| Este trabalho objetivou avaliar o comportamento ingestivo e o consumo de forragem de cordeiros em sistemas de terminação a pasto. Os tratamentos foram: cordeiros mantidos junto às ovelhas em pastagem de azevém sem suplementação; cordeiros mantidos junto às ovelhas na mesma pastagem, suplementados em creep feeding; cordeiros mantidos junto às ovelhas na mesma pastagem, suplementados em creep grazing com trevo branco. Foram realizadas três avaliações do comportamento ingestivo, verificando-se as atividades realizadas pelos animais (pastejo, ruminação, amamentação e outras atividades). Houve diferença (p < 0,05) no tempo destinado ao pastejo, à ruminação e a outras atividades, e os cordeiros não-suplementados tiveram maiores tempos de pastejo e ruminação e... |

| O objetivo deste estudo foi avaliar o comportamento ingestivo de cordeiros em pastagem de Tifton-85 (Cynodon spp.) em três sistemas de produção: cordeiros desmamados aos 60 dias de idade e mantidos em pastagem; cordeiros mantidos com suas mães em pastagem; e cordeiros mantidos com suas mães em pastagem e suplementados em creep feeding. O delineamento foi em blocos ao acaso com três repetições, utilizando quatro cordeiros-teste por repetição. Na pastagem, avaliou-se a altura, a massa, a composição morfológica e bromatológica da forragem. Na avaliação do comportamento ingestivo registrou-se, do nascer ao pôr do sol, o tempo despendido nas atividades de pastejo, ruminação, ócio, amamentação e alimentação no creep feeding. Avaliou-se, também, a taxa de bocados... |

| Understanding the changes in the total bud bank, and its contribution to community regeneration, in response to grassland enclosure to livestock grazing, is crucial for grassland management. Despite its importance, the contribution of the total bud bank and that of different bud types to community regeneration as a whole have been rarely explored. The vegetative offspring recruited from different bud types was investigated in grasslands having different enclosure durations to livestock grazing on a typical steppe of Inner Mongolia, China. Total vegetative offspring density was significantly higher (p<0.05) under continuous grazing than in fenced grasslands, but no significant changes were found among plots with different enclosure durations to livestock... |

| The objective of this study was to evaluate the correlations existing between nutrient intake and ingestive behavior of crossbred steers in the post-weaning phase on Brachiaria brizantha cv. Marandu, during the rainy period. Twenty-two steers were distributed into a completely randomized design, with two types of supplement and eleven replications, managed under rotational grazing, in a 6.5 ha area. Pearson’s Linear Correlation analysis was performed between the behavior variables and the performance variables values. The correlation coefficients were tested by the t test. The average daily gain (ADG) showed positive correlation with the times spent ruminating and eating at the trough and total chewing time. Positive correlation was observed between the... |

| The experiment was carried out to evaluate the patterns of defoliation in plants of various heights in the same pasture of Brachiaria decumbens cv. Basilisk under continuous stocking with cattle. Four plant heights were evaluated (10, 20, 30 and 40 cm) in the same managed sward, with mean height equal to 25 cm. A randomized blocks design was used, with two replications. Defoliation frequency increased linearly along with plant height in the same pasture. Defoliation intensity, number of defoliations in leaf blade and percentage of leaf blade grazed per tiller also increased linearly along with plant height. The defoliation interval decreased linearly according to plant height. The quadratic model was adequately fitted into grazing efficiency data, reaching... |

| This study aimed to evaluate the effects of oat or ryegrass over seeding on the productive characteristics and morphological composition of Tifton85 grass under continuous grazing. The three studied treatments were: Oat + Tifton85, Ryegrass + Tifton85 and Tifton85, distributed in a completely randomized design, constituting four replications of area per treatment. The Ryegrass + Tifton85 treatment presented a forage mass 27% superior to the Oat + Tifton85 treatment. The leaf percentage of Tifton85 was superior for the treatment Oat + Tifton85 (41%), while the percentage of stem + sheath was superior in the treatment Ryegrass + Tifton85 (64%). There was a higher percentage of Tifton85 leaves in the treatment Oat + Tifton85, while the Ryegrass + Tifton85... |

| Larval rearings were performed with seawater either freshly pumped or after storage in a pond. Concerning bacterial populations these waters were characterized by a high diversity, little sized bacteria whose few of them (1%) were cultivable on Zobell medium. In the tanks, the bacterial ecosystem was modified by the presence of antibiotics, larvae and algae: the diversity was lowered, the cellular volume was increased by a factor 2 to 5, 100% bacteria were cultivable and chloramphenicol resistant, and their metabolism changed. Taxonomic screening showed no differences among the two waters neither at the beginning nor at the end of the rearings. However, depending on the water (stored or not) differences were identified for bacterial physiology and... |

| Stocker cattle grazing warm season perennial grasses is an important economic activity in the southern Great Plains. Substantial increases in the price of nitrogen fertilizer is negatively affecting forage producers’ profitability. Two alternative nitrogen management systems that use annual and perennial legumes have been developed for bermudagrass pastures. The goal of the study is to determine if the legumes systems are more profitable than the conventional practice of applying synthetic sources of nitrogen. Results of the two-year grazing study show that the legume systems could not compete economically with the common practice. |

| Land-cover change has been identified as one of the most important drivers of change in ecosystems and their services. However, information on the consequences of land cover change for ecosystem services and human well-being at local scales is largely absent. Where information does exist, the traditional methods used to collate and communicate this information represent a significant obstacle to sustainable ecosystem management. Embedding science in a social process and solving problems together with stakeholders are necessary elements in ensuring that new knowledge results in desired actions, behavior changes, and decisions. We have attempted to address this identified information gap, as well as the way information is gathered, by quantifying the... |

| To rear lambs of the Ojalada breed, fed exclusively on mothers' milk until 5 weeks, three feeding systems were compared: a) ewes kept indoors and fed chopped straw plus concentrate (IND+CH+C), total mixed ration (TMR); b) ewes kept indoors and fed whole straw in the form of large bales plus concentrate (IND+W+C), TMR; and c) free-range grazing plus concentrate (GR+C; control group). Parameters related to ruminal fermentation (pH, NH3-N concentration and proportion of volatile fatty acids (VFAs)) in 40 sheep during a production cycle were monitored. The plasma concentrations of stress-related metabolites (i.e., glucose, lactate, phosphate, creatine kinase (CK), cortisol and non-esterified fatty acids (NEFAs)) during a production cycle and in 10 sheep during... |
