Quality of Eggs and Hatching Traits in Two Slow-Growing Dual-Purpose Chicken Lines Reared Conventionally or on Pasture

The quality of eggs and the hatching traits of two slow-growing lines – La Belle (LB) and Bresse Gauloise (BB) reared under conventional or alternative system with pasture access were compared. The birds of both lines in the study were at the age of 27-37 weeks. Two-way ANOVA was used to assess the effect of the rearing system as well as the line on the quality characteristics of the eggs and h...

Ribonuclease Activity in Some Transplantable Rat Hepatomas.

Several parameters of ribonuclease activity have been determined in a series of transplantable rat tumors and liver from the host rats. These include ribonuclease inhibitor activity, pH activity curves, and the distribution and specific activity of acid and alkaline ribonuclease in subcellular fractions. For those hepatomas studied, compared with liver from the tumor-bearing animal, the followi...

The heterogeneity of DNA polymerases in rat liver and hepatomas.

Two distinct plant respiratory physiotypes might exist which correspond to fast-growing and slow-growing species.

The origin of the carbon atoms in CO2 respired by leaves in the dark of several plant species has been studied using 13C/12C stable isotopes. This study was conducted using an open gas exchange system for isotope labeling that was coupled to an elemental analyzer and further linked to an isotope ratio mass spectrometer (EA-IRMS) or coupled to a gas chromatography-combustion-isotope ratio mass s...
