Effect of cool brooding climate on chick performance

Brooding of young chicks [0-4 wk] in cool environment [24.4 C] exposed them to acute stress especially for the 1st few days which was reflected on the health state of the bird all over the growing period. Economic losses were, due to the decrease in live body weight [60.3 gm] and the difference in food conversion [1.96] in comparison with [1.48] in control one [1.48]

Studying the effect of stocking density on some aspects of pigeons performance

In the present study, the effect of stocking density on pegion performance was studied, the performance included, consecutive egg laying period, productivity percent. In addition the sequalae of high stocking was studied [Mortality% and the incidence of some diseases]. High stocking density influenced the period of egg incubation and consecutive laying periods. It also decreased the production and increased the susceptibility to diseases

Effect of some environmental and chemical agents on the development of the most pathogenic eimeria species oocysts of goats

Faecal samples collected from the rectum of 4 Zariby kids [2 months of age] suffering from severe diarrhea, were examined for Eimeria, globidium and cryptosporidia oocysts. The effect of temperature and dessication in sunlight and shade on the development of E. arloingi, E. ninakohlyakimovae, E. faurei and E. parva was studied. Some chemical agents were also used to study their effect on the sporulation of the oocysts

possible role of domestica in transmitting fungal agents

Twenty two fly [M.domestica] samples were collected from cattle byres, poultry houses and human houses in different localities to investigate the possible role of flies in transmitting pathogenic fungi. A. terreus A. flavus and mucor spp. were isolated from the flies. In addition yeasts [C.albicans and others] were recovered. Great number of fungal isolates were recovered from cattle byre's flies while few isolates were recovered from flies of poultry houses and human houses; respectively

Studies on the role of newly-emerged Musca domestica in transmission of human and animal pathogens and means of their control

The role of newly emerged musca domestica in transmission of human and animal pathogens and the means of control were studied. The results indicated that the newly hatched flies of animal and poultry manure considered as reservoirs of pathogens; E. coli, pseudomonas aurigenosa, staphylococci, salmonellae, streptococci and corynaebacterium renale, as well as different parasitic forms of animal and poultry. Six chemical compounds were tested in the field as Slaked lime, copper sulphate, Borax, Formalin, Diazinon, and Neguvan against the pupal stage of Musca. The efficiency of these chemical compounds indicated that, slaked lime, copper sulphate, Borax and Neguvon were satisfactorly effective

Evaluation of the antifungal activity of enilconazole against pathogenic fungi

Imaverol [Enilconazole] was proved to kill spores of aspergillus fumigatus after 10 minutes to 1 micro g/m1 [AOAC method]. A concentration of 1 mg/m1 killed dermatophytes after 5 minutes and 3 mg/m1 killed Candida albicans after 10 minutes

clinical observation of the effect of temperature, relative humidity and slaked lime on the viability of the faecal ocystic zygotes of eimeria labeanea of pigeons

The effect of temperature, humidity and slaked lime on the most common coccidiodin organism [Eimeria labeanea] in Baladi pigeons was studied. Indeed the oocystic stage appeared to be variably affected by temperature and humidity in their microhabitats. Slaked lime proved to be efficient in the destruction of the oocysts

effect of hay making on the survival of some parasitic stages

The effect of hay processing on the infective stage of Strongylus vulgaris and Toxocara vitulorum eggs was studied. Indeed the infective stage of S. vulgaris appeared to be resistant and approximately 35% of the larvae survived in hay but Toxocara vitulorum eggs were rapidly destroyed
