| The objective of this experiment was to evaluate the effects of a diet containing canthaxanthin and 25-hydroxycholecalciferol (25-OH-D3) on the production and reproductive performances of Cobb 500 broiler breeders aged 53 to 61 weeks. The study included 36,000 Cobb 500 female and 3,600 male broiler breeders aging 51 weeks. The birds were housed in three poultry houses divided into four plots, totaling 12 experimental units each containing 3,000 females and 300 males. The birds received the following treatments: control diet (without the studied additives) or the control diet with the addition of 60mg kg-1feed of 25-(OH)-D3 and canthaxanthin feed (6mg of canthaxanthin and 2,760,000IU of 25-(OH)-D3 per kg of feed) per the supplier's recommendations.

| Abstract: The objective of this work was to determine the correlation of the physical attributes of corn and the mycotoxins present in its grains with the severity of tongue lesions in broiler breeder roosters. The occurrence of the aflatoxin, vomitoxin, zearalenone, T-2 toxin, and fumonisin mycotoxins was detected in the corn grains used in the feed formulation for breeder chickens. The percentages of moisture and broken grains were positively correlated (Pearson’s correlation) with the presence of aflatoxin. Milder lesions (grade 1) are positively correlated with aflatoxin and negatively correlated with fumonisin, and the most severe lesions (grade 3) are positively correlated with vomitoxin, fumonisin, and T-2 toxin. |

| Avaliou-se o desempenho da progênie de matrizes de corte que consumiram aflatoxinas e glucomananos esterificados como adsorvente por quatro ou oito semanas. Foram conduzidos dois experimentos no período de 1 a 21 dias de idade. Em cada estudo foram utilizados 160 machos de 1 dia provenientes de matrizes alimentadas com dietas contendo aflatoxinas e adsorvente. Em ambos os ensaios, foi adotado um delineamento experimental inteiramente casualizado para avaliação de cinco dietas (tratamentos), cada uma avaliada com quatro repetições de oito aves. Nas dietas fornecidas às matrizes, as aflatoxinas foram adicionadas nos níveis 0; 0,500; ou 0,750 mg/kg de ração em combinação ou não a 0,10% de adsorvente. Os dois ensaios com frangos de corte foram conduzidos em... |
