Resumo: | ABSTRACT Salmonellosis is a globally important zoonosis, and Salmonella Heidelberg is one of the most prevalent serovars in poultry production worldwide, as well as in food poisoning cases. Antimicrobial drugs were previously widely used to face health challenges in animal production; however, since their ban as performance enhancers, many alternative strategies have been proposed. One of these strategies is the use of plant extracts, such as those containing the alkaloids benzophenanthridine and protopine. These compounds have antimicrobial, anti-inflammatory, immunomodulation, and nutritional effects. The objective of the present study was to evaluate the effects of the supply of a product containing benzophenanthridine and protopine (Sangrovit(r)WS 100 g/1000 L of drinking water) to broilers during different rearing periods 1-21, 1-6 and 6-21 days of age challenged or not with Salmonella Heidelberg at six days of age. There was no effect of the product on the performance, jejunal morphometry, cecal goblet cell counts, or control of Salmonella spp. in broilers challenged or not with Salmonella Heidelberg. However, the group receiving the alkaloids from 1 to 21 days of age, compared with the control group, presented a numerical difference of 28 points in productive efficiency index, which directly impacts live production cost of live broiler, representing savings of R$ 0.11/kg of meat produced.
