2017
Çağrı Çağlar Sinmez | Aşkın Yaşar
Organik hayvansal üretim, hayvanların fizyolojik ihtiyaçlarına uygun bakım ve besleme yöntemlerinin uygulandığı, gerektiğinde alternatif ilaç ve tedaviye öncelik verilerek hayvan sağlığının korunduğu doğal bir yetiştirme sistemidir. Hayvan yetiştiriciliğinde kullanılan antibiyotik ve antiparaziter ilaçlara karşı dirençli suşların giderek artması, hayvansal ürünlerde ilaç kalıntılarının meydana gelmesi ve bu ürünleri tüketen insanlarda önemli sağlık problemlerine yol açması alternatif bitkisel çözüm arayışlarını beraberinde getirmiştir. Bu çalışmada, Orta Anadolu Bölgesi halk veteriner hekimliği özelinde kullanılan bitkisel drogların organik hayvansal üretimde tedavi ve koruyucu etkilerinin değerlendirilmesi amaçlandı. Çalışmanın materyalini, Orta Anadolu Bölgesi’ndeki (Çankırı, Kayseri, Kırıkkale, Kırşehir, Yozgat) hayvan yetiştiricilerinden elde edilen yazılı, sözlü ve görsel veriler oluşturdu. Çalışmada, sığır, koyun, at, tavuk, arı ve köpek türlerinde görülen iç hastalıkları, cerrahi hastalıklar, doğum ve jinekolojik sorunlar ve paraziter hastalıklarda tedavi amacıyla 30 bitkisel drogun kullanıldığı tespit edildi. Organik hayvancılıkta başta antibiyotikler olmak üzere her türlü sentetik ilaç kullanımının yasaklandığı ya da sınırlandığı değerlendirildiğinde, sürü sağlığının korunması ve tedavisinde bu maddelerin yerine doğal olan bitkisel drogların tercih edilmesinin olumlu katkılar sağlayacağı ileri sürülebilir.

Ercan Soydan | Uğur Şen | Emre Şirin
Selection of dairy cattle for higher milk yield, without considering important non-production traits, has decreased reproductive efficiency. Thus, low reproductive performance is a major problem in high yielding dairy cattle. Previous studies showed that dietary manipulation to improve fertility holds much promise and dietary fats have positive effects on reproductive functions in high yielding dairy cattle. Positive effects of fats on reproductive performance due to the fatty acids, which are the precursors of progesterone and prostaglandins. Progesterone and prostaglandins hormones are most important factors that play a role on the control of reproductive functions. The amount of linoleic, linolenic and arachidonic fattty acids in ration can be increase or decrease progesterone and prostaglandins synthesis especially PGF2α from ovary and uterus, respectively. Also fatty acids can be influence follicular development, ovulation, embryonic implantation and maternal recognition of pregnancy. This review focuses on the relationships between dietary fatty acids and reproductive functions such as hormone profiles, ovarian function and follicular development, oocyte quality, embryo development, embryonic implantation and maternal recognition of pregnancy in dairy cattle.

Oğuzhan Yanar | Elif Fatma Topkara
Plants have developed mechanical and chemical defense strategies that are effective against herbivores. Plants contain chemicals that are known as secondary metabolites (allelochemical) and these chemicals do not directly involve in organisms’ reproduction and growth, on the other hand, they affect survival, growth and behavior of species. These compounds usually take ecological tasks and plants use these compounds against diseases, parasites, and predators for interspecies competition. It is known through the observations on feeding of herbivorous insects that these compounds act as deterrent chemicals or they are toxic against them. Feeding is one of the most fundamental and the most important behaviors for herbivorous insects. Even though host plant preference of herbivores is partially depend on nutrients, this behavior greatly depends on secondary chemistry of plants. Effects of secondary compounds on herbivorous insects can be positive or negative.

The purpose of this study is to investigate the environmental factors on the milking time milk yield of Red Holstein cows. For this aim, 172,826 morning milk yield (MMY) and 172,771 evening milk yield (EMY) data collected between 2001 and 2010 from a dairy farm in Aydin Province, Turkey were used. The THI is over 72 from June to August in the region. The effects of calving month, calving year, parity, lactation month and milking month on MMY and EMY were found to be statistically significant. For every month, year and parity, the MMY means were higher than those of the EMY. The peak daily milk yield was determined on the 46th day of lactation (31.7±0.013 kg). For parity, the highest milk yield means were detected for the third parity: 13.69±0.023 kg for MMY and 11.70±0.021 kg for EMY. In conclusion, taking precautions to protect the cows from heat stress especially for the cows calved in summer and keeping the milking interval equal for whole year would help increasing the milk yield.

Wood ash generated from wood industries have enormous potential which can be utilized due to its properties which influences soil chemistry and fertility status of tropical acidic soils. Field experiments were conducted on an acidic sandy loam alfisol to investigate the effects of wood ash on the growth indices and chlorophyll content of maize and lima beans intercrop during the late and early seasons of 2014 and 2015 at Akure in the rainforest zone of southwestern Nigeria. The treatments were 100% sole maize with ash, 100% sole maize without ash, 75% maize + 25% lima beans with ash, 75% + 25% lima beans without ash, 50% maize + 50% lima beans with ash, 50% maize + 50% lima beans without ash, 25% maize + 75% lima beans with ash and 25% maize + 75% lima beans without ash. Wood ash was applied at 2.4kg/plot. Wood ash increased chlorophyll content in all amended treatments except in amended 25:75% maize-lima beans intercrop and 25:75% maize –lima beans intercrop without ash, however 75:25% maize-lima beans amended with wood ash significantly (P≥0.05) recorded the highest chlorophyll content. Growth parameters such as plant height, number of leaves, leaf area, leaf area index, leaf length, stem diameter, number of flowers, number of pods, weight of plant and total biomass of amended maize-lima beans intercrop were significantly (P≥0.05) increased by wood ash application. Based on experimental findings, 25:75% maize-lima beans intercrop and 75%:25% maize-lima beans intercrop amended with wood ash was concluded to be more recommendable in the study area.

Gelatin origin determination has been a crucial issue with respect to religion and health concerns. It is necessary to analyze the origin of gelatin with reliable methods to ensure not only consumer choices but also safety and legal requirements such as labeling. There are many analytical methods developed for detection and/or quantification of gelatin from different sources including bovine, porcine and piscine. These analytical methods can be divided into physicochemical, chromatographic, immunochemical, spectroscopic and molecular methods. Moreover, computational methods have been used in some cases consecutively to ensure sensitivity of the analytical methods. Every method has different advantages and limitations due to their own principles, applied food matrix and process conditions of material. The present review intends to give insight into novel analytical methods and perspectives that have been developed to differentiate porcine, bovine and piscine gelatins and to establish their authenticity. Almost every method can be succeeded in origin determination; however, it is a matter of sensitivity in that some researches fail to ensure sufficient differentiation.

This study was conducted to determine best evaluation method for hunted roe deer. For the research purposes, trophy papers of 192 roe deer hunted in hunting ground Srpska Crnja in 2009 and 2010 were used. A comparison of of trophy mass and CIC trophy value was carried out, as well as a comparison of mass and the trophies volume and a comparison of these two variables with an average length of the antlers and values of the aesthetic elements in order to determine whether the weight of antlers is good indicator of the value of the trophy. Where it was possible, a comparison of the commercial trophy value under the old and new system was carried out, in order to determine whether the same trophy costs the same in both systems, or which system is economically advantageous for the hunter. The results showed that the mass of trophies in most cases is a good indicator of the trophy value in CIC points. Thus, during hunting, focus should be on assessing the volume of antlers, since between volume and other indicators of the value of antlers there are stronger and more pronounced correlation than between the mass and these indicators.

Zinc (Zn) deficiency is an important mineral nutrient problem that restricts the crop yield especially that of the cereals grown in calcareous soils. This study was carried out with the aim of testing the sensitivity of various cereal species consisting of bread (BDME-10, Bezostaja), durum (Kızıltan Ç-1252) and rye (Aslım) to Zn deficiency. In experiments carried out under greenhouse conditions plants were grown at two different Zn doses (Zn 0 and Zn 5 mg kg-1). When the plants were 44 days old, Zn deficiency symptoms were observed and scored for the severity of Zn deficiency according to 1-5 scale and the plants were harvested. With respect to the severity of Zn deficiency symptoms, the most severe symptoms were observed in the C-1252 (1.0) and Bezostaja (2.0) varieties while the least mild symptoms were observed in varieties of Aslım (4.0) and Kızıltan (3.0). A distinctive increase in shoot dry matter yield has been realized with Zn application which was highest in Ç-1252 (78.8%) and BDME-10 (52.5%) varieties. Greatly differential responses have been seen to Zn deficiency among cereal species and varieties within the same species. Symptomatically and with respect to dry matter yield while durum wheat was affected severely from Zn deficiency, bread wheat was affected moderately and rye has been seen to be affected least. According to the severity of Zn deficiency symptoms and plant growth cereals which are the subject of experiment have shown a rank as as Ç1252> BDME-10> Kızıltan> Bezostaya> Aslım.
