- Effect of natural and synthetic pigments on growth performance, relative weight of some organs and cecal characteristics of young broilers R. Sánchez DiPalma F. Amaya Gonzalez R. Rodríguez Bertot R. Aroche Ginarte Y. Martínez Estudios Agrarios organ Broiler feed pigment growth promoter cecal microbiology To evaluate whether dietary supplementation with pigments (natural and synthetic) had a growth-promoting effect in broilers at the early stage (0-10 days), 480 one-day-old Ross 308® male chickens were randomly assigned to four treatments (four replicates and 30 birds). The experimental treatment consisted of a control diet and the supplementation with 1 % of Bixa orellana, 1 % of Murraya koenigii and 0.03 % of canthaxanthin. The experimental diets did not affect (P>0.05) the viability, however, Bixa orellana diet increased (P<0.05) the body weight compared to the other experimental groups, although this treatment did not change (P>0.05) the feed intake and feed conversion ratio in relation to the control diet. The treatments did not modify the relative weight of the gizzard, pancreas, and heart (P>0.05). However, the Bixa orellana and Murraya koenigii groups decreased (P<0.05) the relative weight of the proventriculus and cecum and the liver and abdominal fat, respectively. Furthermore, the canthaxanthin group increased (P<0.05) the relative weight of lymphoid organs and small intestine (P<0.05). Moreover, Bixa orellana diet decreased (P<0.05) the pH, total coliforms, Enterobacteriaceae and Escherichia coli in the cecum compared to the other diets, and the Murraya koenigii group increased (P<0.05) the population of lactic acid bacteria. Also, in this organ (cecum), yeast quantification decreased (P<0.05) due to canthaxanthin and the fungal population did not change among treatments (P>0.05). Dietary supplementation with Bixa orellana has a natural growth-promoting effect, as well as a marked antimicrobial effect against common cecal Enterobacteriaceae of broilers. 2025 otro 0864-0408 https://www.redalyc.org/articulo.oa?id=653781853003 https://www.redalyc.org/journal/6537/653781853003/ https://www.redalyc.org/journal/6537/653781853003/html/ https://www.redalyc.org/journal/6537/653781853003/653781853003.epub https://www.redalyc.org/journal/6537/653781853003/movil en http://www.redalyc.org/revista.oa?id=6537 Cuban Journal of Agricultural Science application/pdf Instituto de Ciencia Animal Cuban Journal of Agricultural Science (Cuba) Vol.59
