Basic factors affecting efficiency in animal breeding


, : Basic factors affecting efficiency in animal breeding. World Review of Animal Production 27(1): 93-96

On the basis of an analysis of data recorded in the British beef cattle recording scheme, the following conclusions were reached: (1) more cows with high values for most probable producing ability (MPPA) were found in top herds; (2) more calves from herds with a high proportion of cows with high values for MPPA were performance tested at central stations; (3) breeding values and their accuracies were higher for top herds.

In this Letter, a novel silica microsphere resonator (MSR) embedded with iron-oxide nanoparticles, which possesses broadband all-optical wavelength tunability, is demonstrated. It is generated by using in-line 1550 nm laser ablation of a microfibe...

At water temperatures of 21 degrees to 28.5 degrees C, transit time of digesta of bighead carp (Aristichthys nobilis), 13-2850 g, when fed at 5.7-2% of body weight, was 7.1 to 12.8 h. Transit time was shorter in larger fish due to higher speed: 32...
