Histopatologia de fígado de codornas alimentadas com óleo de Moringa oleifera Lam em substituição ao óleo de soja

Abstract

The search for the threat of growth promoters for poultry feed, the search for substitute products that enable them to act on current antimicrobials, maintaining intestinal strength and the health of other organs, provide good nutrient absorption efficiency and good production rates. Probiotics, prebiotics, symbiotic and biological, and the prominent and close, are the perspective of alternatives to their positive action on animal health. Moringa is a fast growing plant with adaptation in tropical climates, it has several uses and it is in state of animal nutrition, having appeared some studies on the importance of vegetal nutrition, limiting the amino acids for the birds. Moringa oil also has therapeutic components, which are found largely under the health and performance of animals. The present study was about the effect of Moringa oleifera Lam oil on the liver of Japanese quails. A total of 120 birds with 18 weeks of age, distributed in a completely randomized design, housed in galvanized wire cages with dimensions of 33 x 30 x 18 cm (depth x width x height), equipped with drinking fountains and glass fountains were arranged on three floors, mounted on a ladder. The experiment was conducted at the Bird Research Laboratory (LAPAVE), located in the Animal Science Department of the Federal Rural University of Pernambuco. The experiment had five treatments, of 0; 0.5; 1; 1.5; 2.0% Moringa oleifera oil in the removal of soybean oil. At 36 weeks old, quail were sacrificed and the liver collected 4 birds from each treatment, ie 5x4 = 20 other organs, in order to look for signs of toxicity or improvement. The collected liver was preserved in 10% formalin solution, later these samples were taken to the animal histology laboratory where the histological slides were prepared. After the preparation of the laminae, a microscope was read where the lesions were described. We can observe that higher levels of soybean oil contributed to the presence of fatty liver, and that from 0.5% inclusion of Moringa oil we observed improvements in hepatic tissue, this effect is justified due to the presence of tocopherols, flavonoids and antioxidants present in the oil. With the present work we conclude that from the inclusion of 0.5% Moringa oleifera oil in Japanese laying quails feeding, it had an antioxidant effect against lipid peroxidation, increased ability to regulate membrane permeability of hepatocytes increasing its defense against the aggression of substances harmful to the organ that could cause greasy liver, thus also being able to highlight antinflammatory action with the increase of the activity of the cells of Kpuffer.
