The article studied the reproductive qualities of sows and the growth of piglets under one-phase and two-phase feeding of suckling piglets. This study aimed to determine the dependence of the intensity of growth and survival of suckling piglets and feed consumption for feeding them using super-pre-starter feed during two-phase feeding of hybrid suckling piglets of Irish origin. In the conditions of the industrial complex, a comparison was made of the use of pre-starter feed traditional for the farm when it was fed to piglets from the seventh to the twenty-first day of life and the super-pre-starter, which was fed from the second to the fourteenth day, with subsequent transfer to the feed traditional for farms with pre-starter fodder. The advantages of the nests of piglets, which were used in the post-sucking period, were two-phase feeding from the second to the fourteenth day with super-pre-starter feed with a gradual transfer from the fourteenth to the eighteenth day of life to feeding with the pre-starter combined feed traditional for the farm and its subsequent use before weaning over analogs with single-phase feeding, which from the seventh to the on the twenty-first day, the traditional pre-starter feed was fed according to the survival of piglets before weaning by 5.7 % and as a result, their number at the time of weaning was 10.3 % greater and with practically the same individual weight of the weaned piglets, by 9.1 % the weight of their litter during this period, in comparison with their analogs, which used single-phase feeding from the seventh to the twenty-first day with traditional pre-starter feed. There was no significant difference in the individual weight of piglets at weaning and the average daily growth of piglets in the weaning period. It has been proven that during two-phase feeding, piglets ate 46.6 kg less of the entire range of feed for suckling piglets, which was 34.5 % less per litter and 49.5 % less per head. The comprehensive index of reproductive qualities of sows was better by 2.3 points or 5.4 % in sows whose nests of piglets were fed in two phases compared to animals whose offspring were fed in one phase.
Feeding in the dry season affects the viability of the offspring and milk in the next lactation. In addition, proper feeding prevents heavy calving, metabolic disorders (paresis, ketosis, delayed litter, etc.), increases fertilization, and improves colostrums quality. The purpose of the study was to investigate the effect of nutrition on nutrition, metabolic disorders, and reproductive function in cows after calving after nutrition of nutriCAB (encapsulated calcium chloride). The effect of feeding NutriCAB (encapsulated calcium chloride) in the period of late dryness on dairy productivity, metabolic disorders and reproductive functions in cows after calving is investigated and the zootechnical and economic efficiency of such feeding is determined. The study was conducted on 44 dry cows. Dry cows received NutriCAB starting at 21 grams per day at 130 grams / head / day. The results of the studies have substantiated the need for late cationic anion-tonegative (DCAB) rations with NutriCAB, which contributes to hotel relief, reduced metabolic abnormalities, improved health and reproductive performance. Late-dry cationic anion-to-negative diet (DCAB) rationing with NutriCAB makes it easier to calve, reduce metabolic abnormalities, improve the health and reproductive function of cows, get faster milk yields and provide stability. The introduction of the NutriCAB product to cows in late dryness significantly lowered the urine pH after 5 days. The use of anionic salts in rations of dry cows at the current price is economically feasible. Mainly by reducing the costs of post-partum metabolic disorders, as well as the positive trends in feed intake, increased animal productivity, reduced length of service, and more efficient conversion of feed into milk.
Formulation of the problem. The internationalization of international economic relations and globalization have necessitated international unification and harmonization of legislation in the field of electronic document management, the purpose of which is to exchange information between participants in relations located in different states. In this regard, it seems impossible to ensure effective legal regulation of these legal relations within one country without taking into account the established approaches in international practice and foreign legislation. The unification of the rules on electronic documents and their use in contractual relations are based on economic and legal reasons. One of these factors was the emergence and development of new means of communication, as a result of which economic relations went beyond the boundaries of individual states and ceased to be tied to a specific national territory. Among the reasons specific to this area, it should be noted the emergence of new ways of certifying the authenticity of documents and new forms of documents, through the exchange of which it is possible to conclude, execute contracts, and perform other legally significant actions for civil and international circulation. The benefits of using new technical means have necessitated the need to establish legal requirements for such use. However, the issuance of special acts at the domestic level will not contribute to the development of international trade, since the law of each state has its own characteristics, due to centuries-old traditions and modern interests of the state in various fields.The state of research of the topic.
