“…Умови утримання птиці, при яких виникають стреси, призводять до утворення вільних радикалів і розвитку окисного стресу в тканинах і органах, що викликає пошкодження клітинних мембран і порушення ряду фізіологічних процесів, у тому числі зниження імунітету (Vasylieva et al, 2012).…”

This research publication highlights current data on the rational use of feed protein by pheasants, which is related to the physiological needs of chicks in this essential means of nutrition. A thorough analysis of feed used in feeding pheasants at the current stage of development of pheasant breeding was carried out. It has been established that cereals have the most significant distribution. Brief information is provided on various factors affecting the composition, quality, nutritional value, and beneficial effects of the main types of grain feed obtained from different fields for pheasants. These include the technology of growing fodder crops, the composition of the soil, applied fertilizers, the type of crop, the conditions of harvesting and storage of plant products (storage period, processing and heat treatment of raw materials), etc. Features of keeping, feeding, and appropriate care of adult birds are also given. The practical advice of this publication on the specifics of feeding, exceptional care, and technology of raising young animals was considered. Brief information is provided on the general features of the rational and practical use of various protein feeds of plant origin in feeding pheasants – grains of cereal crops: corn, wheat, barley, oats, processed products of oil crops – soybeans, sunflowers, and livestock products, such as meat and eggs. In particular, the peculiarities of providing chicks with exchangeable energy and protein are described as essential indicators of the viability of the young. The practical breeding of pheasants is impossible without the correct use of protein and energy feed. It has been established that providing chicks with sufficient feed, particularly protein, is necessary for the modern technology of successful, promising, engaging, and useful pheasant farming. Suppose the conditions of keeping, care, and feeding of pheasants are violated. In that case, the incidence of disease (especially of young ones) and the survival of chicks increases, negatively affecting the efficiency of the new branch of pheasant farming. In such conditions, stress factors of the external environment, new fodder, internal factors with a sharp change in the environment, feeding, poor microclimate conditions, etc., are the factors that lead to the occurrence of diseases. Therefore, optimizing and creating comfortable conditions for keeping pheasants is an urgent task at the current stage of developing a rather exciting and rich in its subtlety industry – pheasant farming.

“…Experimental spectra of liquid n-octanol and deuterated n-octanol are presented in Figure 2. All of the spectral regions have been assigned to specific vibrations using the literature data [16,17,[98][99][100][101]. The νOH vibrations have been assigned to very wide, medium intensity band at ca.…”

“…It is not only used as a food additive [7], but it was also investigated as a potential anti-tremor drug [14,15]. It has already been studied via IR spectroscopy in liquid and solid states [16,17], and bears a great similarity (with regard to spectral composition) to n-decanol, studied previously via nonlinear dielectric effect (NDE) and IR spectroscopy [18][19][20]. We have employed experimental and diverse theoretical approaches to investigate n-octanol molecular features with special attention paid to the intermolecular hydrogen bond.…”

Intermolecular Interactions and Spectroscopic Signatures of the Hydrogen-Bonded System—n-Octanol in Experimental and Theoretical Studies

et al. 2022

n-Octanol is the object of experimental and theoretical study of spectroscopic signatures and intermolecular interactions. The FTIR measurements were carried out at 293 K for n-octanol and its deuterated form. Special attention was paid to the vibrational features associated with the O-H stretching and the isotope effect. Density Functional Theory (DFT) in its classical formulations was applied to develop static models describing intermolecular hydrogen bond (HB) and isotope effect in the gas phase and using solvent reaction field reproduced by Polarizable Continuum Model (PCM). The Atoms in Molecules (AIM) theory enabled electronic structure and molecular topology study. The Symmetry-Adapted Perturbation Theory (SAPT) was used for energy decomposition in the dimers of n-octanol. Finally, time-evolution methods, namely classical molecular dynamics (MD) and Car-Parrinello Molecular Dynamics (CPMD) were employed to shed light onto dynamical nature of liquid n-octanol with emphasis put on metric and vibrational features. As a reference, CPMD gas phase results were applied. Nuclear quantum effects were included using Path Integral Molecular Dynamics (PIMD) and a posteriori method by solving vibrational Schrödinger equation. The latter applied procedure allowed to study the deuterium isotope effect.
