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

Frozen-thawed rooster semen is not reliable for use in artificial insemination in commercial stocks. Low-density lipoprotein (LDL) has been assessed for effectiveness as a cryoprotectant in the extender to improve the quality of frozen-thawed rooster semen. Although LDL has been evaluated in a few...

Abstract

Sperm motility is used to predict the semen quality and fertilization ability of breeder roosters. Indigenous chicken breeder roosters show variation in sperm motility, but less has been known about its relationship with other reproductive attributes. In this study, 40- to 44-wk-old Beijing-You...

Abstract

The population of red jungle fowl is declining and needs special attention for its conservation with suitable approaches. For ex situ in vitro conservation of Indian red jungle fowl, establishment of semen cryobank is an appropriate option, for which an extender with adequate retrieval capacity for ...

Abstract

A specific problem in goat semen preservation is the detrimental effect of seminal plasma on sperm viability in extenders containing yolk or milk. Thus, the use of chemically defined extenders will have obvious advantages. Although previous studies indicate that the initial pH of an extender is...

Abstract

The immxinisation of hens with semen (intravenous injection) or a semen + adjuvant emulsion (intramuscular injection) did not significantly lower egg fertility for 2-7 days after insemination compared with that in non-immunised controls, but 8-14 days after insemination fertility was significantly...

Abstract

A method of semen collection by massage is described and illustrated. The method was effective in 80% of ♂♂ Ejaculate volume, semen pH and sperm concentration averaged 0.0073 ml., 7.2 and 1.447 x 106 per ml. resp. Spermatozoa lost their motility within 10-15 mins. of collection.-F.S.

Abstract

Over a long period, White Leghorn (W.L.), Barred Plymouth Rock (B.P.R.) and crossbred hens were repeatedly inseminated with semen from W.L., B.P.R. and White Cornish (W.C.) ♂♂. Egg fertility declined as the period of artificial breeding increased, particularly with W.C. ♂♂. Sperm agglutinin titre...

Abstract

Semen was easily collected by the massage method using a bird holder designed by the authors. A diagram of this, with measurements, is given. Data are tabulated on the semen characters of a White Holland ♂ over a 7-mth. period. Average values for ejaculate volume, sperm concentration per mm.3 and...

Abstract

The optimum concentration of sodium citrate in the diluent was 3. 0-3. 5% when it involved 11 molecules of combined water and 2. 5-3. 0% when it involved 2 molecules. It was approx. 0. 1 mol in concentration and 1. 015 in specific gravity in both cases. The freezing point depression most suitable...
