The application of six different models to estimate the genetic parameters, variance components and breeding values for birth weight of Holstein calves
Sahin, Aziz; Ulutas, Zafer; Ugurlutepe, Emre (TAYLOR & FRANCIS LTD, 2017)This research was conducted to determine variance component, genetic parameters and breeding values (EBV) for the birth weight (BW) of Holstein calves. In this context, the direct genetic (sigma(2)(a)), maternal genetic ... -
Comparison of Different Lactation Curve Models of Anatolian Buffaloes
Sahin, Aziz; Ulutas, Zafer; Yildirim, Arda; Aksoy, Yuksel; Genc, Serdar (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2014)In 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 ... -
Comparison of Growth Curve Using Some Nonlinear Models in Anatolian Buffaloe Calves
Sahin, Aziz; Ulutas, Zafer; Karadavut, Ufuk; Yildirim, Arda; Arslan, Servet (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2014)The aim of the research was to detect the best model to explain the variation of live weight of Anatolian buffaloes using the nonlinear models. For this purpose, in the production period of 2011- 2012, live weight records ... -
