Ограничение использования антибиотиков при выращивании птиц во многих странах подогрело интерес к альтернативным продуктам, таким как фитопрепараты (группа натуральных продуктов), которые в последние годы стали предметом многих исследований. Цель работы – оценить влияние биологически активных растительных органических веществ на химический, жирно- и аминокислотный состав мышц и печени цыплят-бройлеров. Исследования выполняли на 125 головах 7-суточных цыплятах-бройлерах (кросс Арбор Айкрес), разделенных на 5 групп (n = 25). Продолжительность эксперимента – 42 дня. Контрольная группа получала основной рацион (ОР); I опытная группа – ОР + гамма-лактон в дозе 0,1 мл/кг корма/сут; II опытная – ОР + гамма-лактон в дозе 0,1 мл/кг + коричный альдегид в дозе 55 мг/кг корма/сут; III опытная – ОР + гамма-лактон в дозе 0,1 мл/кг + 7-гидроксикумарин в дозе 2 мг/кг корма/сут; IV опытная – ОР + гамма-лактон в дозе 0,1 мл/кг, коричный альдегид в дозе 55 мг/кг + 7-гидроксикумарин в дозе 2 мг/кг корма/сут. В результате исследования установлено, что молодняк опытных групп превосходил сверстников контрольной по накоплению в грудных мышцах жира: I группа на 0,43 %, II – на 0,88 % (Р≤0,05), III – на 0,82 % (Р≤0,05) и IV группа – на 0,40 %. Птица II и IV групп по содержанию в бедренной мышце белка превосходила аналогов контрольной группы на 0,87 и 0,82 % соответственно. В грудных и бедренных мышцах бройлеров III группы больше накапливалось жирных кислот относительно контроля: пальмитолеиновой на 0,5 и 0,3 %, стеариновой на 0,2 % (только в бедренных мышцах), олеиновой на 1,1 % (Р≤0,05) (только в грудных мышцах), линолевой на 1,5 (Р≤0,05) и 3,1 % (Р≤0,01). При введении в рацион гамма-лактона в чистом виде наблюдали наибольшее отложение в бедренных мышцах аргинина на 0,77 %, лизина – на 2,64 % (Р≤0,05), лейцина + изолейцина – на 2,1 % (Р≤0,05), валина – на 0,83 %, серина – на 1,57 % (Р≤0,05), аланина – на 1,22 % (Р≤0,05) по отношению к контрольной группе.

The restriction of the use of antibiotics in poultry farming in many countries has fueled interest in alternative products such as herbal preparations (a group of natural products), which have been the subject of numerous studies in recent years. The aim of the study was to evaluate the effect of biologically active plant organic substances on the chemical, fatty and amino acid composition of muscles and liver of broiler chickens. The studies were performed on 125 7-day-old broiler chickens (Arbor Acres cross), divided into 5 groups (n = 25). The duration of the experiment was 42 days. The difference was that the control group received the basal diet; experimental group I – the basal diet + gamma lactone at a dose of 0.1 ml/kg of feed/day; experimental group II – the basal diet + gamma lactone at a dose of 0.1 ml/kg + cinnamaldehyde a dose of 55 mg/kg of feed/day; experimental group III – the main diet + gamma lactone at a dose of 0.1 ml/kg + 7-hydroxycoumarin at at a dose of 2 mg/kg of feed/day; experimental group IV – the main diet + gamma lactone at a dose of 0.1 ml/kg + cinnamic aldehyde at a dose of 55 mg/kg + 7-hydroxycoumarin at a dose of 2 mg/kg of feed/day. The study found that the young birds from the experimental groups exceeded their peers from the control group in fat accumulation in the pectoral muscles: I group by 0.43 %, II – by 0.88 % (P≤0.05), III – by 0.82 % (P≤0.05) and IV group – by 0.4 %. Birds from groups II and IV in terms of protein content in the femoral muscle exceeded their counterparts from the control group by 0.87 and 0.82 %, respectively. In the breast and thigh muscles of broilers of group III, fatty acids accumulated more compared to the control: palmitoleic by 0.5 and 0.3 %, stearic by 0.2 % (only in the thigh muscles), oleic by 1.1 % (P≤0.05) (only in the breast muscles), linoleic by 1.5 (P≤0.05) and 3.1 % (P≤0.01). When feeding pure gamma lactone with the diet, the highest deposition of arginine by 0.77 %, lysine by 2.64 % (P≤0.05), leucine + isoleucine by 2.1 % (P≤0.05), valine by 0.83 %, serine by 1.57 % (P≤0.05), alanine by 1.22 % (P≤0.05) in the femoral muscles was observed in relation to the control group.
