“…According to Dhayabaran and Thangarathinam [43], palmitic acid has antioxidant, hypocholesterolemic, nematicide, pesticide, lubricant, and antiandrogenic properties. The interaction between palmitic acid and stearic acid decreases cardiovascular illnesses [44]. According to Chandrasekaran et al [45], the methyl ester of tetradecanoic acid has antifungal and antibacterial properties.…”

Background and Aim: Natural antioxidants are crucial for preserving and enhancing the health, survival, reproduction, and reproductive function of poultry. Phycocyanin (PC) is a natural blue food colorant with various health benefits. The aim of this study was to extract Arthrospira platensis phycocyanin (ApPC) from A. platensis using simple and economical methods and investigate the impact of phytocyanin supplementation on the performance and fatty and amino acid profiles of broiler chicks. Materials and Methods: PC was extracted from A. platensis by freezing and thawing, and optimization conditions such as pH and temperature were applied during storage periods. A total of 270 1-week-old Ross breed broiler chicks were randomly assigned to the following three treatment groups: basal diet supplemented with 0 mg of PC/kg diet (control), basal diet supplemented with 1 g PC/kg diet (T1), and basal diet supplemented with 2 g PC/kg (T2). In a completely randomized design, three cage replicates (30 birds each) were assigned to each of the three groups. The dietary effects of ApPC on growth performance (body weight gain [BWG], body weight [BW], feed intake, feed conversion ratio, serum constituents, and antioxidant indices) in broiler chickens, free amino acids, and fatty acids in muscles were evaluated. Results: Total BWG and BW increased without a significant effect on the total feed consumption. Serum levels of total proteins and albumin increased with increasing ApPC supplementation. In addition, globulin levels significantly increased. There was a significant decrease in serum total cholesterol levels among the treatments. The activity of antioxidant enzymes (superoxide dismutase, catalase, glutathione, and total antioxidant capacity) is significantly increased. In contrast, an increase in ApPC caused a significant decrease in malondialdehyde. The content and quantity of fatty acids and amino acids in the meat of broiler chicks supplemented with PC varies. Conclusion: The addition of PC to broiler chicken diets enhances antioxidant activities, BW, BWG, and meets quality requirements. Keywords: Antioxidant, fatty acid, Phycocyanin, poultry, protein, Spirulina.

The high content of fibre and antinutritional phytochemicals limit the utilization of Vachellia erioloba tree pods as nutraceutical feed additive for indigenous chicken diets. The pods can however be solid-state fermented using oyster mushrooms to enhance the nutritional utility of their spent substrate for the nutrition of the native birds. Therefore, this study investigated the effects of dietary incorporation of V. erioloba pods oyster mushroom spent substrate (OMSS) on growth performance, carcass traits, visceral organs, haemato-biochemistry, and meat quality including its fatty acid composition in Boschveld chickens. In a completely randomized design, 250 4-week old mixed gender Boschveld chicks were randomly allotted to 25 pens in which they were offered treatment diets (0, 1.25, 2.5, 5 and 10% OMSS) each with 5 replicates of 10 for 12 weeks and then slaughtered. While there were neither linear nor quadratic effects of diet on overall feed intake (FI) (P > 0.05) and body weight gain (BWG) (P > 0.05), dietary incorporation of OMSS decreased overall feed conversion efficiency (FCE) (quadratic: P < 0.05) particularly in weeks 5 (linear: P < 0.05), 6 (quadratic: P < 0.01) and 11 (quadratic: P < 0.05) with no effects in subsequent weeks (P > 0.05). Also, OMSS induced no effects on all carcass characteristics, visceral organs, haemato-biochemistry and meat physico-chemical quality (P > 0.05) except for the increase in serum albumin (quadratic: P < 0.05) and bilirubin (quadratic: P < 0.05) as well as 24 h post-slaughter meat lightness (linear: P < 0.01), redness (quadratic: P < 0.05), yellowness (linear: P < 0.05), hue angle (quadratic: P < 0.05), and drip loss (quadratic: P < 0.05). Further, the spent substrate decreased meat myristic (linear: P < 0.01), palmitic (linear: P < 0.05), palmitoleic (linear: P < 0.01), and oleic (linear: P < 0.01) acids, as well as its total polyunsaturated fatty acids (PUFAs) (linear: P < 0.05), monounsaturated FAs (MUFAs) (quadratic: P < 0.01), and n-6 PUFAs (linear: P < 0.05). Furthermore, it decreased the meat n-6/n-3 PUFA ratio (quadratic: P < 0.01), with meat from birds fed diets incorporated with 2.5% OMSS eliciting the lowest ratio of 3.63. In contrast, dietary OMSS increased meat stearic (linear: P < 0.001), docosahexaenoic (quadratic: P < 0.01), and tricosanoic (linear: P < 0.001) acid concentrations as well as its total saturated FAs (SFAs) (linear: P < 0.01) and n-3 PUFAs (quadratic: P < 0.01). In conclusion, dietary feeding of V. erioloba pods-derived OMSS enhanced meat nutritional healthiness without majorly altering its physico-chemical quality as well as growth performance, carcass traits, and haemato-biochemistry in Boschveld indigenous chickens. It is recommended for inclusion in indigenous chicken diets at 2.5% level.

In recent years, the use of electronic cigarettes (e-cigs) has increased. However, their long-term effects on oral health and saliva remain poorly understood. Therefore, this study aimed to evaluate the saliva of e-cig users and investigate possible biomarkers. Participants were divided into two groups: the Electronic Cigarette Group (EG)—25 regular and exclusive e-cig users—and Control Group (CG)—25 non-smokers and non-e-cig users, matched in sex and age to the EG. The clinical analysis included the following parameters: age, sex, heart rate, oximetry, capillary blood glucose, carbon monoxide (CO) concentration in exhaled air, and alcohol use disorder identification test (AUDIT). Qualitative and quantitative analyses of saliva included sialometry, viscosity, pH, and cotinine concentrations. Furthermore, the EG and CG salivary metabolomes were compared using gas chromatography coupled with mass spectrometry (GC-MS). Data were analyzed using the Mann–Whitney test. The MetaboAnalyst 6.0 software was used for statistical analysis and biomarker evaluation. The EG showed high means for exhaled CO concentration and AUDIT but lower means for oximetry and salivary viscosity. Furthermore, 10 metabolites (isoleucine, 2-hydroxyglutaric acid, 3-phenyl-lactic acid, linoleic acid, 3-hydroxybutyric acid, 1,6-anhydroglucose, glucuronic acid, valine, stearic acid, and elaidic acid) were abundant in EG but absent in CG. It was concluded that e-cig users had high rates of alcohol consumption and experienced significant impacts on their general health, including increased cotinine and CO concentration in exhaled air, decreased oximetry, and low salivary viscosity. Furthermore, they showed a notable increase in salivary metabolites, especially those related to inflammation, xenobiotic metabolism, and biomass-burning pathways.
