This study was carried out on a low-productive Brachiaria brizantha cv. Marandu pasture, mixed with Arachis pintoi cv. Belmonte (forage peanut), established 13 years ago in a Red-Yellow Latosol in Acre State, western Brazilian Amazon. The purpose was to evaluate the response of this pasture to different fertilizer combinations, aiming at identifying the nutritional factors responsible for the fall of pasture carrying capacity and for the reduced vigor of forage peanut. It was used a randomized complete block design, with […]

This study aimed to verify if the selection is influenced by partial observation of laying instead of observation of total daily posture. On the first state of analyses, through a Bayesian model, it was considered as analyzed characteristics the parameters of laying probability curve in a model of random effects with function of logistic connection. On the second stage of the procedure, it was obtained the estimatives of (co)variance components and genetic parameters. It was observed an overestimation of the […]

In Brazil, as in other countries, investments in research with horses are related to the objectives of the equine industry in the country. This study aimed to review the current literature with the purpose of assessing the latest scientific and technological development in horse’s production. Researchers are related to many areas as in production and management, genetics and breeding, nutrition and feeding, reproduction, medicine and surgery, diseases and health protection. There is still research in areas related to equestrian sports, […]

This research wants to lay emphasis on topics that historicize and rescue concepts, in addition, shows the relation between innovation and socioeconomic development resulted; reviews the legal framework to stimulate new innovation into Brazilian society; considers the definition and the entrepreneur university’s new paradigm; and finally, this research highlights the importance of teaching entrepreneur at universities, with straight society benefits. The results suggests that innovation is directly enrolled with a successful development of certain society, as well, is actually the […]

Because cultivation-based approaches to assess rumen microbiology assess only the minority of microbial groups and can miss opportunities to assess important functions, molecular-based approaches have flourished in microbial ecology and have been adapted to the rumen. Current approaches are described herein, specifically for a robust adaptation to nutrition studies or future opportunities. These included automated profiling techniques, density gradient gel electrophoresis, and future adaption of microarray or high-throughput sequencing technologies. Based on current knowledge, a more holistic approach is needed […]

It was evaluated in this work, crop yield, fermentative quality and nutritional value of the silage of cultivars of white (Avena Sativa L.) and black (Avena Strigosa Schreb) oats cut at two development stages. It was used an experimental randomized block design in a 4 x 2 factorial scheme, consisting of four oat cultivars (two cultivars of black oats: Aveia Preta Comum and UTFP 971; and two cultivars of white oats: ER 91156- 1- 2- 1 and SI 98105- b), […]

Fertility of dairy cattle is generally decreasing. Overall estrus detection efficiency in lactating dairy cattle is low, as expression of estrus is often compromised. Consequently, undetected estrus, low AI-submission rates, and long inter-breeding intervals are the main contributors to poor reproductive efficiency. Although failure to become pregnant is the most common reason for culling dairy cattle, pregnancy rates could be improved by increasing the AI-submission rate through increased estrus detection efficiency, timed insemination (Timed-AI), or timed embryo transfer (Timed-ET). In […]

Besides ensuring property and exclusive rights to holders of intellectual creation, intellectual property protection allows innovation and spread of knowledge, balancing the interests of the holder and the benefits to society. In this sense, Intellectual Property is strategic in the globalized and competitive world scenario, in which knowledge and innovation capacity play an important role in the development of a country. Therefore, aiming at intellectual property management with focus on innovation, it is necessary to encourage cooperation between the ICT […]

This study aimed to verify the existence of genetic variation among guineagrass cultivars regarding the effect of maturity on chemical composition and digestibility, and to classify the genotypes according to productive characteristics and nutritional quality. A randomized block design, with split- plots and three replications, was used. Dates of the cuts were considered as the plots, and the genotypes were considered as the sub- plots. Dry matter yield differed among the genotypes only at 90 days of growth, but the […]

Three experiments were carried out to evaluate the effect of probiotic on performance and intestinal health of chicks. It was used in the first experiment 300 fertilized eggs, in which water (placebo) or probiotic solution containing 10 mg of probiotic (Enterococcus faecium, Lactobacillus casei and Lactobacillus plantarum, 106ufc/g) were inoculated. In Experiment 2, it was evaluated the efficiency of probiotic (Bacillus subtilis) supply in the diet for chicks challenged with Salmonella Enteritidis on the first day of age. In the […]
