A commercial blend of essential oil (EO) compounds was added to a grass, maize silage, and concentrate diet fed to dairy cattle in order to determine their influence on protein metabolism by ruminal microorganisms. EO inhibited (P < 0.05) the rate of deamination of amino acids. Pure-culture studies indicated that the species most sensitive to EO were ammonia-hyperproducing bacteria and anaerobi...

Maize silage has been used as a forage reserve strategy for critical periods or continuous use in animal feed. However, new genotypes and their potential must be identified. Thus, this study aimed to evaluate the of maize grain one off-season midwest region Brazil, under limited water frost, select them dual purpose (silage grain) using GT Biplot tool. The experiment was performed at Embrapa We...

The aim of this study was to evaluate life cycle environmental impacts associated with the generation of electricity from biogas produced by the anaerobic digestion (AD) of agricultural products and waste. Five real plants in Italy were considered, using maize silage, slurry, and tomato waste as feedstocks and cogenerating electricity and heat; the latter is not utilized. The results suggest th...

Most soil studies aim a better characterization of the system through indicators. In the present study nematofauna and soil structure were chosen as indicators to be assess soil health as related to agricultural practices. The field research was carried out on the two fodder cropping systems continuous maize (CM, Zea mays L.) and a 3-year rotation of silage-maize – silage-barley (Hordeum vulgar...

Biogas production from energy crops by anaerobic digestion is becoming increasingly important. The amount of biogas that can be produced per unit of biomass is referred to as the biomethane potential (BMP). For energy crops, the BMP varies among varieties and with crop state during the vegetation period. Traditional ways of analytical BMP determination are based on fermentation trials and requi...

Drought-tolerant maize hybrids currently are being marketed by several seed suppliers. Such hybrids were developed by phenotypic and marker-assisted selection or through genetic modification and tested by exposing these hybrids to various degrees of water restriction. As drought intensifies, crop yields and survival progressively decline. Water need differs among plants due to differences in ro...

Studies of soil Cd and Zn are often performed on sites that contaminated or have deficient conditions. Soil characteristics crop management could impact the mobility uptake Zn, even when considering unpolluted soils adequate levels. The concentrations these two metals were assessed in silage maize under five P fertilization treatments at growth stages low sufficient Pearson correlation coeffici...

We aimed to test the associative effects among forages, and between forage concentrates on in vitro digestibility of dry matter neutral detergent fibre using an artificial ruminal fermentation system. The study consisted two assays, which were evaluated three sugarcane, maize silage, Tifton 85 hay under incubation conditions (single feed or all feeds together a jar), sugarcane soybean meal and/...

This study's primary objective was to assess the quality parameters of fifteen different genotypes Serbian maize hybrids in order establish whether they were suitable for making high-quality silage ruminant feed. The study carried out as a two-year field experiment at Maize Research Institute Zemun Polje, Serbia. Laboratory analyses included yield structure examined hybrids, evaluation composit...

abstract in order to study of magnetic field and nanosilver effects on fodder maize in comparison to micronutrients fertilizers, an experiment was conducted at research farm of razavi research and technology institute in the year 2007. this experiment was done with 7 treatments based on randomized complete block design with four replications. treatments were including (t1) magnetic field and si...
