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 […]

Objetivou-se com este trabalho avaliar a produção e a composição do leite em vacas alimentadas com silagens contendo batata. Foram selecionadas 12 vacas: 9 delas com 50 a 70 meses de idade e 3 de 36 a 42 meses, lactantes, com peso aproximado de 550 kg. O delineamento experimental foi em três quadrados latinos 4 × 4, composto de quatro períodos experimentais e quatro tratamentos (silagens): silagens de milho (SM); capim-elefante (SC); capim-elefante com 7% de batata (SC 7%); e […]
