Effects of fermented rapeseed meal on performance, intestinal morphology, the viscosity of intestinal content, phosphorus availability, and egg quality of laying hens.

Fermented rapeseed meal has the potential to partial replace soybean meal in feed mixtures for poultry without a negative impact on the health condition and performance of birds. This is due to the fact that the fermentation process can reduce the amount of antinutritional factors, improve the use of nutrients and impart probiotic properties to rapeseed meal. Therefore, this study was undertaken to investigate the effect of fermented rapeseed meal on the performance, egg quality, intestinal morphometry, the viscosity of intestinal content and total phosphorus availability.

Influence of solid state fermentation with Bacillus subtilis 67 strain on the nutritional value of rapeseed meal and its effects on performance and meat quality of broiler chickens.

The study aimed to evaluate the influence of solid-state fermentation on the nutritional value and enzymatic activity of rapeseed meal and its effects on the performance of broiler chickens and meat quality, including physicochemical properties (proximate analysis, pH, water holding capacity), antioxidant capabilities, dipeptide composition of the meat and sensory traits. Three dietary treatments were evaluated using broiler chickens: a control without incorporation of rapeseed meal; a second treatment with the incorporation of 3% unfermented rapeseed meal; and a third with the incorporation of 3% rapeseed meal fermented with Bacillus subtilis 67. The study showed that fermented compared to unfermented rapeseed meal was characterized by a significantly higher content of dry matter, crude ash, crude fat and metabolic energy (P < 0.

Recent innovations in various methods of harmful gases conversion and its mechanism in poultry farms.

Poultry breeding takes place in intensive, high-production systems characterized by high animal density, which is a source of harmful emission of odorous volatile organic compounds (VOCs), ammonia (NH3), hydrogen sulfide (H2S) and greenhouse gases, which in turn sustain animal welfare. This study identified and examined the characteristics of chemical compounds emitted in intensive poultry farming (laying hens, broilers) and their toxicity, which led to recommending methods of deodorization. Emphasis was placed on the law relative to air purification in poultry farms.

Preliminary Evaluation of Thulium Doped Fiber Laser in Pig Model of Liver Surgery.

Partial liver resection is a treatment of choice for liver tumors; the range of parenchyma excision varies from a small part of the tissue surrounding the neoplasm up to 70% of the organ. One of the major concerns during liver resection is blood loss. Thulium lasers which are characterized by the length of emission wave corresponding to a peak absorption of water create a new possibility of cutting tissues efficiently with minimal thermal damage and concurrently providing a good hemostasis control.
