ABSTRACT
Measurement of adaptability and stability of a breed in
different environmental conditions might be assumed as good indicator for
ecological, ethological and ethical norms in animal production. Indeed, a good
adaptability and stability in reproduction performances, in a given environment,
can be assumed as a proof that animals are in good well-being condition. The aim
of this study was to assess adaptability and stability indexes for fertility
traits of four local chicken breeds (the Ermellinata di Rovigo: PER, the
Pèpoi: PPP, the Robusta Lionata: PRL and the Robusta Maculata:
PRM) reared in three different environments (mountain, hill and plain areas) of
the Veneto region. Data consisted on 338 hatchings recorded from February 2002
to May 2004. The percentages of fertile eggs per hatching (pFE), non-hatched
eggs per hatching (pNH) and percentage of chicks born alive (pBA) were used as
dependent variables. An ANOVA for each reproduction trait was performed to
estimate genotype by environment (GxE) interaction. A high GxE interaction was
detected for all reproduction traits in particular for pBA. The PER was the best
breed in terms of adaptability and stability. On the contrary, the breed that
showed to be poorly adapted to all environments and scarce stability over time
was PPP. The PRL and PRM seem to be more similar to PPP than PER. In conclusion,
more study on GxE interaction should be done to obtain more information on
adaptability and stability of animal breeds in different environmental and time
period conditions. Animal welfare and relationship between animal and
environment should be known and subsequently used for defining better norms and
rules for a modern animal production activities.

ABSTRACT
The aim of our investigations was to study the ability of heavy
type turkey genotypes developed for intensive systems using semi extensive
(aviary) and extensive (free-range) systems and the effect of the different
environment on the performance. The semi extensive conditions appeared to be
well adapted to the technology of producing high performance heavy type turkey
and it does not cause decrease in the production parameters. In the case of the
carcass yield also disadvantageous changes are prognosticable. The live weight
of the intensively and semi extensively reared groups did not differ
significantly prior to slaughtering, but in the case of male turkey the outdoor
keeping achieved a 40% lower bodyweight in a 4 weeks longer period than the
males in the other two systems. In the case of females the difference was lower
but the performance also showed a 20% decrease in the outdoor system. The
carcass yield showed a decrease in both of sexes of the free-ranged turkeys but
it was statistically significant (P<0.01) only in the case of females. The ratio
of the breast fillet of the female turkeys in the free-range system was higher
than in the other groups. The heart – as an important organ of the maintenance
of the physiological functions – weight ratio was not affected by the rearing
conditions but compared to the grill – ready body weight it was found to be
incredibly low. Our results confirm the hypothesis that the heavy type hybrids
are able to adapt to the extensive environment but a longer rearing period
results only in a significantly lower final bodyweight. Regarding the carcass
yield disadvantageous changes are predicted in the case of both sexes.

ABSTRACT
In the case of goose liver production the adoption of EU
regulations means that new technologies should be developed instead of force
feeding. One of the potential alternatives is the pinguefaction due to
periodical feeding, which needs the modification of the feeding behaviour of the
goose. The first step of the selection for this character is the examination of
the behaviour differences between the adaptable genotypes. In this study the
behaviour of two goose strains (white and grey) was compared during the
preconditioning period. Based on our results, the behaviour of the two genotypes
showed significant differences in the appearance frequency of feeding, drinking
and preening. However resting and social behaviour also diverged but the
differences were not statistically significant.

ABSTRACT
The aim of the experiment was to study the effect of the
nutrient supply of suckling and growing rabbits on productive traits. The
experiment was set-up using a 2x2 factorial design. Half of the litters were
nursed by one doe and the other half by two does. Kids were weaned at 3 weeks of
age. From the age of 4 weeks each group was halved and one part was fed ad
libitum (AL) and restricted feeding (RF) was applied for the others. The
productive traits of 136 nursing and growing rabbits were examined. The nursing
method affected the kids’ body weight but the difference between groups was
significant only till 4 weeks of age (443 and 523g, P<0.05). The daily weight
gain and feed intake were independent of the number of nursing does but the feed
conversion between 6 and 9 weeks of age was significantly superior to kids
nursed by one doe (2.99 and 3.29 g g–1, P<0.01). The effect of
feeding scheme was significant on feed intake and weight gain from 4 weeks and
on the body weight between 12 and 16 weeks of age. The feed conversion was
better between weeks 9–12 in AL while between weeks 12 and 16 in RF group. The
body weight of rabbits in groups of AL nursed by two does and RF nursed by one
doe were 1042 and 950, 1875 and 1763, 2671 and 2502, 3549 and 3392 at the age of
6, 9, 12 and 16 weeks, respectively.

ABSTRACT
In Hungary there is a new opportunity to use mixtures of green
fodder crops for ruminant nutrition. Joining the EU there is a subsidy for
cattle breeders who prefer the extensive way of breeding. The objective of this
paper is to determine which plant species and varieties could be used in the
green fodder feeding system. The small plot trials with spring barley, oat, pea
and vetch were performed in four repetitions. We used the following mixtures of
temporary certified seeds: oat & pea, oat & vetch, barley & pea, barley & vetch,
sunflower & pea. Immediately after the harvest yields of fodder from
plots were weighted and the samples were analysed for dry matter, crude protein
and crude fibre. The yields of green fodder, dry matter and crude protein were
calculated in tons per hectare. In 2002 the green fodder yield was highest with
Bakonyalja (oat) and Eszter (vetch) mixtures (45.95 t ha–1), but the
highest crude protein yield was given by Annabell (barley) mixed with Rubin
(pea) (1040 kg ha–1). In 2003 yield of Annabell and Rubin mixtures
was higher than yield of Bakonyalja mixed with Rubin (e.g. crude protein yield
513; 403).

ABSTRACT
Mycological investigation in 11 winter barley samples was
performed. All of barley samples were infected with moulds. The ratio of
infected kernels varied from 11.7% (sample SSK8) to 13.0% (sample SSK9) after 14
days of incubation. The fungi were isolated from kernels and they were
classified into 6 genera and 11 species. Genus Fusarium was presented
with the highest number of species (5). F.poae, a toxigenic species of
the genus Fusarium, was present in all samples tested. The highest ratio
(about 66%) of all mycopopulations belonged to genus Alternaria spp. All
barley samples contained zearalenone, but the concentration was low (from 5.2 to
52.0 mg kg–1).

ABSTRACT
In October 2002 Slovenian veterinary administration confiscated
312 dogs from one private animal collection. Of them 287 were able to be
transfered in a provisional shelter Lahovo. We studied dog’s behaviour,
prospects for socialization and rehoming, and monitored their health status. The
most common behaviour characteristic in Lahovo was fearfulness, which was
observed in 59.6% of dogs. 40.7% of dogs needed veterinary care, flea
infestation was 100%. During the month of their stay at Lahovo 185 dogs were
transferred to certified shelters in Slovenia, Austria and Germany. 99 dogs were
rehomed from Lahovo to Slovene adopters. 63.3% of these dogs were fearful
immediately after the adoption and 30% were still fearful seven months later.
Other common behaviour problems were eating anomalies in 65.2% and sleeping
disorders in 18.8% of dogs. In addition to flea infestation, the most common
health problems immediately after adoption were digestive problems in 51.1%,
dental problems in 51.1% and ear infection in 50% of dogs. After seven months of
individual handling of the dogs their behaviour disorders and health problems
reduced or disappeared.
