Abstract

A modification of the introduced Makrotüb method was used for semen freezing. The investigated characteristics of fresh semen of the Arab stallions were in the normal range. However, the semen data obtained from the Haflinger stallions were markedly and partially significantly in lower range than...

Abstract

In a preliminary trial with frozen semen, 57 ewes were (1) inseminated intra-cervically once, 12-24 h after signs of oestrus, (2) inseminated once, after 24-36 h, (3) inseminated twice after 12-24 h or (4) inseminated twice after 24-36 h. In the 4 groups resp., 89, 50, 70 and 64% of the ewes...

Abstract

For 131 sows inseminated with frozen semen in 1985, the CR was 39.7%, and the total number of piglets born per litter averaged 10.0, of which 9.5 were liveborn vs. 52.6%, 9.4 and 8.9 for 293 sows inseminated in 1984. An account is given of methods of freezing and thawing of semen, and of the...

Abstract

In 1986, in the German Democratic Republic, 404 106 ewes were inseminated, representing 62.5% of the total population vs. 356 821 ewes, representing 55.0% of the total, in 1980. The CR was 62.5% in 1986 vs. 60.4% in 1980. Research on the effects of semen diluents, duration of semen storage, semen...

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

Semen from 9 boars at the Neustadt/Aisch AI Centre was frozen by the method of Westendorf, Richter and Treu [see ABA 44, 753] in Hulsenberg straws. Of 73 sows inseminated under farm conditions, 44 farrowed, with an av. litter size of 9.0. Some pilot laboratory experiments were also carried out. The ...

Abstract

Bull semen was diluted in Laiciphos A and B, boar semen in SH1 (bicarbonate-citrate-EDTA) followed by further dilution in egg yolk-lactose-glycerol (EYLG), and stallion semen in EYLG. The semen was frozen in straws in alcohol + dry ice or in liquid nitrogen vapour. The best post-thawing sperm...

Abstract

Using the routine thawing medium for semen pellets, based on lactose, the 60- to 90-day NR rate to 1st insemination in 300 cows was 68.7% v 72.7 for a similar number of cows inseminated with pellets thawed in a sodium citrate-glucose solution.

Abstract

During 3 breeding seasons, semen was collected by digital manipulation. The semen was of excellent quality and, after freezing and thawing, the number of motile spermatozoa exceeded 60%. In 2 trials with vaginal insemination, no pregnancies were obtained. In the 3rd experiment, surgical ...
