There is growing interest in adding marine algae to poultry feed rations. The aim of the present study is to examine the effect of various inclusions of sp., sp., and sp. on productive performance, serum proteins, liver proteins, meat quality, and antioxidant activity in broiler chickens. There were seven dietary treatments (TRTs) as follows: TRT 1 was the control group without algae; TRT 2 was enriched with sp. at 1% of the diet; TRT 3 with sp. at 2% of the diet; TRT 4 with sp. at 0.5% of the diet; TRT 5 with sp. at 1% of the diet; TRT 6 with sp. at 5% of the diet; TRT 7 with sp. at 7.5% of the diet. Each treatment was replicated ten times, with 17 birds per replicate, and the analyses were performed in triplicates. Results of the feed rations proximate analyses revealed that the formulated diets contained the required amounts of protein, fat, fiber, ash, and moisture, to be fed to the broiler chickens. There was no effect of marine algae on the production performance parameters of the birds. All the enriched birds performed normally as the control group. It was shown that enriching the broiler diet with 1% sp. Induced an increase in the total serum proteins, while sp. algal inclusion reduced the total serum proteins, compared to the control group. At five weeks of age, enriching broiler diets with 5% sp. resulted in a higher concentration of total serum protein-C than the control group and the group enriched with 7.5% inclusion. Enriching the diet of 3- wks old broilers with sp. at 2% elevated the proportions of serum LFABP. The maximum proportion of omega 6 fatty acid (∑n-6) was observed in the group of birds that received the control diet, while the proportion of omega 3 fatty acid (∑n-3) was highest in the algae-enriched groups. The results showed that all algal inclusions lowered the ratio of omega-6 to omega-3 fatty acids (∑n-6:∑n-3). Enriching broiler chickens with at 5% and 7.5% increased the HDL concentration, compared to the control group. The palatability of meat for color, texture, flavor, appearance, smell, and overall acceptability was not negatively affected by algal inclusions. All algal inclusions enhanced the anti-oxidative status of broilers and lipid oxidative stability of the stored feed rations. In general, it can be concluded that marine algal inclusions showed no effect on the productive performance of the broiler chickens and can be used without any detrimental effects in poultry feed rations.
将海藻添加到家禽日粮中的兴趣日益浓厚。本研究的目的是考察不同比例的[具体藻类1]、[具体藻类2]和[具体藻类3]对肉鸡生产性能、血清蛋白、肝脏蛋白、肉质和抗氧化活性的影响。共有七种日粮处理（TRTs）如下：TRT 1为不添加藻类的对照组；TRT 2日粮中添加1%的[具体藻类1]；TRT 3日粮中添加2%的[具体藻类2]；TRT 4日粮中添加0.5%的[具体藻类3]；TRT 5日粮中添加1%的[具体藻类1]；TRT 6日粮中添加5%的[具体藻类2]；TRT 7日粮中添加7.5%的[具体藻类3]。每个处理重复十次，每个重复组有17只鸡，分析进行三次重复。日粮近似分析结果表明，所配制的日粮含有饲喂肉鸡所需量的蛋白质、脂肪、纤维、灰分和水分。海藻对鸡的生产性能参数没有影响。所有添加藻类的鸡表现与对照组正常无异。结果表明，日粮中添加1%的[具体藻类1]可使血清总蛋白增加，而与对照组相比，添加[具体藻类2]可降低血清总蛋白。在五周龄时，日粮中添加5%的[具体藻类2]使血清总蛋白-C浓度高于对照组和添加7.5%[具体藻类2]的组。日粮中添加2%的[具体藻类3]使3周龄肉鸡血清LFABP比例升高。对照组鸡群中ω-6脂肪酸（∑n-6）比例最高，而在添加藻类的组中ω-3脂肪酸（∑n-3）比例最高。结果表明，所有藻类添加均降低了ω-６与ω-３脂肪酸的比例（∑n-6:∑n-3）。与对照组相比，日粮中添加5%和7.5%的[具体藻类3]可提高肉鸡高密度脂蛋白（HDL）浓度。藻类添加对肉的颜色、质地、风味、外观、气味和总体可接受性等适口性没有负面影响。所有藻类添加均增强了肉鸡的抗氧化状态和储存日粮的脂质氧化稳定性。总体而言，可以得出结论，添加海藻对肉鸡的生产性能没有影响，可以在家禽日粮中使用而无任何有害影响。
