  1. THE EFFECT OF DOE-LITTER SEPARATION ON PRODUCTION PERFORMANCE IN RABBIT DOES AND THEIR KITS

    Szendrõ, Zs.; Jovánczai, Zs.; Theau- Clément, M.; Radnai, I.; Bíró- Németh, E.; Milisits, G.
    [EN] Pannon White does were subjected to artificial insemination between 9 and 11 days subsequent to kindling (no. of Al = 931 ). Controlled suckling was systematically applied from O to 18 days post partum. In addition to the control group (group C, n = 236), the does of the three experimental groups were prevented from suckling on the day prior to insemination (48h doe-litter separation, or MLS). The following day sorne of the does were inseminated two hours before suckling (B-2, n = 229), sorne immediately after suckling (B-0, n = 234), and sorne two hours after suckling (B+2, n = 232). The effect of biostimulation led to...

  3. REARING MANAGEMENT OF RABBIT DOES : A REVIEW

    Rommers, J.M.; Kemp, B.; Meijerhof, R.; Noordhuizen, J.P.T.M.
    [EN] Under the curren! management strategies, young does are not able to mee! the high energy requirements for concurren! pregnancy and lactation during the first litters, resulting in nutritional deficits, decreased reproductive performance and a high replacement rate. Feed intake capacity seems to be the main limiting factor. According to literature it seems impossible to adequately solve this problem by taking management measures during the reproduction period. The rearing period seems to be the bes! time to influence body development and feed to optimize the reproductive performance of young does. This is because of the rapid development of organs and tissues al an early age. The present review firstly summarises literature...

  5. IN VIVO ESTIMATION OF BODY FAT CONTENT OF NEW-BORN RABBITS USING THE TOBEC METHOD

    Milisits, G.; Gyarmati, T.; Szendrõ, Zs.
    [EN] An EM-SCAN SA-2 type Small Animal Body Composition Analyser (TOBEC) was used to determine the total conductivity index (E value) of 50 new-born rabbits. After the TOBEC measurements the animals were slaughtered and their bodies were homogenised by grinding twice; fat canten! was then determined by a chemical procedure. A weak correlation (r=-0.09) was obtained between E value and body fat percentage. Due to the high correlation between E value and body weight (r=0.90), estimated fat canten! was corrected far this trait [CF(%) = 11.7 - 0.1127 x (1.61 x (BW - BW;) +E;)], resulting in a marked improvement in the correlation (r=0.51) between predicted and measured fat...

  7. GROWTH PERFORMANCE, SLAUGHTER AND CARCASS COMPOSITIONAL TRAITS IN RABBITS OF A LOCAL STRAIN AND NEW ZEALAND WHITE BREED RAISED IN BURUNDI

    ANOUS, M.R.
    [EN] A total of 77 males rabbits represented the Local rabbits (L) of Burundi and the New Zealand White (NZW) breed were used to evaluate the genetic differences among the two genotypes in live performance, slaughter and carcass compositional traits and to show the possibility of integrating the Local rabbits with the NZW breed in the Burundian rabbit industry for meat production. The rabbits were slaughtered al an average age of 12 weeks. Results showed that from 3 to 12 weeks of age the NZW breed produced significantly heavier animals and grew significantly faster than those of the Local strain at all ages considered in the study (1948 vs...

  9. EFFECT OF REPLACING PEANUT MEAL BY NEEM (Azadirachta Indica) SEED KERNEL CAKE ON NUTRIENT INTAKE, DIGESTIBILITY AND RETENTION, AND ON BODY WEIGHT OF BROILER RABBITS

    Wasanthakumar, P.; Sharma, K.; Sastry, V.R.
    [EN] Performance of broiler rabbits was assessed on equinitrogenous and equi-caloric composite diets (25 roughage : 75 concentrate) incorporated with graded levels (O, 5, 1 O and 20%) of neem seed kernel cake (NSKC) in order to replace peanut meal (PNM) moiety of reference die!. Twenty-four Soviet Chinchilla and 24 White Giant rabbits were assigned to treatments in a randomized block design between 6 and 12 weeks of age. Dietary variation did not significantly influence the digestibility (8 rabbits /die!) of most of the nutrients except ADF (from 20.6% in the control down to 17.7% with 20% of NSKC). Though rabbits fed NSKC beyond 10% retained lesser (P<0.01) nitrogen,...

  12. EFFECT OF DOE-LITTER SEPARATION ON SURVIVAL AND GROWTH OF YOUNG RABBITS

    Alvariño, J.M.R.; Bueno, A.; Santiago, M.E.; El Arco, J.A.
    [EN] The effect of doe-litter separation on growth and mortality of young rabbits was studied at two different ages: 4 or 11 days. A total of 325 litters were used in this work. Experimental groups were composed with litters separated from their dam for O, 24, 36 or 48 hours before the artificial insemination, performed on day 4 or 11 post partum. The separation lasting 36 or 48 hours clearly affected growth especially in 4 days old rabbits. A decrease of rabbit weight was observed after 48 hours separation on 4 days (20%, P<0.001) as well as on 11 days (13%, P<0.07). The negative effect on growth...

  13. EFFECT OF A 48H DELAYED INSEMINATION WITH OR WITHOUT A 48H DOE-LITTER SEPARATION ON PERFORMANCE OF NON-RECEPTIVE RABBIT DOES

    Bonanno, A.; Alabiso, M.; Di Grigoli, A.; Alicata, M.L.; Leto, G.
    [EN] The effectiveness of delayed artificial insemination (DAI) of non-receptive (R-) does, with or without oestrus synchronisation by doe-litter separation (MLS), was studied and compared with receptive (R+) does. During 10 months, 105 NZW does, in three homogeneous groups (A, B, C), were artificially inseminated (Al) according to a 42-day reproduction rhythm in two batches. Every 21 days, two Al were effected, the second 48 hours alter the first. The R+ does of ali groups were inseminated al the first Al, while the R- does were treated, in relation to theirgroup, as follows: inseminated at the first Al (A); 48-hour DAI (B); 48-hour MLS by closing the nestbox before...

  14. EFFECT OF A 48 HOURS DOE-LITTER SEPARATION ON RABBIT DOE'S REPRODUCTIVE PERFORMANCE AND OFFSPRING'S GROWTH

    Virág, Gy.; Kustos, K.; Szabó, L.
    [EN] Artificial insemination of lactating does at 10-11 days after parturition poses difficulties to achieve high fertility rate. lt would be importan! to overcome this constraint because shortening the interval between two parturitions would have an economic advantage. In this study, 308 inseminations of 90 NZW does overa six-parity period were evaluated to determine the effects of a 48 hours of doe-litter separation (S group) compared to the free suckling (R group) on does reproductive performance and on the growth of the actually nursed litter. Ali litters were equalised at 8 kits per litter on day 1 post partum. For the separated group, the kindling rate showed an overall...
