dc.description.none.fl_txt_mv The aim of this study was to determine the effects of four sources of commercial phytases on the performance and bone integrity of broilers from 1 to 28 days of age. Three hundred 1-day old Cobb 500 male chickens were distributed in 30 pens (10 birds per pen) and fed with the experimental diets for 28 days. The treatments were: T1, diet with adequate phosphorus (PAD); T2, phosphorus deficient diet (PDD); T3, PDD + phytase A (100 g/t); T4, PDD + phytase B (100 g/t); T5, PDD + phytase C (50 g/t) and T6, PDD + phytase D (50 g/t). Feeds and water were provided ad libitum. Body weight, body weight gain, feed consumption, feed conversion, and mortality were recorded weekly. At 28 days of age, 20 chicks per treatment were slaughtered to determine carcass and leg yield and tibia weight, plus bone moisture and ash content in the tibia. The results showed that the productive performance of broilers fed diets with normal levels of phosphorus (T1) were significantly higher (p<0.05) than chicks in the other treatments. Similarly, treatments T3 and T5 and treatments T4 and T6 presented similar responses, while T2 (deficient level of phosphorus) showed lower yields. Bone ash in all treatments, except for T2 (p<0.05), showed adequate levels. It was concluded that the productive responses of the birds that received diets deficient in phosphorus with the addition of phytase were lower than the level of response of the birds fed the diet with adequate level of phosphorus.
El objetivo del presente ensayo fue determinar el efecto de cuatro fuentes de fitasas comerciales sobre el rendimiento productivo y la integridad ósea de pollos de carne de 1 a 28 días de edad. Se utilizaron 300 pollos BB machos de la Línea Cobb 500 distribuidos al azar en 30 corrales en piso (10 aves por corral), alimentados durante 28 días con uno de los siguientes tratamientos: T1, Dieta normal en fósforo (DNP); T2, Dieta deficiente en fósforo (DDP); T3, DDP + Fitasa A (100 g/t); T4, DDP + Fitasa B (100 g/t); T5, DDP + Fitasa C (50 g/t) y T6, DDP + Fitasa D (50 g/t). El suministro de alimento y agua fue ad libitum. El peso vivo, ganancia de peso, consumo de alimento, conversión alimentaria y mortalidad se registraron semanalmente. A los 28 días de edad, 20 aves por tratamiento fueron sacrificados para determinar el rendimiento de carcasa, rendimiento de piernas, peso de tibias y, posteriormente, contenidos de humedad y ceniza en tibias. Los resultados mostraron que el comportamiento productivo de los pollos de carne alimentados con niveles normales de fósforo (T1) fueron significativamente superiores (p<0.05) al resto de tratamientos; asimismo, los tratamientos T3 y T5 y los tratamientos T4 y T6 presentaron respuestas similares, mientras que T2 (nivel deficiente de fósforo), mostró rendimientos menores. Las tibias de las aves de los tratamientos, con excepción del T2 (p<0.05), mostraron niveles adecuados de cenizas. Se concluye que las respuestas productivas de las aves que recibieron la dieta deficiente en fósforo con la adición de fitasas fueron menores que el nivel de respuesta de las aves alimentadas con la dieta normal en fósforo.
