in order to identify the segre qtl affecting growth traits on the end region of chromosome 18 in a lori-bakhtiari sheep population, 162 animals from 5 paternal half-sib families were taken to be studied. phenotypic data included records of birth weight (bwt), weight at one month of age (w1), weaning weight (wwt), weight at six months of age (w6), chest circumference (gi6), body length (lg6), wi...

In aquaculture, growth and sex are economically important traits. To accelerate genetic improvement in increasing growth in salt-tolerant tilapia, we conducted QTL mapping for growth traits and sex with an F2 family, including 522 offspring and two parents. We used 144 polymorphic microsatellites evenly covering the genome of tilapia to genotype the family. QTL analyses were carried out using i...

Research into the relationship between body sway, aim-point fluctuation, and performance in pistol shooting has been inconclusive. The present study reexamined this relationship on an interindividual basis, as done in previous studies, and via intraindividual analysis, not previously examined. Five elite pistol shooters performed 20 shots similar to competition conditions. For each shot, body-s...

Pearl millet is a staple food crop for millions of people living in the arid and semi-arid tropics. Molecular markers have been used to identify genomic regions linked to traits of interest by conventional QTL mapping and association analysis. Phenotypic recurrent selection is known to increase frequencies of favorable alleles and decrease those unfavorable for the traits under selection. This ...

This study examined the effects of quantisation of force plate data used to measure body sway and the relationship between this body sway, aim point fluctuation and performance in shooting. Quantisation error in and resolution of selected body sway parameters were calculated from force plate data sampled using 12-bit and 16-bit analog to digital conversion (ADC). It was concluded that 12-bit AD...

Turkeys, liners, waterers, litter, air, and feed weighbacks were sampled for Salmonella. Salmonella species S. simsbury, S. kentucky, S. montevideo, S. senftenberg, and S. ealing were identified at a rate of 54.9, 38.0, 2.8, 2.8, and 1.4% respectively. All isolates were subjected to Salmonella-specific polymerase chain reaction (PCR) and were confirmed as Salmonella-positive by the predicted pr...
