The technical practicability of high temperature leaching process using willemite concentrate as the materials was developed in study for extracting base metals. factors affecting rates zinc, iron, and silica from were investigated, optimized maximum zinc extraction minimum iron dissolution to meet needs solution purification. Under studied conditions (413 K, 0.81 mol/L sulfuric acid, duration ...

Published data on the effects of essential oils (EO) on in vivo nutrient digestibility in sheep are contradictory. In 2 experiments, the effect of thymol and carvacrol on nutrient digestibility was studied in sheep fed with high (70%) or low (52%) concentrate diets, using incomplete Latin Square designs. The essential oils were mixed with the concentrate portion of the diet at the rate of 0.0, ...

The present study was carried out to establish knowledge of consequence for setting up guidelines of importance for production of competitive organic pork of high quality. Performance and meat quality characteristics were compared between three organic pig production systems based on indoor housing with access to an outdoor area and a Danish conventional indoor system including 100% concentrate...

The influence of fiber content of hay (low-fiber 47% NDF and high-fiber 62% NDF of DM) and concentrate level (high 50% and low 20% of ration DM) on chewing activity, passage rate and nutrient digestibility were tested on four restrict-fed (11.1 to 13.7 kg DM/d) Holstein cows in late lactation. Aspects of ruminal fermentation and digesta particle size distribution were also investigated on two r...

PURPOSE The mechanism underlying the decline in milk quality during periods of feeding high-concentrate diets to dairy ruminants is not well documented. The aim of this study was to investigate the metabolic changes in the liver that contribute to the input of substrate precursors to the mammary gland after feeding a high-concentrate diet to lactating goats for a long period. EXPERIMENTAL DES...

Researchers have revealed many novel applications for plum and raisin products as functional natural bakery ingredients. Raisin and plum concentrate were incorporated into the bread formulation at different concentrations and their effects on the rheological, baking properties and shelf life of breads were evaluated. The results showed that the use of plum concentrate at 6% had the highest wate...
