| ABSTRACT This study was designed to determine the effect of a combination of propionic-acetic acid on body weight, the relative weight of some organs, lactic acid bacteria, and intestinal pH of neonatal broilers. A total of 60 1-day-old Ross 308® broiler chickens were randomly placed in metabolic cages to two treatments, three replicates, and ten birds per replicates. The treatments consisted of a control diet (CD) and CD + 0.03% of propionic acid and acetic acid in the drinking water at a rate of 4 ml/L of water. The combination of organic acids depressed the body weight in neonatal broilers (p<0.05) and increased the relative weight (p<0.05) of gizzard, proventriculus, small intestine, and liver; also acidified the cecum with a significant decrease... |

| ABSTRACT The aim of this study was to determine the effects of dietary supplementation with red algae powder (Chondrus crispus) on the growth performance, carcass traits, lymphoid organ weights and intestinal pH y in broiler chickens. A total of 300 1-day-old B34 line male broiler chickens were randomly allotted to three treatments, four replicates per treatment and 25 birds per replicate. The experimental treatments consisted of a basal diet (T0) and dietary supplementation of 0.30 (T2) and 0.40% (T2) red algae powder. Body weight at 1, 21 and 32 days did not show significant differences (p>0.05) among treatments. At 21 days, T1decreased (p<0.05) the feed intake and feed conversion ratio. However, from 22 to up to 32 days, these productive... |
