the chemical composition, ruminal degradability parameters, ruminal and post ruminal digestibility of saffron residues were determined using in situ and in vitro (gas production) methods. the harvested residues at late vegetative phase were compared with the residues harvested at the early dormant phase. the results showed that ndf and adf concentration of harvested residues at early dormant ph...

the aim of this study was to investigate the fermentation characteristics and cellulolytic enzymes activities of dromedary camels rumen anaerobic fungi in fed with cultivated and pasture forages. hence, the inoculant of rumen anaerobic fungi was prepared by using specific medium and the gas production, digestibility and enzyme activity of rumen fungi were determined on the basis of a 2 × 2 fact...

the present experiment aimed at increasing orange peel and sugar beet pulp protein content through solid-state fermentation by trichoderma reesei and trichoderma viride. in vitro digestibility and changes in the chemical composition of the fermented products were determined after seven days of fungal cultivation using gas production tests. the cultivation of t. reesei and t. viride on orange pe...

In vitro techniques were evaluated to determine the nutritive value of a selection of tanniniferous tree and shrub legumes (Calliandra calothyrsus, Leucaena leucocephala L. diversifolia and L. pallida) compared with lucerne (Medicago sativa). Polyethylene glycol (PEG) was also added to some in vitro fermentations (10 mg PEG/50 mg plant substrate) to assess the effects of tannins on digestion of...

Digestibility of starch is an essential issue in food science studies due to its close relationship with human health. Most common starchy foods contain rapidly digestible starch, which can lead chronic diseases, including type II diabetes. Heat–moisture treated potato (HPS) followed by inclusion complexation guest molecules prepared improve starch's physicochemical properties, resulting reduce...

Twenty-one genetically lean, obese or contemporary slaughter weight castrated male pigs (6 mo old; seven of each genotype) were assigned to individual tether stalls and fed either a control diet (low fiber) or a diet containing 80% alfalfa meal (high fiber) at 1.50% of initial body weight for 71 d (1.75% for d 1 to 4). Apparent dry matter digestibility of the diets was estimated by determining ...

We have shown in previous reports that cooked sorghum protein is less digestible than other cooked cereal proteins. The pepsin-indigestible proteins in sorghum were found to be mainly prolamin proteins. Cooking sorghum in the presence of 2-mercaptoethanol increased protein digestibility (in vitro with pepsin or trypsin/chymotrypsin) to a level comparable with other cereals. At a concentration o...

sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, t1), 35% wheat straw (t2), 35% barley straw (t3) or 35% maize straw (t4). total-tract apparent digestibility for dry matter, organic matter...

this experiment was carried out for a determination of metabolizable energy and the effect of the grind multienzyme on in-vitro dry matter and protein digestibility in diets, and as well on performance of broiler chicks. a number of 800 day old unsexed arbor acres broilers were placed in 8 treatments and 4 replicates (25 chicks each). a completely randomized design (crd) of a factorial arrangem...
