  1. ARTIFICIAL INSEMINATION OF RABBITS WITH DILUTED SEMEN STORED UP TO 96 HOURS.

    López, F.J.; Alvariño, J.M.R.
    [EN] The effect of different duration's rabbit semen storage at 18ºC (2, 24, 48, 72, and 96 hours) on fertility and prolificacy has been studied in one experiment, where a total of 1447 artificial inseminations have been carried out using a new commercial extender, MA 24. The results indicate a similar fertility (84.14%, 83.56% and 79.73%) when increasing the time of conservation (2, 24 and 48 hours). Difference statistically significant were observed at 72 hours (67.59%) and fertility fell dramatically after 96 hours of conservation (39.23%). The number of total bom kits per litter follows the same tendency than fertility, presenting a light descent in the first conservation...

    Szendrö, Z.; Randai, I.; Biro-Nemeth, E.; Romvari, R.; Milisits, G.; Kenessey, A.
    [EN] For 267 Pannon White growing rabbits of both sexes slaughtered at a body weight of 2.2-2.4, 2.4-2.6, 2.6-2.8, 2.8-3.0, 3.0- 3.2, 3.2-3.4 and 3.4-3.5 kg, the average dressing percentage was 59.5, 60.7, 61.9, 62.2, 61.4, 62.4 and 62.1 % respectively. While the weight of live animals increased by about 50 % between 2.29 and 3.42 kg the change in the weight of blood (23 %), full gastrointestinal tract (26 %) and head (35 %) were the lowest, whereas the intermediate part (65 %), liver (82 %), skin (73 %), meat on hind legs (74 %), meat on the intermediate part (85 %) and perirenal fat (326 %)...

  7. THE EFFECT OF CAFFEINE ADMINISTRATION TO DILUTED SEMEN ON THE PROGENY IN RABBIT.

    BODNAR, K.
    [EN] The effect of two caffeine preparations was studied on the reproductiva parameters (conception rate, litter size and weight, sex ratio of the offspring) in rabbits. In the experiment, Al was carried out on 78 lactating females (divided into 3 groups). Group A was inseminated with diluted semen containing 1 mg Coffeinum Natrium Benzoicum per millilitre, group B was inseminated with diluted semen containing 1 mg Coffeinum Natrium SaHcylicum per millílitre, group e was inseminated with caffeine free diluted semen. The caffeine salicylate improved the conception rate (73.08, 100, 71.88 %) (P<0.01). There was no effect of caffeine on the litter size and weight. In the treated groups...

    Hajj, E.; Boutros, C.; Doumet, W.
    [EN] Parameters of production were registered during 8 months in a Lebanese rabbitry of 55 does and 8 males. Ali rabbits received ad líbitum the same pelleted diet produced for dairy cow (14.5% crude protein, 11.5% crude fibre, 4mm diameter) + alfalfa gay once a day. The breeding stock had no specific genotype and the estimated adult weight was bout 4.0 kg (3.76 kg at 180 days). Forthe 83 controlled litters, the number of boon alive was 5.0 and the number of weaned was 3.0 per litter (30 days). From weaning to the age of 115 days, average daily growth was 25g. Slaughter, performed by the breeder...

  16. PRELIMINARY RESULTS OF INTRA CYTOPLASMIC SPERM INJECTION (ICSI) APPLIED ON RABBIT : A TECHNICAL NOTE.

    Escribá, M.J.; García- Ximénez, F.
    [EN] In a foundation process of a maternal rabbit line using high selection intensities, from sorne hyper prolific females, selected as embryo donors, the subjects were very old and in an unhealthy condition (24%). An in vitro procedure to obtain embryos from this kind of females would be desirable. Sorne technical improvements used for human intracytoplasmic sperm injection (ICSI) have resulted in an enhancement of cleavage rates. This method may be applied to rabbits. Spermatozoa from ejaculated washed semen samples were immobilised in 5% PVP droplet by touching the tail and aspirated tail first into the microinjection pipette. The positioned oocyte was punctured. Sorne ooplasm was aspirated. After rupturing...

  18. PERFORMANCE OF BROILER RABBIT (Soviet Chinchilla x Grey Giant) FED LOW GRAIN CONCENTRATE.

    Singh, P.; Pathak, N.N.; Biswas, J.C.
    [EN] Twenty one broiler rabbits, weaned at 5 weeks of age were divided into 3 groups of 7 each on the basis of body weight in a randomized block design and fed isonitrogenous concentrate mixture(s) containing either 60, 40 or 20% crushed maize grain in group 1, 2 and 3 respectively, alongwith ad libitum kikuyu (Pennisetum c/andistínum) - green grass. In group 2 and 3 replacement of crushed maize was largely done with wheat bran which is available abundantly at lower cost in India. The experiment was continued for 8 weeks ; DM intake and body weight gain were recorded at daily and weekly interval respectively. Body weight...
