Cheese Production

Summary Organic farming represents agricultural practice that could contribute to the preservation of biological diversity and breeding of cows with the most desired milk quality attributes. Milk composition could vary widely according to genetic diversity of the animals and different feeding systems. These are related to higher dry matter content, fat, protein and a more favorable ratio of the saturated/unsaturated fatty acids, which is important in traditional cheese production. Standard chemical analyzes were performed and this paper shows the differences in the chemical properties and the fatty acid profile of milk, depending on the different breeds and breeding methods of animals. Simmental milk (indoors) was most abundant in dry matter and fat (13.01 and 4.30%, respectively) while protein and casein level was the highest in the Busha milk (3.67 and 2.63%, respectively). Holstein Friesian milk (organic) possessed a more constant composition and, together with Busha appropriate hygienic quality of milk (low level of somatic cells and total bacteria count). Also, milk from Holstein Friesian cows (organic) was disposed with better nutritional quality and more desirable fatty acid profile (SFA (63.40%), MUFA (30.79%) and PUFA (5.72 %)). On the other hand, Holstein Friesian (conventional) milk contained SFA (67.45%), MUFA (29.27%) and PUFA (3.28%) while Simmental (indoors) higher values of SFA (71.21%) and less MUFA (25.39%) and PUFA (3.40%). There are various ways to preserve biodiversity and the application of organic production standards in the traditional cheese production contributes to obtaining safer, quality products which are more recognizable on the market.

Abstract The aim of this study was to determine the effect of Virginia fanpetals (Sida hermaphrodita) silage on the fatty acid profile and the content of selected nutrients and vitamins in the Longissimus lumborum (LL) and Semimembranosus (SM) muscles of young bulls. Forty Polish Holstein-Friesian bulls aged 16 months were assigned to four dietary treatments (n=10) and were fed different types of silage during a 7-month fattening period. The proportion (g/kg dry matter) of silage in the diets was as follows: (1) grass silage (GS) (600); (2) Virginia fanpetals silage (VFS) (600); (3) VFS (300) and GS (300); and (4) VFS (300) and maize silage (MS) (300). Silage was supplemented with concentrate at 400 g/kg DM in each diet. The animals were slaughtered at the end of the fattening period. The intramuscular fat (IMF) of bulls fed GS had the highest (P<0.05) concentrations of n-3 polyunsaturated fatty acids (PUFAs) and linolenic acid (LNA), whereas the IMF of bulls receiving GS and VFS was characterized by the highest proportion of MUFAs, mostly oleic acid (C18:1 cis 9). In comparison with the LL muscle, the SM muscle contained less IMF (by 40%) with a more nutritionally desirable profile. The SM muscle was characterized by a more desirable mineral composition and a higher concentration of α-tocopherol.

The effects of breed and diet containing different types of silages on meat quality parameters and fatty acid profile of m. longissimus lumborum (MLL) were evaluated in a total of 30 Czech Fleckvieh (CF), Charolais (CH) and Charolais &times; Czech Fleckvieh (CH &times; CF) bulls. The animals were fed two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal mixture silage and lucerne silages) with different concentrations of dietary energy and fatty acids. The MLL from CH bulls had the lowest content of dry matter (P &lt; 0.01), less protein (P &lt; 0.01) and lighter meat (P &lt; 0.01) compared to the CF. The extensive LCS diet reduced dry matter (P &lt; 0.01) and intramuscular fat (P &lt; 0.01) and increased the content of hydroxyproline (P &lt; 0.05). The CH bulls exhibited higher PUFA n-3 (P &lt; 0.05) and lower MUFA (P &lt; 0.05) compared to the CF, with the CH &times; CF being intermediate. The LCS diet enhanced the proportions of PUFA (P &lt; 0.05) and PUFA n-3 (P &lt; 0.001) and reduced MUFA (P &lt; 0.001). In conclusion, both breed and diet affected the meat quality and fatty acid profile of the intramuscular fat of the bulls. The replacement of maize silage with the legume-cereal mixture and lucerne silages in the diet reduced the concentration of intramuscular fat and improved its fatty acid profile from the human nutrition perspective.

The aim of the research – is to study the qualitative composition of milk of cows of Ukrainian brown dairy breed in terms of households and in the context of genealogical descent. Method. Research conducted under the conditions of the State Enterprise "Pilot Farm of the Institute of Agriculture of Northern East of NAAS» in Sumy region, Enterprize of Additional Liability “Mayak” in Trostyanetc region, State Enterprise "Pilot Farm Agricultural Firm “Nadiya” of the Institute of Agriculture of Northern East of NAAS» in Romny region. Milk production was assessed by monthly milking control with sampling of milk. Quality indicators measured in the laboratory of the former Sumy State Breeding Center on the equipment of Bentley. We investigated the percentage of fat, percentage of protein, including casein, percentage of dry matter, skimmed residue, contents of somatic cells. Biometric processing of results was carried out by the conventional method (Plohynskoho M.O., 1969), using software Statistica 6.0. The results of the research. Studies have been conducted on the content of fat, protein, casein, lactose and somatic cell count in cow milk. Established difference of qualitative composition of milk of cows depending on the households and on the genealogical origin of the animals. Analysis of our studies indicate that the level of quality indicators of milk production of animals of Ukrainian brown dairy breeds in different farms is significantly different. All the main indicators of quality prevailed in animals of Enterprize of Additional Liability “Mayak”. For the fat content of milk cows of Distinkshna line 159523 were dominated. They though not significantly, but dominated the animals of Eleganta 148551 and Laddi 125640 lines for 0.16% and 0.19% respectively. The substantial significant difference of the content of lactose in the milk of cows of different lines is not set. Animals of Distinkshna line 159523 significantly superior cows of Eleganta 148551 and Laddi 125640 lines for the protein, for 0,24% (P < 0,05) and 0,32% (P < 0,05) respectively. For the casein content they were significantly superior then Laddi 125640 line cows – on 0,24% (P < 0,05). For the dry matter content and skimmed milk residue animals of Distinkshna line 159523 also have the advantage. Conclusions. As a result of studies found that the level of quality indicators of milk production in animals of Ukrainian brown dairy breed in different farms is significantly different. So fat content in milk varies 3,43–3,98%; protein content – 3,10–3,55%; casein content – 2,83–3,31%; dry matter content – 12,4–13,1%, fat-free dry milk residue – 8,95–9,13%. The dependence of milk quality indicators based on linear descent. For the main indices are preferred animals of Distinkshna line 159523.

The influence of modifying a traditional 24-mo dairy steer calf to beef production system on the fatty acid composition of the longissimus muscle and its potential to authenticate beef provenance was examined. Fifty-four male calves (n = 18 per sire breed), progeny of Holstein-Friesian cows mated with Holstein-Friesian (HF), Aberdeen Angus (AA) and Belgian Blue (BB) bulls were at pasture from March until August of their second year when they were assigned to a 3 (breed types) × 3 (finishing strategies) factorial experiment. The three finishing strategies were (i) pasture only for a further 94 d prior to slaughter (21 mo of age) (Grass), (ii) concentrates ad libitum indoors for 94 d prior to slaughter (21 mo of age) (EC) and (iii) pasture only for a further 94 d followed by concentrates ad libitum indoors for 98 d prior to slaughter (24 mo of age) (LC). Compared to EC, muscle from Grass had a lower intramuscular fat concentration and omega-6: omega-3 polyunsaturated fatty acid (PUFA) ratio and higher proportion of conjugated linoleic acid. A longer period at pasture pre-concentrate finishing increased the concentration of omega-3 PUFA which was still lower than in Grass. To maximise the omega-3 PUFA concentration, a late-maturing breed is more appropriate while to maximise conjugated linoleic acid, an early-maturing breed is more appropriate and both should be finished on grass. Chemometric analysis confirmed that the fatty acid profile can authenticate “Grass-Finished” beef per se and has potential to distinguish “Concentrate-Finished” beef based on the length of grazing prior to finishing, but not distinguish between sire breeds.

The objective of this study was to evaluate the fatty acid profile of duodenal digesta (experiment I) and of meat of beef cattle (experiment II) fed diets containing different levels of concentrate (220, 400, 590 and 790 g of concentrate/kg of dry matter of the diets). The experiment I was conducted with four Charolais-Nellore steers (460 ± 18.2 kg of BW), with a T-shaped duodenal cannula, using a double 4 × 4 Latin square as an experimental design. In experiment II, 16 crossbred Charolais-Nellore young bulls (192.44 ± 18.2 kg of BW) were randomly distributed in the experimental treatments (220, 400, 590 and 790 g of concentrate/kg of dry matter of the diets). The diets were isonitrogenous (120 g of crude protein/kg of dry matter). The intramuscular fat content was used as a covariant for the statistical analysis of the meat fatty acid profile. The duodenal content of fatty acid C17:0 decreased with increase of concentrate levels, while its content in the meat presented a quadratic variation with the increase of the concentrate levels of the diets, being the lowest values observed for the diet with 400 g of concentrate. The duodenal content of fatty acid C18:1 trans-11 decreased, whereas the content of this fatty acid in the meat increased with the increase of the dietary concentrate levels. The increase in the level of concentrate reduced the content of polyunsaturated fatty acids C18:3 n-3, C20:3 n-6, C20:4 n-6, and C20:5 n-3 EPA in both the duodenal digesta and meat. No difference was observed in the n-6/n-3 fatty acids ratio (mean of 13.96) of the meat between diets. The elevation of the level of concentrate in confinement diets reduces the nutraceutical quality of the meat of Charolais-Nellore young bulls slaughtered at 14-16 months of age due to the reduction of the polyunsaturated fatty acids content important for human health.

Abstract The aim of this study was to determine the fatty acid (FA) profile of Simmental cow milk in relation to lipid intake in feeds and their composition, and to compare it with FA composition of milk from cows of Polish Holstein-Friesian (PHF) breed. To this end, 104 milk samples were collected from Simmental cows and 52 milk samples derived from PHF breed were taken over a 2-year period. The season significantly influenced both contents of lipid, dry matter and crude protein as well as FA content in lipids extracted from forages. Winter and autumn seasons were characterized by a significantly higher intake of lipids with forages resulting from the intake of fresh silages, compared with the other seasons when the animals were fed stored silages. This was reflected in the highest content of conjugated linoleic acid (CLA) c-9 t-11 C18:2 in milk from the autumn season. Compared with PHF, milk from Simmentals had a higher content of short-chain saturated FAs (SCSFAs) and was characterized by great differences in FA contents determined in the group of odd- and branched-chain FAs (OBCFAs). Milk from Simmental cows had the butyric acid C4:0 and iso C15:0 content of 4.99 and 1.20 g/100 g FA on average, respectively, which have been associated with benefits for human health.

The objective of the study was to compare the chemical composition and fatty acid profile in ten clinically healthy bulls of similar weight from eight meat cattle breeds. The animals were raised by extensive grazing under the same geographical conditions. Significant differences were observed between the monitored genotypes in terms of the dry matter content, nitrogenous matter and fats (P ≤ 0.05) in the musculus longissimus thoracis. The concentration of fats ranged from 68.5 ± 18.81 g (Galloway cattle) to 171.6 ± 43.3 g (Aberdeen Angus) per kg of dry matter. The total content of unsaturated fatty acids ranged from 20.0 ± 2.25 g (Aberdeen Angus) to 42.4 ± 7.87 g (Gascon); the total sum of monounsaurated fatty acids ranged from 17.0 ± 2.26 g (Aberdeen Angus) to 33.8 ± 3.61 g (Gascon); and the total sum of polyunsaturated fatty acids ranged from 3.0 ± 1.42 g (Aberdeen Angus) to 5.1 ± 3.99 g (Limousin) per 100 g of fat. The total content of n-6 fatty acids ranged from 2.4 ± 1.28 g (Aberdeen Angus) to 4.2 ± 3.59 g (Limousin) and the total content of n-3 fatty acids from 0.5 ± 0.16 g (Salers) to 1.1 ± 0.04 g (Gascon) per 100 g of fat. The properties we studied may predict the biological, dietetic, and culinary value of the meat.
