This study evaluated the effects of feed additives on the growth, blood biochemistry and intestinal health of broiler chicks. A total of 378 of broiler chicks (Ross 308) were randomly allotted to seven groups. Chicks were fed a basal diet with 0.0 (control negative), 0.0 (control positive), 0.1, 0.5, 0.12, 0.5 + 0.12 and 0.2 g Kg of Maxus, CloStat, Sangrovit Extra, CloStat + Sangrovit Extra and Gallipro Tech, respectively for 35 days. After 15 days, the chicks were inoculated with All feed additives were found to enhance growth performance and feed efficiency. The best feed conversion ratio was found in the Negative Control, CloStat + Sangrovit Extra and Gallipro Tect groups, respectively. A notable increase in villus length, total villus area, small intestine weight, ilium weight and total lesion score was found in chicks supplemented with . Besides, the dietary inclusion of phytobiotic compounds showed potential in reducing the serum Alanine aminotransferase (ALT) concentration and increasing the glucose levels. All intestine and liver histopathological signs were reduced in chicks fed a probiotic-supplemented diet. Our findings indicate that supplementation with probiotics and phytobiotics alone or in combined form can be used to enhance performance, intestine health and blood constituents against infection in broiler chicks.
本研究评估了饲料添加剂对肉鸡生长性能、血液生化指标及肠道健康的影响。总共378只罗斯308肉鸡随机分为七组。分别给雏鸡饲喂基础日粮，其中添加0.0（阴性对照）、0.0（阳性对照）、0.1、0.5、0.12、0.5 + 0.12及0.2 g/kg的Maxus、CloStat、Sangrovit Extra、CloStat + Sangrovit Extra和Gallipro Tech，持续35天。15天后，给雏鸡接种……所有饲料添加剂均能提高生长性能和饲料效率。阴性对照、CloStat + Sangrovit Extra和Gallipro Tect组的饲料转化率分别最佳。在添加……的雏鸡中，绒毛长度、总绒毛面积、小肠重量、回肠重量及总病变评分显著增加。此外，日粮中添加植物源生物活性物质有降低血清丙氨酸转氨酶（ALT）浓度和提高葡萄糖水平的潜力。饲喂添加益生菌日粮的雏鸡，所有肠道和肝脏组织病理学症状均减轻。我们的研究结果表明，单独或联合添加益生菌和植物源生物活性物质可用于提高肉鸡的生产性能、肠道健康及血液成分，以抵抗……感染。
