Effects of Different Amounts of Blue Lupine (L. Angustifolius L.) in The Diets of Heavy-Type Turkeys on Their Growth Rate, Carcass and Meat Qualities

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-dayold 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.

Effects of Different Dietary Levels of Blue Lupine (Lupinus angustifolius) Seed Meal With or Without Probiotics on the Performance, Carcass Criteria, Immune Organs, and Gut Morphology of Broiler Chickens

“…In the literature, blue lupine can be incorporated in broilers' diets in up to 25% of soybean meal protein and yield similar results to the soybean meal (16,18) and white lupine diets (21,22). Other researchers found that when blue lupine is fed at 30% of soybean meal protein (19,40,49) and 15% it does not have any negative influences on the production performance and health of layers (8), but increasing blue lupine to 40 and 80% of soybean meal protein decreased growth and impaired gut ecosystem and increased wet dropping (18,19). Similar results were obtained with the inclusion of 25-30% of blue lupine in turkey diets (40,49).…”

“…These results are in agreement with those reported by (40) who observed that 14.0-25.7% of white lupine in broilers' and turkeys' diets has no adverse effect on slaughter yield and carcass quality. In addition, (49) noticed that 25-30% of blue lupine does not significantly affect the dressing percentage, edible parts, and abdominal fat of turkeys. On the other hand, (55) demonstrated that probiotics at 100 and 150 g/ton feed containing Bacillus spp.…”

Similar results were obtained with the inclusion of 25-30% of blue lupine in turkey diets (40,49). In one study (2) it was observed that raw lupine fed at 40% and dehulled lupine seed meal fed at 35% significantly decreased the feed intake and growth of broiler chickens; this was visible during the first week of age and continued up to 21 d of age.…”

Phytobiotics, a Natural Growth Promoter for Poultry

“…Growers should pay particular attention to raw potato skins, which are particularly dangerous to poultry. Lupine contains quinolizidine alkaloids, which may deteriorate the nutritional and organoleptic quality of poultry meat, and cause nervousness, depression, muscle tremors and convulsions in birds [109]. Lobelia contains toxins belonging to the pyridine alkaloids that can cause neurological changes, weakness, faster breathing and lack of motor coordination in poultry.…”
