The experiment was set-up using a 3 X 2 X 2 factorial arrangement. Newborn female rabbits were divided on the basis of their birth weight in 3 classes: low /L/=35-45g, medium /M/=53-58g and high /H/=65-70g. Half of the litters were nursed by one (0) doe and the other half by two does (T). Kits were weaned at 3 weeks of age. From the age of 4 weeks half of the rabbits were fed ad libitum (AL), while the other half were reared on a restricted feeding regime (R) corresponding to 80-85% of the ad libitum feed intake level. Birth weight had a significant effect on the body weight up to the end of the experiment (18 weeks of age). H kits attained higher body weight at all ages (3772g at 18weeks of age compared to 3565g and 3373g for L and M rabbits, respectively). Significant differences were found in feed intake between 3 and 15 weeks of age, in feed conversion between 9 and 12 weeks of age and in weight gain between 3 and 4 and 12 and 15weeks of age, in the majority of cases in favour of the H rabbits. Nursing by one or two does exerted the most pronounced effect on the body weight. T kits had significantly higher body weight than 0 kits up to 15weeks of age (3306 vs. 3108g). Differences in feed intake, feed conversion and body weight were only periodically demonstrable between the groups 0 and I The feeding regime exerted a significant influence on the feed intake, weight gain and body weight of kits. Significant differences in the feed conversion were found, however, only between 15 and 18weeks of age. Although AL rabbits achieved better feed conversion at all ages except the period between 9 and 12weeks of age. It seems that the three factors (birth weight, number of nursing does and feeding regime), especially the feed restriction, could influence the production of does. (c) 2006 Elsevier B.V.

Control litters (SS) were nursed once a day for 35 days post partum (traditional method of nursing). DD litters were raised by two does and the kits were nursed both in the morning and in the evening until day 35 post partum. DS litters were nursed twice a day for 23 days, and then once a day until weaning at 35 days. Part of the DS litters were nursed at 08:00 and 20:00 h (i.e. every 12 h, DS12), the rest were nursed at 08:00 and at 16:00 h (DS8). Kits of the fifth treatment (DO) were nursed twice a day until day 23, and then immediately weaned. Rabbit kits that were nursed twice a day (DD, DS12, DS8, DO) consumed on average 1.89 more milk compared with SS individuals until day 23 (overall treatment effect P < 0.001). The 21-day body weight of these young was 1.7 times greater than that of the SS kits (overall P < 0.001). DO rabbits were weaned early and their growth curve showed a slight break at this point. However, they compensated for this lag by the end of the fattening period. SS rabbits and DD ones were respectively the first and the last to start consuming solid food. The food consumption of DS rabbits was similar to that of DD until day 23 and from then until day 35 it was not significantly different from that of SS. After having been weaned on day 23, DO kits consumed only very small quantities of pellets for 2 days. Afterwards their food intake increased abruptly. Rabbits that were nursed twice a day (DD, DS12, DS8 and DO) consumed more food as compared with the SS individuals throughout the total period of fattening (157 v. 137 g/day; P < 0.05). The weight at 10 weeks of age was 2.49 v. 2.88 kg (overall P < 0.001), respectively for SS and double-nursed (DD, DS, DO) rabbits. Nursing twice a day did not affect dressing proportion but the proportion of the carcass in the front part of the body decreased slightly (318 v. 323 g/kg; P < 0.05) while that in intermediate part increased (321 v. 307 g/kg, P < 0.05). Nevertheless, rabbits that were nursed twice a day had more (P < 0.05) perirenal + scapular fat and produced heavier livers. Total fat content of the empty body, however, was not significantly higher, with the one exception of the DD rabbits which had higher levels than any other group. The results of our experiment show clearly that the growth potential of rabbit kits is strongly limited by the milk availability during the first weeks post partum.}, year = {2002}, pages = {117-125}, orcid-numbers = {Szendrő, Zsolt/0000-0002-0359-150X; Milisits, Gábor/0000-0002-4269-910X; Matics, Zsolt/0000-0001-6826-1176} } @article{MTMT:1249914, title = {Effect of birth weight and litter size on growth and mortality in rabbits}, url = {https://m2.mtmt.hu/api/publication/1249914}, author = {Poigner, J and Szendrő, Zsolt and Lévai, A and Radnai, István and Biró-Németh, Edit}, doi = {10.4995/wrs.2000.413}, journal-iso = {WORLD RABBIT SCI}, journal = {WORLD RABBIT SCIENCE}, volume = {8}, unique-id = {1249914}, issn = {1257-5011}, year = {2000}, eissn = {1989-8886}, pages = {17-22}, orcid-numbers = {Szendrő, Zsolt/0000-0002-0359-150X} } @inproceedings{MTMT:1266002, title = {A különböző létszámú almokban nevelkedett anyanyulak termelése}, url = {https://m2.mtmt.hu/api/publication/1266002}, author = {Biró-Németh, Edit and Szendrő, Zsolt}, booktitle = {2.
