Mode Of Inheritance

Evidence has been presented in the literature on the mode of inheritance of shank colour in various breeds of chickens, but little has hitherto been known about the same aspect in an Australian breed, the Black Australorp. Observations on the incidence of shank colour in different types of crosses between yellow-shanked White Leghorns and black-shanked Australorps are reported in this paper. According to the observations made by other workers on White Leghorn and other breeds, a hypothesis is advanced regarding the genes involved in determining shank colour in the White Leghorn and Australorp. A genetical analysis of the observations made by the authors on 847 single crosses, 71 backcrosses, and 31 zig-zag crosses is presented and shows close statistical agreement with the hypothesis. A genetical formula, including four autosomal and two sex-linked genes, is suggested which would explain the mode of inheritance of shank colour in White Leghorns and Australorps.

Potential Tool

Random amplified polymorphism DNA (RAPD) technique was applied to detect genetic similarity between seven local  chicken strains selected for eggs and meat production in Bangladesh. Conservation and improvement strategies     ought to be based on proper genetic characterization in association with phenotypic characterization. White Leghorn, White Rock, Rhode Island Red, and Barred Plymouth Rock fall under recognized strain and Hilly, Deshi and Necked Neck fall under native bird group. Based on four oligonucleotide primers, the genetic similarity between the eggproducing strains (White Leghorn; White Rock; Rhode Island Red and Barred Plymouth Rock) was between 81.3 to 89.3 %. While the genetic similarity of three native chicken strains selected for meat production (Hilly, Deshi and Necked Neck) was 69.0 to 78.7 % similar based on the RAPD Marker. So, RAPD markers appeared to be effective in detecting similarity between chicken strains and they provide a potential tool for studying the inter-strain genetic similarity.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.10989   J.

A short-term bioassay test using Single Comb White Leghorn (SCWL) laying hens was developed to study various fractions of fababeans, to determine the location of the egg-weight-depressing factor (EWDF), and to determine the effect of heat treatment on EWDF activity. A second objective of the research was to develop an extraction method to facilitate studies on identification and mode of action of the factor(s). The 14-day period proved useful in confirming that EWDF activity was concentrated in the cotyledon portion of fababean seeds and associated with the protein rather than the starch component. Ethanol-water extraction was effective in concentrating the factor.
