Szczury dwu kolejnych pokoleń, karmione paszą standardową zawierającą 10% popiołów węglowych, poddano badaniu masy ciała w pierwszej dobie życia i co tydzień przez 12-15 tygodni. Opracowane statystycznie wyniki wykazały w pierwszych 6 tyg. życia istotnie wyższą masę ciała szczurów pozostających na diecie z dodatkiem popiołów w porównaniu z grupą szczurów kontrolnych (pasza standardowa). W dalszych tygodniach życia nie stwierdzono wpływu paszy na masę ciała badanych zwierząt.

Background. Caloric restriction (CR) leads to decrease metabolic intensity, which results in a reduction of oxygen consumption and the amount of free radicals. This can affect the function of the liver. Studies show that caloric restriction does not alter or significantly increase the enzyme activity associated with gluconeogenesis, but the effect was different according to the age of the model animals. Objective. The aim of the study was to determine the effect of caloric restriction on liver function in young and old ApoE/ LDLr-/- mice. Material and methods. Dietary experiments were performed on 2 and 5 month old male ApoE/LDLr-/- mice. Animals were divided into 3 experimental groups (n=6) and fed AIN’93G diet for 8 and 5 weeks, respectively. Control animals were fed ad libitum (AL) and housed in a colony cages. These animals were checked for dietary intake. The second group were also fed ad libitum but the animals were kept individually in cages (stress AL- sAL). Similarly to sAL group, the animals from the CR group were kept individually but received a 30% less diet compared to AL group. At the end of the experiment animals were euthanized and the blood, liver and adipose tissue have been collected. Alanine aminotransferase (ALT) as well as aspartate aminotransferase (AST) were measured in plasma. Fatty acid profile was evaluated (relative %) in adipose tissue (GC-MS). Liver’s stetosis was assessed. Results were analyzed statistically (ANOVA, STATISTICA v.10.0). Results. CR ApoE/LDLr-/- mice showed significantly lower body weight compared to animals, both AL and sAL. There were no significant differences between ALT and AST in both younger and older animals. However, negative tendencies were more pronounced in younger animals. In young animals CR significantly increased liver weight compared to AL (4.14 vs 3.73g/100g). In adipose tissue fatty acid profile differed in CR mice compared to control in young animals. Conclusions. Caloric restriction did not affect liver enzymes in mice. Caloric restriction showed similar but not identical metabolic activity in young and old mice.

Carbaryl, propoksur, and thiuram were administered for 14 days, by a stomach tube, at dosing level corresponding to 5% LD50 , to male Wistar rats four weeks old and fed a diet enriched with vitamin B6 (200 µg/day). Active and passive leucine transport in rat intestine was studies using liquid scintillation method according to Patrick and Papworth, modified by the authors. No disorder of leucine transport was observed in animals exposed to carbaryl and propoksur, and fed a diet enriched with vitamin B6. No disturbances were also noted in subject exposed to thiuram, except that Jm constans was increased by about 170% when compared with the control, and the affinity was decreased (rise of Kt constant by 320%). However, it seems that the diet enriched with vitamin B6, may protect amino acids homeostasis in animals exposed to some xenobiotics.

Influence of application of (1,3)-(1,6)-β-D-glucans and mannans on production results of sows and piglets. The aim of the study was the assessment the production results and health status of sows and their offspring modulated by supplementation of (1,3)-(1,6)-β-D-glucans and mannans. The experiment was carried out in farrowing and nursing sector.It was performed using crossbreed (Polish Large White × Polish Landrace) pigs. The additive of (1,3)-(1,6)-β-D-glucans (G) or (1,3)-(1,6)-β-D-glucans and mannans (GM) was introduced to the feed for sows from the 85th day of gestation and for their offspring from the 22nd (after weaning) to the 90th (moving to the fattening sector) day of life. Production results were estimated basis on: changes of body weight of sows during lactation and their offspring during the experimental time, average feed intake, feed conversion ratio, mortality. To estimate health status blood samples from sows and their offspring were taken to determine the total protein level and its fraction in serum. The obtained results indicate that the additive of G or GM to lactation sows and weaned piglets can usefully influence on catabolism process in sows, growth performance and health status in piglets.

Alimentary rations under test were found to be rich in fat. Fat energy proportional portion exceeded, as a rule, the recommended value by about 30%. At the same time, acidic composition of fat under test was wide of the optimal one. Predominant group was saturated and monounsaturated acids (occurring in similar amounts), however, polyunsaturated acids content amounted to about 11 % of total fatty acids sum. Energy proportional portion from essential fatty acids, in a whole day's rations, was found to be higher than necessary minimum (3%); on the other hand, it did not cover the recommended standard for subjects advanced in years (4%). Value P:S was noted to correspond with an average european diet. Portion of acids with proaggregative properties was higher than hypercholesteremic acids content.

Effect of liquid acidifiers on rearing performance of suckling piglets.Crossbred piglets from 36 litters (12 litters each in control group C and in experimental groups E1 and E2) were investigated. From birth to weaning at 28 days of age, piglets from group E1 received drinking water with a 2% solution of lactic, formic and orthophosphoric acids, and those from group E2 a 0.05% solution of Baracid P, which contained phosphoric, citric, lactic, formic and tartaric acids. No acidifier was used in group C. The piglets were monitored for body weight, mortality, and the incidence and duration of diarrhea. Production parameters were average in all the groups. Daily weight gains from 1 to 28 days of age were comparable in the groups (P >0.05). The additives increased piglet survival (by 1.0 percentage point in group E1 vs C and by 1.8 percentage point in group E2 vs C) and decreased the number of days with diarrhea in experimental compared to control piglets. The differences in daily gains between the groups were statistically not significant, but the improved health and higher survival of piglets in the experimental groups compared to the control group indicate the appropriateness of using acidifiers in rearing of young pigs.
