A discussion on the recommendations and status of the conservation breeding programme from the committee of breeder's association such as the German Society for animal breeders was presented. Highlights focused on the problems and the need for appropriate action.

Body fat content of Pannon White growing rabbits was determined at 10 weeks of age using an EM-SCAN SA-3152 type Small Animal Body Composition Analyser (TOBEC method). Based on the fat content determined, the best and worst 16% of does and the best and worst 8% of bucks were chosen and mated with...

The new edition of this comprehensive textbook of artificial insemination has appeared seven years after publication of the first edition. The new edition has been thoroughly revised and updated, and is longer than its predecessor by 150 pages. Twenty-eight authors have contributed to the book,...

Data on approx. 400 inseminated New Zealand White rabbit ♀♀ in Hungary were analysed. Conception rate and litter size at birth were significantly affected by season of insemination, ranging from 62.0% and 7.18 resp. for ♀♀ inseminated in Aug.-Sep. to 94.1% and 8.63 for those inseminated in...

The performance was compared of 3970 progeny of ♀ rabbits inseminated 1-2 or 10-12 days post partum, and which were reared by their dam or by another ♀. Birth weight was significantly higher for the offspring of ♀♀ inseminated within 2 days of parturition than for those of ♀♀ inseminated later....

In 2 experiments carried out in the main breeding season (winter months up to end of Mar.) and in other months, groups of mature ♀♀ (30 and 105 ♀♀ per group in the 2 periods resp.) were given 0, 10, 20 or 40 μg GnRH immediately after natural mating. Outside the main breeding season, CRs in the 4...

288 ♀ rabbits were inseminated in Jan., Apr., July or Oct. with fresh or frozen semen from 6 ♂♂. There were no significant differences between months in semen characters, but ♀♀ inseminated in July and Oct. had significiantly lower CRs than those inseminated in Jan. or Apr. Litter size was not...

After each of 10 consecutive kindlings, 27 New Zealand White rabbit does were inseminated with 1 ml rabbit semen diluted 1:8 with a Tris diluent after being injected with 10 mu g of LHRH (Lutal R) or 0.4 mu g of the Hoe 766 LHRH analogue. The inseminations were carried out at intervals of 32-35...

A new, simplified glass instrument is described and illustrated. Based on the knowledge that vaginal temp. is an important trigger of the ejaculatory reflex, the new equipment maintains a temp. of 42 deg C.

The procedures used of induction of ovulation, collection and processing of semen, and insemination are described. Using these techniques, litters are born within 1-2 days of each other, and the CRs of 80-100% can be achieved.
