Recent increases in imports of catfish, shrimp, and crawfish have caused concern as to their impact on domestic prices. This study seeks to identify the linkages between imports of these goods and producer prices. Increases in imports of catfish and shrimp are shown to decrease related domestic prices. However, recent trends show a simultaneous increase in both imports and domestic prices of cr...

T he domestic fowl has a long and unique history, serving multiple purposes in society and science. A cursory review of the Nobel Prize awards in physiology or medicine since 1901 points to the significance of birds, and the chicken in particular, as the premier nonmammalian vertebrate animal model (see www.fbresearch.org/education/ nobels.htm and http://nobelprize.org/ nobel prizes/medicine/la...

TH• extensive investigations that have been carried on in the field of avian embryology have largely concerned the chicken as a representative subject. There are, however, two different general types of development among birds, namely: the nidifugous type, which results in the precocial condition at hatching, and the nidicolous type, which gives rise to the altricial condition. Various degrees ...

BACKGROUND Understanding the factors that affect the host-feeding preferences of triatomine bugs is crucial for estimating transmission risks and predicting the effects of control tactics targeting domestic animals. We tested whether Triatoma infestans bugs prefer to feed on dogs vs. chickens and on dogs vs. cats and whether vector density modified host choices and other vital rates under natur...

In addition to causing 12 human deaths and 17 cases of human infection, the 2004 outbreak of H5N1 influenza virus in Thailand resulted in the death or slaughter of 60 million domestic fowl and the disruption of poultry production and trade. After domestic ducks were recognized as silent carriers of H5N1 influenza virus, government teams went into every village to cull flocks in which virus was ...

The conversion of a live chicken into safe and wholesome meat products suitable for human consumption takes place in a series of processing steps. Few of the processes require force to carry it out successively among which are slaughtering and de-feathering. The latter is the focus in this paper, plucking force of chicken produced from two breeds of chicken. Each sample of the chicken carcass w...

OPULATIONS of fully pedigreed chickens often contain individuals which ’deviate considerably in one or more respects from the average for the flock. When pedigrees reveal close genetic relationship among those similarly affected, further studies are warranted. Such was the case for the trait now recognized as hypothyroidism. Affected 5 %-month old White Leghorn pullets, which were somewhat smal...

In this paper, we report on the ongoing work in our laboratories on the effect of lateralization produced by light exposure in the egg on social cognition in the domestic chick (Gallus gallus). The domestic chick possesses a lateralized visual system. This has effects on the chick's perception towards and interaction with its environment. This includes its ability to live successfully within a ...
