[EN] One hundred New Zealand White rabbits
distributed into five dietary groups were fattened between 35
and 77 days in indivicfuál ca9es. The diets were SOJ
(soybean control), FEV (26.5 % f1eld beans), FEVM (FEV diet
supplemented with di methionine), F'EVF (FEV diet
supplemented with field beans up to a total of 37 %) and
FEVT (FEV diet supplemented with sunflower cake) provided
ad libitum. The mean protein content was 14.5 % in the SOJ,
FEV and FEVM diets and 16.3 % in the FEVF and FEVT
diets. The digestible energy content varied little between
diets (2256 to 2324 kcal DE/ kg). The fibre content of each
diet was 14.5 %....

[EN] The data were collected on sixty New Zealand
White (NZW) and sixty Californian (CAL) weaned male
rabbits used to investigate the magnitude and direction of
genetic environmental mteraction. Ralf the rabbits in each
group was fed ad libitum on commercial pelleted ration
containing Zinc bacitracin (ZIN) and the other half on ration
containing Flavomycin (FLA). F'or all rabbits, daily gain, daily
feed intalromoter type group (n = 15) were slaughtered after 8
weeks from weaning and evaluated for slaughter and carcass

[EN] This paper describes a standardized method for
in vivo determination of total digestibility in rabbits. This
method was working out within the European Group on
Rabbit Nutrition (EGRAN) which involves six laboratories
from five countries (Belgium, France, ltaly, Portugal and
Spain). The aim of the group was to propose a method at
once reliable, quick and- simple. This new rnethod can be regarded as a baseline for calibrating individual laboratory
procedures. The method is based on 7 to 8 weeks old rabbits
caged individually and fed ad libitum. The pre-experimental
period lasts 7 days and the collection period only 4 days. For
either feed and faeces, standardized conditions of...

[EN] The effect of sire strain, feeding plan, slaughter
age and sex on the carcass g~~lity were studied on 120
crossbred rabbits (White Giant (vvG), Heavy Grimaud Fréres
(HGF), Light Grimaud Fréres (LGF) with New Zealand White
does]. Two feeding plans were used : plan H consisting of a
high energy diet (10.42 MJ DE/kg ; 12.14 % DP) from
weaning to slaughtering (75 days or 90 days of age) ; plan
LH consistíng of a low energy d1et (9.85 MJ DE/kg ; 11.51 %
DP) until 55 aays, and a higfl energy diet up to 75 or 90 days.
The sire strain affected growth performance and carcass traits...

[EN] Thirty two laboratory strain New Zealand White
rabbits aged about 6 weeks were divided into 4 equal groups.
Rabbits were fed diets of 9. 73 % (/DM) fibre in group 1 and 2,
and 12.86 % fibre in group 3 and 4. Yeast culture
(Saccharomyces cerevisiae) ata rate of 5 x 1oa cells /animal
/day was given orally to group 1 and 3. Dry matter intake was significantly (P<0.01) higher in the rabbits given high fibra
diet but tlie digestibility coefficients of dry matter, organic
matter, ether extract, nitrogen free extract and feed
conversion efficiency were significantly better in the animals
given low fibre diet. Adminisfration of yeast...

[EN] Using a 3-factorial design, the effect of two
commercial diluents (IMV vs Minitüb), two storage times
(fresh vs 6h storage at ambient temperature) and a lighting
schedule was stud1ed on artificial inseminated does. During a
1 O month experimental period 140 (nulliparous and
multiparous) does were randomlr divided in two production
groups and submitted to a 16h :8hD continuously lighting
schedule or to a 10hL:14hD schedule. In order to
synchronize the oestrus, the lighting period was suddenly
increased till 16hL from 5 days before the insemination
(alternative lighting). Both production groups were
inseminated every a weeks with an interval of 3 weeks
between them. In total 988 inseminations were performed

[EN] Segregation patterns, reproduction rate,
mortality, fattening performance and gut parameters of albino
(ce) ralfüits heterozygous (Enen) or homozygous (EnEn) for
the English Spot gene have been investigated to test the
hypothesis whether albinos can suffer from MegacolonSyndrome,
which is a characteristic predisposition of EnEn
spotted animals. Whereas the weight of the gut (brutto) of ce
Enen - animals reached 8.5 ± O. 7 % of live weight at slaughter and 17 .2 ± 1.6 % of the carcass weight, ce-En En
animals exhibited a relativa gut weight of 16.5 ± 6.5 % and
37.0 ± 17.4 % respectively. rn addit1on to these findings one
cc-EnEn breeder buck suffered chronically...
