15. Comportamento ingestivo,consumo e digestibilidade de bovinos e búfalos alimentados com níveis crescentes de concentrado / Ingestive behavior intake and digestibilities of bovines and buffalos fed with increasing levels of concentrate
Objetivou-se avaliar o efeito da inclusão de concentrado em dietas de bovinos e bubalinos sobre o comportamento ingestivo, o consumo e a digestibilidade com peso vivo médio de 461,197,59 kg e 455,447,85 kg, respectivamente, distribuídos em dois quadrados latinos 4x4. Os tratamentos consistiram de diferentes níveis de concentrado (0; 24; 48; 72%). Cada pe

16. Características físico-químicas e sensoriais da carne de bovinos Nelore (Bos taurus indicus) alimentados com diferentes fontes de lipídeos e de selênio / Physicalchemical and sensorial characteristics of the Nellore bovine meat (Bos taurus indicus) fed with sources of fat and selenium
Objetivou-se determinar os efeitos de dietas contendo três fontes de lipídeos (semente de girassol, caroço de algodão e soja em grão "in natura") e duas de selênio (orgânico ou inorgânico) sobre o desempenho animal, características de carcaça e qualidade da carne de bovinos da raça Nelore (Bos taurus indicus). Foram utilizados 54 machos, castrados

17. Atividade de células entéricas de cordeiros recém-nascidos aleitados com colostro bovino e ovino / Enteric cell activity in newborn lambs fed bovine and ovine colostrum
O objetivo deste estudo foi avaliar o processo de aquisição de anticorpos em cordeiros recém-nascidos aleitados com colostro bovino e ovino, bem como a taxa de proliferação celular no epitélio intestinal. Este estudo contribui com informações sobre a aquisição de imunidade passiva nesta espécie, com o conhecimento do desenvolvimento e maturação

18. Evaluation in vitro and vivo of the cheese whey fermented by the consortium of bacteria Enterococcus faecium and Veilonella parvula in the feeding of ruminants / Avaliação in vitro e in vivo do soro de leite fermentado pelo consórcio de bactérias Enterococcus faecium e Veilonella parvula na alimentação de ruminantes
The industry of dairy products is gradually growing along the last years, standing out the cheese production. One of the by-products obtained of the production of the cheese is the cheese whey. This one presents high demand biochemistry of oxygen (DBO), that when being discarded in rivers or public sewers, it represents important environmental problem. Like

19. Nutritional evaluation of sugarcane treated with calcium oxide at different times of exposure to cattle / Avaliação nutricional da cana-de-açúcar acrescida de óxido de cálcio em diferentes tempos de amazenamento para bovinos
Were performed 4 experiments aiming evaluate the chemical composition and in vitro and in situ digestive kinetics of sugarcane treated with calcium oxide at different exposure times under nutrients intake and digestibility, performance, and ruminal parameters of Nellore heifers. The first experiment aimed to evaluate the effects of levels of inclusion and ex

20. Traceability of animal byproducts in quail (Coturnix coturnix japonica) tissues using carbon (13C/12C) and nitrogen (15N/14N) stable isotopes
Consistent information on meat products consumed by the public is essential. The technique of stable isotopes is a powerful tool to recover consumers' confidence, as it allows the detection of animal byproduct residues in poultry meat, particularly in quail meat. This study aimed at checking the presence of poultry byproduct mixtures in quail diets by applyi

21. Susceptibilidade de Digitonthophagus gazella (Fabricius : 1787) (Coleoptera: Scarabaeidae) aos reguladores de crescimento de insetos (IGRs) Diflubenzuron e Methoprene em UberlÃndia, MG
The Insect Growth Regulators are considered more selective than the conventional insecticides, are not toxic to mammals if used in the recomended dose and are easily degradable in environment. Diflubenzuron and Methoprene are IGRs from the chitin sinthesis inibithors and juvenile hormones analogs classes, respectively. These IGRs show comprovated eficience a

23. Nitrogen Balance and Endogenous Losses in Cattle and Buffaloes fed with increasing levels of concentrate / BALANÇO DE NITROGÊNIO E PERDAS ENDÓGENAS EM BOVINOS E BUBALINOS ALIMENTADOS COM NÍVEIS CRESCENTES DE CONCENTRADO
The work objectived to evaluate the plasmatic and urine urea concentrations, the balance of nitrogen compounds, and to estimate the protein requirements for maintenance. It was used the equations recommended by the American and British systems, in four bovine and four bubaline steers, with initial average weight of 461,197,59 and 455.447,85 kg for the bovine
