Eggs are an economical source of nutrients for a healthy diet and life. Increased egg production and consumption in the developed and developing world would significantly improve food and nutrition security. It is especially important for the mental development of growing children (Food and Agriculture...

The effect of the presence or absence of the opposite sex on egg production and semen quality of breeder turkeys was evaluated. Ninety-six female and 36 male Medium White turkeys were used in this study. Two males were released, individually, into each of eight pens of females for 15 min ...
How- ever, even in these environments attempts to calculate Hirst & McKinnon: Does egg production represent adult female copepod growth? 181 output represent the net growth of the female when measured over 24 h or multiples of this (e.g. 48 h, 72 h, etc). The aims of the present ...
An initial signal, at very early stage during the embryonic development, is required to initiate the sex determination cascade; in the absence of this signal the opposite sex develops in a default mode12. In D. melanogaster the initial sex-determining signal, provided by the X:A ratio13 or ...
