摘要: Abstract Trials were conducted to evaluate growth rates of two age groups young ringnecked pheasants (Phasianus colchicus) fed dietary protein levels (28 and 18%) at environmental temperatures (warm cool). Birds the high diet gained faster more efficiently than those low during first 24 days posthatching. Beyond that time, birds just as well on 18% CP diet. Heat stress slowed weight gains, in older (45-day-old) younger (24-day-old) birds, particularly when was fed.
