Los sistemas ganaderos, en la Patagonia chilena, basan su producción pastoriles donde las praderas no presentan crecimiento durante el invierno. Una forma de suplir deficiencias es uso forrajes conservados, aunque generalmente cumplen con los requerimientos nutricionales animales. Entonces ganaderos utilizan suplementos que mejoran calidad nutricional dieta y esto eleva costo producción. El objetivo fue evaluar efecto inclusión bagazo cervecero húmedo (BCH) sobre rendimiento productivo...
Abstract. Despite the increased interest in hydrology of intermittent hydrological systems recent years, little attention has been given to tropical forest environments. We present a unique set hydrological, stable isotopic, geochemical, and landscape mapping information obtain mechanistic understanding streamflow generation an system 20 nested catchments (<1–159 km2) draining perennial streams rivers Chocó-Darien ecoregion, biodiversity hotspot, located Pacific lowlands northern Ecuador...
Mercury is a highly toxic element present in water, soil, air, and biota. Anthropogenic activities, such as burning fossil fuels, mining, deforestation, contribute to the presence mobilization of mercury between environmental compartments. Although current research on pathways has advanced our understanding risks associated with human exposure, limited information exists for remote areas high diversity fauna, flora, indigenous communities. This study aims deepen total sediments, fish, within...
The aim of the present study was to evaluate nutritional value, rumen in vitro fermentation, and situ degradation Brassica oleracea (L.) ssp. acephala (kales) Brassicanapus napobrassica (swedes) for winter use. Five varieties each brassica were used three field replicates randomized a complete block nested design. All forage harvested at 210 days post-sowing analyze chemical composition, gas production, volatile fatty acid (VFA) production dry matter (DM) crude protein (CP) degradability....
The objective of this work was to evaluate whether changes in time herbage allocation and mass (HM) (low (L) or medium (M)) modify the diurnal pattern urinary nitrogen (N) concentration ruminal ammonia (NH3) lactating dairy cows. Four Holstein-Friesian cows fitted with rumen cannula were randomly allocated one four treatments: 1) low morning (L-AM) (Access new after milking a 2000 kg DM/ha); 2) afternoon (L-PM) HM 3) (M-AM) 3000 4) (M-PM) DM/ha). A by Latin Square design treatments, cows,...
Livestock systems at Region Aysén del General Carlos Ibáñez Campo depend on forage conservation during the spring-summer season, generally with low nutritional quality to animal requirements. To reduce nutrient loss, additives are commonly used, being spent brewery yeast a potential additive. Therefore, study was carried out inclusion of two brewer's (Lager and Ale) as an additive in pasture mini silos compared commercial (SiloSolve MC™ Josilac grass™) silo without It observed that has...
Sugar-beet (Beta vulgaris L. subsp. vulgaris) pulp is a valuable by-product from the manufacture of beet sugar fresh which normally preserved in form silage. The aim present research was to evaluate effect adding homofermentative lactic acid bacteria silage additive during ensiling period on fermentation and quality sugar-beet (SB) animal performance dairy cows given restricted daily access pasture. Twelve Holstein à Friesian crossbred were assigned two groups according milk yield, body...
A study was undertaken to assess the effect of supplementation with sugar beet silage, corn or high-moisture on dairy performance, rumen, and plasma metabolites in cows under conditions restricted grazing spring. Eighteen multiparous Holstein Friesian cows, stratified for milk yield (39.4 kg/day ± 3.00), days lactation (67.0 22.5), live weight (584 kg 38.0), number calves (5.0 1.5), were allocated a replicated 3 × Latin square design. Treatments as follows: SBS (10 DM permanent pasture, 7 4...
