In this paper, we use fuzzy rule-based classification systems for classify cells of the Eimeria of Domestic Fowl based on Morphological Data. Thirteen features were extracted of the images of the cells, these features are genetically processed for learning fuzzy rules and a method reward and punishment for tuning the weights of the fuzzy rules. The experimental results show that our classifier ...

Poultry are commonly infected with a wide variety of salmonella serovars and infection is generally subclinical (Wray et al., 1996). Poultry farming is often hampered by reduction in productivity due to infections with large number of bacteria, salmonellosis being the most important causing great economic losses due to mortality and reduction in egg production (Khan et al., 1998). Under the new...

Biochemical and serological studies were conducted on 73 Pasteurella multocida isolants associated with fowl cholera, 13 from waterfowl, 19 from free-flying birds other than waterfowl, 18 from chickens, 5 from turkeys, and 18 from White Pekin ducks. Three serotypes (1, 3, and 7) were associated with waterfowl, four (1, 3, 6, and 8) with free-flying birds, three (1, 3, and 4) with chickens, one ...

IN a recent communication, Dr F. A. E. Crew described one case of complete sex reversal in the domestic fowl and seven others showing different stages in this process. The whole formed a consistent series which demonstrated the fact that an individual which had previously functioned as an active female producing eggs can on occasion undergo a complete sex transformation and come to function as ...

Bang and Ellerman, and later Peyton Rous, reported the first identification of transmissible cancer-causing agents, which later turned out to be avian retroviruses. Today avian retroviruses are important models for study of retrovirus replication and pathogenesis, and also important pathogens of domestic fowl. Here we describe the use of RNA interference (RNAi) in live chick embryos to block re...

Data are presented showing that the course of decline of egg production with age in the domestic fowl from the time laying begins up to and including 8 years follows an exponential law, that is, each year's egg production is a constant percentage of the preceding year's production (88 per cent in the group of fowl studied). Since the exponential law is the same as the law of monomolecular chang...

1. The distribution of sialic acid in the eggs of original Silky fowl was investigated. The sialic acid contents of the yolk, albumen and the chalaza of a single egg were 205.2, 11.96 and 0.83 mg, respectively. 2. The sialic acid content of the yolk of Silky eggs was 11.5-fold higher than that of a conventional domestic fowl yolk. 3. Sialic acid isolated from Silky yolk was entirely N-acetylneu...

Little is known about factors which enable Salmonella serotypes to circulate within populations of livestock and domestic fowl. We have identified a DNA region which is present in Salmonella serotypes commonly isolated from livestock and domestic fowl (S. enterica subspecies I) but absent from reptile-associated Salmonella serotypes (S. bongori and S. enterica subspecies II to VII). This DNA re...

This study was aimed at investigating the use of seminal plasma protein concentration to predict fertility and hatchability in the domestic fowl. Forty cocks with acceptable sperm motility and morphology were used and the seminal plasma protein concentration determined by the Biuret method. The result revealed a negative significant correlation between the seminal plasma protein concentration w...
