| A pecuária de corte brasileira é um dos pilares do agronegócio do país. Em 2013 o valor bruto da produção de carne foi de R$ 51,1 bilhões, atrás apenas do complexo soja (BRASIL, 2014). A cadeia produtiva da carne movimenta R$ 167,5 bilhões por ano, gerando aproximadamente 7,0 milhões de empregos (NEVES, 2012). Em 2013 o país produziu 9,5 milhões de toneladas de carne bovina, dos quais cerca de 7,2 milhões de toneladas foram destinadas ao mercado interno (CONAB, 2014). A pecuária leiteira é uma das atividades mais tradicionais do meio rural brasileiro e, de acordo com o último censo agropecuário (IBGE, 2006), existem no Brasil aproximadamente 5,2 milhões de estabelecimentos rurais dos quais 25% produzem leite, envolvendo cerca de cinco milhões de pessoas.

| A maioria das plantas forrageiras da caatinga apresenta baixos indices de digestibilidade "in vitro" da materia seca (DIVMS). A dieta que sao submetidos os doadores de liquido ruminal, parece interferir na fermentacao. Visando testar o efeito da dieta do doador de inoculo na fermentacao "in vitro", foram utilizados bois submetidos a diferentes dietas: caatinga e feno capim-bufel. Na segunda incubacao as dietas dos bois foram invertidas. O inoculo da caatinga, elevou significativamente (P< 0,01) a DIVMS da jurema-preta (27.02 vs 31,88) e da leucena (63,33 vs 65,35) e reduziu a DIVMS do feno de buffel (60,18 vs 58,16). A elevacao dos valores da DIVMS da jurema provocada pelo inoculo da caatinga, parece nao ter sido significativo do ponto de vista... |

| While the significant ecosystem damage caused by invasive weeds has been well documented, the economic impacts of specific invasive weed species are poorly understood. Yellow starthistle (Centaurea solstitialis L., hereafter YST) is the most widespread non-crop weed in California, resulting in serious damage to forage on natural range and improved pasture. A survey was administered to California cattle ranchers to investigate YST infestation rates, loss of forage quantity and value, and control or eradication efforts. The results were used to estimate county-wide economic losses for three focus counties, as well as state-wide economic losses, due to YST in California. Total losses of livestock forage value due to YST on private land for the state of... |

| ABSTRACT: Parthenium is an important weed which poses severe threats to yield and quality of sorghum and many other summer season crops, worldwide. As in other field crops, parthenium also reduces yield and quality of forage plants in forage crops so it should be controlled in forage and fodder crops. Parthenium control efficacy of five herbicide treatments (including dicamba at 304.5 g a.i. ha-1 (full rate) alone, dicamba at full rate + 1% ammonium sulphate, dicamba at full rate + 2% ammonium sulphate, dicamba at 75% rate + 1% ammonium sulphate and dicamba at 75% rate + 2% ammonium sulphate) was tested in field trials for two consecutive years (2013 and 2014). One manual hoeing three weeks after crop emergence was also performed as a treatment and weedy... |

Effect of genus and growth stage on the chemical and mineral composition of tropical grasses used to feed dairy cows. Cien. Inv. Agr. 43(3): 476-485. In tropical production systems, dairy cows are rarely supplemented with minerals, which often lead to mineral imbalances. Grasses grown together in the same soil type and sampled at the same growth stage can vary widely in chemical and mineral composition; therefore, the objective of this study was to characterize the chemical and mineral composition of Urochloa spp., Megathyrsus spp., and Andropogon spp. at three different stages of growth in the same soil type. The content... |

| Abstract Mombasa grass is very demanding and responsive to soil fertility. The objective of the present study was to evaluate forage production and the correlation among crude protein and the green color index of leaves of Megathyrsus maximum cultivar Mombasa in function of nitrogen levels. The study was conducted using 5 dm-3 pots in a greenhouse at the Universidade Estadual Paulista - UNESP, Jaboticabal, São Paulo. The experimental design consisted of randomized blocks with five treatments and four replications. Treatments were nitrogen rates (0, 62.5, 125, 250 and 500 mg dm-3 of N), corresponding to 0, 125, 250, 500 and 1000 kg ha-1 of N. We evaluated the production of grass dry matter, the green color index, the accumulation of nitrogen and crude... |

| Application of calcium silicate (SiCa) as soil acidity corrective was evaluated in a Rhodic Hapludox soil with palisade grass conducted under pasture rotation system with different grazing intensities. Experimental design was complete randomized blocks with four grazing intensities - grazing intensities were imposed by forage supply (50, 100, 150 and 200 kg t-1 of DM per LW) - in experimental plots with four replicates and, in the subplots, with seven doses of calcium silicate combined with lime: 0+0, 2+0, 4+0, 6+0, 2+4, 4+2 and 0+6 t ha-1, respectively. In the soil, it was evaluated the effect of four levels of calcium silicate (0, 2, 4 and 6 t ha-1) at 45, 90, and 365 days at three depths (0-10, 10-20 and 20-40 cm) and at 365 days, it was included one... |

| ABSTRACT: Vis-NIR-SWIR reflectance spectra of leaf samples, collected in the laboratory, allow the calibration of predictive models to quantify their physicochemical attributes in a practical manner and without producing chemical residues. This technique should enable the development of management strategies for intensification of pasture use. However, spectral analysis performed in the laboratory may be affected by the deterioration of plant material during transport from the field to the lab, so storage methods are necessary. This research aimed to evaluate the effects of different storage methods on the spectral response of Mombasa grass leaves. Three methods were evaluated: (i) artificially refrigerated environment, (ii) humid environment, and (iii)... |
