The safe disposal of human excreta is of paramount importance for the health and welfare of populations living in low income countries as well as the prevention of pollution to the surrounding environment. On-site sanitation (OSS) systems are the most numerous means of treating excreta in low income countries, these facilities aim at treating human waste at source and can provide a hygienic and...

The objective of the study was to determine the effect of Quantum Blue phytase on P utilisation and bone parameter in laying hens fed barley, oat and soybean meal based diets. Over a period of 40 days 64 laying hens (from 29 weeks of age) were distributed to 4 treatments (8 cages, two birds each). Experimental diets with no inorganic P added were supplemented with 0, 150, 300 or 1200 FTU phytas...

This study examined enteric and excreta emissions from cattle pigs with a focus on effects of changed feeding practices. We assessed the impact revision Austrian Greenhouse Gas Air Pollutant Inventory (national method, NM), i.e., implementation Tier2-method IPCC-2019 guidelines, to more dynamic integration past present Cattle—in particular, dairy cows—had highest contribution CH4 nitrogen (Nex)...

A simple and efficient collection method using hypotonic burst to isolate virions from infected cultured cells is described. Distilled water treatment of avian metapneumovirus (AMPV)-infected cells with thorough mixing and repeated pipeting was considerably faster for virion collection in avian cells compared to the widely used freeze-thaw (F-T) method (30 min vs. 3-4 h). This method was also m...

The aim of this 3 × 3 factorial experiment on broilers was to investigate the effect of different dietary levels of potassium and chloride on chicken performance, carcass composition and dry matter content in excreta. 360 one-day-old Ross 308 chickens were allocated to 9 groups, in 5 replications of 8 birds (4 ♂ and 4 ♀). Chickens from 1 to 42 days of age were kept in cages with wire floors to ...

Pigeons have long been a common nuisance at numerous cultural sites in the Kathmandu Valley. Besides health, economic and aesthetic issues caused by pigeon excreta, this waste may also result damaging effects to materials used Nepalese architecture, including metals such as copper its alloys. This study assessed impact of excreta on metal-based monuments importance To test corrosive fresh were ...

Intrinsic phytase in swine feeds may increase phytate utilization and alter the solubility of the excreted P. The objective of this experiment was to quantify changes in fecal P composition from swine fed a variety of cereal grains containing a range of phytate concentrations and endogenous phytase activities. Twenty-five crossbred barrows (89.3 +/- 6.8 kg) were fed 1 of 5 dietary treatments th...
