[EN] The supplementation of diets for rabbits with copper
has been restricted in the EU to 35 mg/kg. In our experiment,
quadruple concentration of Cu added to a pelleted diet as
CuS04.5H,0 was used to investigate effect of Cu feeding on Cu
concentration in muscles, liver, ha ir and faeces of Hyplus® rabbits.
The main ingredients of the basal diet were alfalfa meal, wheat
bran, sunflower meal, oat, barley, sugarbeet pulp and soyabean
mea l. Six rabbits, 35 days of age at the beginning of the experiment,
were fed basal diet (containing 1 O mg Cu/kg), and six rabbits were
fed Cu-supplemented diet. Cu concentration in faeces was

[EN] The objective of this study was to examine the
relationship between velocity and fertility of rabbit sperm, using
low sperm numbers per insemination. Semen was collected weekly
for 5 weeks from two fertile males. To study the effect of high
dilution of sperm in media without macromolecules, each semen
sample was split with one portien retained as whole semen, and
the remainder was centrifuged and washed with saline. The washed
sperm were resuspended with seminal plasma (SP), phosphatebuffered
saline (PBS), or PBS containing 1 % (wt/vol) of bovine
serum albumin (BSA). Each week two non-lactating does per buck
were each inseminated at the cervix with 0.5 X 106 total...

[EN] Feedstuff tables are presentad including the
composition and the nutritiva value of 53 raw materials used in
compound diets for intensively reared rabbits. Each raw material
is characterised by 23 analytical data and its digestible protein
and energy values. Because of the importance of the fibre fractions
in the nutrition of the rabbit, special efforts have been done to
characterise the carbohydrate complex. The digestibility data were
selected after a compilation of original literatura data and a discussion between the authors. The methodology used, in the
different in vivo assays, was evaluated accurately in order to judge
the reliability of the data. Besides digestible and metabolisable
energy values are...

[EN] Oxidative processes in meat lead to meat quality
deterioration. Meat has endogenous antioxidants and prooxidants.
Our objective was to study the activity of the antioxidant enzymes
in two different lines of rabbit and its variation through refrigerated
storage. Twenty rabbits from two synthetic breeds selected for
different criteria (litter size and growth rate) were used in this
experiment. The activity of catalase, glutathione peroxidase (GSHPx)
and 2-thiobarbituric acid-reactive substances (TBARS) were
measured during 5 days of storage at 4°C in Longissimus dorsi (LO) and the set of muscles of the hind leg (HL). Catalase and
GSH-Px activities were higher in HL than in LO. The activity of

[EN] To evaluate the effects of starch level and source on
growth performance, caecal fermentation, and carcass and meat
quality, six diets were formulated including different percentage of
barley (B) or corn (C) or equal proportions of the two cereals (BC)
to obtain moderate (M) or high (H) starch levels, and fed to 96
rabbits from 35 d of age until slaughter (73 d). Within starch level,
B and C diets presented similar chemical composition and nutritive
value while starch digestibility was higher in B diets. The starch
source did not affect growth performance and meat quality and
showed weak effects on caecal fermentation, apart from a higher proportion...
