[EN] A short description of sanitary problems among argentinean
rabbit farms (25 familiar and 41 cornmercial units), is presented. This
randomized survey was compiled with information provided over the last 5
years by diverse diagnostic laboratories, centres and prívate farmers engaged in this activity. The pathological findings in the 426 autopsied animals, are
similar to those described in the literature. Classical digestive and respiratory
infections accounted for the most important causes of death : 43,2 and
25,8 %, respectively.

[EN] The effect of oxytocin to induce parturition in angora
does was studied. Retrospective observations were made on pregnant
angora does maintained under ideal thermal and photo regulation and
hygienic conditions. They were divided into two groups ; Group 1 (18
does), where oxytocin was used to induce parturition and Group 11 (8
does), where no oxytocin was used. To induce parturition, oxytocin
(Sandoz®) 1 mi was injected intramuscul~rly on the 29th and 3oth days of pregnancy. Parturition occured in 8 of the 18 does between 12 and
30 minutes after injecting oxytocin. The 10 does did not respond to
oxytocin and delivered kits only after two to...

[EN] Mortality rate of young rabbits is of vital importance in
commercial rabbit farming, since it determines the net income of the
rabbitries. However, there is no definite proportion for mortality in young
rabbits, since it may be less !han 10% in one situation in a given breed
and reaches 100% in other situations, in the same breed. This may be
due to susceptibility of the genotype to diseases and to the numerous
uncontrollable externa! environmental factors. The significan!
differences between breeds confirm that mortality can be genetically
improved. Within the same breed, kit mortality during the suckling
period decreases during the period between 4 and 12 months of...

[EN] The aim of this trial was to investigate the effects of high chromium
Cr) yeast supplemented diets on performance of growing-finishing
rabbits. Ninety-six commercial hybrid rabbits, half males and half
females, aged 35 days, were divided into experimental groups and
fed, ad /ibitum, for 49 days the same basal diet supplemented with O
(T1 ), 400 (T2), 800 (T3) or 1600 (T 4) ppb of Cr in the form of
chromium enriched yeast. Control diet (T1) was analysed and found
to contain 789 ppb Cr, a level which was due to the raw feed
materials. The Cr content of all the diets was then proportionally
increased. Chromium supplementation...

[EN] A total of 121 Pannon White female rabbits born with low
(39-43 g) or high (63-70 g) weight were raised in litters of 6 or 1 O kits.
Their reproductive performance (Al practiced 9-11 days after kindling)
was controlled for 6 consecutive litters for a total of 300 kindlings. The
does' birth weight had a significant effect on the number of
inseminations necessary for the first kindling: the higher the birth weight
of does, the lower their kindling rate. Later on, however, birth weight no
longer affected the conception rate. With higher birth weight,
significantly improved doe performance could be expected. Litter size at birth was 12.4%...

[EN] In an eight-week long feeding and digestibility trial, the
acceptable amount of heat-processed ( 1 h boiling) jack bean seed that
can be used to substitute partially for oil cakes (palm kernel and
groundnut cakes) in concentrate diets of rabbits was examined (8
rabbits 7-9 week old of local population per treatment). Four diets were
formulated to contain O, 10, 20 and 30 % jack bean seed, respectively.
The proximate composition of heat-processed jack bean (27.4 % crude
protein, 14.2 % crude fibre and 51.1 % nitrogen free extrae!) showed
that it has potential for use in rabbit feeding. Dry matter intake
significantly declined with increasing levels of...

[EN] The acceptable leve! of inclusion of unthreshed
inflorescence or seedheads of mature grain amaranth plants (GASH)
as feed ingredient of concentrate diets of rabbits was examined. Four
diets were formulated with GASH inclusion levels of O (control), 10,
20 and 30%, respectively, by partially replacing the levels of oil cakes
in the diets. These were fed to rabbits in an eight-week long feeding
trial (8 rabbits/treatment) and a digestibility trials (4 rabbits per
treatment). The initial weight of the 7-8 week old rabbits was 710 g
(adult weight of this population is 1 .8 to 2.4 kg). The proximate
composition (g/kg DM) of GASH was : 151 crude...
