The management practices implemented by the poultry sector as using some nutritional additives in the early stage of a bird's life can potentially detect other challenges to production development in the poultry farms. Many potential supplements can be included in the early feeding as which are added to drinking water. In this study, 180 1-day-old chicks were randomly distributed into six groups to investigate the use of some nutritional supplements in drinking water of growing turkeys during 1st month of age and their effect on growth performance, carcass traits, meat quality, leg problems, blood profile and oxidative status. Birds that were supplied with tap water were considered the control group (C), whereas the birds that received the 1st, 2nd, 3rd, 4th and 5th treatments (T1, T2, T3, T4 and T5, respectively) were supplied with drinking water containing 10% sugar syrup, molasses, lemon juice, skim milk and fresh egg albumin respectively. The different water additives significantly (p < 0.05) affected the body weight (BW) and body weight gain (BWG) at all studied ages except for the BW at 4 weeks old and BWG at 0-4 weeks old and 8-12 weeks old. Significant effects of the treatments on the feed consumption (FC) and feed conversion ratio (FCR) were not observed during the experiment, and the treatments did not cause significant differences (p < 0.05) in the carcass cut-up traits, bone measurements, body temperature, plumage conditions, mortality rates and blood parameters except for IgA (p = 0.043). The activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) was improved in the treatment groups with 10% molasses and lemon juice respectively. The total antioxidant capacity (T-AOC) and catalase (CAT) activities were enhanced in the treatments compared with the control group. The plasma malondialdehyde (MDA) levels were decreased with the sugar syrup, molasses and lemon juice treatments compared with those in the control and other groups. Supplementation of molasses or lemon juice to drinking water of turkeys during the 1st month of age resulted in a higher profit margin in comparison with the control group. The results showed that birds supplied with water containing 10% molasses or lemon juice during the growing period presented an improved growth performance, immune response, antioxidant status and economic efficiency.
家禽养殖部门实施的管理措施，如在禽类生命早期使用一些营养添加剂，可能会发现家禽养殖场生产发展面临的其他挑战。许多潜在的补充剂可包含在早期饲料中，并添加到饮用水中。在本研究中，180只1日龄雏鸡被随机分为六组，以研究在1月龄生长火鸡的饮用水中使用一些营养补充剂及其对生长性能、胴体性状、肉质、腿部问题、血液指标和氧化状态的影响。供应自来水的禽类被视为对照组（C），而接受第1、2、3、4和5种处理（分别为T1、T2、T3、T4和T5）的禽类分别供应含有10%糖浆、糖蜜、柠檬汁、脱脂牛奶和新鲜蛋清的饮用水。除4周龄体重以及0 - 4周龄和8 - 12周龄的体重增加外，不同的饮水添加剂在所有研究年龄对体重（BW）和体重增加（BWG）均有显著（p < 0.05）影响。实验期间未观察到处理对采食量（FC）和饲料转化率（FCR）有显著影响，且处理在胴体分割性状、骨骼测量、体温、羽毛状况、死亡率和血液参数方面未引起显著差异（p < 0.05），但IgA除外（p = 0.043）。分别添加10%糖蜜和柠檬汁的处理组中超氧化物歧化酶（SOD）和谷胱甘肽过氧化物酶（GSH - Px）的活性得到改善。与对照组相比，处理组的总抗氧化能力（T - AOC）和过氧化氢酶（CAT）活性增强。与对照组和其他组相比，糖浆、糖蜜和柠檬汁处理降低了血浆丙二醛（MDA）水平。与对照组相比，在1月龄火鸡的饮用水中添加糖蜜或柠檬汁可获得更高的利润率。结果表明，在生长期间供应含10%糖蜜或柠檬汁饮水的禽类生长性能、免疫反应、抗氧化状态和经济效益均有所改善。
