The control of metabolite production is difficult in mixed culture fermentation. This is particularly related to hydrogen inhibition. In this work, hydrogenotrophic methanogens were selectively enriched to reduce the hydrogen partial pressure and to realize efficient acetate production in extreme-thermophilic (70°C) mixed culture fermentation. The continuous stirred tank reactor (CSTR) was stab...

Unlike milk-based infant formulas, soy-based infant formulas containing supplemental fructooligosaccharides (FOS) have not been clinically evaluated. A randomized, double-blind, 28 day parallel feeding trial compared gastrointestinal (GI) tolerance and hydration in healthy term newborn infants fed either a commercialized soy formula (with history of safe use) containing sucrose as 20% of total ...

BACKGROUND Upon emergence from their pupal cells, bollworm, Helicoverpa zea (Boddie), adults actively seek and feed on plant exudates before they disperse and reproduce on suitable host plants. This nocturnal behavior of the bollworm may be exploited as a pest management strategy for suppression of the insect by using an attractant/stimulant mixed with an insecticide to induce feeding to cause ...

The administration of a carbohydrate-containing diet for 24 hours to rats previously fasted for 3 days led to a twofold increase in total intestinal sucrase and sucrase specific activity. The specific activity of maltase was similarly increased, but lactase activity was unaffected. The sucrose-containing diet led to a greater increase in sucrase than maltase activity, whereas the converse was t...

In this experiment, B. subtilis was added to pelletized straw-based total mixed ration, and the rumen microbial diversity of house-fed Duhan hybrid sheep compared. Ten 3-month-old weaned lambs were separated into two groups fattened for 80 days using a single-factor trial design. During fattening period, control experiment fed with same except that group supplemented subtilis. The results showe...

The effects of propylene glycol (PEG) on performance, ruminal fermentation, blood glucose and insulin, carcass traits, and abundance of IGF-1 mRNA in LM and leptin mRNA in adipose tissue were examined in 20 Korean native steers, with 10 each in control and PEG-fed groups, respectively. Propylene glycol mixed with concentrate diet was provided daily at a rate of 2.5 mL/kg BW(0.75). Experimental ...

Effects of a supplemental fermented agro by-products diet on growth performance, blood characteristics and carcass traits were investigated in fattening pigs. The fermented diet mainly contained 38.0% brewer’s grain, 25.0% rice bran and 21.0% byproduct of king oyster mushrooms. The mixed ingredients were fermented at 40°C for 7 days and fed to crossbred barrow pigs for 62 days. Ninety pigs were...

A field experiment was conducted on an Orobanche naturally infested soil at Sakha Agricultural Research Station - Kafr El Sheikh, in 2017/2018 and 2018/2019 seasons aiming combating crenata faba bean through using waterextracts of fenugreek, coriander sorghum crops, each a concentration 10% weight/volume rate 20 litres/fed mixed with glyphosate (48%) reduced (40cm3/fed) compared to the recommen...

introduction poultry meat enriched with long-chain polyunsaturated fatty acids n-3 (pufa lc n-3) can make a nutritionally meaningful contribution to western diets in which consumption of pufa lc n-3 is low. enrichment of poultry meat with this fatty acid is usually achieved by inclusion of fish oil in broiler diet (23, 24). however, meat enriched in this way is susceptible to quality deteriorat...
