Prevalence and pathology of oviduct impaction in commercial white leghorn layer chicken in Namakkal region of India
The female reproductive tract is commonly referred to as oviduct in birds. The oviduct is a highly convoluted muscular duct, concerned with the transport of the ovum away from the ovary, with fertilization of the ovum and by the deposition of albumen, membranes and shell on to the ovum to form the finished egg [1]. Reproductive diseases in poultry causes high morbidity (35%), mortality (15%) an...
متن کاملSeroprev Alence and Pathology of Egg Drop Syndrome (eds-76) in Commercial Chicken Layers
From September 1994 to April 1996, the aetiology of sudden decrease in egg production in commercial layer flocks was investigated. Clinical manifestations were recorded and the egg-shell quality was evaluated in 80 affected flocks. Serological screening was conducted twice at fortnightly intervals to record antibody titres against egg drop syndrome (EDS). Out of 80 flocks with lowered productio...
متن کاملPhosphorylation in vivo of chicken oviduct progesterone receptor.
Progesterone receptor from an oviduct tissue mince incubated with (32P)orthophosphate was purified using affinity chromatography, gel filtration, and DEAE-Sephadex chromatography. Two receptor peaks were eluted from the DEAE column. Peak I contained one major protein band with a molecular weight of 90,000 and a 32P band at 90,000. Peak II also had a major 90,000-dalton protein band and a 32P ba...
متن کاملHereditary persistent right oviduct in the chicken PNP/DO line.
Hereditary, persistent, right oviduct manifested in an inbred line (PNP/DO line) from the Fayoumi breed of chickens was investigated for form of expression and mode of inheritance. Females in the PNP/DO line have varying lengths of elongated right oviducts, besides the normal left ovary, and oviducts that generally possess, irrespective of their total length, regions similar to those normally o...
متن کاملExtent and consistency across generations of linkage disequilibrium in commercial layer chicken breeding populations.
Recent studies report a surprisingly high degree of marker-to-marker linkage disequilibrium (LD) in ruminant livestock populations. This has important implications for QTL mapping and marker-assisted selection. This study evaluated LD between microsatellite markers in a number of breeding populations of layer chickens using the standardized chi-square (chi(2')) measure. The results show appreci...
