Características bromatológicas, fermentativas e população de leveduras de silagens de cana-de-açúcar acrescidas de ureia e aditivos absorventes de umidade

The research aimed to evaluate the use of additives on the fermentative and bromatological characteristics and the population of yeast of the sugarcane silage. The experiment was carried out in a complete randomized design with four replicates. It was tested different amount of additives added to the sugarcane silage at ensiling (based on the forage fresh matter) which were the...

Evaluation of sugar cane bagasse subjected to haying and ensiling

This work aimed to evaluate sugar cane bagasse from cachaça production, subjected to hay-making and ensiling. The experiment was conduced at Universidade Federal de Lavras, MG, using the completely random delineation (CRD), with seven treatment and three repetitions. The treatments were constituted of in natura sugar cane bagasse (INB), manually hayed and baled sugar cane bagasse...

Valor nutritivo do estilosantes Mineirão em função da correção do solo

The main expectation for using leguminous plants in pastures is improving animal production and reducing production costs. This research was carried out in a greenhouse, in order to evaluate the effect of two soil acidity correctives and P rates on P, Ca, Mg, Si, raw protein (RP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and in vitro dry matter digestibility...

Nodulação e produção de raízes do estilosantes Mineirão sob efeito de calagem, silicatagem e doses de fósforo

The objective of this research was to evaluate the effect of two soil correctives and P rates on nodulation, dry matter production, accumulation and content of nutrients in the roots of Stylosanthes guianensis (Aubl.) Sw. cv. Mineirão. The experiment was performed in a greenhouse. A randomized blocks design was used in a 5x2 factorial arrangement, with five P rates (50, 100, 200...

Alterações bromatológicas e fermentativas durante o armazenamento de silagens de cana-de-açúcar com e sem milho desintegrado com palha e sabugo

The chemical and fermentative changes of the sugar cane ensiled without or with (control) ground dried ear corn (GDEC) were evaluated during 100 days of storage period. The pH values, buffer capacity (BC), dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HM) ammonia nitrogen in relation to the total nitrogen (N-NH3/TN...

Effect of mineral protein suplements on live weight gain of grazing cattle

This work was carried out to evaluate the effect of supplements based on non-protein nitrogen (NPN) as: urea, amirea and multinutritional block, on live weight gain and cost analysis for cattle kept in pastures. During a period of 104 days(April to July 2004), 40 crossbreed bulls, uncastrated and initial average weight of 379kg, were allocated into 4 paddocks with Brachiaria...

Level of calcium and magnesium silicate in the yield of Marandu grass and Tanzania grass cultivated in one Quartzsandy Neosoil

This study was conducted in a greenhouse of the Soil Science Department at Universidade Federal de Lavras, Lavras-MG, with the purpose of evaluating the effect of the soil correction acidity, by the application of Ca and Mg silicate levels, in the production of grasses Brachiaria brizantha cv. Marandu and Panicum maximum cv. Tanzânia-1 cultivated in Quartzsandy Neosoil ortic. The...

Formas de aplicação de calcário nos teores de minerais da forragem do capim-tanzânia

With objective of evaluate the dry matter (DM) production, density, weight and height of tillers and leaf/stem ratio of tanzania grass (Panicum maximum Jacq. cv. Tanzania 1) in function of levels, placement and grainy lime an experiment was carried out in the field of Animal Science Department of Federal University of Lavras-UFLA, Lavras, MG. The experiment was constituted by...

Valor nutritivo de silagens de milho colhido em diversos estádios de maturação

This work evaluated the bromatologic characteristics of corn silages, ensiled at different maturity stages. It was used a split plot in time in a randomized block design, with four replicates. Cultivars evaluated were Geneze 2004, Agroceres 1051, Pioneer 30S40 and Pioneer 30F90 ensiled in the following maturity stages: 0% milk line kernels (SLL), reduction of milk line in 1/3 of...

Pasture structure and post-grazing herbage mass in pastures of elephantgrass cv. Cameroon and palisadegrass cv. Marandu

Two experiments were carried out to evaluate structural characteristics and crude protein concentration of Pennisetum purpureum cv. Cameroon and Brachiaria brizantha cv. Marandu under four rotational stocking rates. During the rainfall period, the studied stocking rates for both pastures were 3, 4, 5, and 6 steers/ha and in the dry period the stocking rates were 2, 3, 4, and 5...

Glyphosate e nitrgênio no controle de Brachiaria decumbens Stapf em capineiras estabelecidas

The objective of this experiment was to evaluate the efficiency of the use of the herbicide glyphosate associated with nitrogen fertilization in the control of Brachiaria decumbens Stapf in elephant grass stocking piles. The experimental design used was a randomized blocks with 17 treatments and three replications. The treatments were arranged in 4x4+1 factorial scheme, namely...

Influence of calcium:magnesium ratio in limestone on nodulation, dry matter yield and mineral composition of alfalfa

This study evaluated the effect of different Ca:Mg ratios on dry matter yield, mineral composition of alfalfa, and nodulation. A dystrophic Dark-Red Latosol (Oxisol) soil was used in the experiment. A randomized design was adapted with five Ca:Mg ratios (1:0; 1:1; 2:1; 3:1 and 4:1) at a recommended limestone dosage of 3.9 t ha-1. An additional treatment was included at a ratio of...
