In altricial species, early pre- and neonatal undernutrition interferes with the neuronal organization of several brain structures that have critical time windows for synaptic organization, including the prefrontal cortex. In Golgi-Cox stained tissue the basilar dendritic arbor of pyramidal neurons in the anterior cingulate cortex of early underfed adult lactating dams was evaluated. The anterior cingulate of the rat plays a major role in the execution of sexual, maternal and visual attentional control and other cognitive responses. The effects of neonatal undernutrition on the basilar dendritic tree and perikaryon measurements in layer II/III pyramidal neurons of the anterior cingulate were examined in lactating dams at postpartum days 8 and 12. In the underfed dams the distal portions of the basilar dendrites had fewer branches and a lower dendritic density of dendrites, and neurons had perikarya with reduced perimeter and cross-sectional area. Thus, the neuronal alterations may interfere the plastic synaptic activity and with maternal cognitive performance of rats subjected to early underfeeding. These anatomical alterations of the anterior cingulate may help to understand the disruption of long-term cognitive processes associated with perinatal food restriction.

The aim of the study was histopathological characteristics of mink females showing a tendency to decrease body condition in a perinatal period against a background of selected parameters of antioxidant state. The minks were divided into two groups according to body condition scoring system (BCS). The blood was collected twice: after weaning and at the end of the production cycle. The serum activity of oxidative state enzymes was determined. Anatomic and histopathological examinations were conducted after the production cycle. Samples of the liver, kidneys, small intestine, and ovaries were fixed in 10% buffered formalin and stained with haematoxylin-eosin and Sudan IV. The histopathological examinations revealed hyperaemia of the liver and kidneys, with large content of blood in the capillary and central vessels of obese females. The kidney structure was normal in animals of experimental group. On the other hand, kidneys of control group animals showed degenerative changes in the epithelial cells of the tubules of the excretory part, especially of the proximal tubules. Against the background of the obtained results, it should be stated that lower activities of selected enzymes with anatomical and histopathological changes were obtained in the animals with worse body condition.

The aim of the study was to determine the effect of the perinatal period on redox status indicators in the blood of ewes before and after lambing and during lactation. The study was performed on 12 ewes of the synthetic SCP line. Blood for testing of redox parameters was collected seven times: before pregnancy, 1.5 months and 24 h before lambing, 2 and 24 h after lambing, and in the fourth and eighth weeks of lactation. The following blood indices were determined by spectrophotometry: lipid peroxides, malondialdehyde, superoxide dismutase, catalase, plasma total antioxidant capacity, uric acid, urea, bilirubin, and creatinine. The tests showed that during the perinatal period reactions are generated which lead to oxidative stress. Oxidative stress in pregnant ewes was found to increase during the period before lambing and may persist even up to weeks 4-8 of lactation.

The aim of the study was the determination of IgA, IgM and IgG concentrations in porcine serum and colostrum, in order to evaluate their variations in the perinatal period, as well as to clarify whether there is a correlation between colostrum intake, initial level of immunoglobulins (Ig) in piglet serum and development of their own immunity. The mean IgA, IgM and IgG concentrations in sow serum 10 days before parturition were 1.58, 6.12 and 39.56 mg/ml, respectively. Seven days later only the IgG level was insignificantly lower (34.94 mg/ml, p=0.55), while concentrations of IgA and IgM increased to 2.25 and 7.25 mg/ml, respectively (p=0.23 and 0.62, respectively). The mean initial IgG concentration in colostrum at farrowing was 118.5 mg/ml and differed between sows. The average value of IgA in colostrum at birth was 23.8 mg/ml and decreased to 7.85 mg/ml at 6 hours (h) and to 4.59 mg/ml at 24 h after the onset of farrowing. IgM concentration at birth was 12.1 mg/ml and decreased to 4.23 mg/ml at 24 h postpartum. Positive relationships were found between concentrations of IgM and IgA in serum of piglets at 14 and 56 days of life (r = 0.41 and 0.80, respectively, p≤0.05) as well as for IgG concentration in the piglets serum at 7 days and 56 days of age (r = 0.48, p≤0.05). The above observations suggest that there is a correlation between the level of Ig in piglet serum in the first days of life and improvement of their own immunity.

The course of S. papillosus infection in lambs born by ewes affected with this disease was estimated on the basis of the presence of parasitic eggs in faeces. The examinations were started 2 weeks prior to the expected parturition and were continued in lambs and their mothers at 2-week intervals until the lambs were 100 days old. It was demonstrated that 60% or the lambs had been infected with S. papillosus by the third week of their life. In their mothers, increased infection extensity was found at the perinatal period.

Badaniem objęto 25 krów rasy czarno-białej, w wieku 4-8 lat, o wysokiej wydajności mlecznej (średnia wydajność mleczna krów wynosiła 5123). W dziennej dawce żywieniowej krowy otrzymywały 30 kg kiszonki z kukurydzy, 20 kg buraków, 3 kg siana oraz paszę treściwą do 2 kg dziennie. Wszystkie krowy były badane klinicznie, a materiał - krew i mocz - od nich pobrany poddano analizom laboratoryjnym. Badania prowadzono czterokrotnie: 2 tygodnie przed porodem, tydzień, miesiąc i 2 miesiące po porodzie. Jednorazowo przeprowadzono badania koproskopowe i badanie moczu. W zakresie badań hematologicznych oznaczano Ht, Hb, Erys, w zakresie badań biochemicznych - poziom białka całkowitego i jego frakcji, aktywność AspAT, GGTP, AP, ChE, stężenie glukozy, WKT i związków ketonowych. Uzyskane wyniki wskazują na istnienie zaburzeń u badanych krów, polegających na zachwianiu gospodarki energetycznej. Oznaczane wskaźniki okazały się wystarczające do ich diagnozowania. Powyższe badania dały podstawę do prowadzenia postępowania zapobiegawczego i terapeutycznego.

Celem pracy było zbadanie możliwości sterowania przebiegiem okresu okołoporodowego u krów z zastosowaniem lewamizolu jako elementu postępowania metafilaktycznego. W badaniach zastosowano własną modyfikację metafilaktyki, której istotą jest dążenie do pobudzenia i normalizacji mechanizmów obronnych zwierzęcia, przez zastosowanie immunostymulacji. Stosowanie lewamizolu jest zgodne z zasadami zmodyfikowanej metafilaktyki, przy jednoczesnym badaniu wybranych wskaźników nieswoistej odporności komórkowej. W niniejszych badaniach był to test spontanicznej migracji leukocytów (SML) . Trzykrotne podanie lewamizolu (2.5 mg/kg m.c., co 7 dni im.) u krów klinicznie zdrowych, u których stwierdzono obniżoną wartość wskaźnika SML, na 3 tyg. przed porodem, wpłynęło na spadek odsetka zatrzymania błon płodowych oraz stanów zapalnych błony śluzowej macicy, a także na poprawę wskaźników płodności w stosunku do zwierząt kontrolnych (z obniżoną wartością SML, bez stosowania lewamizolu). Jednocześnie zwierzęta poddane immunostymulacji wykazywały wyższy odsetek zatrzymania błon płodowych, endometritis oraz gorsze wskaźniki płodności niż krowy z normalną wartością SML badaną przed porodem.
