Gamma tocopherol (gT) exhibits beneficial cardiovascular effects partly due to its anti-inflammatory activity. Important sources of gT are vegetable oils. However, little is known to what extent gT can be transferred into marine animal species such as Atlantic salmon by feeding. Therefore, in this study we have investigated the transfer…
Six Holstein dry cows were used to evaluate the effect of a sensory additive (ProEfficient, Lucta S.A.) on eating behavior in a complete randomized design. Cows divided into 2 pens were randomly assigned to 2 treatments: control TMR or the same TMR supplemented with ProEfficient (PE) at a dose of…
Five hundred seventy Holstein dairy cows (280 primiparous and 290 multiparous; 194 DIM and 34.4 kg/d milk) from the commercial dairy farm El Trébol (Durango, México) were used to evaluate the effect of a sensory additive (ProEfficient, Lucta S.A.) on dry matter intake, milk production, and feed conversion efficiency under…
The objective of this study was to evaluate the effect of improving forage palatability on DM intake, milk production and composition, and rumen pH of lactating cows. Twenty one multiparous and 7 primiparous Holstein cows averaging 697 kg in body weight (SD ± 81), 54 DIM (SD ± 32), and…
Flavour cues present in amniotic fluid are used in mammals to find their mother early, but they are also useful for having contact with environmental flavours before birth. Three experiments have been performed to evaluate if piglets, during lactation and post-weaning, have the ability to prefer natural or artificial cues…
Introducción La percepción sensorial (gusto, olor, textura, y señales gastrointestinales) ayuda a los animales a relacionar los alimentos con su calidad nutricional, influyendo de este modo la capacidad que los mismos poseen de afectar el apetito. En particular, la estimulación gustativa tiene efectos directos sobre procesos neurofisiológicos que estimulan el…
Introducción En becerras, el destete es un momento crítico con impacto económico directo en la vida productiva del animal. Soberon et al. (2012) demostraron que por cada kg de crecimiento diario antes del destete la producción lechera corregida a 305 días de lactancia podía incrementarse entre 700 y 1000 kg…
We have shown that offering a variety of flavored feeds to sheep has the potential to change their feeding behavior and thereby enhance intake relative to a monotonous diet. The aim of this study was to assess whether the expected differences in feeding behavior displayed by sheep exposed to a…
Fostering newborn calves to consume solid feed before weaning can contribute to ensure proper rumen development, growth, and health during this critical phase. We hypothesized that conferring the starter feed sensorial properties (smell and taste) similar to the milk replacer (MR) may allow stimulating intake of solid feed before weaning.…
The symposium titled “Gut chemosensing: integrating nutrition, gut function, and metabolism in pigs” preceded the 12th International Symposium on Digestive Physiology of Pigs that was held in Keystone, CO, from May 29 to June 1, 2012. The objectives of the preconference symposium were to provide a comprehensive overview of the…
