Estimation of genetic trends is necessary to monitor and evaluate selection programs. The objective of this study was to estimate the genetic trends for milk yield in Iranian Holsteins cows using random regression test day model. Data set was consisted of 743205 test-day records from 1991 to 2008, which were collected by the Animal Breeding Centre of Iran. Breeding, environmental and phenotypic...

Plasma carcinoembryonic antigen (CEA) levels were studied in 272 members of six pedigrees manifesting the cancer family syndrome and in 191 normal controls. The CEA distributions per se were transformed to square root CEA (VCEA) as a correction for skewness and kurtosis. Duration of smoking and age showed a positive correla tion with the level of NCEA in both family members and controls. Distri...

Anxiety and Depression are currently the two most prevalent psychiatric disorders worldwide, affecting around 30% 16,6% of people, respec[1]tively. Genetic factors play a key role in responsibility for these disorders, with heritability estimates ranging from to 40% anxiety depres[1]sion. Although causes not fully known, many studies seek unravel their genetic bases. In this context, study, thr...

in this study, the number of 1802 longevity records of ewes collected during 1989 to 2010 in breeding station of lori-bakhtiari sheep flocks were used to estimate of genetic, environmental and phenotypic trends for economic lifetime. the breeding values of a ewe’s lifetime were estimated by restricted maximum likelihood procedure under an animal model of univariate analysis. the best linear unb...

to conserve the genetic resources and identify the strong and weak points in sistan watermelon accessions and compare these with improved cultivars of: sugarbaby and fairfax, an experiment was carried out, based on rectangular lattic design of two replications in 2007. the morphological traits studied, included plant length, plant weight, seed weight, fruit number, fruit length, fruit width, su...
