Avaliação da inoculação de aminoácidos in ovo sobre a taxa de eclosão e qualidade de pintos de corte

Abstract

The effects of inoculation of amino acids in ovo were evaluated on birth weight, hatch rate and quality of day-old chicks. For this, 150 embryonated eggs were selected, with a completely randomized experimental design, with five treatments and 30 replicates (each egg considered as one plot). PBS + methionine (treatment 3), PBS + lysine (treatment 4), PBS + methionine (treatment 3), PBS + lysine (treatment 3) lysine (treatment 5). The eggs were placed in an automatic incubator and the nutrients were inoculated on the 18th day of incubation. For statistical analysis the data were submitted to statistical SAS program at a significance level of 5% and in the quality of the chicks performed the Kruskal-Wallis test also at asignificance level of 5%. The inoculation of amino acids methionine and lysine in ovo showed no significant difference (P> 0.05) among the treatments tested. The result was attributed to high concentrations of solutions inoculated in ovo, causing higher embryonic mortality. In this way, the inoculation of amino acids under the conditions performed was not significant for the evaluated variables.
