AbstractFull Text

Morphological characteristics of turkey Meleagris gallopavo semen were recorded and hatchability percentages of the artificially inseminated hens were assessed. To study the effect of natural mating on hatchability 15 (3♂, 12♀) M. gallopavo were randomly selected, were kept separately and were...

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

The purpose of this study was to evaluate the optimum number of spermatozoa for highest fertility in Ross-308 broiler breeder chicken. About 24 Ross hens in 4 treatment groups were used. Semen was collected from 8 Ross roosters by abdominal massage and pooled in glass tube. After initially dilution ...

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

Hens were: (1) naturally mated, (2) inseminated with undiluted semen, or (3) inseminated with semen diluted with an oviduct extract and stored for 6 hr. Egg fertility of group 2 was greater than that of groups 1 and 3 by 6 and 10.13% resp. ; the corresponding figures for hatchability of eggs set...

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...
