Psychrophilic anaerobic digestion of guinea pig manure in low-cost tubular digesters at high altitude
(ELSEVIEREstados Unidos, 2011-03-29)
Guinea pig is one of the most common livestock in rural communities of the Andes. The aim of this research was to study the anaerobic digestion of guinea pig manure in low-cost unheated tubular digesters at high altitude. ...
Comparação do Sistema de Monitoramento Computadorizado de Digestão in Vitro com os Métodos in Vivo e in Situ. 2. Uso do Resíduo da Matéria Seca de Forragens
(2000-03-01)
The objective of this work was to compare the computerized monitoring of the in vitro gas production system with the in vivo and in situ methods. On the comparisons, corn silage with high/low dry matter contents, with/without ...
Modulation of digestive enzyme activities in the avian digestive tract in relation to diet composition and quality
(Springer Heidelberg, 2017-02)
In nature, birds are faced with variable food sources that may differ in composition (protein vs. carbohydrates) and quality (highly digestible material vs. indigestible fiber). Studies in passerine birds and some commercial ...
Morphology and Cyclic Activity of the Digestive Gland of Zidona dufresnei (Caenogastropoda: Volutidae)
(Institute of Malacology, 2015-04)
Zidona dufresnei is a carnivorous snail that plays an important role in the trophic web as a top predator. It is a threatened species due to high levels of fisheries exploitation. In this study, we describe the morphology ...
Effect of different diets on digestive enzyme activities, in vitro digestibility, and midgut gland structure in juvenile crayfish, Cherax quadricarinatus
(Wiley Blackwell Publishing, Inc, 2016-10-17)
This study investigated the effects of food quality on digestive enzyme activities, in vitro protein digestibility and histological traits of the midgut gland in juvenile crayfish Cherax quadricarinatus. Animals of a wide ...
Microstructure, mechanical properties, and starch digestibility of a cooked dough made with potato starch and wheat gluten
(ELSEVIER, 2011)
Processed starch-protein foods may exhibit a variety of microstructures, hence different mechanical properties and starch digestibility but the relation between these parameters is yet to be resolved. This paper reports ...
Assessment of rheological and microstructural changes of soluble fiber from chia seeds during an in vitro micro-digestion
(Elsevier, 2018-09)
The ability of some dietary fiber to increase the viscosity of digestive content may be associated with important positive implications in human health. An in vitro micro-digestion device was implemented to simulate and ...
Fabrication, characterization and lipase digestibility of food-grade nanoemulsions
(ELSEVIER SCI LTD, 2012)
The behavior of nanoemulsion-based delivery systems within the gastrointestinal tract determines their functional performance. In this study, the influence of particle radius (30-85 nm) on the in vitro digestion of ...
Microbiome network analysis of co-occurrence patterns in anaerobic co-digestion of sewage sludge and food waste
(IWA Publishing, 2019-06-15)
Addition of food waste (FW) as a co-substrate in anaerobic digesters of wastewater treatment plants is a desirable strategy towards achievement of the potential of wastewater treatment plants to become energy-neutral, ...
Nutrient digestibility, but not mineral absorption, is age-dependent in cats
(Wiley-Blackwell Publishing, Inc, 2010-12-01)
Availability of nutrients is influenced by extremes of age, and a better characterization of this influence is necessary for appropriate development of foods and nutritional management throughout life stages of cats. This ...
