Chemical composition, energy and biological value of broiler chicken meat caused by various doses of selenium

Abstract

From the standpoint of modern ideas, the normal functioning of the poultry body and full implementation her of the genetic potential is impossible without the presence of selenium in the diet. The biochemical diversity of selenium puts it in a number of priority trace elements. Scientists who were studying the effects of selenium on poultry body and paid relatively little attention to the quality of the meat. In scientific experiment are studied the effect of additives different doses of selenium in compound feed on the chemical composition, energy and biological value of meat of the cross chickens-broilers COBB 500. Introduction of selenium into the feed for broiler chickens in the doses which are studied (0.3 mg/kg, 0.4 and 0.5 mg/kg) did not significantly affect to the quality of their muscle tissue although it positively affected on some indicators that characterizing its chemical composition, nutritional and biological value. Among the experimental groups, the best meat quality indicators were in the second group of chickens for which was introduced into the feed selenium from the calculation of 0.3 mg/kg. When feeding mixed feeds with selenium additives to broiler chickens it was found that it is likely to increase the concentration of this trace element in muscle tissue by 60.6-100% (P?0.001), which does not exceed the maximum permissible level (MPL). Consumption of selenium-enriched meat of broiler chickens within the limits of the physiological norms recommended in Ukraine will ensure the daily requirement of an adult in this trace element by 23.6-29.4%. This meat product can be especially useful for people who live in regions with low levels of selenium in the natural environment.

Яєчна Продуктивність Та Гематологічні Показники Курок-Несучок Під Впливом Пробіотичної Добавки

“…Основні вимоги до них -безпечність як для тварин, так і для продукції тваринництва, що використовує людина. Заборона використання антибіотиків у годівлі тварин та посилення законодавчих вимог щодо їх застосування у тваринництві, а також зростання попиту споживачів на органічну продукцію з високим рівнем безпечності змусили виробників шукати природну альтернативу для підтримки продуктивності тварин на високому рівні [4,6,14,17].…”

Selenium in natural environment and food chains. A Review

“…The concentration of element was 6.0 and 7, kg/% in chest and leg muscles of cross "Соbb" broiler poultry were raised on a selenium-deficient diet (0.08-0.10 mg/kg). The introduction of selenium supplements in mixed feed at doses of 0.2-0.4 mg/kg increased its concentration in the chest muscles of their peers to 7.3-12.4 μg/%, and in the leg muscles to 8.7-14.3 μg/% (Sobolev et. al., 2019).…”

Influence of heavy metals on hematologic parameters, body weight gain and organ weight in rats

“…Anthropogenic activity contributes to the dispersion of a large number of chemical elements involved in the migration process. Heavy metal salts, particularly Cadmium and Lead, which are highly toxic and can affect living organisms, even at low concentrations, are among the leading chemical pollutants (Ali et al, 1986;Hutyi, 2015;Gutyj et al, 2018;2019). The frequency and severity of ecologically dependent diseases resulting from anthropogenic pollution of the biosphere indicates the relevance of this problem Grynevych et al, 2018;Slivinska et al, 2019).…”

“…Thus, in case of environmental pollution by heavy metals it is proved that the manifestations of toxic action may depend on the interaction between them, which leads to change of thresholds, and therefore not only the toxicity of each component of the system but also their combined action is important (Slobodian et al, 2019). The results of many experimental studies indicate that Cadmium and Lead have a toxic effect on a number of organs and systems in mammals (Marushko et al, 2010;Petrynych et al, 2017;Ostapyuk & Gutyj, 2018;2019). Lead and Cadmium, when introduced into the body of animals, easily connect to thiol groups of apoproteins, and thus change the activity of antioxidant, microsomal and other enzymatic systems, affect the exchange of macro-and microelements, exhibit carcinogenic action (Al-Azemi et al, 2010;Stepanchuk, 2014;Lavryshyn et al, 2018;2019;.…”

The aim of the study was to determine the effect of Cadmium and Lead salts on body weight gain and rat body weights and hematological parameters.…”
