“…The breeding of the two most common dairy breeds, H and CF, in the Czech Republic relies on two feeding strategies: a pasture-based feeding system with a seasonal pasture from May to October followed by silage feeding indoors for the rest of the year, and a silage-based feeding system with the indoor silage feeding without any access to pasture throughout the year (Frelich and Šlachta, 2011). Concerning the total SFAs, our results are in agreement with many studies comparing pasture-based and silage-based feeding systems (Frelich et al, 2009(Frelich et al, , 2012Kirchnerová et al, 2013;Shingfield et al, 2013); however, there are some differences in the effect of feeding system on individual SFAs.…”

Abstract. The aim of the study was to determine the effect of cow breed, season and type of diet on the fatty acid (FA) profile of raw milk. A 2-year study was conducted on bulk milk samples collected from eight herds consisting of Czech Fleckvieh (CF, four herds) and Holstein (H, four herds) breeds. One half of the herds of each breed was grazed (G), while the other half was not (N). Samples were collected twice in winter (W) and twice in summer (S). Milk yield in CF (5385.50 kg) was lower than in H (7015.15 kg, P < 0.05). The effect of breed was found in odd-chain, branch-chain and hypercholesterolemic FAs (P < 0.05). The content of fat was lower in summer (S) than in winter (W), being 3.71 and 3.91 g 100 g −1 , respectively (P < 0.05). The proportion of saturated and polyunsaturated FAs was lower in S than in W (P < 0.05). The content of monounsaturated FAs was higher in S (30.69 g 100 g −1 ) than in W (27.72 g 100 g −1 , P < 0.05). Milk yield in grazing herds (G, 5197.50 kg) was lower (P < 0.05) than in non-grazing herds (N, 7203.75 kg). The sum of saturated and hypercholesterolemic FAs was lower and the sum of monounsaturated and odd-chain FAs was higher in G than in N (P < 0.05). Content of conjugated linoleic acid (CLA) and C18:3n3 was higher in G (0.93 and 0.64 g 100 g −1 ) than in N (0.42 and 0.39 g 100 g −1 , respectively, P < 0.001).

The effect of the combined grazing and cutting management on the phytocenological characteristics was examined at the submountain paddock in the South Bohemia. The botanical scans were sampled during the five-years study (2006–2010) starting after the sowing the pasture sward in the originally arable field and 0–2 years after the beginning of the grazing (paddock A and paddock B, respectively). The paddock A was grazed all year round, whereas the paddock B was grazed in spring and autumn and cut in summer for hay. At both paddocks, Lolium perenne, Trifolium repens and Taraxacum sect. Ruderalia dominated the community of total 43 and 47 species (paddock A and B, respectively). Among the sowing species, Lolium perenne, Festuca pratensis, Poa pratensis, Festuca rubra and Trifolium repens increased its cover on both paddocks, while Phleum pratense increased its cover only at paddock B. Lolium multiflorum decreased it cover at both paddocks. Most of arable field weeds disappeared (paddock A) or decreased its cover (paddock B). The cover of herb layer was higher at paddock A than at paddock B, whereas the number of species (N), the diversity (H) and the equitability (J) was higher at paddock B than at paddock A. The cover of herb layer increased during the study at both the paddocks, while the number of species declined at paddock A and increased at paddock B.

There were examined 161 cows from 4 farms in total. The suspect animals were selected according to viscosity test results, clinical symptoms and somatic cell count (SCC). Milk samples were examined for the presence of pathogens and for SCC. 55 mastitis pathogens were identified. The most frequently isolated species was Enterococcus faecalis (n = 20), followed by Staphylococcus aureus (n = 6) and Streptococcus uberis (n = 5). The SCC ranged from 9 to 24 204 ths.ml−1. There was positive occurrence of bacteria genus Staphylococcus and Enterococcus at lower SCC (50 ths.ml−1) and at higher SCC numbers (> 300 ths. ml−1) bacteria genus Streptococcus, Enterobacter and Escherichia coli. Differences in SCC were significant (P < 0.001) in negative samples xg 131 SCC versus 491 for positive, 611 for staphylococci and 464 ths.ml−1 for other positive. SCC discrimination limit for practical likelihood of pathogen occurrence estimation in infectious sample groups was calculated. This limit for suspicion of infection is 159 for positive group, 113 for staphylococci and 174 ths.ml−1 for other positive. This could be possible to recommend the value 174 ths.ml−1 for practical use with target to apply preventive or curative measures.
