On the efficacy, innocuity and residual depletion of flavomycin in confined steers
Neumann,Mikael; Souza,André Martins de; Falbo,Margarete Kimie; Bertagnon,Heloisa Godoi; Costa,Luísa da; Sidor,Fernando de SouzaAbstract Flavomycin is a non-ionophore additive little studied in finishing confined cattle. Therefore, this study aimed to evaluate the effectiveness of flavomycin on productive performance, ingestive behavior, carcass traits and biochemical parameters of steers finished in confinement. 32 whole steers, ½ Angus e ½ Nellore blood, from the same herd, with a mean age of 11 ± 1.5 months and initial body weight of...
Effect of storage time on the chemical composition of whole and grainless corn ...
Souza,André Martins de; Neumann,Mikael; Rampim,Leandro; Almeida,Eduardo Rodrigues de; Matchula,Angela Fernanda; Cristo,Fernando BragaABSTRACT The objective of this study was to evaluate the effect of harvesting corn at different maturity stages for silage production combined with four storage periods, considering nutrient loss and the chemical composition of silage of the whole plant and also of grainless plants. The experiment was performed in a completely randomized design with a factorial arrangement of six maturity stages of corn [reprod...
Substitution of dry corn grain by rehydrated and ensiled corn grain, finely or ...
Silva,Marlon Richard Hilário da; Jobim,Clóves Cabreira; Neumann,Mikael; Osmari,Milene PuntelABSTRACT We investigated the effects of corn grain, finely or coarsely ground, rehydrated and ensiled to 35% moisture in substitution of dry corn grain on performance of beef cattle in the feedlot. Forty non-castrated young Angus crossbred bulls with average age of 13±1.4 months and average initial body weight (BW) of 374±14 kg. The experiment was conducted in blocks by weight, and bulls were randomly assigned ...
Quality of sorghum silage in the feed-out period: evaluation of hybrids, silo l...
Neumann,Mikael; Horst,Egon Henrique; Restle,João; Almeida,Eduardo Rodrigues de; Souza,André Martins deAbstract This study aimed to evaluate the chemical and fermentation quality of silage from two sorghum hybrids in different layers of the silo feed-out face, as well as the interference of the aerobic exposure time of structured and/or unstructured silo face (after feed-out). The AG-2005E hybrid silage presented higher crude protein content and higher pH compared to hybrid AG-60298 (6.33% and 4.0 versus 6.06% a...
Effect of different double-sided plastic films on chemical and fermentation cha...
Cristo,Fernando Braga; Neumann,Mikael; Sidor,Fernando de Souza; Seller,Maria Eduarda Cozechen; Plodoviski,Daniel Corrêa; Carneiro,Everton LuizAbstract The objective of this study was to evaluate the efficiency of different double-sided plastic films on chemical and fermentation characteristics, dry matter digestibility, aerobic stability, physical and dry matter losses in corn silages stored in bunker silos. This was a completely randomized experimental design consisting of three treatments: DF110µm - double-sided polyethylene with 110 µm thickness; ...
Ruminal kinetics and degradability of energetic feedstuffs used in diets for ru...
Neumann,Mikael; Santos,Leslei Caroline; Askel,Eloize Jaqueline; Venancio,Bruno José; Pontarolo,Giovanna Bobato; Cristo,Fernando BragaAbstract This study aimed to evaluate energetic feedstuffs regarding chemical composition, in situ ruminal degradability of dry matter (DMD), ruminal kinetics and ruminal disappearance rate of dry matter. Seven feedstuffs (treatments) were evaluated: ground corn, ground oat, ground barley, wheat bran, soybean hull, malt root and corn germ, in a completely randomized design of four repetitions each. Two bovines ...
Effect of raising the cutting height in corn on performance and carcass traits ...
Hülse,Júlio; Neumann,Mikael; Leão,Guilherme Fernando Mattos; Souza,André Martins de; Santos,Leslei Caroline dos; Vigne,Gabriela Letícia DalaiAbstract This experiment was conducted to evaluate the effect of raising the cutting height of the corn plant destined to silage production, in relation to the dry biomass production and possible influence on the performance of confined lambs. The treatments tested were: SM20: Corn silage harvested at 20 cm height. SM80: Corn silage harvested at 80 cm height. Cutting at 80 cm from the ground reduced the dry bio...
Desempenho de novilhos confinados alimentados com silagens de diferentes híbrid...
Neumann,Mikael; Horst,Egon Henrique; Bueno,Antonio Vinicius Iank; Venancio,Bruno José; Santos,Leslei Caroline; Stadler Júnior,Edelmir SilvioObjetivou-se avaliar a ingestão de matéria seca, ganho de peso diário, conversão alimentar, digestibilidade e as características da carcaça de novilhos alimentados com dietas à base de silagens de dois híbridos de milho. Os tratamentos foram as silagens de milho provenientes dos híbridos LG6030 PRO e P30B39H. O delineamento experimental foi o inteiramente casualizado, com seis repetições, em esquema de parcelas...
Exogenous enzymes improve performance and carcass traits of feedlot cattle fed ...
Neumann,Mikael; Leão,Guilherme Fernando Mattos; Horst,Egon Henrique; Stuani,Osmair Flavio; Sangali,Cleiton Pagliari; Castilho,RicardoABSTRACT The objective of this study was to evaluate the effects of supplementation of two different enzymatic complexes, fibrolytic (NSPases) or amylolytic (EXP3066) enzymes, on growth performance, digestibility, behavior, and carcass characteristics of feedlot cattle. Thirty-six ½ Angus yearling bulls with an average initial weight of 391±5.0 kg were used in this experiment blocked by weight in a completely r...
Doses of enzyme complex in a high-energy diet on performance and carcass traits...
Vigne,Gabriela Letícia Delai; Neumann,Mikael; Santos,Leslei Caroline; Dochwat,André; Venancio,Bruno José; Heker Junior,Julio Cezar; Ueno,Robson KyoshiABSTRACT The objective of this study was to evaluate the production performance and carcass traits of feedlot steers fed a high-energy diet supplemented with doses of an enzyme complex (0, 2.5, 5.0, and, 7.5 g animal−1 day−1). Thirty-two ½ Angus ½ Nellore crossbred steers at an average age of 12 months and an average initial weight of 422 kg, were kept in a feedlot for 77 days. The roughage-free diet was compos...
