Orégano (Origanum Vulgare) desidratado nas rações de codornas japonesas

Abstract

The use of medicinal plants appears as an alternative to antibiotics. Oregano is a phytogenic that has several therapeutic properties, its beneficial effects are associated with its active ingredients such as carvacrol and thymol with antibiotic properties. The objective of this study was to evaluate the effects of dehydrated oregano at a concentration of 0.5% and 1% in the feeding of laying Japanese quails on performance parameters, egg quality, biometrics of the gastrointestinal tract and bones (tibia and femur) and biochemical profile of blood, liver and pancreas. 140 female quails were distributed in a completely randomized design with four treatments and five replications containing seven birds per cage. The treatments consisted of two control diets (corn and soybean meal) with and without antibiotics and two control diets with the addition of 05% and 1% of dehydrated oregano. The experimental period lasted 84 days. The inclusion of 0.5% and 1% dehydrated oregano did not affect performance, egg quality parameters, gastrointestinal tract and bone biometrics. There was a change in the biochemical profile with an increase in serum protein and a decrease in triglycerides and the enzyme glutamate oxalacetate transaminase.
