Lactation curve and persistency of Anatolian buffaloes

WOS: 000360812300003The aim of this study was to determine the lactation curve traits of Anatolian buffaloes raised under different conditions in farms in Tokat Province, Turkey. Wood's gamma curve parameters were employed to identify the lactation curve types, and values for the parameters beginning yield (a), coefficient of rising (b) and coefficient of decreasing (c) were used to determine the shape and type of lactation curve. All parameters in typical lactation curves were positive, and in the event of one parameter being negative, the curve was considered to be an atypical lactation curve. A total of 690 lactation curves were investigated. It was determined that 406 (58.84%) of these curves were typical, while 90 (13.04%) were concave and 194 (28.12%) of a decreasing type. For typical lactation curves, a, b, c, persistency (S), time after parturition until the peak yield occurs (T-max), maximum daily peak yield (Y-max), and coefficient of determination (R-2) were 7.14 +/- 0.008, 0.85 +/- 2.1, 0.40 +/- 0.001, 2.68, 63.6, 6.41 and 76.33, respectively. For concave lactation curves, values for a, b, c, T-max, Y-max and R-2 were 4.94 +/- 0.42, -0.73 +/- 0.016, -0.23 +/- 0.0038, 95.40, 7.41 +/- 0.004 and 71.68, respectively. For decreasing typical lactation curves, values for a, b, c, T-max, and R-2 were 5.31 +/- 0.0041, -0.15 +/- 0.007, 0.039 +/- 0.0023, 3.89 +/- 0.11 and 79.94, respectively. Parameters predicted by the Wood model within the scope of this study have the potential of being useful for breeding programmes. Further breeding/selection activities could be conducted by using the female Anatolian buffaloes with typical lactation curves

Size induced metal insulator transition in nanostructured Niobium thin films: Intragranular and intergranular contributions

With a reduction in the average grain size in nanostructured films of elemental Nb, we observe a systematic crossover from metallic to weakly-insulating behavior. An analysis of the temperature dependence of the resistivity in the insulating phase clearly indicates the existence of two distinct activation energies corresponding to inter-granular and intra-granular mechanisms of transport. While the high temperature behavior is dominated by grain boundary scattering of the conduction electrons, the effect of discretization of energy levels due to quantum confinement shows up at low temperatures. We show that the energy barrier at the grain boundary is proportional to the width of the largely disordered inter-granular region, which increases with a decrease in the grain size. For a metal-insulator transition to occur in nano-Nb due to the opening up of an energy gap at the grain boundary, the critical grain size is ~ 8nm and the corresponding grain boundary width is ~ 1.1nm

Splenic infarction as a complication of celiac artery thromboembolism: an unusual cause of abdominal pain

Splenic infarction is a relatively uncommon diagnosis and this clinical presentation can mimic other causes of acute abdominal pain. Cardiologic and hematologic disorders are common reasons for this entity. There have been a few series and single case reports of splenic infarction published in peer-reviewed medical journals. We report a 53-year-old patient who had splenic infarction caused by celiac artery thromboembolism. The importance of this case, without any etiological predisposing factors, is that this kind of clinical situation should be considered in the differential diagnosis of abdominal pain

Comparison of Different Lactation Curve Models of Anatolian Buffaloes

WOS: 000344690200005In this study, eight different lactation curve models were compared by using test day milk yield records belonging Anatolian Buffaloes raised in different Farm conditions between 2011 and 2013. To identify the best lactation curve models of Wood, Cobby and Le Du, Logaritmic Quadratic, Exponential, Parabolic exponential, Quadratic, Inverse Polynomial and Logaritmic Linear mathematical functions were used. The coefficient of determination (R-2) and residual standard deviation (RSD) statistics were used for determination of best fitted model in lactation curve. Logaritmic Quadratic and Quadratic functions are the best goodness of fit model as having the highest R-2 and lowest RSD coefficients. As a result, the parameters are estimated by logarithmic quadratic or quadratic models, for use in breeding programs will make an important contribution to research in this field

THE EFFECT OF DRY CAPER (Capparis spinosa) FRUIT ON EGG PRODUCTION AND QUALITY CHARACTERISTICS OF LAYING HENS

WOS: 000334022300028This study was conducted to determine the effect of increasing dietary inclusion of dry Caper (Capparis spinosa) fruit (DCF) on egg production and quality characteristics of laying hens between 20 and 32 weeks of age. Four groups of commercial hens (ATAK-S) were fed with diets containing 0, 5, 10 and 15 g DCF/kg. The results showed that final body weight, feed intake, shape index (SI) and morning hen-day egg yield were influenced by dietary supplementation of DCF (P0.05) during the entire experiment. The lightness (L*) and redness (a*) values for egg shell color were similar (P>0.05) in the DCL supplemented groups as compared to the control group. The yellowness (b*), Hue angle (H), chroma (C*) and Delta E* values were lower (P<0.05) in 15 g DFC/kg group when compared with the control. Trolox equivalent antioxidant capacity (TEAC), ferric reducing antioxidant power (FRAP) and total phenolics amount of DCF were 43.75 +/- 0.680 mmol trolox/kg, 60.03 +/- 3.710 mmol TEAC/kg and 3.16 +/- 0.060 g gallic acid equivalents (GAE)/kg, respectively. Based on the results from the current study, the dietary supplementation with dry DCF had adverse effects on productivity performance traits and egg quality
