The aim of this study was the assessment of various levels of date palm kernel (DPK) on the growth performance of broilers.
A 250-day-old broiler chicks were randomly selected and categorized into five groups (50 chicks/group) contained A (control), B, C, D and E fed with 0%, 1%, 2%, 3% and 4% levels of DPK in balanced ration, respectively, for 6 weeks. Feed and water intake were recorded daily in the morning and evening. The data for feed intake, water intake, live body weight, and feed conversion ratio (FCR) were recorded from all birds regularly. The carcass weight and percentage obtained via six slaughtered birds were randomly selected from each group. Finally, economic aspects of the rations evaluated.
The most feed intakes of broilers were recorded in Group A (3915.1 g) that was significantly higher than Groups D and E. The highest water intake was in Group E (9067.78 ml) that was significantly higher than Group A and control group. Live body weight was highest in Group E (979.85 g) than Groups B, C, and control group. The best growth weights were determined significantly in Groups D (1921.96 g) and E (1935.95 g). The lowest FCRs were indicated significantly in Groups D (1.97 g/g) and E (1.92 g/g) than Groups B and A. The highest carcass weights were recorded in Groups D (1214.01 g) and E (1230.88 g) that were significantly more than other groups. Dressing percentages in Groups D (61.76%) and E (62.17%) were higher than other groups (p<0.05). The net profits (Rs.) in Groups A, B, C, D and E were indicated 27.01, 32.77, 36.78, 43.47 and 44.51 per broiler, respectively.
It was concluded that the high levels of DPK (3-4%) significantly decreased broiler feed intake and increased water intake, live body weight, growth weight, carcass weight, dressing percentage, net profit per bird and also had positive effects on growth of broilers.
本研究旨在评估不同水平的枣椰核（DPK）对肉鸡生长性能的影响。
随机选取250日龄的肉鸡雏鸡，分为五组（每组50只雏鸡），分别为A组（对照组）、B组、C组、D组和E组，在平衡日粮中分别添加0%、1%、2%、3%和4%水平的DPK，为期6周。每天早晚记录采食量和饮水量。定期记录所有鸡的采食量、饮水量、活体体重和饲料转化率（FCR）数据。从每组中随机选取6只屠宰鸡，获取胴体重和屠宰率。最后，评估日粮的经济方面。
A组肉鸡的采食量最高（3915.1克），显著高于D组和E组。E组的饮水量最高（9067.78毫升），显著高于A组和对照组。E组的活体体重最高（979.85克），高于B组、C组和对照组。D组（1921.96克）和E组（1935.95克）的生长体重显著最佳。D组（1.97克/克）和E组（1.92克/克）的FCR显著低于B组和A组。D组（1214.01克）和E组（1230.88克）的胴体重最高，显著高于其他组。D组（61.76%）和E组（62.17%）的屠宰率高于其他组（p<0.05）。A组、B组、C组、D组和E组每只肉鸡的净利润分别为27.01、32.77、36.78、43.47和44.51卢比。
得出的结论是，高水平的DPK（3 - 4%）显著降低了肉鸡的采食量，增加了饮水量、活体体重、生长体重、胴体重、屠宰率、每只鸡的净利润，并且对肉鸡的生长也有积极影响。
