Żółw stepowy (Testudo horsfieldii) jest jednym z najczęściej utrzymywanych w hodowlach amatorskich żółwi lądowych. Wiąże się z tym mylne przekonanie o niewielkich wymaganiach środowiskowych i żywieniowych tego zwierzęcia. Celem doświadczenia było określenie preferencji pokarmowych dojrzałych płciowo żółwi stepowych utrzymywanych w warunkach terraryjnych. Postawiono hipotezę badawczą, iż żółw stepowy odznacza się wybiór-czością określonego pokarmu. Doświadczenie według modelu wolnego wyboru trwało 6 tygodni W tym okresie podawano żółwiom trzy grupy łatwo dostępnych i zalecanych literaturowo dla gadów komponentów paszowych: owoce, warzywa oraz rośliny zielne – każdą z nich przez czas 2 tygodni. W eksperymencie użyto ośmiu dorosłych, zdrowych klinicznie i zaaklimatyzowanych żółwi stepowych. Ich preferencje pokarmowe określono na podstawie ilości i składu gatunkowego niewyjadów. Komponenty poddano analizom chemicznym, w których oznaczono poziom suchej masy, białka ogólnego, tłuszczu surowego oraz włókna surowego. Wyniki doświadczenia potwierdzają hipotezę, że żółwie stepowe charakteryzują się wybiórczością pokarmową, a głównym czynnikiem kierującym nimi w wyborze komponentów paszowych jest zawarta w nich ilość wody. Może to być wytłumaczone przystosowaniem tych gadów do suchego klimatu i rzadkością występowania pokarmów soczystych w ich środowisku naturalnym.

Russian tortoise (Testudo horsfieldii) is one of the most commonly kept in captivity species of reptiles. It is a reason for incorrect opinion that it is easy to maintain proper environment conditions and nutrition for it. The aim of the presented study was to investigate nutritional preferences of adult Russian tortoises kept in captivity. The scientific hypothesis was assumed that Russian tortoises select their feed sources. The experiment was carried out in free choice feeding model and lasted 6 weeks. In this time tortoises were fed with easy accessible and advised in literature groups of feed: fruits, vegetables and herbs. Each of them was used for 2 weeks. Nutritional preferences of tortoises were examined on the basis of the weight of remaining food. All used components were chemically analysed for dry matter, crude protein, crude fat, and crude fibre to find compound or nutrient which is key factor for its selection by tortoises. The results of the experiment confirm the hypothesis that Russian tortoises are selective in terms of feed choice. The main factor which affects their intake is water content in their fresh matter. It can be inter-preted as the result of their evolutionary adaptation for dry environment and rare availability plants with high moisture in natural environment of these reptiles. Additionally, observation of many keepers that turtles prefer yellow and red colours of feed plants were confirmed.

The aim of present study was to evaluate the potential synergistic effect of salinomycin and nisin on gastrointestinal tract microbial ecology and activity as well as the influence of nisin on broiler chicken growth performance. In the first experiment, which lasted 35 days, such dietary additions as: NA – no additives, SAL – salinomycin (60 mg · kg−1 diet), NIS – nisin (2700 IU · kg−1 diet) were used. Nisin addition in comparison to salinomycin and control treatments, improved body weight gain in the entire experiment (days 1–35) as well as increased feed intake and decreased feed conversion ratio, but only in the starter period (days 1–14). In the second experiment the same dietary additions and also SAL+NIS – salinomycin and nisin (60 mg · kg−1 diet and 2700 IU · kg−1 diet, respectively) were applied. The results of the second experiment indicated that salinomycin and nisin combination decreased the total bacteria counts, as well as Enterobacteriaceae, Clostridium perfringens, Lactobacillus spp./ Enterococcus spp. and Clostridium coccoides–Eubacterium rectale cluster in the ileum. Furthermore, the interaction between applied factors was noticed in the decreasing total bacteria counts, Lactobacillus spp. Enterococcus spp., Clostridium coccoides–Eubacterium rectale cluster and increasing signals from Bifidobacterium spp. as well as Streptococcus sp. Lactococcus. There were no interactions between nisin and salinomycin in terms of organic acids concentration in the crop, gizzard, ileum and caecum, as well as pH value, except gizzard. The results of the present study have indicated the positive effect of nisin on broiler growth performance and the fact that nisin and salinomycin can act synergistically in scope of ileal microbiota ecology modification.

The present study aimed to assess the safety issues of supplying kidney bean lectin extract early in life to piglets. Four litters totalling or 30 piglets were used. On postnatal day (PD) 10–11, thirty piglets were divided into 3 experimental groups (T1, T2, and T3), each consisting of 10 animals. On PD 10 or 11, group T1 (control) received water. Groups T2 and T3 received, respectively, a dose of 640 (recommended) and 6400 haemagglutination/piglet (10 x recommended) of kidney bean extract orally in a water suspension. On PD 42, all of the pigs were euthanized, and 6 piglets from each group were randomly taken for necropsy, sampling tissue for histology and bacteriological analyses of the lower gut. Blood was withdrawn before euthanasia for haematology and biochemistry. There were no significant differences in mortality, feed intake or body weight gains among the groups. All examined blood parameters were within the physiological range. No significant effects of the two doses of kidney bean extract on tissue morphology were observed in the post mortem inspection and histology. No significant differences among the groups in the number of aerobic and anaerobic bacteria were found. Concluding, a one-month tolerance study with the recommended and 10-fold recommended dose of kidney bean extract revealed no negative effects on piglet health or performance.
