Erysipelothrix rhusiopathiae in Laying Hens
The bacterium Erysipelothrix rhusiopathiae can infect a wide range of mammals (including humans) and birds. Disease outbreaks (erysipelas) have been considered unusual in chickens internationally, but outbreaks with high mortality and egg production losses have been diagnosed in Swedish laying hen flocks every year since 1998. Different aspects of E. rhusiopathiae infection in chickens were exa...
متن کاملComparative gonadotrophic potency of anterior pituitaries from cocks, laying hens and non-laying hens in molt.
A bulk of studies on the assay of gonadotrophic hormone content of the anterior pituitary from the animals in various reproductive conditions has been done. Riley and Fraps(1942b) assayed pituitary glands from chickens in various reproductive stages, judging the gonadotrophic potency by the increment of uterine weights of immature mice, and concluded that glands from non-laying hens produced a ...
متن کاملDetermination of space use by laying hens using kinematic analysis.
Two states in the United States now have legislation requiring that laying hens be provided with sufficient space to perform particular behaviors. To provide a framework for translating these performance standards into a space requirement, kinematic analysis was used to measure the amount of space needed for White Leghorn hens to stand, turn around 180°, lie down, and wing flap. Hyline W-36 hen...
متن کاملStress Detection and Classification of Laying Hens by Sound Analysis
Stress adversely affects the wellbeing of commercial chickens, and comes with an economic cost to the industry that cannot be ignored. In this paper, we first develop an inexpensive and non-invasive, automatic online-monitoring prototype that uses sound data to notify producers of a stressful situation in a commercial poultry facility. The proposed system is structured hierarchically with three...
متن کاملType of Fatty Acids, Lipoprotein Secretion from Liver and Fatty Liver Syndrome in Laying Hens
Unlike other vertebrates, liver is the main site of lipid biosynthesis and is particularly very active in egg laying adult females. Yolk lipids and proteins are secreted as lipoproteins under the influence of estrogen in the liver. When hepatic lipogenesis exceeds the capacity of fat transport as lipoproteins, triacylglycerols commence to accumulate in the liver, leading to fatty liver syndrome...
