The research was conducted on the effect of bird broilers fed with different hybrid rye doses on the fatty acids profile in muscle. The first experiment was performed on 3 geese broilers groups fed with hybrid rye, oats or hybrid rye and oats mix in proportion 1:1. No effect of the hybrid rye feeding of geese on the SFA level in meat was observed, but the MUFA level was significantly higher and PUFA level and n-6/n-3 PUFA ratio were significantly lower than in geese fed with oats. The second experiment was performed on 3 chicken broiler groups fed with mix of corn, wheat, soybean meal and rapeseed oil (control group), and fed with an addition of 10% or 20% hybrid rye in diet (experimental groups). No effect of hybrid rye feeding of chicken broilers on the meat quality and SFA level was observed. However, the MUFA level was higher and the PUFA level and n-6/n-3 PUFA ratio were lower in meat of chicken broilers fed with hybrid rye. In conclusion hybrid rye is a healthy ingredient in the diet of studied birds and may be used up to 20% in chicken broilers and 50% in the diets of geese. A 100% hybrid rye in geese diet caused lower final body weight.
本研究旨在探讨不同剂量杂交黑麦饲喂肉禽对其肌肉脂肪酸谱的影响。第一个实验选取3组肉鹅，分别饲喂杂交黑麦、燕麦，以及杂交黑麦与燕麦按1:1比例混合的饲料。结果发现，饲喂杂交黑麦对鹅肉中饱和脂肪酸（SFA）水平无影响，但单不饱和脂肪酸（MUFA）水平显著高于饲喂燕麦的鹅，而多不饱和脂肪酸（PUFA）水平及n-6/n-3多不饱和脂肪酸比例则显著低于饲喂燕麦的鹅。第二个实验选取3组肉鸡，一组饲喂玉米、小麦、豆粕和菜籽油的混合物（对照组），另外两组在日粮中添加10%或20%的杂交黑麦（实验组）。结果发现，饲喂杂交黑麦对肉鸡的肉质和饱和脂肪酸水平无影响。然而，饲喂杂交黑麦的肉鸡肌肉中，单不饱和脂肪酸水平较高，而多不饱和脂肪酸水平及n-6/n-3多不饱和脂肪酸比例较低。总之，杂交黑麦是所研究禽类日粮中的一种健康成分，在肉鸡日粮中可添加至20%，在肉鹅日粮中可添加至50%。在肉鹅日粮中使用100%的杂交黑麦会导致最终体重降低。
