... Cognitive impairment due to aging was attenuated by improved cognitive performance in older mice and decreasing levels of inflammatory mediators such as IL-1β and TNF-α in response to resveratrol [117], and aged mice that received resveratrol showed improvements in cerebrovascularity [118]. In response to a high-fat diet in rats, resveratrol or alpha-ketoglutarate (aKG) improved brain and metabolic aging profiles, notably through inflammatory response genes [119]. Witte et al., 2014, analyzed resveratrol administration at 200 mg daily in older adults to affect memory performance, hippocampal connectivity, and glucose metabolism. ...

... Up to now, available research on the SWM as poultry feed is still scarce compared to that conducted on the most common insect species such as Hermetia illucens, Tenebrio molitor, or Musca domestica: key aspects for an emerging feed ingredient such as those linked to species-specific optimum inclusion levels and inclusion period (starter, grower, finisher stage of the whole farming cycle) remain to be investigated. Furthermore, published results concerning SWM utilization in poultry diets still leave some gaps: in some studies, no negative effects on chicken performance were noticed [14][15][16][17], while in other studies some possible critical points related to SWM utilization have been highlighted. Specifically, Miah et al. [14] highlighted that the inclusion of either 7% or 14% of defatted SWM in the diet of chickens was not optimal as both inclusion levels increased feed intake and reduced the protein content of meat. ...

... The recoveries both in meat and meat products as in derivatives of livestock were equivalent (Du and Ahn 2002;Mariutti et al. 2008;Gasior and Pietras 2013;Bauer et al. 2014; Domínguez et al. 2018;Grasso et al. 2019;Maslukhah et al. 2019;Kolarič and Šimko 2020a) or even better (Cayuela et al. 2003;Mazalli et al. 2006;Mestre Prates et al. 2006;Dinh et al. 2012;Luzia Stroher et al. 2012;Park et al. 2013) than others reported in the literature as can see in Table 2. ...

... Camelina seeds contain up to 40% oil, 90% of which is made up of unsaturated fatty acids: 30-40% fraction of α-linolenic acid, 15-25% fraction of linoleic acid, 15% fraction of oleic acid, and around 15% eicosenoic acid [1]. Camelina oil is considered a high-quality edible oil [14]. This crop is interesting because it has several attractive traits, such as a high ability to adapt to marginal soils and low input growing conditions. ...

... Moreover, camelina cake is also rich in crude protein (30-35%) with a good content of essential amino acids like leucine, valine, lysine, phenylalanine, and isoleucine (Colombini et al., 2014;Bătrîna et al., 2020). Thanks to all these positive features, camelina cake could be a promising alternative feedstuff for poultry diets (Lolli et al., 2020;Mondor and Hernández-Álvarez, 2021;Orczewska-Dudek and Pietras, 2019;Oryschak et al., 2020;Untea et al., 2019;Zając et al., 2020;Zając et al., 2021). ...

... Applicable nanotechnology approach can be used to solve gas emission problems with some nanomaterials. For instance, using SiO 2 as a feed additive can reduce ammonia emission in the body metabolic system (Pieszka et al., 2018). Another example is an approach to animal waste management involving adding nanoparticles to manure to enhance biogas production from anaerobic digesters or to reduce odours (Scott, 2007). ...

... It is reported that sea buckthorn (SBT) pomace influences the colour, pH and rheological properties of eggs [173]. It can be used as a natural preservative rich in antioxidants and to inhibit lipid oxidation in breast muscles without altering the physicochemical properties [174]. In a study undertaken by Sharma et al. 20% of the crude protein of the traditional concentrate has been replaced with sea buckthorn cake in layer birds to evaluate its effect on egg production [175]. ...

... In recent years, the growing demand for high quality poultry products has provided an opportunity to increase the importance of keeping native or locally adapted breeds of hens (Amorim et al., 2016;Obrzut et al., 2018;Calik et al., 2020). In Poland, 8 breeds (including 11 lines of laying hens) are under conservation, most of which are listed in the World Watch List (2000). ...

... A 100-g portion of fresh meat of these two groups of red deer contained approximately 57-62 mg of cholesterol, which corresponds to only 20% of the recommended daily intake (Table 5). It should be emphasized that a small amount of cholesterol in the daily diet is desirable, as it is an important component of the cell membrane, brain, and steroidogenic tissue, but its excess may cause coronary artery disease [73]. ...

... A gas chromatographic validated method was used for the determination of cholesterol in egg yolks (Gąsior & Pietras, 2013). The method involves KOH (60 g/100 ml) saponification and hexane extraction of the cholesterol. ...
