The objective of this study was to evaluate the efficacy of cleaning and decontamination procedures in liquid nitrogen tanks. We evaluated 151 canisters and 133 bottoms from 133 nitrogen tanks of companies or farms for the presence of bacteria and fungi. Samples were collected from the canisters and the bottom of tanks containing liquid nitrogen. Tanks were divided into Group 1 (G1): tanks decontaminated with 2% glutaraldehyde – Glutaron® II (n = 16 canisters in 8 tanks); Group 2 (G2): […]

This study was conducted to evaluate levels of inclusion of zeolite in diets for pigs on performance, carcass characteristics, blood and liver histopathological parameters of these animals in their growing-finishing phases. Eighty-four barrows from commercial hybrids of high genetic potential for meat deposition, with initial weight of 30.34±1.14 kg were distributed in randomized blocks design, with seven levels of adsorbent (0.0-0.0; 1.0-0.5; 1.0-1.0; 2.0-1.0; 2.0-2.0; 3.0-1.5; 3.0-3.0, respectively, on growing and finishing phases), six replicates with two animals per pen, […]

The research was conducted to evaluate two sources of ammonia (anhydrous ammonia-NH3 or urea) to preserve alfalfa (Medicago sativa L.) hay stored with high moisture. The following treatments were studied: A – Control: untreated hay (12 to 15% moisture); B – hay (24 to 27% moisture) treated with NH3 (1.0% of DM); C – hay (24 to 27% moisture) treated with urea (0.9% DM); D – hay (24 to 27% moisture) treated with urea (1.8% DM); E – hay (34 […]
