The effect of genotype and pasture on chickens performance and digestive tract development

Original language description

The aim of the study was to estimate the pasture intake in different genotypes and to evaluate the effect of genotype on carcass quality and digestive tract development. Three different genotypes were involved in the experiment; fast growing Ross 308 both sexes, slower growing JA 757 both sexes and layer-type cockerels ISA Dual, fifty chickens of each genotype. From ten days of age all hybrids were fed on fresh pasture in separate feeders to accustom this feed. Since day eighteen in Ross 308 and JA 757 and since day twenty-seven in ISA Dual daily pasture intake was observed. The experiment was finished when pasture intake plateau was achieved in each hybrid. Consequently chickens were slaughtered at the age 49 in Ross 308, 64 in JA 757 and 90 in ISA Dual. The maximal daily pasture intake was significantly the highest in ISA Dual cockerels 25.8g in comparison with JA 757 and Ross 308 (16.1, 13.1 g/d respectively, P&lt;0.05). Both length of intestine and caeca were shorter in ISA Dual in comparison with JA 757 and Ross 308 (P&lt;0.05). The lowest weight of gizzard was found in Ross 308. Carcass quality was the best in Ross 308 including the lowest proportion and weight of abdominal fat (P&lt;0.05). Intake of pasture improve feed conversion ratio (Ross 308 1.50, JA 757 1.86, ISA Dual 2.49).
