Hematologia e histopatologia de codornas de corte alimentadas com farinha de barata de Madagascar

Abstract

The demand for alternative diets becomes critical in the poultry industry aiming to make the process of production more economical and sustainable. In this sense, the inclusion of insects in animals diet has been studied. We aimed with this study to evaluate the blood profile and histological traits of meat type quails fed diets with inclusion of different levels of Madagascar cockroach meal (Gromphadorhina portentosa). The experiment has a completely randomized design. Four levels of Madagascar cockroach (FBM) were used to feed the quails (0, 6, 12 and 18%) with six replicates each and 13 birds per experimental unit, in which two birds were randomly sampled for evaluations. The overall mean of erythrocytes for the four treatments was 3.97x103mm3. The general minimum and maximum values observed were 31.10 / 4.84; 13.60 / 16.10; 40.00 / 48.00; 91.30 / 138.70; 30,40 / 46,10 for erythrocytes, hemoglobin, hematocrit, mean corpuscular volume and mean corpuscular hemoglobin, respectively. The leukocyte values of the birds ranged from 16.5 to 17.7x103 / mm 3. The average values observed for eosinophils, lymphocytes and monocytes were 3.65%; 46.08% and 6.56%, respectively. There was no effect of inclusion of insect meal in the diet on the blood and histological evaluated parameters. The inclusion of Madagascar cockroach flour does not cause changes in blood and histological parameters of meat type quails up to 35 days of age. Thus, it is suggested that this ingredient can be used as an alternative food without prejudice to the health of the birds.
