The analysis of the lower jaws of 265 wild boars, including 143 piglets and 122 yearlings, harvested in Zielonka Game Investigation Centre showed that farrowing took place most often in March (43.3%), February (23.8%), April (17.5%) and January (11.2%). Piglets were also born in May, June and July. The percentages for yearlings were a little different.

The aim of the paper was to evaluate the effect of the birth body weight of the piglets on their productivity and survivability up to the age of 10 weeks. The observations covered the piglets born by 11 sows F1 of Polish Large White × Polish Landrace, inseminated by the semen of the boras (Duroc × Pietrain). The piglets were weighed on 1st, 21st, 35th and 70th day of life and the feed intake (per litter) was controlled. Depending on their birth body weight, the piglets were classifi ed into two groups: light (L) <1.5 kg (n = 52), heavy (H) ≥1.5 kg (n = 60). The mean general body weight of the piglets on 1st, 21st, 35th and 70th day was equal to 1.45, 5.09, 7.70 and 14.18 kg, respectively. In the groups, it was as follows: L – 1.17, 4.58, 6.91 and 13.00 kg; H – 1.70, 5.51, 8.29 and 15.12 kg, respectively (L–H, P ≤ 0.001). The deaths of the piglets in groups L and H amounted to 15.4 and 6.7%, respectively. In the situation of a free access of the progeny to mother’s feed and solid feedstuff, the obtained results indicate that the worse productivity, as expressed by lower feed conversion (by 10.5–16%), slower growth rate (by 12–20%) and lowered survivability (by 8.7 percentage points) of the piglets from groups L vs. group H, were the effect of considerably lower body weight of the newborn piglets as compared to their mean body weight

Wpływ masy ciała prosiąt przy urodzeniu na ich odchów do wieku 10 tygodni. Celem pracy była ocena wpływu masy ciała prosiąt przy urodzeniu na ich produkcyjność i przeżywalność do wieku 10 tygodni. Obserwacjami objęto prosięta urodzone przez 11 loch F1 rasy wielka biała polska × polska biała zwisłoucha inseminowanych nasieniem knurów (duroc × pietrain). Prosięta ważono w 1., 21., 35. i 70. dniu, kontrolowano pobranie paszy (na miot). Prosięta w zależności od masy ciała przy urodzeniu podzielono na grupy: lekkie (L) <1,5 kg (n = 52), ciężkie (H) ≥1,5 kg (n = 60). Średnia masa ciała wszystkich prosiąt w 1., 21., 35., i 70. dniu wyniosła: 1,45; 5,09; 7,70; 14,18 kg, a w grupach odpowiednio: L – 1,17; 4,58; 6,91; 13,00 kg oraz H – 1–70; 5–51; 8–29; 15–12 kg (L–H, P ≤ 0,001). Upadki prosiąt grup L i H wyniosły 15–4 i 6–7%. Przy swobodnym dostępie potomstwa do pokarmu matki i paszy stałej uzyskane wyniki wskazują, że gorsza produkcyjność wyrażona słabszym o 10,5–16% wykorzystaniem paszy, wolniejszym o 12–20% tempem wzrostu oraz obniżoną o 8,7 punktu procentowego przeżywalnością prosiąt z grupy L względem grupy H, były efektem znacząco mniejszej w stosunku do średniej masy ciała nowonarodzonych prosiąt.

Przebadanych zostało 6 modeli gniazd ogrzewanych płytą podłogową, które monitorowane były w ciszy i przy ruchu powietrza o prędkości 0,5 m/s, płynącym prostopadle do ściany frontowej gniazda. Stwierdzono, że przy ruchu powietrza temperatura wewnątrz modeli A, B, i C obniżyła się, a wewnątrz gniazda D wzrosła. Zmiany te były niewielkie (średnio 0,4-1,2K). Przeniesienie wejścia do gniazda ze ściany długiej na krótką dające pogłębienie przestrzeni gniazda i zmniejszenie otworu wejściowego (modele C1 i D1), również spowodowało wzrost temperatury wewnątrz gniazda. Daje to podstawę do stwierdzenia, że konstrukcje pozwalające na swobodny napływ i wypływ powietrza z gniazda powoduje jego wychłodzenie, lecz w mniejszym stopniu niż można by oczekiwać. Natomiast przy konstrukcjach wymuszających krążenie powietrza we wnętrzu gniazda następuje zjawisko odwrotne, czyli wzrost temperatury, a dodatkowo daje się w nich zauważyć wyrównanie jej wartości w strefie przebywania zwierząt.

The influence of air movement in farrowing pen on the air temperature within piglets' creep area was monitored. The creep area was encased with 6 different cover constructions and tested undr the quiet condition and at the 0.5 m/s air flow. Experimental results indicated that the influence of air flow on thermal conditions within covered creep area was unexpectedly small (less than 1.2 K). Comparison of the results obtained under draft movement to results under quiet conditions showed, that the air temperature in the piglets' nest was lower under cover A, B and C, while inside the model D the air temperature was higher. It could be said, that the cover constructions making possible free air movement inside the nest, lowered the temperature. A contrary phenomenon was recorded under the cover forcing the air circulation inside. It lets also notice more even horizontal temperature distribution in zone of animals' sojourn.

The aim of the project was to observe the influence of a high dose of BioPlus 2B on selected parameters and mean weight gain of suckling piglets. The body weight of piglets was controlled and blood samples were taken on days 0, 7, 14, 21, 28 and 35 of the experiment. The red blood cells (RBC) increased gradually in both groups and at the end of the experiment, the number of erythrocytes in the experimental group was significantly higher (P < 0.05) compared with the control group. The level of urea in the control piglets began increasing from the fourth week of life. At the fifth, sampling the urea level in the control group was considerably higher and the difference between groups was significant (P < 0.05). By the week five the mean weight gains differed significantly between the groups (P < 0.05). The final mean weight of experimental piglets was 10.6 kg and the control piglets 9.9 kg.

One of the possibilities for estimating pancreas activity is the estimation of zymogene granule content in pancreatic follicular cells. In the present study, the degree of pancreatic activity wasmeasured in piglets from sows receiving enzymatic stimulating complex throughout pregnancy and during the lactation period. The pancreas was collected for ultrastructural examination from 1-day-old and 21-day-old piglets. The enzyme preparation influenced the ultrastructural structure of the piglet pancreas, but the secretory cells in these animals did not confirm a more intensive course of creation and maturation processes. The accumulation of granules in extra-secretory pancreatic cells was observed, with a large volume of these granules and granular crinophagy observed in older piglets. The findings indicate a slow process of granule release, which may be the result of overproduction, lower requirements for enzymes contained in the granules, or both.

The investigation was carried out on 51 piglets. 11 piglets were used as control animals. The remaining 40 piglets were given (daily, starting from the third day of life) 2 ml of 18-hour Lactobacillus strain culture containing 1 x 108 bacteria isolated from the pig( alimentary tract. Clinical, haematological and biochemical examinations were performed on all animals at the age of 2, 6, 15 and 21 days. One piglet from each of the control and experimental groups and from each respective age group was subjected to euthanasia in order to collect duodenum and jejunum samples to determine the number of colonizing Lactobacillus strains. A decrease in the haemoglobin level, an insignificant fall in the urea level and an insignificant degree of compensated metabolic acidosis were found in the piglets examined. The investigation revealed that an administration of Lactobacillus strains to piglets has a positive influence on the functioning of the alimentary tract, causing no disturbances in the homeostasis of the organism. Compensated metabolic acidosis of an insignificant degree did not have any significant impact on the state of health of the animals under study.

Nonadrenergic noncholinergic (NANC) vasodilator mechanisms may contribute to the maintenance of adult pulmonary and systemic vascular tone. However, their actions in the neonatal circulation have not been studied. We aimed to investigate NANC vasorelaxation in neonatal and 2-week-old piglet pulmonary and mesenteric arteries and to examine the potential role of nitric oxide (NO) in this phenomenon. Responses to electric field stimulation (EFS, 50V, 0.25-32 Hz) were investigated in pulmonary and mesenteric artery rings (external diameter 150-200 µm) precontracted with the thromboxane A2 mimetic U46619, in the presence of guanethidine (10 µM) and atropine (10 µM). Under these conditions, EFS resulted in a frequency dependent relaxation of newborn pulmonary (maximal relaxation of 53±9.1%), mesenteric (68.8.2±7.1%) and 2-wk-old mesenteric (46 6.3%) arteries but this relaxation was significantly reduced (4.5±2.2%) in 2-week-old pulmonary arteries. In neonatal pulmonary arteries, the neurotoxin tetrodotoxin (0.3 µM), the NO synthase inhibitor L-NAME (0.1 mM), and the guanylyl cyclase inhibitor ODQ (10 µM) abolished EFS-induced relaxations, suggesting that NANC relaxation of porcine neonatal pulmonary arteries is mediated by NO, which is probably neuronal in origin. However, The expression in pulmonary arteries of the neuronal NO synthase (nNOS), as determined by Western-blot analysis, increased with postnatal age whereas the expression of the endothelial NOS (eNOS) did not change. In conclusion, NANC relaxation is present in neonatal pulmonary and mesenteric arteries and it is, at least partially, mediated through NO. NANC relaxation of porcine pulmonary and mesenteric arteries decreases with postnatal maturation.

The effect of the use of the emulgator Lysoforte was investigated in the 33 days” experiment on piglets. Piglets weaned at the age of 28 days were divided into two groups - experiment (E) and control (C) - 10 piglets in each. In E group Lysoforte was fed as an additive (1 kg/ton) to the commercial mixture ČOS without growth promoters. The live weight and feed consumption were recorded individually. At the end of the first week of the experiment the piglets” faeces were collected during two days to determine the digestibility of dry matter, nitrogenous substances, fibre, fat,organic matter and ash by means of a calculation of the proportion of ash insoluble in HCl. There was no effect of Lysoforte on the daily gain of piglets (C = 339 g, E = 342 g), but the feed intake per kg live weight gain was found lower (C = 1.899, E = 1.770 kg). The digestibility of all proximate feed components was found higher in E piglets - the inter-group difference for dry and organic matter reached approx. 5%, those for ﬁbre, nitrogenous substances and ash from 9.5 to 13.4 %, and 49% for fat. The economic evaluation proved the return of increased expenses per 1 kg of the feeding mixture by adding Lysoforte from 14.40 to 14.60 CZK/kg. The cost of feed per 1 kg live weight gain was reduced by 5.5% (C = 27.346, E = 25.842 CZK).

W końcu pierwszego tygodnia doświadczenia określono strawność suchej masy, związków azotowych, włókna, tłuszczu i popiołu zawartych w paszy C i E. Nie stwierdzono wpływu dodatku Lysofortu do paszy na przyrosty warchlaków (grupa C - 339, grupa E - 342 g dziennie). W grupie E wystąpiła jednak poprawa wykorzystania paszy (grupa C « 1,90, grupa E - 1,77 kg/kg przyrostu. W gnipie E stwierdzono poprawę strawności wszystkich badanych składników pokarmowych. Koszt I kg przyrostu okazał się w grupie żywionej paszą z Lysofortem (E) niższy o 5,5% w stosunku do grupy kontrolnej (C).
