Indigenous chickens (IC) are mainly raised by resource poor rural households in developing countries [1]. Although they are of low genetic potential compared to the commercial breeds, IC play a vital role in livelihoods of farmers and contribute significantly to food security and income [1]. IC dominates in most smallholder farms in Malawi and they are deemed less productive but appear to be ad...

Laughter in speech has been studied mostly relying upon the spectral representation like formants and harmonics derived from the short-time spectrum. Significant changes appear to take place in the characteristics of glottal source of excitation during the production of laughter, but these changes have not been explored much. In this study, we examine the changes in the glottal vibration charac...

The aim of this research was to evaluate the changes in the Gelato ice cream properties at different levels of sweet whey protein concentrate (WPC) substitutions of egg yolk. Samples were made with two levels of egg yolk (4.5 and 9%). For each level one control sample with no WPC addition and four levels of WPC substitutions (20, 50, 80 and 100%) were made. Three replications of each treatment ...

Brood parasitism frequently leads to a total loss of host fitness, which selects for the evolution of defensive traits in host species. Experimental studies have demonstrated that recognition and rejection of the parasite egg is the most common and efficient defence used by host species. Egg-recognition experiments have advanced our knowledge of the evolutionary and coevolutionary implications ...
