Toxicity and Biological Value of Broiler Chicken Meat in case of Feeding the “Aquasan” Acidifier
Employees of the Ternopil Research Station on the basis of organic and inorganic acids created a new liquid acidifier for broiler chickens called the “Aquasan”. It positively affects the preservation, productivity and constant microflora of the digestive tract in chickens. An important indicator of meat is its harmlessness and biological value. The purpose of the paper was to research the toxicity and biological value of chicken meat in case of feeding the stock with the “Aquasan” acidifier. The research was conducted on three groups of chicken broilers of the breed Ross 308–50 heads in each group. The first group of chickens was the control one, and the second group of chickens was fed with 0.1 % solution of the “Aquasan” acidifier from the 27th day of fattening within 10 days (27th–31st and 34th–38th days). The growing period lasted 43 days. Toxico-biological evaluation of chicken meat was carried out by express method using infusorias Tetrachymena pyriformis. Study of toxicity of pectoral and thigh muscles of the chickens have shown that within 24 hours of observing the infusorias, there was no death or inhibition of growth in an environment. Only on the 24th hour of observing in the experimental and control groups, there were infusorias with changes in shape and nature of movement in the amount of 0.1–0.2% cultures. The results of the research indicate that there is no acute and subacute toxicity of broiler meat in case of feeding the Acquasan acidifier. After 96 hours of research, 0.5–0.6 % of dead infusorias was found in samples of pectoral and thigh muscles in both groups. Also, there were infusorias with changes in shape and nature of movement on the 4th day, 0.3–0.4% and 0.2–0.3% respectively. There were no changes in growth of infusorias in the test group. Comparing the results of studies with control samples, it can be noted that the broiler chicken meat does not exhibit chronic toxicity. During 96 hours of research on the toxicity of chicken meat, no significant changes were found in the experimental group. Consequently, chicken meat from broilers grown with the use of “Aquasan” acidifier according to the express method is non-toxic, i.e. harmless for consumption. During the study of biological value of chicken meat, calculation of number of infusorias who grew up on the 4th day in the environment of the research samples of pectoral and thigh muscles, showed a lack of credible changes in their number as compared with the control. The absence of a reliable decrease in the relative biological value of meat indicates the high quality of the broiler chicken product in case of feeding them with the “Aquasan” acidifier.
