ABSTRACT
Genetic and environmental parameters for 38 983 test-day
records of daily milk yield (DMY), fat (FC) and protein (PC) content,
collected between 1994 and 2002, were estimated on 3,068 dairy ewes of the
three Slovenian breeds. A multivariate restricted maximum likelihood method
was used for estimation, where every test-day record was treated as a
different trait. Fixed part of the multitrait animal model for DMY, FC, and
PC included breed and lambing season as classes, while stage of lactation,
parity, and litter size were covariates. Random part of the model contained
additive genetic effect and the effects of flock test month and permanent
environment over lactations. Heritability estimates for individual test-days
were between 0.10 and 0.23 for DMY, 0.09 and 0.18 for FC, and 0.19 and 0.28
for PC. The flock test month effect explained most of the phenotypic
variance: 0.18 to 0.41 for DMY, 0.26 to 0.45 for FC, and 0.24 to 0.44 for
PC. A lower variance ratio was explained by the permanent environment effect
over lactations: 0.09 to 0.15 for DMY, 0.02 to 0.11 for FC, and 0.02 to 0.09
for PC. Additive genetic correlations between individual test-days were high
in all three milk traits for adjacent months of lactation. They decreased
when the interval between months of lactation increased. The structure of
additive genetic correlations showed that the observed milk traits in the
different stages of lactation were genetically not the same trait, since the
correlations between distant months of lactation were lower than one

ABSTRACT
A total of 11 ruminal strains currently assigned to
Butyrivibrio fibrisolvens and Pseudobutyrivibrio xylanivorans
were cultivated in two different media, rumen fluid containing M2 and
short-chain fatty acid (SCFA) containing M330, and their cellular fatty acid
methyl esters (FAME) and dimethylacetals (DMA) were analyzed using gas
chromatography. A comparison of the FAME/DMA compositions revealed that the
difference in SCFA contents in the growth medium induced a pronounced
quantitative effect on the cellular branched-chain fatty acid and aldehydes
proportions only in the P. xylanivorans
strains. This study shows that FAME/DMA analysis is a powerful
chemotaxonomic tool in the group of phenotypically similar rumen
butyrivibria especially when the influence of the growth medium is evaluated

Common agricultural policy Health Check: the

ABSTRACT
The article analyses Common agricultural policy (CAP)
Health Check (HC) negotiations process and outcome. It proposes realist,
structural economic model, based on Moravcsik’s liberal intergovernmental
theory, which has distinct conceptual and methodological characteristics
from major theoretical models on recent CAP reforms. Instead of focusing on
institutionally embedded European policy-making, it is proposed that
national interest articulation process is relatively autonomous, that common
decisions are determined through two level distributional bargaining games
and that policy changes are essentially underpinned by global development of
competitive forces. Research is focused on formal statements and positions
expressed by actors involved in the process, on economic rationale of
different mechanisms and on CAP’s economic effects on different interest
groups. Analysis which heavily draws from specialized first and second hand
resources supports the proposed model. It is concluded that state-structured
decision making and economic forces development are driving CAP reforms
towards greater national flexibility in targeting and financing

Introduction of positive

ABSTRACT
The paper presents the key results of the doctoral
dissertation by Kožar (2010), which introduced the method of positive
mathematical programming (PMP) in sector modelling of Slovenian agriculture
in order to enrich the set of empirical tools for quantitative impact
analysis of economic and political changes on Slovenian agriculture. CAPRI
modelling system, a comparative static partial equilibrium model of European
agriculture was applied. The model enables impact assessment of different
policy and economic scenarios at the aggregate level of EU27, at the level
of Member States groups, Member States or NUTS 2 regions and by individual
products. The second goal of the dissertation was to test the introduced
approach by comprehensive regional analysis of production and economic
impacts of implementing two scenarios of long-term reforms of CAP pillar I
direct payments policy on Slovenian and European agriculture. Model results
show that the abolition of direct payments would result in drop of the
baseline income by 17 % at the aggregate EU27 level. The impacts can be less
favourable for individual Member States groups, Member States and regions,
depending on the share of premiums in income from agriculture,
specialization and competitiveness of production. The most pronounced and
the least favourable production impacts are projected for suckler cows. At
the level of EU27 suckler cow herd size will drop by 6 % in case of both
scenarios compared to the baseline. The most influential is the drop of the
herd size in Spain and France as it influences EU27 average and causes the
whole chain of impacts for other products. Slovenia is among those, which
will be faced with less favourable impacts. The model results could be
underestimated due to the fixed land market and due to the nature of
modelling production decoupled payments.

ABSTRACT
To compare the sensorial quality of wild and farmed brown
trout 34 consumer were asked to decide which of the two samples presented to
them in double blind test was preferred regarding appearance, aroma,
juiciness, mouth feeling and general impression if difference in mentioned
traits between both samples was detected. Results showed that for all traits
at least 75% of consumers stated that they noticed difference. For
appearance and aroma wild trout was preferred, for juiciness and mouth
feeling farmed trout was favored. General impression of wild brown trout was
favored by 15 consumers, while 16 consumers regarding this trait preferred
farmed brown trout. Meaning and importance of results from consumers’ panel
test for positioning of products from fish farming and fishery is discussed.

ABSTRACT
The aim of our study was to examine average duration and
frequency of behaviour of growing rabbits and possible influence of gnawing
sticks as environmental enrichment on their daily rhythm of behavioural
patterns duration. For this purpose 16 males of Slovenian sire line SIKA for
meat production were recorded 24 hours per day, between 45 and 48, 58 and
61, 72 and 75, and 86 and 89 days age of rabbits. Animals were housed
individually in wire-mesh cages equipped with a feeder and a nipple drinker.
Half of the cages were enriched with wooden sticks of Norway spruce (Picea
abies). Animals had free access to the feed and water; the daily
duration of lighting was 12 hours. Rabbits spent a major proportion of time
resting (59.03%). They were lying most of the time in abdominal (38.84%) and
abdominal – lateral position (18.05%). The most common active behavioural
patterns were body care (sum of grooming and scratching; 20.16%), feeding
(10.25%) and sniffing (4.60%). Rabbits changed their behaviour on average
53.55-times, from three to 197-times per hour. The difference in daily
rhythm of individual behavioural pattern duration between rabbits in
enriched and control cages was mostly expressed around the time lights were
turned on or off

ABSTRACT
Comparative analysis of applicable Slovenian legislation
governing the protection of animals used for scientific purposes with
Directive 2010/63/EU has been conducted. The European Union Member States
are required to transpose the relevant Directive into their respective
legislation by November 10, 2012 at the latest, and to begin the application
thereof as of January 1, 2013. Directive 2010/63/EU is based on the
requirement for strict observation of the 3R principles, i.e. the principles
of replacement, reduction and refinement in breeding,
keeping and use of animals in procedures. The paper presents in relevant
tables the comparison of applicable provisions in the Slovenian law with the
novelties laid down in Directive 2010/63/EU, which will need to be
incorporated into the legal order of the Republic of Slovenia. In addition,
tables show optional provisions in Directive 2010/63/EU which, however, are
not necessary to be incorporated into the legal order of the Republic of
Slovenia. The currently applicable provisions that may be retained in the
legal order of the Republic of Slovenia, as they are ensuring a higher level
of protection of animals intended for use in experimental procedures are
included as well.
