An experiment was conducted to study the effects of supplementing sprouts of pulses on performance, carcass variables, immune responses, and anti-oxidant variables in broiler chicken (day 1 to 6 weeks of age) reared during summer season in tropical region. Sprouts of black gram (BG, Vigna mungo), green gram (GG, Vigna radiata), and wild gram (WG, Vigna trilobata) were produced by soaking the pulses in water for 16 h and incubating at 37 °C for 24 h. Total phenolic content in sprouts of WG, BG, and GG was 102, 96.1, and 79.2 mg GAE/g, respectively, while the anti-radical activity in the sprouts was 61, 58, and 52%, respectively. A total of 200-day-old broiler male chicks were equally and randomly distributed in to 4 groups, each having 10 replicates of 5 chicks and housed in battery brooders in open-sided poultry house. Each of these groups was fed sprouts of BG, GG, or WG at 5% of feed intake, while the control group without feeding sprouts was kept for comparison. The trial was conducted during mid summer season (April and May, 2017). Feed conversion ratio (FCR) was reduced (P < 0.05) in broilers fed sprouted pulses compared to the control group at day 21. However, the body weight gain and FCR at 42 days of age, slaughter variables, and immune responses were not affected due to feeding of sprouted pulses. Feeding of sprouts significantly (P < 0.05) reduced lipid peroxidation and increased (P < 0.05) the activities of glutathione peroxidase, glutathione reductase, and superoxide dismutase in liver and spleen of broilers compared to the control group. Based on the results, it is concluded that oxidative stress in broiler chicken reared in tropical summer could be reduced by supplementing sprouted pulses without affecting performance, carcass variables, and immune responses.
进行了一项实验，以研究在热带地区夏季饲养的肉鸡（1至6周龄）日粮中添加豆类芽苗菜对其生产性能、胴体指标、免疫反应和抗氧化指标的影响。将黑豆（BG，绿豆）、绿豆（GG，绿豆）和野豆（WG，三裂叶野葛）浸泡在水中16小时，然后在37°C下孵育24小时，以此培育出豆芽。WG、BG和GG豆芽中的总酚含量分别为102、96.1和79.2 mg GAE/g，而豆芽中的抗自由基活性分别为61%、58%和52%。总共200只1日龄雄性肉鸡被平均随机分配到4组，每组有10个重复，每个重复5只鸡，并饲养在开放式鸡舍的层叠式育雏器中。这些组中的每一组都按采食量的5%饲喂BG、GG或WG的豆芽，而不饲喂豆芽的对照组用于比较。试验在夏季中期（2017年4月和5月）进行。与对照组相比，在第21天饲喂发芽豆类的肉鸡的饲料转化率（FCR）降低（P<0.05）。然而，42日龄时的体重增加、FCR、屠宰指标和免疫反应不受饲喂发芽豆类的影响。与对照组相比，饲喂豆芽显著（P<0.05）降低了肉鸡肝脏和脾脏中的脂质过氧化，并提高了（P<0.05）谷胱甘肽过氧化物酶、谷胱甘肽还原酶和超氧化物歧化酶的活性。根据结果得出结论，在热带夏季饲养的肉鸡中，添加发芽豆类可以降低氧化应激，而不影响其生产性能、胴体指标和免疫反应。
