... Fortuoso et al. (2019) observed an increase in breast muscle yield that corresponded with an increase in total protein content in the serum. Furthermore, as highlighted by Selim et al. (2021), serum total protein serves as an indicator reflecting protein deposition in skeletal muscle. An elevated concentration of serum total protein corresponds to an increased yield in breast muscle. ...
The primary aim of this study was to explore the impact of dietary supplementation with a postbiotic derived from Bacillus subtilis ACCC 11025 on growth performance, meat yield, meat quality, excreta bacterial populations, and excreta ammonia emissions of broiler chicks. A total of 480 day-old Arbor Acre broiler chicks, initially weighing 52.83 ± 1.38 g, were randomly allocated into 4 distinct groups. Each group was housed in 6 separate cages, each containing 20 birds. The experimental phase spanned 42 d, divided into 2 periods (d 1–21 and d 22–42). Dietary interventions were based on a basal diet, with postbiotic supplementation at levels of 0.000, 0.015, 0.030, or 0.045%. Our findings indicate that dietary supplementation with postbiotic had a positive influence on body weight gain (BWG) and feed efficiency. The most substantial improvements in BWG and feed efficiency were observed in the group of broiler chicks fed a diet containing 0.015% postbiotic. Furthermore, the inclusion of postbiotic in the diet led to an increase in the yield of breast and leg muscles, with a significant difference in meat yields observed between the control group and the group receiving 0.015% postbiotic supplementation. It's noteworthy that dietary manipulation did not exert any discernible impact on the quality of breast and leg muscle samples. Concurrently, we observed an elevation in serum albumin and total protein contents corresponding to the increasing postbiotic dosage in the diet. Additionally, dietary supplementation with postbiotic effectively controlled the emission of ammonia from excreta and reduced the abundance of Salmonella in excreta while enhancing the presence of Lactobacillus bacteria. The group receiving 0.015% postbiotic supplementation displayed the lowest levels of ammonia emission and the highest counts of Lactobacillus bacteria in excreta. In light of these results, we conclude that dietary supplementation with 0.015% postbiotic represents an efficacious strategy for increasing BWG and meat yield of broiler chicks by enhancing feed efficiency as well as mitigating ammonia emissions from excreta by modulating the composition of excreta bacterial communities.

... Several studies have shown that the addition of crude rice bran oil to broiler diets could produce beneficial effects similar to those of finished oils, but at a lower cost. 1,2 However, lipoxygenases in rice bran oil can lead to the oxidation and breakdown of unsaturated fatty acids, potentially compromising flavor. 3 Moreover, forming free radicals poses health risks for poultry when consuming oxidized oils. ...
The present study was carried out to evaluate the effects of dietary vitamin E (VE) or grape seed extract (GSE) on the growth performance and antioxidant function of broilers. Two hundred sixteen broiler chicks were randomly assigned to 3 diets: diet supplemented with oxidized rice bran oil (CN group), CN group with 25 mg/kg VE or 100 mg/kg GSE. Dietary VE or GSE improved the growth performance, reverted the disturbed levels of liver antioxidant enzymes, and reduced liver damage of broilers fed oxidized rice bran oil. The mRNA data showed that supplementation of VE or GSE enhanced the antioxidant capacity of the broiler liver through activation of the Keap1-Nrf2/ARE signaling pathway. The results suggested that VE and GSE can increase weight gain, improve the oxidative status, and alleviate liver injury in broiler chicken fed oxidized rice bran oil.
... These fatty acids possess the ability to mitigate the detrimental impacts of free radicals and hinder the production of inflammatory compounds. The ingestion of Salvia hispanica seeds has the potential to improve treatment results in cases of arsenic poisoning [80][81][82][83]. This improvement is attributed to the seeds' ability to increase the production of oxidation enzymes, reduce the amount of lipid peroxides, and protect cells against the detrimental effects caused by free radicals. ...
Chia seeds offer therapeutic properties that aid in the prevention of a variety of ailments, including cardiovascular disease, diabetes, obesity, and other risk factors. Arsenite, a common environmental chemical, has been identified as a reproductive toxin owing to its negative effects on male reproductive health. It has been shown to inhibit spermatogenesis and generate androgenic effects in men. The primary goal of this research was to look into the effect of Salvia hispanica on testicular toxicity caused by sodium arsenite in male rats. A set of 36 male albino rats was allocated to a negative control cohort. The individuals in this group were given a basic meal and orally given distilled water for a duration of 28 days. The other five groups were given a regular meal and received intra-peritoneal injections of sodium arsenite (NaAsO2) at a concentration of 4 mg/kg body weight that was diluted in a 0.9% NaCl solution. The injections were administered consecutively, with two doses given within a two-day period. Subsequently, the rats were categorized into several groups using the following classification: Group 2 consisted of a positive control cohort, in which the rats were given a typical baseline diet. Groups 3, 4, 5, and 6 were given a basic diet that included varying proportions of ground chia seeds, namely 5%, 10%, 15%, and 20% per 100 g of the diet. After the trial was completed, the rats were euthanized, and further biological examination was conducted. The measurements of the reproductive organs were documented and reported. The research assessed the following characteristics: sperm count, motility, progressive motility, and normal morphology. The research included examining serum sex hormones, namely luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone. An evaluation of the activity of antioxidant enzymes was performed in the tissue of the testicles. There were statistically significant improvements in the sperm parameters, serum sex hormone levels, and the activity of antioxidant enzymes, such as GPX, SOD, and CAT, in the therapy groups. The levels of malondialdehyde (MDA) exhibited a noteworthy decrease (p ≤ 0.05) when compared to the positive control group. Salvia hispanica seeds have demonstrated a significant level of effectiveness in reducing sodium arsenite-induced testicular toxicity, which leads to the conclusion. The flavonoid content and antioxidant properties of Salvia hispanica seeds may be to blame for the observed behavior. These indicated characteristics may have therapeutic significance in treating testicular harm induced by arsenite exposure.

The rising global cereal production for human food, feed, and biofuels is accompanied by a surge in quantities of cereal by-products that are not intended for human consumption but are potential alternative energy sources in poultry diets. Their utilization in poultry diets reduces not only poultry feed costs but also the competition between humans and livestock and environmental pollution. Cereal by-products contain a variable amount of nutrients that are useful in poultry nutrition. However, there is limited published information regarding the utilization of cereal by-products as alternative energy sources in poultry diets. Therefore, this review aimed to collate the available information on the proximate composition and inclusion levels of cereal by-products in poultry diets, together with their pertinent issues, for easy retrieval by researchers and nutritionists. In conclusion, good-quality cereal by-products can potentially replace conventional energy sources in poultry diets without adversely affecting poultry performance.
... The utilization of by-products as feed ingredients in poultry diets and their effects on broiler growth performance and health is a strategy that has been investigated in several studies [27][28][29]. Yoghurt acid whey (YAW) is a highly valuable dairy by-product with a composition that depends on the type of yoghurt from which it is derived, thermal processing of milk, storage conditions and more [3]. The applications of YAW in broiler diets are limited mainly due to its high (up to 70%) lactose content [21]. ...
Simple Summary
Greek strained yoghurt is a highly nutritious product with continuously growing production that leads to massive amounts of by-products such as acid whey. The large production of acid whey and the difficulties related to its processing make it a strong pollutant with costly environmental effects. Industry and academia are searching for sustainable applications to repurpose its use. Our research study examined the effects of yoghurt acid whey powder on broiler productivity and meat quality. Consequently, it did not adversely affect performance and enhanced meat quality by extending oxidative stability. In conclusion, yoghurt acid whey powder may be applied in broiler diets when added at 25 g/kg.
Abstract
In recent years, the increasing demand for Greek strained yoghurt produced massive amounts of acid whey, which constitutes a major environmental pollutant. Whether yoghurt acid whey can be included in poultry diets is not known. The purpose of this study was to evaluate the effects of four dietary levels of yoghurt acid whey powder (YAWP) on the growth performance, nutrient digestibility, meat quality traits and oxidative stability. A total of 300 male 1-day-old Ross 308 broilers were assigned into four groups with five replicates of 15 broilers each: control-fed basal diet with no YAWP addition (WO) or basal diet supplemented with YAWP at 25 g/kg of diet (WA), 50 g/kg of diet (WB), or 100 g/kg of diet (WC). At the starter period, body weight and body weight gain were reduced after WB and WC treatments compared to the WO treatment. Breast meat oxidative stability was improved during refrigerated storage for 1 and 3 d in all YAWP treatments compared to control, while the WA treatment showed an improved oxidative stability after 6 and 9 d. The results suggest that YAWP inclusion at 25 g/kg of diet did not impair performance and extended the meat shelf life by reducing lipid oxidation rates.

The study investigated the effect of enzymes as a toxin detoxifier (DETOXIZYME) dietary supplementation on performance during growth, blood chemistry, and immunity under clostridia infection in chickens. A total of 480, day-old male chicks were randomly distributed to four groups, with six replicates of 20 birds each. The first control negative treatment (A) fed the basal formula as commercial feed prepared following the strain's needs, the second control positive group (B) fed the basal formula challenged with Clostridium perfringens (C. perfringens) type A, the third group (C) fed the basal formula with 100 g DETOXIZYME/ton of feed and challenged with clostridia, and the fourth group (D) fed the control basal formula with 100 g DETOXIZYME/ton of feed. DETOXIZYME dietary supplementation significantly boosted body weight (BW), body weight gain (BWG), feed intake (FI), and European production efficiency factor (EPEF) and improved the feed conversion rate (FCR) of the broilers. The dietary supplementation of DETOXIZYME significantly increased carcass trait and spleen. However, liver and abdominal fat weight significantly decreased compared with clostridia-challenged groups. The values of alanine aminotransferase (ALT), aspartate aminotransferase (AST), uric acid, creatinine, and Malondialdehyde (MDA) were decreased. While calcium, phosphate, zinc, and glutathione peroxidase (GPx) levels were improved in birds that took basal formulas fortified with DETOXIZYME contrary to the other treatment groups during 35 days of age. Plasma total cholesterol, triglyceride, and low-density lipoprotein (LDL) values were reduced versus the other treatment groups. Dietary supplementation of DETOXIZYME increased total protein, albumin, globulin, and Newcastle Disease (ND) immunity titer levels in the overall period compared to other groups. Dietary DETOXIZYME supplementation decreased clostridia and E. coli bacteria counts and improved gut morphometry. In conclusion, dietary supplementation of DETOXIZYME had a positive impact on performance, blood biochemistry, immunity, and bacterial counts and improved the gut morphology in broilers under clostridia infection. To serve as a barrier against viruses, toxins, and other detrimental biochemical effects and to allow for the assimilation of nutrients and liquids, the gastrointestinal tract (GIT) of broilers must be in good health 1,2. Furthermore , it enhances mucosal immune response 3,4. Therefore, despite major advancements in feed science and OPEN
... Corn and wheat, containing large amounts of starch, are the main sources of energy for poultry diets; as corn is a multipurpose product and is also human food resources, global trade and its availability have encountered with limitations in recent years) Aderolu et al., 2011;Jahanian & Rasouli, 2014;Omole et al., 2013;Saleh & Alzawqari 2021;Zaghari, 2006). Nevertheless, finding a suitable alternative for poultry feed ingredients (corn, wheat etc.) seems indispensable and several investigators have tried to this end (Kirrella et al., 2021;Saleh & Alzawqari, 2021;Saleh et al., 2020Saleh et al., , 2022Selim et al., 2021); one of the appropriate options for this is agricultural wastes and by-products, namely pasta wastes from the nutritional and economic points of view (Aderolu et al., 2011;Omole et al., 2013;Jahanian & Rasouli, 2014); moreover, it is getting in the centre of attention of researchers in the last decade (Mustamin et al., 2020). ...
Background
Animal food shortage and finding efficient ways to produce poultry products are getting more and more important issues in the world.
Objectives
This study was aimed to determine the effect of replacing corn with pasta wastes (0%, 50% and 100%) in the diet on production performance, some blood variables and the egg quality traits of laying quails.
Methods
A total of 240 laying quails were allocated into 3 experimental groups with 8 replicates for 8 weeks. Egg production percentage, egg mass, feed intake and also mortality rate and percentage of abnormal eggs, egg quality traits and blood variables were evaluated.
Results
None of the pasta wastes inclusion had significant effect on egg mass, abnormal egg percentage, mortality rate, yolk diameter, yolk weight, albumen height, yolk index, shell weight percentage, egg shape index and blood parameters (except for triglycerides). Replacing 100% corn with pasta by‐product reduced feed conversion ratio and increased egg weight values. Replacing 100% corn by pasta wastes significantly increased the albumen weight, shell weight and also egg length and width and decreased the Haugh unit. Replacing 50% and 100% corn had a significant increase in yolk height, egg surface area and significantly decreased shell thickness and yolk colour. Overall, 100% replacement of corn by pasta by‐product increased blood triglycerides compared to the 50% group.
Conclusions
Based on the result of current experiment, total replacement of corn with pasta wastes could increase the egg weight and also improve feed conversion ratio in the laying quail diets.
... Therefore, the improvement in FCR in the present study could be explained by the positive effect of RBO on metabolism and energy expenditure. The current findings related to the improvement of FCR are in agreement with the findings of previous studies [14,36,37]. ...

Evaluating Rice Bran Oil as a Dietary Energy Source on Production Performance, Nutritional Properties and Fatty Acid Deposition of Breast Meat in Broiler Chickens. Foods 2023, 12, 366. https://doi. Abstract: The effects of rice bran oil (RBO) as an alternative dietary energy source on nutritional properties and fatty acid deposition in broiler chickens are scarce in the literature. One-day-old chickens (broiler Ross 308) were assigned in a completely randomized design with three treatment diets and nine replicates of four chickens per replicate. A basal control diet contained 4~5% palm oil (T1) in the starter and finisher phases, respectively. Treatments 2 to 3 were fed diets formulated with 50% (T2) and 100% (T3) of RBO as a fat source instead of palm oil (PO). Replacing dietary PO with RBO improved the feed conversion ratio (FCR) by 6% (p = 0.017) over the total period of the experiment (1-38 d of age). The feeding of RBO (T3) showed the highest (p < 0.001) cooking loss values in the breast meat. However, compared with other groups, the blend of PO and RBO group (T2) displayed a lower cooking loss value in the thigh meat. In breast meat, the protein content was lowered (p = 0.007), while the fat content was higher (p < 0.001) in male broiler chickens fed dietary RBO (T2 and T3). Total inclusion of dietary RBO (T3) decreased (p = 0.034) the proportion of saturated fatty acids (ΣSFAs) but increased (p = 0.02) linoleic acid. In addition, α-linolenic acid (ALA) increased (p < 0.001) in male broiler chickens fed dietary RBO (T2 and T3), and the highest deposit level occurred by the total inclusion of RBO (T3). Total omega 3 fatty acids (∑n-3) increased (p = 0.013), while the ratio of n-6 to n-3 polyunsaturated fatty acid (PUFA) decreased (p = 0.046) in male broiler chickens fed dietary RBO (T3) as compared with the control diet (PO; T1). In conclusion, compared with dietary PO (control diet, T1), the total inclusion of dietary RBO at 50 kg/metric ton feed (T3) increased ∑n-3, ALA, and reduced n-6:n-3 PUFA ratio in the breast meat, but cooking loss values were larger in breast and thigh meats. The blend of dietary PO and RBO (T2) was better for both production performance targets (feed intake and FCR), cooking loss values, and deposition of ALA in the breast meat. The inclusion of dietary RBO into broiler diets needs further study, but the present experiment aids in expanding research knowledge to make that possible.
