25. Effect of unsaturated fatty acid supplementation on digestion, metabolism and nutrient balance in dairy cows during the transition period and early lactation
The objective of this study was to evaluate the influence of unsaturated fatty acids in diets for dairy cows during the transition period and early lactation on intake, digestion and nutrient balance. Thirty-six multiparous and pregnant Holstein cows were randomly distributed to receive one of the experimental diets in the period from 35 days before the expe

26. Total digestible nutrient levels in supplements for finishing steers in the rainy season: nutritional characteristics and microbial efficiency
The objective of this study was to evaluate the effects of total digestible nutrient (TDN) levels in supplements on rumen pH, ruminal ammonia nitrogen concentration, intake and digestibility, nitrogen balance and microbial efficiency in beef cattle grazing on Marandu grass during the rainy season. The supplements comprised a mineral mixture, ground corn grai

27. Evaluation of nutrient excretion and retention in broilers submitted to different nutritional strategies
An experiment was carried out to evaluate the effects of different nutritional strategies on nitrogen (N), phosphorus (P) and calcium (Ca) balance and on copper (Cu), manganese (Mn) and zinc (Zn) excretion in broilers during the periods of 1 to 21 days and 1 to 46 days of age. Four hundred male Cobb-500 broilers were used. A randomized block experimental des

28. Variabilidade espacial e temporal das propriedades quÃmicas do solo e das folhas, qualidade do fruto e produtividade em pomar de laranja Monte Parnaso
The plant nutritional quality influences directly in juice quality. Therefore it is important the knowledge of its spatial and temporary variation in the orchard for a better application and use of the inputs, larger yield and quality of fruit. This way, input maps can be generated for the best use, providing larger yield and better quality of fruits, reduct

29. Influence of feed form and corn particle size on nutrient digestibility and energy utilization by young turkeys
A digestibility trial with 16 to 21-day-old turkeys was conducted to study the effects of feed form and corn particle size on the coefficient of total intestinal tract apparent digestibility of dry matter (DM), nitrogen (N), ether extract (EE), aparent metabolizable energy (AME) and aparent metabolizable energy corrected by nitrogen balance (AMEn). A complet

30. Evaluation of whey fermented by Enterococcus faecium in consortium with Veilonella parvula in ruminant feeding
The objective of this study was to evaluate the whey fermented by Enterococcus faecium in consortium with Veilonella parvula on the in vitro growth of ruminal bacteria and as a supplement in the cattle diet. In the in vitro experiment, a randomized design, with the following combinations was used: ruminal bacteria; ruminal bacteria and inactive whey; ruminal

31. Supplemental Ca2+ does not improve growth but it affects nutrient uptake in NaCl-stressed cowpea plants
The growth and nutrient assimilation was evaluated in CaCl2- and CaSO4-supplemented cowpea plants subjected to salt stress (75 mM NaCl). The salinity significantly reduced the cowpea vegetative growth. The addition of CaCl2 in the growth medium did not significantly affect plant growth, while for the CaSO4, the beneficial effects of Ca2+ were moderate. Salin

32. Tratamento com topiramato melhora a sensibilidade hipotalâmica à insulina em camundongos obesos / Topiramate improves insulin sigmalling the hypothalamus of mice on high-fat diet
Topiramate (TPM) is an anticonvulsant drug used for the treatment of epilepsy and prophylaxis of migraine. Weight loss is a frequently side effect reported in patients and animal models treated with TPM. In animal models topiramate may increase levels of hypothalamic corticotropic-releasing hormone (CRH), which is an anorexigenic neuropeptide and may decreas

34. Deficiência de tiamina e isolamento social afetam aspectos do comportamento motor e níveis centrais de GABA e glutamato
The main phenomenon approached in this study is the motor behavior, evaluated after two different types of environmental stimuli, the consumption of diet deficient in B1 vitamin and/or social isolation. The B1 vitamin, thiamine, is an essential nutrient for the nervous tissue. In previous studies, our research group has shown that the maternal thiamine defic
