Forty-eight females from the Botucatu Genetic Group were used in each season (warm or cool), starting at the age of 70 days, housed in groups of four per cage up to 119 days, and reared in dividually from 120 to 140 days of age. The high-density diet was formulated to contain, on a 90% DM basis, 18.4% CP, 16.5% ADF and 2,500 kcal DE kg -1 ; whereas the low-density diet was formulated to contai n 14.7% CP, 24% ADF and 2,000 kcal DE kg -1 . The experiment was conducted according to a 2x2 factorial design (t wo diets x two seasons) with repeated measures (weeks). The high-density diet promoted lower feed in take, higher final weight, and higher daily weight gain, adjusted for constant intake. But these facts alone do not warrant using a high-density diet for growing rabbit does, because it could have a negative impact during the reproduc tive phase. In the warm season, there was a reduction in feed intake and an improvement in feed efficiency. Along time, however, the mean body weight of does was similar in the two seasons. 2013 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303128707014 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
