Effects of ventilation of the sheep house on heat stress, growth and thyroid hormones of lambs

PubMedID: 21365357Twenty single male Assaf lambs were divided into two groups and housed in semi-open barns. Air temperature averaged 35°C. For 9 weeks after parturation, one group was cooled by fan between 1000 and 1600 hours and the other group was not cooled. Rectal and skin (head and testis) temperatures, respiration rate, and pulse rate were recorded twice daily. Lambs were weighed individually every week and levels of T3 and thyroxin were determined. Differences in rectal, head, and testis temperatures (P < 0.05) and respiration rates (P < 0.01) between the two groups were significant. Growth was affected positively by fan treatment, live weight increased by 15%, and cooled lambs had higher thyroxin levels. © 2011 Springer Science+Business Media B.V.Acknowledgments This study was supported by ZF2009/BAP-22 Project of Cukurova University.

A case study for production system analysis of turkish angora goat farms

The aim of this study was to determine both the current economic situation and the major characteristics of Angora goat farms. For this study, 100 goat farms were surveyed in the Ankara province, specifically, the Polatli, Gudul, Ayas, Beypazari, and Nallihan district, to examine the role breeding plays in the rural economy. In addition to technical analyses of Angora goat production, some outstanding traits of Angora goats were determined. There were no significant differences among the Polatli, Nallihan, Ayas and Gudul provinces, except for the Beypazari province in terms of goat population (P < 0.05). Over the last twenty years, the number of angora goats has decreased by almost 89%. Total mohair, milk and meat production has slumped because of the decrease in goat numbers. The main income of these farms is obtained from mohair, meat and the sale of live animals. Most of the milk produced from the goats is consumed by the families of the farmers. Concentrated feed is used by the majority of farms when the goats are housed in pens, especially in wintertime. Among farmers, 91% declared the use of concentrated feed throughout the entire year, whereas 9% of them use it only in wintertime

Vortex Identification in Turbulent Flows Past Plates using Lagrangian Method

Vortex identifications in turbulent flows past arrays of tandem plates are performed by employing the velocity field obtained by high fidelity large eddy simulations (LES). Lagrangian coherent structures (LCSs) are extracted to examine the evolution and the nonlinear interaction of vortices and to characterize the spatial and temporal characteristics of the flow. LCSs identification method is based on the Finite-Time Lyapunov Exponent (FTLE) which is evaluated using the instantaneous velocity data. The simulations are performed in three-dimensional geometries to understand the physics of fluid motion and the vortex dynamics in the vicinity of plates and surfaces at Reynolds number of 50,000. The instantaneous vorticity fields, Eulerian Q-criterion and LCSs are presented to interpret and understand complex turbulent flow structures. The three-dimensional FTLE fields provide valuable information about the vortex generation, spatial location, evolution, shedding, decaying and dissipation of vortices. It is demonstrated here that FTLE can be used together with Eulerian vortex identifiers to characterize the turbulent flow field effectively.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Comparison of real-world clinical and economic outcomes between the ThermoCool&reg; SF and ThermoCool&reg; catheters in patients undergoing radiofrequency catheter ablation for atrial fibrillation

Larry Chinitz,1 Laura J Goldstein,2 Andrea Barnow,2 Sonia Maccioni,2 Mehmet Daskiran,3 Iftekhar Kalsekar,4 Rahul Khanna4 1NYU Langone Health, New York, NY, USA; 2Johnson &amp; Johnson Medical Devices, Irvine, CA, USA; 3Janssen, Raritan, NJ, USA; 4Johnson &amp; Johnson Medical Device Epidemiology, New Brunswick, NJ, USA Introduction: This study evaluated the real-world clinical and economic outcomes associated with the use of the ThermoCool&reg; Surround Flow (SF) and ThermoCool&reg; catheters in atrial fibrillation (AF) ablation.Methods: Adults with AF who underwent catheter ablation between January 1, 2013, and December 31, 2016, in a hospital outpatient setting were identified from the Premier Healthcare Database. Using a search strategy of hospital-charge descriptors, patients were classified into two mutually exclusive groups: ThermoCool&reg; SF catheter and ThermoCool&reg; catheter. A generalized estimating equation was used to compare index admission cost. Survey logistic regression was used to compare the incidence of inpatient readmission, direct-current cardioversion (DCCV), and repeat ablation. Multivariable analyses were adjusted for hospital clustering and demographic, procedural, hospital, and comorbidity characteristics.Results: There were 1,014 and 463 patients in the ThermoCool&reg; SF and ThermoCool&reg; groups, respectively. The ThermoCool&reg; SF group had significantly lower odds of all-cause (odds ratio [OR] 0.45; 95% CI 0.27&ndash;0.76) and cardiovascular-related readmissions (OR 0.45; 95% CI 0.21&ndash;0.96), and DCCV (OR 0.61; 95% CI 0.42&ndash;0.88) than the ThermoCool&reg; group. In patients susceptible to fluid overload, the ThermoCool&reg; SF group had significantly lower odds of 12-month all-cause (OR 0.42; 95% CI 0.23&ndash;0.75), cardiovascular-related (OR 0.31; 95% CI 0.10&ndash;0.92), and AF-related readmissions (OR 0.18; 95% CI 0.04&ndash;0.80), and DCCV (OR 0.52; 95% CI 0.31&ndash;0.87) than the ThermoCool&reg; group.Conclusions: Using the ThermoCool&reg; SF catheter for AF ablation was significantly associated with improved clinical outcomes compared with the ThermoCool&reg; catheter. Keywords: atrial fibrillation, radiofrequency ablation, irrigated-tip catheter, ThermoCool&reg; Surround Flow catheter, ThermoCool&reg; cathete

IMMUNIZING NORDUZ GOATS AGAINST INHIBIN**

Abstract: The objective of this study was to investigate the effect of active inhibin immunization on follicular development and prolificacy in Norduz goats. Two times inhibin α- subunit 1-32 porcine was used for preparation of vaccine. It was observed that goats were successfully immunized against inhibin, following ultrasonographic inspection and antibody binding test. High number of follicles were developed in immunized goats. But, active immunization does not improve prolificacy in Norduz goats

Goat production systems of Turkey: Nomadic to industrial

Goats play an important socio-economic role in many marginal rural areas of the world. Indigenous goat breeds have taken an important role in the livelihood strategies of impoverished farmers, especially those in harsh, remote areas. Those roles include their use as security and diversification of assets, social and cultural functions. They are also valued for their productive performance, adaptation and disease resistance. Turkey is one of the leading countries in the world for goat population and production. Hair, Kilis, Angora and Shami are the main goat breeds of the country. Hair goats are raised in many parts of the country but are concentrated particularly in the mountainous regions country, while the Angora breed is concentrated mainly in Central Anatolia. Kilis and Shami goats are known for their higher milk yield and litter size and are mainly focused in the south-east region of Turkey. Apart from these four breeds, the minor breeds such as Honamlı are located in the Bolkar Mountains in the Mediterranean region (specifically Antalya, Isparta and Konya) and the Norduz breed in Van province. A limited number of dairy goats such as Maltız, Saanen and their crossbreds are located in the Aegean and Marmara regions of Turkey. The population of goats in Turkey is about 11 million head. Hair goats make up approximately 10 million of the total number and the rest make up the balance. There are many reasons for goat production in Turkey, including the country's geography and ecological condition, as well as the socio-economic situation of the rural communities. Goats have been raised in the Anatolian Plateau for many centuries providing dairy, meat, hide and hair to the inhabitants. It is the main source of animal protein for the rural masses in the mountainous regions of the country and less so for the urban population. Goats provide approximately 3% of the total red meat, 2.5% of the total milk and 18.5% of the total hide production for Turkey. They are also the only source of mohair and animal hair production in the country. Although their number and economic significance has decreased over the years, goat breeding still plays and important socio-economic role for the people living in remote areas of Turkey. Investments in intensive goat enterprises have increased significantly in the last few decades in Turkey although marketing margins across the value chain between producers, middlemen, processors, and consumers unjustifiably irregular. © 2017 Elsevier B.V
