“…In production, when evaluating eggs, the predominant indicator is the shell strength, since it is from this indicator that the level of damage and the percentage of non-standard eggs depend. The poor quality of the egg shell leads to a decrease in its grade and food safety [19,20]. The shell strength primarily depends on its structure and the organization model of calcium minerals (i.e., the size of the crystals and the way they combine), which form the different layers of the egg shell.…”

Currently, intensive industrial use of poultry facilities and a large concentration of livestock negatively affect the bacterial background and, consequently, the microflora of the bird body. Due to the settlement of opportunistic and pathogenic microflora in the microbiocenosis of the chicken gastrointestinal tract, after 10-11 months of productivity, laying hens either weaken in egg production or in egg quality. The article describes the results of the absorption of calcium and phosphorus macronutrients by the body of laying hens when phytobiotics are introduced into the feed. According to the research results, it was determined that in birds receiving phytopreparations, the absorption of calcium and phosphorus increased by 10.13 and 10.31% compared with the control, and the content of these elements in the tibia increased by 2.30 and 1.54%, respectively, on average during the experiment. During the studies, the egg weight of the experimental chickens exceeded the control by 1.03-5.26%, while the shell strength was higher by 0.72-1.73%.

One of the indicators of behavioral activity in response to the impact of environmental factors is acoustic signaling as an element of sound communication of birds. The purpose of the research work was to study acoustic signaling of turkeys of Highbrid Converter cross, grown in conditions of poultry breeding enterprise of Tyumen region. The object of research were turkeys of different groups of different age (1, 12, 41, 56, 69 days) and sex. Loudness of sounds issued by the bird was measured by a noise meter, with fixation of maximum, minimum and average values of sound loudness. Audiometry was carried out in the morning and evening. 76 audiograms were recorded. In the course of background research it was noticed that turkeys constantly make sounds characteristic for the species, communicating among themselves birds do not stop shouting at night, and the noisiest are males. It was found that the average maximum values of loudness level of signals of birds in groups not divided by sex, in 41-day-old birds (81.3 dB) in the evening and in day-old chicks (71.6 dB) in the morning. In 41-day-old birds, the loudness level of acoustic signaling increases (by 5.2 dB) toward evening, and in dayold birds, loudness is 5.1 dB lower in the evening than in the morning. The amplitude of loudness increase has a sharp character. At the same time, the signal volume of day-old chicks in the morning has maximum values (82.0 dB), which are also found in the groups of older chicks (69 days). However, in the evening, the maximum values of day-old chicks' buzzer loudness decrease by 11.5 dB. In groups of chicks separated by sex at 56 days of age, the acoustic signals of males are louder (by 1.2 dB), both in the morning and in the evening (by 1.3 dB). It was also found that the loudness level in both the group of males (by 3.8 dB) and females (by 3.7 dB) increased towards evening. In the group of 69 day-old turkeys, female signals were 1 dB louder than male signals in the evening. Maximum loudness values were recorded in the male group (85.5 dB, 86.4 dB, 87.4 dB).

“…Nevertheless, to achieve such a symbiotic coexistence of the microbiota, certain conditions must be met: the exclusion of low-quality feed contaminated with mycotoxins in recipes, the use of reasonable diets and their quantity, the absence of reduced herd immunity due to diseases, the absence of stress factors as a result of gross violations of the housing conditions. When at least one of the above factors occurs, conditionally pathogenic and pathogenic microflora gain a competitive advantage and exhibit a pronounced negative effect [2][3][4][5].…”

The article describes the composition of the microflora of caecum in laying hens when introducing feed additives with phytobiotic effect “Activo” and “Activo Liquid” into the diet used at the enterprise. Microbiological studies indicated a lower content (at 24 weeks of age) and absence (at 32 weeks of age) of opportunistic microflora in the caeca of experimental birds in the form of Staphylococcus Saprophyticus; absence of Streptococcus haemolyticus B of serogroup G; a decrease in the level of fungal flora Candida sp. and the absence of hemolytic E. coli (Escherichia coli haemolytic) in all study periods. The noted positive effects contributed to an increase in productive indicators in chickens.
