| Testing the addition of an alkali (NaOH) in an air cleaner (Munters A/S) connected to a finisher pig unit during the summer resulted in an average odour reduction of 47%. The measurement days were spread over two batches of pigs (summer and autumn). The average odour reduction for the entire test period was 41%. The measurements taken during the autumn did not show a statistically significant odour reduction. Furthermore, the results showed that it was possible to reduce the emission of hydrogen sulphide by 53%. As expected, the levels of ammonia and carbon dioxide were not reduced. When using 100% air cleaning, the consumption of the air cleaner for two batches of finishers (30 – 110 kg) amounted to 355 L water and 2.4 kg 27.7% NaOH solution,... |

| In this study, we tested the performance and perspectives of four full-scale biotrickling filters based on Leca® (Light Expanded Clay Aggregates), a mechanically stable, non-degradable filter media, known to absorb odorous compounds such as H2S and methanethiol. The four filters varied in: filter thickness, carrying media, and the presence of dust filters. Biological Leca® filters were found to be capable of reducing NH3, H2S and odour by up to 96%, 80% and 78%, respectively. Clogging was observed to occur after approximately 100 days, but the installation of a dust filter successfully eliminated this problem. |

| Abstract The aim of this work was to determine the sensory quality (flavour, odour, tenderness, juiciness and overall acceptability) and physicochemical characteristics of meat from Santa Inês lambs fed with diets containing guava agroindustrial by-product (GAB). Was used samples of the longissimus lumborum of 40 entire males with an average slaughter weight of 32.0 kg, after approximately 105 days in a feedlot. Animals were randomly placed into four treatments (10 replicates per treatment) and fed with different levels of GAB (0, 20, 40 and 60%). Among the attributes examined, only odour was not influenced by the GAB. Inclusion of 40% GAB in diets (in place of corn) produced meat which satisfied consumer demands in terms of fresh colour, although with... |
