This study was carried out to investigate the possibilities of making silage from fruit juice industry waste.For this purpose, orange, lemon and tangerine pulp silage quality have been determined by comparing silage with maize and beet pulp silage.Treatment groups; 1) orange, 2) tangerine, 3) lemon, 4) maize and 5) sugar beet pulp. The silages were evaluated after 2 months from ensiling in the following areas: subjective evaluation, pH, dry matter, organic matter, crude protein, acid detergent fiber, neutral detergent fiber, ether extract and energy values (metabolizable energy) and net energy for lactation were calculated. As a result, it was determined that fruit juice industry residues were lower in terms of dry matter, but they contained higher energy due to their high organic matter content, digestibility and low cellulose content. In addition, it was determined that citrus pulp was evaluated as silage without any contribution.

Bu çalışmanın amacı, Karayaka koyunlarında dönem içi gonadotropin salgılatıcı hormon (GnRH) uygulamasının kızgınlık gösterme oranı ve ovaryum aktivitesi üzerine etkisini belirlemektir. Çalışmada en az iki doğum yapmış ve benzer vücut ağırlığına sahip 20 baş Karayaka ırkı koyun hayvan materyali olarak kullanılmıştır. Deneme başında tüm koyunlara ovaryum üzerinde mevcut olabilecek olan korpus luteum (CL)’un yıkımı için 1 ml PGF2α kas içi enjekte edilmiştir. PGF2α uygulamasından 9 gün sonra ise koyunlar rastgele iki eşit gruba ayrılmıştır. Birinci gruptaki koyunlara (n=10) 40 mg flugestone asetat içeren sünger vajina içine yerleştirilmiştir ve bu uygulamadan 14 gün sonra süngerler çıkartılarak, 1 ml PGF2α kas içi enjekte edilmiştir. PGF2α enjeksiyonunu takiben 36 saat sonra 1 ml GnRH kas içi enjekte edilmiştir. İkinci gruptaki koyunlara (n=10) ise mevcut olabilecek olan korpus luteum (CL)’un yıkımı için 1 ml PGF2α kas içi enjeksiyonun dışında herhangi bir uygulama yapılmamış olup, bu grup çalışmamızın kontrol grubunu oluşturmuştur. Bu işlemleri takiben her iki gruptaki bütün koyunlar Karayaka koçuna verilmiş ve 72 saat boyunca kızgınlık gösteren koyunlar belirlenmiştir. Kızgınlık taramasının sonunda bütün koyunlar kesime sevk edilmiş ve her iki ovaryum üzerindeki küçük (1-3 mm), büyük (>3 mm) ve toplam folikül sayısı ve CL sayısı belirlenmiştir. GnRH uygulaması yapılan koyunlar (%100) kontrol grubundaki koyunlara (%70) göre daha yüksek oranda kızgınlık göstermişlerdir. GnRH uygulaması yapılan koyunların her iki ovaryumundaki küçük ve toplam folikül sayısının ve CL sayısının, kontrol grubundaki koyunlarınkinden daha yüksek olduğu tespit edilmiştir. Ancak büyük folikül sayısı bakımından deneme grupları arasında bir farklılık tespit edilmemiştir. Sonuç olarak bu çalışmada mevsim içi dönemde Karayaka koyunlarında sünger uygulaması sonrasındaki GnRH uygulamasının kızgınlık gösterme oranını yükselttiği ve ovaryum aktivitesini arttırdığı tespit edilmiştir.

This research was conducted during 2016-2017 awheat growing season to investigate the effects of different rates of seed coating of an organic acid mixture (citric acid, glutamate, and proline) on yield and quality of wheat. The field experiments were established in Dogankent and Haciali locations of Eastern Mediterranean Agricultural Research Institute in Turkey. Study was carried out with randomised complete block design with 4 replications and Ceyhan-99 bread wheat variety was used as seed material. Before seeding, wheat seeds were coated with organic acid mixture product (0.75% citric acid, 0.25% glutamate, 0.25% proline, 2% Zn and 96.75 water), in three different doses (500 ml ton-1, 1 l ton-1, 1.5 l ton-1) to compare with control (uncoated). There were statistically significant differences at 5% level in 1000 grain weight and grain yield values in Dogankent location and 1000 grain weight, grain yield and number of spikes in Hacialilocation. Highest yield values were obtained from 500 ml t-1 application dose for both locations. With 500 ml t-1 application dose at Dogankent location, grain yield was 11.9 t ha-1 which was 8.97% higher over control. In Hacali location, 500 ml t-1 application dose was increased yield by 15.96% compared to control which resulted with 10.5 t ha-1 grain yield. No statistically significant difference was observed in quality characteristics (protein, gluten, hardiness and sedimentation) in trials.

This study was carried out in Rize province in 2016, on fresh leaf samples collected from an organic tea plantation. In this study, the aim was to determine the effect of pruning age (1st year, 3rd year and 5th year following the last pruning) and diurnal variability on antioxidant activity and dry matter rate in tea leaves depending on shoot periods. When the pruning age was considered, the highest antioxidant activity was obtained from the plants which were in 5th pruning age in the 1st shoot period with 4991,1 μmol FeSO4/g dw. In terms of the same trait, the effect of pruning age on antioxidant activity during the 2nd shoot period was insignificant, while the highest antioxidant activity in the third shoot period was obtained from 1st pruning age with 7229.2 μmol FeSO4/g dw. As a general average, considering intraday collecting time, antioxidant activity in leaves collected in morning (07.00) and at noon (12.00) was very close to each other, while the collected leaves in the evening (17.00) had higher values. The dry matter rates obtained from the 1st, 3rd and 5th pruning ages were 23.45%, 25.23% and 25.45% respectively. When the shoot period was considered, the lowest dry matter rate was 20.17% in the first shoot period and the highest dry matter rate was 28.8% in the 2nd shoot period and high values were obtained from the leaves collected at noon.

Bu çalışmada dünyada ve Türkiye’de önemli bir gıda ve endüstriyel hammadde kaynağı olan mısırın ekonomik gelişim seyrinin incelenmesi amaçlanmıştır. Bu amaç doğrultusunda ikincil verilerden derlenen mısırın yetiştirildiği alanı, üretim miktarı, verimliliği, üretim- tüketim dengesi, ithalat-ihracat değerleri, yurtiçi ve yurtdışı fiyatları incelenmiştir. Dünyadaki başlıca mısır üreten ülkeler ile Türkiye’de mısırın gelişim seyri iç ve dış piyasa açısından değerlendirilmiştir. Dünyada olduğu gibi Türkiye’de de yıllar itibariyle mısırın verimliliği ve üretim alanları artmış, buna bağlı olarak da hem üretim miktarı hem tüketim miktarında artış olduğu görülmüştür. Amerika Birleşik Devletleri (ABD) mısır üretimi ve tüketiminde ilk sırada yer alırken, mısır en çok hayvansal üretimde yem olarak kullanmıştır. İthalat ve ihracat değerleri incelendiğinde ABD iç tüketimini karşılama açısından başarı göstermiş ve iç tüketimini karşılamanın yanı sıra mısırın ihracatında da önemli rol almıştır. Türkiye’de ise 2016/17 üretim yılı içerisinde mısırın yeterlilik derecesi %87,80 olarak belirlenmiş ve yıllar itibariyle yeterlilik oranının arttığı belirlenmiştir. Dünyadaki nüfus artışına bağlı olarak gıda talebinde oluşacak artışlar, alternatif enerji kaynağı arayışları ve mısırın kullanım alanının genişlemesine bağlı olarak gelecek yıllarda mısıra olan talebin artmaya devam etmesi ve dolayısıyla yaratılan ekonomik değerinde artması beklenmektedir.

Sustainability and development of the dairy enterprises are dependent on competitiveness. Determination of the performance of the enterprises requires measurement and analyses of the financial performance of the enterprises. The ability of dairy enterprises to continue and grow is dependent on competitiveness. It requires that the financial performance of the farm enterprises be measured and analysed in order for the enterprises to be able to detect the competition power in a healthy manner. The aim of the study is to analyse the financial performance of the dairy enterprises in Konya province by determining the capital structure. Çumra, Karapınar and Ereğli districts constituted 15% of the number of bovine animals, were selected by using sampling method. The number of dairy cattle in these enterprises constituted the main frame of the population the primary data collected from 125 dairy farm enterprises with questionnaire technique through stratified sampling method with 95% confidence interval and error margin of 5%. The capital structure of the enterprises surveyed in the research area was classified according to their functions and the average active capital of the enterprises was calculated as 845,330.85$. 67.87% of the active capital is composed of land capital, 31.70% is composed of fixed enterprises capital and 0.43% is variable working capital. The economic profitability level (EP) was determined as 6.90% and the financial profitability level (FP) indicated the success of the enterprise was calculated as 7.06%. The capital turnover rate, an important indicator in the success and comparison of the enterprises, is 28.22%. As a result, their development and competitiveness are slow, because they do not use enough business and investment capital.

One-year investigation is carried out aimed at evaluating all incomes and costs with a specific focus on the impact of feeding factors in 12 Holstein dairy farms (in total 284 cows) in Kosovo. The cost of on-farm produced feeds; the price of purchased feeds and the price of milk were used for the analysis. All costs created during this period are duly registered and considered in the analysis. Economic analysis showed that prices of on-farm produced feed were much lower (30 €/ton for silages and for hay). Average daily feed cost was 2.33 €/cow/day, while milk income was only 4.9 €/d. Individual feed groups contributed to total milk cost as follows: silages with 0.04 €/kg, dry roughages with 0.02 €/kg, and concentrates with 0.10 €/kg, while all other factors taken 0.13 €/kg of milk price. This study showed that feed was the largest farm expense making 68% of total farm costs.

Bu çalışmada yeme antibiyotik (amoksisilin+klavulanik asit) ve probiyotik ilavesinin gökkuşağı alabalıklarında (Oncorhynchus mykiss) bazı immünolojik ve serum biyokimyasal sağlık karakteristikleri üzerine etkilerinin araştırılması amaçlanmıştır. Yeme ilave edilen antibiyotik veya probiyotik katkılarının lizozim aktivitesi, myeloperoksidaz aktivitesi, serum total protein, albümin, globülin, trigliserit ve kolesterol değerleri üzerine herhangi bir etkisinin olmadığı belirlenmiştir. Antibiyotik ile beslenen balıkların serum glikoz düzeyleri kontrole göre önemli oranda artmıştır. Bununla birlikte antibiyotik ile beslenen balıkların GOT değeri kontrole göre önemli oranda azalmıştır. Ayrıca LDH ve ALP değerleri antibiyotik ve probiyotik ilavesi ile kontrole göre azaldığı belirlenmiştir. Bu çalışma, tek bir deneysel model olup farklı balık türlerinde ve farklı balık patojenlerinde karşı probiyotik kullanımı farklı dozlara veya zamana bağlı olarak değişebilir. Bu nedenle bu çalışma çeşitli kan parametrelerinin değerlendirilmesi açısından diğer çalışmalara ışık tutmaktadır.
