Silica-Calcite Sedimentary Rock (Opoka) Enhances the Immunological Status and Improves the Growth Rate in Broilers Exposed to Ochratoxin A in Feed.

Mycotoxins, such as Ochratoxin A (OTA), originating from fungi like Aspergillus and Penicillium, represent serious health hazards to poultry. The use of mycotoxin-adsorbing feed additives can reduce these risks. Opoka, a porous transitional rock, shows promise as one of these additives.

Effect of radiant catalytic ionization on environmental conditions in rodent rooms and the haematological status of mice.

High stocking densities, closed animal houses, and elevated concentrations of bacteria, fungi, and the products of their activity, including ammonia and hydrogen sulphide, have adverse health effects. Active techniques used to reduce unfavourable environmental conditions, such as ventilation, sprinkling, bedding sorbents, and nutritional treatments, are not always sufficient to improve the animals' living environment. The current paper aims to evaluate the effect of radiant catalytic ionization (RCI) on airborne microorganisms, cage microbiological status, gaseous ammonia concentrations, and the haematological status of mice in animal houses.

Using Milk Thistle () Extract to Improve the Welfare, Growth Performance and Meat Quality of Broiler Chicken.

Modern poultry production looks for feed and water additives that improve the welfare of chickens. The utilization of herbs as additives in feed or drinking water is becoming increasingly well known. The aim of this study was to determine the effect of milk thistle extract (), administered in drinking water, on chickens' welfare, production results, selected physicochemical properties of the breast muscles, the activity of selected enzymes, and the antioxidant potential of blood serum and breast muscles.

Radiant catalytic ionization improves the microbiological status of rodent facilities without affecting the prooxidative status of mice.

The main microbial contaminants of rooms in which laboratory rodents are housed are bacteria and fungi. Restriction of microbial growth to below threshold levels requires the application of various sophisticated antimicrobial techniques that must be effective and safe for the animals. Some of the most commonly used techniques, including chemical disinfection, ventilation, filtration, sterilization and radiation, are not always sufficiently effective.

Impact of Ag Nanoparticles (AgNPs) and Multimicrobial Preparation (EM) on the Carcass, Mineral, and Fatty Acid Composition of Snails.

The hygienic practices on farms should reduce pathogenic microorganisms while simultaneously not harming the animals themselves; they must also not degrade the products' quality. We assessed the effect of covering feed tables with paint containing silver nanoparticles (AgNPs) and the periodic spraying of effective microorganisms (EM) on production indicators and basic chemical composition, mineral content and fatty acid profiles in the bodies of snails. The animals were divided into four groups: (1) control, (2) with feed tables covered with AgNPs paint, (3) with EM spray applied and (4) with both factors-AgNP paint and EM spray.

Effect of (Thunb.) fruit extract on HO-induced oxidative and inflammatory responses in normal fibroblast cells.

Background: is a plant commonly used in traditional Asian medicine for its many health benefits and strong antioxidative activity. Its therapeutic potential is believed to be connected to its effect on fibroblasts. This study aimed to investigate methanol-acetone extract's (EUE) defense against hydrogen peroxide (HO)-induced fibroblast damage.

The Effect of Ag Nanoparticles and Multimicrobial Preparation as Factors Stabilizing the Microbiological Homeostasis of Feed Tables for (Müller) Snails on Snail Growth and Quality Parameters of Carcasses and Shells.

The aim of this research was to evaluate the effect of Ag nanoparticles (nano-Ag) used in the paint covering feed tables or a multimicrobial preparation applied to feed tables on the microbiological composition of the feed table environment, the growth and mortality of snails, and selected parameters for assessing the quality of carcasses and snail shells. The research was carried out in a farm of (Müller) snails. In the control (K) group, paint without nano-Ag was used.

Effect of the diets with pumpkin silage and synthetic β-carotene on the carotenoid, immunoglobulin and bioactive protein content and fatty acid composition of colostrum.

Forty Simmental cows were divided into four groups with 10 per group to investigate the effect of a transition diet supplemented with synthetic β-carotene and natural carotenoid-rich feed (pumpkin silage) on chemical composition of the colostrum. The control group (I) was fed grass and maize silage and supplemental concentrates, group II additionally received 400 mg/day/cow of synthetic β-carotene, in group, III 40% DM of maize silage was replaced with pumpkin silage to increase β-carotene intake by 400 mg in relation to group I, and in group IV 60% DM of maize silage was replaced with pumpkin silage without adjusting for β-carotene. Colostrum was collected from the cows within 5 hr of calving to determine colostrum composition, the content of immunoglobulins and carotenoids, total antioxidant status (TAS), the content of some bioactive proteins and the composition of fatty acids.

Effect of copper nanoparticles on the mineral content of tissues and droppings, and growth of chickens.

We hypothesised that copper nanoparticles (NanoCu), because of their high physicochemical reactivity and bioavailability, could be used in much smaller quantities than bulk Cu, consequently reducing excretion of Cu into the environment. The objective of the study was to evaluate the effects of various levels of NanoCu on the development and growth of broiler chickens, in order to establish an optimum level of NanoCu dietary supplementation. Broiler chickens were randomly divided into five groups of 10 birds each.

Effect of heparan sulfate and gold nanoparticles on muscle development during embryogenesis.

Purpose: It was hypothesized that heparan sulfate (HS) as an essential compound for myogenesis and nanoparticles of gold (nano-Au) as highly reactive compounds can affect muscle development as a consequence of molecular regulation of muscle cell formation, and that these effects may be enhanced by a complex of HS conjugated with nano-Au. The objective of the present study was to determine the effect of administration of nano-Au, HS, and a nano-Au+HS complex on the morphological and molecular characteristics of breast muscle during embryogenesis.

Methods: Chicken embryos were used as in vivo model.
