| Knowledge of information relative to the digestibility, intake and botanical and morphological composition of the diet is important in nutritional studies, since it provides the basis for understanding aspects related to the ingestive behavior and selectivity of animals. N-alkanes have been used successfully as markers in studies with many species of animals, particularly domesticated ruminants, most of the times as replacements for conventional markers as chromium oxide for example. However, for wild ruminants and non-ruminant animals information on this technique is still scarce and, as a consequence, its potential for use unknown. This review reports the use of this technique in studies of feed digestibility, intake and diet composition with wild... |

| The objective of this work was to evaluate aluminum tolerance of five genotypes of Urochloa decumbens (D24, CD24-2, CD24-27, CD24-45 e D62) and five genotypes of Urochloa ruziziensis (R30, R44, R46, R50 and R125) in hydroponic system. Uniform tillers were collected from these genotypes and transferred to two solutions: solution 1 (200 μM CaCl2, pH 4.2) and solution 2 (200 μM CaCl2 + 200 μM AlCl3, pH 4.2). Twenty-one days later, the roots of the plants were separated, stained and digitalized for analysis of the length and diameter of the main root. The experiment was conducted in a completely randomized design, in factorial (genotypes × doses) with three replications. A significant interaction occurred between genotype and dose for length and width of the... |

| The rapidly growing beef cattle herd of the Peoples Republic of China is largely carried as small numbers of animals on smallholder farms. These enterprises have traditionally focussed on cereal and vegetable crops. Limited plantings of specialised forages combined with a poor knowledge of ruminant nutrition by sm allholder farmers represent a serious challenge to establishing genuinely sustainable beef enterprises for this sector. Government policy to promote beef cattle production on smallholder farms is now focussing on the use of new forages and improved feeding practices. The paper draws on some economic insights from an Australian Centre for International Agricultural Research (ACIAR) project that is exploring options for integrating the planting and... |

| Neste trabalho, caracterizou-se a morfo-anatomia do caule e da folha de Brachiaria brizantha e B. humidicola, em três estratos, objetivando diferenciar tais estratos e espécies, bem como justificar, com estes parâmetros, a diferença de consumo que ocorre nessas espécies com o envelhecimento da planta. O experimento foi conduzido em casa de vegetação, utilizando-se vasos plásticos com areia esterilizada e recebendo solução nutritiva. Aos 70 dias após o corte de uniformização, cada planta foi dividida em três partes (estratos), coletando-se a folha mediana de cada estrato, separando-a em limbo e bainha foliar, e também o entrenó recoberto pela referida bainha. Para o estudo morfológico, foram mensurados a altura total das plantas, número total de folhas, nós... |

| Mechanical maceration enhances site and extent of digestion of low-moisture, low-quality forages. Four Holstein steers (172 ± 8 kg) with cannulas in rumen and proximal duodenum were used in 4x4 Latin square design to evaluate the process of mechanical maceration of sudangrass hay on the characteristics of ruminal and total tract digestion. Treatments consisted of a steam-flaked corn-based growing diet supplemented with 21 % forage (DM basis) as: i) wheat straw (Triticum aestivum, STRW), ii) sudangrass hay (Sorghum sudanense, SG), iii) macerated SG at intensity of 4,134 kPa (MAC600) and 4) macerated SG at intensity of 6,200 kPa (MAC900). All forages were ground to pass through a 3.8 cm screen before incorporation into complete mixed diets (21:79 forage to... |

| Forages are essential for the successful operation of animal production systems. This is more relevant to ruminants which are heavily dependant upon forages for their health and production in a cost-effective and sustainable manner. While forages are an economical source of nutrients for animal production, they also help conserve the soil integrity, water supply and air quality. Although the role of these forages for animal production could vary depending upon the regional preferences for the animal and forage species, climate and resources, their importance in the success of ruminant production is acknowledged. However with the increasing global human population and urbanisation, the sustainability of forage based animal production systems is sometimes... |

| A pecuária brasileira baseada em pastagens é uma das atividades econômicas mais importantes do Brasil, portanto são necessárias a manutenção e a ampliação de programas de melhoramento genético de forrageiras. Além de observar o desempenho agronômico do vegetal, é importante a determinação do seu valor nutritivo. Essa última característica é comumente determinada por análises bromatológicoas, mas, no entanto, existem fatores que limitam a ingestão e a digestão das forrageins que não são determinadas pelas análises convencionais, os quais são denominados de antiqualidade ou antinutricionais, os quais projudicam até mesmo a aceitabilidade da forragem pelos animais. Os fatores de antiqualidade são de natureza quimica ou estrutural, podendo ser determinados em... |

| The aim of this experiment was to evaluate, by means of the semi-automated in vitro gas production technique, fermentation kinetics of carbohydrates and degradability of dry matter (DM) and organic matter (OM) of diets containing oldman saltbush hay levels (8.4; 18.8; 31.2 and 48.3%) associated to forage cactus in natura. Pressure readings of the gases were done with a pressure transducer at 2, 4, 6, 8, 10, 12, 17, 20, 24, 28, 34, 48, 72 and 96h post-inoculation. The rumen kinetics was described by the following parameters: maximum potential of gas production, lag time and production rates of gas (k), fibrous carbohydrates (FC) and non-fibrous carbohydrates (NFC). It could be observed that the addition of oldman saltbush hay to the diets promoted a... |

| Abstract Mycotoxins are secondary metabolites produced by specific filamentous fungi that are common contaminants of agricultural commodities. These compounds are toxic to humans and animals, and they are a health problem worldwide. Mycotoxin-containing feeds can cause serious diseases in farm animals and substantial economic losses. Therefore, the objective of this study was to determine the occurrence and levels of six mycotoxins in three types of forage at retail in the state of Nuevo León, México. The hypothesis was that all types of forages were contaminated with at least one of the six mycotoxins analyzed. One hundred and twenty samples of alfalfa (Medicago sativa L.), sorghum [Sorghum bicolor (L.) Moench], and grass (Cenchrus ciliaris L.) used for... |

| Agricultural research in INIFAP (National Institute for Agricultural, Livestock and Forestry Research of Mexico) has been traditionally oriented to increase yields. Under this approach research objectives have been directed to obtain more kilograms of grains per hectare, more milk liters per cow, more meat per animal, etc. As national and international agricultural context has been changed, new approaches have been included and topics like environment and market trends are now incorporated to INIFAP's research activity. The market approach has been taken into account in an implicit way in some research projects of INIFAP. However, it is necessary to pay more attention to this topic because as it is known, consumers orient type and characteristics of goods... |

| The experiment aimed at determining repeatability coefficients for four methods (analysis of variance, principal components-correlation and covariance matrices and structural analysis), number of harvests necessary to increase accuracy and phenotypic stability of yield characteristics of accessions of Panicum maximum. The experiment was conducted in a completely randomized design with 35 genotypes and three replications. Five cuts were made and material was weighed and dried to obtain total, stem, leaf and dead forage dry matter yields. The repeatability coefficients in the different methods, for the evaluated characteristics, ranged from 0.1867 and 0.6583. The estimates of repeatability coefficients obtained for the evaluated characteristics by analysis... |
