Performance and nutrient retention responses of broilers to dietary oxyhalogenic and ionic salts.
Two experiments were conducted to determine the effects of 2 ionic and antimicrobial mixtures on broiler performance and nutrient retention. In experiment 1, male broilers were fed 6 diets in a 2 x 3 factorial experiment (5 cages/diet, 9 chicks/cage) from 0 to 21d of age. Diets with 2 nutrient densities [normal industry diet (ND) and a low nutrient density diet (82% of ND)] and 3 ionic and antimicrobial mixtures [none (control) or 1 of 2 formulations containing different mixtures of ionic salts and oxyhalogenic compounds (sodium salts of chlorite, chlorate, chloride, borate, sulfate, bromide, salicylate, and hydrogen peroxide) at 4.4 mL/kg of feed (mix A and B)]. Birds fed mix B (568.6 g) were heavier (P < 0.05) at 21d of age than birds fed the control diet (501.7 g) and BW of birds fed mix A (536.1 g) did not differ from mix B or controls. Phosphorus and nitrogen retention from 18 to 20 d in birds fed mix B (78.05% and 82.23%, respectively) was greater (P < 0.05) than birds fed mix A (60.21 and 71.22%, respectively) and birds fed mix A had greater (P < 0.05) retention than birds fed the control diet (45.94 and 69.06%, respectively). In experiment 2, chicks were fed either 4.4 mL of mix B/kg feed, a diet with salinomycin and bacitracin, or a control diet. Birds fed the control or mix B diet had greater (P < 0.05) BW at 18 d than birds on the antibiotic treatment, whereas diet or nutrient retention differences were not present at 42 d of age. In conclusion, the ionic and antimicrobial mixtures improved performance and nutrient retention in young broilers but these did not last until market age.
