“…З початку 1990-х років, головною метою в свинарстві стало підвищення рівня багатоплідності свиноматок для максимізації кількості отриманих поросят як при народженні, так і при відлученні на одну свиноматку за рік (Biermann et al, 2014;Kramarenko et al, 2018). Таким чином, поліпшення репродуктивних ознак свиноматок є ключовим фактором, що визначає ефективність технологічного циклу відтворення свиней і рентабельність виробництва свинини.…”

The main aim of this paper was to estimate the piglet stillbirth incidence distribution in the Large White (LW) sows. The population used for the present study is from a pig farm managed by the Limited Liability Company (LLC) “Tavriys’ki svyni” located in Skadovsky district (Kherson region, Ukraine). The experimental materials used for this study consisted of 100 inds. of productive parent sows of the Large White breed. The estimation of reproductive performance was conducted for each animal included in this study. The total number of piglets born (TNB), number of stillborn piglets (NSB) and frequency of stillborn piglets (FSB) per litter were monitored in the first eight parities in the period of eleven years (2007–2017). The 800 farrowings averaged 11.3 piglets per litter. Of the 9037 piglets born, 7895 were live born and 1142 were stillborn. Stillborn pigs were observed in 63.3 ± 1.7 % of the litters and the pig stillbirth incidence was 12.6 ± 0.4 %. The percentage of pigs born dead in total pigs born, obtained in this study is within the range of rates (5 to 15 %) reported for commercial pig farms in other countries. The frequencies of litters with 1, 2, 3, 4 and 5 or more stillborn piglets were 27.1, 14.8, 10.6, 5.8 and 5.0 %, respectively. The frequency of litters with at least one stillborn piglet varied from 44 % (2nd parity) to 76 % (6th parity). Significant factor in the analysis for frequency of litters with at least one stillborn piglet was parity number in sow (Chi-squared test: χ2 = 51.35; df = 7; P < 0.001). This frequency increased as parity number in sow increased (Pearson correlation coefficient: r = 0.929; P < 0.01). We noted that the piglet stillbirth incidence in the LW sow’s litter took place already during the first farrowing for almost half of the sows (46%). In general, this distribution is well approximated by the exponential model equation (y = 73.567*exp(-0.551x); R2 = 97.09 %). The LW sows with stillborn piglets in four out of eight farrowings were the most reported. The value of the entropy of the traits NSB and FSB varied significantly among sows of different parities (Chi-squared test: in both cases P < 0.001). At the same time, a significant increase in the entropy estimates for both traits from the 1st parity to the 8th parity was noted (Spearman's rank correlation: P < 0.001…0.002).

“…Дослідженнями вітчизняних та зарубіжних вчених встановлено, що на економічну ефективність галузі свинарства поряд з показниками відтворювальної здатності свиноматок та кнурів-плідників (Lugovyi, 2005;Tserenyuk et al, 2010;Hunchak et al, 2018;Kramarenko et al, 2018;2019) суттєво впливає рівень відгодівельних та м'ясних якостей молодняку свиней (Balatskyi, 2015;Berezovskyi et al, 2016;Nechmilov, 2018;Nechmilov & Povod, 2018). Для поліпшення зазначених груп ознак в селекційних програмах передбачається використання високопродуктивних тварин вітчизняної селекції, а також зарубіжного походження (Grishina, & Fesenko, 2015).…”

The results of studies of fattening and meat qualities of young pigs of different origin and intensity of formation in early ontogenesis are presented. The economic efficiency of the results of the studies is calculated. The study was conducted under the conditions of pedigree reproducer for breeding pigs of the large white breed of LTD “Druzhba-Kaznacheevka” of Dnipropetrovsk region. The object of study was young pigs of English and Hungarian origin, as well animals of varying intensity of formation in early ontogenesis. Estimation of young pigs by absolute and integrated indicators of fattening and meat qualities was carried out taking into account the following quantitative characteristics: average daily weight gain for the period of control fattening, kg, age of reaching live weight of 100 kg, days, thickness of the lard at the level of 6–7 thorax , mm, length of cooled carcass, cm, length of bacon half carcass, cm, index “intensity of formation” (∆t), selection index (SI) and “T-factor”. The economic efficiency of the results of the research was calculated according to the indicator "average daily increase of live weight during the period of control fattening, kg". The analysis of the results of the research shows that the young pigs of the large white breed of the control herd by the age of reaching the live weight of 100 kg were outweighed by the minimum requirements of the Instruction for pig testing by 9.78%, by the thickness of the lard at the level of 6–7 thoracic vertebrae – by 30.33% and by length of the cooled carcass – by 3.52%. Taking into account the class of origin and index “intensity of formation, points” (∆t), the difference between the groups by age of reaching live weight of 100 kg, the thickness of the pelvis at the level of 6–7 thoracic vertebrae and the length of the cooled carcass ranges from 2.24 to 8.03%. It was found that in terms of the main indicators of fattening and meat quality, the young pigs of the large white breed of Hungarian breeding are more consolidated (К1 = 0.085–0.344, К2 = 0.086–0.338). The maximum increment of additional production (average daily weight gain during the control fattening period, kg) was obtained from young pigs of large white breed of English origin (2.39%) and animals with index ∆t at the level of 0.619–0.748 points (1.38%). To evaluate the animals of the main herd (brood boars, sows) according to the fattening and meat characteristics of their offspring, we suggest the use of SI and T-factor breeding indices.

“…Повноцінна годівля поросят-сисунів у більшості господарств України забезпечується передстартерними комбікормами імпортного виробництва, що призводить до підвищення собівартості свинини (Todoriuk et al, 2018;Kramarenko et al, 2018). Крім того, традиційними джерелами мікроелементів у цих комбікормах є мінеральні солі у вигляді сульфатних і хлоридних сполук, біодоступність яких становить 12-35%, що призводить до забруднення навколишнього середовища важкими металами, а кристалізована вода, яка міститься у молекулах сульфатів у складі преміксів, руйнує вітаміни та інші біологічно активні речовини (Kokorev et al, 1994;Bitiutskyi, 2007).…”

In the complete feeding of animals, including pigs, an important role is given to mineral elements, because they take an active part in the metabolism, provide normal conditions for the work of all internal organs, muscles and nervous system. Mineral elements are used by the body of animals as a structural material, they participate in the enzymatic processes of digestion, absorption, synthesis, decomposition, as well as the allocation of metabolic products from the body. Minerals have a positive effect on the activity of enzymes, hormones, vitamins, stabilize acid-alkaline balance and osmotic pressure. They affect the function of hematopoiesis, endocrine glands, protective reactions of the organism, microflora of the digestive tract, participate in protein biosynthesis, strengthen the permeability of cell membranes, etc. The absence or lack of individual mineral elements, as well as the violation of their ratio leads to a reduction in the efficiency of nutrient utilization in the diet and, consequently, to reduce the productivity of animals. Mineral substances account for 4–5% of the body weight of animals, of which 99.6% are on macro-elements, and 0.4% of trace elements. The main source of mineral elements for animals is feed. However, the mineral composition of the latter depends on the biogeochemical zone, type of soils, climatic conditions, plant species, agrochemical measures, collection, storage, preparation for feeding and other factors. When using copper in the form of chelates, a high coefficient of its assimilation is established. In blood, the serum iron content of iron increased and this contributed to a decrease in total and latent iron binding capacity of serum. Copper chelates more intensively stimulate protein synthesizing function, which manifests itself by increasing the content of total protein, albumin and reducing the amount of globulins. Application of micronutrients and their chelate compounds and other biologically active substances has its advantages, the level of assimilation of heavy metals, radionuclides from contaminated feeds and water is reduced, chelate complexes of trace elements easily penetrate through cell membranes, allowing to carry out purposeful influence on exchange substances and energy and to correct the deficit of TE in the relevant biogeochemical zones.
