The influence of dietary supplementation with oyster mushroom waste on laying hens' performance, egg quality and immune parameters.

The objective of the present study was to evaluate the effects of dietary supplementation with oyster mushroom (Pleurotus ostreatus) waste (OMW) on performance, egg quality, fatty acid (FA) profile and oxidative stability, serum and yolk cholesterol and immune parameters of laying hens. Two hundred fifty-six laying hens were allocated into 4 treatment groups, with eight replicate cages, and were fed for 28 d either a control diet, or diets supplemented with OMW at 1, 2 or 4 g per 100 g feed (P1, P2 and P4 experimental groups, respectively). No significant effects were detected on the performance and egg quality (P > 0.

Effect of Dietary Supplementation with a Mixture of Natural Antioxidants on Milk Yield, Composition, Oxidation Stability and Udder Health in Dairy Ewes.

Due to the limitations in the use of antibiotic agents, researchers are constantly seeking natural bioactive compounds that could benefit udder health status but also milk quality characteristics in dairy animals. The aim of the current study was therefore to examine the effects of a standardized mixture of plant bioactive components (MPBC) originated from thyme, anise and olive on milk yield, composition, oxidative stability and somatic cell count in dairy ewes. Thirty-six ewes approximately 75 days after parturition were randomly allocated into three experimental treatments, which were provided with three diets: control (C); without the addition of the mixture, B1; supplemented with MPBC at 0.

The Effects of Yoghurt Acid Whey Marination on Quality Parameters of Pork and Chicken Meat.

Large amounts of yoghurt acid whey (YAW) are annually generated as a result of Greek-style yoghurt production, which poses a great hazard to the environment. In terms of sustainability, YAW application in the meat industry appears as a great alternative since meat marination with natural solutions is a practice that continuously gains ground due to its positive effects on meat sensory attributes. The aim of the present study was to determine the quality characteristics and oxidative status of pork and chicken meat after their marination in yoghurt acid whey.
