Abstract. The aim of the study was to determine effect cow breed, season and type diet on fatty acid (FA) profile raw milk. A 2-year conducted bulk milk samples collected from eight herds consisting Czech Fleckvieh (CF, four herds) Holstein (H, breeds. One half each breed grazed (G), while other not (N). Samples were twice in winter (W) summer (S). Milk yield CF (5385.50 kg) lower than H (7015.15 kg, P < 0.05). found odd-chain, branch-chain hypercholesterolemic FAs (P content fat (S) (W),...
The fatty acid (FA) composition of bulk milk fat was examined on three mountain dairy farms in the Czech Republic. Milk samples were collected period indoor grass silage feeding (November-April) and grazing (May-October). In total fifty FAs identified fat. two-way ANOVA with factors farm sample collection used for evaluation variation FA concentrations. Significant differences between (P < 0.01) found concentration five FAs, which accounted 30.40 g/100 g FAs. sixteen 63.86 content long-chain...
In May 2003 differences in milk fat composition two main dairy breeds the Czech Republic, Pied cattle and Holstein cattle, were studied uniform groups, each containing eight cows. The groups housed together received same daily diet. Fatty acids determined mean samples from individual cows as their methyl esters using a gas chromatography procedure. of fatty acids, namely saturated (SAFA), monounsaturated (MUFA) polyunsaturated (PUFA) ones, examined with acids. was found to contain...
Ten Czech Pied cows in the mid-lactation stage were fed diets based on grass silage and maize silage. The composition of milk fats differed. proportions even-chain saturated fatty acids (SFAs) up to C14:0 insignificant content C16:0 was significantly higher (P < 0.05) when feeding a diet silage, while individual polyunsaturated (PUFAs) (except for C18:2) total SFA 67.60 62.93% silages, respectively, an opposite relation observed sum PUFAs (3.56 4.74%; P 0.001). Feeding resulted lower...
Rapid analytical methods can contribute to the expansion of milk fatty acid determination for various important practical purposes. The reliability data resulting from these routine plays a crucial role. Bulk and individual samples (60 345, respectively) were obtained Czech Fleckvieh Holstein dairy cows in Republic. correlation between (FA) proportions determined by method (infrared spectroscopy mid-region connection with Fourier transformation; FT-MIR) reference (gas chromatography; GC) was...
In 2003, 2004 and 2005 milk fat composition was determined three times in 55 dairy cows of Czech Pied cattle housed a byre with stanchions fed under conditions usual on production farms. Fatty acids were by gas chromatographic method, 26 out the total 37 observed chromatograms identified. The highest proportions for palmitic acid (29.25 ± 2.98%), oleic (24.47 3.27%), myristic (12.14 1.80%) stearic (8.91 2.44%). saturated, unsaturated monounsaturated fatty 64.71 4.18, 31.96 4.20 27.45 3.42%...
Groups of fatty acids (FAs) in milk fat can have positive and negative impact on consumer health.Profi le FAs could be infl uenced by dairy cow nutrition, breed, yield level et cetera.The question is what relationships the to quality products?Relationships between their groups selected indicators were studied Czech Fleckvieh Holstein cows (64 bulk samples).There 8 herds 2-year investigation during winter summer season.The relationship saturated (SAFA; 66.22%) was signifi cant only lactose...
ABSTRACT: Evaluation of fatty acids (FAs) stability in dairy products undergoing technological milk processing is important for subsequent determinations nutritional value. The aim the study was to assess FA composition and its product explore differences profile found yoghurt compared raw material (goat milk). In present study, a reduced proportion volatile FAs (VFA) that cause “goat flavor” reported goat comparison milk. Conversely, an increase medium-chain as well beneficial long-chain...
This study aimed to analyze the factors affecting fatty acid (FA) profile in cow's milk. The effects of a farm, lactation parity and stage, breed polymorphisms AGPAT6, DGAT1, LEP, FASN SCD1 genes were evaluated. A total 196 Holstein cows, 226 Simmental cows seven crosses sampled 751 times. kept at five farms first up sixth lactation, 49 individual FAs 11 groups analyzed. farm significantly affected proportion all except for C16:1n-7c isoC14:0. Additionally, stage was significant most FAs,...
The aim of this study was to evaluate the effect microbial transglutaminase (TG) on processed meat common carp (Cyprinus carpio L.). Three levels (0.5, 1.0 and 1.5%) combined with three NaCl (0, 1 2%), added support binding reaction, were examined. For evaluation quality changes in restructured fish meat, we used textural property hardness water holding capacity (WHC). results confirmed a strong improvement texture after addition salt, whereas 1% TG + seems be best combination from economic...
This study evaluated the effects of four factors (breed, parity, month lactation and feeding ration) on total explained variation (R 2 ) determining composition nutritionally important fatty acids.Individual milk samples were collected times over an entire year (March, June, September, December, respectively) a conventional farm from two breeds: Czech Fleckvieh (dual-purpose, local) Holstein (dairy, worldwide).In total, 145 (36; 38; 35 36, analysed.Within R , ration main affecting acids...
