The impact of dietary linseed oil and pomegranate peel extract on broiler growth, carcass traits, serum lipid profile, and meat fatty acid, phenol, and flavonoid contents

Abstract

Objective The current study aimed to replace soybean oil in broiler diets with linseed oil, which is rich in omega-3 fatty acid supplemented with pomegranate peel extract (PPE) and measured its effect on broiler performance, carcass traits, lipid profile, as well as fatty acids composition, phenols and flavonoids content of broiler muscles and immunity of broiler chicks. Methods A total of 300 1-day-old Cobb chicks were randomly allotted into six experimental groups, T1 fed on basal diet with soybean oil without any additives, T2 fed on basal diet with soybean oil with addition of 0.5 g/kg diet PPE, T3 fed on fed on basal diet with soybean oil with addition of 1 g/kg diet PPE, T4 fed on basal diet with linseed oil without any additives, T5 fed on basal diet with linseed oil with addition of 0.5 g/kg diet PPE and T6 fed on basal diet with linseed oil with addition of 1 g/kg diet PPE. The PPE supplementation with 0.05% improved final body weight with either soybean oil ration or linseed oil ration. Results The PPE improved carcass dressing percentage in comparison with the control groups. Body fat levels decreased with increasing PPE levels, especially with a linseed oil diet. Replacing soybean oil with linseed oil decreased the total cholesterol and triacylglycerol levels in broiler serum. The PPE supplementation decreased serum total cholesterol levels and increased high-density lipoprotein cholesterol levels. The content of the breast muscle alpha linolenic acid improved after replacement of soybean oil with linseed oil in broiler diets. PPE supplementation increased the phenol and flavonoid content in broiler meat and increased lysozyme activity. Conclusion Replacing soybean oil with linseed oil in broiler diets with the addition of PPE enriched muscle meat with omega-3 fatty acids and antioxidants and improved broiler immunity and their serum lipid profile.

Effects of dried okra fruit (Abelmoschus esculentus L.) powder on growth, carcass characteristics, blood indices, and meat quality of stored broiler meat

“…However, diets supplemented with DOFP at the level of 1 g/kg feed resulted in the best FCR, during the second and the entire experimental periods. Our results are in agreement with those of Scheuermann et al., 2009 , Hussein et al., 2018 , and Kishawy et al. (2019) who stated that phytogenic additives can enhance the intake and conversion of feed; however, the mode of action of these additives is not clear.…”

Does the use of different oil sources in quail diets impact their productive and reproductive performance, egg quality, and blood constituents?

“…Function, maturation, proliferation, and production of lymphocytic cytokines, splenocytes, and heterophils are influenced by fatty acids, besides production of antibody like IgG and IgM ( Alagawany et al., 2019 ). Furthermore, olive contains flavonoids that are able to improve immune status and increase IgM and IgG ( Christake et al., 2004 , Geetha and Chakravarthula, 2018 , Kishawy et al., 2019 ). These results did not agree with those by Parsaei et al.…”

Cinnamon (Cinnamomum zeylanicum) Oil as a Potential Alternative to Antibiotics in Poultry

“…In alternative strategies, emphasis was placed on preventing the spread of pathogenic bacteria and modifying the bacterial ecosystem of the intestine to improve the overall health and immune status, thereby improving productive performance. The enhancing effect of EO on the feed efficiency and growth performance was due to improving the immune system, regulating the gut micro flora, increasing endogenous digestive enzymes secretion and eliciting antioxidant, antibacterial and anti-viral properties [40][41][42][43]. The effect of cinnamon oil on body weight and weight gain is illustrated in Figure 2.…”
