“…[ 24,25 ] The incorporation of natural antioxidants by dietary means is an effective and practical strategy for controlling lipid oxidation and protein oxidation related products and providing wholesome nutritious products to health‐conscious consumers. [ 26 ] Dietary supplementation of TCSM had no effect on lipid oxidation and protein oxidation in breast and thigh muscle of broiler chickens. This observation was unexpected given the increase in the concentration of readily oxidized n‐3 PUFA in the meat of birds fed 2.5% and 5% TCSM.…”

“…Dietary supplementation of antioxidants is a potent strategy for promoting the oxidative stability of intact muscle, in which the use of exogenous antioxidant may be practically impossible or difficult. [ 26 ] T. conophorum seed is rich in myriad phytochemicals whose antioxidant properties have been espoused. [ 27,28 ] Thus, T. conophorum seed may be a potential source of natural antioxidants that could be utilized to prevent oxidative spoilage in animal‐derived foods.…”

The influence of dietary Tetracarpidium conophorum (African Walnut) seed meal (TCSM) on fatty acids, productivity parameters, and physicochemical properties of breast and thigh muscles in broiler chickens are assessed. A total of 180, 28-d-old Arbor acre broiler chickens are randomly assigned to dietary treatments containing 0% (control), 2.5%, and 5% w/w TCSM, fed for 28 d, and euthanized. Dietary TCSM reduces (p < 0.05) feed intake, body weight gain (BWG), carcass weight, and abdominal fat. Diet does not affect feed efficiency and hematological parameters. The control birds have higher (p < 0.05) serum total cholesterol and triglycerides than do the supplemented birds. Diet has no effect on pH, water holding capacity, carbonyl and malondialdehyde contents, and organoleptic properties of breast and thigh muscles. The 5% TCSM has higher redness in breast muscle than do other treatments. Dietary TCSM improves (p < 0.05) the concentration of C18:3n-3 (4.80-8.76% vs 1.56%), C20:5n-3 (0.54-0.79% vs 0.39%), C22:5n-3 (0.64-0.89% vs 0.18%), and C22:6n-3 (0.75-0.97% vs 0.19%), and reduces (p < 0.05) the fat content (2.15-2.45% vs 3.15%) in breast and thigh muscles. Dietary TCSM enhances muscle n-3 fatty acids without instigating oxidative deterioration, but reduces BWG in broiler chickens. Practical Application: Albeit that broiler meat is rich in polyunsaturated fatty acids (PUFA), its omega 6 (n-6)/omega 3 (n-3) is >4. Elevated n-6/n-3 could have adverse effect on human physiology thereby promoting the pathogenesis of certain diseases. This heightens the need to enhance the n-3 PUFA content of broiler meat. Dietary TCSM induced up to a fourfold increase in n-3 PUFA content of the breast and thigh muscles in broiler chickens. Moreover, dietary TCSM induced up to a tenfold decrease in the n-6/n-3 of the breast and thigh muscles in broiler chickens. This finding assumes great significance because the health concerns regarding dietary fat are the foremost factors responsible for the bad image suffered by meat. These results provide insights on the potential of TCSM to improve the nutritional quality without compromising the oxidative shelf life, organoleptic traits, and physicochemical properties of broiler meat.

“…In the present results, although the proportion of aldehydes in WRF meat was largely increased, it was still difficult to conclude whether feeding WRF-pretreated corn straw improved meat flavor, because for SM muscle, all kinds of volatile flavor compounds were lower in WRF than CON, whereas for LTL muscle, aldehydes, acids, ketones and amines were higher in WRF than CON. Contrasting effects on different muscles may be due to different physiological processes, including differences in lipid and protein metabolites and impact of diets on muscle varying with muscle type [ 48 ]. Data regarding effects of WRF on meat flavor are limited and further studies are needed.…”

Infections with gastrointestinal nematodes (GIN) adversely affect meat color in lambs. Although white-rot fungi (WRF) pretreatment increases nutritional value and fiber digestion of corn straw for lambs, whether it can improve meat quality of lambs infected with GINs is unknown. The objective of this experiment was to study effects of feeding WRF-pretreated corn straw on the health and meat quality of lambs infected with GINs. Sixteen healthy Ujumqin lambs were orally drenched with 3rd-stage GINs larvae and randomly divided into two dietary treatments of control (CON) and WRF diets for 70 days of feeding. Results showed that feeding WRF-pretreated corn straw decreased L* and b* values (p < 0.05) and increased a* value (p < 0.01) of both longissimus thoracis et lumborum (LTL) and semimembranosus (SM) muscles of lambs infected with GINs. Feeding WRF-pretreatment corn straw decreased fecal egg count (p = 0.014) and increased packed cell volume (p = 0.013) of lambs from 28 d of feeding and increased plasma iron content (p = 0.008) of lambs from 56 d of the feeding. Feeding WRF-pretreatment corn straw decreased myosin heavy-chain (MyHC)-I (p = 0.032) and MyHC-IIα (p = 0.025) content in LTL muscle and MyHC-I (p = 0.022) and MyHC-IIβ (p = 0.048) in SM muscle of lambs. In conclusion, although there were no significant changes in the content of most amino acids or increased intensity of better flavor compounds, meat quality and health of lambs infected with GINs was significantly improved by feeding WRF-pretreated corn straw due to increased PCV and meat color and tenderness.

“…This aspect is very significant in the production of functional meat products that are tasty and satisfying (22). Fatty acid and vitamin E content can be changed through modify the ruminant's feed (23) for example adding herbal plants to the diets could improve fatty acid profile in muscle in lambs (24). It should be possible to create new meat products with potential health benefits by incorporating natural bioactive compounds.…”

The use of herbal plants as food additives in animal nutrition to enhance meat processing efficiency and meat quality has been reviewed. Today, the consumer demand is safety, nutritive value, taste, uniformity, meat variety and good appearance of meat products. Thus, to meet the consumers' demand, development of product and research should be improved. Studies have been shown that the use of herbs, spices, and their extracts are of the major interventions, which were adopted in the industry of the meat for improving its quality traits. In the present paper, the most recent literature about use of bioactive compounds in herbal plants for evaluating a number of parameters related to meat quality, including fat content and distribution, water content, water holding capacity, collagen content, pH, tenderness color, Lipid oxidation and flavor were reviewed.
