“…Various studies (Table 1 ) have shown diet supplementation with finger millet and corn straw (Chen et al., 2020 ), licuri ( Syagrus coronate ) cake (Bagaldo et al., 2019 ), dried lucerne and soybean oil (Bessa et al., 2005 ), chromium‐yeast (Domínguez‐Vara et al., 2009 ), spineless cactus (Cardoso et al., 2021 ), macadamia oil (Dias Junior et al., 2022 ), chitosan (Pereira et al., 2020 ), and fennel ( Foeniculum vulgare ) seed powder (Shahsavari et al., 2021 ) to increase body weight and ADG despite decreases in dry matter intake, thus leading to increases in FE. This increase in body weight and ADG can be traced back to the differing intestinal absorption rates among different diets, which has the greatest impact on weight gain and plays a critical role in the lambs’ ability to extract nutrients from food, ultimately affecting growth and development.…”

“…This increase in body weight and ADG can be traced back to the differing intestinal absorption rates among different diets, which has the greatest impact on weight gain and plays a critical role in the lambs’ ability to extract nutrients from food, ultimately affecting growth and development. These diets also exhibited excellent antioxidant, antimicrobial, and hepatoprotective properties, and were found to be rich in conjugated linoleic acid, and palmitoleic acid which decrease lipogenesis and fat depositions (Bagaldo et al., 2019 ; Cardoso et al., 2021 ; Chen et al., 2020 ; Dias Junior et al., 2022 ; Domínguez‐Vara et al., 2009 ; Pereira et al., 2020 ; Santos‐Silva et al., 2004 ; Shahsavari et al., 2021 ). In contrast, protein enriched fermented feed (Malik et al., 1999 ), polyherbal mixture diet (containing polysaccharides, flavonoids, and saponins) (Orzuna‐Orzuna et al., 2021 ), and calcium salts of fatty acids (Seabrook et al., 2011 ), were observed to reduce animal growth by boosting dry matter intake which resulted in decreased FE (Table 1 ).…”

“…These diets had lower levels of neutral detergent fiber, which influenced the reduction in the contents of the gastrointestinal tract due to the diets' quick ruminal degradability. Several other investigated diets such as crushed crambe (Carneiro et al., 2016 ), lycopene (Jiang et al., 2015 ), macadamia oil (Dias Junior et al., 2022 ), sunflower cake (Melo et al., 2019 ), N. sativa seeds and R. officinalis leaves (Odhaib et al., 2018 ), chitosan (Pereira et al., 2020 ), linseed, and marine algae (Urrutia et al., 2016 ) were reported to yield satisfactory results for the meat quality parameters such as pH, cooking loss, shear force, color, and water holding capacity (Table 1 ).…”

Feed costs and carcass yields affect the profitability and sustainability of sheep production. Therefore, it is crucial to select animals with a higher feed efficiency and high‐quality meat production. This study focuses on the impact of dietary and genetic factors on production traits such as feed efficiency, carcass quality, and meat quality. Diets promote optimal sheep growth and development and provide sufficient protein can lead to higher‐quality meat. However, establishing an optimized production system requires careful consideration and balance of dietary parameters. This includes ensuring adequate protein intake and feeding diets with higher intestinal absorption rates to enhance nutrient absorption in the gut. The study identifies specific genes, such as Callipyge, Calpastatin, and Myostatin, and the presence of causal mutations in these genes, as factors influencing animal growth rates, feed efficiency, and meat fatty acid profiles. Additionally, variants of other reported genes, including PIGY, UCP1, MEF2B, TNNC2, FABP4, SCD, FASN, ADCY8, ME1, CA1, GLIS1, IL1RAPL1, SOX5, SOX6, and IGF1, show potential as markers for sheep selection. A meta‐analysis of reported heritability estimates reveals that residual feed intake (0.27 ± 0.07), hot carcass weight (0.26 ± 0.05), dressing percentage (0.23 ± 0.05), and intramuscular fat content (0.45 ± 0.04) are moderately to highly heritable traits. This suggests that these traits are less influenced by environmental factors and could be improved through genetic selection. Additionally, positive genetic correlations exist between body weight and hot carcass weight (0.91 ± 0.06), dressing percentage (0.35 ± 0.15), and shear force (0.27 ± 0.24), indicating that selecting for higher body weight could lead to favorable changes in carcass quality, and meat quality.

“…SREBP-1c activates the transcription of genes such as acetyl-CoA carboxylase (ACACA), fatty acid synthase (FASN), elongases (ELOVL), stearoyl-CoAdesaturase (SCD-1), and other genes that participate in bioenergetics, adipogenesis, lipolysis, and synthesis of new fatty acids and triglycerides [13][14][15]. Previous studies have reported gene expression related to fat metabolism in lambs [16,17]; however, there is a lack of information on gene expression due to the effects of different feeding systems.…”

The aim of this study was to investigate the effects of feeding systems on the growth performance of Santa Inês x Dorper lambs, meat quality, fatty acid profile, and gene expression. Thirty lambs at an initial body weight of 22.6 ± 2.59 kg were randomly assigned to one of three feed systems: a grazing system with 1.2% body weight concentrate supplementation (GS); a feedlot system with 28% forage and 72% concentrate (FFC); or feedlot with 85% whole corn grain and 15% pellets (FHG). The lambs were slaughtered after 60 days of experiment. Average daily gain, glucose, and insulin concentration were higher for lambs on FHC than lambs on a GS feeding system. The fatty acid profile in the meat of the lambs fed GS showed a higher proportion of c9t11-C18:2, C20:5, C22:5, and C22:6 compared with FFC and FHC (p < 0.05). Meat tenderness was lower for lambs under FFC treatment compared with GS and FHG. FHG treatment provides better performance and higher deposition of lipid content in meat compared with GS and FHG. The expression of the genes SCD-1, SREBP1-c, and EVOL6 was greater in lambs undergoing GS and FHC treatments compared with FFC. Results of this research showed a reduced performance of grazing lambs compared with the feedlot system; however, it enhanced the fatty acid profile with increased levels of polyunsaturated acids and reduced n6/n3 ratio.

The current research aimed to assess the effects of dietary macadamia oil (MO) on carcass traits, growth performance, physio‐biochemical components, immune function, thyroid hormones and inflammation markers of growing rabbits. A total of 96 growing rabbits were randomly distributed into four treatments, with 24 rabbits in each group. The rabbits were fed a basal diet (control group) or a diet supplemented with MO at 0.5 (MO0.5), 1 (MO1.0) and 2 (MO2.0) mL/kg of diet for eight weeks. The daily body weight gain and feed conversion ratio showed a quadratic improvement with increasing levels of MO, and the optimal dose was 1.25 mL/kg of diet. Increasing levels of MO also had a quadratic effect on hepatic and renal functions. Dose‐response curves revealed that the optimal doses of MO were 1.50, 1.75 and 1.25 mL/kg of diet for total bilirubin, gamma‐glutamyl transferase, and creatinine respectively. A quadratic relationship was observed between the increased levels of MO and tumour necrosis factor‐α (p = 0.038), interleukin‐6 (p = 0.014) and immunoglobulins (p = 0.016 and IgM p = 0.026). Additionally, a linear relationship was observed between the increment in MO levels and both nitric oxide (p = 0.040) and interleukin‐4 (p = 0.001). The activities of superoxide dismutase and glutathione peroxidase showed a linear increase with increasing dietary MO content, while xanthine oxidase showed a linear decrease. Total antioxidant capacity showed quadratic improvement (p = 0.035) with the dietary treatment, with the optimal dose observed at 1.25 mL/kg of diet. The inclusion of MO in the diet had a linear effect on the activity of thyroxine (p = 0.001). Therefore, supplementation of MO at a dose of 1 or 1.5 mL/kg of diet in growing rabbits' diets can improve growth and carcass traits, sustain thyroid function by supporting immunity, and reduce oxidative/inflammation pathways.
