This study investigated the potency of bird eye pepper () of varying proportion and sieve size on growth performance and meat quality of broiler chickens. Two hundred and forty-six 2-wk-old broiler chicks were randomly allotted to six treatment groups (basal diet (B) inclusive × 2) in a 2 × 3 factorial arrangement each replicated four times (10 × 10 × 10 × 11) in a completely randomized design. Diets containing BEP of varying proportion (0, 150, and 300 g) and sieve size (0.05 and 0.1 mm) were offered in two phases, starter (14 d) and finisher (17 d). Postfeeding, 48 birds (two per replicate) were sacrificed to further evaluate performance and assess the quality of meat produced. Result obtained indicates chicks fed 150 g BEP consumed less feed compared to 300 g BEP. Also, 0 and 150 g BEP groups had better ( < 0.05) feed conversion ratio () than 300 g BEP, while 0.05 mm BEP diet improved ( < 0.05) FCR as against 0.1 mm BEP. Interaction of proportion and sieve size effects of BEP increased ( < 0.05) the final weight of the birds and suppressed ( < 0.05) feed intake for all groups as against 300 g (0.1 mm) BEP (1,576.00 g/bird; 964.20 g/bird). Feeding 150 and 300 g BEP diets lowered ( < 0.05) superoxide dismutase () production compared to 0 g BEP, while 150 g BEP diet increased ( < 0.05) catalase production over 0 g BEP. Interactive effect of proportion and sieve size of BEP reduced ( < 0.05) SOD production in 150 g (0.05 and 0.1 mm) BEP and 300 g (0.05 mm) BEP groups, followed by 300 g (0.1 mm) BEP group that had lower ( < 0.05) SOD than both basal groups. Birds fed B + 150 g (0.05 mm) BEP diet produced more ( < 0.05) catalase compared to both basal groups. Meat pH for 150 and 300 g BEP groups was significantly ( < 0.05) reduced than 0 g BEP. The Hue angle corresponds with a high value (<0.05) to 0 g BEP, while 300 g BEP showed a low value. This study has shown BEP at low concentration (150 g) screened with 0.05 and 0.1 mm sieves enhanced chick welfare, while a higher concentration (300 g) screened at 0.05 mm improved overall growth performance (endogenous antioxidant profile) at finisher phase. Broiler chickens, farmers, and meat processors will benefit from diet containing BEP screened through 0.05 mm sieve.
本研究调查了不同比例和筛网尺寸的鸟眼辣椒对肉鸡生长性能和肉质的影响。246只2周龄的肉鸡雏鸡被随机分配到六个处理组（包括基础日粮（B）×2），采用2×3析因设计，每个处理重复四次（10×10×10×11），完全随机设计。含有不同比例（0、150和300克）和筛网尺寸（0.05和0.1毫米）的鸟眼辣椒日粮分两个阶段提供，即育雏期（14天）和育肥期（17天）。喂食后，宰杀48只鸡（每个重复两只），以进一步评估性能并评估所产鸡肉的质量。获得的结果表明，与300克鸟眼辣椒组相比，喂食150克鸟眼辣椒组的雏鸡消耗的饲料更少。此外，0克和150克鸟眼辣椒组的饲料转化率（FCR）优于300克鸟眼辣椒组（P<0.05），而0.05毫米鸟眼辣椒日粮的FCR优于0.1毫米鸟眼辣椒日粮（P<0.05）。鸟眼辣椒比例和筛网尺寸的交互作用增加了（P<0.05）所有组鸡的最终体重，并抑制了（P<0.05）所有组的采食量，与300克（0.1毫米）鸟眼辣椒组（1576.00克/只；964.20克/只）相比。与0克鸟眼辣椒组相比，喂食150克和300克鸟眼辣椒日粮降低了（P<0.05）超氧化物歧化酶（SOD）的产生，而150克鸟眼辣椒日粮的过氧化氢酶产生量比0克鸟眼辣椒组增加（P<0.05）。鸟眼辣椒比例和筛网尺寸的交互作用降低了（P<0.05）150克（0.05和0.1毫米）鸟眼辣椒组和300克（0.05毫米）鸟眼辣椒组的SOD产生量；其次是300克（0.1毫米）鸟眼辣椒组，其SOD含量低于两个基础组（P<0.05）。与两个基础组相比，喂食B+150克（0.05毫米）鸟眼辣椒日粮的鸡产生了更多（P<0.05）的过氧化氢酶。150克和300克鸟眼辣椒组的肉pH值比0克鸟眼辣椒组显著降低（P<0.05）。色泽角与0克鸟眼辣椒组的高值相关（P<0.05），而300克鸟眼辣椒组的值较低。本研究表明，用0.05和0.1毫米筛网筛选的低浓度（150克）鸟眼辣椒可提高雏鸡的福利，而在育肥期，用0.05毫米筛网筛选的高浓度（300克）鸟眼辣椒可改善整体生长性能（内源性抗氧化特征）。肉鸡、养殖户和肉类加工商将从通过0.05毫米筛网筛选的含有鸟眼辣椒的日粮中受益。
