. an experiment was conducted by incorporating 35 newborn balouchi lambs to study the effects of different type and levels of forage in starter diets on rumen development characteristics and performance. the 5 experimental treatments were included; starter diet without forage (control) and starter diet containing two levels (7.5 and 15%) of alfalfa hay and wheat straw. inclusion of forages incr...

Each year, millions of tons of agricultural residues such as wheat straw are produced worldwide. In this paper, we describe ongoing efforts to solve technological, infrastructural, and economic challenges to using this straw for bioenergy and bioproducts. Among these challenges, silica in straw forms a low-melting point eutectic with potassium, causing excessive slagging deposits in boilers. Th...

The objectives of these experiments were to study the positive associative effects of supplementing barley straw-based diets with different levels of alfalfa hay on nutrient intake, rumen environment, and nutrient digestibility and to evaluate the minimal amount of alfalfa hay needed to produce such an effect in ewes. In experiment one, 15 Awassi ewes (®ve ruminally ®stulated; body weight ˆ 54 ...

Crude fibers (CF) take a special place in the growing rabbit`s nutrition. In depend on their origin and composition, CF have digestibility 1725% in the roughages and up to 40-50% in the green and concentrate feeds. They are very important in the regulation of the processes of both digestibility and bacterial synthesis. The optimal CF quantity for growing rabbits is 12-15%. Alfalfa hay is prefer...

the present experiment was carried out to investigate the nutritive value of banana tree leaves and stems silage by use of in vitro gas production and as well in situ nylon bag techniques. experimental treatments were comprised of: 1- stems and leaves of banana trees (control), 2- stems and leaves of banana trees’ silage without addition of any additive, 3- stems and leaves of banana trees’ sil...

An experiment was carried out to compare the effect of feeding posidonia australis as a non-conventional feedstuff with cereal straw for sheep maintenance; and to compare seagrass/chicken litter with lucerne hay and pasture for sheep production on a scale such as would be applicable to lot-feeding of sheep in the area of suthern Australia in case of short term feed scarcity. To approach this ta...

An integrated process has been developed for a wheat straw biorefinery. In this process, wheat straw was pretreated by soaking in aqueous ammonia (SAA), which extensively removed lignin but preserved high percentages of the carbohydrate fractions for subsequent bioconversion. The pretreatment conditions included 15 wt% NH4OH, 1:10 solid:liquid ratio, 65 C and 15 hours. Under these conditions, 4...

This research investigated the effect of hot water pre-extraction on the bleaching process and properties of wheat straw soda-AQ pulp. Preextraction experiments were carried out on wheat straw to obtain a weight loss of about 15 percent. Based on preliminary experiments, soda-AQ pulping of non-extracted straw chips was performed at 160 oC for 60 min, whereas the pre-extracted chips were pulped ...
