Ostrich chick mortality was studied in 2522 chicks that were hatched artificially during the 1999/2000 breeding season. High levels of mortality were observed, with 1978 (78.4 %) of these chicks dying before 90 days after hatching. A total of 46.7 % (1,177) of these chicks died before 28 days of age, and a further 30.7% (801) died between 28 and 90 days post-hatching. Chick mortality to 28 days...
total of 270 quail fertile eggs were set in hatchery. experimental groups including: negative control (neither received probiotic treatment nor challenged by salmonella), positive control (challenged by salmonella but not probiotic treatment) and 7 in hatchery administration methods: in ovo injection, spray, oral gavage, cloacal drinking (cloacal inoculation), cloacal drinking – in ovo injectio...
Aims: This study seeks to evaluate the growth performance and physiological response of broiler chickens brooded with blue, black, white green side-curtains. It is essential ensure that thermal conditions within poultry building are controlled most especially in tropical climate where temperature observed exceed thermoneutral zones chickens. During brooding stage chicks, suitable relative humid...
Th e aim of this study was to observe the microstructure and ultrastructure of the testis, demonstrate testicular cell development and apoptosis, and elucidate regularity of development and apoptosis in ostrich chick testes. By employing light microscopy 3 obvious development characteristics were detected with ostrich age increasing: fi rst, many primordial germ cells and a few spermatogonia we...
