Effect of different mini‐volume colloid centrifugation configurations on flow cytometrically sorted sperm recovery efficiency and quality using a computer‐assisted semen analyzer
(Wiley, 2018-02)Straws of sex‐sorted sperm are usually packaged at a low concentration (e.g., ~2.1 × 106 sperm/ml) and cost significantly more than unsorted conventional semen from the same sire. In order to maximize the efficiency of ... -
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 ... -
Effect of genetic background on the stability of sunflower fatty acid composition in different high oleic mutations
(Wiley, 2018)BACKGROUND: The effect of genetic background on the stability of fatty acid composition in sunflower near isogenic lines (NILs) carrying high-oleic Pervenets (P) or high-oleicNM1mutationswas studied. Thematerialswere ... -
Effect of heat treatment and spray drying on lactobacilli viability and resistance to simulated gastrointestinal digestion
(Elsevier, 2012-10)Commercial probiotic bacteria are delivered mainly as frozen or freeze-dried cultures. However, spray drying is a lower cost technology that could be used for the production of probiotic cultures. In this work we aimed at ... -
Effect of high-pressure treatment on hard cheese proteolysis
(2016-06)The application of high hydrostatic pressure (HHP) treatment has been proposed to reduce the ripening time of cheese via modifications in the enzymatic activities or the substrate reactivity. Investigations on the effect ... -
