fire blight disease, threatens a lot of species of the Rosaceae family. Antibiotics and copper compounds in chemical applications are most frequently are applied, but these can be phytotoxic and cause resistant strains of the pathogen. In our experiments, 20 herbal materials were tested for their antimicrobial effectiveness against the fire blight pathogen in vitro and in planta. The air-dried plants ground into fine powder and extraction was performed at room temperature by maceration with 80% (v/v) methanol/distilled water. The minimum inhibitory concentration values were determined by using disc diffusion method and streptomycin was used as control in all experiments. Antimicrobial activity was evaluated by measuring the inhibition zones in reference to the pathogen. Among the tested plants, Szygium aromaticum, Thymus vulgaris and Rhus cararia showed a good antibacterial activity and they inhibited the growth of E. amylovora with inhibition zone diameter ranging from 21 to 27 mm at 20% (w/v) in absolute methanol compared to streptomycin (31 mm) in vitro conditions. In vivo tests were performed by using highly virulent E. amylovora isolate (Eak24b, 91%) grown on TSA medium and inoculation on young shoots of 3-year-old Gala variety of apple and Santa Maria variety of pear seedlings at 107 CFU ml-1 density of the pathogen. Disease severity (%) was assessed by by proportion of blighted shoot length to the whole shoot length and also efficacy of the extracts was determined by using Abbott formula. The highest efficacy was obtained by S. aromaticum and T. vulgaris extracts of reducing shoot blight of cv. Gala and cv. Santa Maria by 67.81% - 64-12% and 51.50% - 51.04% ratios, respectively. Obtaining results showed that some medicinal and aromatic plant extracts might be used against fire blight disease as potential new generation chemicals on pome fruits within integrated and organic control programs.
