OBJECTIVE Rice Bran Oil (RBO) is extracted from the outer layer of rice. Little information is available regarding its safety. The present study was conducted to assess its safety in chicken embryo model. MATERIALS AND METHODS RBO was injected on day 4 of incubation of chickens. The tissues and serum samples were collected. Oxidative stress parameters in the liver, kidney and brain and bioche...

An experiment was carried out to study the hematological and biochemical changes of stunting syndrome in broiler chicken from day old ( group I) and 3 weeks (group III) of age to 8 weeks of age in two phases along with group II and group IV as control. Birds were slaughtered at 3, 5 ,7 and 8 weeks of age and the blood samples were collected and analyzed. The mean PCV, Hb, TEC values were reduce...

BACKGROUND The central premise for the commercialization of diets with hydrolyzed ingredients is that the small-sized digested peptides would be unable to crosslink allergen-specific IgE at the surface of tissue mast cells and induce their degranulation. Evidence for the validity of this concept to diagnose food allergies in dogs and cats is limited, however. Our objectives were to study the re...

A common challenge in avian cell biology is the generation of differentiated cell-lines, especially in the keratinocyte lineage. Only a few avian cell-lines are available and very few of them show an interesting differentiation profile. During the last decade, mammalian embryonic stem cell-lines were shown to differentiate into almost all lineages, including keratinocytes. Although chicken embr...

STRATEGIES FOR THE IMPROVEMENT OF RURAL CHICKEN PRODUCTION IN GHANA. Rural poultry production systems in Ghana and in Africa as a whole are based on the scavenging indigenous domestic fowl (Gallus domesticus), the predominant species in the poultry sector [1]. In most African countries scavenging chicken have no regular health control programmes, may or may not have shelter and usually have to ...

Neurological signs like ataxia and hind limb paresis have often been reported in cheetahs (Acinonyx jubatus), lions (Panthera leo) and snow leopards (Panthera unica). As a cause, copper and Vitamin A deficiencies have been discussed. Many cases were seen in cheetahs and lions in the United Arab Emirates (UAE) within the last years. The aim of this study was to find correlations between nutritio...

this study was conducted at beresa watershed district of guraghe administrative zone, the southern regional state of ethiopia to evaluate the on-farm reproductive and egg production performances of local kei and its f1 crosses with fayoumi and rhode island red (rir) chicken breeds under farmers’ management. the local kei paternal line was mated with maternal lines of fayoumi and rir chickens to...

In a culture medium of pH 7.4 and a folic acid concentration of 100 mug/liter that contains 5% heat-inactivated chicken plasma rather than serum, the rate of proliferation of normal chicken fibroblasts is determined by the concentration of calcium. Proliferation, rapid when the calcium concentration is physiological, decreases when the calcium concentration is reduced. At a very low calcium con...

An accumulated turbidity and the presence of many bacilli in the plasma surrounding lepromatous tissue culture explants has been emphasized by Timofejewsky (1) and by Suwo and Kin (2) as indicating the multiplication of free bacilli in the plasma itself. Since this inference seems unwarranted by the observations made during the preceding studies with tissue cultures, it is desired to explain wh...

The function of the enzyme butyrylcholinesterase (BChE) both in serum and in brain is unclear. In serum, BChE has been found complexed with several biomedically relevant proteins, with which it could function in concert. Here, the existence of a similar complex formed between BChE and sero-transferrin from adult chicken serum was elucidated. In order to identify both proteins unequivocally, we ...
