Organic livestock production has increased dramatically in recent years in Europe and other parts of the world. The aim of producing livestock under more natural conditions has led to a reversion to primarily outdoor production systems and less intensive housing when indoor, more forage-based diets, and a reduced reliance on external inputs like antiparasiticides. These major changes in livesto...
This review paper traces the origin of formal urban housing problems in Kenya. It indicates that formal urban housing problems have their origins in the colonial period where discriminatory policies led to the skewed housing provision. The problems were further compounded during the post-colonial period, where the independence government operated for a long time without an explicit policy on ho...

Mortgage markets are coming of age in a number of Eastern Europe and CIS countries. As they do, governments are looking to mortgage-loan associated subsidy schemes to respond to the popular demand for improved housing. This paper presents a detailed examination of the impact of two types of subsidy schemes—mortgage interest rate write-downs, both universal and income-targeted, and income-target...
Air Quality in Alternative Housing Systems May Have an Impact on Laying Hen Welfare. Part II—Ammonia
The EU ban on conventional barren cages for laying hens from 2012 has improved many aspects of laying hen welfare. The new housing systems allow for the expression of highly-motivated behaviors. However, the systems available for intensive large-scale egg production (e.g., aviaries, floor housing systems, furnished cages) may cause other welfare challenges. We have reviewed the literature regar...
Two epidemic waves of an avian influenza A (H7N9) virus have so far affected China. Most human cases have been attributable to poultry exposure at live-poultry markets, where most positive isolates were sampled. The potential geographic extent of potential re-emerging epidemics is unknown, as are the factors associated with it. Using newly assembled data sets of the locations of 8,943 live-poul...
In the United States, empirical information on the sustainability of commercial-scale egg production is lacking. The passage of state regulations specific to hen housing created urgency to better understand the effects of different housing systems on the sustainability of the egg supply, and stimulated the formation of a coalition, the Coalition for a Sustainable Egg Supply (CSES), to conduct r...
Stress during pregnancy is associated with metabolic dysfunction in the adult offspring in human and other animals. However, little is known about the metabolic effects of pregnancy stress on the mothers and fetuses during pregnancy itself. This study aimed to determine the consequences of the common experimental procedures of injection and single housing in pregnant rats on fetal and maternal ...
This paper explores contractual features of housing Þnance and uses data from international housing markets to provide evidence supporting the Þnancial accelerator (Bernanke et al. 1996, 1999). Among households whose housing demand is constrained by the availability of collateral, those who can borrow against a larger fraction of the housing value (achieve higher loan-to-value, or LTV ratio) ...
Poultry by-products and rainbow trout (Onchorhynchus mykiss) viscera are abundant and underutilized resources that can be used as a unique protein source to make protein hydrolysates. In this study protein hydrolysate were made from these two different sources with Alcalase 2.4L. The functional properties of Fish viscera protein hydrolysate (FPH) compared to poultry by-products protein hydrolys...
