Abstract


In order to work out a mathematical modelling,  the growth process on quail chicks was studied. The experiment used 55 one day-old quail chicks raised in cages, assigned to 5 randomized groups (one control and four experimental groups). The experimental period was of 42 days. The chicks received isocaloric diets with three levels of feeding (ad libitum, 90% and 80% of ad libitum) and three protein levels (according to the standard and lower with 5% and 10%). The growth energy and the growth speed were significantly influenced by the level of feeding and by the dietary protein level. The highest daily weigh gain was assessed, by mathematical modelling, at 17.12 g, achieved at 25 days. The weight at maturity (39 days) was assessed, by mathematical modelling, with the highest value being 156 g.

Key words: mathematical modelling, quail
