    Opis:
    Meatquality of fattening pigs born from sows fed different diets during early pregnancy. The aim of the study was to determine the pork quality of fattening pigs (Polish Landrace ´Polish Large White ´Duroc) originated from sows fed during early pregnancy (41 to 70 days) with diets differing in quantity and quality (LD1 vs LK sows – 130% of recommendations, LD2 sows – energy supplement). Thirty-six weaners from LK, LD1 and LD2 sows were selected for fattening and assigned to groups K, D1 and D2 (12 animals per group). Fatteners were fed in 3 phases and kept under standardized environmental conditions (individual pens, constant access to water). Better growth rate in the offspring was obtained as a result of temporarily more intense feeding of pregnant sows with increased daily rations. Modification of the sow diets had no appreciable effect on the slaughter traits of the fatteners postmortem, which shows that there are no contraindications for temporary changes in the feeding of pregnant sows. Good and uniform meatiness of the fatteners in the control and experimental groups was obtained. Chemical composition and physical characteristics of the meat were similar among the groups and the meat was of good quality. Statistically significant differences between the groups were found for several traits: crude ash content, a* colour value, and the proportion of C17:1 and C18:2 n-6 acids.
    Jakość mięsa tuczników pochodzących od loch żywionych odmiennie w ciąży niskiej. Celem pracy było określenie jakości wieprzowiny pozyskanej od tuczników (pbz x wbp x duroc), których matki w okresie ciąży niskiej żywiono okresowo, od 41. do 70. dnia jej trwania paszą, której ilość lub jakość zróżnicowano (lochy LD1 vs LK - dawka większa o 30% w stosunku do norm, lochy LD2 - dodatek energetyczny). Do tuczu wybrano 36 warchlaków od loch LK, LD1, LD2 i przydzielono do grup K, D1, D2 po 12 sztuk. Tuczniki żywiono systemem 3. fazowym i utrzymywano w ujednoliconych warunkach środowiska (kojce pojedyncze, stały dostęp do wody). W efekcie zastosowanego okresowo intensywniejszego żywienia loch prośnych poprzez zwiększenie dziennej dawki paszy uzyskano u potomstwa lepsze tempo wzrostu. Modyfikacje żywienia matek nie miały znaczącego wpływu na cechy rzeźne tuczników określone poubojowo, co wskazuje na brak przeciwskazań do okresowych zmian żywienia loch prośnych. Uzyskano dobrą, wyrównaną w grupach kontrolnej i doświadczalnych mięsność tuczników. Skład chemiczny mięsa i jego cechy fizyczne były na zbliżonym poziomie w grupach, mięso było dobrej jakości. Różnice istotne statystycznie między grupami potwierdzono dla nielicznych cech: zawartości popiołu surowego, wartości a* barwy oraz udziału kwasów C17:1 i C18:2 n6.

    Opis:
    In gilts, the period of early pregnancy occurring from the time of fertilization to the beginning of implantation is sensitive to any environmental disruptions, including an unbalanced diet of a future mother. Previously, we found that due to the undernutrition in gilts during this period, the endocrine intrauterine microenvironment and DNA methylation in the uterus have been changed. These distortions may diminish the success of pregnancy. In this study we focused on the influence of a restricted diet used in gilts during the first days of pregnancy on their biochemical and haematological parameters in peripheral blood. The applied restrictive diet vs. normal diet covered only 70% of the nutritional demands of early pregnant gilts. Normal (n = 4 gilts) or restrictive (n = 5 gilts) diets were used from the day of the first signs of the estrus until day 9 of pregnancy and biochemical and haematological parameters in blood plasma were determined during peri-implantation period, e.g. on days 15 to16 of pregnancy. In restrictive vs. normal fed gilts significantly lower plasma phosphorus, calcium and total cholesterol as well as the tendency to increasing concentrations of triglicerydes and asparate aminotranserase were found. Haematological parameters did not differ between the studied gilts. Thus, it seems that the availability of nutritional factors became suboptimal in restrictively fed early pregnant gilts. Even short-lasting undernutrition of females during the peri-conceptional period may cause a disruption of biochemical homeostasis during the peri-implantation period and probably affect the success of pregnancy.

    Opis:
    The contractile effects of PGF₂α (3 × 10⁻⁶ to 10⁻⁴ M) and PGE₂ (10⁻⁷ to 10⁻⁵ M) were examined on isolated branches of ovarian artery (OA) and extramyometrial branches of uterine artery (UA) collected from pigs in the luteal (day 10-12) and follicular phase (day 17-20) of the estrous cycle, and during early pregnancy (day 10-12). Strong contraction was demonstrated in both arteries during all investigated periods in response to PGF2α, which was significantly higher (P < 0.01) than to PGE₂, being negligible in the follicular phase. In UA, the effective dose of PGF₂α (ED50) amounted 7.9 × 10⁻⁶ M and 6.3 × 10⁻⁶ M in the luteal and follicular phase, and 5.0 × 10⁻⁶ M in early pregnancy. ED50 for PGE₂ reached 5.0 × 10⁻⁷ M in the luteal phase, and 4.1 × 10⁻⁷ M in early pregnancy. For both prostaglandins, the contraction was much stronger (P < 0.01) in OA than in UA branches. In OA, the ED50 for PGF₂α was 1.2 × 10⁻⁵ M in the luteal phase and was significantly higher (P < 0.05) than in the follicular phase (3.1 × 10⁻⁶ M) and early pregnancy (2.7 × 10⁻⁶ M). ED50 for PGE2 amounted 7.3 × 10⁻⁷ M in the luteal phase and 1.7 × 10⁻⁷ M in early pregnancy. Studies showed the influence of the estrous cycle and early pregnancy on OA branches sensitivity to the contractile effect of PGF₂α and the lack of this effect on UA branches, and the influence of the estrous cycle on UA and OA branch contraction in response to PGE2.
