Bromine in chicken eggs, feed, and water from different regions of Ukraine

Abstract

The purpose of these studies was to analyse and compare the content of bromine in samples of chicken eggs, feed, and water from different regions of Ukraine in the dynamics of 2016 – 2020: with an increased risk of bromine in products (Kharkiv, Poltava, Dnipropetrovsk and Mykolaiv regions) and outside the risk zone (Volyn, Vinnytsia and Zaporizhzhia). Studies of bromine content in eggs, feed, and water were performed in the laboratory of toxicological monitoring of the National Scientific Center "Institute of Experimental and Clinical Veterinary Medicine" (Kharkiv) using X-ray fluorescence analysis. As a result of the conducted researches, the increase of the bromine content in chicken eggs in the dynamics of 2016 – 2020 was established: the bromine content increased regardless of the region of the poultry farm location. The highest bromine concentration in chicken eggs was found in Kharkiv, Dnipropetrovsk, Mykolaiv, and Zaporizhia regions. Bromine source in poultry products is the excessive intake of bromine in the poultry body with alimentary environmental factors (feed and water). Bromine content in feed for chickens increased in the research dynamics (from 35.1% in the Poltava region to 2.5 times in the Zaporizhzhia region). It exceeded the established EFSA (4.4% of the total) and the average in Ukraine (51.2% of the total number of samples). In addition, the average bromine content in feed from poultry farms of the studied regions of Ukraine correlated with the number of registered and approved bromine-containing pesticides. The average bromine concentration in water sources in the studied regions of Ukraine had no significant differences compared to the beginning of the study but exceeded the maximum allowable concentration by 21.7% in 2016, 34.8% in 2018 and 39.1% in 2020. The maximum bromine concentration was in water sources in Mykolayiv, Kharkiv, and Dnipropetrovsk regions.

Triazoline compounds influence on the meat productivity of turkey carcasses

“…Similar results were obtained for the feeding of triazoline compounds to broiler chickens in the experiments of O. Orobchenko et al (2022), where a positive effect on reducing the time of poultry fattening was found, which is important for industrial meat poultry production. The developmental dynamics of broiler turkeys, which were used in the experiment to study the effect of triazoline compounds on meat productivity, showed that the introduction of GKPF-109 caused a large difference between the weight of different parts of the carcasses.…”

Morphological features of the cuticle of hatching eggs of chickens and turkeys subjected to pre-incubation treatment

“…The quality of eggs used for incubation is the most crucial and essential factor in accurately forecasting the hatchability and viability of offspring and acquiring safe and excellent poultry products (Goliomytis et al, 2015;Melo et al, 2021). It should be noted that the quality of hatching eggs is influenced by an array of biotic and abiotic factors (Nasri et al, 2020;Orobchenko et al, 2022).…”

Toxicological evaluation of feed contaminated with mycotoxins using a luminescent microorganism

“…Obtaining quality livestock products is not possible without scientifically sound, complete feeding of productive animals. The quality and safety of the feed used, and the level of their contamination by abiotic and biotic factors are important (Gosling et al, 2021;Orobchenko et al, 2022).…”
