Chemical fractionation of carbohydrate and protein composition of corn silages fertilized with increasing doses of nitrogen Ciência Rural
Neumann,Mikael; Nörnberg,José Laerte; Leão,Guilherme Fernando Mattos; Horst,Egon Henrique; Figueira,Danúbia Nogueira.
ABSTRACT: The use of nitrogen fertilizers in corn crops for silage can improve both production and, theoretically, nutritional quality, especially carbohydrate and protein fractions, thereby optimizing animal production. Thus, the aim of this study was to evaluate the effect of increasing levels of nitrogen fertilization in carbohydrate and protein fractionation on the resulting corn silage (Zea mays L.). Nitrogen fertilization was carried out in the urea form (45-00-00) in V5 stage, at the following doses: T1: 0kg N ha-1; T2: 45kg N ha-1; T3: 90kg N ha-1; and T4: 135kg N ha-1. Crops were harvested at R4 stage and submitted to ensiling in experimental PVC silos. The chemical composition of the resulting silage was evaluated after silo opening. There was no...

Exogenous enzymes improve performance and carcass traits of feedlot cattle fed high-grain diet R. Bras. Zootec.
Neumann,Mikael; Leão,Guilherme Fernando Mattos; Horst,Egon Henrique; Stuani,Osmair Flavio; Sangali,Cleiton Pagliari; Castilho,Ricardo.
ABSTRACT 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 randomized design divided in three treatments: control, NSPases, and EXP3066. The basal diet was composed of 85% whole corn grain and 15% nucleus. NSPases increased average daily gain on days 63 and 84, and gain:feed ratio on days 42, 63, and 84. Total carcass weight and carcass daily gain were improved by 4.8% and up to 6.0% with EXP3066 and NSPases...

Performance and milk quality of cows fed triticale silage or intercropped with oats or legumes Scientia Agricola
Bumbieris Junior,Valter Harry; Emile,Jean-Claude; Jobim,Clóves Cabreira; Rossi,Robson Marcelo; Horst,Egon Henrique; Novak,Sandra.
ABSTRACT: The use of intercropped grass legumes provides a source of sustainable animal production as these vegetables contribute to an increase in forage yield by area, and substitute inorganic nitrogen and other components. The objective of this study was to evaluate the nutritional characteristics of silages and the yield and milk quality of Holstein cows fed triticale silages in monoculture or intercropped with either oats or legumes. The crops for silage production were triticale (TS), triticale in consortium with forage pea (TSP), and triticale in consortium with oats, forage peas and vetches (TSOPV). The silages showed no differences in dry matter content. The highest crude protein (13.06 %) and ethereal extract content was observed in TSOPV, but in...
