(Medwell online, 2008) Karakus, Kadir; Budag, Cemal; Tuncer, S. Seckin; Ozdemir, Taner; Eyduran, Ecevit
The present study was conducted to determine the effects of several environmental factors on 572 lambs (229 Karakas and 343 Norduz) raised at Research and Application Farm of Agricultural Faculty, Yuzuncu Yil University, Van, Turkey. In this study, birth type (single and twin), gender (male and female), dam age at lambing (1, 2, 3, 4, 5, 6 and 7) and birth year (2004, 2005, 2006 and 2007) and birth weights (kg) of Norduz and Karakas Lambs were recorded. According to results obtained from the present study, genotype factor on birth weight of Norduz lambs was non-significant, the influences of gender (p<0.001), dam age (p<0.01), birth type (p<0.001) and birth year (p<0.001) on it were found significant. As a result, the birth weight trait provides useful information for early selection criteria in breeding program.
Environmental Factors Influencing Birth Weights of Norduz and Karakas Lambs

The aim of this study was to compare birth weights of Norduz and Karakas genotypes and determine the effects of gender, birth type, dam age and genotype on birth weight. The data were composed of a total of 204 (103 Norduz and 101 Karakas) lambs born in 2003 in Van, in located region of the Eastern Anatolia, Turkey. The effects of gender (p<0.05), birth type (p<0.05) and dam age (p<0.05) on birth weight were found to be significant, whereas difference among averages of birth weight of breeds was found to be non-significant. As a result, using of birth weight as crucial criterion for early selecting animal is based on determination and elimination of some factors affecting the trait.
Utilization of Profile Analysis in Animal Science
(Medwell online, 2008) Eyduran, Ecevit; Yazgan, Kemal; Ozdemir, Taner
The aim of this study was to examine Profile Analysis by using a sample from Animal Science. Profile Analysis, a multivariate approach to Repeated Analysis is an alternative to MANOVA due to ensuring different information to a researcher such as comparison of levels of treatment, repeated measurement and treatment by time interaction. Besides, PA is an advantageous because it doesn't require spherity assumption in MANOVA. As a result, PA has been widely used in social and psychology fields except from animal science. Because of these reasons, in the future it was suggested and based on our results that PA could be used for studies regarding animal science containing repeated measurement.
