In recent decades, the use of various feed supplements is the current trend in poultry farming, among which phytogenics serve as alternatives to feed antibiotics. This study aimed to examine the effect of feeding various doses of milk thistle extract () on the morphological and biochemical parameters of the blood in broiler chickens.
Experiments were carried out in an industrial poultry farm on broiler chickens of the Hubbard ISA F15 cross for 40 days. One control group and five experimental groups of day-old chickens were formed. The number of birds in each group was 50. Broilers of all groups received complete feed, and the experimental groups received an additional milk thistle extract at doses of 0.1, 0.5, 1.0, 1.5, and 2.0 mg/kg of body weight. Milk thistle medicinal plant extract was obtained using water-ethanol extraction followed by low-temperature vacuum drying. For the assessment of blood analyses, samples were collected from the wing vein of six chickens per group. Using unified methods recommended by the International Federation of Clinical Chemistry, the content of red blood cells, hemoglobin, white blood cells, total protein, protein fractions, triglycerides, glucose, calcium, phosphorus, and the concentration of alanine aminotransferase and aspartate aminotransferase in the blood serum were determined.
It was found that the introduction of milk thistle extract into the diet of broiler chickens with the aforementioned doses increased the number of red blood cells, hemoglobin, white blood cells in the blood, as well as a decrease in the level of albumin and an increase in the content of γ-globulins in its serum.
The authors assume that the introduction of milk thistle extract into a complete feed for broiler chickens increased the anabolic processes in their bodies, accompanied by increased use of proteins of the albumin fraction as the main material for organogenesis.
近几十年来，使用各种饲料添加剂是家禽养殖的当前趋势，其中植物源添加剂可作为饲料抗生素的替代品。本研究旨在探讨饲喂不同剂量水飞蓟提取物对肉鸡血液形态学和生化参数的影响。
在一家工业家禽养殖场对哈伯德ISA F15杂交肉鸡进行了40天的实验。组建了一个对照组和五个日龄雏鸡实验组。每组鸡的数量为50只。所有组的肉鸡均饲喂全价饲料，实验组分别额外添加体重0.1、0.5、1.0、1.5和2.0 mg/kg的水飞蓟提取物。水飞蓟药用植物提取物采用水-乙醇提取，然后低温真空干燥获得。为了评估血液分析结果，从每组六只鸡的翅静脉采集样本。使用国际临床化学联合会推荐的统一方法，测定血清中红细胞计数、血红蛋白、白细胞、总蛋白、蛋白组分、甘油三酯、葡萄糖、钙、磷以及丙氨酸氨基转移酶和天冬氨酸氨基转移酶的浓度。
发现以上述剂量将水飞蓟提取物添加到肉鸡日粮中，可增加血液中红细胞、血红蛋白、白细胞的数量，同时血清中白蛋白水平降低，γ-球蛋白含量增加。
作者认为，将水飞蓟提取物添加到肉鸡全价饲料中可增加其体内的合成代谢过程，并伴随着更多地利用白蛋白组分的蛋白质作为器官形成的主要物质。
