The effect of anti pecking devices and physical feed forms were studied on the performance of the Muscovy ducklings. A total of 300 Muscovy ducklings fed two ad libitum distributed diets: starter (1-42 d) and Finisher (43d -slaughtering age). The considered form of feed were: pelle-pellet (F1), crumble-pellet (F2), mash-mash (F3), for starter and finisher respectively; a no treted group (Tr1) and three anti pecking treatments were employed: 7 d.o. beak trimmed birds (Tr2), 21 d.o. beak trimmed birds (Tr3) and 21 d.o. blinkered birds (Tr4). For physical feed form, the results showed a significantly (P<0.01) highest growth rate (g.r.) of birds fed with f2 started diet (g.r./d/bird 21-42 d.: F1 =51g, F2 =56g, F3 = 52g). At the slaughtering age, g.r. of birds fed with the different forms did not show significantly differences . For antipecking devices the results showed a significant reduction of g.r. in the week following the debeaking treatmens.

Abstract

The effect of anti pecking devices and physical feed forms were studied on the performance of the Muscovy ducklings. A total of 300 Muscovy ducklings fed two ad libitum distributed diets: starter (1-42 d) and Finisher (43d -slaughtering age). The considered form of feed were: pelle-pellet (F1), crumble-pellet (F2), mash-mash (F3), for starter and finisher respectively; a no treted group (Tr1) and three anti pecking treatments were employed: 7 d.o. beak trimmed birds (Tr2), 21 d.o. beak trimmed birds (Tr3) and 21 d.o. blinkered birds (Tr4). For physical feed form, the results showed a significantly (P<0.01) highest growth rate (g.r.) of birds fed with f2 started diet (g.r./d/bird 21-42 d.: F1 =51g, F2 =56g, F3 = 52g). At the slaughtering age, g.r. of birds fed with the different forms did not show significantly differences . For antipecking devices the results showed a significant reduction of g.r. in the week following the debeaking treatmens.
