The objective of the study was to estimate the genetic relationships between detailed reproductive traits derived from ultrasound examination of the reproductive tract and a range of performance traits in Holstein-Friesian dairy cows. The performance traits investigated included calving performance, milk production, somatic cell score (i.e., logarithm transformation of somatic cell count), carc...
________________________________________________________________________________ Abstract The objective of the study was to estimate genetic and phenotypic parameters for sow productivity traits of South African Large White pigs, using data from the Integrated Registration and Genetic Information Systems. The analyses were done on 29 719 records for 7 983 sows from 29 herds, which farrowed betw...
Purpose: The present research aims to design and test a model for evaluating the knowledge-creating ‘Ba’ (i.e. environment) in Iranian Islamic research centers based on the Triple-Helix and I-System theories and investigating the effect of personality traits, research environment and the capabilities of researchers and faculty members on the research performance of these centers. Methodology: ...
The objectives of this study were to determine whether (i) the presence and concentration of ovarian fluid (OF) affects sperm performance traits, and (ii) variation in sperm performance traits is due to male identity, female identity, and/or male×female interactions in lake trout, Salvelinus namaycush. Spermatozoa from four males were activated in river water and OF from four females at two con...
The relationships between personality traits and performance are often assumed to be linear. This assumption has been challenged conceptually and empirically, but results to date have been inconclusive. In the current study, we took a theory-driven approach in systematically addressing this issue. Results based on two different samples generally supported our expectations of the curvilinear rel...

The Old Kladruber horse is an important Czech genetic resource. In the current study, two categories of traits were evaluated – the first, a numerical score for Type and Gender Expression and the second, 11 traits describing performance divided into four categories: (1) Rideability (Overall Impression, Rideability), (2) Gaits (Walk, Trot, Canter), (3) Carriage Drivability (Dressage Test, Obstac...
Urbanization is among the most important and globally rapidly increasing anthropogenic processes and is known to drive rapid evolution. Habitats in urbanized areas typically consist of small, fragmented and isolated patches, which are expected to select for a better locomotor performance, along with its underlying morphological traits. This, in turn, is expected to cause differentiation in sele...
In this study, 12 retro transposons-based primers (7 IRAP and 5 REMAP primers) and general and mixed linear models (GLM and MLM) were used to identify molecular markers associated to 22 agro morphological traits in 48 different confectionery sunflower accessions. Studied accessions were divided into three main groups using Neighbor Joining method. Study of population structure as a prerequisite...
this experiment was conducted to evaluate the effects of different levels of portulaca oleracea (po),medicinal plant, on performance, egg traits, blood biochemical and immunity parameters of laying hens. one hundred eighty hi-line (w-36 strain) mature laying hens 65 up to 76 weeks of age were allotted in a completely randomized design consisting of 5 treatments and 3 replicates (12 birds per re...
