By 2010 Africa's urban population will have grown to over 420 million with on-site sanitation the predominant excreta disposal option. The use of on-site sanitation has important public health benefits but can result in large faecally derived loadings of nitrogen and chloride to groundwater resources. Nitrate is of particular concern, with elevated concentrations linked to potentially serious h...

This study determined the metabolizable energy of DDGS for broiler quails (Experiment I) and evaluated effect different dietary levels on performance, carcass, organ weight, meat quality, economic viability II). In Experiment I, 72 were randomly distributed into two treatments (reference or test diets). The experimental period consisted 5 days adaptation, followed by total excreta collection. E...

ABSTRACT Cassava by-products are abundant and largely unused in familiy agro-industries the Amazon region, where slow-growing broilers commonly raised. Thus incorporation of cassava broiler feed may provide starch enrichment for better zootechnical performance. We evaluated use residues instead corn diet broilers. determined chemical composition scrapings (CS) residue (CSR), tested digestibilit...

Reducing N excretion from individual cows is one way among others to better cope with the problem of the negative contribution of the dairy herd to the “Nitrogen cycle” on the farm. The objectives of this paper are first to quantify the effects of the main forage systems and protein feeding level on the amount of N excreted in relationship to their simultaneous effects on animal performances an...

Several studies have reported data on comparisons between two methods: the total collection of feces and the internal markers method. The aim of this study was to assess the apparent digestibility of two concentrates and to compare the apparent digestion coefficients using the total collection of feces and acid-insoluble ash (AIA) as the internal marker method. In 2009, six adult geldings aged ...

An experiment was conducted to evaluate the effect of dietary content and combinations of Zn, Fe, and Cu on deposition of these elements in egg components, liver, and excreta. Excreta were applied as a manure to a lawn, and 3 mo later soil and herbage samples were taken and analyzed. The experiment comprised 144 hens in 8 groups. The basal diet contained Zn, Fe, and Cu at 63.4, 92.8, and 9.0 mg...

Microbiota plays a role in the release and absorption of nutrients from feed components, thereby affecting digesta composition and moisture content of the excreta. The objective of the current study was to determine the effects of 5 different diets varying in ingredients (medium-chain fatty acids, nonstarch polysaccharides, and starch) on the microbiota composition of ileal digesta of broiler c...

BACKGROUND Diarrhoeal diseases are a leading cause of mortality and morbidity, especially among young children in low-income countries, and are associated with exposure to human excreta. OBJECTIVES To assess the effectiveness of interventions to improve the disposal of human excreta for preventing diarrhoeal diseases. SEARCH STRATEGY We searched the Cochrane Infectious Disease Group Special...
