Ayşe Özge Demir | Ferda Karakuş | Suna Akkol
The aim of this study was to determine the some serum minerals and their interactions between in 2, 3 and 4 years-old healthy Norduz (n=45) and Hair (n=31) goats raised in semi-intensive conditions. Mineral levels were determined with Atomic absorption spectroscopy (AAS) in ppm level. Results were calculated as Fe 1.578±0.088 and 1.379±0.095 mmol/L, Cu 1.300±0.067 and 1.303±0.080 mg/L, Zn 0.972±0.029 and 0.937±0.029 mg/L, K 4.574±0.091 and 2.102±0.074 mmol/L, Mg 2.089±0.057 and 4.670±0.098 mmol/L, Mn 2.163±0.152 and 2.215±0.198 mg/L, Pb 0.078±0.005 and 0.087±0.006 mg/L for Norduz and Hair goats, respectively. While the differences in the mineral levels of hair goats were not significant, significant differences has been found between the age groups in terms of K, F and Pb in Norduz goats. In addition, while there was no statistically significant difference between 3-year-old goats, statistically significant differences hs been found for Fe and 2-year-old goats K and Mg in 4-year-old goats. Moreover, with respect to correlation coefficients, positive correlations were obtained both between K-Mg at Norduz goats and between Fe-Cu, Fe-K, Fe-Mg, K-Mg at Hair goats in all years-old groups.

Turkey has an advantageous position for the cultivation of ornamental plants for reasons such as favourable conditions, proximity to markets and cheap labour. In addition to classical production methods, biotechnological methods are used to meet the demand of Spathiphyllum, which is an indoor plant. In recent years, it has been started to be used in micropropagation of plants called temporary immersion system as well as classical tissue culture systems. Within the scope of the present study, micropropagation and rooting studies were carried out using classical tissue culture system and Plantform, one of the temporary immersion bioreactor systems, in the commercially important Spathiphyllum ‘Chico’ genotype. MS medium containing 1 mg L-1 6-Benzylaminopurine (BAP) was used in micropropagation experiments established in both systems, and Murashige and Skoog (MS) medium containing 1 mg L-1 Indole-3-butyric acid (IBA) was used in rooting experiments. The results of micropropagation and rooting have been found to be successful in both systems. As a result of the screening with Sequence-Related Amplified Polymorphism (SRAP) markers, it was determined that there were no genetic differences in the plants that were reproduced and rooted.

Orhan Yavuz | Güngör Çağdaş Dinçel
Pneumonic Pasteurellosis (PP) is an infectious disease caused by Pasteurella multocida and Mannheimia haemolytica, mostly observed in cattle, sheep and calves. PP is characterized by fibrinous bronchopneumonia and pleuritis in the lungs. In this study, it was aimed to determine Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase expressions by immunohistochemical methods in the lungs suffered from PP. For this purpose, twenty lung tissues were collected from calves with PP. For the Control Group, ten lungs of calves were collected from Aksaray Slaughterhouse. After necropsies of calves were confirmed to be PP by bacteriological examinations. Then the routine histological process was performed to tissues, and stained by Hematoxylin & Eosin for histopathology, and Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase antibody staining for immunohistochemistry. The immunohistochemical findings indicated that Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase positive reactions were seen in alveolar, bronchial and bronchiolar epithelia, and desquamated inflammatory cells in the lumens. In addition, the peripheral neural extensions were immunopositive for neuronal nitric oxide synthase and vascular endothelial cell were positive for inducible nitric oxide synthase. The findings can contribute to a better understanding of expressions of molecules such as Caspase and nitric oxide synthase. These results show that apoptosis and nitric oxide synthase expressions have triggered by airway epithelia and inflammatory cells in the lungs with Pneumonic Pasteurellosis in calves.

The aim of this study was to determine the socio-economic structures of dairy cattle farms and feed usage in dairy cattle sector in the Mediterranean Region provinces (Adana, Osmaniye, Mersin, Hatay, Kahramanmaraş) of Turkey. According to the results of the research, it was determined that the family sourced labour force was used at a higher rate than the foreign labour force during dairy cattle production activities. It was found that forage crops were produced in 62% of the farms where silage maize, alfalfa, barley and vetch covered the highest acreages, respectively. A large proportion of the enterprises was possessor of milking machines (85.81%). It was determined that, as the size of the farm increases, the roughage usage increases compared to concentrate feed.

Sweet cherry (Prunus avium L.) is highly valued fruit in the world and has wide production area in Turkey. Some of the species from the family Cicadellidae can cause direct damage by sucking the sap, and indirect damage by transmitting the phytoplasmas during their feeding process on the sweet cherry trees. This study was conducted to investigate the presence of the species of Cicadellidae family in Adana (Pozantı), Niğde (Darboğaz) and Kahramanmaraş (Andırın and Central Town), where sweet cherry cultivation is carried out, through 2014-2016. Surveying was done in two period a year, in spring (May-June) and fall (October-November) on the trees and weeds. As a result of sampling, 55 species from 35 genus in Cicadellidae were found. They are 32 species from Deltocephalinae subfamily, 18 species from Typhlocybinae, 4 species from Agallinae and 1 species from Megophthalminae subfamily were identified. Among them, Psammotettix striatus (Linnaeus) was the most common species with the 45.79% in total, followed by P. provincialis (Ribaut) with 15.26%. The other species were Empoasca sp. and Asymmetrasca decedens (Paoli) with 7.15% and 6.63%, respectively. It is known that the Phytoplasmas are phloem-limited agents, so, the cicadellid species that are feeding phloem tissue of the plant can acquire the pathogen and be able to transmit the phytoplasma potentially. As a result, it could be concluded that studies are needed to determine the potential to be vector of species of Deltocephalinae determined in sweet cherry orchards.

In this study, we compared the growth and survival characteristics of Romanov × Morkaraman (F1 Rom), Romanov × F1 Romanov (G1 Rom) and Charollais × F1 Romanov (Charom) crossbreed lambs weaning weight at different ages. After birth, from three genotypes lambs were weaned at two different ages of 50 and 75 days and growth performance after weaning was examined at 120 days of age. The effect of three different genotypes and birth type on birth weight was very important, and sex effect was insignificant. In weaning weight, only the effect of birth type was found to be significant. Lamb birth and weaning weights were in Charom, F1 Rom, G1 Rom lambs, 3.38-15.28; 3.98-15.04; 3.21-15.55 kg, respectively. The type of birth showed variation in the birth weight of the lamb and the decrease in lamb birth weights (Single: 4.19 kg: Twin: 3.42 kg; Triplet: 3.15 kg and Quadrature: 2.88 kg) was observed as the number of offspring increased. The effect of the birth type on weaning weights was similar in single and triplet. Single-born lambs have higher weaning weights than those of twins and quadruplets. Average daily live weight gain (ADG) from weaning in single lambs, 247.37 g were found higher than twin (190.67 g), triplets (201.44 g) and quadruplets (178.57 g). The effect of weaning age was insignificant on weaning weights. The first month weight after weaning, effect of the genotype of the lamb, the birth type and the sex were insignificant; but effect of weaning age was significant weaning weights and first month after weaning weights the ADG. The late weaned lambs had higher next first month live weight (18.62-17.89 kg) and ADG (179.45-81.32 g). The live weights of the lambs on the 120 days were similar and none of the factors investigated were found to be effective.

Cemil İşlek | Bengü Türkyılmaz Ünal | Sinan Aydın
The amount of secondary metabolites can be increased with different elicitor applications in vitro. It has been determined that zinc sulphate significantly increases the amount of capsaicin in the cell culture of red hot pepper. It is important to determine how the metal applied as elicitor will have an effect on plant metabolism. In the study, it was aimed to determine the effects of zinc sulphate (ZnSO4) applied to the cell suspension cultures of pepper seeds at different concentrations (0.1 M, 0.2 M, 0.4 M) and for periods (24, 48, 72 hours) on the total protein and phenolic substance amounts, and superoxide dismutase-peroxidase enzyme activities of pepper calluses. It was observed that the amount of protein increased, superoxide dismutase and peroxidase enzyme activities decreased, and the total amount of phenolic substance increased especially in 72 hours of treatment where zinc was applied as elicitor. These results show that ZnSO4 can be used as an abiotic elicitor in plant cell culture media.

Mansur Seymen Seğmenoğlu
Milking is a source of change in milk yield and milk quality determination, and one of the main events of milking is the oxytocin-mediated ejection reflex. Complete ejection of milk from the udder is due to the presence of high oxytocin during milking. The aim of this study is to investigate whether oxytocin administered intramuscularly has an effect on increasing milk ejection. In the study, 28 clinically healthy lactation Holstein cows were used, the lactation numbers and lactation periods of these cows were ignored in the evaluation. The study groups are divided into four groups, each consisting of seven cows. 50 IU oxytocin was given to group-1 five days before milking in the morning and evening, group-2 received 50 IU oxytocin once a day just before milking and the group-3 was given 50 IU oxytocin once before morning milking on the 1st, 3rd, and 5th days and the group-4 is a control group, oxytocin was not given to this group. Oxytocin injection was administered intramuscularly 30 minutes before milking. In the evaluation, the last five days of milk data before the application, five days of milk data during the application period and five days of milk data after the application period were taken into consideration. As a result of the study, we can say that the udder was not completely emptied with the intramuscular administration of oxytocin.

2018 yılı verilerine göre Çanakkale ili Türkiye kanola üretiminde %7,5’lik pay ile 5. sırada yer almaktadır. Bu çalışmada, araştırma alanı olarak belirlenen Çanakkale ilinde, 2018 yılında kanola üreten ve Tam Sayım Yöntemine göre tespit edilen 83 işletmeden elde edilen veriler yardımıyla, kanola üretiminde kullanılan girdilerin miktar ve parasal değer bakımından işletme büyüklük grupları arasında farklılık olup olmadığının tespit edilmesi amaçlanmıştır. Elde edilen analiz sonuçlarına göre; birim alana kullanılan girdilerin bedelleri arasında sadece ilaç girdisinin işletme büyüklük gruplarına göre %5 düzeyinde, birim alana kullanılan girdi miktarı dikkate alındığında sadece makine işgücü isteği değerinin işletme büyüklük grupları arasında %5 düzeyinde istatistiki yönden farklılık gösterdiği anlaşılmıştır. Araştırma bulguları incelenen işletmelerde girdi kullanımı açısından, işletme grupları arasında istatistiki yönden önemli bir fark bulunmadığını, bu durumun da kanola üretim teknolojisindeki benzerlik yanında büyük işletmelerin ölçek ekonomisinin pozitif yönlerinden faydalanamadığını göstermektedir. Bu nedenle orta ve uzun vadede genelde tarımsal üretimde özelde ise kanola üretiminde işletmelerin üretim düzeyleri dikkate alınarak farklı araçlarla ve değişik yöntemlerle desteklenmesi gerektiğini ortaya koymaktadır.
