Effects of feed trough positioning height on growth performance, feed loss, feeding environment, and behavior of geese

Abstract

In the traditional feeding pattern of geese, the feed trough will be placed on the ground for a long time and hurts the living environment. This research aimed to investigate the effect of 4 different feed trough positioning heights on growth performance, blood parameters, feed loss, water consumption, feeding environment, and behavior of geese and determine the optimal trough positioning height for 28 to 70-d geese. A total of one hundred ninty-two 28-d male Yuzhou white geese were allocated randomly to 4 groups with 6 replicate pens per group according to the trough positioning height (on the ground [D], one-third [L], two-thirds [M], and the same height of geese's beak above the ground [H], respectively). The results show that the growth performance and blood biochemical parameters have no significant difference among groups (P > 0.05). The average daily feed loss and water consumption presented the lowest value in group H (P < 0.01). The hygienic condition index of the feed and feed trough increased as trough positioning height. Feed from group H had a higher cleanliness score than other groups (P < 0.001). The count of microbes (total bacteria, Staphylococcus aureus, and Escherichia coli) on the surface of the feed trough from group H was lower than other groups (P < 0.001). Geese from group H had shorter daily feeding and drinking time than other groups (P < 0.05). Overall, these data indicate the same trough positioning height with geese's beaks could lower feed loss, and water consumption and improve hygienic conditions without damage to growth performance and will be the optimal choice for geese.
