Embryonic Mortality is the major cause of reproductive and economic loss in cattle Buffaloes. more common during early than late embryonic period, i.e., from day 8th to 16th at hatching blastocysts initiation elongation commencement implantation without affecting cycle lengths. Early mortality a source with rate up 40%. also reported due mineral deficiency heat stress buffaloes. Physical modifi...

Two experiments, which included 3 incubators, were carried out to investigate the effects of egg weight and position relative to incubator (setter) fan on embryonic mortality, second quality chicks, and fertile hatchability of broiler eggs. Three egg weight groups termed small (approximately 62.4 g), average (approximately 65.4 g), and large (approximately 68.9 g) were set in either the incubat...

In this study, the effects of pre-storage coating different ratios gum arabic on hatching traits and chick growth performance were investigated. Treatment groups; eggs treated with 5% stored for 7 days (7-5G), 14 (14-5G), 10% (7-10G) applied (14-10G). After application, at 13 °C 75% humidity or days. a total 800 used, 200 in each four groups. Regardless have less egg weight loss than (P<...

High ambient temperature is a major factor for diminishing reproductive performance of broiler parent stocks. Homozygous naked neck (NaNa) broilers, which possess a higher adaptation to heat due to a reduction of feather coverage, exhibited higher growth rates and meat yield. This study was conducted to investigate the influence of genotype x temperature interactions on the reproduction traits ...
