Abstract

The frequency of insemination in hens affects the costs associated with artificial insemination in poultry. A reduced frequency implies a larger insemination interval and therefore a reduction in costs. The objective of the study was therefore to assess the effect of insemination intervals on...

Abstract

DNA uptake in the post-acrosomal region of the spermatozoa takes place exclusively in immotile spermatozoa that are naturally unable to fertilize eggs. The present study aimed to assess whether passive transmission of non-viral vectors to the surrounding areas of chicken embryos could be an...

Abstract

Probable involvement of avidin and avidin-related protein-2 (AVR2) in sperm viability in the sperm storage tubules of turkeys has been suggested. The high affinity of biotin to avidin and its analogs is also well documented. The present study aimed to determine the effect of oral biotin on...

Abstract

Large-type White turkey hens from a flock with a record of low "fertility" (live embryos at 7 to 10 days' incubation) were distributed at random into four groups each of 50 and were given treatments involving antibiotic and inseminations on a weekly or fortnightly schedule. During the first 5 weeks ...

Abstract

At present 45% of all unfertilized eggs undergo some development during incubation, 12-13% contain embryos, 34% of these embryos live 21 days or more, and 7% hatch. Most are weak or malformed. About 25% survive to maturity. All that were examined were males, and about 1/3 of these produced limited...

Abstract

IN the spring of 1948 two silver pheasant hens were inseminated with sperm from a Polish Greenleg cock. Of 27 eggs laid after the inseminations, 2 were broken accidentally. From the remaining 25 eggs, 8 embryos died in the early stages of development, one died on the 6th day, and one on the 10th...

Abstract

The previous published symposium dealt with those aspects of the hen's egg which affect its quality as a food product. This latest one deals exclusively with the egg's reproductive function, and, as such, is concerned with those factors both intrinsic and extrinsic to the egg which affect its...

Abstract

Of 149 eggs obtained from 3 quails (Coturnix coturnix japónica) artificially inseminated with domestic fowl semen, 8 showed embryonic development. The stages of development reached, in terms of the equivalent development of normal quail embryos, were 2-3 days (5 embryos), 5 days (2 embryos) and...
