The study determined the effect of the addition of 15% of camelina, flax, and sunflower seeds to iso-caloric and iso-nitrogenous diets for broiler chickens during 21-42 days of age on the nutrient digestibility, production traits, slaughter analysis parameters, hematological indices, blood mineral elements, and dietary value of breast and drumstick meat. Two hundred one-day-old broiler chickens were assigned to four groups (treatments) with five replicates (10 birds per cage, 5 females and 5 males). The experiment lasted 6 weeks. Broiler chickens receiving diets supplemented with camelina and flax seeds exhibited an increase ( < 0.05) in average body weight and a decrease ( < 0.05) in the ether extract content and energy digestibility of the diets. Moreover, the best carcass quality with a high proportion of muscles and low abdominal fat content ( < 0.05) was noted in broilers fed flax- and sunflower-enriched diets. The treatments with the oil seeds reduced the ether extract content and the calorific value of breast and drumstick muscles. The flax seeds contributed to an increase in the Fe content in drumstick muscles. Additionally, some blood parameters were influenced by the flax seed supplementation, e.g., the level of hemoglobin declined ( < 0.05) and the iron level in plasma increased ( < 0.05). It can be concluded that the camelina, flax, and sunflower seeds can be regarded as good dietary components with positive effects on the dietary value of poultry meat.
该研究确定了在21至42日龄的肉鸡等热量和等氮日粮中添加15%的荠蓝籽、亚麻籽和向日葵籽对营养物质消化率、生产性能、屠宰分析参数、血液学指标、血液矿物质元素以及胸肉和腿肉营养价值的影响。200只1日龄肉鸡被分为四组(处理组),每组五个重复(每笼10只鸡,5只母鸡和5只公鸡)。实验持续6周。接受添加了荠蓝籽和亚麻籽日粮的肉鸡平均体重增加(P<0.05),日粮的乙醚提取物含量和能量消化率降低(P<0.05)。此外,在饲喂富含亚麻籽和向日葵籽日粮的肉鸡中,观察到最佳的胴体品质,肌肉比例高且腹部脂肪含量低(P<0.05)。添加油籽的处理降低了胸肉和腿肉的乙醚提取物含量和热值。亚麻籽使腿肉中的铁含量增加。此外,补充亚麻籽对一些血液参数有影响,例如血红蛋白水平下降(P<0.05),血浆中铁水平升高(P<0.05)。可以得出结论,荠蓝籽、亚麻籽和向日葵籽可被视为对禽肉营养价值有积极影响的良好日粮成分。
