AB  - Central Serbia has a long tradition of cattle farming and, as a
hilly-mountainous area it favors rearing of dual purpose Simmental breed, and to a
lesser extent, Holstein-Friesian dairy breed. The first Herd Book of Serbia was
founded in 1935. The high quality breeding animals registered are under the
control of production performance properties. According to expert report of the
Institute for Animal Husbandry and the results of the implementation of the
breeding program in 2018 in the territory of Central Serbia, there were a total of
153.979 quality breeding animals of Simmental and 16509 quality breeding
animals of Holstein-Friesian breed in the main herd. Both breeds are of national
interest and are included in the breeding-selection program for dairy cattle that are
implemented through the cooperation of breeders and breeding organizations in the
field. In Central Serbia, there are 157 registered breeding organizations involved in
breeding and livestock recording activities. In this paper, data of the Head breeding
organization in cattle farming, the Institute for Animal Husbandry, as well as
reports issued by the same entity each year were used. A tabular analysis and a
five-year trend are presented according to: the number of recorded animals,
primiparous females in linear evaluation, the realized yield of milk, milk fat and
protein, as well as the trend of the number of bull dams in the population. Based on
the analysis of the results of work on cattle breeding and selection, it can be
concluded that some progress has been made in milk production of both breeds. It
is important to emphasize that there is a significant effect of mentioned factors on
the productivity of entire cattle population in Central Serbia. Systematic work on
the breeding and selection of cattle is an important work that should be carried out
in high quality, continuously and appropriately in order to achieve maximum
effects in cattle production.

AB  - Modern methods for assessing the welfare of dairy cows are, among other things, often based on the evaluation of animal behaviour. In this regard, behaviour is classified as the most reliable, so‑called animal‑based indicator as its expression comes from the animal itself and indicates a measure in which it has adapted to the environment. Starting from the need to explore the state of welfare and the ability to demonstrate adequate behaviour in dairy farms in Serbia, the Welfare Quality® Assessment Protocol for Cattle (2009) was used in this study. The overall assessment of behaviour was carried out by analysing four main criteria: social, other forms of behaviour, human‑animal relationship and emotional state. The results of the study conducted on a total of 16 dairy farms (N = 4,833 cows) show that the conditions for ensuring appropriate behaviour meet only minimum standards and that the greatest welfare risks arise from the impossibility of expressing natural behaviour, such as exploratory behaviour. The most pronounced negative tendencies within the assessment of the emotional status were those expressed to distress, frustration and boredom. Although the estimated general condition does not differ substantially from the same on EU farms, the need for its improvement is imposed first of all in terms of ensuring greater freedom of movement and more stimulating environment in cattle rearing.

AB  - The aim of this research was to investigate the influence of the
bull i.e. genotype on the observed traits of semen quality and to determine whether
there are significant differences between bulls in terms of semen production. The
study included 9 bulls of the Holstein-Friesian breed from the Livestock Center of
PKB Corporation. The effect of the bull on certain semen properties (ejaculate
volume, sperm concentration, sperm motility in the native ejaculate, sperm
dilution, number of doses per ejaculate, sperm motility after thawing) was analyzed
and data were collected during 2014. During this period, a total of 326 ejaculates
from 9 bulls were collected and average values for the tested properties were
determined and the effect of the bull on those properties was analyzed. The results
showed that there was a very significant effect of the bull (p<0.001) on the degree
of sperm dilution and the number of doses per ejaculate. Significant influence
(p<0.01) was found in ejaculate volume traits, sperm concentration, sperm motility
in the native ejaculate, while in sperm motility after thawing no significant effect
(p> 0.05) of the bull was determined. The LSD test (Least Significant Difference)
was used to compare the bulls and the results of this test showed in most cases
significant differences between the bulls.

AB  - Due to the ecological concerns and preservation of genetic
resources, the characterization of genetic structure of the brown trout (Salmo trutta)
was carried out on the "Braduljica" fish farm. DNA was isolated from fin clips of
10 individuals, and after that molecular PCR-RFLP methods were used for
distinguishing between Atlantic and Danubian lineages based on control region of
the mitochondrial DNA (CR mtDNA) and lactate dehydrogenase gene of the
nuclear DNA (LDH nDNA). Based on phenotypic characteristics it was estimated
that out of 10 individuals included in this study five belonged to the allochtonous
Atlantic lineage and remaining five belonged to the native Danubian lineage of
brown trout. However, results of molecular analyses showed a high percentage of
allochthonous genes among the individuals, which confirms the hybridization
between these two lineages. Also, the results showed that the selection based on the
phenotype is not adequate. In order to continue with proper broodstock
management, it is necessary to eliminate allochtonous individuals of the Atlantic
lineage from the broodstock.
