Human activities are contributing to Global Climate Change through the production of Green House Gases (GHG), which result in increased air, land and ocean temperatures and extreme changes in precipitation in regions of low and high rainfall. The most important GHG’s are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). It is estimated that 18 % of the annual GHG emissions come from different types of livestock and that 37% of CH4, with higher global warming potential (23) relative […]

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 […]

Sheep and cattle farmers need pastoral systems that are more productive and environmentally sustainable. The role that high feeding value herb and legume forage species can play in the farms of the future is highlighted. It is shown that species such as chicory (Cichorium intybus), plantain (Plantago lanceolata), red clover (Trifolium pratense) and white clover (T.repens) can provide live weight gains in lambs that are 70% greater than those from perennial ryegrass (Lolium perenne) based pastures. A case for replicated […]

The objetive in this experiment was to evaluate carcass and beef quantitative and qualitative characterstics from young bulls, slaughtered at 14-16 months of age and fed diets containing different concentrate levels. It was used sixteen Charolais- Nellore crossbreed non-castrated young bulls and fed diets containing 22; 40; 59 or 79% of concentrate. The animals were complete randomly distributed, with four replicates per diet. Initial age and body weight of the animals were 9.32 months and 192.44 kg, respectively. The animals […]

The objective of this study was to evaluate tissue composition of loin and leg and fatty acids profile of the meat of lambs in four finishing systems: (1) lambs weaned around 40 days of age and kept in ryegrass pastures until slaughter; (2) lambs kept with their dams in the same pasture until slaughter; (3) same treatment of (2), but daily supplemented with 1% of the body weight in creep feeding; (4) lambs weaned at 40 days of age and […]

The aim of this work was to evaluate the effect of replacing concentrate by wet brewer grain on the intake and digestibility of nutrients in goats. It was used five Boer x Saanen crossbreed goats and five Saanen goats randomly distributed in two 5 x 5 latin squares. The diets were composed of 40% of Tifton hay and the other 60% were composed of 0, 25, 50, 75 or 100% of wet brewer grain replacing the concentrate. The intake of […]

It was aimed to evaluate in this work the effects of physical characteristics (density, solubility, average particle size and water holding capacity) on in situ effective degraded fraction of the dry matter of soybean meal, canola meal, peanut meal, and cottonseed meal. It was also evaluated the passage rate of solids using four Santa Ines castrated wethers cannulated in the rumen. Samples with 100 g of each protein meal marked with sodium dichromate were put in the rumen and kept […]

It was aimed to evaluate the effect of inclusion and times of sugar cane exposition to whitewash on intake and total and partial digestibility of nutrients and ruminal parameters and to compare titanium dioxide and chromium oxide as markers to estimate fecal dry matter excretion and dry matter abomasal flow. It was used six rumen and abomasum cannulated Nellore females, with average body weight of 250 ± 19 kg, distributed in an incomplete 6 x 6 latin square design. The […]

This study was developed to evaluate the ingestive behavior of beef cattle finished in feedlots with different concentrate levels in the diet. Sixteen bulls fed 22, 40, 59, or 79% of concentrate in the diet were assigned to a complete randomized design, with four replicates each. The supplied diets were isoproteic and the roughage used was corn silage. Data collection was carried out during the finishing period, with a total of six days. The time given to food intake, rumination, […]

The objective of this work was to evaluate the quantitative characteristics of carcasses of Moxotó and Canindé goats finished in feedlots and fed diets of two levels of energy. It was used 40 castrated young goats, 20 from Moxotó breed and 20 from Canindé breed, each one with an average body weight of 15.2 kg. The animals were fed with diets containing 2.20 and 2.71 (Mcal/kg DM). The experimental period lasted 86 days. There was no difference among the barometric […]
