The low intake and digestibility of low-quality roughages such as mature forages or crop residues often results in a digestible energy intake insufficient for a desired level of production. One alternative to increase digestible energy intake is to provide supplementary concentrates of high digestibility. ‘ Associative effects on forage fibre digestion may occur when roughage and concentrate ar...

Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study, the effects of concentrate of smoked and sun dried raisin were investigated at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread. Results showed that addition of smoked and sun dried raisin improved quality a...

BACKGROUND An experiment was conducted in Vietnam to test the hypothesis that total dry matter (DM) intake and liveweight (LW) gain would increase in a curvilinear manner with increasing amounts of concentrate offered. METHOD There were five treatments: a basal diet of Guinea grass fed at 1 % of LW and rice straw fed ad libitum (T0), or this diet supplemented with concentrate at 0.6 (T1), 1.2...

The impact of installing process control systems can be expected in terms of performance improvements through reduced operating costs.  Since these installations impose considerable capital expenditure, the profitability of the new systems should be economically justified. Controlled variable trend was reconstructed by a combination of simple waves, which provided a means to simulate the ef...

tabas mines in iran have coal sources which are suitable for use in metallurgy industries as coking coal. but the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. in this work, attempts have been made to reduce sulfur from high sulfur coal of...

in this research work, the zinc extraction was investigated, using bioleaching process from a low grade zinc concentrate which was produced from the accumulated flotation tailings. zinc content was initially upgraded to 11.97% by flotation process. bioleaching experiments were designed and carried out by a mixed culture of acidithiobacillus ferrooxidans, acidithiobacillus thiooxidans, leptospir...

utilizing natural clay in the traditional production of the grape concentrates in the villages cause the input of large amounts of some metals (solutes) in the product which will be harmful for the consumers. to eliminate the natural clay from this procedure in non-industrial scale, bentonite was selected as an aid-clarifier and examined in treatments under these conditions: two levels of bento...

N 2001, outlays by foreign direct investors to acquire or establish U.S. businesses decreased substantially, reflecting the slowdown in the U.S. economy and in the world economy. Outlays decreased 60 percent to $132.9 billion in 2001 from an exceptionally high level of $335.6 billion in 2000.1 The decrease, the first since 1997, was part of a sharp drop in overall merger and acquisition activit...

We study the link between family violence and the emotional cues associated with wins and losses by professional football teams. We hypothesize that the risk of violence is affected by the “gain-loss” utility of game outcomes around a rationally expected reference point. Our empirical analysis uses police reports of violent incidents on Sundays during the professional football season. Controlli...

A total of 240 Holstein bulls (121 ± 2.0 kg initial BW; 99 ± 1.0 d of age), from 2 consecutive fattening cycles, were randomly allocated in 1 of 6 pens and assigned to 1 of the 3 treatments consisting of different concentrate feeder designs: a control feeder with 4 feeding spaces (CF), a feeder with less concentrate capacity (CFL), and a single-space feeder with lateral protections (SF). Each p...
