Efecto de la inclusión de zeolita (clinoptilolita) en ovinos en etapa de finalización: Respuesta productiva y energética de la dieta

Abstract: Borregos de pelo. Zeolita. Eficiencia energética. Dieta de finalización. resUMenEl objetivo de este estudio fue evaluar el efecto de la adición de diferentes niveles (0, 1,5, 3 y 4,5%) de zeolita en dietas integrales de finalización sobre la respuesta productiva y la eficiencia en la utilización de la energía neta de la dieta de ovinos de pelo. Para lo anterior, 40 ovinos machos ¾Katahdin × ¼Pelibuey (peso inicial = 32,28±2,34 kg) se asignaron a 20 corraletas (2 ovinos/corraleta, 5 corrales/tratamiento) alimen… Show more

“…ZEO replaced corn grain and soybean meal in equal parts. The ZEO source was calcic clinoptilolite with a purity of 92% (ZEO-SIL™; Grupo TCDN, Puebla, México); the level of ZEO used corresponded to the level for which better responses of growth performance and dietary energy in finishing lambs have been reported) [ 5 – 7 ]. The four dietary treatments were randomly assigned to pens within each weight block in a randomized complete block design.…”

“…The coefficient (0.276) was taken from the NRC [ 11 ], assuming a mature weight of 113 kg for Pelibuey × Katahdin male lambs. The observed dietary NE was calculated using the EM and EG values and the DMI observed during the experiment using the quadratic formula: x = (–b – √ b2 – 4ac)/ 2c, where: x = NE m , Mcal/kg, a = –0.41EM, b = 0.877 EM + 0.41 DMI + EG, and c = –0.877 DMI [ 7 ].…”

“…A study has shown that supplementing lambs with CTL increased muscle tissue deposition and decreased fat tissue deposition [ 15 ]. Additionally, an improvement in feed efficiency and ADG was reported [ 16 , 17 ]; the ion-exchange property of CTL favorably modulates ruminal fermentation, improving energy efficiency, which is reflected in animal growth performance [ 18 ]. However, the available results are conflicting; hence, more research is required in order to fully elucidate CTL’s response in ruminants.…”

Algo similar observó Vicente-Pérez et al…”
