Acción de la apitoxina en la biosíntesis de cortisol y su efecto en el comportamiento productivo de pollos broiler

As an alternative organic production, it was proposed as an objective, to demonstrate experimentally that the apitoxin influences the biosynthesis of corticosteroids in the organism of chickens for fattening. Because cortisol increases levels of amylase in blood and leptin, accelerating carbohydrate hydrolysis and fat lipolysis, performance and response to the ongoing challenge of intensive poultry production can be improved. In this research, a completely randomized block design (DBCA) was used, with 4 treatments and 3 replicates. Test groups received apitoxin in drinking water during: the first, third and fifth weeks. The results obtained show a higher concentration of cortisol for the test groups with 27% in males and 42% in females more than in the control group. The zootechnical indicators presented better performance in favor of males, followed by females, who received the treatment in the following order: 7.2% and 6.7% of greater body weight; 119.9 and 5.8 g of lower feed intake; and better efficiency in feed conversion with 0.19 and 0.12 points for females and males respectively.
