    Effet des extraits du Figuier de Barbarie ( Opuntia- Ficus- indica) sur le dévloppement des lapins ORYCTOLAGUS CUNICULUS
    (2024) Bouguerche Faiza
    Due to multiple uses of Opuntia Ficus Indica, we dedicated a quantitative study following a biological analysis on seeds, or this species was collected on Out 2021 from the area of Sidi-Fredj wilaya of Souk-Ahras (North-East Algeria). In the present study, the chemical analysis of the seeds powder of barbaric fig seeds reveals a moisture percentage of 92% of the dry matter. A yield of 4.36±0.57 and 5.76±0.55 for hydromethanol extract and ethyl acetate respectively. Phytochemical screening reveals the presence of certain secondary metabolites such as tannins, flavonoids, alkaloids, amines, polyphenols and steroids, and the absence of others such as reducing sugars and quinones, in the different types of extracts. The quantitative analysis was carried out on four types of organic extracts; Methanol, Ethyl Acetate, Ethanol and Hexane, passed by the dosage of Tanins, Flavonoids, and Total Polyphenols. The results obtained from quantitative analyses show that the methanoic extract still has higher values for the three dosages, (316ug/ml±14,42; 182,51ug/ ml±2,18; 454,33ug/mL±2,08 respectively), following the ethyl acetate (283,38ug/ mL±1,19; 118,33g/m L±1,52; 409,4ug/ML±0,52 respectively). Antioxidant power in vitro was estimated by total antioxidant activity, it shows that ethyl acetate and methanol have moderate activity by intake of hexan and ethanol (3.91ug/ml±0.74; 3.56ug/mL±1.15; 3.27ug/ML±0.11; 3.01ug/ms±1.02 respectively), the FRAP iron reduction test has an CI50 of 22.09ug/mm±2.73 in methanole as the most active extract, that of Ascorbic acid 1.21ug/mg±0.36 as positive test indicators.For the 2.2-diphenyl-1-picryi-hydrazyl radical reduction test the ethanol extract has an CI50 of 2.19ug/ml±1.16 as the next highest value of Ethyl Acetate with an IC50 of 1.93ug/mL±0.54With regard to the beta-carotene bleaching test the important anti-radical activity is observed in methanol following ethyl acetate (%AA = 2,04ug/ml±0,46; 1,82ug/mL±0,33 respectively). On the other hand, the in vivo study on rabbits OryctolagusCuniculs treated with the feed from seed ‘the turtles, shows a better evolution of the rabbit weight under feeding for the improvement of weight gain, nutritional efficiency and carcass yield in rabbis at the age of 71 days Best dietary and organoleptic quality of rabbit meat species. Biochemical analyses show disturbances in some parameters and decreases in others. It is concluded that the fig tree is a highly sought after plant in various industries, and in the feeding of cattle. Further studies on its nutritional effectiveness and how it is used in animal feeding are recommended for better valorisation of this plant.
