| ABSTRACT The objective of this study was to evaluate the energetic values of dry residue of cassava (DRC) and the effects of its inclusion in broiler diets on performance, intestinal morphometry, protein and fat deposition rate, and carcass and cut yields. In experiment I, two metabolism trials were carried out from 11-21 and from 31-41 days of age. The birds were distributed in a completely randomized design and DRC was included at levels of 10, 20, 30 and 40% in the basal diet. In experiment II, 980 male chicks were distributed in a completely randomized design with seven treatments (0; 2; 4; 6; 8; 10; 12% DRC) and seven replicates. DRC levels did not influence (p>0.05) the energetic values. From days 1-7, weight gain (WG) had a linear adjustment, and... |

| ABSTRACT This experiment was conducted to evaluate the effect of crude glycerin at differing inclusion levels on performance and carcass characteristics of broilers and litter moisture. 960 broilers of 21-42 days of age were used in a completely randomized design with six crude glycerin inclusion levels (0, 3, 6, 9, 12, 15%), with eight replicates containing 20 broiler chickens per experimental unit. There was a quadratic effect (p<0.05) for weight gain, feed intake and feed:gain ratio from 21 to 42 days of age. Higher levels of crude glycerin in diets increased (40.24%, p<0.05) the litter moisture and reduced (6.04%, p<0.05) the viability of of the birds. There were no effects (p>0.05) on carcass yield, breast, or liver percentages. However,... |
