Wybutosine (yW) is a tricyclic nucleoside with a large side chain found at the 3'-position adjacent to the anticodon of eukaryotic phenylalanine tRNA. yW supports codon recognition by stabilizing codon-anticodon interactions during decoding on the ribosome. To identify genes responsible for yW synthesis from uncharacterized genes of Saccharomyces cerevisiae, we employed a systematic reverse gen...
Sire genetic evaluations for protein yield, somatic cell score (SCS), productive life, and udder type traits from the US were correlated with sire evaluations for udder health from Denmark and Sweden and then the correlations were adjusted for accuracies to approximate genetic correlations. Traits from Denmark and Sweden included somatic cell count (SCC) and clinical mastitis from single-trait ...
The objective of this study was to estimate genetic parameters for milk protein fraction contents, milk protein composition, and milk coagulation properties (MCP). Contents of α(S1)-, α(S2)-, β-, γ-, and κ-casein (CN), β-lactoglobulin (β-LG), and α-lactalbumin (α-LA) were measured by reversed-phase HPLC in individual milk samples of 2,167 Simmental cows. Milk protein composition was measured as...
A Camel Research Station was established in 1990 at the central desert land of Iran named Kavir-e-loot, to evaluate productivity performance of one humped camel. The data consisted of birth weights (BW), three (W3), six (W6), nine (W9) months and yearling (W12) body weight of animals and the pedigree was registered during a period of 14 years since 1991 to 2004. The body weight traits of birth,...
black bengal goat is the heritage and one of the potential genetic resources of bangladesh. genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in black bengal bucks were estimated in this experiment. genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...
The objective of this study was to investigate the genetic relationship between body condition score (BCS) and calving traits (including calving ease and calf survival) for Ayrshire second-parity cows in Canada. The use of random regression models allowed assessment of the change of genetic correlation from 100 d before calving to 335 d after calving. Therefore, the influence of BCS in the dry ...
Sire genetic evaluations for protein yield, productive life, and selected type traits from the US were correlated with sire evaluations for disease from Denmark and Sweden and were then adjusted to approximate genetic correlations. Disease categories from Denmark included reproductive diseases, foot and leg diseases, metabolic and digestive diseases, and all diseases other than mastitis. Geneti...
We aimed to evaluate the effects of sex and linear quadratic components age dam at calving, as well apply a mixed model including maternal effect for genetic evaluation weaning (WW) yearling (YW) weights. The phenotypic database was composed by Charolais, Caracu, Aberdeen Angus, Canchim purebred crossbred animals. Single-trait analyses were performed using models that included WW YW traits, ign...
For estimating genetic parameters for body weight traits in Kourdi sheep data were collected from 1996 to 2013 in Kourdi Breeding Station in Northern Khorasan province of Iran. Studied traits were birth weight (BW), weaning weight (WW), six-month weight (6MW), nine-month weight (9MW) and yearling weight (YW). The fixed effects in the model were lambing year, sex, type of birth and age of dam. (...
Feed intake and efficiency of growth are economically important traits of beef cattle. This study determined the relationships of daily DMI, feed:gain ratio [F:G, which is the reciprocal of the efficiency of gain (G:F) and therefore increases as the efficiency of gain decreases and vice versa, residual feed intake (RFI), and partial efficiency of growth (efficiency of ADG, PEG) with growth and ...
