This study was aimed to evaluate the effects of (white wormwood) or olive leaf () powder supplementation on growth performance, carcass yield, and serum biochemical parameters in broilers.
The study was conducted from April to May 2017 in Chemini region, Northern Algeria. A total of 60 1-day-old Ross 308 male chicks were divided into three groups consisted of 10 chicks, in each of two replications. The chicks in Group 1 were fed with a standard commercial diet (SCD); Group 2 received the same SCD with 2% supplementation of powder; and Group 3 received the same SCD with 2% supplementation of powder. Growth performance was measured with body weights every 2 weeks, daily feed intake, feed conversion ratio (FCR), and carcass yield at the end of 42 days of rearing. Blood samples were collected to analyze serum glucose, cholesterol, triglycerides, urea, and total protein levels.
Results showed that, at 42 days of rearing, supplementation of and significantly increased (p<0.001) mean body weight (2230.10±26.38 g and 2117.42±26.38 g, respectively, vs. 2336.66±27.88 g in chicks of Group 1), but there was no significant difference (p≥0.05) among the three diets for FCR or percentage carcass yield. Among the serum biochemical parameters, glucose was significantly affected (p<0.01) by supplementation of olive leaf powder (1.90 g/L: Group 3), compared to the SCD (2.24 g/L: Group 1) or Artemisia powder (2.05 g/L: Group 2). Moreover, the supplementation of olive leaf powder in Group 3 broilers significantly affected (p<0.05) the serum cholesterol level (0.95 g/L), compared to the control diet (1.13 g/L). There was no significant difference (p≥0.05) for the other selected serum biochemical concentrations, namely triglycerides, urea, and total protein.
The supplementation of Artemisia or olive leaf powder into the diet for broilers improved body weight by about 5% or 10%, respectively, at slaughter with moderate changes in blood biochemical parameters.
本研究旨在评估添加苦艾（白蒿）或橄榄叶粉对肉鸡生长性能、胴体产量和血清生化参数的影响。
本研究于2017年4月至5月在阿尔及利亚北部的谢米尼地区进行。总共60只1日龄的罗斯308雄性雏鸡被分为三组，每组10只雏鸡，每组重复两次。第1组雏鸡饲喂标准商业日粮（SCD）；第2组在相同的SCD基础上添加2%的苦艾粉；第3组在相同的SCD基础上添加2%的橄榄叶粉。每2周测量一次体重、每日采食量、饲料转化率（FCR），并在饲养42天结束时测量胴体产量，以此来评估生长性能。采集血液样本分析血清葡萄糖、胆固醇、甘油三酯、尿素和总蛋白水平。
结果显示，在饲养42天时，添加苦艾和橄榄叶显著增加了（p<0.001）平均体重（第2组和第3组雏鸡的平均体重分别为2230.10±26.38克和2117.42±26.38克，而第1组雏鸡为2336.66±27.88克），但三种日粮在FCR或胴体产量百分比方面没有显著差异（p≥0.05）。在血清生化参数中，与标准商业日粮组（2.24克/升：第1组）或苦艾粉组（2.05克/升：第2组）相比，添加橄榄叶粉显著影响了（p<0.01）血清葡萄糖水平（1.90克/升：第3组）。此外，与对照日粮组（1.13克/升）相比，第3组肉鸡添加橄榄叶粉显著影响了（p<0.05）血清胆固醇水平（0.95克/升）。对于其他选定的血清生化浓度，即甘油三酯、尿素和总蛋白，没有显著差异（p≥0.05）。
在肉鸡日粮中添加苦艾或橄榄叶粉，在屠宰时分别使体重提高了约5%或10%，同时血液生化参数有适度变化。
