Researchers Viper’s Strike Nature First Time
2017/2/16
Feeding is paramount to the survival of almost every animal, and just about every living organism is eaten by another. Not surprisingly, the animal kingdom shows many examples of extreme specializatio...
Asymmetries in Chickens from Lines Selected and Relaxed for High or Low Antibody Titers to Sheep Red Blood Cells
Chicken Asymmetry Selection Wattle Stress
2016/5/17
Wattle length, width, and area were measured to classify bilateral asymmetries in four lines of chickens. The lines were the S26 generation of White Leghorns selected for high (HAS) or low (LAS) respo...
Effect of High Dietary Carbohydrate on the Growth Performance, Blood Chemistry, Hepatic Enzyme Activities and Growth Hormone Gene Expression of Wuchang Bream (Megalobrama amblycephala) at Two Temperatures
Temperature Growth Serum Parameters Hepatic Enzymes Activities
2016/5/17
The effects of high carbohydrate diet on growth, serum physiological response, and hepatic heat shock protein 70 expression in Wuchang bream were determined at 25°C and 30°C. At each temperature, the ...
For chimpanzees, just like humans, teasing, taunting and bullying are familiar parts of playground politics. An analysis of 12 years of observations of playground fights between young chimpanzees in E...
A Genome Wide Association Study on Age at First Calving Using High Density Single Nucleotide Polymorphism Chips in Hanwoo (Bos taurus coreanae)
Single Nucleotide Polymorphism Whole Genome
2016/5/17
Age at first calving is an important trait for achieving earlier reproductive performance. To detect quantitative trait loci (QTL) for reproductive traits, a genome wide association study was conducte...
