The experiment was carried out on 40 Polish Black-and-White HF bull calves (52-87% of HF blood) aged from 9 and 12 days at the beginning of the experiment to 90 days at its end. From the beginning of the trial the calves were offered restricted liquid feed to 56 days of age and concentrates ad libitum according to IZ-PIB-INRA recommendations. The concentrates were without sodium butyrate (control group, C), or with 1% Na-butyrate (group B1), 3% Na-butyrate (group B3) and 0.3% Na-butyrate (group B0.3), and included meadow hay from 0.10 kg/day during the liquid feeding period to 0.20 kg/day after weaning at 57 days of age. Na-butyrate at 3% in the diet reduced feed intake and had a beneficial effect on calf growth and nutrient utilization. The dietary level of Na-butyrate did not cause significant changes in serum β-hydroxybutyric acid concentration of the calves.

The aim of the study was to evaluate the effect of replacing cereal grains and soyabean oilmeal with rapeseed cake or glycerine in the rations of high-yielding cows. The experiment was carried out on 56 Polish HF cows allotted to 4 groups of 14 animals according to body weight, milk yield, and parity. The cows were fed rations differing in protein and energy content from 6 weeks before calving to 12 weeks of lactation. The basal diet of all groups was composed of silages, meadow hay and concentrate feeds. In the experimental groups, the cereal grains and soyabean oilmeal fed to the control group (C) were replaced by rapeseed cake (30%; groups RC and RCW6 ) or glycerine (5%, group G). For the entire experimental period, no statistical differences were found among the groups in the daily intake of dry matter and other nutrients, except PDIE. The control group cows produced about 1.2 kg/day less milk (P>0.05), but the contents of dry matter, fat, protein, lactose, and urea in milk were similar. The highest concentration of free fatty acids and β-hydroxybutyric acid were found in the milk of the control cows. Introducing 5% glycerol into the diet did not cause any significant changes in production parameters. The serum metabolite profile of cows fed the experimental diets suggests that these cows could have been at a lower risk of ketosis.

The experiment was performed to determine whether transgenic maize containing the Bt gene (MON 810) and soyabean meal produced from glyphosate-tolerant plants (Roundup Ready, MON 40-3-2) compared with nontransgenic plants can affect the performance parameters, milk composition, blood serum metabolite profiles and transfer of tDNA into milk of cows. The experiment was carried out from the third week before parturition to the 305th day of lactation on 40 Polish Holstein-Friesian cows, which were allotted to 4 groups of 10 animals according to body weight, milk yield and parity. The cows in all groups were fed a total mixed ration (TMR) formulated according to IZ-INRA (2009). The concentrate mixtures added to TMR contained: nonmodified (traditional) maize and soyabean meal (group TMG/TS); traditional maize and genetically modified (GM) soyabean meal (group TMG/MS); GM maize and traditional soyabean meal (group MMG/TS); or GM maize and GM soyabean meal (group MMG/MS). There were no significant differences between transgenic and non-transgenic feeds in productivity, milk composition and blood metabolite profiles such as: β-hydroxybutyric acid (BHBA), free fatty acids (FFA), glucose, insulin and progesterone. The transgenic DNA sequences of MON 810 and RR soyabean meal were not detectable by PCR in milk

Na glebie mineralnej, kompleksu żytniego dobrego w RZD w Minikowie, w latach 1992 - 1997 prowadzono badania nad trwałością, plonowaniem i wczesnością 70 odmian 14 gatunków traw pastewnych. Najwyższą trwałością charakteryzowały się odmiany kupkówki pospolitej, tymotki łąkowej i kostrzewy trzcinowej, a szczególnie małą kostrzewy łąkowej życicy trwałej. Najwyższe plony uzyskano, przy 4.1etnim użytkowaniu stokłosy uniolowatej, rajgrasu wyniosłego, kupkówki pospolitej i tymotki łąkowej, a różnice w plonowaniu odmian wahały się na poziomie 10 - 20%. Największe różnice we wczesności odmian wykazano u odmian kupkówki pospolitej, kostrzewy trzcinowej i życicy trwałej. Największą wrażliwość na niedobory opadów i wysokie temperatury stwierdzono u późniejszych gatunków, a w obrębie gatunków również u późniejszych odmian.

The experiment was performed to determine whether genetically modified maize (MON 810) and soyabean meal (Roundup Ready, MON 40-3-2) used as the main source of feed in a concentrate can affect the performance parameters, basal chemical composition of the musculus thoracis (MT), fatty-acid composition of intramuscular fat, and transfer of transgenic DNA (tDNA) to calf tissues, as well as affect the results of histological examination of calf organs and tissues. In the experiment, forty Polish Black-and-White HF bulls aged 10 days were allocated to 4 groups fed non-modified (traditional) maize and soyabean meal (group TMG/TS), non-modified maize and GM soyabean (group TMG/MS), GM maize and non-modified soyabean meal (group MMG/TS), or GM maize and GM soyabean meal (group MMG/MS). The experiment was terminated at the age of 90 days. Calves were housed in individual pens and fed ad libitum diets with balanced energy and protein according to the IZ-INRA (2009) system. All mixtures contained similar amounts (%) of maize (56), soyabean meal (25), oat (15), premix and limestone (1). There were no major differences in the feed value of Bt maize and RR soyabean meal and their non-modified isogenic counterparts and feed mixtures. There were no effects of GM components on final liveweight, average daily weight gain, MT chemical composition, or fatty-acid profile of intramuscular fat. The calf rumen fluid contained tDNA, but there was no tDNA in the intestinal content, blood, studied organs, or meat. Histological examination of the investigated organs and muscles found no differences among treatments.

Histopathological examination of liver, kidney, spleen, pancreas, duodenum, jejunum, skeletal muscle, and bursa of Fabricius samples, collected from broiler chickens, laying hens, fattening pigs, and calves fed genetically modified corn MON 810 and soybean meal MON-40-3-2 (Roundup Ready, RR), was performed. The examination showed no significant differences between the control animals fed diets containing no genetically modified feeds and animals fed genetically modified feeds. In some cases, congestion of parenchyma and focal lymphoid cell infiltrations were observed in all dietary groups, including controls, and therefore, it was assumed that the lesions were not associated with the feeding transgenic feeds.
