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...

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

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

Eggs from young turkey breeder hens have a higher rate of early embryonic mortality (EEM) than eggs from older hens. Preliminary field data indicated that increased sperm concentration decreased the incidence of EEM in eggs from young hens. Possible explanations for decreased EEM following ...

Abstract

This paper reviews methods for quantifying breeding efficiency in poultry and the application of these techniques for monitoring commercial breeder flocks. It is suggested that breeding efficiency can be best quantified by estimating the numbers of sperm that interact with the egg in the...

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

Six lots each consisting of 9 Broad Breasted Bronze turkey hens were artificially inseminated during the 1950 breeding season. In the first 2 lots semen was undiluted; in the other 4, a synthetic diluent containing 60 mg. % fructose was used at 0, 24, 48 and 72 hrs. after collection. Mean hatch of...
