- Abstract
Butyrate is an alternative to growth promoter antibiotics due to its action on pathogenic bacteria, intestinal villi and the immune system. The aim of this work was to determine the effect of several levels of sodium butyrate protected with fat in the diet of broilers on performance and carcass. A total of 160 birds housed in 16 pens were used. Pens were assigned according to a completely randomized design to one of four treatments: a negative control without growth promoter (WP); two in which the WP concentrate was mixed with sodium butyrate (3.5 and 7 g kg-1 of feed for treatments B3.5 and B7, respectively); and a positive control, where the WP concentrate was mixed with zinc bacitracin (Ba). The B7 birds presented higher live weight at 14 d and weight gain during the first week, compared to WP and Ba (p<0.05), but not compared to B3.5. The feed conversion index was higher for WP compared to B3.5 and B7 (p<0.05), but not compared to Ba. It is concluded that supplying fat-covered sodium butyrate to broilers in a level of 7 g kg-1 of the diet has a beneficial effect on the weight of the birds and the efficiency of the diet during the first weeks of life, even when it is compared to zinc bacitracin.
