Facts About Footrot - A Special Booklet For Neighbours Of Properties Which Have Been Quarantine For Footrot, Or Farmers Wanting To Know More About Footrot, Department Of Agriculture, Western Australia

Animal production and livestock published reports

Footrot is a contagious disease of sheep and goats caused by a mix of different bacteria, with the essential one being Dichelobacter nodosus. The bacterial infection can cause varying degrees of damage to the horn of the foot, leading to lameness, and significant loss of body weight and wool production.

There are two main forms of footrot - virulent and benign. Both are caused by D. nodosus. Footrot is diagnosed using two methods; inspecting sheep's feet, and testing skin scrapings in the laboratory

Destructive Effects Of Classical Viscosimeters On The Microstructure Of Yoghurt Gel, Barbaros H. Özer

Turkish Journal of Agriculture and Forestry

The effects of empirical viscosity measuring techniques that are commonly used in the determination of the viscosity of weak viscoelastic gels such as yoghurt on the microstructure of yoghurt were investigated by scanning electron microscopy (SEM). In the measurement of viscosity, Brookfield and Haake viscosimeters were employed at 2 different measuring periods (15 and 30 s). The results obtained indicated that the increase in the measuring period (15 s versus 30 s) stimulated the further destruction of the casein gel network. Additionally, the Brookfield viscosimeter was more destructive than the Haake viscosimeter. In general, lower viscosity values were in good …

The Effects Of Urban Green Spaces On House Prices In The Upper Northwest Urban Development Area Of Adana (Turkey), M. Faruk Altunkasa, Cengi̇z Uslu

Turkish Journal of Agriculture and Forestry

Green spaces have very important functions in the creation of a sustainable city. However, in cities, which grow in terms of their population and physical environment, the primary aim of city planning is to meet the housing deficit. For this reason, areas having natural characteristics within an urban area are destroyed and existing green spaces are turned into housing areas. The most important reason why green spaces are not prioritized in city planning is that there is no market representing the green spaces. The market value of green spaces is hard to quantify. The higher price paid by customers for …

Modeling Approaches To Salt Management Problems In Irrigated Agriculture: A Review, Ataç Tuli̇, William Austin Jury

Turkish Journal of Agriculture and Forestry

Irrigation projects have been developed throughout human history to increase food production, but they frequently contribute to salinization and drainage problems as well. Examples where salinization and drainage water disposal due to agricultural activity are a critical problem can be found in irrigated areas in different parts of the world. To find possible solutions to irrigation and drainage related problems, government agencies, scientists, and soil and water resources managers recommend a broad array of management alternatives for conducting investigations. The concept of management alternatives of salinization and drainage problems can be evaluated by field experiments and/or by simulating conditions with …

Hormone Signaling Pathways In Plants: The Role Of Jasmonic Acid In Plant Cell Signaling, İskender Ti̇ryaki̇

Turkish Journal of Agriculture and Forestry

Plant growth and metabolism are affected by various biotic and abiotic stimuli including microorganisms and insects attack as well as light and environmental stresses. Such a diverse plant response requires a communication system that uses a group of chemical messengers called hormones. Hormones promote, inhibit, or qualitatively modify plant growth and development. This complex process requires a signal transduction that defines a specific information pathway within a cell that translates an intra- or extracellular signal into a specific cellular response. The characterization of mutants in the hormone response pathway provides not only an excellent opportunity to understand hormone action in …

Insect Growth Regulators For Insect Pest Control*, Hasan Tunaz, Nedi̇m Uygun

Turkish Journal of Agriculture and Forestry

Insecticides with growth regulating properties (IGR) may adversely affect insects by regulating or inhibiting specific biochemical pathways or processes essential for insect growth and development. Some insects exposed to such compounds may die due to abnormal regulation of hormone-mediated cell or organ development. Other insects may die either from a prolonged exposure at the developmental stage to other mortality factors (susceptibility to natural enemies, environmental conditions etc) or from an abnormal termination of a developmental stage itself. Insect growth regulators may come from a blend of synthetic chemicals or from other natural sources, such as plants. The chemical composition of …
