“…In addition to suboptimal nutrition, the heat stress, the high stocking density, and the high NH3 induce inflammation, oxidative damage to cells, and reduce gut integrity, weakening the immune system of the animals making them more susceptible to infection and less efficient [49,[52][53][54]. NH3 irritates the conjunctiva causing conjunctivitis [55], irritates the mucosal layer of the respiratory system and depresses ciliary activity and mucus flow [56] and damaging trachea [57] which predisposing animals to infection.…”

This study aimed to assess the feasibility of employing audio and vision technologies as an integrated monitoring system to monitor the health and behavior of pigs under different environmental conditions and to associate these factors. A total of 81 growing pigs ((Landrace x Largewhite) x Duroc) with distinct weight categories (10.47 ± 2.57 kg and 28.81 ± 5.03 kg) were distributed into two distinct housing conditions: Control (characterized by low NH3 levels and low stocking density) and Treatment (marked by elevated NH3 levels and varying stocking densities). Each house was installed with a SoundTalks monitor for automated daily evaluation of respiratory health status (ReHS), and a camera with a microphone to facilitate manual tracking of respiratory symptoms and behavioral patterns. Results showed that the Treatment group encountered significantly high room temperature, NH3 concentration, and carbon dioxide levels, resulting in compromised growth performance—a phenomenon further exacerbated in high stocking density conditions. Pigs within the treatment exhibited increases (p &lt; 0.05) in lateral and total lying behaviors, and incidences of ear and tail injuries, increases screaming frequency, conjunctivitis incidences, coughing frequency, elevated respiration rates, and a decrease in ReHS. The environmental conditions affect the behavior and health of the pigs. Moreover, the behavioral patterns of the pigs are associated with their health conditions. The SoundTalks system did not trigger any warnings during the experimental period. Nevertheless, trend analysis indicated a significant reduction in respiratory health in the treatment. In conclusion, this study underscores the efficacy of merging audio and visual technologies to holistically monitor pig health and behavior, enabling enhanced management strategies. Findings emphasize that monitoring the ReHS trend serves as a pivotal marker for identifying respiratory health problems, complementing the system's innate alarm functions.

The article considers the issues of changing the variability of protein metabolism in blood serum, namely indicators. Purebred Poltava meat breed main boars of different genotypes were studied: group I (control) – individuals obtained without the use of introductory crossing, group II (experimental) – individuals obtained by introductory crossing with the Finnish Landrace breed, group III (experimental) – individuals obtained by introductory crossing with the Early-maturing meat breed. In boars of all these examined groups, the obtained average values of protein metabolism indicators did not differ significantly from each other, however, some features of the indicators depending on the genotype were revealed. In boars obtained using various variants of introductory crossing (experimental groups), the average value of total protein in blood serum exceeded the limits of reference values. The introduction of the Finnish Landrace blood to the Poltava meat breed boars in order to improve meat qualities leads to the formation of a genetically determined higher level of biosynthetic processes in the body, manifested in the stabilization of protein anabolism in the body and an increase in the intensity of its catabolism processes. The introduction of the Early-maturing meat breed to the Poltava meat breed boars in order to improve adaptive qualities leads to stabilization of protein metabolism indicators characterizing both anabolism and catabolism.
