2020
Serkan Yazarel | Şenay Sarıca | Sedat Karaman
Proteins consumed by poultry turns into ammonia as a result of microbial activities depending on the pH, temperature, moisture content of the litter, litter type, manure condition, relative humidity and ventilation condition and spreads to the environment as ammonia gas. Ammonia gas, which is one of the problems caused by poultry breeding, is a harmful gas in terms of animal welfare, health of employees and its effects on the environment. In this article, ammonia gas emission in poultry and practices to reduce this emission have been discussed and recommendations have been made.

In turkey, one of the most important problem of livestock’s production is insufficiency of quality forage crop, but still few forage species are cultivated. On the other hand, conservation of plant genetic resources has become an important problem in the world today. Indeed, biodiversity is an indispensable element of human life, especially food, and it is estimated that 20% of these resources will extinct by 2030. The aim of study was to determine some quality traits of white sweet clover (Melilotus alba Desr.) collected from natural flora of Bilecik province. In this study, plants were collected at the flowering stage and investigated of 17 genotypes. The determined quality traits of genotypes as fallows; crude protein, ADF, NDF, RFV, K, P, Mg, Ca and Ca/P, and these traits were noted as11.99-21.07%, 27.70-40.53%, 43.31-55.84%, 93.44-147.02, 1.300-2.807%, 0.187-0.310%, 0.127-0.350%, 0.490-1.417% and 2.05-5.92%, respectively. As a result of the study, it has been determined that the quality of the white sweet clover genotypes collected from Bilecik natural flora have been sufficient for animal feeding and have a significant potential for future breeding activities.

Biology of the Lonicera whitefly, Aleyrodes lonicerae Walker (Hemiptera: Aleyrodidae) were studied on rose, Rosa sp. (Rosaceae) plants. Whitefly adults were collected from Mercurialis annua L. (Euphorbiaceae) plants in Adana. The development duration of egg, first, second, third, fourth larval (pupa) stages, total of A. lonicerae on Rosa sp. plants at 20°C were 8.44, 5.44, 5.50, 4.50, 5.19 and 29.07 days for the females and 8.15, 5.46, 5.92, 4.92, 5.38, 29.83 days for the males respectively. The development duration of egg, first, second, third, fourth larval (pupa) stages, total of A. lonicerae on Rosa sp. plants at 25°C were 8.00, 1.67, 2.33, 2.67, 9.67, 24.34 days for the females and 7.67, 2.33, 2.33, 3.33, 7.83 and 23.49 days for the males respectively. The mortality rate (%) of egg, first, second, third, fourth larval (pupae) stages of A. lonicerae at 20 and 25°C temperatures were 14.70, 13.97, 25.00, 20.58, 4.41; 2.89, 24.65, 26.08, 20.28, 13.06 respectively. The biggest k values at 20 and 25°C on rose plants were 0.2553 for the third larval stage and 0.3010 for the fourth larval stage, respectively.

It is very important to develop a new way of treatment for foodstuffs to provide consumers more chances to choose their foods. In the present study, we aimed to investigate the effect of microwave drying conditions on the rehydration process of Algerian truffles. Previously dried truffles, at different microwave power output (350, 500 and 650 Watt) and weights (100 and 150 g) have been utilized to analyses and to model the rehydration kinetics. Among the six used empirical models, Weibull model has been the most fitted model to all the treated samples. Microwave power output and sample weight were found to have an effect on truffles during drying, and consequently on their rehydration capacity. The high samples amount has decreased the effects of microwave drying by decreasing the density of treatment, also, the high-power output has probably reduced the time of evaporation, and thus more preservation to the dried truffles. These results can be taken into consideration for more industrial applications of microwave drying and subsequent rehydration of truffles.

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.

Araştırma, Çukurova Üniversitesi Ziraat Fakültesi Araştırma ve Uygulama Çiftliğinde bulunan Rio Red altıntop ağaçları kullanılarak 2011 ve 2012 yıllarında yürütülmüştür. Çalışmada, deneme bahçesindeki mevcut sulama proğramının değerlendirilmesi ile ağaçlara farklı düzeylerde uygulanan sulama suyu miktarının, verim ile meyve kalite özellikleri (pomoloji) üzerine etkilerinin belirlenmesi amaçlanmıştır. Denemede damla sulama sistemi ile 3 farklı miktarda sulama suyu uygulanmıştır (I100); (I70); (I50). Her iki yıl dikkate alındığında sulama suyu miktarları, 332,48 mm (I100) ile 128,69 mm (I50) arasında değişmiştir. Gerçek bitki su tüketimleri ise su bütçesi yöntemine göre 935,6 mm (I100) ile 729,9 mm (I50) arasında gerçekleşmiştir. Denemenin birinci yılında, sulama konularına ilişkin verimler, ağaç başına, 306 (I70) ile 330 (I50) kg, ikinci yıl ise ağaç başına ortalama verim değerlerinin sulama konularına göre, 59,6 kg (I100) ile 108,5 kg (I50) arasında değişmiştir. Toplam su kullanma randımanları, 2011 yılında, WUEET 5,18 kg m-3ile 6,34 kg m-3, 2012 yılında ise; 0,52 kg m-3ile 1,74 kg m-3arasında elde edilmiştir. Sulama suyu kullanma randımanları, 2011 yılında, WUEI 15,85 kg m-3ile 30,69 kg m-3, 2012 yılında ise; 2,17 kg m-3ile 14,27 kg m-3değerleriarasında değişmiştir. Denemenin birinci yılında ortalama suda çözünen kuru madde miktarları, %10,22 (I100) ile %12,91 (I50) arasında; ikinci yılında ise %12,41 (I100) ile %13,47 (I50) arasında değişmiştir. Bu çalışma kapsamında sulama konularının meyve verimine etkilerinin istatistiksel olarak önemli olmamasından dolayı çifçilere su tasarrufu sağlamak amacıyla yöre için su kısıntısı önerilebilir.
