Previous studies have identified peanut meal prepared from normal-oleic peanuts as a suitable and economical ingredient for broiler feed. However, to date, no studies have examined the use of new, high-oleic peanut (HO-PN) cultivars as a feed ingredient for poultry. This project aimed to determine the effect of HO-PNs as a feed ingredient for broiler chickens on the quality and sensory attributes of the meat produced. To test 3 experimental diets, male broiler chicks were randomly placed, at hatch, in raised-wire cages, in 10 replicate pens per treatment with 10 chicks per cage. For 6 wk, chicks were fed, ad libitum, one of the three isocaloric, isonitrogenous diets: (1) a conventional soybean meal plus corn control diet, (2) 10 to 12% HO-PN + corn diet, or (3) a control corn diet spiked with ≈6.0% oleic fatty acid oil (OA). At 42 D, 3 broilers per pen (30 per treatment) were processed to determine meat quality and for consumer evaluation. Carcass weights and breast yields were reduced in broilers fed HO-PN, while leg carcass yields were greater in broilers fed HO-PN in comparison to the other groups. Chicken breast from broilers fed HO-PN had reduced meat-pH, reduced L* color values, and increased cooked loss compared to other treatments. Nevertheless, a group of 100-consumer panelists scored all 3-treatment groups similar in terms of sensory attributes for cooked chicken. While additional studies must be performed, this study suggest that HO-PN may be a suitable broiler feed ingredient.
先前的研究已经确定,由正常油酸花生制成的花生粉是一种适合且经济的肉鸡饲料成分。然而,迄今为止,尚无研究探讨将新型高油酸花生(HO-PN)品种用作家禽饲料成分。本项目旨在确定将 HO-PN 用作肉鸡饲料成分对所生产肉的质量和感官特性的影响。为了测试 3 种实验饲料,雄性肉鸡雏鸡在孵化后随机放置在高架铁丝笼中,每个处理 10 个重复笼,每个笼中有 10 只雏鸡。在 6 周的时间里,雏鸡自由采食 3 种等热量、等氮的饲料之一:(1)传统的大豆粉加玉米对照饲料;(2)10-12%的 HO-PN+玉米饲料;或(3)用约 6.0%油酸脂肪酸油(OA)强化的对照玉米饲料。在 42 天,每个笼中的 3 只肉鸡(每个处理 30 只)被处理以确定肉品质和进行消费者评价。饲喂 HO-PN 的肉鸡的胴体重和胸产量降低,而饲喂 HO-PN 的肉鸡的腿胴体产量高于其他组。与其他处理相比,饲喂 HO-PN 的肉鸡的鸡胸肉的 pH 值降低,L*颜色值降低,蒸煮损失增加。尽管必须进行更多的研究,但本研究表明,HO-PN 可能是一种适合的肉鸡饲料成分。
