Efficacy of zinc lactate and Lactobacillus bulgaricus on nutrition and health of broiler chickens
Journal Title: Revista de la Facultad de Ciencias Agrarias. Universidad Nacional de Cuyo - Year 2023, Vol 55, Issue 2
Abstract
This investigation examined the effects of zinc lactate and Lactobacillus bulgaricus supplementation on the gastrointestinal microbiota of broiler chickens, analysing zootechnical, allometric, microbiological parameters and small intestine morphology. A total of 300 broiler chickens with an average initial weight of 47 g were distributed in four treatments in a completely randomised design. Treatments consisted of different zinc lactate and probiotic amounts added to the base diet. Chickens receiving the basal diet with organic zinc and L. bulgaricus showed a healthy response, remaining free of infectious agents for the 42-day study period. Treatment T1, with 30 mg of zinc lactate and 10 mg of probiotics per kg, showed improvements in weight gain, feed conversion, allometry, and intestinal health, as well as a healthy presence of gastrointestinal microbiota. Thus, the incorporation of zinc lactate (organic Zn) and probiotics based on L. bulgaricus into the basal diet of broiler chickens is an effective strategy to improve sanitary conditions and organic production of these species.
