Growth promoter based on soursop leaf in Hy Line Brown pullets: Production parameters and production costs

Over the years, poultry industry has used various types of promoters toimprove production; however, current trend is to eliminate growth that cause resistance in humans, for example, antibiotics European Union, there a need look natural alternatives are beneficial body and do not have negative impact on human health. The objective present study was evaluate productive parameters, pullets from one 16 weeks age, when using promoter feed, made soursop leaf ferment, as well todetermine its influence production costs. population consisted 200 Hy Line Brown pullets. A Completely Randomized Design (DCA), treatment control, were used. Production parameters recorded: weekly weight, feed consumption conversion, addition recording results showed between control no significant difference parameters. However, cost favored (S/16.87) compared (S/17.47), making use possible thenatural feeding birds.
