The aim of the study was to determine the biodiversity of flies (Diptera) occurring in livestock buildings and in their direct proximity, in various systems of ruminants rearing. Flies were collected by net sweeping during the summer, in two cowsheds (one large-scale, and one traditional farm), and one specialist sheepfold, located in the Lesser Poland region of Poland. The insects were captured –...
The aim of the study was to assess the quality of pastures located in less-favoured areas (LFA) of Czech Republic, to evaluate the influence of that quality on the content of fatty acids of milk in grazing goats and in farm natural cheese made of their milk. Samples of forage were collected in 2008 and 2009, on 5 July, 9 August, 6 September and 4 October. Goat milk samples were taken on the same days...
The fatty acid (FA) composition of bulk milk fat was examined on three dairy farms applying the seasonal pasture and on two farms applying the permanently indoor silage feeding. The seasonal variation in the content of major FAs was investigated in relation to the effect of farm in each feeding system separately. Six samples in winter period and four samples in summer period were taken on each farm...
Celem pracy było określenie składu kwasów tłuszczowych w tłuszczu śledzia atlantyckiego (Clupea harengus) po kolejnych etapach produkcji marynat zimnych oraz w okresie składowania. Badania przeprowadzono na mrożonych filetach ze śledzi atlantyckich (n = 320) złowionych w strefie połowów FAO 27 na Morzu Północnym, które do zakładu produkcyjnego przywieziono w postaci głęboko zamrożonych (-18 °C) 15...
The aim of the study was to determine optimal pre-slaughter handling procedures (individual or group housing) for various slaughter cattle categories. Subjects were 842 Black-and-White Polish Holstein-Friesian slaughter cattle, classified into four EUROP categories – bulls up to 24 months of age (A), bulls older than 24 months (B), cows which had had offspring before (D), and heifers (E). Slaughter...
Used were 15 bulls and 15 heifers of the Black-and-White Polish Holstein-Friesian breed, semiintensively fattened, with the aim of evaluating the effect of sex on the selected traits of quality of beef. Bulls were slaughtered at the mean age of 536.2 days and 523.1 kg body weight, and heifers at 528.7 days and 459.7 kg body weight, respectively. After slaughter and post-slaughter treatment,the carcasses...
