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 It is estimated that Salmonella causes one million illnesses in the United States annually, with 19,000 hospitalizations and 380 deaths. There are various serotypes of this bacterium, and the serotypes Typhimurium and Enteritidis are commonly isolated from outbreaks and, in most cases, present resistance to the antibiotics utilized in clinical medicine. One of the current theories to explain the emergence of bacterial resistance is the continuous use of antibiotics as growth promoters in animal feeds. Despite the lack of evidences that antibiotic growth promoters cause bacterial resistance, the poultry industry has explored strategies to reduce or to eliminate the use of antibiotic growth promoters in the production chain, including the... |

ABSTRACT The aim of this research was to evaluate the effects of adding calcium anacardate (ACa) as a source of anacardic acid to the diet of broiler chickens on the growth, quality and bone composition of the femur and tibia of the birds. A total of 840 male chicks, one day old, were kept in a completely randomised experimental design, with six treatments and seven replications of 20 birds. The following treatments were applied: a diet without the addition of growth promoter (GP), a diet with added GP and other diets with no GP and the addition of ACa at levels of 0.25, 0.50, 0.75 and 1%. The variables under analysis were the weight, length, diameter, Seedor index, and the resistance and deformity of the left femur and tibia of the birds. For bone... |
