Impact of dietary cold-pressed chia oil on growth, blood chemistry, haematology, immunity and antioxidant status of growing Japanese quail

Abstract

Chia (Salvia hispanica L.) is a member of Labiate family and its seeds are rich in phenolic compounds and polyunsaturated fatty acids (PUFAs) which could enhance the performance and productivity of birds. This study was carried out to determine the effects of supplementation with cold-pressed chia oil at different concentrations on the growth performance, carcase traits, haematology, blood chemistry, immunity and antioxidant status of growing quails. A total of 240 growing quails (1 week-old) were divided equally into five groups (4 replicates with 12 birds each). The experimental groups were GBirds in the G 2 group exhibited the highest body weight at 3 and 5 weeks of age, and the highest body weight gain at 1-3 weeks (6.24 g) and 1-5 weeks (6.17 g). Birds fed diets enriched with 0.4% chia oil exhibited the best FCR values. Dietary supplementation with chia oil increased the red blood cells (RBCs), white blood cells (WBCs), haemoglobin (HGB) and haematocrit (HCT) when compared to the control group (G 1 ). The antioxidant and immunity parameters were not affected by the supplementation of diet with chia oil. This study showed that quail diet supplementation with 0.4 g chia oil/kg diet improved the growth performance, certain blood parameters and lipid profile. HIGHLIGHTSPhytobiotics recently achieved an attention in poultry feed. Cold-pressed chia oil dietary supplementation for quail diet. G 2 possessed the heaviest bodyweight and consumed the lowest feed with the best feed conversion ratio. Quail diet supplementing with 0.4 chia oil/kg diet, improved the growth performance, some blood parameters, lipid profile and immunity.

The Neonicotinoid Thiacloprid Interferes with the Development, Brain Antioxidants, and Neurochemistry of Chicken Embryos and Alters the Hatchling Behavior: Modulatory Potential of Phytochemicals

“…Other neonicotinoids, such as imidacloprid [ 44 , 45 ], thiamethoxam, and nitenpyram [ 46 ], changed the antioxidant biomarkers of fishes. The significant reduction in the activity of SOD observed in the TH group could be probably attributed to the excessive ROS production and the inability of the antioxidant system to thoroughly remove the excess free radicals from the body [ 47 , 48 , 49 ]. Neonicotinoids have also been reported to attack mitochondria, impairing their functions and increasing ROS production [ 50 ].…”

The Strategy of Boosting the Immune System Under the COVID-19 Pandemic

“…Phytogenic feed additives exert their favorable health improving effects owing to their content of active substances such as polyphenols and secondary metabolites. Polyphenols are found in vegetables, grains, fruits, and green and black tea in different parts of the plant (leaves, roots, flowers, seeds, and fruits) to protect the plant immune system against UV radiation and pests (141)(142)(143)(144)(145)(146)(147)(148)(149)(150)(151).…”

Probiotics in poultry feed: A comprehensive review

“…Feed additives and nutritional supplements are attaining importance nowadays in the poultry industry, as well as in healthcare systems, because of their wide spectrum of beneficial impacts, such as promoting growth and production, immune enhancement and health protection (Alagawany, Abd El‐Hack, et al, 2018; Alagawany, Elnesr, et al, 2018; Alagawany, Elnesr, & Farag, et al, 2019; Alagawany, Elnesr, Farag, Abd El‐Hack, et al, 2019; Alagawany et al, 2020; Arif et al., 2019, 2020; Shewita & Taha, 2018). Moreover, non‐nutritional factors such as hygiene, processing of feed ingredients, ambient temperature, animal health and genetic makeup have an impact on animal performance (Chlebicz & Slizewska, 2020; Jacob, 2015; Mohamed et al., 2019).…”
