Abstract

This review deals with the dilution, freezing, cryoprotection, thawing and post-thawing treatment of fowl and turkey semen and the effect of freezing on semen fertilizing ability. [For Pt. 1 see Archiv für Tierzucht (1993) 36, 431-442].

Abstract

Data on 1048 eggs from hens inseminated at 3- to 4-day intervals over 6 wk (group 1) and 758 eggs from hens inseminated at 7-day intervals over 4 wk (group 2) were analysed. The overall egg fertility and hatchability was 74.5 and 63.0% resp. for hens in group 1 vs. 55.2 and 43.5 in group 2, embryo...

Abstract

1306 hens were inseminated intravaginally with frozen semen from a single ♂. For hens inseminated with 0.2 ml frozen semen (trials 1 and 2) diluted with a glycerol extender, the av. egg fertility was 2.0 and 10.7% resp. vs. 17.4% for hens inseminated with 0.4 ml (trial 3), and in the 3 groups, the...

Abstract

Turkey semen diluted with ethylene glycol or N,N-dimethyl acetamide (DMA) was frozen slowly (by 1°C/min to -30°, standard method) and stored in liquid nitrogen, was frozen rapidly to -40° and stored in liquid nitrogen, or was frozen in pellets and stored in dry ice; the different treatments were...

Abstract

In a comparison of the Blumberg diluent with the Beltsville extender, semen stored for 6 h before use gave an egg fertility of 95.7 and 88.2% resp., and a hatchability of fertile eggs of 81.0 and 75.1%. When the Blumberg diluent was used with an insemination interval of 7 and 14 days, egg fertility ...

Abstract

Semen was diluted in a raffinose-glutamate-inositol-lactose-fructose diluent (diluent I) or in a glutamate-fructose-magnesium acetate-potassium acetate-PVP diluent (diluent II), and were pellet frozen with glycerol (8% final concentration). After thawing, the glycerol was removed by centrifugation. ...

Abstract

In May-July, semen was obtained twice weekly from 5 male turkeys. Undiluted semen was stored for 30 min. at 22 deg C, was diluted 1:3 with a fructose-yolk-glycerol diluent, placed in medium-sized straws, cooled to 5 deg in 3 h, and frozen in liquid nitrogen vapour. The semen was thawed at 37 deg...

Abstract

When pooled semen from 40 males was diluted 1:1 in a solution containing 7.5% ethylene glycol, sperm motility averaged 71.0% v 81.1 for undiluted semen, egg fertility percentage 57.3 v 66.7, and the hatchability percentage of fertile eggs 77.8 v 78.6. Samples frozen to various temps. from -2 deg to ...

Abstract

60 cocks and approx. 1200 hens belonging to the White Rock and New Hampshire breeds were used. 119 mixed semen samples were prepared from over 1500 ejaculates. The freezing method of Watanabe et al. [see ABA 38, 4363] was used. The forward motility of spermatozoa frozen by this method, and stored...
