The objective of this study was to evaluate the efficiency of anaerobic digestion on the treatment of effluent from poultry slaughterhouse. The experiment was conducted at the Laboratory of Waste Recycling from Animal Production/FCA/UFGD. During four weeks, eight experimental digesters, semi-continuous models, were loaded and set according to the hydraulic retention time (HRT) of 7, 14, 21 and 28 days, and according to the solid fraction treatment, separated with 1 mm sieve or without separation. The average weekly production of […]

The objective was to evaluate the differences between distinct types of litter material and their combinations in the dynamics of degradation on the organic matter fractions and the quality of the final compound. The treatments were established according to material used as substrate for broiler litter: treatment 1 – rice husks; 2 – sugar cane bagasse; 3 – wood shavings; 4 – wood shavings + sugar cane bagasse; 5 – rice husks + sugar cane bagasse; and 6 – Napier […]

The objective of this study was to evaluate production and composition of milk from cows fed silages containing potato. Twelve females were selected: nine between 50 and 70 months of age and three between 36 and 42 months of age, lactating, with approximate weight of 550 kg. The experimental design consisted of 12 cows in three 4 × 4 Latin Squares, with four experimental periods and four treatments: silages of corn (CS); elephant grass (ES); elephant grass activated with 7% […]
