| Esta pesquisa foi conduzida com o objetivo de avaliar o efeito in vitro e in vivo do óleo de eucalipto (Corymbia citriodora) sobre o carrapato bovino (Rhipicephalus (Boophilus) microplus). Na experimentação in vitro, foi utilizado o grupo controle negativo e oito concentrações de óleo de eucalipto (0,5; 1; 2; 5; 10; 20; 50; 100%), em fêmeas ingurgitadas de carrapato. A eficácia de controle foi de 0; 30,5; 75,5; 91; 100; 100; 100; 100 e 100%, respectivamente. Para a experimentação in vivo, foram constituídos três grupos (controle negativo; óleo de eucalipto a 3,5% - nível estimado mediante análise de regressão, correspondendo a 95% de eficácia de controle do carrapato da pesquisa in vitro e amitraz a 0,025%), com dezoito vacas da raça Holandesa.

| ABSTRACT The aim of this study was to evaluate the ingestive behaviour of lambs or hoggets, finished in confinement on high-concentrate diets based on maize or sorghum grain. A total of 32 animals were used, 16 lambs (milk teeth) and 16 hoggets (2 teeth), which were distributed in a completely randomised experimental design and a 2 x 2 factorial scheme (two categories x two types of grain). In the categories under evaluation (lambs and hoggets), a significant difference (P≤0.05) was found for total chewing time, idle time and other activities (expressed in min/day and as a percentage), number of meals per day, time spent per meal and for the weight of dry matter or NDF ingested per meal (g/DM per REF and g/NDF per REF respectively). For the grain under... |

| ABSTRACT The aim of this study was to evaluate the effect of different levels of cottonseed (0, 100, 200, 300 and 400 g Kg-1) on the physical and chemical parameters of the meat of finishing lambs. Forty-five uncastrated male lambs were distributed in a completely randomised design with five treatments of nine replications. The pH values were not influenced by the levels of cottonseed. The lipid and ash content showed significant differences, but were not adjusted by the linear or quadratic equations. Losses during thawing increased, as did cohesiveness, and water activity and water retention capacity decreased as the levels of cottonseed in the diet rose. Tocopherols, cooking loss, toughness and chewiness were adjusted using quadratic equations. In the... |
