The weight gains, yield, and the quality of Andropogon gayanus cv were evaluated in a yellow Latosol of the experimental field of the Empresa Brasileira de Pesquisa Agropecuária (Embrapa-Rondônia), Porto Velho (96.3 m.a.s.l, 8graus 46' South latitude and 63graus 5' West longitude). Planaltina was submitted to different animal stocking rates (6, 12 and 18 sheeps/ha) Each treatment consisted on a variable area (lot) according to the animal stocking rate, evaluated in a continuous grazing system. Male sheared sheep, 5-7 months old, with an average initial weight between 19 and 20 k, were weighed every 28 days. During the dry season, the better gain of animal live weight (44.2 g/day) was found in the 12 sheep/ha stocking vs. the high load of 18 sheep/ha (25 g/day). In the rainy season, these gains were, respectively, 47 and 17 g/day. After 10-month evaluations, it was found that the most appropriate animal stocking rate was 12 sheep/ha; higher loads presented a significant reduction in the daily gain of live weight and in the pasture DM yield. |

Abstract: Anaerobic biodigestion is an appropriate alternative for the treatment of swine wastewater due to its biogas generation properties and the possibility of its application as a source of energy for heating or electricity. However, digestate can still contain high levels of turbidity, organic carbon and nutrients and must be correctly managed as a biofertilizer, or treated to avoid any impact on the environment. Considering this, electrocoagulation (EC) shows promise as a technology because of its ease of handling and high efficiency in effluent remediation. This study aimed to evaluate the performance of EC in a batch system in the treatment of swine wastewater digestate. The wastewater used in the treatment was sampled from a 10 m3 biodigestor effluent (digestate) located at Concórdia, Santa Catarina, Brazil. A batch-scale experiment was carried out to evaluate the following two variables: electrode distance (ED) and voltage applied (V). The removal efficiency levels (%) for the best operational condition (2 cm, 5 V) after 30 min were: 97 %, 98 %, 77 % and 10 % for color, turbidity, total organic carbon (TOC) and total nitrogen (TN), respectively. The EC batch system produced efficient results, underlining its promise as an alternative to be applied in the treatment of digestate. |
