Productive Response of Dairy Cows Fed with Different Levels of Totally Mixed Ration and Pasture
(2018-07)
Forty multiparous Holstein cows in early lactation (66 ± 19 days) were assigned to one of four treatments that consisted in different ratios of total mixed rations (TMR) and pasture at 100% TMR (T0), 75:25 (T1) 50:50 (T2) ...
Nanoparticle concentration vs. surface area in the interaction of thiol containing molecules: Towards a rational nano-architectural design of hybrid-materials
(American Chemical Society, 2019-04)
The effect of accounting for the total surface in the association of thiol-containing molecules to nanosilver was assessed using isothermal titration calorimetry, along with a new open access algorithm that calculates the ...
Towards a rational strategy for monitoring of microbiological quality of ambient waters
(Elsevier Science, 2012-06)
Water is one of the main sources of human exposure to microbiological hazards. Although legislation establishes regulatory standards in terms of fecal indicator bacteria to assess the microbiological quality of water, these ...
Rational design of antiangiogenic helical oligopeptides targeting the vascular endothelial growth factor receptors
(Frontiers Media S.A., 2019-03)
Tumor angiogenesis, essential for cancer development, is regulated mainly by vascular endothelial growth factors (VEGFs) and their receptors (VEGFRs), which are overexpressed in cancer cells. Therefore, the VEGF/VEGFR ...
Effect of type and feeding frequency of high-fibre feeds on intake, total tract digestibility and ruminal fermentation in beef steers fed a high-concentrate diet
(Csiro Publishing, 2019-10)
The inclusion of fibre in a total mixed ration (TMR) often has operational and economic constraints. The objective of the present study was to compare intake and ruminal fermentation of steers fed either a TMR or a diet ...
The pharmacokinetics of orally administered ivermectin in African elephants (loxodonta Africana): Implications for parasite elimination
(American Association of Zoo Veterinarians, 2009-03)
Loxodonta africana are susceptible to a wide variety of parasites that are often treated with the broad spectrum antiparasitic ivermectin (IVM) based on empirical knowledge. The objectives of this study were to 1) measure ...
Improving Concentration of Healthy Fatty Acids in Milk, Cheese and Yogurt by Adding a Blend of Soybean and Fish Oils to the Ration of Confined Dairy Cows
(Scientific Research Publishing, 2020-01-21)
Compared to pasture based sistems, milk produced in confined dairy systems is characterized by a high saturated fat (SF) content with a lower concentration of healthy fatty acids (FA) such as vaccenic (VA, trans 11C18:1), ...
Effect of ensiling a total mixed ration on feed quality for cattle in smallholder dairy farms = Efecto de ensilar una ración totalmente mezclada sobre la calidad nutritional para el ganado en pequeñas explotaciones lecheras
(Facultad de Ciencias Veterinarias, Universidad Austral de Chile, 2015)
The aim of this study was to assess the impact of ensiling a total mixed ration (TMR) on chemical composition, fermentation and sensory characteristics. Whole-plant corn (WPC) was ensiled alone, as a control, or in combination ...
Enrofloxacin-based therapeutic strategy for the prevention of endometritis in susceptible mares
(Wiley Blackwell Publishing, Inc, 2010-06)
Enrofloxacin (EFX) is often used empirically to prevent uterine infections in mares in order to improve efficiency on Commercial Embryo Transfer Farms. This study investigated the uterine distribution of EFX and its ...
Photophysics at Unusually High Dye Concentrations
(American Chemical Society, 2019-01)
The study of the interaction of light with systems at high dye concentrations implies a great challenge because several factors, such as emission reabsorption, dye aggregation, and energy trapping, hinder rationalization ...
