ABSTRACT A study was carried out to determine the effects of soybean meal replacement with different amounts of blue lupine in the diets of turkeys on the growth rate, anatomic carcass dissection data, chemical indicators of breast and thigh muscles and the content of tryptophan and oxyprolin. In total three hundred and sixty cross BIG-6 turkeys were allotted to two control and ten experimental groups of 30 one-day-old turkeys. The control group of turkeys was fed the diet containing soybean meal, whereas the trial groups were offered different amounts (from 20 to 30%) of lupines. Group 4 and 5 were additionally given probiotic mixture Bio Plus 2B and allzyme SSF, respectively. Soybean oil replacement from 20 to 30% lupine in the diet had no influence on the growth rate, dressing percentage, edible parts and abdominal fat content of turkeys. The study indicated that lupines in the diet of turkeys had a different effect on the meat quality of different genders. Lupines did not have any negative effect on the meat quality of female turkeys and 30% lupines even improved the protein value index of breast muscles. However, 20-30 and 25-30% lupines in male turkey diets lowered dry matter and protein contents in breast muscles but had no negative influence on the main quality indicators in thigh muscles. The results of the study showed that the negative effect on the male breast muscle quality might be avoided using Bio Plus 2B or allzyme SSF additives in the male diets containing 30% lupines.
