The trial was designed in order to examine the impact of flax seed in the nutrition of young cattle/bulls, in the final stage of the fattening. In the trial, 30 bulls of Simmental breed of uniform initial weight were selected, divided into 2 groups (control and experimental). The control animal group did not consume flax seed as a food supplement. Cattle of the experimental group consumed flax seed in an amount of 3.75% (300 g per day) of concentrated meal in the last 90 days of fattening, i.e. 300 g per day. The study included the examination of the fattening performance, slaughter traits and the composition of the bovine carcass. After slaughtering, warm carcass sides, with and without kidneys, were measured individually. Subsequent to period of cooling, the left carcass side it was cut into the main carcass parts according to the Rulebook. The results of the study showed that the addition of flax seed in the diet did not have a statistically significant effect on the body weight of bulls at the end of the trial. It was found that the addition of flax seed in the feed during the final stage of fattening did not have an impact on the differences in the average overall gain of bulls and the feed conversion ratio. Based on the data obtained by cutting of carcass sides to main parts, it was established that feeding with flax seeds had no significant effect on the share of carcass parts. Eksperiment je postavljen sa ciljem da se ispita efekat dodavanja semena lana, u ishranu junadi, u završnoj fazi tova. Za ogled je odabrano 30 muških junadi simentalske rase ujednačenih početnih telesnih masa, koja su podeljena u 2 grupe (KON (kontrolna) i FS (ogledna)). Kontrolna grupa junadi nije konzumirala seme lana kao dodatak ishrani. Junad ogledne grupe su konzumirala seme lana u količini od 3,75% (300 g dnevno) koncentrovanog dela obroka u poslednjih 90 dana tova, tj. 300 g dnevno. Istraživanje je obuhvatilo ispitivanje rezultata tova, klanične karakteristike i sastava trupa junadi. Nakon klanja izvršeno je pojedinačno merenje toplih polutki sa i bez bubrežnog loja. Posle hlađenja leva polutka je rasecana u osnovne delove prema Pravilniku. Rezultati istraživanja su pokazali da dodatak semena lana u ishrani nije imao statistički značajan uticaj na masu junadi na kraju ogleda. Utvrđeno je da dodatak semena lana u ishranu tokom završne faze tova nije imao uticaj na razlike u prosečnom ukupnom prirastu (PUP) junadi i konverziji hrane. Na osnovu podataka dobijenih rasecanjem poluki junadi na osnovne delove utvrđeno je da ishrana sa semenom lana nema značajan uticaj na udeo delova trupa.

Background High dietary sodium intake can induce endothelial stiffness even without changes in blood pressure. Objectives To evaluate the effects of exercise training and chronic intake of sodium chloride solution on aortic morphology of male offspring of rat dams who consumed flaxseed during lactation. Methods Female rats were fed with a control diet or a flaxseed diet during lactation. At weaning, two male offspring of each rat dam were allocated into eight groups for 180 days: four groups received a control diet e four received a flaxseed diet, with /without exercise and with/without NaCl solution supply. Aorta was collected for histomorphometric analysis. The one-way analysis of variance was used and P value < 0.05 was considered statistically significant. Results The chronic use of 1% NaCl solution led to changes in aortic histoarchitecture in the control group: increase in aortic intima-media thickness (10,4%, p
