ABSTRACT This work aimed to evaluate the performance and egg quality of lightweight laying hens supplemented with a high biological value mineral, carbo-amino-phospho-chelates (CAPC), compared with inorganic minerals (sulfates), at different recommended values. A total of 320 Dekalb White hens, between 53 and 77 weeks of age, were distributed in a completely randomized design into two treatments, 10 replicates of 16 birds each. The treatments consisted of a reference diet formulated according to breed manual recommendations, in which one group was supplemented with a trace mineral source, CAPC (Cu, 8.6; Fe, 43.7; Mn, 56.4; Se, 0.34; and Zn, 43.7 mg/kg) and the other with a sulfate source, using the levels recommended in the breed manual (Cu, 8; Fe, 60; Mn,...

ABSTRACT The effect of additives used in the feed of broilers on anaerobic bio-digestion of poultry litter was evaluated. Four diets were used: NC: negative control; DFM: NC + 500 ppm direct-fed microbials (DFM) containing Bacillus subtilis and Bacillus licheniformis; ENZ: diet formulated with an enzyme blend (20 ppm phytase, 200 ppm protease and 200 ppm xylanase); DFM+E: ENZ + DFM. Substrates for the anaerobic bio-digestion were prepared with litter from each treatment, containing 4 % total solids (TS). These were used in 16 continuous bio-digesters with a 2 kg d−1 load, to determine the production and potential biogas production and composition during an 85-day period. Influent and effluent samples were collected for the amounts of TS and volatile solids...
