This case report describes visceral gout in laying hens caused from deprivation of water supply as a consequence of limiting access for drinking water. In two different layer farms, nineteen week old pullets had a sudden and increased mortality rate. Gross pathology revealed typical uricosis lesions including: deposition of uric acid and its salts in kidney, pericardium, liver, muscle atrophy a...

Based on evidence from rodent models, it was hypothesized that furan fatty acids found in corn would inhibit reproduction in the laying hen. An isomeric mixture of furan fatty acids [9, (12)-oxy-10,13-dihydroxystearic acid and 10, (13)-oxy-9,12-dihydroxystearic acid] was administered for a period of 3 wk via the diet (1 and 3 ppm) at levels greater than those in corn to 20-wk-old pullets. There...

Purpose This paper aims to analyze the evolution and interaction over time of functions a technological innovation system (TIS) based on concept an motor. Design/methodology/approach It is case study associated with technology for producing cage-free pullets laying eggs in Pelotas/Rio Grande do Sul (RS). Findings The motors proposed by TIS approach evolve sequentially are cumulative causality m...
