Plasma insulin-like growth factor-1 (IGF-I) concentration taken post weaning from 1240 Bos Taurus beef cattle were used to estimate the heritability of the trait and to investigate its genetic relationship with various growth and carcase traits. IGF-I had a heritability estimate of 32% and was positively genetically correlated with various measures of carcase fatness, both on the live animal (s...
Restricted maximum likelihood (REML) was used to determine the choice of statistical model, additive genetic maternal and common litter effects and consequences of ignoring these effects on estimates of variance–covariance components under random and phenotypic selection in swine using computer simulation. Two closed herds of different size and two traits, (i) pre-weaning average daily gain and...
Data from the birth weight (BW), the average daily gain from birth to weaning (ADG) and the weaning weight (WW) of 1182, 1099 and 1099 lambs were respectively collected and applied to estimate the maternal effects on heritabilities as well as on the determination of the environmental factors. The data were collected from Shahrbabak Sheep Breeding Research Station within five year, from 1993 to ...
Background and Objectives: Progressive muscle relaxation is a non-invasive, cost-effective and complication less method which can be performed independently by the individual. Considering the importance of psychological problems during pregnancy, the purpose of this study was to evaluate the effect of progressive muscle relaxation counseling on anxiety among primigravida women referred to healt...
Objective. To date, no studies have directly examined the effects of cognitive trait hostility on prospectively assessed sleep quality. This is important as individuals with heightened trait hostility demonstrate similar patterns of reactivity to perceived stressors as is often reported by poor sleepers. The present study hypothesized that increased trait hostility is associated with poorer sub...
Historically, organizational and personality psychologists have ignored within-individual variation in personality across situations, or treated it as measurement error. However, consistent with whole trait theory (Fleeson, 2012), which conceptualizes personality as a system of stable tendencies and patterns of intraindividual variation along the dimensions of the Big Five personality traits (C...
Historically, organizational and personality psychologists have ignored within-individual variation in personality across situations or have treated it as measurement error. However, we conducted a 10-day experience sampling study consistent with whole trait theory (Fleeson, 2012), which conceptualizes personality as a system of stable tendencies and patterns of intraindividual variation along ...
The weighing records of 18 crossbred females with average live weight of 14.7 ± 3.14 kg were analyzed to study the relationship of the growth of crossbred hair sheep with some zoometric measures. The weight was established and took the measures thoracic perimeter, cannon perimeter, body length, neck length, hip amplitude, ischial amplitude, withers height and croup height. All parameters were s...
