It was found that under conditions of hyperthermia, morphofunctional changes develop in the interrenal part of the adrenal glands, indicating an increase in the functional activity of the gland. The study of ducks on the 5th day of hyperthermia revealed loosening and thickening of the adrenal gland capsule compared to the control. Significant hemodynamic disorders were noted: the phenomena of stasis and erythrocyte sludge in sharply expanded blood capillaries of the adrenal glands. It was found that on the 10th day of hyperthermia, hemodynamic disorders are progressive: the phenomena of sludge and red blood cell stasis are less pronounced, but parenchymal edema and a sharp expansion of sinusoid capillaries persist. Changes in interrenal cells (their high prismatic shape, cytoplasmic vacuolization, apical granularity) are also determined to characterize the high secretory activity of endocrinocytes. The found changes indicate the development of a stress reaction.
The article analyzes the organismal status that determines the adaptive potential of newborn calves to the conditions of technogenic anthropobiocenosis. A complex of zootechnical, clinical, hematological, morphological and statistical methods of research was used. Structural and functional changes in the fetal parts of the placentas of cows arise as a result of the aggressive impact on the mother's body of modern ecosystem conditions and determine the peculiarities of the body status of newborn calves. Determining the adaptive capabilities of one-day-old calves, including the morphology of their fetal part of the placenta, is of great importance not only for correcting the technology of growing and feeding, but also for carrying out preventive measures against infectious diseases. To create a healthy dairy herd of cows with a high degree of realization of the genetic capacities of productivity, we recommend using the developed criteria for assessing the body status of newborn calves. Keywords. Аdaptive potential, newborn calves, anthropobiocenosis, organismic status, fetal parts of the placenta.
The article analyzes the postembryonic organogenesis of the ovaries of Texas quail when using biologically active substances. A set of morphological techniques is used. It was found that the use of probiotic in combination with succinic acid to Texas quail at the age of 5-45 days caused intensive growth and development of their ovaries. Probiotic preparation "Sporovit" and succinic acid do not cause pathological changes in the micromorphological structure of the reproduction organs of quails.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
